Raspberry Pi 5 Proxmox Cluster: Build a 3-Node ARM Homelab for Under $300

Reading time: ~22 minutes Audience: Homelab builders who want a silent, low-power cluster; x86 veterans curious about ARM viability; makers and tinkerers ready to move beyond single-Pi projects

Introduction: ARM Homelabs Are No Longer Toys

The homelab community has a long memory. For years, running Proxmox on a Raspberry Pi was a party trick — technically possible, practically useless. The Pi 4’s 4GB RAM ceiling made it a novelty. Container images were x86-only. And the idea of clustering multiple ARM boards into a coherent hypervisor fleet? That was the stuff of YouTube experiments, not production homelabs.

The Raspberry Pi 5 changed the math. With 8GB of LPDDR4X RAM, a quad-core Cortex-A76 at 2.4GHz, native PCIe 2.0 x1 for NVMe storage, and — critically — Proxmox VE’s official arm64 ISO support arriving in 2025, the question flipped. It’s no longer can you run a Pi cluster. It’s when does it make more sense than a used x86 server.

This guide walks through building a 3-node Raspberry Pi 5 Proxmox cluster from zero to production-ready — complete with PoE networking, shared storage, LXC containers, and ARM Docker compatibility. Total hardware cost: under $300. Total noise: zero decibels. Total power draw: roughly what a single x86 server burns at idle.

What You’ll Get

Component	What It Does
3× Raspberry Pi 5 (8GB)	Proxmox VE nodes — ARM64 hypervisor cluster
PoE+ HATs + PoE Switch	Single-cable power and networking for all nodes
Ceph Distributed Storage	Shared storage across all three nodes (or NFS for simplicity)
ARM64 LXC Containers	Lightweight services: Pi-hole, Uptime Kuma, n8n, WireGuard
ARM Docker Compatibility	Multi-arch-aware container deployment with fallback strategies

Why Build an ARM Homelab Cluster in 2026?

The Pi 5 Has Enough RAM for Real Workloads

The Raspberry Pi 5’s 8GB model is the inflection point. Where the Pi 4 topped out at 8GB with a slower memory controller, the Pi 5 pairs 8GB of LPDDR4X-4267 with a 4× Cortex-A76 core complex that benches roughly 2.5× faster than the Pi 4 in multi-threaded workloads.

What does 8GB per node buy you in practice?

Workload	RAM per Container	Containers per Node (8GB)
Pi-hole DNS	256MB	~20+
Uptime Kuma monitoring	512MB	~10
n8n automation	1GB	~5
Vaultwarden	512MB	~10
Nginx reverse proxy	512MB	~10
Nextcloud (light)	2GB	~2
Jellyfin (direct play)	2GB	~2

A 3-node cluster with 24GB total can comfortably host 15–20 LXC containers while leaving headroom for Ceph’s memory requirements. That covers the full self-hosted starter stack: DNS, reverse proxy, password manager, monitoring, automation, and media — with room to grow.

Proxmox VE Now Supports ARM64 — Officially

Prior to Proxmox VE 8.2, ARM support was unofficial at best. You could compile from source or use community-maintained images, but the experience was fragile — kernel panics on reboot, missing KVM modules, and no clustering support.

The Proxmox VE 8.2 release (Q2 2025) shipped with first-class arm64 ISO images. This means:

Official installer — flashable with Raspberry Pi Imager or dd
Corosync cluster stack — works on ARM for quorum-based node management
LXC on ARM64 — container templates built for aarch64
ZFS on ARM — supported on NVMe drives via the Pi 5’s PCIe HAT
Web GUI — the familiar Proxmox interface, identical to x86

The one caveat: full KVM virtualization (VMs) does not work on ARM. Proxmox on Pi 5 is an LXC-only hypervisor. For a homelab running containerized services, this is perfectly fine — LXC gives you isolated Linux environments without the overhead of full virtualization. But if you need to run Windows VMs or non-Linux operating systems, stick with x86.

Power Consumption vs. Performance Math

This is where the Pi 5 cluster makes its strongest argument. A single used Dell R730xd with dual Xeons idles at 120–150W. A 3-node Pi 5 cluster with PoE HATs idles at roughly 18–22W total — about the power draw of a single LED light bulb.

Configuration	Idle Power	Peak Power	Annual Cost (₿0.12/kWh)
3× Pi 5 (8GB) + PoE HATs	18–22W	35–40W	~$23
Dell OptiPlex Micro (i5-8500T)	15–20W	65W	~$21
Dell R730xd (2× E5-2680 v4)	120–150W	350W	~$150
HP EliteDesk 800 G4 (i7-8700)	25–35W	95W	~$37

The Pi 5 cluster nearly matches the single OptiPlex on power — but gives you three physical nodes for high availability, distributed storage, and quorum-based clustering. If any single Pi fails, the cluster keeps running. If a single OptiPlex fails, everything goes dark.

For deeper hardware comparisons, see our homelab server hardware guide.

Each Pi connects to the PoE switch via a single Ethernet cable carrying both power and data. The Corosync cluster communication network runs over the same physical link (for a 3-node home cluster, a dedicated Corosync ring isn’t necessary — but we’ll cover how to add one for production).

Bill of Materials (BOM) — Exact Parts and Pricing

Item	Model / SKU	Qty	Unit Price	Total
Raspberry Pi 5 8GB	SC1112	3	$80	$240
PoE+ HAT	Official Raspberry Pi PoE+ HAT	3	$25	$75
NVMe SSD	Samsung 980 500GB NVMe (via PCIe HAT)	3	$45	$135
PCIe NVMe HAT	Pineberry Pi HatDrive! Top	3	$20	$60
PoE Switch	TP-Link TL-SG1005P 5-Port Gigabit PoE+	1	$45	$45

Cooling	Official Active Cooler	3	$5	$15
Case / Mount	Custom 3D-printed rack or Argon EON	1	$30	$30
Total				$645

Wait — that’s not under $300. The $300 target comes from the core compute: 3× Pi 5 8GB ($240) + PoE switch ($45) = $285. The NVMe drives, HATs, and microSD cards are storage and boot media that you may already own or can add incrementally. If you boot from microSD and use NFS for shared storage (instead of Ceph on NVMe), the functional cluster starts at $300.

The full $645 build gives you Ceph-distributed NVMe storage — the equivalent of a 3-node x86 cluster with redundant SSDs that would cost 4–5× more and consume 10× the power.

Power Budget at the Wall

Measured with a Kill-A-Watt meter, each Pi 5 node with PoE+ HAT and active cooler:

State	Per Node	3-Node Total
Idle (no containers)	6.2W	18.6W
Light load (5 LXC containers)	8.5W	25.5W
Medium load (10 LXC + Ceph OSD)	11W	33W
Peak (all cores at 100%)	13.5W	40.5W

A 3-node cluster running a typical homelab workload hovers around 25–30W. That’s less than the idle power of most x86 rack servers — and completely silent.

Step 1: Flash Proxmox VE to Pi 5

Download the ARM64 ISO

Proxmox VE 8.2+ provides an official arm64 ISO. Download it from the Proxmox downloads page:

# On your desktop/laptop
wget https://enterprise.proxmox.com/iso/proxmox-ve_8.2-arm64.iso
sha256sum proxmox-ve_8.2-arm64.iso  # verify checksum

Flash with Raspberry Pi Imager

The Raspberry Pi Imager (available for Windows, macOS, and Linux) is the simplest method:

Insert your microSD card (128GB A2-rated recommended)
Open Raspberry Pi Imager
Choose “Use custom” and select the Proxmox VE arm64 ISO
Select your microSD card
Click Write

Alternatively, use dd from the command line:

sudo dd if=proxmox-ve_8.2-arm64.iso of=/dev/sdX bs=4M status=progress conv=fsync

Important: The microSD card is boot-only. All Proxmox data, container storage, and VM images will live on the NVMe SSD. The microSD card only holds the bootloader and /boot partition.

First Boot and Network Configuration

Insert the microSD card into Pi #1, connect Ethernet (through PoE HAT or directly), and power on
Wait 2–3 minutes for first boot (Proxmox resizes filesystems on initial startup)
Find the IP address from your router’s DHCP lease table, or connect a monitor + keyboard
Access the Proxmox web interface at https://<pi-ip>:8006

On first login (username: root, password: the one you set during install), configure a static IP:

# Edit /etc/network/interfaces
nano /etc/network/interfaces

Set a static configuration:

auto eth0
iface eth0 inet static
    address 192.168.1.10/24
    gateway 192.168.1.1

Apply with systemctl restart networking and verify with ip a.

Step 2: Configure the First Node (Master)

Create the Cluster

From the Proxmox web GUI on Pi #1 (your master node):

Navigate to Datacenter → Cluster
Click Create Cluster
Set a cluster name (e.g., pi-cluster)
Choose the Corosync link — use the primary network interface (eth0) for simplicity
Click Create

The cluster creation is near-instant on ARM64. You’ll see a confirmation with the cluster name and node count (1).

Set Up Corosync Network

For a 3-node Pi cluster on a single switch, Corosync runs over the same physical network as management traffic. This is fine for homelab use. If you want to add redundancy later, you can configure a second Corosync ring on a dedicated VLAN or a USB Ethernet adapter:

# Add a second ring (optional — for production only)
pvecm add <node-ip> --ring1_addr <secondary-ip>

Verify cluster status:

pvecm status

Expected output:

Cluster: pi-cluster
Quorum: Yes (1 node)
Nodes: 1

Add Storage — USB SSD or NVMe HAT

Proxmox on Pi 5 supports several storage backends. For LXC containers, you need somewhere to store container images:

Storage Type	Setup Complexity	Performance	Cost	Recommended?
NVMe SSD (PCIe HAT)	Medium	800+ MB/s	$45	✅ Best — low latency, ZFS support
USB 3.0 SSD	Low	350 MB/s	$40	✅ Good — simple, widely compatible
microSD only	Lowest	50 MB/s	$15	❌ Avoid — slow, wears out fast

With an NVMe drive attached via the PCIe HAT:

# Verify the drive is detected
lsblk
# Should show nvme0n1

# Create a ZFS pool
zpool create -f -o ashift=12 tank /dev/nvme0n1

# Add as Proxmox storage
pvesm add zfspool tank --pool tank --content images,rootdir

With a USB SSD:

# Verify
lsblk  # should show sda

# Create ZFS
zpool create -f -o ashift=12 tank /dev/sda

# Add to Proxmox
pvesm add zfspool tank --pool tank --content images,rootdir

Storage is now ready for LXC container deployments. For more on Proxmox storage configuration, see our Proxmox beginner guide.

Step 3: Add Nodes 2 and 3 to the Cluster

Join Command and Token

On the master node (Pi #1), generate a join token:

pvecm updatecerts --force
pvecm addnode pi-node2 --nodeid 2

Actually, the cleaner workflow is through the GUI:

On Pi #1, go to Datacenter → Cluster → Join Information
Click Copy Information — this copies the join command with embedded token
On Pi #2, open the Proxmox web GUI
Go to Datacenter → Cluster → Join Cluster
Paste the join information
Enter the master node’s root password
Click Join

Repeat for Pi #3 (node ID 3).

Verify Cluster Health

On any node, run:

pvecm status

Expected output:

Cluster: pi-cluster
Quorum: Yes (3 nodes)
Nodes: 3
Expected votes: 3

Also check:

pvecm nodes

Should list all three nodes with their IPs. And in the Proxmox web GUI, you should see all three nodes in the Datacenter view with green checkmarks.

If a node shows a red X or “offline” status, common ARM-specific fixes:

# Check Corosync is running
systemctl status corosync

# Verify network connectivity between nodes
ping 192.168.1.10  # from node 2
ping 192.168.1.11  # from node 1

# Check /etc/hosts has all nodes
cat /etc/hosts
# Should include:
# 192.168.1.10 pi-node1
# 192.168.1.11 pi-node2
# 192.168.1.12 pi-node3

Step 4: Create Your First LXC Container

Download the ARM64 LXC Template

Proxmox on ARM uses aarch64 container templates. From the GUI:

Go to Datacenter → Node → Local (node) → CT Templates
Click Templates
Filter by architecture: select aarch64
Download a template — Debian 12 (arm64) is recommended for broadest ARM compatibility

Or from the command line:

pveam update
pveam available --section system | grep arm64
pveam download local debian-12-arm64.tar.gz

Container Resource Limits (RAM/CPU)

Create a test container to verify everything works:

pct create 100 /var/lib/vz/template/cache/debian-12-arm64.tar.gz \
  --hostname test-container \
  --storage tank \
  --rootfs 8 \
  --cores 2 \
  --memory 1024 \
  --swap 512 \
  --net0 name=eth0,bridge=vmbr0,ip=dhcp \
  --unprivileged 1

Key ARM-specific considerations: - No KVM: Omit --ostype or set to unmanaged — there’s no KVM acceleration - Unprivileged containers: Set --unprivileged 1 — ARM security boundaries benefit from user namespace isolation - Memory limits: Be conservative — the 8GB per node is shared with Proxmox daemons, Corosync, and Ceph (if used)

Start and Test

pct start 100
pct enter 100

# Inside the container, verify architecture
uname -m     # should output: aarch64
lscpu        # shows Cortex-A76 cores

Your first ARM64 LXC container is running. Deploy a service — Pi-hole is an excellent first candidate since it has a native arm64 image:

# Inside the LXC container
apt update && apt install -y curl
curl -sSL https://install.pi-hole.net | bash

Step 5: Shared Storage with Ceph or NFS

Shared storage is what turns three independent Pi nodes into a true cluster. When storage is shared, you can migrate containers between nodes without copying data — Proxmox just reassigns the container to the new node and it picks up right where it left off.

Ceph on Raspberry Pi — Feasible?

Ceph is the gold standard for distributed storage in Proxmox clusters. But on a Pi 5, there are constraints:

Ceph Component	RAM Requirement	Pi 5 Feasibility
Ceph Monitor (MON)	1–2GB	✅ Yes — one per node
Ceph Manager (MGR)	1GB	✅ Yes — co-locate with MON
Ceph OSD (per NVMe)	2–4GB	⚠️ Tight — 4GB left for containers
Ceph Metadata Server (MDS)	1–2GB	✅ Only if using CephFS

Verdict: Ceph is viable on Pi 5 (8GB) if you limit each node to 1 OSD and keep total container count modest. With 8GB total per node: 2GB for OS + Proxmox overhead, 3GB for Ceph OSD, 3GB for containers. It works — but it’s tight.

Install Ceph via Proxmox’s built-in wizard:

# On master node
pveceph install
pveceph init --network 192.168.1.0/24

# Create MON on all three nodes
pveceph mon create pi-node1 pi-node2 pi-node3

# Create MGR on all three nodes
pveceph mgr create pi-node1 pi-node2 pi-node3

# Create OSDs from NVMe drives
pveceph osd create /dev/nvme0n1 --node pi-node1
pveceph osd create /dev/nvme0n1 --node pi-node2
pveceph osd create /dev/nvme0n1 --node pi-node3

# Create a pool
pveceph pool create container-pool --size 3 --min_size 2

The --size 3 --min_size 2 configuration means each piece of data is stored on all 3 nodes (triple replication), and writes succeed as long as 2 nodes are available. This gives you tolerance for a single node failure.

NFS Alternative for Simplicity

If Ceph’s memory requirements feel too aggressive for your workload, NFS is the pragmatic alternative:

# On Pi #1 (NFS server)
apt install nfs-kernel-server
mkdir -p /export/containers
echo "/export/containers 192.168.1.0/24(rw,sync,no_subtree_check,no_root_squash)" >> /etc/exports
systemctl restart nfs-kernel-server

# On all nodes — add as Proxmox storage
pvesm add nfs shared-nfs --server 192.168.1.10 --export /export/containers --content images,rootdir

NFS trade-off: You get shared storage with near-zero RAM overhead, but the NFS server (Pi #1) becomes a single point of failure. If Pi #1 goes down, all containers lose their storage. With Ceph, any node can fail and the cluster survives.

For more on backup and storage strategies, see our homelab backup strategy guide.

Step 6: ARM Docker Compatibility

Many homelab services run in Docker rather than LXC. Running Docker inside an LXC container on ARM64 requires understanding multi-architecture images.

Multi-Arch Images (linux/arm64)

The good news: most popular self-hosted apps now publish multi-arch Docker images. Check on Docker Hub:

# Check if an image supports ARM64
docker manifest inspect linuxserver/uptime-kuma:latest | grep architecture
# Look for "arm64" in the output

Native ARM64 images exist for:

Service	ARM64 Image	Notes
Pi-hole	`pihole/pihole:latest`	✅ Full ARM64 support
Uptime Kuma	`louislam/uptime-kuma:latest`	✅ linux/arm64
n8n	`n8nio/n8n:latest`	✅ linux/arm64
Vaultwarden	`vaultwarden/server:latest`	✅ linux/arm64
Nginx	`nginx:latest`	✅ linux/arm64
Traefik	`traefik:latest`	✅ linux/arm64/v8
Caddy	`caddy:latest`	✅ linux/arm64
Grafana	`grafana/grafana:latest`	✅ linux/arm64
Portainer	`portainer/portainer-ce:latest`	✅ linux/arm64
Ollama	`ollama/ollama:latest`	✅ ARM64 — but LLM inference is slow on Pi 5

Common Containers That Fail on ARM

Some services are x86-only. You’ll hit these walls:

Service	ARM Status	Workaround
MySQL 8	No official ARM64 image	Use MariaDB (official ARM64)
Microsoft SQL Server	x86 only	Use PostgreSQL
Plex Media Server	No ARM64 server	Use Jellyfin (native ARM64)
TeamSpeak 3 Server	x86 only	Use Mumble (ARM64)
Game servers (Minecraft, Valheim)	Mostly x86	Box64 emulation (slow but functional)

The pattern: stick to the modern, open-source alternative and you’ll almost always find ARM64 support. The proprietary and legacy tools are where x86 lock-in persists.

Building Your Own ARM Images

For custom services, use Docker Buildx to create multi-arch images:

docker buildx create --name multiarch --use
docker buildx build \
  --platform linux/arm64,linux/amd64 \
  --tag your-registry/your-image:latest \
  --push .

Or for a simple single-arch ARM64 build on the Pi itself:

docker build --platform linux/arm64 -t my-service:arm64 .

For deeper Docker networking patterns across your cluster, see our Docker networking best practices guide.

Step 7: Power and Thermal Management

Active Cooling vs. Passive

The Pi 5 under sustained load generates real heat. The official Active Cooler ($5) is non-negotiable for a cluster build:

Cooling Solution	Idle Temp	Load Temp	Throttling?	Noise
None (passive)	55°C	85°C+	✅ Yes — heavy throttle at 85°C	Silent
Official Active Cooler	38°C	58°C	❌ No	~22 dB (near-silent)
Argon THRML 40mm	35°C	52°C	❌ No	~25 dB
Ice Tower (large)	30°C	45°C	❌ No	~35 dB (audible)

The Active Cooler at 22 dB is effectively inaudible in a room with any ambient noise. It’s the sweet spot for a silent cluster.

PoE HAT Power Draw

The official PoE+ HAT adds ~2W per node. If you’re counting every watt, direct USB-C power saves 6W across three nodes. But you lose the single-cable simplicity. For most builds, the convenience tradeoff is worth 2W.

Under-Volting and CPU Governor

ARM processors benefit from conservative CPU scaling:

# Check current governor
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

# Set to ondemand (scale up only when needed)
echo "ondemand" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

# Make persistent
echo 'GOVERNOR="ondemand"' >> /etc/default/cpufrequtils

The ondemand governor keeps cores at 1.5GHz at idle and only ramps to 2.4GHz under load. This saves 2–3W per node at idle without perceptible performance impact for bursty homelab workloads.

Step 8: Troubleshooting ARM-Specific Issues

Kernel Modules Missing

Proxmox on ARM ships with a leaner kernel than x86. Some modules you’d expect may be absent:

# Check loaded modules
lsmod

# Common missing modules and fixes
# WireGuard:
apt install wireguard-tools
modprobe wireguard

# iptables/nftables (usually present but verify):
modprobe nf_tables

# USB serial (for Zigbee/Z-Wave dongles):
modprobe usbserial
modprobe ftdi_sio

Container Images Not Available for ARM

When you hit an x86-only image, you have three options:

Find an ARM64 alternative — MariaDB instead of MySQL, Jellyfin instead of Plex
Build from source on the Pi — most Go and Rust projects cross-compile trivially with GOARCH=arm64 or --target aarch64-unknown-linux-gnu
Use box64 emulation — runs x86_64 binaries on ARM64 with ~50% performance penalty. Install: apt install box64

Corosync Split-Brain on Unreliable Networks

A split-brain occurs when cluster nodes can’t communicate and each thinks it’s the sole surviving node. On a Pi cluster, this can happen if:

The PoE switch reboots (all nodes lose connectivity simultaneously)
A node’s Ethernet cable isn’t fully seated
WiFi is used instead of Ethernet (never use WiFi for Corosync)

Prevention:

# Set higher Corosync token timeout (more tolerant of brief network blips)
# Edit /etc/corosync/corosync.conf
# Increase token: 5000 → 10000

# Enable two-node mode if you ever drop to 2 nodes
pvecm expected 2

If a split-brain does occur, the recovery is:

# On the node that should rejoin
systemctl stop pve-cluster corosync
rm -rf /etc/corosync/*
# Copy corosync.conf from a healthy node
scp root@pi-node1:/etc/corosync/corosync.conf /etc/corosync/
systemctl start corosync pve-cluster

Conclusion: When to Choose ARM vs. x86

After building this cluster and running it for real workloads, the decision framework is straightforward:

Choose a Pi 5 ARM cluster when: - Power is expensive (₿0.15+/kWh) or you’re limited by circuit capacity - Noise is a hard constraint (apartment, bedroom, shared office) - You’re running 10–20 lightweight LXC containers (DNS, monitoring, automation, reverse proxy) - You want to learn clustering, distributed storage, and ARM architecture hands-on - Budget for hardware is under $300–$400

Choose x86 (used mini PC or server) when: - You need KVM virtual machines (Windows, pfSense, non-Linux OS) - Your workload is CPU-heavy (LLM inference, transcoding, databases) - You need >8GB RAM per node for a single service - You’re deploying 30+ containers and don’t want to worry about memory budgeting - Broadest Docker image compatibility matters more than power efficiency

For many homelabbers, the answer is both. An x86 Mini PC as the primary workhorse for heavy services, with a Pi 5 cluster running the always-on infrastructure layer (DNS, monitoring, ingress, automation). The Pi cluster sips power 24/7 while the x86 machine can be scheduled or powered on-demand via Wake-on-LAN.

Next Steps — Expand to 5 Nodes

The Proxmox cluster supports up to 32 nodes. For a Pi cluster, 5 nodes is the practical sweet spot — it gives you 40GB of total RAM and allows Ceph erasure coding (more space-efficient than triple replication). The same steps scale: flash Proxmox, join the cluster, add storage. Each additional node costs ~$90 (Pi 5 8GB + PoE HAT) and adds 8GB of capacity.

FAQ

Can I run VMs on a Raspberry Pi 5 Proxmox node?

No. Proxmox on ARM64 does not support KVM-based virtual machines. The Pi 5’s Cortex-A76 cores lack the hardware virtualization extensions (ARM equivalent of Intel VT-x/AMD-V) in a way that Proxmox’s QEMU-KVM stack can use. You are limited to LXC containers. If you need VMs, use an x86 Proxmox node.

Is 8GB RAM enough for Proxmox?

Yes — for LXC workloads. Proxmox itself (including Corosync and the web GUI) uses ~800MB. With 8GB, you have ~7GB for LXC containers. That fits 7–14 lightweight containers comfortably. If you add Ceph, budget another 2–3GB for the OSD daemon, leaving ~4GB for containers. The 8GB Pi 5 is the minimum viable — don’t attempt this with the 4GB model.

Can I use WiFi instead of Ethernet?

No. Never. Corosync (the cluster communication layer) requires low-latency, reliable networking. WiFi introduces variable latency, packet loss, and occasional disconnections — all of which trigger false-positive node failures and split-brain scenarios. Always use wired Ethernet for cluster nodes. If you must use WiFi for management access, add it as a secondary interface separate from the Corosync network.

What about the Pi 5 PCIe HAT for NVMe?

The Pi 5’s PCIe 2.0 x1 lane provides ~500 MB/s theoretical bandwidth — enough for a single NVMe SSD to run at near full speed (most consumer NVMe drives top out around 500–600 MB/s sequential anyway). The Pineberry Pi HatDrive! Top ($20) and Waveshare Pi 5 NVMe HAT ($15) are both well-supported. The NVMe drive must be M.2 2230 or 2242 form factor (not the longer 2280), unless you use a flexible extension cable.

How does this compare to an Orange Pi 5 Plus cluster?

The Orange Pi 5 Plus has a Rockchip RK3588 (4× Cortex-A76 + 4× Cortex-A55) with up to 16GB RAM and native M.2 NVMe slot — specs that beat the Pi 5 on paper. However, Proxmox VE does not officially support the Rockchip platform. You’d need to use Armbian as the base OS and run Docker directly or use a different orchestrator. For a pure Proxmox experience with clustering, the Pi 5 is the supported path.

Can I mix Pi 4 and Pi 5 nodes in the same cluster?

Technically yes, but not recommended. Proxmox allows heterogeneous nodes, but mixing ARM generations creates subtle problems: different kernel versions, different available kernel modules, and unpredictable migration behavior. The Pi 4’s 4GB ceiling also drags down the cluster’s useful capacity. Stick to identical Pi 5 nodes for a homogeneous, predictable cluster.

What’s the fastest way to recover a failed node?

If a Pi node fails (corrupted SD card, hardware issue), the fastest recovery is: 1. Flash a fresh Proxmox ARM64 ISO to a new microSD card 2. Boot the replacement Pi 3. Set the same static IP as the failed node 4. Join the cluster with its original node name: pvecm add <master-ip> --nodeid <original-id> 5. Re-add the NVMe drive to Ceph: pveceph osd create /dev/nvme0n1

The Ceph data on the NVMe drive (if the drive itself survived) will self-heal through replication. Total recovery time: ~15 minutes.

Do I need a UPS for a Pi cluster?

A UPS is useful but less critical than for x86 servers. The Pi 5 has no spinning disks (NVMe SSD) and handles sudden power loss more gracefully. That said, Ceph replication won’t protect you from simultaneous power loss to all 3 nodes. A small UPS like the APC Back-UPS 425VA (~$50) can keep all three Pi nodes + PoE switch running for 30–60 minutes — enough to ride out most outages.

Tailscale vs Traditional WireGuard: Which VPN Is Right for Your Homelab in 2026?

Reading time: ~11 minutes Audience: Homelab owners who need secure remote access to their services and are weighing the trade-offs between the simplicity of Tailscale and the raw performance of vanilla WireGuard

Introduction: The Remote Access Dilemma

You have spent months building your homelab. Proxmox runs your VMs, Docker Compose orchestrates your services, and Nginx Proxy Manager routes traffic on your LAN. Everything hums along beautifully — until you leave the house. Suddenly, that Nextcloud instance, your Home Assistant dashboard, and your Jellyfin media server are all unreachable. You are locked out of your own infrastructure by the simple fact that you are not on the same network.

The solution is a VPN — but which one? Two names dominate the conversation in 2026: WireGuard, the kernel-level protocol that redefined VPN performance, and Tailscale, the user-friendly mesh networking layer built on top of WireGuard. Both use the same cryptographic primitives. Both deliver excellent throughput. Yet the experience of setting them up, maintaining them, and living with them day-to-day could not be more different.

This guide compares them side-by-side for the specific use case of homelab remote access. We cover setup complexity, raw performance, NAT traversal behaviour, security models, and the scenarios where one clearly beats the other. By the end, you will know exactly which approach fits your homelab — and your tolerance for YAML files.

What Is WireGuard?

WireGuard is a Layer 3 VPN protocol designed by Jason A. Donenfeld and merged into the Linux kernel in 2020. It uses a noise-based handshake, ChaCha20 for encryption, Poly1305 for authentication, and Curve25519 for key exchange. The codebase is deliberately tiny — around 4,000 lines — making it auditable and fast.

What WireGuard does: - Creates an encrypted tunnel between two peers using public/private key pairs - Routes traffic at the IP layer with minimal overhead - Roams seamlessly between networks (Wi-Fi to cellular without dropping the tunnel)

What WireGuard does NOT do: - Manage keys (you generate, distribute, and rotate them manually) - Handle NAT traversal (if both peers are behind NAT, you need port forwarding on at least one end) - Provide a control plane or user interface - Offer access control lists or user management - Distribute configuration updates — every peer change means editing config files on every affected device

WireGuard is a protocol and a tool, not a platform. It gives you encrypted tunnels and nothing else. Everything beyond that — key distribution, topology management, DNS — is your responsibility.

Vanilla WireGuard Configuration Example

Here is a minimal WireGuard setup between a homelab server and a laptop:

Server (/etc/wireguard/wg0.conf):

[Interface]
PrivateKey = <server-private-key>
Address = 10.0.0.1/24
ListenPort = 51820
# Forward traffic from VPN clients to LAN
PostUp = iptables -A FORWARD -i wg0 -j ACCEPT
PostUp = iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -D FORWARD -i wg0 -j ACCEPT
PostDown = iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE

[Peer]
# Laptop
PublicKey = <laptop-public-key>
AllowedIPs = 10.0.0.2/32

Laptop (/etc/wireguard/wg0.conf):

[Interface]
PrivateKey = <laptop-private-key>
Address = 10.0.0.2/24
DNS = 192.168.1.1  # Your homelab DNS

[Peer]
# Homelab server
PublicKey = <server-public-key>
Endpoint = your-home-public-ip:51820
AllowedIPs = 10.0.0.0/24, 192.168.1.0/24
PersistentKeepalive = 25

Every new device requires generating a key pair, adding a [Peer] block to the server config, and reloading WireGuard. For three devices, this is manageable. For ten, it becomes a chore. For a family of four with laptops, phones, and tablets, it is a part-time job.

What Is Tailscale?

Tailscale is a mesh VPN built on top of WireGuard. It uses WireGuard for the data plane — every packet between your devices is encrypted with the same WireGuard primitives — but wraps it with a coordination server that handles key exchange, NAT traversal, and access control automatically.

Here is what Tailscale adds on top of WireGuard:

Automatic key exchange. You sign in with Google, GitHub, Microsoft, or an OIDC provider. Tailscale’s coordination server generates WireGuard key pairs, distributes them, and rotates them — you never touch a private key.
NAT traversal that actually works. Tailscale uses DERP (Designated Encrypted Relay for Packets) relays when direct connections are impossible, and aggressively probes for direct paths using NAT-PMP, UPnP, and STUN. In practice, it establishes direct peer-to-peer connections far more often than you would expect — even through double NAT.
MagicDNS. Every device gets a stable <hostname>.ts-net.ts.net hostname that resolves from any other device on your tailnet. No DNS configuration, no /etc/hosts entries.
Built-in ACLs. Define who can access what using a JSON or HuJSON policy file. Tags let you group devices (e.g., tag:production, tag:iot) and write rules like “devices tagged iot can only reach port 80 on the monitoring server.”
Exit nodes. Any device can be promoted to an exit node with one flag: tailscale up --advertise-exit-node. All your traffic routes through your homelab as if you were sitting at home.
Tailscale Funnel. Expose a specific port to the public internet through Tailscale’s ingress, no port forwarding required. Useful for sharing a single service without exposing your entire tailnet.

Tailscale Setup in Practice

On your homelab server:

# Install
curl -fsSL https://tailscale.com/install.sh | sh

# Authenticate and join your tailnet
sudo tailscale up --advertise-routes=192.168.1.0/24 --advertise-exit-node

On your laptop:

curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up

That is it. Both devices are now connected. The laptop can reach the server at <server-hostname>.ts-net.ts.net. Routes to the homelab LAN are automatically available. No key generation. No [Peer] blocks. No PostUp iptables rules. The whole process takes under two minutes.

Deep Dive: Setup Complexity

The difference in setup philosophy is best illustrated by what happens when you add a fifth device to your network.

With WireGuard, adding device #5 means: 1. Generate a key pair on the new device (wg genkey | tee privatekey | wg pubkey) 2. Copy the public key 3. SSH into every existing peer that needs to communicate with the new device 4. Add a [Peer] block to each config file 5. Run wg syncconf wg0 <(wg-quick strip wg0) on each peer or restart the interface 6. Update your mental map of which IP belongs to which device 7. If you are running a hub-and-spoke topology, Steps 3–5 only apply to the hub. If you want a full mesh, apply to every peer.

With Tailscale, adding device #5 means: 1. Install Tailscale 2. Run tailscale up 3. Authenticate (OAuth or pre-auth key) 4. Done — the device appears in your admin console, gets a MagicDNS name, and can reach every other device automatically.

The gap widens with every additional device. WireGuard’s manual key management is fundamentally an O(n²) problem for a full mesh — every new peer requires updates to every existing peer. Tailscale makes it O(1). This alone is the deciding factor for many homelabbers.

Deep Dive: Performance and Latency

WireGuard’s performance advantage is real, but the size of the gap depends on how you run Tailscale.

Kernel WireGuard (vanilla) operates entirely in kernel space. Packets are encrypted and decrypted without context-switching to userspace. On a modern x86 server, WireGuard saturates a gigabit link with negligible CPU usage. Latency overhead is typically under 1 millisecond.

Tailscale runs WireGuard in userspace (via the wireguard-go implementation on most platforms) because the coordination layer needs to manage keys and routing dynamically. This adds a measurable but typically irrelevant overhead:

Throughput: 5–10% lower than kernel WireGuard on the same hardware. On a 1 Gbps link, that is the difference between 940 Mbps and 850–890 Mbps — significant for a datacenter, irrelevant for a homelab where your upstream is likely 20–100 Mbps.
Latency: 1–3 ms additional overhead vs kernel WireGuard. Again, meaningful for high-frequency trading, invisible for SSH sessions and Jellyfin streaming.

The DERP relay factor: When Tailscale cannot establish a direct peer-to-peer connection (rare, but possible with very restrictive NAT), traffic routes through Tailscale’s DERP relay servers. These are geographically distributed, but relayed traffic adds 20–80 ms of latency depending on relay proximity. Vanilla WireGuard has no equivalent fallback — if a direct connection cannot be established, you simply have no connectivity. In practice, this makes Tailscale more reliable for homelabbers on residential ISPs with CGNAT, even if it is sometimes slightly slower.

Verdict: If you need every last megabit of throughput and you control both ends of the connection (e.g., a site-to-site link between two data centers), use kernel WireGuard. For homelab remote access — where your bottleneck is almost certainly your ISP uplink, not the VPN — Tailscale’s overhead is invisible.

Deep Dive: NAT Traversal

NAT traversal is where Tailscale earns its keep and vanilla WireGuard leaves you on your own.

WireGuard’s NAT behaviour: - WireGuard is UDP-based and NAT-unfriendly by design. It does not attempt STUN, UPnP, or NAT-PMP. - If one peer has a public IP and an open port, the other peer behind NAT can initiate a connection and WireGuard will work — the NAT’d peer’s UDP “connection” is tracked by the NAT gateway as long as PersistentKeepalive keeps it alive. - If both peers are behind NAT (double NAT, CGNAT), WireGuard cannot establish a direct connection without manual port forwarding on at least one end. This is the reality for many homelabbers on residential ISPs.

Tailscale’s NAT behaviour: - Tailscale aggressively probes for direct connections using STUN, NAT-PMP, and UPnP. - If direct connectivity is impossible, traffic falls back to DERP relays — encrypted TCP tunnels through Tailscale’s infrastructure. Your packets are end-to-end encrypted (Tailscale cannot read them), but they do transit Tailscale’s servers. - In the Tailscale admin console, you can see exactly which path each peer connection takes: direct, or via a specific DERP relay. - If you are uncomfortable with DERP relays, you can run your own DERP server in your homelab. Tailscale publishes the open-source derper binary.

For a homelabber behind CGNAT who wants to access services from a coffee shop (also behind NAT), Tailscale is the only approach that works out of the box. WireGuard requires either a public relay server (a $5 VPS) or port forwarding that your ISP may not offer.

Deep Dive: Security Model

Both systems use WireGuard’s cryptography. The difference is in the control plane.

Vanilla WireGuard — Decentralized Trust: - Every peer’s public key is manually distributed. You control which keys are trusted. - There is no central authority that can add or remove peers. Compromising one peer does not give an attacker the ability to add new peers to the network. - The downside: key rotation requires manual coordination. If a device is lost or stolen, you must remove its public key from every peer’s config before the thief can connect.

Tailscale — Centralized Trust with Guardrails: - Tailscale’s coordination server is the central authority. It holds every device’s WireGuard private key (encrypted at rest) and distributes them to peers. - If an attacker compromises your Tailscale account (via SSO), they can add devices to your tailnet. This is the centralization risk. - Tailscale mitigates this with: mandatory device approval (new devices must be approved in the admin console), ACLs that limit what each device can access, and the ability to disable a device remotely with one click. - For the truly paranoid: Headscale is an open-source reimplementation of the Tailscale coordination server that you self-host. It gives you the Tailscale experience (automatic key management, MagicDNS, ACLs) with zero dependency on Tailscale’s infrastructure.

The pragmatic take: For a homelab, Tailscale’s centralized model is arguably more secure in practice because it makes security easy. ACLs that take five minutes to write in Tailscale would require a complex iptables ruleset in vanilla WireGuard — and most homelabbers never get around to writing them. The best security model is the one you actually configure correctly.

When to Choose Vanilla WireGuard

WireGuard is the right choice when:

You have a small, static peer count. Three or four devices that rarely change. The manual key management overhead is tolerable.
Performance is paramount. You are running a site-to-site tunnel between two servers and want kernel-level throughput with zero userspace overhead.
You need air-gapped operation. No internet dependency for coordination. WireGuard works on a completely isolated network — no coordination server, no SSO, no cloud dependency.
You want zero external dependencies. WireGuard is in the Linux kernel. No third-party service, no subscription, no API calls. It keeps working as long as the kernel boots.
You run a management UI. Tools like WG-Easy or WireGuard-UI provide a web dashboard for key management, QR code generation, and peer configuration — bridging the gap between vanilla WireGuard and a full platform like Tailscale without the cloud dependency. We cover WireGuard-UI in our Nginx Proxy Manager Docker Compose Guide.

When to Choose Tailscale

Tailscale wins when:

You have multiple devices and non-technical users. If your spouse, kids, or parents need access to homelab services, Tailscale’s sign-in flow eliminates the support burden. No private keys to email, no QR codes to scan, no config files to edit.
You are behind CGNAT or restrictive NAT. Tailscale’s NAT traversal and DERP fallback make it work in network environments where vanilla WireGuard simply cannot establish a connection.
You add and remove services frequently. Tailscale’s ACLs and tags let you segment access without touching device configs. Adding a new service that should only be reachable by certain devices is a policy edit, not a per-device reconfiguration.
You want MagicDNS. Typing ssh proxmox.ts-net.ts.net instead of remembering 10.0.0.5 is a quality-of-life improvement that compounds daily.
You want built-in sharing. Tailscale Funnel lets you share a single service publicly without exposing your entire tailnet — useful for sharing a Jellyfin stream with a friend without giving them VPN access.

For a deeper dive into exposing homelab services securely, see our Cloudflare Tunnel Homelab Guide and the comparison between automation approaches in DockFlare vs Manual Cloudflare Tunnels.

The Hybrid Approach: Tailscale with Headscale

There is a third option that combines the best of both worlds: Headscale, an open-source reimplementation of the Tailscale control server.

With Headscale, you: - Run the coordination server yourself — no dependency on Tailscale’s infrastructure - Keep automatic key management, MagicDNS, and ACLs - Use the standard Tailscale clients (tailscale up --login-server https://headscale.yourdomain.com) - Pay nothing — Headscale is Apache 2.0 licensed - Control every aspect of your tailnet from a self-hosted dashboard

Headscale requires a server (a $5 VPS or a Proxmox LXC works perfectly) and about an hour of setup. It is the answer for homelabbers who want Tailscale’s user experience but refuse to depend on a cloud service for their VPN coordination. For related self-hosting infrastructure patterns, see our Docker Networking Best Practices guide.

2026 Verdict: Which Should You Use?

The answer depends on a single question: how many devices and who manages them?

Scenario	Recommendation
Solo homelab, 2–3 devices, static setup, you enjoy Linux networking	WireGuard with WG-Easy
Solo homelab, 5+ devices, dynamic, behind CGNAT	Tailscale (free tier)
Family homelab, non-technical users, multiple device types	Tailscale (free tier handles 3 users)
Privacy absolutist, want zero cloud dependency	Headscale (self-hosted Tailscale)
Site-to-site link between two servers	Kernel WireGuard
Homelab + frequent service sharing with friends	Tailscale with Funnel

My recommendation for most homelabbers in 2026: Start with Tailscale’s free tier. It takes five minutes, works through any NAT, and costs nothing for up to three users and 100 devices — which covers the vast majority of homelab setups. If you later outgrow the free tier or want to eliminate the cloud dependency, migrate to Headscale. Your devices will not notice the difference.

FAQ: Tailscale vs WireGuard for Homelab

1. Is Tailscale free for homelab use?

Yes. Tailscale’s free tier includes up to 3 users and 100 devices, which covers virtually every homelab. The free tier includes MagicDNS, ACLs, exit nodes, and DERP relays. The only limitations are user count and administrative features like device approval policies and custom OIDC.

2. Does Tailscale slow down my connection?

Minimally. Tailscale uses userspace WireGuard (wireguard-go) which adds 5–10% overhead compared to kernel WireGuard on the same hardware. For a typical homelab internet connection (20–100 Mbps upstream), this overhead is invisible. The bottleneck is your ISP, not Tailscale. Latency overhead is 1–3 ms for direct connections, higher only when traffic routes through DERP relays.

3. Can I use Tailscale without their coordination server?

Yes — that is exactly what Headscale does. Headscale is an open-source reimplementation of Tailscale’s control server. You self-host it and point your Tailscale clients at your own server with tailscale up --login-server https://headscale.yourdomain.com. The Tailscale clients are open source and support alternative coordination servers natively.

4. What happens if Tailscale’s servers go down?

Existing peer-to-peer connections continue working — the data plane is WireGuard, and WireGuard tunnels survive coordination server outages. You cannot add new devices, rotate keys, or fetch ACL updates until the server recovers. If this risk is unacceptable, run Headscale on your own infrastructure.

5. Can I run both WireGuard and Tailscale on the same machine?

Technically yes — they use different interfaces (wg0 vs tailscale0). But routing conflicts are likely if both try to manage the same subnets. Choose one as your primary VPN. If you need both (e.g., WireGuard for a site-to-site link and Tailscale for client access), assign them non-overlapping IP ranges.

6. How does Tailscale handle my homelab DNS?

Tailscale’s MagicDNS assigns every device a stable <hostname>.ts-net.ts.net name. If you enable “Override local DNS” in the Tailscale admin console, you can also point *.ts-net.ts.net queries at your homelab DNS server (e.g., Pi-hole or AdGuard Home). Combined with subnet routing, this lets you resolve LAN hostnames from anywhere.

7. Is WireGuard more secure than Tailscale since there is no third party?

WireGuard has a smaller trust boundary — no coordination server means one fewer thing to compromise. But Tailscale’s end-to-end encryption means the coordination server never sees your traffic. The risk is account compromise (attacker adds a device to your tailnet), which Tailscale mitigates with device approval, ACLs, and MFA on your SSO provider. For most users, the practical security of Tailscale’s ACLs (which people actually configure) outweighs the theoretical security of WireGuard’s minimalism (where iptables rules often go unwritten).

8. What about Tailscale Funnel vs Cloudflare Tunnel?

Both expose services to the public internet without port forwarding. Tailscale Funnel is simpler (one command: tailscale funnel 8080) but routes through Tailscale’s ingress servers and has bandwidth limits. Cloudflare Tunnel is more feature-rich (WAF, caching, custom domains) and has no bandwidth limits on the free tier. For robust public exposure, Cloudflare Tunnel wins. For quick, temporary sharing, Tailscale Funnel is more convenient. See our Cloudflare Tunnel Homelab Guide for a full comparison.

9. Can I run Tailscale on a Raspberry Pi?

Yes. Tailscale provides ARM and ARM64 binaries. A Raspberry Pi 4 or 5 running as a subnet router and exit node is a common homelab pattern — it uses under 5W and gives you remote access to your entire LAN without running a full server. See our Raspberry Pi 5 Proxmox Cluster guide for ARM homelab ideas.

10. How do I secure WireGuard if I choose the vanilla route?

Use wg-quick for interface management, enable the firewall with iptables rules that only allow WireGuard traffic on the listening port, use PersistentKeepalive = 25 for NAT’d peers, and rotate keys every 90 days. Consider running WG-Easy for a web-based management interface. Most importantly: document which public key belongs to which device — you will thank yourself when you need to revoke access six months from now.

DockFlare vs Manual Cloudflare Tunnels: Automate Your Homelab Ingress with Docker Labels (2026)

Reading time: ~12 minutes Audience: Homelab owners running Docker who use (or plan to use) Cloudflare Tunnel and want to stop manually editing YAML files every time they spin up a new service

Introduction: The Tunnel Configuration Bottleneck

Cloudflare Tunnel is one of the most transformative tools in the homelab ecosystem. It eliminates port forwarding, defeats CGNAT, and wraps every service in free SSL — all without exposing your home IP address. We covered the full setup in our Cloudflare Tunnel Homelab Guide, and thousands of homelabbers have since adopted it as their primary ingress solution.

But there is a problem that emerges about three weeks in. You have tunneled your first service — say, Home Assistant. Then you add Jellyfin. Then Immich. Then Uptime Kuma. Each new service means opening your config.yml, adding an ingress block with the correct hostname and service URL, and restarting cloudflared. Your YAML file grows. Your memory of which services are tunneled grows stale. Configuration drift sets in: you decommissioned that Plex container two months ago, but its tunnel rule is still sitting there, pointing at nothing.

This is the problem that DockFlare solves. Instead of maintaining tunnel configuration in a separate YAML file, DockFlare reads Docker labels directly from your containers and synchronizes them with Cloudflare’s API automatically. You define ingress rules where the service lives — in your Docker Compose file — and DockFlare handles the rest.

In this guide, we compare both approaches head-to-head with real Docker Compose examples, a decision framework based on your homelab’s scale, and the trade-offs you need to understand before migrating.

What Is DockFlare?

DockFlare is an open-source Docker container that acts as a bridge between your Docker host and the Cloudflare API. It watches Docker events in real time and translates container labels into Cloudflare Tunnel ingress rules.

Here is what it does under the hood:

You deploy DockFlare alongside your other containers, mounting the Docker socket.
You add labels like dockflare.domain=app.yourdomain.com and dockflare.port=8080 to any service you want to expose.
DockFlare detects the label, authenticates to the Cloudflare API using a tunnel token, and creates or updates the ingress rule.
When you stop the container, DockFlare removes the rule. No orphaned tunnel entries.

The mental model shift is significant: instead of managing tunnels in a separate configuration file that lives outside your service definition, you manage ingress at the service level. The Docker Compose file that defines your application also defines how the outside world reaches it.

Comparison Matrix: DockFlare vs Manual Cloudflare Tunnel

Aspect	Manual Cloudflare Tunnel (`cloudflared`)	DockFlare
Configuration location	`~/.cloudflared/config.yml` (separate file)	Docker labels inside each service’s `docker-compose.yml`
Adding a new service	Edit YAML → add `ingress` block → restart `cloudflared` container	Add 2 Docker labels → `docker compose up -d` → done
Removing a service	Edit YAML → remove `ingress` block → restart `cloudflared` container	`docker compose down` → DockFlare removes rule automatically
Configuration drift risk	High — manual sync required between running containers and tunnel config	None — labels are the source of truth, auto-synced
Learning curve	Low — one config file, well-documented	Moderate — must understand Docker labels and DockFlare’s label schema
Multi-host support	Deploy `cloudflared` on each host, manage per-host configs	One DockFlare per Docker host (or use Docker Swarm mode)
Dependency	Only `cloudflared` binary	Docker socket + Cloudflare API access + DockFlare container
Failure mode	Tunnel config stays static; services become unreachable if IPs change	If DockFlare goes down, existing tunnels persist; new services won’t be tunneled until it recovers
GUI management	Cloudflare Zero Trust dashboard (manual click-based)	None — fully label-driven (infrastructure-as-code)
Best for	1–5 services, static homelab, users who prefer explicit control	6+ services, frequent additions/removals, Docker Compose-first workflows

Approach 1: Manual Cloudflare Tunnel with `cloudflared`

This is the traditional approach. You deploy the cloudflared container, mount a persistent config directory, and define every ingress rule by hand.

Docker Compose

# docker-compose.yml — manual cloudflared
version: "3.8"
services:
  cloudflared:
    image: cloudflare/cloudflared:latest
    container_name: cloudflared
    restart: unless-stopped
    command: tunnel run
    environment:
      - TUNNEL_TOKEN=${CLOUDFLARE_TUNNEL_TOKEN}
    volumes:
      - ./cloudflared-config:/home/nonroot/.cloudflared
    networks:
      - proxy

Config File (`config.yml`)

# ./cloudflared-config/config.yml
tunnel: YOUR_TUNNEL_ID
credentials-file: /home/nonroot/.cloudflared/YOUR_TUNNEL_ID.json

ingress:
  # Home Assistant
  - hostname: ha.yourdomain.com
    service: http://homeassistant:8123
  # Jellyfin
  - hostname: media.yourdomain.com
    service: http://jellyfin:8096
  # Uptime Kuma
  - hostname: status.yourdomain.com
    service: http://uptime-kuma:3001
  # Immich
  - hostname: photos.yourdomain.com
    service: http://immich-server:3000
  # Catch-all: 404 for unmatched hostnames
  - service: http_status:404

Adding a New Service (Manual Workflow)

# 1. Edit config.yml and add a new ingress block
vim ./cloudflared-config/config.yml

# 2. Restart cloudflared to pick up the change
docker restart cloudflared

# 3. Verify the tunnel is healthy
docker logs cloudflared --tail 20

This workflow works. It is battle-tested and thoroughly documented. But at 5 services, the config file is manageable. At 15 services — with some pointing at containers that were renamed, moved to a different Docker network, or decommissioned entirely — it becomes a liability.

Approach 2: DockFlare — Label-Driven Tunnel Automation

DockFlare replaces the manual config.yml with Docker labels. You deploy DockFlare once, then add labels to any service you want to expose.

DockFlare Docker Compose

# dockflare-stack.yml
version: "3.8"
services:
  dockflare:
    image: ghcr.io/truecharts/dockflare:latest
    container_name: dockflare
    restart: unless-stopped
    environment:
      - CLOUDFLARE_TUNNEL_TOKEN=${CLOUDFLARE_TUNNEL_TOKEN}
      - DOCKFLARE_WATCH_INTERVAL=30
      - DOCKFLARE_LOG_LEVEL=info
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
    networks:
      - proxy

networks:
  proxy:
    external: true

Service with DockFlare Labels

# Example service — Home Assistant with DockFlare labels
services:
  homeassistant:
    image: ghcr.io/home-assistant/home-assistant:stable
    container_name: homeassistant
    restart: unless-stopped
    volumes:
      - ./ha-config:/config
    environment:
      - TZ=Asia/Jakarta
    networks:
      - proxy
    labels:
      - "dockflare.domain=ha.yourdomain.com"
      - "dockflare.port=8123"
      - "dockflare.protocol=http"

That is the entire workflow. Add the labels, run docker compose up -d, and DockFlare detects the new container within its watch interval (30 seconds by default). The ingress rule appears in your Cloudflare Zero Trust dashboard and traffic starts flowing.

Removing a Service

docker compose down
# DockFlare detects the container stopped and removes the ingress rule automatically.
# No config file cleanup. No restart needed.

Decision Framework: Which One Should You Use?

Answer these questions to determine which approach fits your homelab:

How many services do you expose through Cloudflare Tunnel? If the answer is 5 or fewer, manual cloudflared configuration is simple enough that DockFlare’s additional complexity may not be worth it. At 6+ services, the automation benefit compounds with every new container.
How often do you add or remove services? If your homelab is static — the same ten services running for months — manual config works fine. If you experiment frequently, spin up temporary services, or run a CI/CD pipeline that deploys containers, DockFlare’s automatic cleanup prevents configuration rot.
Do you already manage everything through Docker Compose? DockFlare fits naturally into a Compose-first workflow where every aspect of a service — ports, volumes, networks, and now ingress — lives in one file. If you use Portainer or a GUI to manage containers, DockFlare’s label approach still works but requires accessing the label editor for each container.
Do you need multi-host tunnel support? DockFlare runs per-Docker-host. If you have three Proxmox nodes each running Docker, you need three DockFlare instances (or one if you use Docker Swarm and constrain it to a manager node). Manual cloudflared per host is equally straightforward in this scenario.
How comfortable are you with Docker labels? DockFlare adds a dependency on label-based configuration. If Docker labels are already part of your workflow (for Traefik routing, for example), DockFlare slots in naturally. If you have never touched a Docker label, there is a small learning curve.

Common Pitfalls and Solutions

Pitfall 1: DockFlare Cannot Reach the Cloudflare API

Symptom: DockFlare starts but no ingress rules appear. Logs show 401 Unauthorized or connection refused.

Fix: Verify your tunnel token has the correct permissions. The token must be scoped to the specific tunnel, not the account-wide API token. Generate it from Cloudflare Zero Trust → Networks → Tunnels → [Your Tunnel] → Configure → Credentials. Do not reuse the Global API Key — it has more permissions than DockFlare needs and is a security risk if the environment variable leaks.

Pitfall 2: Container on Wrong Docker Network

Symptom: DockFlare creates the ingress rule, but traffic returns 502 Bad Gateway.

Fix: DockFlare routes traffic using Docker’s internal DNS. The target container must be on the same Docker network as DockFlare, or on a network that DockFlare can reach. The simplest setup: create a dedicated proxy network and attach both DockFlare and every tunneled service to it.

docker network create proxy

Then add networks: - proxy to both DockFlare and every service with dockflare.* labels.

Pitfall 3: Stale Ingress Rules After Container Removal

Symptom: You stopped a container, but its ingress rule is still in Cloudflare Zero Trust. DockFlare did not clean it up.

Fix: DockFlare cleans up rules for containers that are stopped or removed, not containers that are simply unreachable. If you removed the container outside of Docker Compose (e.g., docker rm without docker compose down), DockFlare may not detect the removal event. Use docker compose down for proper lifecycle management. If you still have orphaned rules, remove them manually from the Cloudflare dashboard — DockFlare will not overwrite rules it did not create.

Pitfall 4: Token Exposure in Plain-Text Compose Files

Symptom: You committed your docker-compose.yml to a Git repository with the tunnel token hardcoded.

Fix: Never hardcode secrets. Use an .env file:

# .env (gitignored)
CLOUDFLARE_TUNNEL_TOKEN=eyJ...your-token-here

# docker-compose.yml (safe to commit)
environment:
  - CLOUDFLARE_TUNNEL_TOKEN=${CLOUDFLARE_TUNNEL_TOKEN}

Add .env to your .gitignore. For additional security, consider Docker secrets if you run Docker Swarm, or HashiCorp Vault if you already have it in your stack (see our self-hosted password manager comparison for a lighter-weight secrets management approach).

Integration with Reverse Proxies

DockFlare and manual Cloudflare Tunnels both work alongside reverse proxies. The pattern depends on your architecture:

Architecture	How It Works	Best For
Tunnel → Service (Direct)	Cloudflare Tunnel points directly at each container’s port. No reverse proxy involved.	Fewer than 5 services, simple setups
Tunnel → Nginx Proxy Manager → Services	Tunnel points at NPM on port 80/443. NPM routes by hostname to backend containers.	Users who want a GUI for proxy host management
Tunnel → Traefik → Services	Tunnel points at Traefik. Traefik uses Docker labels to route to backends.	Docker-native, label-driven workflows — pairs naturally with DockFlare

The Tunnel → NPM → Services pattern is the most popular in the WordForge community. Cloudflare Tunnel provides the secure ingress from the internet. Nginx Proxy Manager handles SSL termination (though it is technically double-encrypted — Cloudflare edge + NPM), hostname routing, and access lists. Each backend container only needs to be on the Docker network, with no port exposure to the host.

For a full walkthrough of this pattern, see our Cloudflare Tunnel Homelab Guide and Nginx Proxy Manager Docker Compose articles.

Already running Traefik? Our reverse proxy comparison guide includes a section on Traefik + Cloudflare Tunnel integration with middleware chains.

Security Considerations

Whether you use DockFlare or manual cloudflared, the security model is the same: Cloudflare sits between the internet and your homelab, and the tunnel is an outbound-only encrypted connection. Neither approach opens ports on your router. Both benefit from Cloudflare’s DDoS protection at the free tier.

However, DockFlare introduces a new attack surface: the Docker socket. Mounting /var/run/docker.sock into any container gives that container root-equivalent access to your Docker host. DockFlare needs read-only access (:ro) to list containers and read labels. It does not need write access.

Mitigations:

Always mount the Docker socket as read-only: - /var/run/docker.sock:/var/run/docker.sock:ro
Use a dedicated tunnel token scoped only to the specific tunnel, not an account-wide API token.
Monitor DockFlare logs for unexpected API calls. DockFlare should only call Cloudflare’s tunnel ingress API.
Keep DockFlare updated. Subscribe to the DockFlare GitHub releases for security patches.
Consider docker-socket-proxy as an alternative to direct socket mounting. It exposes a filtered subset of the Docker API over HTTP, limiting what DockFlare can do. This adds complexity but reduces the blast radius of a compromised container.

FAQ

Does DockFlare replace `cloudflared` entirely?

No — DockFlare manages tunnel ingress rules (which hostname routes to which service). The actual tunnel connection between your homelab and Cloudflare’s edge is still handled by Cloudflare’s infrastructure. DockFlare communicates with the Cloudflare API to update the ingress configuration. You do not need to run a separate cloudflared container alongside DockFlare — DockFlare handles the API-side management.

Can I use both DockFlare and manual `cloudflared` at the same time?

Technically yes, but it creates confusion about which system owns which ingress rules. DockFlare only manages rules for containers with dockflare.* labels. Rules defined manually in config.yml are invisible to DockFlare and vice versa. If you are migrating from manual to DockFlare, run DockFlare alongside your existing setup for a week, then decommission the manual cloudflared container once you have verified all services are reachable through DockFlare-managed rules.

What happens if DockFlare crashes?

Your tunnel remains operational. Cloudflare Tunnel ingress rules are stored on Cloudflare’s side, not inside DockFlare. If DockFlare goes down, existing tunnels continue routing traffic. You only lose the ability to add or remove ingress rules until DockFlare recovers. This is a graceful degradation — your services stay online.

Does DockFlare support multiple tunnels?

Yes — you can run multiple DockFlare instances with different tunnel tokens. This is useful if you want to segregate services across different Cloudflare tunnels (e.g., one tunnel for public-facing services, another for admin-only dashboards). Each instance watches all containers on the host but only manages rules for containers whose labels match its configured tunnel.

How does DockFlare compare to Traefik’s Cloudflare integration?

They solve different problems. Traefik is a reverse proxy — it terminates HTTP connections and routes them to backends. DockFlare manages Cloudflare Tunnel ingress rules — it tells Cloudflare “send traffic for app.example.com to this internal service.” If you use Traefik, your tunnel points at Traefik, and Traefik routes to backends. If you use DockFlare without a reverse proxy, the tunnel points directly at each container. The two tools can coexist: DockFlare creates the tunnel ingress rule pointing at Traefik, and Traefik handles internal routing.

The Bottom Line

Manual Cloudflare Tunnel configuration with cloudflared is the right choice for homelabs with 1–5 static services. It is simpler, has fewer moving parts, and the Cloudflare documentation covers every edge case. You edit one YAML file, restart one container, and you are done.

DockFlare becomes the better choice once your homelab crosses the ~6-service threshold, or if you add and remove services frequently. The label-based approach eliminates configuration drift — your Docker Compose files become the single source of truth for both service definition and ingress rules. Services that are removed clean up after themselves. Services that are added come online without touching a separate config file.

Both approaches give you the same end result: secure, SSL-protected access to your self-hosted services from anywhere in the world, without opening a single port on your router. Pick the one that matches your homelab’s complexity.

The 2026 Homelab Automation Stack: n8n, Self-Hosted LLMs, and Intelligent Monitoring

2026-06-11T00:00:00+07:00

The 2026 Homelab Automation Stack: Moving Beyond Simple Containers

Reading time: ~18 minutes Audience: Homelab owners running 10+ containers who want their infrastructure to respond to events automatically — with AI-powered intelligence, not just cron jobs

Introduction: Why “Set and Forget” Is No Longer Enough

You deployed your first Docker container. Then ten more. You added Proxmox as your hypervisor, Nginx Proxy Manager for reverse proxy, and a handful of monitoring dashboards. Everything works — until it doesn’t. A disk fills up at 3 AM. A container crashes silently. A certificate expires. You discover these things when something breaks, not before.

The 2026 homelab has outgrown passive monitoring. Running a modern self-hosted stack means dozens of interconnected services, each with its own failure modes, update cadences, and resource requirements. Manual intervention doesn’t scale. What scales is event-driven automation — a system that detects anomalies, reasons about them, and acts without you reaching for an SSH client.

This guide assembles the three components that make that possible: n8n for workflow orchestration, Ollama for local AI intelligence, and Uptime Kuma for event-driven observability. Together they form a stack that watches your infrastructure, thinks about what it sees, and fixes what it can.

The 2026 Standard: Agentic Infrastructure

The term “agentic” has become shorthand for systems that don’t just report problems — they respond to them. In the homelab context, this means:

Capability	Pre-2026 Approach	2026 Automation Stack
Monitoring	Dashboard you check manually	Webhooks that trigger workflows
Alerting	“Service X is down” email	AI-summarized alerts with probable cause
Remediation	SSH in and restart manually	n8n detects failure → restarts container → confirms recovery
Log analysis	grep through files when something breaks	Ollama summarizes anomaly patterns from log streams
Certificate renewal	Cron job with email on failure	n8n tracks expiry → triggers renewal → verifies → alerts only on failure

This isn’t science fiction. Every piece is available today as open-source, self-hosted software — and this guide shows you how to wire them together.

What Defines a 2026 Automation Stack?

From Static Containers to Event-Driven Systems

A traditional homelab runs containers defined in a docker-compose.yml file. They start, they serve, they (hopefully) stay running. This is static infrastructure — it does what you told it to do when you ran docker compose up -d, and nothing more.

An event-driven system adds a layer that says: when X happens, do Y. X could be a service going down, a disk hitting 90% utilization, a new CVE being published for one of your containers, or a backup job completing. Y could be sending a notification, restarting a container, running a cleanup script, or asking an LLM to summarize a log dump and suggest next steps.

The key architectural shift: your automation stack becomes a peer to your application stack, not a bolt-on. It gets its own Docker network, its own resource budget, and its own persistence.

The Three Pillars: Orchestration, Intelligence, Observability

Pillar	Tool	Role	Without It
Orchestration	n8n	Connects services, runs workflows, makes decisions	Manual intervention for every incident
Intelligence	Ollama	Summarizes, classifies, recommends	Alerts are raw data dumps
Observability	Uptime Kuma	Detects state changes, fires webhooks	You don’t know something broke until you check

Each pillar feeds the others: Uptime Kuma detects a service outage → fires a webhook to n8n → n8n queries Ollama for log analysis → n8n sends a contextual alert to Discord or Matrix. When it works, you receive a message that says: “Jellyfin is down. Probable cause: transcode directory full (97%). Action taken: cleared transcode cache, restarted container. Confirmed healthy.”

Pillar 1: Workflow Orchestration with n8n

Why n8n Beats Zapier and Make for Homelabs

n8n is a fair-code workflow automation platform that you self-host. It connects to hundreds of services through native nodes, supports custom JavaScript and Python execution, and runs entirely on your hardware. For homelab use, three factors make it the clear choice over cloud alternatives:

Feature	n8n (Self-Hosted)	Zapier	Make (Integromat)
Data residency	Your server	Zapier’s cloud	Make’s cloud
Cost	Free (unlimited workflows)	$30+/mo for multi-step	$9+/mo with operation limits
API call limits	Only limited by your hardware	Tiered by plan	1,000–10,000 ops/mo
Community nodes	400+ npm packages	Limited built-in	Limited built-in
Custom code	JavaScript + Python nodes	Limited JS	Limited
SSH/on-prem connections	Native (runs on your LAN)	None	None
Offline operation	Fully functional	No	No

The on-prem nature is the killer feature for homelabs. n8n can reach services on 192.168.x.x addresses, talk to your Proxmox API, SSH into LXC containers, and read local files — none of which a cloud automation tool can do without exposing your network.

Docker Compose Setup for n8n

Create a dedicated directory for your automation stack and deploy n8n with PostgreSQL (recommended for production use) and Redis (for queue mode and performance):

# docker-compose.yml — n8n Automation Core
version: '3.8'

services:
  # PostgreSQL — n8n's database for workflow storage and execution state
  # Without this, n8n uses SQLite which is fine for testing but
  # chokes on concurrent workflow executions
  postgres:
    image: postgres:16-alpine
    container_name: n8n-postgres
    restart: unless-stopped
    environment:
      - POSTGRES_USER=${POSTGRES_USER:-n8n}
      - POSTGRES_PASSWORD=${POSTGRES_PASSWORD}
      - POSTGRES_DB=${POSTGRES_DB:-n8n}
    volumes:
      - ./postgres-data:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U n8n"]
      interval: 10s
      timeout: 5s
      retries: 5
    networks:
      - automation-net

  # Redis — enables queue mode for n8n
  # Without Redis, n8n processes workflows in-process. With Redis,
  # you get separate workers, retry queues, and better concurrency
  redis:
    image: redis:7-alpine
    container_name: n8n-redis
    restart: unless-stopped
    command: redis-server --appendonly yes
    volumes:
      - ./redis-data:/data
    healthcheck:
      test: ["CMD", "redis-cli", "ping"]
      interval: 10s
      timeout: 5s
      retries: 5
    networks:
      - automation-net

  # n8n — the workflow engine itself
  n8n:
    image: n8nio/n8n:latest
    container_name: n8n
    restart: unless-stopped
    ports:
      - "5678:5678"
    environment:
      - N8N_HOST=${N8N_HOST:-n8n.yourdomain.com}
      - N8N_PORT=5678
      - N8N_PROTOCOL=https
      - NODE_ENV=production
      - N8N_ENCRYPTION_KEY=${N8N_ENCRYPTION_KEY}
      # Database — tells n8n to use PostgreSQL instead of SQLite
      - DB_TYPE=postgresdb
      - DB_POSTGRESDB_HOST=postgres
      - DB_POSTGRESDB_PORT=5432
      - DB_POSTGRESDB_DATABASE=${POSTGRES_DB:-n8n}
      - DB_POSTGRESDB_USER=${POSTGRES_USER:-n8n}
      - DB_POSTGRESDB_PASSWORD=${POSTGRES_PASSWORD}
      # Queue mode — offloads execution to workers via Redis
      - EXECUTIONS_MODE=queue
      - QUEUE_BULL_REDIS_HOST=redis
      - QUEUE_BULL_REDIS_PORT=6379
      # Security — disable telemetry and public API unless needed
      - N8N_DIAGNOSTICS_ENABLED=false
      - N8N_PUBLIC_API_DISABLED=true
      # Timezone and binary data
      - GENERIC_TIMEZONE=${TZ:-Asia/Jakarta}
      - N8N_DEFAULT_BINARY_DATA_MODE=filesystem
    volumes:
      - ./n8n-data:/home/node/.n8n
      # Mount local files so n8n can read/write homelab scripts
      - /opt/scripts:/opt/scripts:ro
    depends_on:
      postgres:
        condition: service_healthy
      redis:
        condition: service_healthy
    networks:
      - automation-net

networks:
  automation-net:
    name: automation-net
    # Attach this network to your reverse proxy so n8n is accessible
    # externally (optional — keep it LAN-only if you VPN in)
    external: true

The .env file that accompanies this stack:

# .env — n8n secrets (chmod 600 this file)
POSTGRES_USER=n8n
POSTGRES_PASSWORD=generate-a-strong-random-password-here
POSTGRES_DB=n8n
# Generate with: openssl rand -base64 32
N8N_ENCRYPTION_KEY=your-base64-encryption-key-here
N8N_HOST=n8n.yourdomain.com
TZ=Asia/Jakarta

⚠️ Security note: The N8N_ENCRYPTION_KEY encrypts all credentials stored in n8n’s database. If you lose it, you lose access to every saved credential. Back it up in your password manager (/2026/06/vaultwarden-docker-compose-homelab/) and never commit it to git.

Essential n8n Credentials for Homelab Services

Once n8n is running at http://your-server:5678, configure credentials for the services it will orchestrate:

Service	n8n Node	Credentials Needed	Use Case
Proxmox	HTTP Request	API token (PVEAPIToken)	Query VM status, trigger backups
Docker socket	SSH / Execute Command	SSH key to Docker host	Restart containers, prune images
Uptime Kuma	Webhook (receiving)	None (n8n is the receiver)	Act on monitor status changes
Discord/Matrix	Discord / Matrix node	Bot token / access token	Send formatted alert messages
Ollama	HTTP Request	None (LAN API)	Send prompts for log summarization
Healthchecks.io	HTTP Request	Ping URL	Dead man’s switch for n8n itself

Building Your First Workflow: Proxmox Backup Alert

Here’s a practical n8n workflow that monitors Proxmox backup job completion and alerts you with an AI-generated summary. The workflow JSON can be imported directly into n8n:

{
  "name": "Proxmox Backup Monitor → Ollama Summary → Discord",
  "nodes": [
    {
      "name": "Cron Trigger",
      "type": "n8n-nodes-base.cron",
      "position": [250, 300],
      "parameters": {
        "triggerTimes": {
          "item": [{"mode": "everyHour"}]
        }
      }
    },
    {
      "name": "Check Proxmox Backup Status",
      "type": "n8n-nodes-base.httpRequest",
      "position": [450, 300],
      "parameters": {
        "url": "https://proxmox.local:8006/api2/json/nodes/pve/tasks",
        "authentication": "genericCredentialType",
        "genericAuthType": "httpHeaderAuth",
        "options": {
          "allowUnauthorizedCerts": true
        }
      }
    },
    {
      "name": "Filter Failed Backups",
      "type": "n8n-nodes-base.filter",
      "position": [650, 300],
      "parameters": {
        "conditions": {
          "string": [{
            "value1": "={{ $json.status }}",
            "operation": "equals",
            "value2": "FAILURE"
          }]
        }
      }
    },
    {
      "name": "Ollama: Summarize Failure",
      "type": "n8n-nodes-base.httpRequest",
      "position": [850, 300],
      "parameters": {
        "method": "POST",
        "url": "http://ollama:11434/api/generate",
        "body": {
          "model": "llama3.2:3b",
          "prompt": "=Summarize this Proxmox backup failure in one sentence for a homelab owner: {{ $json.status }} — task {{ $json.id }}",
          "stream": false
        }
      }
    },
    {
      "name": "Send Discord Alert",
      "type": "n8n-nodes-base.discord",
      "position": [1050, 300],
      "parameters": {
        "content": "=⚠️ Proxmox backup failure detected:\n{{ $json.response }}"
      }
    }
  ]
}

This workflow runs hourly, queries the Proxmox API for recent backup tasks, filters for failures, asks Ollama to summarize the failure in plain English, and posts the result to Discord. Total latency: ~3 seconds. Human involvement: zero.

Pillar 2: Self-Hosted Intelligence with Ollama

Why Local LLMs Belong in Your Automation Stack

Cloud AI APIs (OpenAI, Anthropic, Google) introduce three problems for automation: latency (API round-trips add 500ms–2s per call), cost (automation workflows run frequently — 24 checks/day × $0.01/request = $7.30/month for one workflow), and privacy (your logs, server names, and infrastructure details leave your network).

A local LLM running on your own hardware eliminates all three. Ollama makes this trivial — it bundles model weights, inference engine, and a REST API into a single binary. For automation tasks (summarization, classification, extracting structured data from logs), small models like Llama 3.2 3B or Phi-4 Mini perform exceptionally well with sub-second latency on consumer hardware.

Ollama Docker Compose + GPU/CPU Config

Add this to your automation stack:

# docker-compose.ollama.yml — Self-hosted LLM for automation intelligence
services:
  ollama:
    image: ollama/ollama:latest
    container_name: ollama
    restart: unless-stopped
    ports:
      - "11434:11434"
    environment:
      # Keep models loaded in memory between requests for instant response
      - OLLAMA_KEEP_ALIVE=24h
      # Limit concurrent requests to avoid overwhelming CPU
      - OLLAMA_NUM_PARALLEL=2
      # Set max model load time (models larger than 7B need more time)
      - OLLAMA_MAX_LOADED_MODELS=2
    volumes:
      - ./ollama-data:/root/.ollama
    # GPU support — uncomment the appropriate section below
    # === Intel ARC / iGPU (A380, A770, N100/N305 iGPU) ===
    # devices:
    #   - /dev/dri:/dev/dri
    # === NVIDIA GPU ===
    # deploy:
    #   resources:
    #     reservations:
    #       devices:
    #         - driver: nvidia
    #           count: 1
    #           capabilities: [gpu]
    networks:
      - automation-net

  # OpenWebUI — optional ChatGPT-style interface for testing prompts
  openwebui:
    image: ghcr.io/open-webui/open-webui:main
    container_name: openwebui
    restart: unless-stopped
    ports:
      - "3000:8080"
    environment:
      - OLLAMA_BASE_URL=http://ollama:11434
    volumes:
      - ./openwebui-data:/app/backend/data
    networks:
      - automation-net

networks:
  automation-net:
    external: true

Model selection for automation tasks:

Model	Size	RAM Needed	Latency (CPU)	Best For
Llama 3.2 3B	2.0 GB	4 GB	~800ms	Summarization, classification, alert triage
Phi-4 Mini	2.4 GB	4 GB	~600ms	Code explanation, structured extraction
Qwen 2.5 7B	4.7 GB	8 GB	~2s	Complex reasoning, multi-step analysis
Mistral 7B	4.1 GB	8 GB	~2.5s	General purpose, nuanced responses

For homelab automation, start with Llama 3.2 3B. It runs comfortably on an Intel N100 with 8 GB RAM, responds in under a second, and handles summarization and classification tasks reliably. Pull it once:

docker exec -it ollama ollama pull llama3.2:3b

n8n → Ollama Integration: AI-Powered Alert Summarization

The n8n HTTP Request node calls Ollama’s /api/generate endpoint. The critical parameters:

{
  "model": "llama3.2:3b",
  "prompt": "You are a homelab monitoring assistant. A service alert fired: [ALERT DETAILS]. Summarize in 1-2 sentences what happened, probable cause, and recommended action. Be specific — mention the service name and relevant log keywords.",
  "stream": false,
  "options": {
    "temperature": 0.1,
    "num_predict": 150
  }
}

Why temperature: 0.1: Automation summaries need consistency, not creativity. Low temperature ensures the same alert produces similar, reliable output every time. Why num_predict: 150: You’re asking for a 1-2 sentence summary — 150 tokens is plenty and keeps latency under 1 second.

Use Case: Smart Log Analysis Pipeline

Beyond simple summarization, the n8n + Ollama combination can process structured logs. Here’s the architecture:

Cron trigger fires every 6 hours
Execute Command node runs journalctl --since "6 hours ago" -p err --no-pager | tail -50 on target servers via SSH
n8n merges log output into a single text block
HTTP Request to Ollama with prompt: “Analyze these 50 system log errors from the past 6 hours. Group them by severity and service. Flag any patterns that indicate a developing problem. Output as JSON with keys: ‘critical’, ‘warnings’, ‘patterns’, ‘recommendation’.”
n8n parses the JSON response and routes critical items to Discord, warnings to a daily digest

This replaces the traditional logwatch email you stopped reading six months ago with a structured, prioritized, AI-curated digest.

Pillar 3: Observability with Uptime Kuma & Webhook Triggers

Beyond Ping: Uptime Kuma as an Event Source

Uptime Kuma is the most deployed monitoring tool in the self-hosted world — and most people use 20% of its capabilities. The webhook notification type transforms it from a dashboard into an event source for your automation stack.

Configure Uptime Kuma monitors for each critical service, but instead of sending alerts to Discord directly, configure them to fire webhooks at n8n. This gives n8n the chance to enrich, filter, and route the alert before it reaches you.

For a complete Uptime Kuma deployment guide, see our setup walkthrough at /2026/06/uptime-kuma-docker-compose-homelab-2026/.

In Uptime Kuma, create a notification of type Webhook with: - Post URL: http://n8n:5678/webhook/uptime-kuma-alert - Content-Type: application/json

The payload Uptime Kuma sends looks like this:

{
  "heartbeat": {
    "monitorID": 1,
    "status": 0,
    "time": "2026-06-11T03:14:22+07:00",
    "msg": "connect ECONNREFUSED 192.168.50.10:8096",
    "important": true
  },
  "monitor": {
    "id": 1,
    "name": "Jellyfin Media Server",
    "url": "http://192.168.50.10:8096",
    "type": "http",
    "interval": 60
  }
}

In n8n, the Webhook trigger node receives this payload. From there, your workflow can:

Deduplicate — check if this monitor already triggered within the last 10 minutes (avoid alert storms)
Enrich — query the container’s logs and resource usage
Analyze — send context to Ollama for root cause analysis
Attempt remediation — restart the container via Docker API or SSH
Escalate — if remediation fails after 2 attempts, send a notification to you

Building a Self-Healing Service Loop

Here’s the n8n workflow logic for a self-healing loop:

Webhook Trigger (Uptime Kuma alert)
  → IF (same monitor + last 10 min → already triggered)
      → Stop (deduplication — prevents alert storms)
  → Docker: Container Status (check if actually down)
      → IF (running but unreachable)
          → HTTP Request: Health check on container IP directly
          → IF (healthy) → Stop (false alarm — network blip)
      → Docker: Restart Container
      → Wait 30 seconds
      → HTTP Request: Health check
      → IF (healthy)
          → Discord: "Jellyfin auto-recovered after restart ✅"
          → Stop
      → IF (still down)
          → Ollama: Analyze docker logs for failure cause
          → Discord: "Jellyfin restart failed ❌ — AI analysis: [cause].
             Manual intervention needed. ssh user@host"

This is the “agentic” pattern in practice: detect, diagnose, remediate, escalate only when necessary. Each component is individually simple; the value comes from wiring them together.

The Complete Stack: Docker Compose Architecture

Network Design: Isolated Automation VLAN

The automation stack should live on its own Docker network, separate from your application containers. This prevents automation workflows from accidentally interfering with production services and makes it easy to control which services n8n can reach:

┌─────────────────────────────────────────────┐
│              automation-net                  │
│  ┌──────┐  ┌────────┐  ┌───────────────┐   │
│  │ n8n  │  │ Ollama │  │ Uptime Kuma   │   │
│  │:5678 │  │ :11434 │  │   :3001       │   │
│  └──┬───┘  └────────┘  └───────┬───────┘   │
│     │                           │            │
└─────┼───────────────────────────┼────────────┘
      │                           │
┌─────┼───────────────────────────┼────────────┐
│     │         app-net           │            │
│  ┌──┴──────────────────────────┴──┐         │
│  │   Jellyfin, Nextcloud, etc.    │         │
│  └────────────────────────────────┘         │
└──────────────────────────────────────────────┘

n8n can reach application containers via their Docker hostnames (if on the same network) or via the host’s LAN IP. Uptime Kuma monitors application services from the app-net side.

Environment Variables & Secrets Management

Centralize all secrets in a single .env file at the root of your automation stack directory:

# .env — Master secrets file for the automation stack
# Source this file before docker compose up

# PostgreSQL (n8n database)
POSTGRES_USER=n8n
POSTGRES_PASSWORD=CHANGE_ME_32_CHAR_MINIMUM
POSTGRES_DB=n8n

# n8n
N8N_ENCRYPTION_KEY=CHANGE_ME_OPENS_RAND_BASE64_32
N8N_HOST=automation.yourdomain.com

# Uptime Kuma
UPTIME_KUMA_PORT=3001

# Ollama
OLLAMA_KEEP_ALIVE=24h
OLLAMA_NUM_PARALLEL=2

# Timezone
TZ=Asia/Jakarta

Never commit .env to git. Add it to .gitignore immediately. Back it up separately in your password manager.

Resource Budget for Mini-PC Hosts

This stack runs well on modest hardware. Here’s what to expect:

Component	Idle CPU	Peak CPU	RAM	Disk	Notes
n8n + PostgreSQL + Redis	~2%	~15%	512 MB	2 GB	Peak during workflow execution
Ollama (Llama 3.2 3B)	~1%	~80%	2.5 GB	5 GB	CPU spikes during inference only
Uptime Kuma	~1%	~5%	128 MB	200 MB	Lightweight, constant polling
Total Stack	~4%	~100%	~3.5 GB	~8 GB	Fits on Intel N100 with 8–16 GB RAM

An Intel N100 mini PC ($150–200) handles this entire stack comfortably, with room for 10–15 application containers alongside it. If you use GPU acceleration (Ollama with Intel iGPU or NVIDIA), CPU load during inference drops from ~80% to ~10%.

Real-World Use Cases

Use Case 1: Intelligent Backup Health Monitor

Problem: Backup scripts run on cron. When they fail, you might not notice for days — or until you need the backup.

Solution: n8n watches backup completion signals and verifies backup integrity:

Restic backup script writes exit status to a file or sends a webhook on completion
n8n receives the signal and checks: Was the backup successful? How large was it? Did the size change significantly from yesterday (possible corruption)?
If anomaly detected: n8n sends the backup log to Ollama for analysis
Alert goes to Discord with AI summary and recommended action

For backup tool setup (Restic, Kopia, Duplicati), see our backup strategy guide at /2026/06/self-hosted-backup-strategy-homelab-2026/.

Use Case 2: Security Alert Triage

Problem: Wazuh generates dozens of alerts daily. Most are informational. Finding the critical ones requires manual log review.

Solution: Wazuh → n8n → Ollama → Matrix/Discord pipeline:

Wazuh (see /2026/06/wazuh-siem-setup/) sends webhook for severity 10+ alerts
n8n receives the alert, extracts the rule ID, agent, and raw log
Ollama classifies the alert: “This is a brute-force SSH attempt from external IP 203.0.113.42 targeting user ‘admin’. 47 failed attempts in 5 minutes. Recommendation: verify fail2ban is active, consider blocking the /24.”
n8n routes based on classification: critical → immediate notification; high → hourly digest; medium → daily summary

Use Case 3: Automated Certificate Renewal Alert

Problem: Nginx Proxy Manager auto-renews Let’s Encrypt certificates — but when renewal fails, you only notice when the cert expires and browsers show warnings.

Solution:

n8n Cron trigger runs weekly
HTTP Request queries NPM API for certificate expiry dates
Filter for certificates expiring within 14 days
If any found: n8n triggers manual renewal via NPM API
Verify renewal 5 minutes later
If still failing: Ollama analyzes the error and n8n alerts with probable cause (“DNS challenge failed for domain X — check that Cloudflare API token hasn’t expired”)

FAQ

Is n8n stable enough for production homelab use?

Yes. n8n has been production-grade since v1.0 (late 2023). The current release (v1.8x as of June 2026) includes queue mode for reliable workflow execution, built-in error handling with retry logic, and PostgreSQL-backed persistence. Self-hosted instances at homelab scale (dozens of workflows, hundreds of executions/day) run stably on 512 MB RAM. The primary failure mode is database corruption with SQLite — which is why this guide uses PostgreSQL from the start.

Do I need a GPU for Ollama in automation workflows?

No. For automation tasks (summarization, classification, structured extraction), CPU inference with small models (3B–7B parameters) is fast enough. Llama 3.2 3B on an Intel N100 CPU produces ~12 tokens/second — a 50-token summary takes ~4 seconds. Since automation workflows are asynchronous (you’re not waiting in a chat window), this latency is perfectly acceptable. A GPU helps if you use larger models or do real-time interactive prompting through OpenWebUI.

How does this compare to Ansible or Terraform?

Ansible and Terraform are configuration management tools — they define desired state and enforce it. n8n is a workflow automation tool — it responds to events. They complement each other: use Ansible to provision your servers and deploy your Docker stacks, use n8n to monitor, alert, and auto-remediate when things drift from that desired state. A mature homelab uses both.

Can I run this on a Raspberry Pi or Intel N100?

An Intel N100 (4-core, 6W TDP, ~$150) handles the full stack with headroom. A Raspberry Pi 5 (8 GB) can run n8n + Uptime Kuma comfortably, but Ollama is marginal — the 3B models technically run but at 3–5 tokens/second with significant swap pressure. For Pi-based setups, consider offloading Ollama to a separate machine or using an external API (with the privacy trade-off understood).

What about data privacy with n8n?

Self-hosted n8n stores all workflow data, credentials, and execution history in your PostgreSQL database — nothing leaves your server unless you configure a node to send data externally. The telemetry is opt-out (N8N_DIAGNOSTICS_ENABLED=false). Credential encryption is AES-256-GCM with your encryption key. For maximum privacy, keep n8n on an isolated VLAN with no internet access and use it purely for LAN automation.

How do I migrate from Zapier or Make to n8n?

n8n provides a migration guide at docs.n8n.io. The high-level process: (1) document your existing Zaps/scenarios, (2) recreate them in n8n using equivalent nodes (the node library covers most Zapier/Make integrations), (3) run both in parallel for a week to verify parity, (4) cut over. For custom integrations, n8n’s HTTP Request + Code nodes can replicate any API-based Zap that doesn’t have a native n8n node.

Can I integrate Home Assistant into this stack?

Yes — and it’s a natural fit. n8n has a native Home Assistant node that can trigger on state changes (motion detected, door opened, temperature threshold crossed) and call services (turn on lights, lock doors, arm alarm). Combined with Ollama, you can build workflows like: motion detected at 2 AM → Ollama analyzes camera snapshot → if person detected (not cat) → send alert with annotated image to Discord. See our Home Assistant Docker guide (forthcoming) for the full setup.

What’s the backup strategy for n8n workflows?

n8n stores workflows in PostgreSQL alongside execution data. Back up both: (1) the PostgreSQL database via pg_dump or automated Docker PostgreSQL backups, and (2) the n8n data directory (./n8n-data) which contains binary files and the encryption key backup. n8n also supports manual workflow export as JSON from the UI — export critical workflows as version-controlled files in a git repo for an additional safety layer.

Do I need all three pillars to get started?

No. Start with one pillar and add the others incrementally: - Week 1: Deploy Uptime Kuma with Discord notifications. Get basic monitoring working. - Week 2: Deploy n8n and redirect Uptime Kuma alerts to it. Build the deduplication logic. - Week 3: Deploy Ollama and add AI summarization to your alert pipeline. - Week 4: Build the first self-healing workflow (auto-restart a non-critical container).

Each step delivers value independently. The full stack is the destination, not the starting line.

Conclusion: Start Small, Think System-Wide

The 2026 homelab automation stack isn’t a product you install — it’s an architecture you build incrementally. The three pillars — n8n for orchestration, Ollama for intelligence, and Uptime Kuma for observability — each solve a real problem on their own. Wired together, they create something greater: infrastructure that watches itself, thinks about what it sees, and acts before you notice there’s a problem.

Start with a single workflow. The Proxmox backup alert from Pillar 1 takes 20 minutes to set up and immediately reduces your backup-anxiety. Add the self-healing loop from Pillar 3 and your Jellyfin server recovers before your family texts you. Wire in Ollama and your alerts stop being raw JSON payloads and start being actionable summaries.

The future of self-hosting is agentic — and it’s available today. You already have the hardware. The software is free. The only missing piece is the wiring, and this guide is your schematic.

Vaultwarden Docker Compose Setup for Homelab 2026: The Complete Self-Hosted Password Manager Guide

Vaultwarden Docker Compose Setup for Homelab 2026: The Complete Self-Hosted Password Manager Guide

Reading time: ~22 minutes Audience: Homelab operators who want complete control over their password vault — and anyone tired of paying subscriptions for password management

Introduction: Why Self-Host Your Password Manager?

Your password manager holds the keys to your digital life. Email. Banking. Cloud accounts. Social media. Your homelab admin panel. Every service you have ever signed up for lives behind a password — and if someone else controls the server that stores those passwords, you are trusting them with everything.

The Password Manager Problem

The three most popular password managers in 2026 — Bitwarden Cloud, 1Password, and Dashlane — all follow the same model: your encrypted vault lives on their servers. The encryption is zero-knowledge. The math is sound. But the servers are not yours. If their infrastructure goes down, you cannot log in. If their terms of service change, your data is subject to their policies. And if you manage credentials for fifty family members or a small business, the per-user pricing adds up fast — $40/user/year for Bitwarden Families, $60/user/year for 1Password, and even more at scale.

Subscription fatigue is real. A typical homelab operator already pays for a domain ($12/year), a VPS or power for a home server, possibly a Usenet indexer or two, and maybe cloud backup storage. Adding $40–$120/year for password management on top of that feels wrong — especially when you already own hardware that can run it for free.

Why Vaultwarden Over Bitwarden Cloud or 1Password?

Vaultwarden is an unofficial, open-source reimplementation of the Bitwarden server API written in Rust. It is compatible with every official Bitwarden client — browser extension, desktop app, mobile app, CLI — but it runs in a single Docker container using under 50 MB of RAM. The official Bitwarden server requires SQL Server, multiple microservices, and 2 GB of RAM minimum. Vaultwarden replaces all of that with SQLite and a single binary.

That is the simple sell: you get the best password manager ecosystem in the world, running on hardware you already own, for zero dollars. No subscription. No external dependency. No shared fate with Bitwarden’s CDN or cloud infrastructure.

And Vaultwarden actually includes features the official self-hosted Bitwarden server gatekeeps behind a paid license: TOTP storage, emergency access, attachments, sends, and organization collections. All free.

What This Guide Covers

This is not a shallow three-paragraph blog post with a Docker run command. By the end of this guide, you will have:

A production-grade Vaultwarden deployment with Docker Compose
HTTPS via your choice of Nginx Proxy Manager, Traefik, Caddy, or Cloudflare Tunnel
Passkeys and FIDO2 WebAuthn configured and tested
Fail2Ban intrusion protection blocking brute-force attempts
Automated encrypted backups to local NAS and offsite S3 storage
Uptime monitoring so you know before your vault goes dark
A full migration path from Bitwarden Cloud, 1Password, or Chrome

Every code block in this guide has been tested. Every decision matrix is based on real hardware numbers. Let’s build.

What Is Vaultwarden? (And How It Differs from Bitwarden)

Vaultwarden started in 2018 as “Bitwarden_RS” — a Rust port of the Bitwarden server API by developer Daniel García. It was later renamed to Vaultwarden to avoid trademark confusion with Bitwarden Inc. Despite being unofficial, it passes the Bitwarden server test suite and is trusted by tens of thousands of self-hosters worldwide.

Vaultwarden vs Bitwarden Official Server — Resource Comparison

Metric	Vaultwarden	Bitwarden Official
Language	Rust	C# (.NET)
Database	SQLite	Microsoft SQL Server
Minimum RAM	50 MB	2,000 MB (2 GB)
Container count	1	12+
Docker image size	~60 MB	~4 GB total
TOTP storage	Free	Paid license required
Emergency Access	Free	Paid license required
Attachments	Free	Paid license required
Organizations	Unlimited (free)	2-user limit on free tier
Send (file sharing)	Free	Paid license required
ARM / Raspberry Pi	Native	Not supported
Official Bitwarden client support	✅ Full	✅ Full

The takeaway is stark: for any homelab deployment — especially on a Raspberry Pi or low-power mini PC — Vaultwarden is not just the cheaper option. It is the only realistic option.

Vaultwarden vs Bitwarden Cloud vs 1Password — Feature Matrix

Feature	Vaultwarden (Free)	Bitwarden Cloud Free	Bitwarden Cloud Premium ($10/yr)	1Password ($36/yr)
Unlimited passwords	✅	✅	✅	✅
Browser extension	✅	✅	✅	✅
Mobile apps	✅	✅	✅	✅
TOTP 2FA codes	✅ Free	❌ (Premium only)	✅	✅
Passkeys / FIDO2	✅	✅	✅	✅
File attachments	✅ Free (1 GB default)	❌	✅ (1 GB)	✅ (1 GB)
Emergency Access	✅ Free	❌	✅ (trusted contact)	✅
Organizations / sharing	✅ Unlimited	❌ (2-person org trial)	✅ (Families: $40/yr)	✅ (Families: $60/yr)
Self-host option	✅ (Docker, 1 container)	✅ (but 2 GB RAM, SQL Server)	✅ (same requirements)	❌
Data residency	Your server	US cloud	US cloud	US/Canada/EU cloud
Breach / dark web monitoring	❌ (external tools)	❌ (Premium only via Watchtower)	✅ (Watchtower)	✅ (Watchtower)
Annual cost (family of 5)	$0	$0 (limited)	$40	$60

Important disclaimer: Vaultwarden is community-maintained and not affiliated with Bitwarden Inc. Your master password is the single point of failure — if you lose it, your vault is irrecoverable. No company can reset it for you. This is both the greatest strength and greatest risk of zero-knowledge encryption. Write your master password down and store it in a physically secure location.

Prerequisites & Planning

Before typing docker compose up, you need to make a few decisions.

Hardware Requirements

Vaultwarden is extraordinarily lightweight. Here is what you need:

Hardware	RAM Required	Storage	Notes
Raspberry Pi 3B+	1 GB (uses ~60 MB)	16 GB SD card	Works, but SD card longevity is a concern. Use external SSD.
Raspberry Pi 4 / 5	2–4 GB (uses ~80 MB)	32 GB+ SSD	Ideal low-power option. Active cooling recommended for Pi 5.
Mini PC (N100/N150)	8 GB (uses ~90 MB)	256 GB NVMe	The sweet spot. Runs alongside 20+ other Docker containers.
Proxmox LXC (1 vCPU, 512 MB)	512 MB VM allocation	32 GB virtual disk	Efficient. Use unprivileged LXC with Docker nested.
Budget VPS (1 vCPU, 1 GB)	1 GB (tight but works)	25 GB SSD	Acceptable. Use swap. Monitor OOM.

For a homelab deployment alongside other services, any modern Intel N100 mini PC or Proxmox LXC with 512 MB RAM allocated is more than sufficient.

Software Prerequisites

Docker Engine 24+ and Docker Compose v2+
A domain name you control (e.g., vault.yourdomain.com)
HTTPS (mandatory — the Bitwarden Web Crypto API refuses to run over plain HTTP)
Basic familiarity with Docker Compose (see our Docker Compose for Beginners guide)

Domain & HTTPS Strategy

The Web Crypto API used by the Bitwarden browser extension requires a secure context — meaning HTTPS. You cannot test this over http://192.168.50.66:8080. You need a valid TLS certificate. Four options:

Reverse proxy with Let’s Encrypt — NPM, Traefik, or Caddy handle certificates automatically
Cloudflare Tunnel — terminates TLS at Cloudflare edge, no open ports
Self-signed certificate — works technically but every client will complain. Not recommended.
Tailscale Funnel — exposes your service via Tailscale’s HTTPS proxy. Works without a domain.

For most homelab operators, Option 1 or 2 is the right answer.

Decision Matrix: Local Access vs Reverse Proxy vs Cloudflare Tunnel

Approach	HTTPS	Remote Access	Port Forwarding	Complexity	Best For
Local-only (Tailscale/WireGuard VPN)	Self-signed or internal CA	Via VPN only	None	Low	Users always on VPN
Nginx Proxy Manager	Auto Let’s Encrypt	Yes (port 443 open)	Yes (443→NPM)	Medium	Beginners wanting an admin UI
Traefik	Auto Let’s Encrypt	Yes (port 443 open)	Yes (443→Traefik)	Medium-High	Docker-native users, labels-based config
Caddy	Auto Let’s Encrypt	Yes (port 443 open)	Yes (443→Caddy)	Low-Medium	Users who want minimal config
Cloudflare Tunnel	Cloudflare edge	Yes	None	Low-Medium	Users behind CGNAT or without static IP

      # PUSH_ENABLED: "true"
      # PUSH_INSTALLATION_ID: "..."
      # PUSH_INSTALLATION_KEY: "..."

Why bind to 127.0.0.1? Binding to localhost ensures Vaultwarden is only reachable through your reverse proxy. If someone scans your public IP, port 8082 will not respond. Your reverse proxy (NPM/Traefik/Caddy) listens on 443 and proxies to http://vaultwarden:80 on the internal Docker network.

The .env File

# Vaultwarden Environment Variables
# ⚠️  Never commit this file to git!

# Admin token — generate with: openssl rand -base64 48 | argon2 "$(cat)" -id -e
# Or use the bash script in the next section
ADMIN_TOKEN='$argon2id$v=19$m=65540,t=3,p=4$...'

# SMTP Configuration (for email verification, invites, emergency access)
SMTP_HOST=smtp.gmail.com
SMTP_FROM=vaultwarden@yourdomain.com
SMTP_PORT=587
SMTP_SECURITY=starttls
SMTP_USERNAME=your-email@gmail.com
SMTP_PASSWORD=your-app-password   # Use Gmail App Password, not your real password

Generating a Secure ADMIN_TOKEN with Argon2id (2026 Standard)

The Vaultwarden admin panel is protected by a token hashed with Argon2id — the current password-hashing standard that won the Password Hashing Competition. Here is how to generate one:

#!/bin/bash
# generate-admin-token.sh — Generate an Argon2id ADMIN_TOKEN for Vaultwarden
# Requires: argon2 CLI (apt install argon2 / brew install argon2)

echo "Generating Vaultwarden ADMIN_TOKEN..."
echo "Enter your desired admin password (input hidden):"
read -s ADMIN_PASSWORD
echo ""

# Generate a random 48-byte salt
SALT=$(openssl rand -base64 48)

# Hash with Argon2id: 64 MB memory, 3 iterations, 4 parallelism
HASH=$(echo -n "$ADMIN_PASSWORD" | argon2 "$SALT" -id -t 3 -m 19 -p 4 -l 32 -e)

echo ""
echo "Add this to your .env file:"
echo "ADMIN_TOKEN='$HASH'"
echo ""
echo "⚠️  Save your admin password somewhere secure. You cannot recover it."

If you do not have argon2 CLI installed, you can generate the token using the Vaultwarden container itself:

# Alternative: Generate using Docker
docker run --rm -it vaultwarden/server /vaultwarden hash
# Enter your desired password when prompted

First Start & Health Check

# Start the stack
docker compose up -d

# Check container health
docker compose ps
# Expected: vaultwarden  Up 10 seconds (healthy)

# Check logs
docker compose logs -f vaultwarden
# Look for: "Starting Vaultwarden" and "Listening on 0.0.0.0:80"

Creating the First Admin Account

Navigate to https://vault.yourdomain.com/admin
Enter your ADMIN_TOKEN (the plaintext password, not the hash)
Go to Users → Invite User
Enter your email address and send the invitation
Open the invitation link and create your master password
Immediately disable open registration:

# In your .env or docker-compose.yml:
SIGNUPS_ALLOWED=false
docker compose up -d --force-recreate

Then verify by visiting https://vault.yourdomain.com/ — you should see a login page, not a signup form.

Reverse Proxy Integration (Choose Your Path)

Vaultwarden requires HTTPS. Choose one of the four options below.

Option A: Nginx Proxy Manager (Most Beginner-Friendly)

Nginx Proxy Manager (NPM) provides a web UI for managing proxy hosts and SSL certificates. If you already run NPM, add a new proxy host:

# Add to your existing docker-compose.yml with NPM
# Ensure vaultwarden and npm share a Docker network
networks:
  proxy:
    external: true   # Created by NPM or manually: docker network create proxy

services:
  vaultwarden:
    # ... (same as above) ...
    networks:
      - proxy
    # Remove the ports section entirely — NPM will reach it via container name

In the NPM web UI: 1. Proxy Hosts → Add Proxy Host 2. Domain: vault.yourdomain.com 3. Forward Hostname: vaultwarden (Docker container name) 4. Forward Port: 80 5. SSL tab → Request a new SSL certificate → Force SSL 6. Advanced tab → Paste:

# WebSocket support for live sync
location /notifications/hub {
    proxy_pass http://vaultwarden:3012;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

For full NPM setup, see our Nginx Proxy Manager Docker Compose guide.

Option B: Traefik (Labels-Based, Modern)

Traefik uses Docker labels for configuration — no separate config files:

services:
  vaultwarden:
    image: vaultwarden/server:latest
    # ... volumes and env as above ...
    networks:
      - traefik
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.vaultwarden.rule=Host(`vault.yourdomain.com`)"
      - "traefik.http.routers.vaultwarden.entrypoints=websecure"
      - "traefik.http.routers.vaultwarden.tls.certresolver=letsencrypt"
      - "traefik.http.services.vaultwarden.loadbalancer.server.port=80"
      # WebSocket
      - "traefik.http.routers.vaultwarden-websocket.rule=Host(`vault.yourdomain.com`) && PathPrefix(`/notifications/hub`)"
      - "traefik.http.routers.vaultwarden-websocket.entrypoints=websecure"
      - "traefik.http.routers.vaultwarden-websocket.tls.certresolver=letsencrypt"
      - "traefik.http.services.vaultwarden-websocket.loadbalancer.server.port=3012"

networks:
  traefik:
    external: true

For the full comparison of reverse proxies, see our Traefik vs NPM vs Caddy guide.

Option C: Caddy (Simplest Config)

Caddy handles TLS automatically with no configuration for the cert:

# Caddyfile
vault.yourdomain.com {
    reverse_proxy vaultwarden:80
    handle_path /notifications/hub {
        reverse_proxy vaultwarden:3012
    }
}

That is it. Caddy obtains and renews Let’s Encrypt certificates with zero additional config.

Option D: Cloudflare Tunnel (No Port Forwarding)

If you are behind CGNAT or cannot open ports, Cloudflare Tunnel is the best option:

# Add to your docker-compose.yml
services:
  cloudflared:
    image: cloudflare/cloudflared:latest
    command: tunnel run
    environment:
      - TUNNEL_TOKEN=${CF_TUNNEL_TOKEN}
    networks:
      - proxy

In the Cloudflare Zero Trust dashboard: 1. Create a tunnel → point vault.yourdomain.com to http://vaultwarden:80 2. Enable NoTLSVerify (traffic between cloudflared and Vaultwarden is local) 3. Add an Application Policy for email-based access control

For a complete guide, see our Cloudflare Tunnel Homelab setup.

Passkeys & FIDO2 Support (2026 Update)

Passkeys — the passwordless FIDO2/WebAuthn standard — are now the default authentication method on iOS, Android, and major browsers. Vaultwarden has supported WebAuthn since 2023, and as of 2026, the implementation is production-stable.

Enabling WebAuthn in Vaultwarden

No special config is needed — WebAuthn is enabled by default. What you need:

A domain with valid HTTPS (WebAuthn requires a secure context)
A FIDO2 security key (YubiKey, Google Titan, Nitrokey) or a platform authenticator (Windows Hello, Apple Touch ID / Face ID, Android biometric)

Registering a YubiKey or Passkey

Log in to your Vaultwarden web vault at https://vault.yourdomain.com
Go to Settings → Security → Two-step Login
Under FIDO2 WebAuthn, click Manage
Enter your master password to confirm
Click Add Key → give it a name (e.g., “YubiKey 5C NFC”)
Insert your security key and tap it when prompted
Optional: repeat for a backup key

For platform passkeys (no hardware key needed): - On macOS: Safari or Chrome → Touch ID will be offered - On Windows: Edge or Chrome → Windows Hello PIN or fingerprint - On Android: Chrome → fingerprint or screen lock - On iOS: Safari → Face ID or Touch ID

Backup Codes and Recovery Strategy

Critical: If you lose all your WebAuthn devices, your vault is locked. Vaultwarden generates one-time recovery codes when you enable any 2FA method:

After enabling FIDO2, click View Recovery Codes
Print them. Do not store them digitally in the same device.
Store one copy in a fireproof safe, one copy with a trusted family member
Test one recovery code to verify they work

Security Hardening (Don’t Skip This)

A password manager that is not hardened is a liability. Follow every step.

Disable Open Registration

After creating your user account, lock registration:

# In .env:
SIGNUPS_ALLOWED=false
INVITATIONS_ALLOWED=false

Enable 2FA / TOTP for Admin

Vaultwarden supports TOTP (time-based one-time passwords) natively — and unlike Bitwarden Cloud, it is free:

Web vault → Settings → Security → Two-step Login
Under Authenticator App, click Manage
Scan the QR code with Aegis (Android), Raivo (iOS), or 2FAS
Enter the 6-digit code to confirm
Save recovery codes!

Fail2Ban Integration (Docker-Aware Config)

Fail2Ban blocks IPs after repeated failed login attempts. For a Docker deployment:

# /etc/fail2ban/jail.local — Add this block:
[vaultwarden]
enabled = true
port = 80,443,3012
filter = vaultwarden
logpath = /opt/vaultwarden/vw-data/vaultwarden.log
maxretry = 5
findtime = 300
bantime = 3600
chain = DOCKER-USER

# /etc/fail2ban/filter.d/vaultwarden.conf
[Definition]
failregex = ^.*Username or password is incorrect\. Try again\. IP: <ADDR>.*$
            ^.*Invalid admin token\. IP: <ADDR>.*$
            ^.*2FA token not provided.* IP: <ADDR>.*$
ignoreregex =

# Verify the filter works:
fail2ban-regex /opt/vaultwarden/vw-data/vaultwarden.log /etc/fail2ban/filter.d/vaultwarden.conf
# Restart Fail2Ban:
systemctl restart fail2ban
# Check status:
fail2ban-client status vaultwarden

Firewall Rules (UFW)

# Only allow 443 and 80 from anywhere (for reverse proxy)
ufw allow 443/tcp
ufw allow 80/tcp
# Block Vaultwarden's internal port from external access
ufw deny 8082/tcp
# Only allow SSH from your local network
ufw allow from 192.168.1.0/24 to any port 22

Disable Unused Features

If you do not use certain features, disable them to reduce attack surface:

# In .env:
SENDS_ALLOWED=false           # If you don't use Bitwarden Send
EMERGENCY_ACCESS_ALLOWED=false # If you don't use emergency contacts
ORG_CREATION_USERS=none       # If you're the only user

Client Setup & Migration

Browser Extension Configuration

Install the Bitwarden browser extension (Firefox Add-ons / Chrome Web Store)
Open the extension → Settings (gear icon) → Self-hosted Environment
Set Server URL to https://vault.yourdomain.com
Enter your email and master password → Log in

Desktop App

The Bitwarden desktop app (Windows, macOS, Linux) supports custom server URLs: - Settings → Self-hosted Environment → enter your URL - The app also supports biometric unlock (Windows Hello, Touch ID) once configured

Mobile Apps (iOS, Android)

Download Bitwarden from the App Store or Google Play
Tap the gear icon on the login screen → Self-hosted Environment → enter your URL
Enable biometric unlock in Settings after login

Migrating from Bitwarden Cloud / 1Password / Chrome

From Bitwarden Cloud: 1. Log in to your Bitwarden Cloud vault 2. Tools → Export Vault → .json (unencrypted) — do this on a trusted device 3. Log in to your Vaultwarden instance 4. Tools → Import Data → Bitwarden (json) → select file

From 1Password: 1. 1Password desktop app → File → Export → .1pux or .csv 2. In Vaultwarden: Tools → Import Data → 1Password 1pux or csv

From Chrome/Edge password manager: 1. chrome://password-manager/settings → Export passwords → .csv 2. In Vaultwarden: Tools → Import Data → Chrome (csv)

Security note: After import, securely delete the unencrypted export file. On Linux: shred -u export.json. On macOS: rm -P export.json. On Windows: use cipher /w or a file shredder tool.

CLI & Vaultwarden API

The official Bitwarden CLI (bw) works with Vaultwarden:

# Install
npm install -g @bitwarden/cli
# Or: brew install bitwarden-cli

# Configure custom server
bw config server https://vault.yourdomain.com

# Login
bw login
# Enter email and master password

# Unlock session
export BW_SESSION=$(bw unlock --raw)

# List all items
bw list items --session $BW_SESSION

Backup & Disaster Recovery

Your password vault is the single most important dataset in your homelab. Back it up.

What to Back Up

Data	Location	Criticality
SQLite database	`vw-data/db.sqlite3`	🔴 Critical — all vault data, users, orgs
Attachments	`vw-data/attachments/`	🟡 Important — user-uploaded files
Config	`vw-data/config.json`	🟡 Important — server config, org keys
RSA key pair	`vw-data/rsa_key.pem`	🟡 Important — used for token signing
Icon cache	`vw-data/icon_cache/`	🟢 Optional — regenerates automatically
Docker Compose	`docker-compose.yml`	🟡 Important — your deployment config
.env file	`.env`	🔴 Critical — contains ADMIN_TOKEN hash
Fail2Ban configs	`/etc/fail2ban/jail.local`, `filter.d/`	🟢 Optional — rebuildable

Minimum viable backup: vw-data/db.sqlite3 + vw-data/attachments/ + docker-compose.yml + .env

Automated Backup with Restic

Restic is our recommended backup tool for Vaultwarden. Here is a Docker Compose sidecar:

# Add to your docker-compose.yml
services:
  vaultwarden-backup:
    image: restic/restic:latest
    container_name: vaultwarden-backup
    restart: unless-stopped
    volumes:
      - ./vw-data:/data:ro          # Read-only mount — Vaultwarden data
      - ./restic-cache:/cache
      - ./restic-password:/password:ro
    environment:
      RESTIC_REPOSITORY: "s3:s3.amazonaws.com/your-bucket/vaultwarden"
      RESTIC_PASSWORD_FILE: "/password/restic-password.txt"
      AWS_ACCESS_KEY_ID: "${AWS_ACCESS_KEY_ID}"
      AWS_SECRET_ACCESS_KEY: "${AWS_SECRET_ACCESS_KEY}"
    entrypoint: >
      /bin/sh -c "
      while true; do
        restic backup /data \
          --exclude 'icon_cache' \
          --host vaultwarden \
          --tag automated \
          && restic forget --keep-daily 7 --keep-weekly 4 --keep-monthly 6 --prune \
          && restic check;
        sleep 86400;
      done
      "

Offsite Backup Strategy

A backup on the same physical machine is not a backup. Follow at minimum a 3-copy strategy:

Tier	Destination	Cost	Latency
Local NAS	Synology / TrueNAS / Unraid SMB share	$0 (existing hardware)	<1 ms
Offsite S3	Backblaze B2, Cloudflare R2, Hetzner Storage Box	$0–$5/mo	20–80 ms
Cold storage	External USB SSD rotated monthly	$30 one-time	Manual

For a complete 3-2-1 backup framework, see our Self-Hosted Backup Strategy guide.

Restore Procedure

# 1. Stop Vaultwarden
docker compose stop vaultwarden

# 2. Restore from latest Restic snapshot
restic restore latest --target /tmp/vaultwarden-restore

# 3. Copy restored data
cp /tmp/vaultwarden-restore/db.sqlite3 ./vw-data/
cp -r /tmp/vaultwarden-restore/attachments/ ./vw-data/
cp /tmp/vaultwarden-restore/config.json ./vw-data/
cp /tmp/vaultwarden-restore/rsa_key.pem ./vw-data/

# 4. Fix permissions
chown -R 1000:1000 ./vw-data/

# 5. Start Vaultwarden
docker compose up -d vaultwarden

# 6. Verify
curl -s https://vault.yourdomain.com | grep "Vaultwarden"

Backup Verification

A backup you have never restored is Schrödinger’s backup — it is both working and not working until you test it. At minimum:

# Monthly: restore to a test directory and verify SQLite integrity
restic restore latest --target /tmp/vw-test
sqlite3 /tmp/vw-test/db.sqlite3 "PRAGMA integrity_check;"
# Expected: "ok"

Monitoring & Alerts

If Vaultwarden goes down, you need to know before you need a password.

Uptime Kuma Push Monitor

# Add to Uptime Kuma: Push monitor → Push URL
# Then add to Vaultwarden's health check:
curl -s https://uptime.yourdomain.com/api/push/YOUR_PUSH_TOKEN?status=up&msg=Vaultwarden+OK

Or use Uptime Kuma’s HTTP(s) monitor to check https://vault.yourdomain.com every 60 seconds. See our Uptime Kuma Docker Compose guide for full setup.

Prometheus Metrics

Vaultwarden can expose a Prometheus metrics endpoint:

# .env:
EXPERIMENTAL_CLIENT_FEATURE_FLAGS=fido2-vault-credentials

For a full monitoring stack, see our Grafana + Prometheus setup.

Upgrading Vaultwarden

Safe Update Procedure

# 1. Backup (always)
docker compose stop vaultwarden
cp ./vw-data/db.sqlite3 ./vw-data/db.sqlite3.backup-$(date +%Y%m%d)

# 2. Pull and recreate
docker compose pull vaultwarden
docker compose up -d vaultwarden

# 3. Check logs for migration messages
docker compose logs -f vaultwarden
# Watch for: "Running migrations" and "Migration complete"

Rollback Strategy

# If something breaks after update:
# 1. Check the release notes — was there a breaking change?
# 2. Pin to previous version in docker-compose.yml:
#    image: vaultwarden/server:1.32.0  (instead of :latest)
# 3. Restore the pre-update database:
cp ./vw-data/db.sqlite3.backup-YYYYMMDD ./vw-data/db.sqlite3
docker compose up -d vaultwarden

Troubleshooting Common Issues

HTTPS Errors & Web Crypto API

Symptom: Browser extension says “An error has occurred. Failed to fetch.”

Root cause: The Web Crypto API requires HTTPS. You are accessing Vaultwarden over plain HTTP.

Fix: Configure a reverse proxy with TLS. Even a self-signed certificate on a .local domain can work, but Let’s Encrypt via NPM/Traefik/Caddy is the proper solution.

Admin Token Not Working

Symptom: “Invalid admin token” when accessing /admin.

Fixes: 1. Ensure you are using the plaintext password, not the Argon2id hash 2. Regenerate: docker compose exec vaultwarden /vaultwarden hash 3. Check for trailing whitespace in .env — ADMIN_TOKEN='$argon2...' not ADMIN_TOKEN='$argon2... '

SMTP / Email Not Sending

Symptom: No invitation emails, no verification emails.

Fixes: 1. Check SMTP_PORT matches security: 587 for STARTTLS, 465 for force_tls 2. For Gmail: you must use an App Password, not your account password 3. Test connectivity: docker compose exec vaultwarden nc -zv smtp.gmail.com 587

Mobile Sync Issues

Symptom: Passwords added on desktop don’t appear on mobile.

Fixes: 1. Ensure WebSocket is enabled (WEBSOCKET_ENABLED=true) 2. Verify your reverse proxy passes WebSocket connections (port 3012) 3. Force sync: mobile app → Settings → Sync vault now

Database Locked / Corruption

Symptom: Vaultwarden starts but logs “database is locked.”

Fixes: 1. Stop all Vaultwarden processes: docker compose stop 2. Check SQLite integrity: sqlite3 vw-data/db.sqlite3 "PRAGMA integrity_check;" 3. If corrupted, restore from backup (you did back up, right?)

Passkey Registration Fails

Symptom: WebAuthn registration returns “The operation failed for an unknown reason.”

Fixes: 1. Verify the domain has valid HTTPS (self-signed certs cause WebAuthn failures) 2. The domain in DOMAIN env var must exactly match the URL in your browser (include https://) 3. Some browsers require user gesture — click explicitly, do not use auto-focus 4. Safari requires the domain to have a valid certificate in the Keychain

FAQ

Is Vaultwarden safe for production?

Yes, with caveats. Vaultwarden is used by tens of thousands of self-hosters. It passes the Bitwarden server test suite. The cryptography is identical — all encryption/decryption happens client-side in the Bitwarden apps. Vaultwarden never sees your master password or decrypted vault. However, it is community-maintained and not officially supported by Bitwarden. For enterprises with compliance requirements (SOC2, HIPAA), use Bitwarden’s official self-hosted server.

Can I use official Bitwarden apps with Vaultwarden?

Yes. Every official Bitwarden client — browser extension, desktop app (Windows/macOS/Linux), mobile apps (iOS/Android), and CLI — works with Vaultwarden by changing one setting: Server URL.

How do I reset the admin token?

If you lose your admin password, regenerate the token hash:

docker compose exec vaultwarden /vaultwarden hash

Then update ADMIN_TOKEN in your .env and run docker compose up -d. You do not need the old password.

Does Vaultwarden support passkeys?

Yes. FIDO2 WebAuthn (passkeys) is fully supported and enabled by default. You can use hardware security keys (YubiKey, Titan) or platform authenticators (Windows Hello, Touch ID). This is a 2026 strength — many competitors’ self-hosted options still lack passkey support.

Can I run Vaultwarden on a Raspberry Pi?

Yes. Vaultwarden runs comfortably on a Raspberry Pi 4 with 2 GB RAM, using approximately 80 MB of memory. For a Pi 3B+, it works but use an external SSD rather than an SD card — SQLite writes will destroy an SD card within months.

How do I migrate from Bitwarden Cloud?

Export your vault as .json from Bitwarden Cloud (Tools → Export Vault), then import into Vaultwarden (Tools → Import Data). The process takes under two minutes. Securely delete the export file afterward.

What happens if my server dies?

If you have a backup of db.sqlite3 and attachments/, you can restore to any Docker host and be back online in minutes. If you do not have a backup, your data is gone permanently. Zero-knowledge encryption means nobody can recover it — not Vaultwarden’s developers, not Bitwarden Inc., not your VPS provider. This is why backup is not optional.

Is SSO supported?

Vaultwarden does not natively support SAML or OIDC. However, you can put Authelia or Authentik in front of Vaultwarden as a reverse proxy middleware for SSO. This protects the login page but does not replace the master password — you still need it to decrypt the vault. For the admin panel specifically, Authelia can gate access behind SSO.

Can I share passwords with family?

Yes. Vaultwarden supports Organizations and Collections — the same sharing model as Bitwarden. Create an organization, invite family members by email, and assign passwords to shared collections. Unlike Bitwarden Cloud, there is no per-user fee for organizations.

How do I enable Dark Web monitoring?

Vaultwarden does not have native breach monitoring. Use external tools: - Have I Been Pwned API (free for individual checks) - Bitwarden Watchtower (built into clients, works with Vaultwarden) - Firefox Monitor (free) - Google Password Checkup (works with exported CSV)

Conclusion & Next Steps

You now have a production-grade, self-hosted password manager running in your homelab — with HTTPS, two-factor authentication, passkeys, automated backups, intrusion detection, and monitoring. You are no longer paying a subscription for password management, and your vault lives on hardware you control.

When to Choose Vaultwarden vs Bitwarden Cloud

Choose Vaultwarden if…	Choose Bitwarden Cloud if…
You already run a homelab with Docker	You want zero maintenance
You want full data residency control	You need SOC2/HIPAA compliance
You manage passwords for 5+ family members	You don’t have reliable home internet
You want TOTP and attachments for free	You need official support channels
You enjoy self-hosting as a hobby	You want breach monitoring built in

Docker Compose vs. K3S for Homelab: Which Orchestration Level Do You Actually Need in 2026?

2026-06-10T00:00:00+07:00

Docker Compose vs. K3S for Homelab: Which Orchestration Level Do You Actually Need in 2026?

Reading time: ~11 minutes | Audience: Intermediate homelab users managing 3–20+ services who feel they’re outgrowing basic Docker

The homelab ecosystem has evolved dramatically. In 2026, the question is no longer “should I run self-hosted services” — it’s “how do I manage them without losing my mind?” As your library of services grows from a few containers on a Raspberry Pi to a full rack of infrastructure, you inevitably face the orchestration divide: the battle-tested simplicity of Docker Compose versus the sophisticated scalability of K3S.

This isn’t a theoretical debate. The orchestration layer you choose today determines how much time you spend maintaining your homelab versus actually using it. Let’s break this down with real deployment examples, not marketing bullet points.

1. The Evolution of Homelab Orchestration — and Why It Matters Now

In the early days of a homelab journey, almost everyone starts with raw Docker commands. You pull an image, map a port, and you’re off. But as your services multiply, you begin to experience “container fatigue.” You have dozens of individual docker run commands scattered across text files, configuration drift is common, and updating an entire suite of applications feels like a part-time job.

This is the precise moment when orchestrators become tempting. You are no longer just running services; you are building an environment. The question is: do you need the simple, declarative orchestration of Docker Compose, or is your infrastructure ready for the clustered, self-healing power of K3S?

Most homelabbers reach this crossroads somewhere between 10 and 30 services. If you’ve already set up a reverse proxy with Nginx Proxy Manager and have a handful of services behind it, you’re exactly at this inflection point.

2. The Case for Docker Compose: Simple, Proven, and Battle-Tested

For the vast majority of self-hosters, Docker Compose is the sweet spot. It was purpose-built to define and run multi-container applications, and it excels at exactly that.

What Docker Compose Gets Right

Dead-simple syntax. A docker-compose.yml file is human-readable and takes minutes to learn. Here’s a real-world example — a typical homelab stack with Portainer for management and Pi-hole for DNS:

version: "3.8"
services:
  portainer:
    image: portainer/portainer-ce:latest
    container_name: portainer
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./portainer-data:/data
    ports:
      - "9443:9443"

  pihole:
    image: pihole/pihole:latest
    container_name: pihole
    restart: unless-stopped
    environment:
      TZ: "Asia/Jakarta"
      WEBPASSWORD: "${PIHOLE_PASSWORD}"
    volumes:
      - ./pihole/etc-pihole:/etc/pihole
      - ./pihole/etc-dnsmasq.d:/etc/dnsmasq.d
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "8080:80/tcp"
    cap_add:
      - NET_ADMIN

One command — docker compose up -d — brings the entire stack online. No cluster setup, no control plane, no certificates to manage. It just works.

Near-zero overhead. Docker is a lean engine. It doesn’t require a master node, an etcd database, or complex networking overlays. On a Proxmox beginner setup, you can run Docker Compose on an LXC container with 2 GB RAM and still have room for 10+ lightweight services.

Infrastructure-as-code, practically. Store your docker-compose.yml files in a self-hosted Git forge and you’ve got version-controlled infrastructure without touching YAML indentation hell. For most home labs, this is the sweet spot between manual docker run and full-blown GitOps.

When Docker Compose Hits Its Limits

Docker Compose shines on a single host, but it wasn’t designed for: - Multi-node deployments. Spreading services across 3 physical servers requires manual port mapping, shared storage, and a lot of hope. - Self-healing. If a container crashes, Compose restarts it. If a server crashes, you’re waking up at 3 AM. - Rolling updates with zero downtime. Compose can restart containers, but it can’t drain traffic first.

For most homelabbers with 1–3 nodes, these limitations are academic. But if you’ve already got a monitoring stack with Prometheus tracking uptime across multiple machines, you’re edging into K3S territory.

Stick with Docker Compose If…

You have 1–3 physical servers.
Your primary goal is using your services, not managing infrastructure.
You prefer the “set it and forget it” approach to maintenance.
You’re comfortable with Portainer for visual management.

3. The Leap to K3S: Lightweight Kubernetes for the Homelab

When your homelab grows to include multiple physical nodes, high-availability requirements, or a genuine need to learn industry-standard orchestration, K3S enters the discussion.

What Exactly Is K3S?

K3S is a CNCF-certified Kubernetes distribution built by Rancher Labs (now SUSE). It’s packaged as a single binary under 100 MB, strips out legacy cloud-provider plugins, and replaces etcd with an embedded SQLite database — all optimizations that make it runnable on hardware that would choke on a full Kubernetes install.

Installation on a master node is almost comically simple:

curl -sfL https://get.k3s.io | sh -

That’s it. Your control plane is running. Joining a worker node takes one command:

curl -sfL https://get.k3s.io | K3S_URL=https://<master-ip>:6443 K3S_TOKEN=<node-token> sh -

What K3S Unlocks That Compose Cannot

Declarative desired state. You define your entire application stack in YAML manifests, and K3S continuously reconciles reality against that definition. If a pod dies, it’s recreated. If a node goes offline, workloads reschedule. Here’s that same Pi-hole stack, expressed as a Kubernetes Deployment:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: pihole
  namespace: networking
spec:
  replicas: 1
  selector:
    matchLabels:
      app: pihole
  template:
    metadata:
      labels:
        app: pihole
    spec:
      containers:
      - name: pihole
        image: pihole/pihole:latest
        env:
        - name: TZ
          value: "Asia/Jakarta"
        ports:
        - containerPort: 53
          protocol: TCP
        - containerPort: 53
          protocol: UDP
        - containerPort: 80
        volumeMounts:
        - name: etc-pihole
          mountPath: /etc/pihole
      volumes:
      - name: etc-pihole
        persistentVolumeClaim:
          claimName: pihole-config-pvc
---
apiVersion: v1
kind: Service
metadata:
  name: pihole-dns
  namespace: networking
spec:
  type: LoadBalancer
  ports:
  - port: 53
    targetPort: 53
    protocol: UDP
  selector:
    app: pihole

Yes, it’s more YAML. But you’re buying: automatic rescheduling on node failure, rolling updates with kubectl rollout, and the ability to kubectl apply -f the same manifest to any cluster.

Native high availability. With three K3S master nodes (or two masters + an external database), your control plane survives node failures. Services with replicas: 2 or more stay available even if a worker node goes down. For critical services like Vaultwarden for password management or Home Assistant, this isn’t a luxury — it’s peace of mind.

Industry-standard skills. Every hour you spend learning K3S is an hour invested in the technology that runs most of the internet. kubectl, Helm charts, and Ingress controllers aren’t just homelab toys — they’re resume line items.

Upgrade to K3S If…

You’re managing 4+ physical nodes and want a unified cluster view.
You run services that require uptime — family photo storage, home automation, your partner’s Plex server.
You’re actively building DevOps skills for your career.
You’ve already automated your Compose deployments and want the next challenge.

4. Comparison Matrix: Docker Compose vs. K3S — All the Factors That Matter

Talking about orchestration without a comparison table is like describing a server rack without listing specs. Here’s the honest breakdown:

Factor	Docker Compose	K3S
Learning Curve	Hours	Weeks
Setup Time (first deploy)	5 minutes	30–60 minutes

The Hidden Cost: Maintenance Burden

This is where most comparisons miss the point. The real cost of an orchestrator isn’t the RAM it consumes — it’s the hours you spend keeping it healthy.

With Docker Compose, maintenance looks like: docker compose pull && docker compose up -d once a week. You might need to fix a broken volume mount once every few months.

With K3S, maintenance includes: certificate rotation (automatic but worth monitoring), etcd backups (you are backing these up, right?), Ingress controller updates, CNI plugin compatibility checks, and the occasional kubectl describe pod rabbit hole at 11 PM.

One homelabber’s rule of thumb: If you spend more than 2 hours per week on infrastructure maintenance, your orchestrator is too complex for your actual needs.

5. The 2026 Decision Framework: What Should You Actually Run?

Forget the hype. Here’s a practical decision tree based on what homelabbers are actually running in 2026:

Path A: Start with Docker Compose (Recommended for ~85% of homelabbers)

Your setup: 1–3 nodes (mix of mini PCs or used enterprise gear).
Your goal: Running services, not managing infrastructure.
Your stack: Portainer or Dockge for visual management, Nginx Proxy Manager for reverse proxy, and a Git repo for compose file backup. See this pattern in action with our Uptime Kuma monitoring guide.
When to reconsider: If you hit 3+ nodes and your compose files are scattered across machines, or if you’re manually SSH-ing to restart services more than once a week.

Path B: Go K3S (For the ~15% who’ve outgrown Compose)

Your setup: 4+ nodes, at least one with 8+ GB RAM for the control plane.
Your goal: Learn production-grade orchestration or run services that genuinely need HA.
Your stack: K3S + MetalLB for load balancing + Traefik Ingress + Longhorn for storage. Expect to invest 10–20 hours upfront.
The hybrid approach: Some homelabbers run Docker Compose on their “production” node (services the family uses) while maintaining a separate K3S cluster for learning and experimentation. This is a valid middle ground that avoids the “my spouse can’t reach Jellyfin because I broke the CNI plugin” scenario.

The “Gateway Drug” Pattern

Many successful homelabbers follow this progression:

Phase 1: Raw docker run commands → realize this doesn’t scale
Phase 2: Docker Compose + Portainer → smooth sailing for 1–2 years
Phase 3: Curiosity piqued → spin up a K3S cluster on spare hardware
Phase 4: Migrate non-critical services to K3S for learning
Phase 5: Either go all-in on K3S or settle into a hybrid setup

The key insight: you don’t have to jump from Phase 2 to Phase 5 in one weekend. The hybrid approach — running both simultaneously on separate hardware — is the most common (and least stressful) pattern in 2026.

6. The Hybrid Reality: Running Both in 2026

Here’s a real scenario from the WordForge homelab: we run Docker Compose on our primary Proxmox node (where family-critical services like Pi-hole DNS and the reverse proxy live) while maintaining a separate 3-node K3S cluster on repurposed hardware for experimentation.

The Compose node runs 15+ services with near-zero weekly maintenance. The K3S cluster runs test deployments, CI/CD pipelines, and services we’re evaluating before promoting to the “production” Compose node. When the K3S cluster breaks (and it will — that’s the point of a learning environment), nobody notices except you.

This pattern turns the “Compose vs. K3S” debate from a binary choice into a spectrum. You’re not choosing one forever — you’re choosing what’s right for this phase of your homelab.

When the Hybrid Pattern Makes Sense

You want to learn Kubernetes without risking family-critical services.
You have spare hardware (old mini PCs, retired laptops) that can run K3S agents.
You want to test infrastructure changes in K3S before applying equivalent changes to your Compose setup.

7. Conclusion: Orchestration Is a Spectrum, Not a Binary Choice

There is no universally “better” orchestrator — only the one that matches your current infrastructure, time budget, and tolerance for complexity. Docker Compose remains the undisputed champion for single-node and small multi-node homelabs in 2026. K3S is the logical next step when you’ve genuinely outgrown Compose’s single-host model and are ready to invest real time in platform management.

The most common mistake? Jumping to K3S too early. If you’re still learning how reverse proxies work or troubleshooting volume permissions, Kubernetes will multiply your problems, not solve them. Master Docker Compose first — our Portainer guide is a good place to start if you want visual container management — and only graduate to K3S when the limitations of single-host orchestration are actually blocking you, not because a Reddit thread made you feel like you’re missing out.

Frequently Asked Questions

Q: Can I run Docker Compose and K3S side by side on the same node? A: Technically yes, but we strongly advise against it. Both want to manage containers and networking, and conflicts are inevitable. Use separate physical or virtual machines. If you’re on Proxmox, dedicate one VM to Compose and a separate set of VMs/LXCs to your K3S cluster.

Q: Is K3S too resource-heavy for a Raspberry Pi cluster? A: Not at all. K3S was designed for ARM and edge devices. A Pi 5 with 8 GB RAM can run the control plane, and Pi 4s make fine worker nodes. Just keep your workload pods lightweight — don’t expect Jellyfin with 4K transcoding to run well on a Pi.

Q: How do I migrate from Docker Compose to K3S? A: There’s no automated “lift and shift” tool. The migration path is: (1) convert your docker-compose.yml to Kubernetes manifests (Deployments, Services, ConfigMaps), (2) set up persistent storage with PVCs matching your old bind mounts, (3) test the new deployment on K3S in parallel, (4) switch DNS/reverse proxy to point to the K3S service IPs, (5) decommission the Compose stack. Budget a full weekend for 10–15 services.

Q: What about Podman or Docker Swarm? Aren’t those options too? A: Podman is an excellent Docker alternative with better security defaults (rootless by design), and it has its own Compose-equivalent (podman-compose). Docker Swarm is still functional but has been in maintenance mode since Mirantis acquired Docker Enterprise. For new deployments in 2026, choose between Compose and K3S — Swarm is a dead end.

Q: Will learning K3S help my career? A: Absolutely. Kubernetes skills — even from a homelab K3S cluster — transfer directly to EKS, GKE, and AKS in production environments. Being able to say “I run Kubernetes at home” in an interview is a strong signal.

Q: Which reverse proxy should I use with K3S? A: Traefik ships as the default Ingress controller in K3S and integrates natively with Kubernetes Ingress resources. If you’re coming from Nginx Proxy Manager, be prepared for a learning curve — Traefik configuration is YAML-based, not GUI-based. Some homelabbers run Nginx Ingress instead for familiarity.

Q: How do I back up a K3S cluster vs. a Docker Compose setup? A: For Compose: rsync your volumes and git-push your compose files. Done in 5 minutes. For K3S: you need etcd snapshots (k3s etcd-snapshot), PersistentVolume backups (Velero, Longhorn snapshots, or good old rsync if using hostPath volumes), and your manifest repo. More moving parts, more diligence required.

Mastering Docker Networking: A Battle-Tested Guide for Homelabbers

2026-06-10T00:00:00+07:00

Reading time: ~15 minutes Audience: Homelabbers running 5+ Docker containers who are tired of port collisions, localhost confusion, and containers that can’t talk to each other Last tested: June 2026 — Docker 27.x, Docker Compose v2, Traefik 3.2

Introduction: The Docker Networking Trap

You started with one Docker container — maybe Pi-hole for ad blocking. You ran docker run -p 53:53 pihole/pihole and it worked. Then you added Home Assistant (-p 8123:8123), then Jellyfin (-p 8096:8096), then Portainer (-p 9443:9443). Every service got a unique port number, and you memorized them like phone extensions at a small office.

Then the problems started. Your Jellyfin container couldn’t reach your Sonarr container. Your Home Assistant couldn’t discover your MQTT broker. You tried localhost:1883 and got connection refused. You tried the container IP (172.17.0.5:1883), and it worked — until Docker restarted and assigned a new IP. The default bridge network that makes Docker feel effortless during your first docker run becomes the single biggest source of frustration the moment you have more than three containers.

This guide is about one thing: designing Docker networks that don’t rot. You will learn when to use bridge vs host vs macvlan, why user-defined bridges are the backbone of every clean Docker Compose stack, how to integrate Traefik without tangling your network topology, and how to segment containers by service role so a compromised Plex container cannot reach your Vaultwarden database.

By the end, you will have a repeatable network architecture pattern that works whether you run 5 containers on a Raspberry Pi or 50 on a Proxmox node.

Understanding Docker Network Drivers

Docker ships with five network drivers, but only three matter for a homelab. Here is what they do, when to use them, and — critically — when to avoid them.

Driver	Scope	DNS	External Access	Best For
bridge (default)	Container-to-container on same host	❌ No automatic DNS	Via port mapping (`-p`)	Nothing — avoid for multi-container setups
bridge (user-defined)	Container-to-container on same host	✅ Built-in DNS resolution	Via port mapping	The standard — every Docker Compose stack
host	Shares host network namespace	N/A (host’s DNS)	All ports exposed directly	High-performance apps (Plex transcoding, game servers)
macvlan	Container gets its own MAC/IP on LAN	N/A (LAN DHCP/DNS)	Direct LAN access	Containers needing static LAN IPs (Pi-hole, Home Assistant discovery)
overlay	Multi-host swarm	✅	Via routing mesh	Multi-node Docker Swarm (rare in homelabs)

Default Bridge: The Silent Killer

When you run docker run without explicitly specifying a network, every container lands on the default bridge network. This network has two fatal flaws for any setup with more than three containers:

No DNS resolution. Containers on the default bridge can only reach each other by IP address — and those IPs change every time a container restarts. This is why ping mysql fails while ping 172.17.0.3 works, until Docker restarts and MySQL moves to 172.17.0.6.
No isolation. Every container on the default bridge can talk to every other container. There is no segmentation, no access control, no way to say “Jellyfin can talk to Sonarr but not to Vaultwarden.”

The fix: Never use the default bridge for anything. Create a user-defined bridge network for every group of related services. We will cover this pattern in detail below.

Host Network: Raw Performance, Zero Isolation

The host driver removes Docker’s network namespace entirely. Your container sees the host’s network interfaces directly — if the host listens on 0.0.0.0:32400, the container binds to 0.0.0.0:32400. No port mapping. No NAT overhead. No Docker network proxy process sitting between your application and the network card.

When to use host networking:

Plex Media Server — transcoding benefits from direct NIC access and avoids the Docker userland proxy bottleneck.
Game servers (Minecraft, Valheim) — lower latency, no port mapping to manage.
Network monitoring tools (ntopng, Wireshark in a container) — need raw packet access.
Pi-hole with DHCP — DHCP requires broadcast traffic Docker bridge filters out.

When to avoid host networking:

Every other service. Host networking is the nuclear option. You lose DNS-based service discovery, container isolation, and port conflict detection. Two containers on host cannot both bind to port 80.

Macvlan: When Your Container Needs a LAN Identity

Macvlan gives your container a real MAC address and IP on your physical LAN, indistinguishable from a physical machine. Your router sees it. Your other devices see it. mDNS and broadcast protocols work natively.

Legitimate macvlan use cases:

Home Assistant — needs mDNS and DHCP discovery for ESPHome, Apple HomeKit, and Chromecast.
Pi-hole as primary DNS — your router expects a static LAN IP for DNS; macvlan gives Pi-hole its own 192.168.1.53.
Legacy apps that hardcode IP addresses — if some crusty service only connects to 192.168.1.100, macvlan lets you give a container that exact IP.

The macvlan caveat: A macvlan container cannot communicate with its Docker host. This is by design — macvlan isolates the container at Layer 2. If you need host-to-container communication over macvlan, you must create a sub-interface or a second macvlan on the host. For most homelabbers, the solution is simpler: only use macvlan for the one or two containers that genuinely require it, and put everything else on user-defined bridges.

The Power of User-Defined Bridge Networks

A user-defined bridge is the backbone of every well-architected Docker Compose stack. When you create a new bridge network with docker network create my-net or define a networks: block in Compose, you unlock three capabilities the default bridge cannot provide.

Automatic DNS Resolution

Containers on the same user-defined bridge can reach each other by service name or container name. This is the single feature that makes multi-container Docker viable.

# docker-compose.yml
services:
  app:
    image: my-app
    networks:
      - backend
    environment:
      - DATABASE_URL=postgres://db:5432/mydb  # ← service name, not IP

  db:
    image: postgres:16
    networks:
      - backend

networks:
  backend:
    driver: bridge

The app container connects to db:5432. Docker’s embedded DNS server resolves db to the container’s IP. No hardcoded IPs. No environment variables full of 172.x.x.x. If the db container restarts and gets a new IP, the DNS entry updates automatically. This is how every professional Docker deployment works.

Network-Level Isolation

User-defined bridges give you network segmentation at zero cost. Create one bridge per service group, and containers on different bridges cannot reach each other unless you explicitly connect them to multiple networks.

networks:
  media:       # Jellyfin, Sonarr, Radarr, Prowlarr, qBittorrent
    driver: bridge
  proxy:       # Traefik, Authelia, CrowdSec
    driver: bridge
  storage:     # Nextcloud, MariaDB, Redis
    driver: bridge
  monitoring:  # Grafana, Prometheus, Uptime Kuma
    driver: bridge
  dns:         # Pi-hole, Unbound
    driver: bridge

Why segment by service role? If a vulnerability in Jellyfin allows remote code execution, the attacker lands on the media network. From there, they can reach Sonarr and qBittorrent — annoying but not catastrophic. They cannot reach your Vaultwarden database on the storage network or your Traefik dashboard on proxy. Network segmentation turns a full-compromise scenario into a contained incident.

The trade-off: if a container genuinely needs cross-segment access (e.g., Traefik must reach every service it proxies), you attach it to multiple networks:

services:
  traefik:
    networks:
      - proxy
      - media
      - storage
      - monitoring
      - dns

Traefik is the exception, not the rule. Every other container should live on exactly one network.

The Docker Compose Default Network

When you run docker compose up, Compose automatically creates a user-defined bridge named <project>_default. Every service without an explicit networks: entry joins this network and gets DNS resolution. This is fine for a single-stack homelab with 5-8 containers. The moment you have multiple Compose files or 10+ containers, switch to explicit named networks.

Related: If you are still running containers with raw docker run commands, read our Docker Compose for Beginners guide and migrate to Compose today. You are fighting with one hand tied behind your back.

Integrating Traefik as the Network Gatekeeper

In 2026, Traefik is the standard reverse proxy for homelab Docker environments. It discovers containers via Docker socket labels, routes HTTP/HTTPS traffic, and auto-provisions Let’s Encrypt certificates — all without touching a reverse proxy GUI. But Traefik’s network architecture has specific requirements that trip up newcomers.

The Traefik Network Model

Traefik needs to be on the same Docker network as every container it proxies. This is non-negotiable: Traefik routes requests by connecting to the backend container’s internal IP via the shared Docker bridge. If Traefik is on network-A and your app is on network-B with no overlap, Traefik returns 502 Bad Gateway and nothing in the logs tells you why.

The correct pattern:

# traefik/docker-compose.yml
services:
  traefik:
    image: traefik:v3.2
    networks:
      - proxy        # Traefik's own management network
      - media        # Connects to Jellyfin/Sonarr
      - storage      # Connects to Nextcloud
      - monitoring   # Connects to Grafana/Uptime Kuma
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
    # ... rest of Traefik config

networks:
  proxy:
    external: true    # Created separately: docker network create proxy
  media:
    external: true
  storage:
    external: true
  monitoring:
    external: true

And on the application side, each service joins its functional network plus, optionally, the proxy network if you want Traefik to route to it:

# jellyfin/docker-compose.yml
services:
  jellyfin:
    image: jellyfin/jellyfin:latest
    networks:
      - media
      - proxy       # Traefik needs this to route traffic
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.jellyfin.rule=Host(`media.${DOMAIN}`)"
      - "traefik.http.services.jellyfin.loadbalancer.server.port=8096"

networks:
  media:
    external: true
  proxy:
    external: true

The golden rule: Every service Traefik proxies must either share a network with Traefik, or Traefik must be explicitly attached to that service’s network. Pick one pattern and stick with it. Most homelabbers prefer attaching Traefik to every network (the “hub” model) because it keeps application Compose files simple.

Choosing a reverse proxy? Our Traefik vs Nginx Proxy Manager vs Caddy guide breaks down which reverse proxy fits your homelab. For Docker networking specifically, Traefik has the cleanest network model because it natively understands Docker labels and service discovery.

Traefik + External Networks: Avoiding the 502

The most common Traefik networking error: you define a network in your app’s Compose file but forget to declare it as external: true. Docker Compose creates a new network with a project-prefixed name (e.g., jellyfin_media) instead of joining the existing media network. Traefik is on media, Jellyfin is on jellyfin_media, they cannot communicate, and you get 502 Bad Gateway.

Verify with:

docker network ls | grep media
# Should show ONE network named "media", not "jellyfin_media"

If you see project-prefixed duplicates, fix the Compose file to use external: true.

Network Segmentation: The Homelab DMZ Pattern

Security through network segmentation is not just for enterprises. In a homelab, the principle is simple: group containers by trust level and sensitivity, and use Docker networks as the boundary. If one segment gets compromised, the blast radius stops at the network edge.

The Five-Zone Model

Zone	Trust Level	Example Services	Network Name
Edge	Exposed to internet	Traefik, Authelia, CrowdSec	`proxy`
Public	Internet-facing apps	Nextcloud, Jellyfin, Immich	`public`
Internal	LAN-only services	Sonarr, Radarr, Home Assistant, Pi-hole	`internal`
Storage	Databases and secrets	MariaDB, PostgreSQL, Redis, Vaultwarden	`storage`
Management	Admin tools	Portainer, Uptime Kuma, Grafana, SSH	`mgmt`

Rules of engagement:

Edge can talk to everything — Traefik must route to all zones. Accept this risk and harden Traefik with Authelia SSO and rate-limiting middleware.
Public apps can talk to Storage — Nextcloud needs MariaDB. Jellyfin doesn’t need Vaultwarden. Be specific: attach only the database that app actually needs.
Internal services stay internal — Sonarr and Radarr should never be exposed to the internet. They communicate through the internal network only.
Storage is silent — No service on the storage network should have outbound internet access. Use internal: true on the network definition to block external connectivity:

networks:
  storage:
    driver: bridge
    internal: true   # Blocks all outbound internet from this network

Management is separate — Portainer and SSH containers should live on mgmt, accessible only via VPN or local LAN. Never expose Portainer’s dashboard directly to the internet, even behind Traefik with authentication.

Firewall Considerations

Docker manipulates iptables rules directly, which creates a well-known conflict: UFW or firewalld rules you write on the host are silently bypassed by Docker’s own iptables entries. Docker inserts its rules at a higher priority than user-defined rules, meaning a container bound to -p 8080:8080 is accessible on 0.0.0.0:8080 regardless of what UFW says.

The fix for UFW users:

# /etc/docker/daemon.json
{
  "iptables": false
}

Setting iptables: false tells Docker to stop manipulating iptables. You then manage all firewall rules through UFW directly. The downside: Docker’s inter-container communication and outbound NAT stop working unless you manually configure iptables rules. This is an advanced configuration — for most homelabbers, the simpler approach is binding containers to 127.0.0.1 instead of 0.0.0.0 and letting Traefik handle external access.

# Instead of this:
ports:
  - "8080:8080"

# Do this — only Traefik on the Docker network can reach it:
ports:
  - "127.0.0.1:8080:8080"

With port binding restricted to 127.0.0.1, the service is inaccessible from your LAN or the internet. Only Traefik (on the same Docker bridge) can route traffic to it. This is the single highest-impact security change you can make to a Docker homelab.

This architecture is not theoretical. It runs in production homelabs and has been battle-tested across dozens of setups. The internal: true flag on the storage network means even if an attacker escapes a container on the public zone, they cannot exfiltrate your database contents to the internet — the network simply has no route out.

Common Docker Networking Mistakes (and Fixes)

1. Using `localhost` Between Containers

The mistake:

environment:
  - DATABASE_URL=mysql://localhost:3306/mydb

Why it fails: Inside a container, localhost means the container itself. Unless MySQL is running in the same container (it should not be), localhost:3306 is an empty port.

The fix: Use the service name from your Compose file — that is what Docker’s embedded DNS resolves:

environment:
  - DATABASE_URL=mysql://db:3306/mydb

2. Exposing Ports You Don’t Need

The mistake: Every service gets ports: - "XXXX:XXXX" in Compose.

Why it fails: Each exposed port is an attack surface. A homelab with 20 services, each exposing its port to 0.0.0.0, has 20 entry points an attacker can scan and probe. Your LAN is not a trusted network — smart TVs, IoT devices, and guest Wi-Fi clients all share it.

The fix: Only Traefik should expose ports to the host. Every other service communicates over Docker networks:

# Good — only Traefik gets host ports
services:
  traefik:
    ports:
      - "80:80"
      - "443:443"

  app:
    # No ports block — Traefik routes to it via Docker network
    networks:
      - proxy

Need to see every port your homelab is exposing? Run docker ps --format 'table {{.Names}}\t{{.Ports}}' and audit every 0.0.0.0:XXXX entry. For most services, the answer is 127.0.0.1:XXXX:XXXX.

3. Forgetting `external: true` on Shared Networks

The mistake: Multiple Compose files reference the same network name without external: true. Docker Compose creates <project>_networkname networks instead of joining the shared one.

The fix: Create networks once, then reference them with external: true everywhere else:

docker network create proxy
docker network create media
docker network create storage --internal
docker network create internal
docker network create mgmt

Then in every Compose file:

networks:
  proxy:
    external: true
  media:
    external: true

4. Macvlan for Every Container

The mistake: “I want every container to have its own LAN IP so I can access them directly.”

Why it fails: Macvlan is a specialist tool. Using it for every container wastes IP addresses, breaks Docker DNS, and prevents host-container communication. Docker’s embedded DNS does not work across macvlan networks — you are back to hardcoding IPs.

The fix: Use macvlan for the one or two containers that genuinely need it (Home Assistant, Pi-hole with DHCP). Put everything else on user-defined bridges with Traefik routing.

FAQ

Q: Should I put all my containers on one network or split them into multiple networks?

Start with one user-defined bridge for everything (the Compose default). Split into separate networks when: (a) you have more than 10 containers, (b) you need to prevent specific containers from communicating, or (c) you are exposing any container directly to the internet. The five-zone model above is the target state, not the starting point.

Q: Can Traefik route to a container on a macvlan network?

No. Traefik communicates over Docker’s virtual bridge, and macvlan operates at a different layer. If a container is on macvlan, Traefik cannot reach it through Docker networking. Workaround: give the container a second interface on a user-defined bridge (Docker supports multi-network containers) and have Traefik route through that.

Q: Does Docker Compose’s network_mode: host disable all other networking?

Yes. A container with network_mode: host cannot be attached to any other Docker network. You cannot mix host networking with user-defined bridges. Choose one per container.

Q: How do I give a container a static IP on a user-defined bridge?

Docker supports static IP assignment on user-defined bridges with --subnet and per-container ipv4_address:

networks:
  custom:
    driver: bridge
    ipam:
      config:
        - subnet: 10.99.0.0/24

services:
  app:
    networks:
      custom:
        ipv4_address: 10.99.0.100

Avoid this unless you have a concrete reason — it defeats Docker’s dynamic IP management and creates a single point of configuration drift.

Q: Can containers on different Docker hosts communicate over a bridge?

Not natively. Docker bridge networks are host-local. For cross-host container communication, you need Docker Swarm with overlay networks, or a Layer 3 solution like Tailscale. For most homelabbers running on a single Proxmox node, this is a non-issue.

Q: What happens when two Compose files define the same network?

If both define it as external: true, they reference the same pre-existing network. If one defines it inline and the other uses external: true, they land on different networks and the containers cannot communicate. Consistent external: true usage across all Compose files is the solution.

Q: How do I block internet access for a specific container?

Use the internal: true flag on the network:

networks:
  no-internet:
    driver: bridge
    internal: true

Any container on this network can communicate with other containers on the same network but has no route to the internet. This is ideal for databases and sensitive services.

Conclusion: The Clean Setup Checklist

Docker networking rewards discipline. Start with the default, then migrate toward segmentation as your homelab grows. Here is the checklist for a network architecture that scales:

✅ No containers on the default bridge network — docker network inspect bridge | grep Name should return only infrastructure containers Docker itself placed there.
✅ User-defined bridges for every service group — at minimum, separate proxy, apps, and storage.
✅ Traefik is the only container exposing host ports — everything else communicates over Docker networks.
✅ Databases bound to internal: true networks — no outbound internet from your storage layer.
✅ Portainer and admin tools on mgmt, accessed via VPN — never exposed to the internet.
✅ 127.0.0.1 port bindings where possible — only Traefik needs 0.0.0.0 exposure.

If your current Docker setup looks nothing like this, do not panic. Move one service group at a time. Start by creating a proxy network and moving Traefik onto it. Next cycle, create storage and move your databases. The goal is continuous improvement, not a weekend rewrite.

The Ultimate Guide to Building Your First Homelab Server in 2026

2026-06-08T00:00:00+07:00

Starting a homelab is one of the most rewarding journeys for any tech enthusiast. Whether you are a student, a developer, or just someone who loves tinkering with technology, a homelab provides a safe, sandboxed environment to experiment with networking, server administration, containerization, and data storage.

In this guide, we will walk through the essential steps to building your first homelab server in 2026 — from choosing hardware to deploying your first Docker service — keeping cost-efficiency and modularity at the forefront.

Why Build a Homelab?

Before we dive into hardware and software, let’s define why you would want to spend time and resources on a homelab.

Learning Opportunity: There is no better way to master Linux, Docker, or Kubernetes than by running them on your own metal.
Data Privacy: By hosting your own cloud storage (Nextcloud), media server (Jellyfin), or password manager (Vaultwarden), you take control of your data away from Big Tech.
Sandbox Environment: Test new software, configurations, or CI/CD pipelines without fear of breaking your primary workstation.
Convenience: Host useful services that make your daily life easier, like ad-blockers (Pi-hole) or local dashboard aggregators (Heimdall).

1. Hardware Selection: Start Small, Grow Large

One of the biggest pitfalls for beginners is “analysis paralysis” regarding hardware. You do not need a rack-mount server to start. In fact, for most, a decommissioned office PC or a low-power Mini PC is the perfect starting point.

Recommended Entry-Level Hardware

Used SFF (Small Form Factor) Office PCs: Look for Dell OptiPlex, HP EliteDesk, or Lenovo ThinkCentre units with Intel Core i5 or i7 processors (8th gen or newer). These are power-efficient, quiet, and cost $80–200 on eBay.
Mini PCs: Devices like the Beelink SER5, Minisforum UM690, or Intel NUC offer high performance in a tiny footprint, often consuming less than 15W at idle.
Old Laptops: A laptop with a broken screen is basically a server with a built-in UPS (the battery!) and keyboard. Just keep the lid open for airflow.

Key Considerations

RAM is King: In a homelab, CPU is rarely the bottleneck; RAM is. Aim for at least 16GB. If you plan to run many virtual machines (VMs), 32GB+ is ideal.
Storage: Start with a 256GB+ SSD for your OS and main apps. Add a large mechanical HDD later for media or backups.
Power Budget: Calculate annual electricity cost: watts × 24h × 365 / 1000 × kWh_rate. A 30W server costs ~$30/year at $0.12/kWh.

2. Choosing Your Operating System (The Hypervisor)

Once you have hardware, you need an OS. For a modern homelab, a hypervisor is highly recommended, allowing you to run multiple virtual machines and containers on a single machine.

Option A: Proxmox VE (Recommended)

Proxmox is based on Debian and provides a web-based interface for managing KVM virtual machines and LXC containers. It’s free, open-source, and has an incredibly active community.

Install Proxmox on bare metal:

# 1. Download the ISO from proxmox.com
# 2. Write to USB: sudo dd if=proxmox-ve_*.iso of=/dev/sdX bs=4M status=progress
# 3. Boot from USB and follow the installer prompts
# 4. After install, access web UI at https://192.168.1.10:8006

# Switch to no-subscription repo for free updates:
sed -i 's/^deb/# deb/' /etc/apt/sources.list.d/pve-enterprise.list
echo "deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription" >> /etc/apt/sources.list
apt update && apt dist-upgrade -y

Option B: Ubuntu Server + Docker

If you prefer a simpler setup without full virtualization:

# Install Ubuntu Server 24.04 LTS
# Then install Docker:
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker $USER
newgrp docker

# Test it:
docker run hello-world

3. Essential Software Services to Install

Once your hypervisor or OS is running, here are the must-have services:

Step 1: Set Up Docker (Inside Proxmox LXC or Ubuntu)

If using Proxmox, create a privileged LXC container for Docker (nesting enabled):

pct create 100 local:vztmpl/debian-12-standard_12.7-1_amd64.tar.zst \
  --hostname docker-host \
  --storage local-lvm \
  --memory 4096 \
  --cores 2 \
  --net0 name=eth0,bridge=vmbr0,ip=dhcp \
  --features nesting=1 \
  --rootfs local-lvm:20
pct start 100
pct enter 100

Inside the container, install Docker:

curl -fsSL https://get.docker.com | sh

Step 2: Deploy Pi-hole for Network-wide Ad Blocking

docker run -d --name pihole \
  -p 53:53/tcp -p 53:53/udp -p 8081:80 \
  -v pihole_etc:/etc/pihole \
  -v pihole_dnsmasq:/etc/dnsmasq.d \
  -e WEBPASSWORD=your-admin-password \
  -e TZ=Asia/Jakarta \
  --restart unless-stopped \
  pihole/pihole:latest

Important: Set your router’s DHCP to hand out your homelab IP as the primary DNS. All devices will now be ad-free.

Step 3: Deploy Jellyfin for Media Streaming

mkdir -p ~/docker/jellyfin/{config,cache}
docker run -d --name jellyfin \
  -p 8096:8096 \
  -v ~/docker/jellyfin/config:/config \
  -v ~/docker/jellyfin/cache:/cache \
  -v /path/to/media:/media:ro \
  --device /dev/dri:/dev/dri \
  --restart unless-stopped \
  jellyfin/jellyfin:latest

Step 4: Deploy Vaultwarden (Password Manager)

docker run -d --name vaultwarden \
  -p 4743:80 \
  -v ~/docker/vaultwarden:/data \
  -e WEBSOCKET_ENABLED=true \
  -e SIGNUPS_ALLOWED=false \
  --restart unless-stopped \
  vaultwarden/server:latest

Step 5: Set Up a Dashboard (Homepage)

docker run -d --name homepage \
  -p 3002:3000 \
  -v ~/docker/homepage:/app/config \
  --restart unless-stopped \
  ghcr.io/gethomepage/homepage:latest

4. Networking and Security

A homelab without proper network hygiene can quickly become a liability.

Static IP Configuration

Assign your server a static IP in your router’s DHCP reservation (recommended) or statically configure it:

# Ubuntu/Debian Netplan
cat > /etc/netplan/01-netcfg.yaml << 'EOF'
network:
  version: 2
  ethernets:
    eth0:
      addresses:
        - 192.168.1.10/24
      routes:
        - to: default
          via: 192.168.1.1
      nameservers:
        addresses: [1.1.1.1, 8.8.8.8]
EOF
netplan apply

Firewall Basics

# UFW (Ubuntu)
ufw allow OpenSSH
ufw allow 80,443/tcp  # Reverse proxy
ufw allow 51820/udp   # WireGuard
ufw enable
ufw status verbose

Reverse Proxy

Use Nginx Proxy Manager (Docker) to route external traffic to your services with automatic SSL via Let’s Encrypt:

docker run -d --name nginx-proxy-manager \
  -p 80:80 -p 443:443 -p 81:81 \
  -v ~/docker/nginx-proxy-manager:/data \
  --restart unless-stopped \
  jc21/nginx-proxy-manager:latest

Then in the UI at http://<homelab-ip>:81, add proxy hosts pointing service.yourdomain.com to the internal Docker IPs:8096 (Jellyfin), :4743 (Vaultwarden), etc.

VPN for Remote Access

Never expose admin panels directly. Use Tailscale for zero-config secure access:

# Install Tailscale
curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up
# Open the URL, authenticate with your Google/GitHub/Microsoft account

Now access your homelab services via the Tailscale IP from any device.

5. Backups

Configure automatic backups before you need them:

# Create backup script
cat > ~/backup-homelab.sh << 'EOF'
#!/bin/bash
BACKUP_DIR="/mnt/backup"
DATE=$(date +%Y%m%d-%H%M%S)

# Back up Docker volumes
docker run --rm -v homelab_data:/data -v $BACKUP_DIR:/backup \
  alpine tar czf /backup/homelab-data-$DATE.tar.gz -C /data .

# Keep only last 14 days
find $BACKUP_DIR -name "*.tar.gz" -mtime +14 -delete
EOF
chmod +x ~/backup-homelab.sh

# Add to crontab (runs daily at 3 AM)
(crontab -l 2>/dev/null; echo "0 3 * * * /root/backup-homelab.sh") | crontab -

Conclusion

Building your first homelab is an iterative process. Start with one machine and one service. Learn how it works, how to back it up, and how to keep it updated. As your curiosity grows, so will your lab.

Here’s a quick checklist to get started: - [ ] Acquire hardware (old desktop, Mini PC, or laptop) - [ ] Install Proxmox VE or Ubuntu Server - [ ] Set up Docker - [ ] Deploy Pi-hole (ad blocking) - [ ] Deploy Jellyfin (media) or Nextcloud (files) - [ ] Configure reverse proxy (Nginx Proxy Manager) - [ ] Set up Tailscale for remote access - [ ] Configure daily backups - [ ] Join r/homelab and share your setup!

Remember: the goal is to learn and to enjoy the process. Don’t worry about having the perfect setup on day one. Happy hosting!

Mastering Proxmox Backup Server: The Essential Homelab Guide 2026

2026-06-08T00:00:00+07:00

In the evolving landscape of self-hosting and home virtualization, the importance of a reliable backup strategy cannot be overstated. As we progress through 2026, data growth and the complexity of homelab services make simple file copies insufficient. This guide explores setting up and optimizing Proxmox Backup Server (PBS) to ensure your virtualized environment remains resilient against failure — with real commands, not just theory.

Why Proxmox Backup Server (PBS)?

Traditional backup methods often involve massive full snapshots, consuming storage bandwidth and disk space rapidly. PBS changes the paradigm with:

Deduplication: Only changed blocks are stored, dramatically reducing storage requirements. A typical 100 GB VM with 2 GB daily changes uses only ~2 GB per incremental backup.
Incremental Backups: Forever-incremental architecture means the first backup is a full, and every subsequent backup is a delta — no periodic fulls needed.
Client-Side Encryption: Encrypt backups before they leave your PVE host, ensuring data is secure even if the backup storage is compromised.
Native Integration: PBS appears as a storage target directly in the Proxmox VE UI — no scripts or cron jobs required.
Verification: Automatic backup verification (CRC checksums) catches corruption before you need to restore.

Setting Up Your PBS Instance

Hardware Considerations

While PBS is resource-efficient, it benefits from fast storage for metadata:

CPU: 2-4 cores. Encryption and deduplication benefit from modern CPU extensions (AES-NI).
RAM: 4 GB minimum, 8 GB recommended. Deduplication metadata is memory-resident.
Storage: ZFS is highly recommended for data integrity. Use an SSD for the metadata volume and HDDs for bulk data.
Network: 1 Gbps minimum; 2.5+ Gbps if backing up multiple hosts simultaneously.

Step-by-Step Installation

Download the ISO from the Proxmox Backup Server download page.
Write to USB and boot the target machine.
Install via the installer — the process is identical to PVE:
Select target disk
Configure timezone and keyboard
Set root password and email
Configure static IP with hostname (FQDN format: pbs01.yourdomain.local)
Post-install: Switch to no-subscription repos:

# Comment out enterprise repo
sed -i 's/^deb/# deb/' /etc/apt/sources.list.d/pbs-enterprise.list

# Add no-subscription repo
echo "deb http://download.proxmox.com/debian/pbs bookworm pbs-no-subscription" >> /etc/apt/sources.list

# Update and reboot
apt update && apt dist-upgrade -y

Creating Your First Datastore

A datastore is a directory where PBS stores backup data. Create one via CLI:

# Create a ZFS pool for the datastore (if using a dedicated disk)
zpool create -f -o ashift=12 backup-pool /dev/sdb
zfs set compression=lz4 backup-pool

# Create the datastore directory
mkdir -p /backup-pool/datastore/main-store

# Configure it in PBS
proxmox-backup-manager datastore create main-store \
  --path /backup-pool/datastore/main-store \
  --gc-schedule "daily" \
  --verify-new \
  --verify-existing

# Check datastore status
proxmox-backup-manager datastore list

Alternatively, create the datastore via the PBS web UI: Administration → Storage → Datastore → Add.

Creating API Credentials for PVE Integration

Before connecting PVE to PBS, generate an API token:

Navigate to Configuration → Access Control → API Tokens
Create a token for user root@pam (or a dedicated backup user)
Assign the Datastore.Read and Datastore.Backup permissions
Copy the token secret immediately — it’s shown only once

Integrating PBS with Proxmox VE

Add PBS as a Storage Target

In the Proxmox VE web UI:

Go to Datacenter → Storage → Add → Proxmox Backup Server
Fill in the fields:
ID: pbs-main
Server: IP or hostname of your PBS instance
Datastore: main-store
Fingerprint: Run ssh root@pbs01.example.com "proxmox-backup-manager cert info" and copy the fingerprint
Username: root@pam (or your backup user)
Password / API Token: Paste the token secret
Click Add

Verify connectivity: The storage should appear in the Datacenter → Storage list with green status.

Configure Backup Schedule

# Create a backup job for all VMs on this node
pvesh create /cluster/backup \
  --id "daily-all" \
  --schedule "0 2 * * *" \
  --mode snapshot \
  --compress zstd \
  --storage pbs-main \
  --all 1 \
  --notes "Daily backup of all VMs to PBS"

# List configured backup jobs
pvesh get /cluster/backup

Or configure via the UI: Datacenter → Backup → Add. Set: - Schedule: 0 2 * * * (daily at 2 AM) - Mode: Snapshot (no downtime) - Compression: Zstandard (fastest) - Storage: Your PBS datastore

Restoring from a Backup

Restore a Single VM

# List available backups for a VM
proxmox-backup-client snapshot list root@pam@store1.example.com:main-store

# Restore the entire VM
# (Or do this through the PVE UI: select VM → Backup → Restore)

# Restore a single file from a backup
proxmox-backup-client restore \
  root@pam@pbs01.example.com:main-store/ct/100/2026-06-15T00:00:00Z \
  /var/lib/mysql \
  /tmp/mysql-restore

Restore via Web UI

In PVE, select the VM/CT → Backup
Choose the backup snapshot → Restore
Select target storage and node
Click Restore — the VM will be recreated from the backup

Remote Backup Sync (Offsite Strategy)

PBS supports remote sync to another PBS instance. This is essential for a 3-2-1 backup strategy:

# On the primary PBS, configure a sync job to a remote PBS
proxmox-backup-manager sync-job create \
  --remote pbs-remote.example.com \
  --remote-datastore remote-store \
  --local-datastore main-store \
  --owner root@pam \
  --schedule "0 4 * * *" \
  --transfer-last 2

This syncs only the last 2 backup snapshots to the remote site, minimizing bandwidth.

Pruning and Garbage Collection

PBS uses a two-step cleanup process:

Pruning: Removes old backup snapshots according to retention policy.

proxmox-backup-manager prune-job create \
  --datastore main-store \
  --schedule "daily" \
  --keep-last 7 \
  --keep-daily 30 \
  --keep-weekly 12 \
  --keep-monthly 12

Garbage Collection: Cleans up orphaned chunks from deduplication.

proxmox-backup-manager garbage-collection start main-store

Schedule GC via the UI: Datastore → main-store → Options → Garbage Collection: Daily.

Monitoring and Alerts

Track PBS health with the built-in notification system:

# Check datastore usage
proxmox-backup-manager datastore list

# View last verification status
proxmox-backup-manager task list

# Check systemd status
systemctl status proxmox-backup

# Monitor backup logs
journalctl -u proxmox-backup -f

Integrate PBS metrics with Grafana by exposing the API (/api2/json/admin/datastore).

Best Practices

Remote Backups (Offsite): Always have a secondary PBS instance at a different location.
Encryption: Enable client-side encryption on the PVE side — even if the remote PBS is compromised, your data stays secure.
Verify Backups: Configure verify-new and verify-existing on your datastore to catch corruption early.
Network Isolation: Run PBS in a separate VLAN or subnet. Use WireGuard/Tailscale for remote access — never expose PBS directly to the internet.
Test Restores: Schedule a quarterly restore test. A backup you’ve never restored is not a backup.
Monitor Deduplication Ratio: A ratio below 2:1 may indicate the datastore isn’t deduplicating effectively — check your VM configurations.

Troubleshooting

Backup fails with “connection refused”

Check that the PBS service is running: systemctl status proxmox-backup and that port 8007 is accessible: telnet pbs-ip 8007.

Backups are full (not incremental)

Ensure the VM has been backed up at least once. PBS is forever-incremental — every backup after the first is a delta. If backups run sequentially on different VMs, each VM independently gets incremental after its first full.

Fingerprint mismatch

Regenerate and copy the fingerprint:

# On PBS
openssl x509 -fingerprint -sha256 -noout -in /etc/proxmox-backup/proxy.pem

Conclusion

Setting up Proxmox Backup Server is the single most impactful project you can undertake for your homelab. It moves your infrastructure from “experimental” to “reliable production” status. By leveraging deduplication, encryption, and native PVE integration, you ensure that even the worst data loss scenarios are easily reversible in minutes, not hours.

Start your PBS journey today, verify your backups (not just schedule them), and enjoy the peace of mind that comes with a professional-grade recovery pipeline.

The Ultimate Self-Hosted Google Drive Alternative: Nextcloud vs Seafile vs Syncthing

2026-06-08T00:00:00+07:00

In an era where privacy is increasingly under threat and SaaS subscription costs continue to rise, taking control of your data has never been more important. For many, Google Drive, Dropbox, and OneDrive are convenient, but they come at the cost of your privacy and a monthly fee.

If you have a home server or a VPS, you can host your own file synchronization and storage solution. But with so many options available, which one should you choose? Today, we will dive deep into the three most popular self-hosted alternatives to Google Drive: Nextcloud, Seafile, and Syncthing.

Why Self-Host Your File Storage?

Before we jump into the comparisons, let’s talk about why you would want to do this in the first place:

Data Sovereignty: You are the sole owner of your files. No tech giant can scan your documents for ads or hand them over to third parties without your knowledge.
Cost Efficiency: While there is an initial cost (server hardware or VPS rent), you don’t pay a monthly subscription fee for storage capacity. If you have a terabyte of photos, you don’t need a $10/month plan; you just need a bigger hard drive.
Unlimited Speed: On your local network, file transfers can happen at the speed of your LAN—usually Gigabit or 10-Gigabit—making it much faster than downloading from a cloud provider.

1. Nextcloud: The “Everything” Solution

Nextcloud is the heavyweight champion of the self-hosting world. It’s not just a file sync solution; it’s a full-blown productivity suite.

Pros

Feature Set: Beyond file sync, you get calendars, contacts, Kanban boards, chat, video calling, and an app store with hundreds of plugins.
User Interface: It features one of the most polished web interfaces in the open-source community.
Ecosystem: There is a mobile app for almost every platform and deep integration with desktop operating systems.

Cons

Resource Heavy: Nextcloud requires significantly more RAM and CPU to run efficiently compared to the other options.
Complexity: Maintenance can be daunting. Updates occasionally break things if not managed properly.

Best For

People who want a true “Google Suite” replacement. If you want calendars, contacts, and collaborative document editing in one place, Nextcloud is the winner.

2. Seafile: The Performance King

If your primary goal is syncing files reliably and quickly, Seafile is hard to beat. It is engineered for performance.

Pros

Speed: Seafile uses a unique file-chunking system that makes it incredibly fast, especially when syncing thousands of small files.
Reliability: It is remarkably stable. It rarely crashes and handles conflicts much better than Nextcloud.
Low Overhead: It is much lighter on system resources than Nextcloud.

Cons

Limited Features: It’s a file storage solution. You don’t get integrated calendars or office document editing.
UI: The interface is functional, but lacks the “modern” feel of Nextcloud.

Best For

Users who value speed and reliability above all else. If you are a developer syncing codebases or a professional with huge file directories, Seafile is the superior choice.

3. Syncthing: The Decentralized Powerhouse

Syncthing is different. It doesn’t rely on a central server. It is a continuous decentralized file synchronization tool.

Pros

No Central Server: Files are synced directly between your devices (e.g., PC to Laptop to NAS). There is no “master” server required.
Security: Everything is encrypted in transit and at rest.
Zero Config: Once set up, it just works in the background without needing a web interface.

Cons

No Web Portal: You don’t “log in” to your server to see your files. If your PC is off, you can’t sync from it.
Advanced Networking: Since it relies on P2P, you might need to handle port forwarding or firewall settings if devices are on different networks.

Best For

People who want simple, direct file syncing between their own devices without hosting a “service” on a dedicated server.

Comparison Table

Feature	Nextcloud	Seafile	Syncthing
Type	Suite / Platform	File Sync	P2P Sync
Resources	High	Low-Medium	Very Low
Speed	Moderate	Very High	High
Remote Access	Web-based	Web-based	P2P / Direct
Extra Features	Calendar, Contacts, etc	File versioning	None

Conclusion: Which Should You Choose?

Choose Nextcloud if you are looking for a comprehensive replacement for Google Workspace or Microsoft 365.
Choose Seafile if you have heavy file sync needs and want a fast, stable, and server-based solution.
Choose Syncthing if you just want to keep folders in sync between your laptop, desktop, and phone without the overhead of maintaining a dedicated server.

Setting Up Your First Proxmox Node: A Practical Guide

2026-06-08T00:00:00+07:00

Virtualization is the heart of a modern homelab. It allows you to run dozens of services on a single physical machine, turning one server into an entire infrastructure. Proxmox Virtual Environment (PVE) is the industry-standard, open-source platform for this, combining KVM-based virtual machines with lightweight LXC containers.

This guide covers the journey from bare metal to a fully functional virtualization host with working networking, storage, and firewall configuration.

Why Proxmox?

Proxmox is built on Debian, which means it is incredibly stable. It offers: - Unified Management: One dashboard for VMs, containers, backups, and storage. - KVM & LXC: Choose full virtualization (VMs) for OS independence or containerization (LXC) for extreme performance. - Built-in Backups: Snapshot and backup scheduling without third-party tools. - High Availability: Easily expand to a cluster as your lab grows. - ZFS Support: Integrated ZFS for data integrity, compression, and snapshots.

Prerequisites

Before starting, ensure you have: 1. Hardware: A PC or server with at least 8GB of RAM and an Intel/AMD CPU supporting virtualization (VT-x or AMD-V). 2. Connectivity: Ethernet cable connected to your main switch. 3. USB Drive: At least 8GB to flash the Proxmox ISO.

Step 1: Preparing the ISO

Download the latest Proxmox VE ISO from the official download page. Use dd on Linux or a graphical tool like BalenaEtcher on Windows/macOS to write the ISO to your USB drive:

# Linux: Find your USB device first
lsblk
# Write the ISO (replace /dev/sdX with your USB device)
sudo dd if=proxmox-ve_*.iso of=/dev/sdX bs=4M status=progress
sync

Step 2: The Installation Process

Boot: Insert the USB into the target machine and boot from it via BIOS/UEFI.
Select “Install Proxmox VE” from the boot menu.
Target Disk: Choose the disk for Proxmox. Warning: This wipes all data on the target disk.
Location & Time: Set your timezone and keyboard layout.
Admin Password: Set a strong root password (use a password manager).
Email: Enter a valid email for system notifications.
Management Network: Configure your primary interface:
Hostname: Use pve01.yourdomain.local (FQDN format required)
IP Address: Choose a static IP within your LAN range (e.g., 192.168.1.10/24)
Gateway: Your router’s IP (e.g., 192.168.1.1)
DNS: 1.1.1.1, 8.8.8.8

Once installed, the system will reboot. Access the management UI at https://<YOUR_IP>:8006. Accept the self-signed certificate warning — you can replace it with a Let’s Encrypt certificate later.

Step 3: Initial Post-Install Tweaks

3.1 Configure Repositories

Proxmox includes enterprise repos by default. For homelab use, switch to the no-subscription repository:

# Comment out enterprise repo
sed -i 's/^deb/# deb/' /etc/apt/sources.list.d/pve-enterprise.list

# Add no-subscription repo
echo "deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription" >> /etc/apt/sources.list

# Update
apt update && apt dist-upgrade -y

3.2 Configure Storage

By default, Proxmox uses LVM-thin. For a homelab, ZFS is strongly recommended for data integrity, compression, and snapshots:

# Check available disks
lsblk

# Create a ZFS pool with a single disk (replace /dev/sda with your data disk)
zpool create -f -o ashift=12 tank /dev/sda

# Enable compression
zfs set compression=lz4 tank

# Create a dataset for VM storage
zfs create -o mountpoint=/tank/vm tank/vm

Then in the Proxmox Web UI: Datacenter → Storage → Add → ZFS and point it to your pool.

3.3 Network Bridge Configuration

Proxmox uses a Linux bridge (vmbr0) for VM networking. Verify your bridge configuration:

cat /etc/network/interfaces

A typical config looks like:

auto lo
iface lo inet loopback

auto enp1s0
iface enp1s0 inet manual

auto vmbr0
iface vmbr0 inet static
    address 192.168.1.10/24
    gateway 192.168.1.1
    bridge-ports enp1s0
    bridge-stp off
    bridge-fd 0

3.4 Firewall Basics

Enable the Proxmox firewall at the datacenter level:

# Enable firewall on the node
pve-firewall start
systemctl enable pve-firewall

# Check rules
pve-firewall status

In the Web UI: Datacenter → Firewall → Options → Enable: Yes. Whitelist your management IP under Datacenter → Firewall → Rules.

3.5 Remove the Subscription Nag

# Hide the subscription popup in the UI
sed -i "s/data.status !== 'Active'/false/g" /usr/share/pve-manager/js/pvemanagerlib.js
systemctl restart pveproxy

Step 4: Creating Your First Container

Before building VMs, LXC containers are lighter and ideal for Docker hosts:

# Download a Debian 12 template
pveam update
pveam download local debian-12-standard_12.7-1_amd64.tar.zst

# Create a container (CT 100, 2 cores, 4GB RAM, 20GB disk)
pct create 100 local:vztmpl/debian-12-standard_12.7-1_amd64.tar.zst \
  --hostname docker-host \
  --storage local-lvm \
  --memory 4096 \
  --cores 2 \
  --net0 name=eth0,bridge=vmbr0,ip=dhcp \
  --rootfs local-lvm:20 \
  --password your-secure-password

# Start the container
pct start 100

# Attach to its shell
pct enter 100

Step 5: Enabling Nested Virtualization

To run Docker inside an LXC container (or VMs inside a VM), enable nesting:

# For a specific container
echo "features: nesting=1" >> /etc/pve/lxc/100.conf

# Or via command line
pct set 100 --features nesting=1

# Restart the container
pct restart 100

Troubleshooting

Web UI not loading

Check that pveproxy is running: systemctl status pveproxy. Restart with systemctl restart pveproxy.

VMs fail to start with “KVM acceleration not available”

Ensure virtualization is enabled in BIOS. Check with:

egrep -c '(vmx|svm)' /proc/cpuinfo

If it returns 0, reboot into BIOS and enable Intel VT-x or AMD SVM.

No network in container

Ensure the bridge is configured correctly and STP is disabled:

bridge link show
brctl show vmbr0

Conclusion

You now have a fully functional Proxmox node with ZFS storage, firewall protection, and a running LXC container. The next logical steps are: 1. Deploy Docker inside your LXC container 2. Set up a reverse proxy (like Nginx Proxy Manager) 3. Configure automated backups to a Proxmox Backup Server

Remember: always set up automated backups for your VMs in Datacenter → Backup before running production workloads.

Self-Hosted Backup Strategy for Homelab 2026: The Complete 3-2-1 Guide with Restic, Kopia & Duplicati

Self-Hosted Backup Strategy for Homelab 2026: The Complete 3-2-1 Guide with Restic, Kopia & Duplicati

Reading time: ~18 minutes Audience: Homelab owners who have never tested a restore — and everyone who has data they cannot afford to lose

Introduction: The Most Common Homelab Regret

Go to any r/homelab or r/selfhosted thread titled “What do you wish you had done sooner?” and the top-voted answer is always the same: backups. Not VLAN segmentation. Not Kubernetes. Not 10 GbE networking. Backups.

The pattern is painfully consistent. A self-hoster spends months building a beautiful homelab — Proxmox hypervisor, Docker Compose stacks for Nextcloud, Jellyfin, Home Assistant, Pi-hole, Vaultwarden. Everything hums. Then one morning the boot SSD fails. Or a bad Docker volume mount overwrites a database. Or ransomware encrypts the media share. And there is no backup. Months of configuration, family photos, and carefully curated media libraries — gone.

The goal of this guide is simple: make sure that is never you. By the end, you will have a production-ready 3-2-1 backup strategy running in Docker Compose, covering your Docker volumes, Proxmox VMs, databases, and configuration files — with automated scheduling, encrypted offsite copies, and actual restore testing.

Already running Proxmox? See our Proxmox Beginner Guide if you need to set up your hypervisor first. New to Docker? Start with Nginx Proxy Manager Docker Compose for the compose fundamentals.

Why Every Homelab Needs a Backup Strategy (Now, Not Later)

Before we talk tools, let us talk about what failure actually looks like in a homelab:

Failure Scenario	What You Lose	Recovery Without Backup
Boot SSD corruption	All VM configs, Docker volumes, OS	Rebuild from scratch (days to weeks)
RAID controller failure	Media library, documents	Re-rip/re-download (months)
Accidental `rm -rf /mnt/data`	Everything on that mount	Zero — it is gone
Ransomware encrypts NFS share	All files accessible to compromised container	Pay ransom or lose everything
Failed Docker update destroys volume	Application data, databases	Rebuild app, lose all state
Proxmox node hardware failure	All VMs on that node	Rebuild every VM manually

The common thread: without backups, every one of these scenarios requires a full rebuild. With a proper 3-2-1 backup strategy, recovery takes hours — not weeks.

The Hidden Cost of NOT Backing Up

It is easy to think “I don’t have anything worth backing up — I can re-download my media and rebuild my configs.” Let us quantify that:

Configuration files: A typical homelab has 20–40 Docker Compose files, each with environment variables, volume mounts, and network configurations tested over weeks. Rebuilding them from scratch takes 10–20 hours.
Databases: Your Nextcloud database contains file metadata, shares, calendars, and contacts. Your Vaultwarden database holds every password. Rebuilding without a backup means starting over.
Media libraries: Even if you can re-download, a 4 TB media library takes weeks on a typical residential connection. And many items may no longer be available.
Family photos and documents: These are irreplaceable. A backup is the only insurance policy.

Understanding the 3-2-1 Backup Rule for Homelabs

The 3-2-1 rule is the gold standard of backup strategy, and it is deceptively simple:

Layer	Rule	What It Means for Your Homelab
3	Three copies of your data	Primary data + local backup + offsite backup
2	Two different storage media	Don’t put both backups on the same NAS or same disk type
1	One offsite copy	Geographically separate — cloud, VPS, or a friend’s house

Why Each Layer Matters

Three copies protects against single-point-of-failure. If your primary data lives on one server and your backup lives on another — and both are the only copies — a fire or flood that takes both eliminates your data forever. Three copies gives you a buffer.

Two different media protects against correlated failures. If your primary data and backup both live on the same NAS with the same RAID array, a RAID controller failure or filesystem corruption can destroy both simultaneously. Different media means: primary on SSD, backup on HDD; or primary on NAS, backup on external USB drive.

One offsite copy protects against physical disasters. Fire, flood, theft, lightning strike — anything that destroys your physical location. An offsite copy in the cloud, on a VPS in another city, or even at a family member’s house ensures your data survives a worst-case scenario.

Common Mistakes That Break the 3-2-1 Rule

Same-disk “backup”: Copying files to another folder on the same drive is not a backup. If the drive fails, both copies die.
Live mirroring without versioning: A real-time mirror (RAID 1, rsync mirror, ZFS replication) is not a backup — it is redundancy. If ransomware encrypts the primary, it encrypts the mirror too. You need versioned, point-in-time snapshots.
Never testing restores: A backup you have never restored is Schrödinger’s backup — it might work, or it might be a collection of corrupted files. You do not know until you test.
No encryption on offsite copies: If your offsite backup lives on a cloud provider or a VPS, and it is not encrypted, anyone with access to that storage can read your data. Always encrypt before it leaves your network.

What to Back Up in a Homelab

Not everything in your homelab needs the same backup frequency or retention. Here is the practical checklist:

Backup Priority Checklist

Priority	Data Type	Examples	Frequency	Retention
🔴 Critical	Databases, passwords	Vaultwarden DB, Nextcloud DB, config files	Daily	90 days
🔴 Critical	Docker Compose files	`docker-compose.yml`, `.env` files	Daily (git)	Forever
🟡 Important	Docker volumes	Nextcloud data, Home Assistant config, Immich uploads	Daily	60 days
🟡 Important	VM disk images	Proxmox VM backups (PBS)	Weekly	30 days
🟢 Nice-to-have	Media libraries	Jellyfin/Plex media	Weekly	30–60 days
🟢 Nice-to-have	ISO images, templates	Proxmox ISOs, Docker images	Monthly	Keep latest

What NOT to Back Up

Docker images: These can be re-pulled from registries. Backing them up wastes space.
Transient caches: /tmp, browser caches, thumbnail caches.
Downloadable media: If you can re-download it quickly and it is not personal, skip it.

Pro tip: Store your Docker Compose files in a git repository. Push to Forgejo or GitHub after every change. This gives you infinite version history for free and is your first line of defense against misconfiguration.

The Big Three Self-Hosted Backup Tools: Restic vs Kopia vs Duplicati

The homelab backup tool landscape in 2026 has three clear leaders. Each excels in different scenarios. Here is the objective comparison:

Feature Comparison Matrix

Learning curve	🔴 Steep (CLI)	🟡 Moderate (GUI)	🟢 Easy (GUI)

Restic — The Command-Line Powerhouse

Restic is the tool of choice for technical users who want maximum control, efficiency, and reliability. It is written in Go, uses content-defined chunking for excellent deduplication, and supports virtually every storage backend.

Best for: Technical users comfortable with CLI, automation via cron, S3/B2 offsite backups, large datasets where deduplication matters.

Docker Compose snippet (scheduled backup with prune):

# docker-compose.yml — Restic scheduled backup
version: "3.8"
services:
  restic-backup:
    image: restic/restic:latest
    container_name: restic-backup
    environment:
      - RESTIC_REPOSITORY=s3:s3.amazonaws.com/bucket-name
      - RESTIC_PASSWORD=${RESTIC_PASSWORD}
      - AWS_ACCESS_KEY_ID=${AWS_ACCESS_KEY_ID}
      - AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY}
    volumes:
      - /opt/docker:/data:ro          # Docker volumes to back up
      - /etc/restic:/restic-config    # Exclude files, policy config
    entrypoint: ["/bin/sh", "-c"]
    command:
      - |
        restic backup /data \
          --exclude-file=/restic-config/excludes.txt \
          --tag docker-volumes \
          && restic forget --keep-daily 7 --keep-weekly 4 --keep-monthly 3 --prune \
          && restic check
    restart: unless-stopped

Kopia — The Modern GUI-Friendly Option

Kopia is the newest entrant and has rapidly gained traction because of its polished web UI, advanced snapshot policies, and multi-repository support. If you want a GUI to browse snapshots and restore individual files without remembering CLI flags, Kopia is the answer.

Best for: Users who want a web UI, complex retention policies per dataset, graphical snapshot browsing, multi-repo management.

Docker Compose snippet (Kopia server mode with web UI):

# docker-compose.yml — Kopia server with web UI
version: "3.8"
services:
  kopia:
    image: kopia/kopia:latest
    container_name: kopia-server
    hostname: kopia
    environment:
      - KOPIA_PASSWORD=${KOPIA_PASSWORD}
      - USER=kopia
    ports:
      - "51515:51515"
    volumes:
      - ./kopia-config:/app/config
      - ./kopia-cache:/app/cache
      - /opt/docker:/data:ro
      - /mnt/backup-nas:/backup-local
    command:
      - server
      - start
      - --insecure
      - --address=0.0.0.0:51515
      - --server-username=kopia
      - --server-password=${KOPIA_PASSWORD}
    restart: unless-stopped

Duplicati — The Beginner’s Choice

Duplicati is the easiest to set up: a single Docker container with a web UI, a setup wizard, and support for dozens of backends out of the box. It is the “install in 5 minutes and forget about it” option.

Best for: Beginners, quick setup, diverse backend support, users who want a familiar GUI wizard.

Docker Compose snippet (LinuxServer Duplicati):

# docker-compose.yml — Duplicati with web UI
version: "3.8"
services:
  duplicati:
    image: lscr.io/linuxserver/duplicati:latest
    container_name: duplicati
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Asia/Jakarta
      - CLI_ARGS=
    volumes:
      - ./duplicati-config:/config
      - /opt/docker:/source:ro
      - /mnt/backup-nas:/backup
    ports:
      - "8200:8200"
    restart: unless-stopped

Which one should you choose? If you are comfortable with CLI, pick Restic. If you want a GUI without sacrificing performance, pick Kopia. If you are new and want the easiest path, start with Duplicati and consider migrating to Restic or Kopia as your needs grow.

Building Your 3-2-1 Homelab Backup Stack

Now let us assemble the complete stack, layer by layer.

Layer 1 — Primary Data (Your Production Environment)

This is where your data lives: - Docker host: /opt/docker with all Compose files and volumes - Proxmox host: VM disk images on local-lvm or ZFS - NAS: Media library, document shares, ISO storage

Layer 2 — Local Backup (On-Site, Different Media)

Your first backup copy should live on different physical hardware:

Option	Cost	Capacity	Complexity
External USB HDD (8–20 TB)	$150–$400	High	Low
Dedicated backup NAS (used)	$200–$500	High	Medium
Proxmox Backup Server (PBS)	$0 (software) + HW	Configurable	Medium
Old PC with TrueNAS	$0–$200	High	Medium
Raspberry Pi + SATA HAT + HDD	$80–$200	1–8 TB	Medium

NFS mount for NAS backup target (add to /etc/fstab):

# /etc/fstab — Mount NAS share for backup target
192.168.50.100:/mnt/tank/backups  /mnt/backup-nas  nfs  rw,hard,intr,noatime  0  0

Layer 3 — Offsite Backup (Geographically Separate)

Your third copy must be physically separate from your homelab. Here are the best options for self-hosters in 2026:

Provider	Type	Free Tier	Paid From	Best For
Backblaze B2	S3-compatible object storage	10 GB	$6/TB/month	Restic/Kopia S3 target
Cloudflare R2	S3-compatible object storage	10 GB	$0.015/GB/month	Zero egress fees
Hetzner StorageBox	SFTP/rsync/Borg	—	€3.81/month for 1 TB	Simple rsync target
BuyVM + Slab	VPS + attached storage	—	$5/month for 256 GB	Self-hosted offsite node
Hetzner CX22 VPS	VPS with 1 TB block storage	—	~€6/month	Self-hosted backup server

Restic S3 repository configuration (Backblaze B2 example):

# Set up a new Restic repository on Backblaze B2
export RESTIC_REPOSITORY="s3:s3.us-west-004.backblazeb2.com/homelab-backups"
export RESTIC_PASSWORD="your-strong-password-here"
export AWS_ACCESS_KEY_ID="your-b2-key-id"
export AWS_SECRET_ACCESS_KEY="your-b2-application-key"

restic init

Rsync to Hetzner StorageBox script:

#!/bin/bash
# rsync-backup.sh — Backup docker volumes to Hetzner StorageBox via rsync
STORAGEBOX="u123456@u123456.your-storagebox.de"
REMOTE_PATH="/home/backups/docker"
LOCAL_PATH="/opt/docker"
LOG_FILE="/var/log/backup-rsync.log"

echo "[$(date)] Starting rsync backup to StorageBox..." >> "$LOG_FILE"
rsync -avz --delete \
    --exclude="*.log" \
    --exclude="cache/" \
    "$LOCAL_PATH/" "$STORAGEBOX:$REMOTE_PATH/" \
    >> "$LOG_FILE" 2>&1

if [ $? -eq 0 ]; then
    echo "[$(date)] Backup completed successfully." >> "$LOG_FILE"
else
    echo "[$(date)] Backup failed with exit code $?" >> "$LOG_FILE"
    # Send notification (ntfy, Discord, email — see monitoring section)
fi

Proxmox-Specific Backup Strategy

If you run Proxmox as your hypervisor, you have two additional backup paths:

Proxmox Backup Server (PBS)

PBS is a dedicated backup appliance (free, open-source) that provides incremental, deduplicated VM and container backups with a web UI. It is purpose-built for Proxmox and handles dirty-bitmap incremental backups — meaning after the first full backup, subsequent backups only transfer changed blocks.

PBS Docker Compose (for running PBS as a container on a backup node):

# docker-compose.yml — Proxmox Backup Server
version: "3.8"
services:
  pbs:
    image: ayufan/proxmox-backup-server:latest
    container_name: pbs
    hostname: pbs
    network_mode: host
    privileged: true
    volumes:
      - ./pbs-config:/etc/proxmox-backup
      - ./pbs-datastore:/backup-datastore
      - ./pbs-logs:/var/log/proxmox-backup
    restart: unless-stopped

VM Backup Schedule Recommendations

VM Type	Backup Method	Frequency	Retention
Critical VMs (firewall, DNS)	PBS + Restic to offsite	Daily	30 days
Application VMs (Nextcloud, Vaultwarden)	PBS	Daily	30 days
Development VMs	PBS	Weekly	14 days
Media server VMs	PBS	Weekly	14 days

Testing Your Backups (The Step Everyone Skips)

A backup you have never restored is not a backup — it is a hope. Every backup tool can produce corrupted output if disk errors, memory faults, or software bugs intervene.

The Quarterly Backup Fire Drill

Once every three months, run this checklist:

Pick a random backup snapshot — do not pick the most recent one, pick one from 30 days ago. This tests your retention policies and ensures older snapshots are not silently corrupted.
Restore to a test directory — never restore over production data.
Verify file integrity — compare checksums with the original if possible.
Start the restored application — spin up a Docker container from the restored config and verify it works.
Document the result — a simple log entry: “2026-06-07: restored Nextcloud backup from 2026-05-07. All files verified. Database started successfully.”

Restic restore test script:

#!/bin/bash
# test-restore.sh — Restore a random snapshot to /tmp and verify
SNAPSHOT=$(restic snapshots --json | jq -r '.[-5].id')  # 5th newest
RESTORE_DIR="/tmp/restic-restore-test-$(date +%Y%m%d)"

echo "Testing restore of snapshot: $SNAPSHOT"
mkdir -p "$RESTORE_DIR"
restic restore "$SNAPSHOT" --target "$RESTORE_DIR"

if [ $? -eq 0 ]; then
    echo "✅ Restore successful. Files in: $RESTORE_DIR"
    echo "📊 File count: $(find "$RESTORE_DIR" -type f | wc -l)"
    echo "📊 Total size: $(du -sh "$RESTORE_DIR" | cut -f1)"
else
    echo "❌ Restore FAILED. Check restic logs immediately."
fi

Disaster Recovery Scenarios

Let us walk through five real disaster scenarios and how your 3-2-1 strategy handles each:

Scenario	RTO (Recovery Time)	RPO (Data Loss)	Recovery Path
Primary server SSD failure	2–4 hours	0–24 hours	Restore Docker volumes from local NAS backup. Rebuild OS from Ansible/Terraform.
Ransomware encrypts everything	4–8 hours	0–24 hours	Wipe infected systems. Restore from air-gapped or versioned backup. Offsite copy must be immutable or pull-only.
NAS hardware failure	1–2 days (if replacing HW)	0 hours	All primary data on Docker host unaffected. Restore NAS from offsite backup or PBS.
Offsite provider goes down	0 hours (no data loss)	N/A	Set up new offsite target. Push fresh backup. Meanwhile, local backup still protects you.
Accidental deletion (30 days ago)	1–2 hours	0 (if versioned)	Browse versioned snapshots. Restore the specific file or directory from before the deletion.

RTO (Recovery Time Objective): How long it takes to recover. RPO (Recovery Point Objective): How much data you can afford to lose (measured in time).

Security & Encryption Best Practices

Backups contain your most sensitive data — passwords, personal documents, family photos. Every backup copy, especially offsite copies, must be encrypted.

Encryption Checklist

Layer	Requirement	Tool
At rest (local)	Encrypt backup target disk	LUKS, ZFS native encryption
In transit	Encrypt network traffic	TLS (Restic/Kopia), SSH (rsync), WireGuard/Tailscale
At rest (offsite)	Encrypt backup data before it leaves	Restic/Kopia built-in encryption
Key management	Store encryption keys separately from data	Password manager, offline paper backup
Key backup	Ensure keys are recoverable	Printed QR code of encryption key in a safe deposit box or with a trusted person

Immutable Backups for Ransomware Protection

Restic supports append-only repositories when using the REST server backend. Kopia supports object lock with S3-compatible storage. This means even if an attacker compromises your backup server, they cannot delete or modify existing snapshots — they can only add new ones, and only until the lock expires.

Cost Comparison: Building a Backup Stack on a Budget

You can build a working 3-2-1 backup strategy at almost any budget level:

Tier	Monthly Cost	What You Get	Safety Level
$0	Free	Local backup to spare USB HDD. Manual offsite rotation to a drive stored at work/family.	🟡 Low (manual, no automation)
$5	~$5/month	Hetzner StorageBox 1 TB + local USB HDD. Automated rsync or Restic.	🟢 Good for configs + databases
$15	~$15/month	Backblaze B2 2 TB + local backup + PBS. Fully automated 3-2-1.	🟢 Excellent for most homelabs
$50	~$50/month	Dedicated backup VPS + cloud storage + local NAS. Multi-site automated.	🔵 Enterprise-grade redundancy

The sweet spot for most homelabs: $5–$15/month. A Hetzner StorageBox (€3.81 for 1 TB) for offsite, a spare USB HDD for local backup, and Restic (free) for automation gives you a fully automated 3-2-1 setup for under $5/month.

Maintenance & Monitoring

A backup strategy is not “set and forget.” It requires monitoring to catch failures before you need a restore.

Backup Health Dashboard with Uptime Kuma

Monitor each backup job with Uptime Kuma push monitors. If a job does not report in within its expected window, you get an alert:

#!/bin/bash
# backup-health-check.sh — Run after each backup job
BACKUP_NAME="docker-restic-daily"
KUMA_PUSH_URL="https://uptime.yourdomain.com/api/push/abc123?status=up&msg=OK"

# ... backup commands here ...

if [ $? -eq 0 ]; then
    curl -s "$KUMA_PUSH_URL&msg=Backup+${BACKUP_NAME}+completed+successfully"
else
    curl -s "${KUMA_PUSH_URL}&status=down&msg=Backup+${BACKUP_NAME}+FAILED"
fi

Full monitoring setup: See our Uptime Kuma Docker Compose guide for the complete deployment and notification configuration.

Monthly Backup Health Check Routine

[ ] Review backup logs for errors and warnings
[ ] Check disk usage trends (are backups growing unexpectedly?)
[ ] Verify retention policies are pruning old snapshots
[ ] Run a spot restore test on one random file
[ ] Verify offsite copy is reachable and up to date
[ ] Rotate encryption key backup if keys have changed

Which Backup Tool Should You Choose? Decision Matrix

Your Profile	Recommended Tool	Why
“I just want it to work — I’m new”	Duplicati	Web UI wizard, 5-minute setup, broad backend support
“I live in the terminal”	Restic	Fastest, most mature, best S3 support, excellent dedup
“I want a GUI + power”	Kopia	Web UI with advanced policies, snapshot browsing, multi-repo
“I only backup Proxmox VMs”	Proxmox Backup Server	Purpose-built, dirty-bitmap incremental, web UI
“I need versioned file-level backup with dedup”	Restic or BorgBackup	Both excellent; Restic has better cloud/S3 support
“I backup to NAS only, no cloud”	Kopia (server mode)	Web UI, local repository, snapshot policies
“I want zero-knowledge cloud backup”	Restic	Client-side encryption, all cloud providers supported

The Beginner Path

Start with Duplicati (easiest setup, web UI wizard). Once you understand backup concepts — snapshots, retention, deduplication — migrate to Kopia or Restic for better performance and reliability.

The Power User Path

Start with Restic from day one. The CLI learning curve is worth it for the performance, reliability, and flexibility. Use the shell scripts in this guide as templates.

Conclusion: Start With ONE Backup Today

The most important backup is the one you actually run. Do not let analysis paralysis stop you from taking the first step. Here is a concrete 15-minute action plan:

Right now: Copy your Docker Compose files to a git repository and push. This is zero-cost and protects your most valuable configuration data immediately.
Today: Plug in a spare external HDD and run a manual restic backup of /opt/docker. One command: restic init --repo /mnt/backup && restic backup /opt/docker.
This week: Set up the Docker Compose configuration from this guide (Restic, Kopia, or Duplicati — pick one). Schedule it via cron or the tool’s built-in scheduler.
This month: Add an offsite target. A Hetzner StorageBox costs €3.81/month and gives you a true 3-2-1 strategy.
This quarter: Run your first restore test. Pick a random snapshot and restore it to /tmp. Verify the files are intact.

Your future self — the one who accidentally deletes the wrong directory, survives a hardware failure, or faces a ransomware attack — will thank you.

Traefik vs Nginx Proxy Manager vs Caddy for Homelab 2026: The Reverse Proxy Decision Guide

Reading time: ~16 minutes Audience: Homelab owners choosing their first reverse proxy, or migrating from one to another Last tested: June 2026 — Traefik 3.2, Nginx Proxy Manager 2.12, Caddy 2.8

Introduction: The Homelab Reverse Proxy Problem

You have fifteen Docker containers running in your homelab — Nextcloud on port 8080, Pi-hole on port 8180, Plex on port 32400, Home Assistant on port 8123. Your browser autocomplete is a graveyard of 192.168.1.50:XXXX entries, your family refuses to type port numbers, and half your services scream “Not Secure” because you never set up HTTPS. There is a single piece of software that fixes all of this at once: a reverse proxy.

A reverse proxy sits at the edge of your network, receives every incoming HTTP request on standard ports 80 and 443, inspects the domain name in the request header, and routes traffic to the correct backend container. You go from memorizing ports to typing photos.homelab.local, admin.homelab.local, and dash.homelab.local. Every service gets automatic HTTPS via Let’s Encrypt. Your browser lock icon turns green. Your family stops asking why the website looks broken.

But here is the problem: in 2026, there are three dominant reverse proxies in the homelab space — Traefik, Nginx Proxy Manager, and Caddy — and they serve fundamentally different audiences. Pick wrong, and you spend weeks fighting configuration files that feel designed by people who hate you. Pick right, and your reverse proxy becomes the most reliable piece of your infrastructure.

This guide compares all three head-to-head with copy-paste Docker Compose configs, a detailed comparison matrix, a decision tree for five common homelab scenarios, Cloudflare Tunnel integration, and Proxmox deployment notes — everything updated for 2026.

Meet the Three Contenders

Traefik — The Kubernetes-Native Powerhouse

Traefik is the Swiss Army knife of reverse proxies. It was purpose-built for container-native environments: it discovers services automatically by watching Docker socket events or Kubernetes API endpoints. You spin up a new container with the label traefik.http.routers.app.rule=Host("app.example.com") and Traefik wires it into the routing table without a config file edit or a reload.

Why homelabbers love it: Automatic service discovery means zero manual proxy-host configuration. A dashboard at traefik.example.com shows every router, service, and middleware in real time. Middleware chains — rate limiting, IP whitelisting, basic auth, redirect regex — stack like LEGO blocks. Traefik 3.x added Gateway API support, HTTP/3 (QUIC), and OpenTelemetry tracing.

Why homelabbers curse it: The learning curve is real. Traefik has three configuration layers (static, dynamic, and Docker labels) and the documentation assumes you already understand reverse proxy theory. A misplaced YAML indent or a forgotten entrypoints definition produces silent failures. The dashboard is read-only by default — you cannot add a route through the GUI. If you need a GUI for proxy-host management, Traefik is not your tool.

Best for: Advanced users who run 10+ containers, want automatic discovery, and are comfortable with YAML-first configuration. If you already use Portainer or Komodo to manage container stacks, Traefik pairs naturally.

Nginx Proxy Manager — The GUI-First Beginner’s Choice

Nginx Proxy Manager (NPM) wraps the battle-tested Nginx engine in a clean, intuitive web GUI. You open http://your-ip:81, log in, click “Add Proxy Host,” fill in domain name, backend IP:port, toggle “Block Common Exploits,” and click “SSL” to request a Let’s Encrypt certificate. That is the entire workflow. No config files. No YAML. No CLI.

Why homelabbers love it: The barrier to entry is near-zero. If you can fill out a web form, you can run NPM. The GUI shows every proxy host with a green/red status indicator. Let’s Encrypt certificate renewal is fully automatic. Access lists let you add HTTP basic auth to specific hosts with a few clicks. NPM 2.12 added HTTP/2 push support, improved WebSocket handling, and a dark mode for the admin panel.

Why homelabbers curse it: The GUI is the only management interface — there is no API, no IaC path, and no config-as-code workflow. If your NPM database gets corrupted, you must rebuild every proxy host by hand (unless you backed up the SQLite file). Custom Nginx directives require dropping into the “Advanced” tab and writing raw Nginx config — eliminating the GUI’s simplicity advantage. No native Docker socket integration or automatic service discovery.

Best for: Beginners who want a working reverse proxy in 15 minutes. Homelabbers with fewer than 15 services who prefer clicking to typing. Anyone migrating from a manual Nginx setup who wants a GUI wrapper around the same engine they already trust.

Already running NPM? See our dedicated beginner guide: Nginx Proxy Manager Docker Compose

Caddy — The Zero-Config HTTPS Contender

Caddy is the developer-friendly reverse proxy that ships with automatic HTTPS by default. You write a three-line Caddyfile:

app.example.com {
    reverse_proxy localhost:8080
}

Caddy obtains a Let’s Encrypt certificate on first launch and renews it silently forever. No certificate settings. No cron jobs. No “SSL” tab to click. It just works. Caddy 2.8 added HTTP/3 support, improved reverse proxy health checks, and a new caddy adapt command for validating configs before reload.

Why homelabbers love it: The configuration syntax is the cleanest of the three. A Caddyfile reads like pseudocode. Zero SSL configuration overhead. Built-in support for the ACME DNS-01 challenge (needed for wildcard certificates and services behind Cloudflare). The caddy-docker-proxy module adds Docker label-based routing similar to Traefik but with Caddy’s simpler syntax.

Why homelabbers curse it: The plugin ecosystem, while growing, is smaller than Nginx’s. Some advanced features — rate limiting, failover, request transformation — require compiling Caddy with non-standard modules using xcaddy. The official Docker image is minimal; adding plugins requires a custom build step in your Dockerfile or using a community image. No native GUI. The Caddyfile syntax, while clean, is unlike any other reverse proxy config format.

Best for: Users who want the simplest possible HTTPS setup. Developers who value clean configuration syntax. Homelabbers who run fewer than 10 services and want a “set and forget” reverse proxy that handles certificates without human intervention.

Decision Tree: Which Reverse Proxy Should You Choose?

Answer these five questions in order. The first “yes” you hit is your recommendation.

Scenario 1: “I just want HTTPS on my services. I don’t care about Docker labels, APIs, or advanced routing. Give me a GUI.”

→ Pick Nginx Proxy Manager. You will be up and running in 15 minutes. The GUI eliminates YAML entirely. Everything is point-and-click.

Scenario 2: “I run 15+ containers, add new ones every week, and I want my reverse proxy to detect new services automatically without manual host creation.”

→ Pick Traefik. Docker label-based auto-discovery means you configure routing inside each container’s docker-compose.yml and Traefik picks it up without a reload. No GUI bottleneck.

Scenario 3: “I hate YAML and I hate GUIs. I want the cleanest possible config syntax and I never want to think about SSL certificates again.”

→ Pick Caddy. The Caddyfile syntax is the most readable of any reverse proxy. Automatic HTTPS is truly zero-config — no toggle, no checkbox, no cron job. It just happens.

Scenario 4: “I need advanced routing — sticky sessions, circuit breakers, rate limiting, IP whitelisting, traffic splitting — and I’m comfortable with config files.”

→ Pick Traefik or Caddy, depending on your tolerance for YAML. Traefik has a richer built-in middleware catalog. Caddy requires plugins for some advanced features but the config syntax is easier to maintain long-term. If your routing logic spans multiple conditions, Traefik’s router/middleware/service separation is cleaner.

Scenario 5: “I want to manage my reverse proxy config in Git, review changes in pull requests, and deploy via CI/CD.”

→ Pick Traefik. Its YAML configuration files are Git-ops friendly. You can store traefik.yml and dynamic.yml in version control, review routing changes before deployment, and use Git history to roll back misconfigurations. Caddy’s Caddyfile also works in Git-ops flows, but Traefik’s separation of static and dynamic config gives finer control. NPM has no config-as-code path.

Docker Compose: All Three Side by Side

All three reverse proxies can be deployed in under 5 minutes with these minimal Compose files. Customize the .env variables before starting.

Proxmox Deployment Notes

All three reverse proxies run cleanly inside Proxmox LXC containers or VMs. Here are the deployment specifics for homelab users running Proxmox 8.x:

Setup	Traefik	NPM	Caddy
Recommended Proxmox host	LXC (privileged, nesting=1) or VM	LXC (any) or VM	LXC (any) or VM
Docker inside LXC	Requires `features: nesting=1`	Same	Same
Best practice	Dedicated LXC container, 2 vCPU, 2 GB RAM	Dedicated LXC, 1 vCPU, 1 GB RAM	Dedicated LXC, 1 vCPU, 512 MB RAM
Port 80/443 access	Forward from router to Proxmox host IP	Forward from router to host IP	Forward from router to host IP
Proxmox firewall	Allow ports 80, 443 inbound	Allow ports 80, 443, 81 inbound	Allow ports 80, 443 inbound

Setting up Proxmox first? Follow our Proxmox Beginner Guide before deploying a reverse proxy container.

All three reverse proxies benefit from being the only service listening on ports 80 and 443 on the Proxmox host. If you run multiple reverse proxies or services that bind to these ports, use macvlan or ipvlan Docker networks to assign dedicated IPs.

Cloudflare Tunnel Integration

Pairing a reverse proxy with Cloudflare Tunnel gives you secure remote access without opening ports 80/443 on your router. This is ideal if you are behind CGNAT or prefer not to expose your home IP.

Architecture

Internet → Cloudflare Edge → cloudflared tunnel → localhost:8080 → Reverse Proxy → Docker backend

The reverse proxy receives requests on an internal port (e.g., 8080) instead of binding directly to 80/443. Cloudflare Tunnel’s cloudflared daemon connects to Cloudflare’s edge and forwards traffic to localhost:8080, which Traefik/NPM/Caddy listens on.

Minimal cloudflared config (config.yml):

tunnel: YOUR-TUNNEL-ID
credentials-file: /etc/cloudflared/credentials.json

ingress:
  - hostname: "*.yourdomain.com"
    service: http://reverse-proxy:80
  - service: http_status:404

Complete Cloudflare Tunnel setup: See our Cloudflare Tunnel Homelab Guide for the full walkthrough, including Tunnel creation, DNS configuration, and security hardening.

Traefik + Cloudflare Tunnel specifics

Traefik needs to trust the X-Forwarded-* headers sent by Cloudflare. Add the following to your traefik.yml:

entryPoints:
  websecure:
    address: ":443"
    forwardedHeaders:
      trustedIPs:
        - "173.245.48.0/20"   # Cloudflare IP ranges
        - "103.21.244.0/22"
        - "103.22.200.0/22"
        # Full list at https://www.cloudflare.com/ips/

Performance Benchmarks (Estimated)

These numbers are approximate, derived from community benchmarks on Reddit r/selfhosted and the Caddy vs Traefik vs Nginx comparison threads. Your mileage will vary based on hardware, backend latency, and TLS configuration.

Metric	Traefik 3.2	NPM 2.12 (Nginx)	Caddy 2.8
Requests/sec (static file, 1KB)	~18,000	~28,000	~25,000
Requests/sec (proxy to backend, 1KB)	~12,000	~18,000	~16,000
TLS handshake latency (new)	~12 ms	~8 ms	~10 ms
Idle RAM	~40 MB	~25 MB	~20 MB
Under load RAM (1,000 req/s)	~120 MB	~80 MB	~60 MB
Configuration reload time	<50 ms (hot)	<100 ms (reloads Nginx)	<30 ms (graceful)

Key takeaway: NPM (backed by Nginx) is the raw throughput champion for homelab workloads. Caddy is close behind with less RAM. Traefik trades some throughput for its dynamic discovery features. For a homelab serving family traffic — not a SaaS product with 10,000 concurrent users — any of the three will saturate your gigabit LAN before the reverse proxy becomes the bottleneck.

FAQ: Common Reverse Proxy Questions

Do I need a reverse proxy if I only have three services?

Yes — for HTTPS alone. Without a reverse proxy, you must configure TLS on each service individually. With one, you configure it once. Even for three services, the time savings justify the setup.

Can I run two reverse proxies at the same time?

Technically yes, but avoid it. Two reverse proxies competing for ports 80/443 create routing headaches. Pick one reverse proxy and route all traffic through it. If you need a second (e.g., Traefik for Docker services and NPM for non-Docker services), use a dedicated IP per proxy via macvlan.

Which reverse proxy is best for WebSocket-heavy services (Home Assistant, Uptime Kuma, code-server)?

All three handle WebSockets natively with minimal configuration. Traefik and Caddy detect and proxy WebSocket upgrades automatically. NPM requires toggling the “WebSockets Support” switch in the GUI for each proxy host.

How do I monitor reverse proxy health?

Traefik: Built-in Prometheus metrics endpoint at /metrics. Pair with Grafana for dashboards.
NPM: No native metrics. Monitor via container health checks and HTTP status probes.
Caddy: Built-in Prometheus metrics with the caddy-http-prometheus plugin.

For general uptime monitoring of your services behind the proxy, add Uptime Kuma to your Docker stack.

Final Recommendation

You are…	Use…	Because…
A beginner with 3-10 services	Nginx Proxy Manager	GUI eliminates the learning curve. You’ll be online in 15 minutes.
An intermediate tinkerer who values simplicity	Caddy	Cleanest config syntax. Automatic HTTPS with zero effort.
An advanced homelabber with 15+ containers and automation	Traefik	Auto-discovery and config-as-code scale with your infrastructure.
Someone who wants Git-ops / CI/CD for config	Traefik	YAML configs are version-control friendly.
Someone who never wants to edit a text file	Nginx Proxy Manager	GUI-only workflow.
Someone who wants the absolute lightest resource footprint	Caddy	20 MB idle RAM.

There is no single “best” reverse proxy for everyone. The correct choice depends on how many services you run, how much you value automation versus simplicity, and whether you prefer clicking buttons or editing config files. All three are production-grade, actively maintained, and power thousands of homelabs in 2026.

SteadyPub recommendation: Start with Nginx Proxy Manager if you are new to reverse proxies. Graduate to Traefik once you have 15+ containers and want automatic discovery. Use Caddy if you value clean config syntax and truly zero-touch HTTPS above all else.

Uptime Kuma Docker Compose Setup for Homelab 2026: Monitor Every Service

2026-06-07T00:00:00+07:00

Uptime Kuma Docker Compose Setup for Homelab 2026: Monitor Every Service

Reading time: ~14 minutes Audience: Homelab owners who want to know when their services go down — before their family tells them

Introduction: The “Who Watches the Watcher” Problem

Your homelab runs twenty Docker containers. Nextcloud holds your family photos. Jellyfin streams your media library. Pi-hole filters your DNS. Home Assistant controls your lights. And at 2 AM, while you are asleep, one of them silently crashes — and you find out at breakfast when your partner asks why the media server is broken again.

This is the fundamental monitoring problem every homelab owner faces: you cannot fix what you do not know is broken.

Uptime Kuma is the solution. It is a free, open-source, self-hosted uptime monitoring tool with a beautiful web dashboard, multi-channel notifications, public status pages, and support for HTTP, TCP, DNS, Ping, Docker, and Push monitors. It runs in a single Docker container, consumes under 100 MB of RAM, and can monitor fifty services from a Raspberry Pi. And in 2026, with version 1.x mature and feature-complete, it is the undisputed king of self-hosted uptime monitoring.

But deploying Uptime Kuma is only half the battle. The real question is: who watches the watcher? If Uptime Kuma itself goes down — because your Docker host rebooted, your Proxmox node crashed, or your ISP dropped the connection — all your monitoring goes dark and you will never know. This guide covers that too, with the Healthchecks.io “watch the watcher” pattern that gives you a dead man’s switch for your monitoring stack.

By the end of this guide, you will have: a production-ready Uptime Kuma deployment via Docker Compose, five real monitors watching your actual homelab services, Telegram and Discord notifications, a public-facing status page behind your reverse proxy, and a Healthchecks.io heartbeat that alerts you if Uptime Kuma itself dies. No other guide covers all of this in 2026.

Why Uptime Kuma in a Homelab?

Before you deploy anything, it helps to understand what Uptime Kuma is — and what it is not. The homelab monitoring landscape has several tools, and choosing the wrong one wastes hours.

Uptime Kuma vs. the Alternatives

Feature	Uptime Kuma	UptimeRobot (Free)	Prometheus + Alertmanager	Grafana OnCall
Self-hosted	✅ Yes	❌ SaaS only	✅ Yes	✅ Yes
Setup time	~10 minutes	~5 minutes	~2 hours	~1 hour
Status pages	✅ Built-in	✅ Built-in	❌ Needs Grafana	❌ No
Push monitors	✅ Yes	❌ No	✅ Pushgateway	✅ Yes
Docker monitoring	✅ Native	❌ No	✅ cAdvisor	❌ No
GUI dashboard	✅ Beautiful	✅ Simple	❌ CLI/config only	✅ Grafana
Notification channels	60+	5 (free tier)	10+	10+
Resource usage	~80 MB RAM	N/A (SaaS)	~2 GB RAM	~500 MB RAM
Learning curve	Low	Low	High	Medium

When to choose Uptime Kuma: You want a dead-simple, beautiful uptime dashboard that takes 10 minutes to deploy and immediately tells you which services are up or down. You need built-in status pages, push monitors for cron jobs, and dozens of notification channels — without writing a single line of PromQL.

When to pair it with Prometheus and Grafana: Uptime is a binary signal — up or down. It does not tell you why your service is slow, which database query is eating CPU, or when your disk will fill up. For that, you want metrics. The two tools complement each other perfectly: Uptime Kuma for “is it alive?” and Grafana + Prometheus for “how healthy is it?”

Resource requirements: Uptime Kuma runs comfortably on a Raspberry Pi 4, an Intel N100 mini PC, or any Docker host with 512 MB of free RAM. The database (SQLite) stays small — under 200 MB even with hundreds of monitors and months of history.

What You’ll Need

Hardware Requirements

Component	Minimum	Recommended
CPU	1 core (ARM or x86)	2 cores
RAM	256 MB free	512 MB free
Disk	500 MB	2 GB (for history)
Network	Any	Dedicated VLAN for monitoring traffic

Software Prerequisites

Docker Engine 24.x+ and Docker Compose v2+
A Linux host — any distribution that runs Docker (Debian 12, Ubuntu 24.04, Proxmox LXC, Raspberry Pi OS)
Optional but recommended: a reverse proxy (Nginx Proxy Manager or Traefik) for HTTPS access
Optional: a Cloudflare Tunnel if you want to expose your status page publicly without opening ports

Services You Will Monitor

This guide assumes you have at least five homelab services running. Examples used throughout:

Nextcloud — HTTP monitor on port 8443
Jellyfin — HTTP monitor on port 8096
Pi-hole — DNS monitor on port 53
Portainer — HTTP monitor on port 9443
Home Assistant — HTTP monitor on port 8123

If you do not have these specific services, the monitor types and configuration patterns apply to any service in your stack.

Project Structure

Create a clean directory for Uptime Kuma. Keeping it alongside your other Docker Compose stacks makes backups straightforward.

~/docker/uptime-kuma/
├── docker-compose.yml
├── .env
└── data/          (auto-created by Docker)

The data/ directory holds the SQLite database, uploaded monitor screenshots, and notification credentials. Back this up.

The Docker Compose Configuration

`docker-compose.yml`

This is the production-ready Compose file. It pins the Uptime Kuma version (not latest), mounts a persistent volume, sets resource limits, and includes a healthcheck so Docker itself knows whether the container is healthy.

Why version 1 and not latest? Pinning to the major version (1) means you get patch updates (1.23.x) automatically without risking a breaking v2 migration. When Uptime Kuma v2 is released, you will evaluate the changelog before upgrading — not wake up to a broken monitoring stack.

`.env` File

# Uptime Kuma
TZ=Asia/Jakarta

Keep it simple. The timezone ensures all timestamps, maintenance windows, and notification schedules align with your local time.

Optional: Docker Socket for Container Monitoring

If you want Uptime Kuma to monitor Docker containers directly (checking container health status from the Docker daemon), mount the Docker socket as read-only:

    volumes:
      - ./data:/app/data
      - /var/run/docker.sock:/var/run/docker.sock:ro

Security note: Mounting the Docker socket gives the container access to the Docker API. In a homelab this is generally acceptable, but understand the trade-off: any process with access to docker.sock can start, stop, or inspect any container on the host.

Step-by-Step Installation

Step 1: Create the Project Directory and Files

mkdir -p ~/docker/uptime-kuma
cd ~/docker/uptime-kuma

# Create the .env file
echo "TZ=Asia/Jakarta" > .env

# Create docker-compose.yml with the content above
nano docker-compose.yml

Step 2: Start the Container

docker compose up -d

Verify it is running:

docker compose ps
# Should show uptime-kuma as "Up" and "(healthy)"

Step 3: Complete First-Run Setup

Open http://<your-server-ip>:3001 in your browser. The first-run wizard asks you to:

Create an admin account — username, password (use a password manager — you will not log in often, but losing this account means losing access to your monitoring dashboard)
Enable 2FA (optional but recommended if your dashboard is accessible outside your LAN) — Uptime Kuma supports TOTP-based two-factor authentication
Set a custom page title — call it “Homelab Status” or your domain name

Missing your server IP? If you deployed on Proxmox, use the container/LXC IP. If on bare metal, use ip addr show to find it.

Step 4: Add Your First Monitor

Click “Add New Monitor” and fill in:

Field	Example Value	Notes
Monitor Type	HTTP(s)	Most homelab services use HTTP
Friendly Name	Nextcloud	Display name on your dashboard
URL	`https://nextcloud.homelab.local`	Full URL, including `https://`
Heartbeat Interval	60 seconds	60s is fine for most services
Retries	3	Avoids false positives from transient blips
Resend Notification	0 (every down event)	You want to know every time it goes down
Max Redirects	0	Most homelab services should not redirect
Accepted Status Codes	200	Optional; tighten to expected codes

Click Save. The monitor appears on your dashboard. It runs its first check within 60 seconds. A green heart means your service is reachable. A red heart means it is not — and if you have configured notifications, you will know immediately.

Step 5: Configure Notification Channels

A monitor without an alert is a log entry you will never read. Uptime Kuma supports over 60 notification channels. Here are the four most useful for homelab owners:

Channel	Best For	Setup Complexity
Telegram	Instant push notifications to your phone	Low — needs bot token + chat ID
Discord	Sharing alerts with a homelab community or family server	Low — needs webhook URL
Email (SMTP)	Reliable fallback when chat services are down	Medium — needs SMTP server credentials
ntfy	Self-hosted push notifications, zero reliance on third parties	Medium — needs ntfy server URL + topic

Setting up Telegram:

Message @BotFather on Telegram and create a bot with /newbot
Copy the bot token (looks like 123456:ABC-DEF1234ghikl...)
Send a message to your bot, then visit https://api.telegram.org/bot<TOKEN>/getUpdates to find your chat ID
In Uptime Kuma: Settings → Notifications → Setup Notification → Telegram
Paste the bot token and chat ID, click Test, and confirm you receive the test message

Setting up Discord:

In your Discord server: Server Settings → Integrations → Webhooks → New Webhook
Copy the webhook URL (looks like https://discord.com/api/webhooks/...)
In Uptime Kuma: Settings → Notifications → Setup Notification → Discord
Paste the webhook URL, click Test

Step 6: Create a Public Status Page

A public status page lets your family (or users, if you share services) check the health of your homelab without accessing the admin dashboard. It is a read-only, beautifully branded page you can host at status.yourdomain.com.

Settings → Status Page → New Status Page
Give it a name and a slug (e.g., homelab)
Pick which monitors appear — select the services your family cares about (Jellyfin, Home Assistant) but not internal-only ones (database, Docker socket)
Customize the footer with your domain, a logo, and a custom message (“Having trouble? Message me on Signal.”)
Copy the generated URL slug. If reverse proxy is configured, this becomes https://status.yourdomain.com

No reverse proxy yet? The status page URL will be http://<server-ip>:3001/status/homelab. Jump to the Reverse Proxy Integration section to make it accessible at a clean domain with HTTPS.

Step 7: Add Maintenance Windows

When you take Jellyfin down to add a new hard drive, you do not want Uptime Kuma spamming notifications. Maintenance windows suppress alerts on a schedule.

Settings → Maintenance → Add Maintenance Window, select the affected monitors, set the start/end time, and save. Notifications pause during the window but uptime checks continue — so you can see the downtime in your history without the noise.

Monitor Types & Decision Matrix

Uptime Kuma supports eight monitor types. Choosing the right one for each service is the difference between meaningful alerts and noise.

Monitor Type	Protocol	Best For	Example
HTTP(s)	HTTP/HTTPS GET	Web services, APIs, dashboards	Nextcloud, Portainer, Jellyfin
TCP	Raw TCP connect	Databases, game servers, mail servers	MySQL (3306), Minecraft (25565), SMTP (25)
Ping	ICMP Echo	Network devices, bare-metal servers	Router (192.168.1.1), NAS, managed switch
DNS	DNS query	DNS servers, ad-blockers	Pi-hole (query `google.com` against 192.168.1.2:53)
Docker	Docker socket API	Container health checks	Any container with a healthcheck defined in its Compose file
Push	Inbound HTTP (passive)	Cron jobs, backup scripts	Nightly `borg backup` script pushes a heartbeat when it completes
MQTT	MQTT topic	IoT devices, sensor data	Temperature sensor publishes to `homelab/sensors/temp`
gRPC	gRPC health check	Microservices	Custom gRPC health probe endpoints

Decision Matrix: Which Monitor for Which Service?

Your Service	Use This Monitor	Why
Web app (Nextcloud, Jellyfin, Portainer, Home Assistant)	HTTP(s)	Verifies the web server responds with the expected status code
Database (PostgreSQL, MySQL, Redis)	TCP	Confirms the port is open and accepting connections without needing to authenticate
Router, switch, access point	Ping	Simplest network-layer check — does the device respond to ICMP?
Pi-hole, AdGuard Home, Unbound	DNS	Verifies DNS resolution works, not just that port 53 is open
Docker container with healthcheck	Docker	Reads container health status directly from Docker daemon — more accurate than a port check
Nightly backup script, log rotation cron	Push	The script calls a unique Uptime Kuma URL after success; if the URL is not called within the window, Uptime Kuma alerts
MQTT sensor (Zigbee2MQTT, ESPHome)	MQTT	Watches for a heartbeat message on a topic

Reverse Proxy Integration

Accessing Uptime Kuma on http://192.168.1.50:3001 works — until your browser marks it “Not Secure” and refuses to save your password. A reverse proxy gives you https://uptime.yourdomain.com with automatic SSL.

Option 1: Nginx Proxy Manager

If you already use Nginx Proxy Manager, this takes 30 seconds:

Log into NPM at https://npm.yourdomain.com:81
Hosts → Proxy Hosts → Add Proxy Host
Fill in:
Domain Names: uptime.yourdomain.com
Forward Hostname / IP: uptime-kuma (the container name, if on the same Docker network) or 192.168.1.50
Forward Port: 3001
Websocket Support: ✅ Enable (Uptime Kuma uses WebSockets for real-time dashboard updates)
SSL tab → select “Request a new SSL Certificate,” check “Force SSL” and “HTTP/2 Support”
Click Save

Your dashboard is now at https://uptime.yourdomain.com with a valid Let’s Encrypt certificate.

For the status page, add a second proxy host: status.yourdomain.com → same backend (uptime-kuma:3001). In Uptime Kuma, configure the status page slug to homelab. Visitors to https://status.yourdomain.com see a dedicated read-only status page.

Option 2: Traefik

If you use Traefik, add these labels to your docker-compose.yml:

    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.uptimekuma.rule=Host(`uptime.yourdomain.com`)"
      - "traefik.http.routers.uptimekuma.entrypoints=websecure"
      - "traefik.http.routers.uptimekuma.tls.certresolver=letsencrypt"
      - "traefik.http.services.uptimekuma.loadbalancer.server.port=3001"

The dashboard appears at https://uptime.yourdomain.com with automatic TLS.

Option 3: Cloudflare Tunnel (Zero Port Forwarding)

If you do not want to open any ports on your router, use a Cloudflare Tunnel to expose the status page publicly. Add this ingress rule to your config.yml:

ingress:
  - hostname: status.yourdomain.com
    service: http://uptime-kuma:3001
  - service: http_status:404

Security tip: Only expose the status page (status.yourdomain.com), not the admin dashboard (uptime.yourdomain.com). Add a Cloudflare Access policy to the admin dashboard subdomain for an extra authentication layer.

“Watch the Watcher” — Healthchecks.io Integration

Here is the problem with self-hosted monitoring: when your Docker host crashes, Uptime Kuma crashes with it. You get no alert because the tool that sends alerts is also dead. This is the “who watches the watcher” problem, and the solution is a dead man’s switch.

Healthchecks.io is a free service (open-source, self-hostable) that expects a periodic HTTP request — a heartbeat — from your monitored service. If the heartbeat does not arrive within a configured grace period, Healthchecks.io sends you an alert. It works even when your entire homelab is offline because Healthchecks.io runs outside your infrastructure.

Setup (5 Minutes)

Create a free Healthchecks.io account at healthchecks.io — the free tier includes 20 checks
Create a new check → name it “Uptime Kuma Heartbeat,” set grace period to 5 minutes, set schedule to “/5 * * * ” (every 5 minutes)
Copy the Ping URL — it looks like https://hc-ping.com/<uuid>

The Heartbeat Cron Job

On a secondary device — a VPS, a Raspberry Pi Zero, or even your always-on desktop — create a cron job that hits the Uptime Kuma health endpoint:

# Run every 5 minutes — verifies Uptime Kuma is responding
*/5 * * * * curl -s -o /dev/null -w "%{http_code}" https://uptime.yourdomain.com/api/status-page/heartbeat/homelab | grep -q "200" && curl -fsS -o /dev/null https://hc-ping.com/<uuid>

What this does:

Every 5 minutes, the cron job hits your Uptime Kuma status page API
If the response is HTTP 200 (Uptime Kuma is alive), it pings Healthchecks.io
If the response is anything else (Uptime Kuma is down or unreachable), Healthchecks.io receives no ping
Healthchecks.io waits the 5-minute grace period, then sends you an alert via email, Telegram, Discord, or any of its dozen notification channels

The key is running this cron job outside the infrastructure Uptime Kuma is monitoring. If your homelab loses power, the VPS that runs this cron job is unaffected, and you get the alert.

Self-hosting Healthchecks.io: You can deploy your own instance via Docker Compose. See the Healthchecks.io Docker deployment guide for the Compose file. This keeps everything self-hosted while the watcher sits on a separate VPS or a friend’s homelab.

Updating & Maintenance

How to Update Uptime Kuma

Uptime Kuma releases frequently. Updating is a two-command process:

cd ~/docker/uptime-kuma
docker compose pull       # Pull the latest 1.x image
docker compose up -d      # Recreate the container with the new image

Uptime Kuma runs database migrations automatically on startup. The process takes under 10 seconds and your monitor history is preserved.

Backup Strategy

The entire state of Uptime Kuma — monitors, notifications, status pages, settings — lives in ./data/kuma.db (the SQLite database). Back this up.

Simple backup with tar:

# Run this before updates or on a cron schedule
tar -czf uptime-kuma-backup-$(date +%Y%m%d).tar.gz ~/docker/uptime-kuma/data/

Restore:

cd ~/docker/uptime-kuma
docker compose down
tar -xzf uptime-kuma-backup-20260607.tar.gz -C /
docker compose up -d

Version Pinning Policy

Strategy	Example	When to Use
`louislam/uptime-kuma:1`	Auto-updates within v1.x	Production homelab — stable, gets patches
`louislam/uptime-kuma:latest`	Always the newest release	Testing/lab only — may include breaking changes
`louislam/uptime-kuma:1.23.13`	Exact version pin	Mission-critical deployments — full control

The :1 tag used in this guide is the sweet spot: you get security patches and bug fixes automatically, but you will never wake up to a v2 migration without opting in.

Troubleshooting Common Issues

Monitors Show “Down” but the Service is Actually Reachable

Likely cause: Network isolation. Uptime Kuma runs in a Docker container with its own network namespace. If your monitored services are on a different Docker network, VLAN, or host interface, Uptime Kuma cannot reach them.

Fix: Ensure Uptime Kuma is on the same Docker network as the monitored services, or use the host’s IP address (192.168.1.50) instead of localhost or container names.

# Add Uptime Kuma to your existing proxy/traefik network
networks:
  - proxy_network

networks:
  proxy_network:
    external: true

Notifications Not Firing

Click “Test” on the notification configuration — if the test fails, the credentials are wrong
Check the monitor’s notification assignment — a monitor must have at least one notification channel assigned in its settings
Check rate limits — Telegram limits bots to ~30 messages/second; Discord has per-webhook rate limits. If you have 50 monitors all going down simultaneously, some notifications may be throttled
Verify the notification condition — by default, Uptime Kuma notifies on every status change. If you have “Resend Notification” set to a high number, you may be waiting for the resend interval

Status Page Not Loading Publicly

Reverse proxy misconfiguration — the status page URL in Uptime Kuma must match the external URL. In Settings → Status Page, the “Domain” field should be https://status.yourdomain.com
WebSocket blocked — status pages use WebSockets for live updates. If your reverse proxy strips WebSocket headers, the page loads but never updates. Enable WebSocket support in NPM or Traefik
Cloudflare proxy cache — if you proxy through Cloudflare (orange cloud), ensure the status page subdomain has caching disabled (set to “Bypass” in Page Rules)

High CPU Usage

Uptime Kuma normally consumes under 1% CPU. If you see sustained CPU spikes:

Too many monitors on too short an interval — 200 HTTP monitors at 20-second intervals is 600 requests/minute. Increase the interval to 60 or 120 seconds
Certificate expiry checks on all monitors — this is a host-level integration, not per-monitor. Enable it once in Settings → Monitoring → “Certificate Expiry Notification”
Browser dashboard open 24/7 — the dashboard uses WebSockets and real-time chart rendering. Close the browser tab when not actively monitoring

FAQ

Q: Can Uptime Kuma monitor services on another VLAN?

Yes, as long as the Docker host can route to that VLAN. If your Docker host sits on the management VLAN (192.168.1.0/24) and your IoT VLAN is 192.168.100.0/24, Uptime Kuma can monitor devices on the IoT VLAN — provided inter-VLAN routing is allowed. See our homelab networking guide for VLAN setup.

Q: How many monitors can I run on a Raspberry Pi 4?

Approximately 200 monitors at 60-second intervals before you notice CPU impact. Uptime Kuma is remarkably lightweight — each HTTP check is a single fetch() call.

Q: Does Uptime Kuma support SNMP for switch monitoring?

Not natively as of version 1.x. For SNMP monitoring of managed switches, pair Uptime Kuma with Prometheus + SNMP Exporter. Use Uptime Kuma’s Ping monitor for basic switch reachability.

Q: Can I run Uptime Kuma behind Authelia or Authentik SSO?

Yes. Place the SSO middleware in your reverse proxy layer, not in Uptime Kuma itself. In NPM, configure a custom location that requires Authelia authentication before proxying to port 3001. In Traefik, add the traefik.http.routers.uptimekuma.middlewares=authelia@file label.

Q: What is the difference between Uptime Kuma and Prometheus?

Uptime Kuma tells you if a service is up. Prometheus tells you how the service is performing. They answer different questions. Uptime Kuma is binary (up/down) and lightweight. Prometheus collects numeric metrics (CPU usage, request latency, disk I/O) over time and requires more resources. The two work together — Uptime Kuma for immediate outage detection, Prometheus for capacity planning and performance optimization.

Q: How do I monitor my VPS from my homelab?

Add a TCP monitor for SSH (port 22) and an HTTP(s) monitor for any web services running on the VPS. If the VPS has a public domain, monitor https://status.yourdomain.com from your homelab’s Uptime Kuma. For the reverse — monitoring your homelab from your VPS — run a second Uptime Kuma instance on the VPS or use the Healthchecks.io pattern described above.

Conclusion & Next Steps

You now have a production-ready Uptime Kuma deployment that monitors your entire homelab, alerts you via Telegram or Discord when something breaks, shows a public status page your family can check, and keeps itself honest with a Healthchecks.io dead man’s switch.

What to do next:

Add more monitors — every service in your docker-compose.yml should have a corresponding monitor in Uptime Kuma
Set up a dashboard TV — plug a cheap tablet or old monitor into a Raspberry Pi, open Uptime Kuma in full-screen kiosk mode, and mount it on the wall. Instant homelab nerve center
Pair with metrics — deploy Grafana and Prometheus for deep performance dashboards; Uptime Kuma handles “is it up?”, Grafana handles “is it healthy?”
Add a second Healthchecks.io check — monitor the health of your reverse proxy, your router, and your ISP connection. A five-minute cron job on a $5 VPS can tell you the difference between “Jellyfin crashed” and “your internet is down”
Review your notification channels — during a real outage at 3 AM, which channel will actually wake you up? Configure at least two channels (Telegram + Email) for critical services

The homelab monitoring journey does not end here — it starts here. Every new service you deploy should come with the question: “How will I know when this breaks?” And now you have the answer.

What service will you monitor first?

Best NAS OS for Homelab 2026: TrueNAS vs Unraid vs OpenMediaVault vs Synology

2026-06-06T14:00:00+07:00

Reading time: ~16 minutes Audience: Homelab owners looking to build or buy a NAS for centralized storage Prerequisites: Basic familiarity with Linux and self-hosting concepts

Why Your Homelab Needs a NAS

If you run a homelab with Docker containers, virtual machines, or media servers, centralized storage is not optional — it is the backbone of your setup. A dedicated NAS (Network Attached Storage) operating system gives you:

One pool of storage that every container, VM, and client on your network can access — no more juggling USB drives or resizing virtual disks.
Data redundancy through RAID, ZFS mirrors, or parity arrays so a single drive failure does not wipe out your Plex library, Nextcloud files, or Immich photo archive.
Snapshot and backup capabilities built into the OS itself — schedule hourly snapshots, replicate to a second box, or push encrypted backups to Backblaze B2.
App hosting on the NAS itself — most NAS OS options today ship with Docker or Kubernetes support, so you can run your services directly on the storage box.

Without a NAS, every self-hosted app becomes its own storage island. With a NAS, your Docker Compose stacks mount shared volumes, your Proxmox VMs pull disk images from NFS shares, and your self-hosted apps all read and write to the same redundant pool.

The question is not whether you need a NAS. The question is: which NAS operating system fits your homelab?

The 4 Best NAS Options for Homelab in 2026

The NAS software landscape in 2026 has consolidated around four dominant options — two free and open-source, one paid with a generous one-time license, and one turnkey hardware-plus-software bundle. Here is the landscape at a glance:

Option	Cost	License	Storage Tech	Best For
TrueNAS 26 (SCALE)	Free	Open Source (BSD)	ZFS pools	Data integrity purists, matched drives
Unraid 7.3	$59–129 (one-time)	Proprietary + OSS	Parity array + ZFS optional	Flexible builders, mixed drive sizes
OpenMediaVault 7	Free	Open Source (GPLv3)	mdadm/LVM + ZFS plugin	Lightweight setups, old hardware, ARM
Synology DSM 7.2	$200+ (hardware)	Proprietary	SHR/Btrfs	Users who want zero setup and polish

Each of these can run Docker containers, share files over SMB/NFS, and serve as the storage backbone for your homelab. The differences lie in how they protect your data, how much hardware they need, and how steep the learning curve is. Let us examine each in detail.

TrueNAS 26 (Free)

TrueNAS is the heavyweight champion of data integrity. The latest release — TrueNAS 26 (replacing the previous TrueNAS SCALE 24.10 branding) — runs on Debian and uses OpenZFS as its storage engine. ZFS is what sets TrueNAS apart: every block of data is checksummed, so if a drive silently corrupts a file (bit rot), ZFS detects and repairs it automatically. No other filesystem in this comparison offers that level of protection at the filesystem level.

Key features:

OpenZFS 2.3+ — snapshots, replication, inline compression, deduplication, and self-healing
Docker/Apps via Kubernetes — the Apps system uses Helm charts under the hood, with a catalog of 100+ pre-configured apps (Plex, Jellyfin, Immich, Nextcloud)
Built-in SMB, NFS, iSCSI — enterprise-grade sharing out of the box
Web UI with real-time reporting — disk health, pool usage, network throughput, CPU/RAM graphs

Hardware requirements: TrueNAS is the hungriest option. You need at least 8 GB of RAM (ZFS uses RAM as a read cache called ARC), and 16 GB+ is recommended for production use. ECC RAM is strongly recommended — not because ZFS demands it, but because ZFS’s self-healing guarantees weaken if a memory error corrupts data in-flight before ZFS can checksum it. Storage-wise, ZFS pools require matched drives: all drives in a vdev should be the same size, and expanding a pool typically requires adding an entire new vdev rather than a single drive.

Best for: Users who want the strongest data integrity guarantees, are willing to invest in proper hardware, and plan their storage capacity upfront.

Pros: - Best-in-class data integrity with ZFS checksums and self-healing - Free and open source — no license keys, no subscription - Active development — iXsystems releases regular updates with new features - Enterprise heritage — same ZFS engine used in data centers worldwide - Built-in replication to a second TrueNAS box for off-site backup

Cons: - High RAM requirement — 8 GB minimum, 16 GB+ recommended for usable ARC - Inflexible pool expansion — adding a single drive to an existing pool is not straightforward - Steep learning curve — ZFS concepts (vdevs, pools, datasets, ARC) take time to master - Kubernetes-based Apps are more complex than plain Docker Compose — some homelab users prefer the simplicity of docker-compose.yml

Unraid 7.3 ($59–129 One-Time)

Unraid takes the opposite philosophy: flexibility over rigidity. Instead of ZFS pools, Unraid uses a proprietary parity-protected array where any mix of drives — 4 TB, 8 TB, 14 TB, different brands and speeds — can coexist in the same array. You designate one or two drives as parity drives, and Unraid calculates parity data so any single (or dual, with two parity drives) drive failure is recoverable. The parity drive must be at least as large as your largest data drive.

Unraid 7.3 (released May 2026) is the latest stable release, and it has added optional ZFS support — you can now create ZFS pools alongside the traditional Unraid array, giving you the best of both worlds if you have matched drives for ZFS and mismatched drives for the main array.

Key features:

Mixed drive array — throw in any SATA/NVMe drives you have; Unraid handles the parity math
Community Applications (CA) plugin — arguably the best Docker app ecosystem of any NAS OS. One-click install for over 2,000 apps, from Plex to Home Assistant to Paperless-ngx
Native Docker + Docker Compose — no Kubernetes wrapper; just plain Docker with a friendly GUI
GPU passthrough — assign a GPU to a VM or Docker container for hardware transcoding or AI inference
VM manager — run Windows, Linux, or macOS VMs with passed-through hardware

Hardware requirements: Unraid is lighter than TrueNAS. 4 GB of RAM is the minimum, and 8–16 GB is comfortable for most homelab use. ECC is nice but entirely optional. Because Unraid reads data from individual drives (not striping across all drives like RAID-Z), only the drive hosting the requested file spins up — the rest can stay idle, saving power.

Pricing tiers (one-time purchase, lifetime updates):

Tier	Price	Max Attached Devices
Basic	$59	6
Plus	$89	12
Pro	$129	Unlimited

Best for: Homelab builders who acquire drives gradually, want the easiest Docker experience, or need GPU passthrough for media transcoding and AI workloads.

Pros: - Mix any drive sizes — gradually upgrade by swapping smaller drives for larger ones - Best Docker app ecosystem — Community Applications plugin is unmatched in ease of use - One-time payment, lifetime updates — no subscription trap - GPU passthrough for transcoding and AI — excellent Plex/Jellyfin host - Optional ZFS support in v7.3+ for users who want ZFS pools alongside the array

Cons: - No native bit rot protection on the parity array — ZFS is better for long-term archival - Parity array write speed is slower than ZFS (writes require reading parity + data + writing parity) - Paid license — though the one-time cost is reasonable for what you get - Boots from a USB flash drive — which can fail without warning if you use a cheap stick

OpenMediaVault 7 (Free)

OpenMediaVault (OMV) is the lightweight, runs-on-anything NAS OS. Built on Debian 12 (Bookworm), OMV 7 is the current stable release, with OMV 8 expected later in 2026 based on Debian 13 (Trixie). OMV does not force you into a specific storage technology — it supports mdadm (Linux software RAID), LVM, and Btrfs natively, with an optional ZFS plugin (via the OMV-extras repository).

OMV’s philosophy is minimalism: install a bare Debian system, add the OMV packages, and manage everything through a clean web interface. It consumes far fewer resources than TrueNAS or Unraid, making it ideal for repurposed hardware.

Key features:

mdadm RAID — traditional Linux software RAID (0, 1, 5, 6, 10) with grow and reshape support
ZFS plugin (via OMV-extras) — ZFS pools with a web UI for snapshot and dataset management
Docker and Portainer plugin — install Portainer from the web UI and manage containers there
SMB, NFS, FTP, Rsync, TFTP — all standard file-sharing protocols
Plugin system — additional services (Syncthing, UrBackup, SnapRAID, mergerfs) installable from the web UI

Hardware requirements: OMV is the lightest option. It runs comfortably on: - 1 GB RAM (2 GB+ recommended for ZFS) - Any x86-64 CPU or ARM (Raspberry Pi 4/5, Odroid, RockPro64) - A USB flash drive or SD card for the OS + SATA/NVMe drives for data

Best for: Beginners, users with old or low-power hardware, Raspberry Pi enthusiasts, and anyone who wants a free, simple NAS without the overhead of ZFS or the cost of Unraid.

Pros: - Extremely lightweight — runs on a Raspberry Pi 5 with a USB 3.0 enclosure - Free and open source — no license costs, no device limits - Flexible storage — choose mdadm, ZFS, SnapRAID+mergerfs, or plain drives - Debian underneath — use apt, systemd, and standard Linux tooling - Active community — OMV-extras repository maintained by an enthusiastic contributor base

Cons: - No built-in bit rot protection without ZFS — mdadm alone does not checksum data - Weaker Docker UI — relies on Portainer plugin; no integrated container management like Unraid - Development pace is moderate — major updates follow Debian release cycles (12–24 months) - Plugin ecosystem is smaller than Unraid’s Community Applications

Synology DSM 7.2 (Pre-Built Hardware)

Synology is the “it just works” option. You buy a Synology NAS appliance — a compact box with drive bays, an Intel or ARM CPU, and pre-installed DiskStation Manager (DSM) — plug in drives, and go. There is no build process, no OS installation, no hardware compatibility research. DSM is the most polished NAS operating system on the market, with a desktop-like web interface, mobile apps, and a mature ecosystem of first-party packages.

Key features:

Synology Hybrid RAID (SHR) — Synology’s proprietary RAID that allows mixing different drive sizes, similar to Unraid’s philosophy but with real-time striping for better performance
Btrfs with data checksums — Synology uses Btrfs on top of Linux RAID, providing bit rot protection when checksum is enabled on shared folders
Synology Packages — first-party apps for photo management (Synology Photos), surveillance (Surveillance Station), office (Synology Office), backup (Active Backup for Business, Hyper Backup), and media (Video Station, Audio Station)
Container Manager — Synology’s Docker UI, recently upgraded to support Docker Compose natively
QuickConnect — remote access without port forwarding or a VPN (proxied through Synology’s servers)
Mobile apps — DS File, DS Photo, DS Cam, DS Finder, and more on iOS and Android

Hardware considerations: Entry-level 2-bay models (DS223j) start around $200, while 4-bay Plus-series models (DS923+) run $600+, and 8-bay units exceed $1,000. The hardware is underpowered compared to a DIY build at the same price — a DS923+ has a Ryzen R1600 with 4 GB RAM, while $600 buys a used mini PC with an i5 and 32 GB RAM. You pay for the software and the turnkey experience, not raw performance.

Best for: Users who want zero setup effort, premium mobile apps for family use, and are willing to pay more for less hassle.

Pros: - Most polished NAS OS — intuitive web UI, beautiful mobile apps, seamless ecosystem - Zero build time — unbox, insert drives, power on, and use - SHR allows mixed drive sizes with striping performance — best of both worlds - Excellent backup software — Hyper Backup, Active Backup, and Snapshot Replication are best-in-class - QuickConnect for easy remote access — no reverse proxy or VPN setup needed - Btrfs checksums for data integrity when enabled on shared folders

Cons: - Expensive hardware for the specs — you pay a significant premium for the software - Vendor lock-in — migrating away from Synology to DIY requires planning - Limited upgradeability — CPU, RAM (sometimes soldered), and NIC are fixed - Proprietary OS — you are dependent on Synology for security updates and feature releases - Some models have soldered RAM and non-standard drive caddies

Which NAS OS Should You Choose? — Decision Tree

There is no single “best” NAS — the right choice depends on your drives, your hardware, and what you value most. Here is a decision tree to guide you:

“Do you want to buy hardware, plug it in, and never open a terminal?” → Get a Synology. Nothing else matches the polish and convenience. Pay the premium and move on.
“Do you have a collection of random, mismatched drives?” → Unraid is your best friend. Its parity array handles any mix of sizes and brands. You can add or replace drives individually over time without rebuilding the entire array.
“Do you have matched drives and care deeply about data integrity?” → TrueNAS 26 with ZFS. If you buy drives in matching pairs or sets, ZFS gives you checksums, snapshots, replication, and self-healing that no other option matches. Invest in ECC RAM if you can.
“Are you on a tight budget, using old hardware, or a Raspberry Pi?” → OpenMediaVault. It runs on anything, costs nothing, and supports every storage technology under the sun. Pair it with SnapRAID + mergerfs for a Unraid-like experience, or enable the ZFS plugin if your hardware supports it.
“Do you want to run Plex/Jellyfin with hardware transcoding?” → Unraid or TrueNAS. Unraid’s GPU passthrough is more straightforward, but TrueNAS 26 also supports GPU assignment to apps. Both work — Unraid edges ahead on ease.
“Are you unsure and just want to experiment?” → Start with OpenMediaVault. It is free, runs in a VM, and costs nothing to try. If you outgrow it, the data on your drives can be migrated to TrueNAS or Unraid later.

DIY NAS Hardware Recommendations for 2026

Building your own NAS gives you far more performance per dollar than a Synology — but you need to choose the right hardware. Here are three build tiers matched to the NAS OS options above. For more detailed hardware guidance, see our homelab hardware guide and mini PC home server roundup.

Budget Build (~$200–350) — OpenMediaVault

Base: Raspberry Pi 5 (8 GB) with Argon EON case (4-bay SATA) — around $180 total
Alternative: Used HP EliteDesk 800 G4 Mini (i5-8500T, 16 GB RAM) off eBay — $150
Drives: 2× 4 TB refurbished enterprise HDDs (HGST/WD) ~$50 each
Why OMV: Lightweight enough for a Pi, or pairs well with the EliteDesk’s 35 W TDP
Note: Use a powered USB 3.0 hub or SATA HAT for the Pi — the onboard USB ports may not deliver enough power for spinning drives

Mid-Range Build (~$500–800) — Unraid or TrueNAS

Base: Topton N22 / N305 board (Intel N305, 6× SATA, 2× M.2, 2× 2.5GbE) — $220 on AliExpress
Case: Jonsbo N3 (8-bay hot-swap, ITX) — $150
RAM: 32 GB DDR5 SODIMM — $80
PSU: SFX 450W Gold — $90
Drives: Start with 3× 8 TB WD Red Plus or Seagate IronWolf — $160–200 each
Flexibility: This build runs TrueNAS (with matched 8 TB drives in RAID-Z1) or Unraid (add drives later one at a time). The N305’s Quick Sync supports Plex transcoding.

Performance Build (~$1,000+) — TrueNAS 26

Base: Intel Core i5-13500 (Raptor Lake, 14 cores, UHD 770 Quick Sync) — $230
Motherboard: W680 chipset board with IPMI (ASRock Rack W680D4U) or consumer Z790 with 8× SATA — $300
RAM: 64 GB DDR5 ECC — $200
NIC: Intel X710-DA2 (dual SFP+ 10GbE) — $80 on eBay
Drives: 6× 16 TB Seagate Exos X18 in RAID-Z2 — staggered purchase over time
Why TrueNAS: At this tier, you want ZFS with ECC, 10GbE networking, and enterprise-grade data protection. This box will serve your homelab for 5+ years.

Setting Up Your NAS with Docker

All four NAS OS options support Docker, which means your app stack is portable. Whether you run Docker Compose on TrueNAS, Unraid’s Community Applications, OMV with Portainer, or Synology’s Container Manager, the core workflow is the same:

Create a dataset or shared folder for persistent container data (configs, databases, media)
Define your stack in docker-compose.yml
Mount the NAS shares as Docker volumes
Expose services through a reverse proxy (Traefik, Nginx Proxy Manager, or Caddy)

A typical homelab app stack on a NAS might include: - Plex or Jellyfin — media server with GPU transcoding on Unraid or TrueNAS - Nextcloud — private cloud storage and collaboration hub - Immich — Google Photos replacement with AI-powered search - Pi-hole or AdGuard Home — network-wide ad blocking - Vaultwarden — self-hosted password manager - Homepage or Homer — dashboard for all your services

Because the NAS handles storage, your containers stay stateless — back up the NAS datasets, and your entire app stack is recoverable.

FAQ

Q: Can I run a NAS on a Raspberry Pi 5? Yes — OpenMediaVault runs well on a Pi 5 with Debian ARM64. Attach USB 3.0 drives or use a SATA HAT. TrueNAS and Unraid require x86-64 and will not run on ARM. A Pi-based NAS is best for light workloads (file sharing, Pi-hole, small Docker stacks), not heavy media transcoding or ZFS pools.

Q: Is Unraid worth the price when TrueNAS is free? Unraid is worth $59–129 if you have mixed drive sizes, want the easiest Docker experience (Community Applications), or need straightforward GPU passthrough. TrueNAS is the better zero-cost choice if you buy drives in matched sets and value ZFS data integrity above all. The cost is one-time, not recurring — many Unraid users buy once and use it for 5+ years.

Q: Can I migrate from Synology to a DIY NAS? Yes. The safest approach is to build your new NAS (TrueNAS, Unraid, or OMV) on separate hardware, transfer data over the network via rsync or NFS, and then repurpose or sell the Synology. Directly importing Synology drives into a DIY build is possible but risky — Synology uses a modified mdadm/LVM layout that may not import cleanly. Plan your migration, keep the Synology powered on until you have verified the data on the new box, and always have a backup.

Q: Do I need ECC RAM for TrueNAS? ECC RAM is strongly recommended but not strictly required for homelab use. The risk is that a memory error could corrupt data in-flight before ZFS writes it to disk — meaning ZFS would checksum the already-corrupted data and never know it was wrong. For media libraries and replaceable data, this risk is acceptable. For irreplaceable family photos, legal documents, or business data, use ECC. 8 GB is the absolute minimum; 16 GB+ lets ZFS cache more data in ARC for faster reads.

Q: Which NAS is best for Plex and media servers? Unraid is the most popular Plex host thanks to its Community Applications one-click install and excellent GPU passthrough support for hardware transcoding. TrueNAS 26 also works well if you are comfortable with the Kubernetes-based Apps system. Synology supports Plex but the underpowered CPUs in many models struggle with transcoding 4K content. The key feature for any Plex host is Intel Quick Sync Video (iGPU) or a dedicated NVIDIA GPU for hardware-accelerated transcoding — check your CPU supports it before building.

Q: How many drives do I need to start? - TrueNAS: Minimum 2 for a mirror, 3 for RAID-Z1. Buy all your drives up front — expanding later requires adding entire new vdevs. - Unraid: Minimum 2 (1 data + 1 parity). You can add drives one at a time indefinitely up to your license limit. - OpenMediaVault: As few as 1 drive (no redundancy). Add a second for RAID 1 mirroring or use SnapRAID with 1 parity + any number of data drives. - Synology: 2-bay minimum for SHR (1-drive redundancy). 4-bay and 8-bay models scale up.

Conclusion

There is no universal “best” NAS operating system — each option excels in a different scenario:

TrueNAS 26 dominates on data integrity. If you buy matched drives, invest in ECC RAM, and want ZFS’s self-healing guarantees, there is no substitute.
Unraid 7.3 wins on flexibility and ease. Its mixed-drive array and Community Applications make it the go-to choice for homelab builders who collect drives over time.
OpenMediaVault 7 is the budget champion. It runs on anything — from a Raspberry Pi to a repurposed office PC — and costs nothing.
Synology DSM is the turnkey solution. Pay the premium, unbox it, and move on with your life.

If you are unsure where to start, install OpenMediaVault on whatever machine you have (or a VM) and get comfortable with the concepts. Once you understand your storage needs — how many drives, what redundancy level, what apps you will host — you can confidently choose TrueNAS or Unraid. The NAS you build today will be the foundation your homelab grows on for years.

Host Ollama on Proxmox 2026: Self-Hosted AI in Your Homelab

2026-06-06T00:33:00+07:00

Reading time: ~20 minutes Audience: Homelab owners who want a private, offline AI assistant without monthly subscriptions Last tested: Proxmox VE 8.2, Ollama 0.5, OpenWebUI 0.4, June 2026

Why Self-Host an LLM?

Cloud AI services come with three problems for homelab users: privacy (your data leaves your network), cost (ChatGPT Plus is $20/month, Claude Pro is $20/month, and API bills add up fast), and availability (outages, rate limits, and terms-of-service changes).

Running Ollama on your Proxmox server solves all three. You get a private, always-on LLM that works even when your internet is down — and the only recurring cost is electricity.

What You’ll Build

By the end of this guide, you will have:

Ollama serving multiple open-weight models (Llama 3.3, Mistral, Phi-4, Qwen 2.5)
OpenWebUI providing a ChatGPT-style chat interface accessible from any device on your LAN
Optional GPU acceleration for 3–10× faster token generation
A Docker Compose stack you can version-control and redeploy in minutes

Hardware Requirements

Minimum (CPU-Only Inference)

Component	Requirement	Real-World Example
CPU	4 cores, x86_64	Intel N100, old i5-6500
RAM	16 GB (8 GB for OS + 8 GB for a 7B model)	Any DDR4 system
Storage	30 GB free (models are 4–15 GB each)	256 GB SSD minimum
GPU	None required	CPU inference works

Recommended (GPU-Accelerated)

Component	Requirement	Real-World Example
CPU	6+ cores	Intel i5-12400, Ryzen 5 5600
RAM	32 GB	DDR4 3200 MHz
GPU	NVIDIA RTX 3060 12 GB, RTX 4060 Ti 16 GB, or Intel ARC A770 16 GB	Buy used on eBay
Storage	100 GB NVMe	WD Black SN770

VRAM rule of thumb: A 7B parameter model at Q4_K_M quantization needs ~4.5 GB VRAM. A 13B model needs ~8 GB. A 34B model needs ~20 GB. Match your GPU VRAM to the model size you want to run.

Architecture Decision: LXC vs VM

Proxmox gives you two containerization options. Here is the honest trade-off:

Factor	LXC Container	Full VM
GPU passthrough	Easier — bind-mount `/dev/dri` for Intel iGPU or `/dev/nvidia*` for NVIDIA	Requires PCIe passthrough (locks GPU to one VM)
Performance	Near-native CPU speed	~2–5% virtualization overhead
Docker compatibility	Works if LXC is privileged + nesting=1	Works natively
Isolation	Shares host kernel	Fully isolated
Snapshot/backup	Proxmox backup works	Proxmox backup works
Best for	Intel iGPU (Quick Sync), CPU-only inference	Dedicated NVIDIA GPU, multi-tenant setups

Our recommendation: Start with an LXC container if you only need CPU inference or Intel iGPU acceleration. Use a VM if you have a dedicated NVIDIA GPU you want to pass through.

This guide covers both paths.

Path A: LXC Container Setup (CPU or Intel iGPU)

Step A1: Create the LXC Container

In the Proxmox web UI, click Create CT.
Template: Choose a Debian 12 or Ubuntu 24.04 template.
Root Disk: Allocate 40 GB (you will need space for Docker images and LLM models).
CPU: Assign 4–8 cores.
Memory: Assign 16–32 GB (at least 12 GB for a 7B model).
Network: DHCP or static IP on your LAN bridge.

Step A2: Enable Docker in LXC

After creation, select the container → Options → enable:

Option	Value	Why
`unprivileged container`	No (uncheck)	Docker requires privileges to manage cgroups and networks
`Features: nesting`	Yes (check)	Allows Docker-in-LXC
`Features: keyctl`	Yes (check)	Required by some container runtimes

Security note: An unprivileged LXC is safer, but Docker inside unprivileged LXC containers is unreliable. For a single-user homelab this trade-off is acceptable. If you need stronger isolation, use Path B (VM).

Step A3: Install Docker Engine

SSH into the container or use the Proxmox console:

# Update and install prerequisites
apt update && apt upgrade -y
apt install -y ca-certificates curl

# Add Docker's official GPG key and repository
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
chmod a+r /etc/apt/keyrings/docker.asc

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian $(. /etc/os-release && echo "$VERSION_CODENAME") stable" > /etc/apt/sources.list.d/docker.list

apt update
apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

Verify:

docker run --rm hello-world

Step A4: (Optional) Pass Through Intel iGPU

If your Proxmox host has an Intel iGPU (UHD 630, UHD 730, Iris Xe), you can give the LXC access to it without full PCIe passthrough:

On the Proxmox host, find the render device:

ls -la /dev/dri/
# You should see: renderD128

Edit the LXC config file on the host (/etc/pve/lxc/<CTID>.conf) and add:

lxc.cgroup2.devices.allow: c 226:* rwm
lxc.mount.entry: /dev/dri/renderD128 dev/dri/renderD128 none bind,optional,create=file
lxc.mount.entry: /dev/dri/card0 dev/dri/card0 none bind,optional,create=file

Inside the LXC, install the Intel compute runtime:

apt install -y intel-opencl-icd

Verify GPU visibility:

ls -la /dev/dri/
# Should show renderD128 and card0

Path B: Full VM Setup (Dedicated NVIDIA GPU)

Step B1: Create the VM

In Proxmox, click Create VM.
OS: Debian 12 or Ubuntu 24.04 ISO.
System: Change BIOS to OVMF (UEFI) — required for GPU passthrough.
Machine: Set to q35 for better PCIe compatibility.
Disk: 60 GB, VirtIO SCSI.
CPU: 6–12 cores, type host.
Memory: 32 GB minimum.

Step B2: PCIe GPU Passthrough

This is the most technical step. You need to prevent the Proxmox host from claiming the GPU.

On the Proxmox host, identify your GPU:

lspci -nn | grep -i nvidia
# Example output: 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GA106 [GeForce RTX 3060] [10de:2504]

Note the PCI ID (01:00.0) and the vendor:device IDs (10de:2504).

Edit /etc/default/grub and add to GRUB_CMDLINE_LINUX_DEFAULT:

intel_iommu=on iommu=pt vfio-pci.ids=10de:2504

(Replace 10de:2504 with your GPU’s actual IDs. For Intel CPUs use intel_iommu=on; for AMD use amd_iommu=on.)

Update GRUB and reboot:

update-grub
reboot

After reboot, add the GPU to the VM: VM → Hardware → Add → PCI Device → select your GPU. Check All Functions, ROM-Bar, and PCI-Express.

Step B3: Install NVIDIA Drivers Inside the VM

# Inside the VM (Debian 12 example)
apt update && apt install -y build-essential dkms
wget https://us.download.nvidia.com/XFree86/Linux-x86_64/550.120/NVIDIA-Linux-x86_64-550.120.run
chmod +x NVIDIA-Linux-x86_64-550.120.run
./NVIDIA-Linux-x86_64-550.120.run --no-opengl-files

Verify:

nvidia-smi
# Should show GPU name, driver version, and CUDA version

Then install Docker as in Step A3 and the NVIDIA Container Toolkit:

distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg
curl -s -L https://nvidia.github.io/libnvidia-container/$distribution/libnvidia-container.list | \
    sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
    tee /etc/apt/sources.list.d/nvidia-container-toolkit.list

apt update && apt install -y nvidia-container-toolkit
nvidia-ctk runtime configure --runtime=docker
systemctl restart docker

Deploying Ollama + OpenWebUI with Docker Compose

Both paths converge here. Create your stack directory:

mkdir -p ~/ollama-stack && cd ~/ollama-stack

Create docker-compose.yml:

version: "3.8"

services:
  ollama:
    image: ollama/ollama:0.5
    container_name: ollama
    restart: unless-stopped
    volumes:
      - ollama_data:/root/.ollama
    ports:
      - "11434:11434"
    environment:
      - OLLAMA_KEEP_ALIVE=24h        # Keep model in memory between requests
      - OLLAMA_HOST=0.0.0.0           # Listen on all interfaces
      - OLLAMA_NUM_PARALLEL=2         # Max concurrent requests
    # For NVIDIA GPU (comment out if not using GPU):
    # deploy:
    #   resources:

    #           capabilities: [gpu]
    # For Intel iGPU (comment out if not using device):
    # devices:
    #   - /dev/dri:/dev/dri

  openwebui:
    image: ghcr.io/open-webui/open-webui:main
    container_name: openwebui
    restart: unless-stopped
    volumes:
      - openwebui_data:/app/backend/data
    ports:
      - "3000:8080"
    environment:
      - OLLAMA_BASE_URL=http://ollama:11434
      - WEBUI_SECRET_KEY=         # Generate: openssl rand -hex 32
    depends_on:
      - ollama

volumes:
  ollama_data:
  openwebui_data:

Generate a secret key and start:

echo "WEBUI_SECRET_KEY=$(openssl rand -hex 32)" >> .env
docker compose up -d

Pulling Models and First Chat

Pull Your First Model

The easiest way: use OpenWebUI’s built-in model manager at http://your-server-ip:3000 → Settings → Models → Pull a model.

Or via CLI:

# Pull a compact model good for CPU inference (4 GB)
docker exec -it ollama ollama pull llama3.2:3b

# Pull a strong general-purpose model (4.7 GB, needs GPU for speed)
docker exec -it ollama ollama pull llama3.3:latest

# Pull a coding specialist (9 GB)
docker exec -it ollama ollama pull qwen2.5-coder:14b

# List installed models
docker exec -it ollama ollama list

Model Picks for Your Hardware

Hardware	Recommended Models	Speed (tokens/sec)
Intel N100 (CPU only)	llama3.2:3b, phi3:mini, gemma2:2b	5–10 t/s
i5-12400 (CPU only)	llama3.1:8b, mistral:7b, qwen2.5:7b	8–15 t/s
RTX 3060 12 GB	llama3.1:8b, mistral-nemo:12b, qwen2.5:14b	40–80 t/s
RTX 4060 Ti 16 GB	llama3.3:latest, qwen2.5:14b, codestral:22b	50–90 t/s
Dual RTX 3060 (24 GB)	mixtral:8x7b, command-r:35b	25–45 t/s

First Chat via OpenWebUI

Open http://your-server-ip:3000
Create an admin account (first user becomes admin)
Select your model from the dropdown (top-left)
Type: “Explain VLANs like I’m setting up my first homelab network”
Watch the tokens stream back

OpenWebUI also supports: - RAG (Retrieval-Augmented Generation): Upload PDFs, markdown files, or code repos and chat with them - Multiple models simultaneously: Compare answers side-by-side - Web search integration: Configure a search API (SearXNG, Google) for live data - Voice input/output: Using browser Web Speech API

Performance Optimization

1. Keep Models in Memory

The environment variable OLLAMA_KEEP_ALIVE=24h keeps the last-used model loaded in RAM/VRAM for 24 hours. Without it, Ollama unloads models after 5 minutes of inactivity, causing a 3–10 second cold-start delay on the next request.

2. Adjust Context Window

Default context is 2048 tokens. Increase for longer conversations:

docker exec -it ollama ollama run llama3.3:latest
# Inside the REPL:
/set parameter num_ctx 8192
/save my-llama3.3-8k

Or via the API:

curl http://localhost:11434/api/generate -d '{
  "model": "llama3.3:latest",
  "prompt": "Hello",
  "options": { "num_ctx": 8192 }
}'

3. Quantization Level

When pulling models, you can specify quantization:

# Smaller, faster, slight quality loss
docker exec -it ollama ollama pull llama3.2:3b-q4_K_M

# Larger, slower, best quality
docker exec -it ollama ollama pull llama3.2:3b-q8_0

Q4_K_M is the sweet spot for most homelab use: 4-bit quantization with medium quality preservation, fitting 7B models in ~4 GB VRAM.

4. Concurrent Requests

Ollama can handle parallel requests. Set OLLAMA_NUM_PARALLEL=2 (or more with a powerful GPU) in the Compose file. This lets two family members chat simultaneously.

5. Disk I/O

Place Ollama data on an NVMe drive if possible. Model loading reads 4–15 GB from disk. On a SATA SSD, a 7B model loads in ~5 seconds; on NVMe, ~1 second.

Security Considerations

Do Not Expose to the Public Internet

Ollama and OpenWebUI have no built-in authentication by default. They are designed for LAN-only access. If you need remote access:

Use Tailscale or WireGuard VPN to connect to your home network
Put OpenWebUI behind a reverse proxy (NGINX Proxy Manager, Traefik, or Caddy) with HTTPS and HTTP Basic Auth
Never port-forward port 3000 or 11434 directly

OpenWebUI Admin Account

The first user to register in OpenWebUI becomes the administrator. If you expose it to even your LAN, set a strong password immediately.

Model Provenance

Only pull models from Ollama’s official library or Hugging Face mirrors (via ollama pull). Untrusted GGUF files can contain malicious code. Ollama’s library (ollama.com/library) is curated and safe.

Resource Limits

In Docker Compose, you can cap CPU and memory:

services:
  ollama:
    # ... other config ...
    deploy:
      resources:
        limits:
          cpus: '4'
          memory: 16G

This prevents a runaway LLM inference from starving other containers.

Troubleshooting

“Error: unable to load model — CUDA error: out of memory”

The model is too large for your GPU VRAM. Solutions: - Pull a smaller quantization: add -q4_K_M suffix - Use a smaller model: drop from 13B to 7B - Enable CPU offloading: set OLLAMA_NUM_GPU=12 (layers to offload to GPU, remainder on CPU)

OpenWebUI shows “Ollama connection refused”

Verify the Ollama container is running: docker compose ps
Check that OLLAMA_HOST=0.0.0.0 is set (default binds to 127.0.0.1 only)
From inside the OpenWebUI container, test: curl http://ollama:11434/api/tags

Extremely slow on CPU (1–3 tokens/sec)

CPU-only 7B models are inherently slow on consumer hardware
Switch to a 3B model (e.g., llama3.2:3b) for usable 5–10 t/s on CPU
Consider a used GPU: a GTX 1070 8 GB costs ~$80 on eBay and handles 7B models at 20+ t/s

LXC container won’t start after enabling features

Ensure nesting=1 and keyctl=1 are both enabled. If the issue persists, convert to a VM — Docker-in-LXC is convenient but fragile.

Monitoring and Maintenance

Check Ollama Logs

docker compose logs -f ollama

Update Models

Ollama models don’t auto-update. Periodically check:

docker exec -it ollama ollama list
docker exec -it ollama ollama pull llama3.3:latest  # Upgrades if newer version exists

Update the Stack

cd ~/ollama-stack
docker compose pull       # Pull latest images
docker compose up -d      # Recreate with new images
docker image prune -f     # Clean old images

Disk Usage

docker exec -it ollama du -sh /root/.ollama/models/
# Delete unused models:
docker exec -it ollama ollama rm phi3:mini

Beyond the Basics

Add SearXNG for Web Search

OpenWebUI supports web search via SearXNG. Add to your Compose file:

  searxng:
    image: searxng/searxng:latest
    container_name: searxng
    restart: unless-stopped
    ports:
      - "8080:8080"
    volumes:
      - searxng_data:/etc/searxng
    environment:
      - SEARXNG_BASE_URL=http://searxng:8080

Then in OpenWebUI → Settings → Web Search → set SearXNG URL to http://searxng:8080.

Add Stable Diffusion for Image Generation

  automatic1111:
    image: ghcr.io/ai-dock/stable-diffusion-webui:latest
    container_name: sd-webui
    restart: unless-stopped
    ports:

Cloudflare Tunnel Homelab Guide: Expose Self-Hosted Services Without Port Forwarding (2026)

2026-06-06T00:00:00+07:00

Cloudflare Tunnel Homelab Guide: Expose Self-Hosted Services Without Port Forwarding (2026)

If you run a homelab, you have almost certainly wrestled with the same question: how do I safely access my services from outside my home network? The traditional answer involves port forwarding on your router, dynamic DNS updates, and hoping your ISP hasn’t put you behind CGNAT. It is fragile, it exposes your home IP address to the world, and it is one misconfigured firewall rule away from disaster.

Cloudflare Tunnel (powered by cloudflared) eliminates all of those problems. It creates an encrypted outbound-only connection from your homelab to Cloudflare’s edge network. No open ports. No dynamic DNS. No exposed IP addresses. And you get Cloudflare’s DDoS protection, free SSL certificates, and global CDN for free.

In this guide, Dev walks through everything: what Cloudflare Tunnel actually is, how to deploy it with Docker, how to integrate it with Nginx Proxy Manager, and how to layer on Zero Trust access policies so only you (or your family) can reach sensitive dashboards.

What Is Cloudflare Tunnel and Why Should You Use It?

Cloudflare Tunnel is a secure, outbound-only tunnel that connects your local services to Cloudflare’s global network. The daemon — cloudflared — runs inside your homelab and establishes a persistent connection to Cloudflare’s edge. When a visitor hits jellyfin.yourdomain.com, Cloudflare proxies that request through the tunnel directly to your local service.

What this replaces:

Old Way	Cloudflare Tunnel Way
Open port 443 on router	Zero open ports
Dynamic DNS (DuckDNS, afraid.org)	Not needed — Cloudflare handles DNS
Let’s Encrypt cert renewal cron jobs	Free Cloudflare edge certificates, auto-renewed
ISP CGNAT blocks everything	Works behind any NAT, even double-NAT
Your home IP exposed to attackers	Only Cloudflare’s IPs are visible

What you need before starting:

A domain name — any registrar works, but you must point its nameservers to Cloudflare (free plan included).
A Cloudflare account — free tier is more than enough for homelab use.
A machine running Docker — a Proxmox LXC, a Raspberry Pi, an old laptop, anything with Docker works.
Services you want to expose — Jellyfin, Nextcloud, Home Assistant, Portainer, whatever you self-host.

Important caveat: Cloudflare Tunnel decrypts traffic at their edge and re-encrypts it over the tunnel. For the vast majority of homelab services, this is perfectly fine. If you are handling legally protected data (HIPAA, PCI-DSS, etc.), you probably should not be self-hosting it on a homelab connection anyway. For everything else — media servers, dashboards, family photo galleries — Cloudflare Tunnel is an excellent fit.

Step 1: Set Up Your Domain on Cloudflare

If you already have your domain on Cloudflare, skip to Step 2.

Log into the Cloudflare dashboard and click Add a Site. Enter your domain name and follow the onboarding wizard. Cloudflare will scan your existing DNS records and import them automatically.

Once your domain is added, go to your domain registrar (Namecheap, Porkbun, Google Domains, etc.) and replace the existing nameservers with the two Cloudflare-provided nameservers. Propagation typically takes a few minutes but can take up to 24 hours in rare cases.

In the Cloudflare dashboard, go to SSL/TLS → Overview and set your encryption mode to “Full.” This ensures traffic between Cloudflare’s edge and your tunnel is encrypted. Without this, you may see redirect loops or SSL errors when accessing your services.

Step 2: Create a Cloudflare Tunnel

Navigate to Zero Trust → Networks → Tunnels in the Cloudflare dashboard. (If this is your first time in the Zero Trust dashboard, you will be asked to pick a team name — choose anything, it is just an internal identifier and can be changed later.)

Click Create a tunnel, give it a name (e.g., homelab-tunnel), and click Save tunnel.

Cloudflare will now show you installation instructions for various platforms. Choose Docker and copy the token from the command. It looks like:

docker run cloudflare/cloudflared:latest tunnel --no-autoupdate run \
  --token eyJhIjoiYWJjZGVmZ2hpamtsbW5vcHFyc3R1dnd4eXoxMjM0NTY3ODkwIn0=

The --token value is your tunnel’s authentication credential — treat it like a password. Do not commit it to a public Git repository. We will store it properly in a Docker Compose file in the next step.

Before you close this screen, scroll down to the Public Hostnames section. This is where you map your domain names to local services. Add your first entry:

Field	Value
Subdomain	`jellyfin` (or whatever you like)
Domain	`yourdomain.com`
Type	`HTTP`
URL	`192.168.1.100:8096` (your Jellyfin IP and port)

Click Save hostname. Repeat for any other services you want to expose. You can always come back and add more later.

Step 3: Deploy cloudflared with Docker Compose

While you could add public hostnames one-by-one through the Cloudflare dashboard, a cleaner approach for homelab use is to configure cloudflared with a YAML config file. This keeps all your tunnel routing rules in one place — version-controlled, documented, and easy to recreate if your server dies.

Create a directory for your tunnel configuration:

mkdir -p ~/cloudflare-tunnel

Create a config.yml inside that directory:

# ~/cloudflare-tunnel/config.yml
tunnel: YOUR-TUNNEL-ID
credentials-file: /home/nonroot/.cloudflared/YOUR-TUNNEL-ID.json

ingress:
  # Route by hostname to Nginx Proxy Manager
  - hostname: jellyfin.yourdomain.com
    service: http://nginx-proxy-manager:80
  - hostname: nextcloud.yourdomain.com
    service: http://nginx-proxy-manager:80
  - hostname: homeassistant.yourdomain.com
    service: http://nginx-proxy-manager:80
  - hostname: portainer.yourdomain.com
    service: http://nginx-proxy-manager:80

  # Catch-all: return 404 for unmatched hostnames
  - service: http_status:404

Why point everything at Nginx Proxy Manager? Instead of configuring each service’s internal IP and port in Cloudflare’s dashboard, you route all traffic through Nginx Proxy Manager (NPM). NPM handles SSL termination on the local side and lets you manage subdomains, proxy hosts, and access lists from one clean web UI. If you followed our Nginx Proxy Manager Docker Compose guide, you already have this set up.

Note: Replace YOUR-TUNNEL-ID with the actual tunnel ID from the Cloudflare dashboard (visible under Zero Trust → Networks → Tunnels, in the format of a UUID like abcdef12-3456-7890-abcd-ef1234567890).

Now create your docker-compose.yml:

# ~/cloudflare-tunnel/docker-compose.yml
version: "3.8"

services:
  cloudflared:
    image: cloudflare/cloudflared:latest
    container_name: cloudflared
    restart: unless-stopped
    command: tunnel run
    environment:
      - TUNNEL_TOKEN=${TUNNEL_TOKEN}
    # Alternative: use config.yml with credentials file
    # volumes:
    #   - ./config.yml:/home/nonroot/.cloudflared/config.yml:ro
    #   - ./credentials.json:/home/nonroot/.cloudflared/${TUNNEL_ID}.json:ro
    # command: tunnel --config /home/nonroot/.cloudflared/config.yml run
    networks:
      - proxy_network

networks:
  proxy_network:
    external: true
    name: nginx-proxy-manager_default  # Replace with your NPM network name

Create a .env file in the same directory:

# ~/cloudflare-tunnel/.env
TUNNEL_TOKEN=eyJhIjoiYWJjZGVmZ2hpamtsbW5vcHFyc3R1dnd4eXoxMjM0NTY3ODkwIn0=

Security tip: Never commit .env to version control. Add it to .gitignore immediately.

Start the tunnel:

cd ~/cloudflare-tunnel
docker compose up -d

Check the logs to confirm the connection:

docker logs cloudflared

You should see a line like:

INF Registered tunnel connection connIndex=0

If you see ERR messages about failed connections, double-check your TUNNEL_TOKEN value and ensure your server can reach region1.v2.argotunnel.com on port 7844 (outbound).

Step 4: Configure Nginx Proxy Manager for Tunnel Traffic

With the tunnel running, traffic arriving at jellyfin.yourdomain.com is routed through Cloudflare’s edge, through the encrypted tunnel, and lands at Nginx Proxy Manager on port 80 inside your Docker network. Now you need NPM to know what to do with that request.

Log into your Nginx Proxy Manager web UI (typically http://192.168.1.100:81) and add a new proxy host:

Field	Value
Domain Names	`jellyfin.yourdomain.com`
Scheme	`http`
Forward Hostname / IP	`192.168.1.100` (or the Docker service name)
Forward Port	`8096`
Block Common Exploits	✅ Enabled
Websockets Support	✅ Enabled (needed for Jellyfin, Home Assistant, etc.)

Under the SSL tab:

Field	Value
SSL Certificate	“None” — Cloudflare handles SSL at the edge
Force SSL	❌ Disabled — otherwise you may create redirect loops
HTTP/2 Support	✅ Enabled
HSTS Enabled	✅ Enabled
HSTS Subdomains	✅ Enabled

Click Save. Repeat for each service you want to expose.

Why SSL=None locally? Cloudflare terminates SSL at their edge and forwards traffic to your tunnel over an encrypted QUIC connection. The hop from cloudflared to NPM inside your Docker network is local traffic and doesn’t need additional encryption. Adding SSL on that hop adds latency with no security benefit.

Step 5: Add Cloudflare Zero Trust Access (Optional but Recommended)

Exposing a service to the internet means anyone who discovers the URL can attempt to access it. For dashboards like Portainer, Proxmox, or Grafana — tools you definitely do not want random internet users interacting with — add an authentication layer with Cloudflare Zero Trust.

In the Cloudflare Zero Trust dashboard, go to Access → Applications and click Add an application. Choose Self-hosted.

Configure:

Field	Value
Application name	`Portainer`
Subdomain	`portainer`
Domain	`yourdomain.com`
Identity providers	Select at least one (Google, GitHub, or One-Time PIN via email are all free)

Under Policies, add a rule:

Field	Value
Policy name	`Allow family`
Include	Emails ending in `@yourdomain.com` (or list specific email addresses)

Save the policy and the application. Now when anyone visits portainer.yourdomain.com, they will first see a Cloudflare login page. Only authenticated users matching your policy can proceed to the actual Portainer UI. No VPN needed, no app installed — just a browser login.

For services you want fully public (like a blog), simply skip the Zero Trust Access step. Cloudflare Tunnel will serve them normally without any authentication gate.

Advanced: Using config.yml with Multiple Networks

If you run services across multiple Docker networks or on different physical hosts, the ingress rules in config.yml give you full flexibility:

ingress:
  # Service on Docker network "media"
  - hostname: jellyfin.yourdomain.com
    service: http://jellyfin:8096
    originRequest:
      connectTimeout: 30s
      noTLSVerify: true

  # Service on a different physical host (Proxmox LXC at 192.168.1.50)
  - hostname: proxmox.yourdomain.com
    service: https://192.168.1.50:8006
    originRequest:
      noTLSVerify: true  # Proxmox uses self-signed certs

  # SSH access via browser (Cloudflare's browser-based SSH terminal)
  - hostname: ssh.yourdomain.com
    service: ssh://192.168.1.1:22

  # Return 404 for any hostname not explicitly mapped
  - service: http_status:404

To use this approach, switch your Docker Compose command to tunnel --config /home/nonroot/.cloudflared/config.yml run and mount both the config file and the credentials JSON file (downloaded from Cloudflare dashboard under the tunnel’s configuration tab).

Troubleshooting Common Issues

“Error 1033: Argo Tunnel error”

This means Cloudflare could not reach your tunnel. Check docker logs cloudflared. Common causes:

The TUNNEL_TOKEN is incorrect or expired.
Your server cannot reach Cloudflare’s tunnel endpoints (firewall blocking outbound UDP/TCP on port 7844).
The tunnel is stopped or crashed.

“Too Many Redirects” in the browser

This is almost always caused by SSL misconfiguration. Fixes:

In Cloudflare SSL/TLS settings, ensure the mode is set to Full, not Flexible.
In Nginx Proxy Manager, ensure Force SSL and SSL Certificate are both set to None on the proxy host for tunnel traffic.
Clear your browser cache or test in an incognito window.

“502 Bad Gateway” from Cloudflare

Your tunnel is connected, but it cannot reach the backend service. Check:

Is the service actually running? docker ps | grep jellyfin
Are cloudflared and your service on the same Docker network? If using the simple token method, cloudflared needs to reach the service by its Docker host IP and port. If using config.yml, ensure the service name in the service field resolves from the cloudflared container.
Is your NPM proxy host pointing to the correct internal IP and port?

Slow performance on media streaming

Cloudflare Tunnel is not designed for high-bandwidth video streaming through their free tier. While it works, Cloudflare’s Terms of Service (Section 2.8) prohibit serving disproportionate amounts of video or other non-HTML content through their CDN on the free plan. For streaming Jellyfin or Plex to remote users, consider:

Tailscale (free for up to 100 devices) — direct peer-to-peer encrypted connection.
WireGuard VPN — self-hosted on a cheap VPS as a relay.
Direct port forwarding for streaming only (with proper firewall rules and fail2ban).

Use Cloudflare Tunnel for the web UI, metadata, and authentication; route the actual video stream through a separate path if you have more than a handful of remote users.

Security Checklist

Before you walk away from this setup, run through these security essentials:

[ ] Cloudflare SSL/TLS mode set to Full (not Flexible — Flexible sends unencrypted traffic between Cloudflare and your tunnel, which defeats the purpose).
[ ] Tunnel token stored in .env, not committed to Git.
[ ] NPM “Block Common Exploits” enabled on every proxy host.
[ ] Zero Trust Access policies applied on admin dashboards (Portainer, Proxmox, Grafana, Cockpit, etc.).
[ ] Cloudflare WAF (Web Application Firewall) enabled — free tier includes basic DDoS protection and managed rulesets. Go to Security → WAF in the Cloudflare dashboard.
[ ] Bot Fight Mode enabled (Security → Bots) — blocks basic automated scanners at the edge.
[ ] Regularly review Cloudflare Access audit logs (Zero Trust → Logs → Access) to see who is authenticating and from where.

What We Covered

Cloudflare Tunnel gives you a production-grade way to expose self-hosted services without touching your router’s port forwarding rules. You get free SSL, DDoS protection, and optional authentication gates — all running on infrastructure that serves a significant portion of the internet.

In this guide, you set up:

A Cloudflare Tunnel from your homelab to Cloudflare’s edge.
Docker Compose deployment of cloudflared with environment-based token management.
Nginx Proxy Manager integration so you manage all routing from one UI.
Zero Trust Access policies to gate sensitive services behind email-based authentication.
Troubleshooting steps for the three most common deployment issues.

From here, consider exploring Cloudflare’s WAF custom rules to block specific countries or IP ranges, setting up Cloudflare Pages for a static blog (perhaps using Pelican — our favorite), or adding Cloudflare R2 as an S3-compatible backup target for your homelab data. The free tier is remarkably generous for personal projects.

Your homelab services are now reachable, fast, and — most importantly — secure. All without opening a single port on your router.

Home Assistant Docker Compose for Homelab 2026: From Container to Smart Home Stack

2026-06-06T00:00:00+07:00

Home Assistant Docker Compose for Homelab 2026: From Container to Smart Home Stack

Reading time: ~14 minutes Audience: Homelab owners who want a self-hosted smart home without vendor lock-in

Introduction: Docker Compose for Home Assistant — Why It Makes Sense in 2026

Home Assistant has grown from a hobbyist project into the most popular open-source smart home platform on the planet. The r/homeassistant subreddit sits at over 250,000 members, and every major smart device manufacturer now either supports Home Assistant directly or has a community integration that works better than the official app. But there is one persistent debate that trips up newcomers: should you run Home Assistant OS (HAOS), Home Assistant Container (Docker), or Home Assistant Core (bare Python)?

If you already run a homelab — Proxmox, a mini PC, or even a Raspberry Pi 5 with a handful of Docker containers — the answer leans strongly toward Docker Compose. Here is why: you already have Docker running for your media server, reverse proxy, DNS filter, and monitoring stack. Adding Home Assistant as another Compose service keeps your infrastructure uniform, your management tooling consistent, and your backup strategy identical across every service.

This guide covers the complete stack: Home Assistant Core in Docker, Mosquitto MQTT, Zigbee2MQTT for USB dongle integration, an optional Node-RED automation sidecar, reverse proxy with Nginx Proxy Manager, remote access via Cloudflare Tunnel, and Proxmox LXC USB passthrough. Every code block is copy-paste ready for 2026.

Why Docker Compose for Home Assistant in a Homelab?

Before writing a single YAML line, you need to understand the tradeoffs. Home Assistant offers three official installation methods, and they are not interchangeable.

HAOS vs Docker Compose vs Core: The Decision Tree

Method	What It Is	Best For	Watch Out For
HAOS	Full OS image (rootfs or VM)	Raspberry Pi dedicated, VM-only homelab	Steals an entire device or VM; can’t run other Docker containers alongside
Docker Compose	`homeassistant/home-assistant` container	Homelab with existing Docker stack	No add-on store; replace add-ons with separate containers
Home Assistant Core	`pip install homeassistant`	Python developers, custom integrations	No supervisor; manual OS dependency management

Choose HAOS if: You want a dedicated appliance, do not run other server workloads, and want the one-click add-on store for things like Node-RED, ESPHome, and DuckDNS.

Choose Docker Compose if: You already run Docker for other services (Jellyfin, Nginx Proxy Manager, Pihole, Grafana), you use Portainer or Dockge for container management, and you are comfortable running companion services as separate containers instead of add-ons.

Choose Core if: You are developing custom integrations in Python and need direct filesystem access without container isolation.

The Add-On Question (and the Docker Workaround)

The number-one reason people hesitate to use Docker is the add-on store. In HAOS, add-ons are pre-packaged Docker containers that Home Assistant manages for you — Node-RED, ESPHome, Mosquitto, Zigbee2MQTT, and file editors all install with one click.

In Docker Compose, you simply run each add-on as a separate container in the same Compose stack. The result is identical — Mosquitto still talks to Home Assistant over the internal Docker network; Zigbee2MQTT still publishes to MQTT — but you manage them through docker compose pull && docker compose up -d instead of the Supervisor UI. For homelabbers already managing 20 containers, this is a feature, not a bug: one workflow, one update cadence, no split-brain management.

For the few add-ons that do not have standalone Docker images (like the Google Drive Backup add-on), you use HACS (Home Assistant Community Store) to install equivalent custom integrations directly inside the Home Assistant container — no Supervisor required.

What You’ll Need

Hardware

Tier	Hardware	RAM	Storage	Power	Best For
Budget	Raspberry Pi 5 (8 GB) + 128 GB SSD	8 GB	128 GB SSD	8–12W	Starter smart home (lights, sensors, 1–2 cameras)
Standard	Intel N100 Mini PC (Beelink S12 Pro, Minisforum UN100)	16 GB	256 GB NVMe	12–18W	Full smart home + Frigate NVR + 4–8 cameras
Enthusiast	Proxmox VM (4 vCPU, 8 GB RAM) on existing homelab server	8 GB	64 GB virtual disk	Shared	Consolidation — run HA alongside other VMs/CTs
Power User	Intel N305 or AMD Ryzen 5825U Mini PC	32 GB	512 GB NVMe	25–40W	Frigate AI object detection, Whisper voice, Matter controller

Zigbee/Z-Wave USB Dongle Recommendations (2026):

Sonoff ZBDongle-P (CC2652P) — ~$15, excellent range, Zigbee2MQTT and ZHA compatible
ConBee III (RaspBee III for Pi GPIO) — ~$40, deCONZ or Zigbee2MQTT, very mature
Home Assistant SkyConnect (EFR32MG21) — ~$30, official Nabu Casa hardware, Thread/Matter ready, ZHA native
Aeotec Z-Stick 7 (Z-Wave 700 series) — ~$50, best Z-Wave dongle, 700-series for long range

Software

Docker Engine 24+ and Docker Compose v2 (bundled with Docker)
Git for version-tracking your Compose files
Static IP or mDNS (Avahi) on the host so integrations can discover it reliably

Project Structure

Create a clean directory on your Docker host. Version-control it with Git — your Compose file is infrastructure as code, and you will thank yourself after the first accidental docker compose down.

~/docker/homeassistant/
├── .env                  # Version tags and secrets
├── docker-compose.yml    # Main stack
├── mosquitto/
│   └── config/
│       └── mosquitto.conf
├── zigbee2mqtt/
│   └── data/
│       └── configuration.yaml
├── node-red/
│   └── data/
└── homeassistant/
    └── config/           # Auto-created on first run

The .env file pins exact versions so you control when updates happen:

# .env — Version pins for Home Assistant smart home stack
# Update these manually and review changelogs before bumping
HA_VERSION=2026.6.0
MOSQUITTO_VERSION=2.0.18
Z2M_VERSION=1.37.0
NODE_RED_VERSION=4.0.2
TZ=Asia/Jakarta

Volume strategy: every container gets a bind-mounted directory under ~/docker/homeassistant/. This keeps backups simple — rsync -a ~/docker/homeassistant/ /mnt/nas/backups/homeassistant/ captures your entire smart home config in one command.

Service-by-Service Explanation

Home Assistant (network_mode: host): Using host networking is the officially recommended approach for the Docker container because Home Assistant relies on mDNS (Bonjour/Avahi), UPnP, and DHCP discovery to find devices on your LAN. Without host mode, many auto-discovered integrations (Google Cast, Apple HomeKit, Philips Hue, Sonos) silently break. The privileged: true flag gives the container access to USB devices — essential for Zigbee/Z-Wave dongles. If your security policy forbids host networking, use a bridge network with explicit port mappings and accept that device discovery will be manual.

Mosquitto (bridge network): This is a standard MQTT broker. It runs on the default bridge network so Home Assistant can reach it at mosquitto:1883 (Docker DNS) if needed, but since Home Assistant is on host mode, you configure the MQTT integration with localhost:1883 instead. The bridge mode keeps Mosquitto isolated while still being reachable from the LAN for non-Docker MQTT clients.

Zigbee2MQTT (bridge with device passthrough): The devices: block maps the physical USB dongle into the container. Find your dongle’s stable path with ls -la /dev/serial/by-id/ — this symlink survives reboots, unlike /dev/ttyUSB0 which can change numbering.

Node-RED (bridge network, optional): If you prefer visual flow-based automation over Home Assistant’s built-in YAML automations, Node-RED is the gold standard. It connects to Home Assistant via the Home Assistant WebSocket API and to MQTT via the broker.

Mosquitto Configuration

Create ./mosquitto/config/mosquitto.conf:

listener 1883
allow_anonymous false
password_file /mosquitto/config/passwd
persistence true
persistence_location /mosquitto/data
log_dest stdout

Set the MQTT credentials (run this after the first docker compose up -d mosquitto):

docker compose exec mosquitto mosquitto_passwd -c /mosquitto/config/passwd homeassistant

Use these credentials when configuring the MQTT integration in Home Assistant.

Zigbee2MQTT Configuration

Create ./zigbee2mqtt/data/configuration.yaml:

homeassistant: true
permit_join: false  # Enable only when pairing new devices
mqtt:
  server: mqtt://localhost:1883
  user: homeassistant
  password: your_password_here
serial:
  port: /dev/ttyUSB0
  adapter: zstack  # For Sonoff ZBDongle-P. Use 'deconz' for ConBee
frontend:
  port: 8080
advanced:
  network_key: GENERATE_A_RANDOM_KEY

Generate the network_key with openssl rand -hex 16 — this encrypts your Zigbee network and must be the same if you ever re-pair devices. Save it somewhere safe.

Step-by-Step Installation

Step 1 — Prepare Your Host

On Proxmox (LXC container): Create an unprivileged LXC container with Debian 12, enable nesting=1 and keyctl=1 in the container options. Install Docker inside the LXC. For USB passthrough, add the LXC device mapping in Proxmox: select the container → Resources → Add → Device Passthrough → /dev/serial/by-id/usb-Silicon_Labs_... — no reboot needed. If you haven’t set up Proxmox yet, see our Proxmox beginner guide.

On Ubuntu/Debian (bare metal or VM):

# Install Docker (official repo method, 2026)
curl -fsSL https://get.docker.com | sudo sh
sudo usermod -aG docker $USER
newgrp docker

# Verify
docker --version
docker compose version

On Raspberry Pi 5:

# Same Docker install, then verify ARM architecture
docker info | grep Architecture  # Should show aarch64

Pi users: Use an SSD via USB 3.0 or NVMe HAT, not a microSD card. Home Assistant writes recorder data continuously; an SD card will fail within 6–12 months under that write load.

Step 2 — Create Directories and Set Permissions

mkdir -p ~/docker/homeassistant/{homeassistant/config,mosquitto/config,zigbee2mqtt/data,node-red/data}
chown -R 1000:1000 ~/docker/homeassistant/node-red/data

Node-RED runs as UID 1000 by default. Home Assistant and Zigbee2MQTT create their own directory structures on first run.

Step 3 — Write the Docker Compose File

Copy the docker-compose.yml and .env from the sections above into ~/docker/homeassistant/. Adjust your Zigbee dongle path under devices: in the Zigbee2MQTT service. If you don’t have a Zigbee dongle yet, comment out the entire zigbee2mqtt service — you can add it later without rebuilding the stack.

Step 4 — Start the Stack

cd ~/docker/homeassistant
docker compose up -d

# Watch logs to confirm startup
docker compose logs -f homeassistant

Wait 2–3 minutes for the first-run initialization. Home Assistant downloads several Python wheels and builds the frontend on first start. You will know it’s ready when the logs show "Home Assistant initialized in X seconds".

Step 5 — First-Run Configuration

Open http://<host-ip>:8123 in a browser. Home Assistant walks you through:

Create owner account — This is your admin user. Use a strong password.
Name your home — Pick the location for timezone, sunrise/sunset, and weather automations.
Device discovery — Home Assistant auto-scans for devices on your network (printers, Chromecasts, Roku, Philips Hue bridges). Accept or skip.
Integrations — You will be prompted to install discovered integrations. At minimum, install MQTT and point it to localhost:1883 with the credentials you set in Mosquitto.

Step 6 — Install HACS (Home Assistant Community Store)

HACS is the Docker user’s replacement for the add-on store. It gives you access to thousands of custom integrations and Lovelace dashboard themes — install once, then browse and one-click install forever.

docker compose exec homeassistant bash
wget -O - https://get.hacs.xyz | bash -
exit
docker compose restart homeassistant

After restart, go to Settings → Devices & Services → Add Integration → HACS. You will need a free GitHub account to authenticate. Once HACS is installed, use it to add integrations like Frigate (NVR), Adaptive Lighting, and Browser Mod.

Step 7 — Add Zigbee2MQTT Integration

After the Zigbee2MQTT container is running (check at http://<host-ip>:8080), enable the frontend, then in Home Assistant go to Settings → Devices & Services → Add Integration → MQTT. Home Assistant auto-discovers the Zigbee2MQTT bridge and all paired devices appear automatically.

To pair your first Zigbee device: set permit_join: true in zigbee2mqtt/data/configuration.yaml, restart the container (docker compose restart zigbee2mqtt), then put your device in pairing mode (usually hold a button for 5 seconds). The device appears in the Home Assistant dashboard within seconds. Disable permit_join immediately afterward.

Step 8 — Backup Strategy

Your entire configuration lives in ~/docker/homeassistant/. Back it up with:

# Stop containers to ensure consistent backups
cd ~/docker/homeassistant && docker compose stop
rsync -a ~/docker/homeassistant/ /mnt/nas/backups/homeassistant/$(date +%Y-%m-%d)/
docker compose up -d

Automate this with a cron job or a Proxmox Backup Server job (if your Docker host is a Proxmox VM/LXC). The Home Assistant container also has a built-in backup service accessible at Settings → System → Backups — use it to create snapshots that include add-on and integration data.

Reverse Proxy & Remote Access

Exposing Home Assistant directly on port 8123 to the internet is a bad idea. Use a reverse proxy — it gives you HTTPS, path-based routing, and access control in one place.

Option 1: Nginx Proxy Manager (Recommended)

If you already use Nginx Proxy Manager (and you should — see our NPM Docker Compose guide), adding Home Assistant is a 30-second task:

In NPM, add a new Proxy Host.
Domain: home.example.com (or whatever subdomain you use).
Forward Hostname/IP: <host-ip> and Port: 8123.
Enable WebSocket Support (critical — Home Assistant uses WebSockets for real-time state updates).
Request an SSL certificate via Let’s Encrypt.

That is it. Your Home Assistant is now accessible at https://home.example.com with automatic HTTPS renewal.

Option 2: Cloudflare Tunnel (No Port Forwarding)

If your ISP uses CGNAT or you want zero open ports, use Cloudflare Tunnel. See our Cloudflare Tunnel homelab guide for the full setup, but the Home Assistant-specific config looks like:

# In your cloudflared config.yml
tunnel: <tunnel-id>
credentials-file: /etc/cloudflared/<tunnel-id>.json

ingress:
  - hostname: home.example.com
    service: http://<host-ip>:8123
  - service: http_status:404

Cloudflare Tunnel wraps your Home Assistant in Cloudflare’s CDN and DDoS protection. Bonus: you get free analytics on who accesses your smart home (and from where).

Option 3: Tailscale Mesh VPN

For maximum security with zero exposed ports, install Tailscale on both your Docker host and your phone/laptop. Access Home Assistant at http://<tailscale-hostname>:8123 from anywhere. No reverse proxy, no DNS records, no TLS certificates needed. Combine this with Tailscale’s subnet routing to access your entire LAN remotely through one node.

Zigbee/Z-Wave USB Dongle Passthrough

This is the section that trips up most Docker users. Passing a USB device into a container is straightforward on bare metal and slightly more involved on Proxmox LXC.

Bare Metal / VM Host

Use the devices: block in docker-compose.yml as shown above. Find your dongle’s stable symlink:

ls -la /dev/serial/by-id/
# Output: usb-Silicon_Labs_CP2102N_USB_to_UART_Bridge_Controller_XXXXXXXX -> ../../ttyUSB0

Use the /dev/serial/by-id/... path in your Compose file — it survives USB port changes and reboots.

Permission fix: If Zigbee2MQTT logs show "Error: cannot open /dev/ttyUSB0":

sudo usermod -aG dialout $USER
# Log out and back in, or reboot

The privileged: true flag on the Home Assistant container usually handles this, but the Zigbee2MQTT container needs the dialout group access on the host.

Proxmox LXC USB Passthrough

In the Proxmox web UI: 1. Select your LXC container → Resources → Add → Device Passthrough. 2. Choose /dev/serial/by-id/usb-Silicon_Labs_... from the dropdown. 3. Restart the LXC.

Inside the LXC, the device appears at the same path. No container-level devices: block is needed — the Proxmox host-level passthrough supersedes it.

Common issue: If the device does not appear inside the LXC, check that the LXC is privileged (not recommended for security) or add the device’s cgroup permissions in /etc/pve/lxc/<container-id>.conf:

lxc.cgroup2.devices.allow: c 188:* rwm
lxc.mount.entry: /dev/serial/by-id/usb-Silicon_Labs_CP2102N_USB_to_UART_Bridge_Controller_XXXXXXXX dev/serial/by-id/usb-Silicon_Labs_CP2102N_USB_to_UART_Bridge_Controller_XXXXXXXX none bind,optional,create=file

Updating & Maintenance

Docker Compose Update Workflow

Home Assistant releases a new version every month. Update your stack with:

cd ~/docker/homeassistant

# Pull new images (respects version pins in .env)
docker compose pull

# Recreate containers with new images
docker compose up -d

# Remove old dangling images
docker image prune -f

Version Pinning Strategy

The .env file pins major.minor.patch versions. Never use the latest tag — Home Assistant introduces breaking changes in minor releases (e.g., a Python version bump, an integration deprecation). Before bumping a version:

Read the Home Assistant release notes.
Check the Breaking Changes section.
Review your active integrations for deprecation warnings.
Bump the version in .env, pull, and restart.

Portainer-Managed Updates

If you use Portainer (and you should — see our Portainer Docker management guide), you can manage the entire Home Assistant stack through the Portainer UI. Add the stack via Stacks → Add Stack → Web Editor, paste your Compose file, and deploy. Portainer shows container logs, resource usage, and update status — useful when you are on mobile and need to restart Home Assistant without SSH.

Troubleshooting Common Issues

Home Assistant Not Discovering Devices (mDNS/DLNA/UPnP)

Symptom: Google Cast, Sonos, Philips Hue, or Apple HomeKit devices do not appear in auto-discovery.

Fix: Verify network_mode: host is set on the homeassistant service. If you must use bridge mode for security reasons, you lose auto-discovery — add devices manually by IP address in the integration settings.

Zigbee2MQTT Cannot Access USB Dongle

Symptom: Logs show "Error: Error: cannot open /dev/ttyUSB0 (Permission denied)".

Fix: On the host: sudo usermod -aG dialout $USER && newgrp docker. Also verify the device path with ls /dev/serial/by-id/ — the symlink may have changed after a kernel update.

Container Not Starting After Reboot

Symptom: After a host reboot, docker compose ps shows containers as exited.

Fix: Ensure restart: unless-stopped is set on every service. If containers still do not auto-start, check that Docker itself starts on boot: sudo systemctl enable docker.

Database Corruption Recovery

Symptom: Home Assistant starts but history/logbook pages are blank.

Fix: The default SQLite database can corrupt after unexpected power loss. Purge it:

docker compose stop homeassistant
rm ~/docker/homeassistant/homeassistant/config/home-assistant_v2.db
docker compose start homeassistant

You lose history data (entity states, logbook entries) but your configuration (automations, scripts, dashboards) is unaffected — those live in separate YAML files. Consider switching to a MariaDB or PostgreSQL recorder for production setups.

FAQ: Docker Compose vs HAOS vs Core

Q: Can I use add-ons with Docker? No. Add-ons are exclusive to HAOS and Supervisor. In Docker, you run each add-on as a separate container in the same Compose stack. This is a lateral move: Mosquitto as a container works identically to the Mosquitto add-on; it just appears in Portainer instead of the Supervisor UI. For add-ons that do not have standalone Docker images, use HACS custom integrations.

Q: Is Docker less stable than HAOS? No. Under the hood, HAOS runs the same homeassistant/home-assistant Docker image. The Supervisor is a separate container that manages add-ons and snapshots — it does not affect core stability. The stability difference is zero. What changes is who manages the companion services: you (Docker) or the Supervisor (HAOS).

Q: Should I run Home Assistant in a VM instead? If you want HAOS features (add-ons, one-click backups, Google Drive backup) without dedicating a physical machine, a Proxmox VM running HAOS is an excellent middle ground. You get the full HAOS experience while your other Docker containers run in separate VMs or LXCs on the same Proxmox host. The downside: you reserve RAM and CPU for the VM instead of sharing via containers.

Q: How do I back up Home Assistant in Docker? Two methods: (1) rsync the entire ~/docker/homeassistant/ directory while containers are stopped — this captures everything including your Compose file, MQTT config, and Zigbee2MQTT data. (2) Use Home Assistant’s built-in backup tool at Settings → System → Backups to create a .tar snapshot, then copy it off-host with SCP or rsync. Either method works; method 1 is more complete because it captures non-HA data too.

Q: Can I run Home Assistant on a Raspberry Pi 5 with Docker? Yes, and it works well — with one caveat. Use an NVMe SSD (via a HAT or USB 3.0 enclosure), not a microSD card. Home Assistant’s recorder writes to the database continuously; SD cards wear out in 6–12 months under that load. With an SSD, a Raspberry Pi 5 (8 GB) handles a modest smart home of 20–30 Zigbee devices and a few Wi-Fi integrations without breaking a sweat.

Conclusion: Your Smart Home, Your Rules

Running Home Assistant with Docker Compose gives you the best of both worlds: the power and flexibility of the world’s best open-source smart home platform, plus the infrastructure consistency of your existing homelab stack. You manage Home Assistant the same way you manage Jellyfin, Pihole, and Nginx Proxy Manager — one Compose file, one update workflow, one backup strategy.

The tradeoff — no add-on store — is smaller than it appears. HACS fills the integration gap, and running companion services as separate containers gives you finer control over versions, resource limits, and networking. For a homelabber already comfortable with Docker, it is the natural choice.

Next steps from here:

Set up Nginx Proxy Manager to expose Home Assistant securely with HTTPS
Deploy Cloudflare Tunnel for remote access without opening ports
Choose the best NAS OS for storing Home Assistant backups, media, and camera footage
Monitor your entire homelab with Grafana and Prometheus — track CPU, RAM, and disk usage of your Home Assistant host
Run Ollama on Proxmox to add local AI-powered voice assistants to your smart home

Happy automating — and remember: permit_join: false.

Nginx Proxy Manager Docker Compose: The Beginner’s Guide to Homelab Reverse Proxies

2026-06-06T00:00:00+07:00

Reading time: ~14 minutes Audience: Homelabbers who want clean domains and HTTPS for all their Docker services

Why You Need a Reverse Proxy

You’ve got 10 Docker containers running — Nextcloud on port 8080, Pi-hole on port 8180, Portainer on port 9443 — and you’re typing http://192.168.1.50:32400 to access Plex. Every service has a different port, you have no HTTPS, and your browser keeps screaming “Not Secure.” There’s a better way.

A reverse proxy sits at the edge of your network, receives all incoming requests, and routes them to the correct backend service. Instead of memorizing ports, you access cloud.yourdomain.com, admin.yourdomain.com, and photos.yourdomain.com — all on standard port 443 with valid SSL certificates.

Nginx Proxy Manager (NPM) is the most beginner-friendly reverse proxy for homelab use. It wraps the powerful Nginx engine in a clean web GUI. No configuration files to edit. No CLI flags to memorize. Let’s Encrypt integration is built-in — one click and you have HTTPS.

By the end of this guide, you’ll have:

A running Nginx Proxy Manager instance on Docker
Custom subdomains for all your services (*)
Auto-renewing free SSL certificates from Let’s Encrypt
Portainer integration for easy stack management

What Is Nginx Proxy Manager?

Overview

Nginx Proxy Manager is an open-source web interface for managing Nginx reverse proxy hosts. It was created by Jamie Curnow (jc21) and has grown to over 33,000 GitHub stars. The goal: make Nginx accessible to people who don’t want to write config files.

Instead of hand-editing nginx.conf blocks, you fill in a web form: domain name, backend IP and port, select SSL options — done. The GUI updates Nginx configuration automatically and reloads the service.

Key Features

Feature	Description
GUI Proxy Host Manager	Add, edit, and delete proxy hosts through a web dashboard
Automatic Let’s Encrypt SSL	HTTP and DNS challenge support; wildcard certificates
Access Lists	IP-based allow/deny rules for individual proxy hosts
404 Redirects	Custom landing pages for unconfigured subdomains
Stream Proxies	Proxy raw TCP/UDP streams (ideal for game servers, SSH)
Custom Nginx Snippets	Inject raw Nginx config for advanced headers, CORS, or WebSocket
Let’s Encrypt Auto-Renewal	Certificates renew automatically every 60 days
Docker Healthcheck	Built-in health status endpoint

NPM vs Traefik vs Caddy: Which Reverse Proxy?

NPM isn’t the only reverse proxy for homelab use. Here’s how the three main contenders compare:

Feature	Nginx Proxy Manager	Traefik	Caddy
GUI	✅ Full web UI	❌ Config files only	❌ Config files only
Learning curve	Low	High	Medium
Docker auto-discovery	❌ Manual setup	✅ Native Docker label discovery	❌ Manual (or Caddy-Docker-Proxy plugin)
Let’s Encrypt	Built-in (+ DNS Challenge)	Built-in	Built-in (automatic)
Configuration syntax	Web form	YAML / labels	Caddyfile (simple DSL)
Stream proxy (TCP/UDP)	✅	✅	✅ (Caddy L4)
Best for	Beginners, mixed teams, quick setup	Kubernetes, Docker Swarm, auto-scaling	Developers who like Caddyfile simplicity
GitHub Stars	33k+	55k+	60k+

When to pick NPM: You want a GUI, you’re managing a handful of services, you don’t need automatic Docker container discovery, and you want to stop editing config files.

When to pick Traefik: You run dozens of containers, want auto-discovery via Docker labels, and are comfortable with YAML configuration.

When to pick Caddy: You like a simple config language (Caddyfile), want automatic HTTPS with zero configuration, and don’t need a web GUI.

For 90% of homelabbers, Nginx Proxy Manager is the right choice. It’s fast to set up, forgiving of mistakes, and the GUI means you’ll actually remember how it works when you come back to it six months later.

Prerequisites

Hardware Requirements

Any x86_64 or ARM64 device running Docker (mini PC, Raspberry Pi 4/5, Proxmox LXC, or old laptop)
512MB RAM minimum (1GB recommended)
2GB storage for configuration and certificate data

Software Requirements

Docker Engine 24.x+ with Docker Compose v2+
Linux host (Debian 12, Ubuntu 22.04/24.04, or Proxmox LXC)
Firewall rules allowing ports 80 and 443 (if using HTTP challenge or public access)

Networking Requirements

A domain name (e.g., from Cloudflare, Namecheap, or Porkbun) — or local DNS via Pi-hole for internal-only use
DHCP reservation or static IP for your Docker host
Ports 80 and 443 forwarded on your router (if exposing services publicly) — or use Cloudflare Tunnel to skip port forwarding entirely

Step 1: Create the Docker Compose File

First, create a dedicated directory and the compose file:

mkdir -p ~/nginx-proxy-manager && cd ~/nginx-proxy-manager

Create docker-compose.yml:

version: '3.8'

services:
  nginx-proxy-manager:
    image: jc21/nginx-proxy-manager:latest
    container_name: npm
    restart: unless-stopped          # Auto-restart on crash or host reboot
    ports:
      - "80:80"                       # HTTP — Let's Encrypt HTTP challenge
      - "443:443"                     # HTTPS — secure traffic to your services
      - "81:81"                       # Admin web UI (accessible at http://host:81)
    volumes:
      - ./data:/data                  # NPM configuration (proxy hosts, SSL certs, settings)
      - ./letsencrypt:/etc/letsencrypt # Let's Encrypt certificate storage
    environment:
      - DISABLE_IPV6=true             # Set to false if you use IPv6
    networks:
      - npm_network                   # Custom bridge for inter-container communication
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:81"]
      interval: 30s
      timeout: 10s
      retries: 3

networks:
  npm_network:
    driver: bridge                    # Isolated network for NPM + your services

What each piece does:

jc21/nginx-proxy-manager:latest — Official upstream image from the project’s Docker Hub, maintained by the NPM creator.
restart: unless-stopped — Ensures NPM comes back up after a power outage or host reboot.
Port 81 — The admin dashboard. Change the host port if 81 is already in use (e.g., "8081:81").
npm_network — A custom Docker bridge network. All containers you want NPM to reach must join this same network. Without it, NPM can’t resolve container names.
healthcheck — Docker checks the admin UI every 30 seconds. The container status in docker ps reflects actual health, not just “running.”

⚠️ Important: If you’re running Pi-hole or another service that binds port 80, stop it first. NPM must own ports 80 and 443. Pi-hole can use alternative ports — adjust its compose file to map "8180:80" and "8143:443".

Step 2: Deploy and Log In

Start the stack:

docker compose up -d

Check that it’s running:

docker compose ps

You should see npm with status “healthy” after a few seconds.

Open your browser and navigate to http://[your-host-ip]:81. Log in with the default credentials:

Email: admin@example.com
Password: changeme

Change the password immediately. Click your email address in the top-right corner → Edit Details → enter your full name, a real email address, and a strong password.

🛡️ Security tip: Change the default admin email to a real one. Let’s Encrypt sends expiration warnings to this email address. If you leave it as admin@example.com, you’ll never get renewal failure alerts.

Dashboard Overview

Section	Purpose
Proxy Hosts	Main view — add and manage domain-to-backend mappings
Redirection Hosts	HTTP-to-HTTPS redirects or domain-to-other-domain redirects
Streams	Raw TCP/UDP forwarding (SSH, game servers, RTMP)
404 Hosts	Custom “page not found” landings for unknown subdomains
SSL Certificates	Request, renew, and manage Let’s Encrypt certificates
Access Lists	IP-based allow/deny rules you can attach to proxy hosts
Users	Create additional admin or viewer accounts
Audit Log	See who changed what and when

Step 3: Add Your First Proxy Host

Let’s expose a service at a clean subdomain. We’ll use a Nextcloud container as an example — assume it’s running on the same Docker host with container name nextcloud, listening on port 80 internally.

Make sure Nextcloud is on the same Docker network. Attach it to npm_network:

docker network connect npm_network nextcloud

Or, better, define the network in every service’s docker-compose.yml:

# In your Nextcloud's docker-compose.yml:
networks:
  npm_network:
    external: true   # Use the pre-existing NPM network

Now, in the NPM admin dashboard:

Click Proxy Hosts → Add Proxy Host
Domain Names: cloud.yourdomain.com
Scheme: http
Forward Hostname / IP: nextcloud (Docker container name resolves automatically on the shared bridge network)
Forward Port: 80 (the port inside the container, not the host-mapped port)
Cache Assets: Leave off (Nextcloud handles its own caching)
Block Common Exploits: ✅ Enable this — it’s a one-click SQL injection and path traversal guard
Websockets Support: Enable if the app requires live updates (Portainer, Home Assistant, Immich, Uptime Kuma)
Click Save

You can now access http://cloud.yourdomain.com and NPM routes traffic to Nextcloud. No port number needed.

Enabling WebSockets for Real-Time Apps

Some apps need WebSocket connections to function properly. If you see “Connection lost” or blank dashboards, enable Websockets Support in the Advanced tab of that proxy host entry.

App	Needs WebSockets?
Portainer	✅ Yes (live container logs)
Home Assistant	✅ Yes (real-time state updates)
Uptime Kuma	✅ Yes (monitor status pulses)
Immich	✅ Yes (live photo uploads)
Grafana	✅ Yes (dashboard refresh)
Nextcloud	❌ No (standard HTTP is fine)
Pi-hole	❌ No
Plex / Jellyfin	❌ No

Custom Nginx Location Snippets

For advanced setups, the Advanced tab lets you paste raw Nginx directives. This is useful for:

# Override upload size limit (Nextcloud needs this)
client_max_body_size 10G;

# Add security headers
add_header X-Frame-Options "SAMEORIGIN" always;
add_header X-Content-Type-Options "nosniff" always;
add_header Referrer-Policy "strict-origin-when-cross-origin" always;

# Allow Home Assistant ingress
proxy_buffering off;

Step 4: Enable Free SSL with Let’s Encrypt

HTTP is fine for testing, but production services need HTTPS. Nginx Proxy Manager makes SSL certificates dead simple with two challenge options.

Option A: HTTP Challenge (Simplest, Requires Port 80 Forwarded)

Go to your proxy host → SSL tab
Select Request a new SSL Certificate
Choose HTTP Challenge
Enter your email address (for Let’s Encrypt expiry alerts)
Agree to the Let’s Encrypt Terms of Service
Click Save

NPM handles the ACME challenge, fetches the certificate, and auto-reloads Nginx. Your service now responds on https://cloud.yourdomain.com.

Option B: DNS Challenge (Better — Works Without Public Ports, Supports Wildcards)

DNS Challenge is the preferred method because:

It works even if your ISP blocks ports 80/443
You can request wildcard certificates (*.yourdomain.com) and use one cert for all subdomains
No HTTP listener needed on the public internet

Step-by-step for Cloudflare:

Go to Cloudflare Dashboard → your domain → API Tokens
Create a token with permissions: Zone:Read + DNS:Edit for your zone
Copy the token

Back in NPM:

Navigate to SSL Certificates → Add SSL Certificate → Let’s Encrypt
Enter *.yourdomain.com and yourdomain.com in the Domain Names field (wildcard + apex)
Select Use a DNS Challenge
Choose Cloudflare as the DNS provider
Paste your API token into the credentials field
Agree to the Terms of Service
Click Save

NPM creates a TXT record in your Cloudflare DNS, validates it with Let’s Encrypt, and stores the wildcard certificate. This process takes about 15 seconds.

Now apply it: go back to any proxy host → SSL tab → select your new *.yourdomain.com certificate from the dropdown → Save.

Force SSL (HTTP → HTTPS Redirect)

In the SSL tab of each proxy host, enable Force SSL. This adds an automatic HTTP-to-HTTPS redirect so nobody accidentally uses the insecure URL.

Certificate Auto-Renewal

NPM automatically attempts renewal 30 days before expiry. Renewals use the same challenge method as the original request. If a renewal fails, NPM logs the error and retries daily. Let’s Encrypt also sends expiry warnings to the email you provided.

# Check renewal logs
docker logs npm 2>&1 | grep -i "renew"

Step 5: Integrate with Portainer (Optional)

If you run Portainer for container management, you can deploy NPM as a Portainer stack for a unified workflow.

In Portainer:

Go to Stacks → Add Stack
Name: npm
Paste the docker-compose.yml from Step 1
Under Network, ensure the stack is attached to an external network (npm_network)
Click Deploy the stack

Portainer now shows NPM’s container status, logs, and resource usage in one dashboard. You can restart or update NPM without touching the CLI.

For services managed via Portainer stacks, add them to the NPM network by editing their stack’s compose file:

networks:
  default:
    name: npm_network
    external: true

This ensures every service in the stack can be reached by NPM via its container name.

💡 Pro tip: Keep NPM in its own stack, separate from your application stacks. This way, you can restart or update services without affecting the reverse proxy.

Troubleshooting FAQ

Q: “502 Bad Gateway” when I try to access my service

This is the most common error and almost always means NPM can’t reach the backend container.

Checklist:

Are both containers on the same Docker network? Run docker network inspect npm_network and confirm both containers are listed.
Is the Forward Port correct? Use the internal container port (e.g., 80), not the host-mapped port (e.g., 8080).
Is the container actually running? docker ps | grep your-container
Can NPM resolve the container name? Try docker exec npm ping nextcloud — if it fails, they’re not on the same network.
Use the IP address instead of container name temporarily: docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' nextcloud

Q: My SSL certificate shows as invalid or expired

Check the NPM logs: docker logs npm 2>&1 | grep -i "error\|ssl\|cert"
For DNS challenges: verify the API token still has Zone:Read and DNS:Edit permissions
For HTTP challenges: verify port 80 is accessible from the internet (use canyouseeme.org)
Force manual renewal: in SSL Certificates → click the three-dot menu → Renew Now
Check the email address on your SSL certificate entry — Let’s Encrypt sends warnings to it

Q: WebSockets not working for Portainer / Home Assistant

In the proxy host’s Advanced tab, you need both the WebSockets Support toggle and sometimes additional headers:

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;

Q: Can’t access NPM admin panel on port 81

Check if another service is using port 81: sudo lsof -i :81
Verify your firewall: sudo ufw status — if UFW is active, allow port 81: sudo ufw allow 81
If the host firewall is iptables-based, check Docker’s rules: sudo iptables -L DOCKER
Try mapping a different port in docker-compose.yml: change "81:81" to "8181:81"

Q: Do I need NPM if I use Cloudflare Tunnel?

They solve different problems:

Cloudflare Tunnel securely exposes your services to the public internet without opening router ports. It runs as a daemon on your server and proxies traffic through Cloudflare’s edge.
Nginx Proxy Manager routes traffic within your LAN and provides local HTTPS with custom domains.

Real-world combo: Use Cloudflare Tunnel for public access (cloud.yourdomain.com from anywhere), and NPM for local access (cloud.home) — both pointing at the same backend containers. Best of both worlds.

Q: How do I back up my NPM configuration?

Back up two directories:

# Stop NPM first (optional but safer)
docker compose down

# Copy the data and certificate volumes
sudo cp -r ~/nginx-proxy-manager/data ~/backups/npm-data-$(date +%Y%m%d)
sudo cp -r ~/nginx-proxy-manager/letsencrypt ~/backups/npm-letsencrypt-$(date +%Y%m%d)

# Restart
docker compose up -d

Restoring is the reverse: copy the directories back and start the container. NPM picks up all proxy hosts and SSL certificates automatically.

Q: Can I use NPM for local-only services (no public domain)?

Yes. Use Pi-hole or AdGuard Home for local DNS:

In Pi-hole: Local DNS → DNS Records
Add: cloud.home → 192.168.1.50 (your Docker host IP)
In NPM: add a proxy host for cloud.home pointing at your container
Request an SSL certificate using DNS Challenge (no public port 80 needed)

This gives you valid HTTPS for internal-only services — even on .home or .local domains — using DNS Challenge with Cloudflare or DuckDNS.

Self-Hosted Media Server 2026: Jellyfin vs Plex vs Emby — The Complete Homelab Guide

Reading time: ~16 minutes Audience: Homelab owners building their first media server stack

Introduction: Why Self-Host Your Media in 2026?

Streaming subscriptions have become cable TV in disguise. Between Netflix ($17.99), Disney+ ($15.99), Max ($16.99), Hulu ($18.99), and a half-dozen others, the monthly bill easily crosses $100 — and you still do not own anything. Shows vanish overnight when licensing deals expire. Regional restrictions block content you paid for. And every platform now injects ads into their “ad-free” tiers.

Building a self-hosted media server solves all three problems: you own your media, you control access, and you pay once for hardware that lasts years. A full media server setup — a refurbished mini PC, a couple of 8 TB hard drives, and free open-source software — pays for itself in under 12 months compared to streaming subscriptions. After that, it is pure savings.

In 2026, the self-hosted media server landscape has three clear contenders: Jellyfin (fully open-source and free), Plex (commercial, polished, widely supported), and Emby (the middle ground with an open core and optional premium). This guide compares all three — something no other article does — with real Docker Compose files you can copy and paste, hardware transcoding requirements for 4K streaming, and a decision tree that tells you which to pick in under a minute.

The Three Contenders at a Glance

Feature	Jellyfin	Plex	Emby
License	GPL (fully open-source)	Proprietary (freemium)	Proprietary (open-core)
Cost	Completely free	Free base; Plex Pass $6.99/mo	Free base; Emby Premiere $4.99/mo
Cloud dependency	None — fully local	Required for authentication	Optional (local auth available)
Hardware transcoding	Free (VAAPI, QSV, NVENC)	Requires Plex Pass	Requires Emby Premiere
Client apps	Good (Android, iOS, web, Roku, Apple TV)	Excellent (every platform)	Very good (most platforms)
Plugin ecosystem	Growing community plugins	Official channels + agents	Plugin catalog
Live TV / DVR	Free (HDHomeRun, m3u)	Plex Pass required	Emby Premiere required
User management	Built-in, no limits	Built-in, managed users free	Built-in
Mobile sync/download	Not native (3rd-party)	Plex Pass required	Emby Premiere required

The short version: pick Jellyfin if you want everything free and do not mind occasional rough edges. Pick Plex if you want Netflix-like polish and are willing to pay for premium features. Pick Emby if you want more customization than Plex but better app support than Jellyfin.

Deep Dive: How Each Platform Works

Jellyfin — The Open-Source Purist

Jellyfin is a fork of Emby 3.5.2, created in December 2018 when Emby closed its source code. Since then, the Jellyfin community has built a fully open-source media server under the GPL license. There is no premium tier, no paywall, and no cloud authentication server phoning home. Everything runs locally on your hardware.

Jellyfin’s plugin ecosystem is community-driven and covers metadata fetching (TheMovieDB, TheTVDB, OpenSubtitles), client-side features (Kodi Sync, Intro Skipper), and advanced tools (Bookshelf for ebooks, Tautulli-style analytics). Hardware transcoding works out of the box with Intel Quick Sync (QSV), AMD VAAPI, and NVIDIA NVENC — no license key required.

The trade-off: Jellyfin’s client apps, while solid, are not as polished as Plex. The Apple TV app is community-maintained (Swiftfin). The Roku app occasionally lags behind the web client in features. For power users comfortable with a bit of rough-around-the-edges software, Jellyfin is the obvious choice. It is the only option that respects your privacy unconditionally.

Plex — The Polished Commercial Option

Plex is the most mature media server platform, with over 15 years of development. It offers a freemium model: the core server and playback are free, but premium features — hardware transcoding, Live TV/DVR, mobile sync, skip intro, and Plexamp — require a Plex Pass subscription ($6.99/month, $39.99/year, or $149.99 lifetime).

Plex’s biggest strength is its client app ecosystem. There is a native app for every device imaginable: every smart TV platform, every streaming stick, every game console, and every mobile OS. The Plexamp music player is genuinely excellent. Plex’s metadata matching is best-in-class, and the discovery features (AI-powered recommendations, “Plex Discover” universal watchlist, cross-service search) feel like a commercial streaming service.

The trade-off: Plex requires cloud authentication for user sign-in. When Plex’s auth servers go down — and they do, a few times a year — you cannot sign into your own server. The mobile apps require a one-time $5.99 activation fee (or Plex Pass) for full playback. And Plex has been gradually layering in their own ad-supported content, which purists find distasteful on a self-hosted server.

Emby — The Middle Ground

Emby occupies the space between Jellyfin’s open-source purity and Plex’s commercial polish. Its core server is proprietary but exposes enough configuration for power users. Emby Premiere ($4.99/month, $54/year, or $149 lifetime) unlocks hardware transcoding, Live TV/DVR, mobile sync, cover art customization, and Cinema Intros — roughly equivalent to Plex Pass at a slightly lower subscription price.

Emby’s unique strengths: local authentication is a first-class feature (unlike Plex), the metadata manager is more flexible than Plex’s, and the plugin architecture supports deeper customization. Emby also has better parental controls than Jellyfin and a more configurable home screen layout. Client support covers all major platforms, though the app ecosystem is smaller than Plex.

The trade-off: Emby’s community is the smallest of the three. Fewer plugins, fewer third-party tools, and fewer community-written guides exist compared to Jellyfin or Plex. Documentation quality varies. And like Jellyfin, the premium features are behind a paywall — though unlike Plex, Emby does not require cloud authentication.

Hardware Transcoding: What Your Homelab Needs

Hardware transcoding converts video from one format to another in real time using a GPU or integrated graphics. Without it, the CPU must handle transcoding in software, which is slow and power-hungry. For a single 1080p stream, any modern CPU handles software transcoding fine. For 4K HDR with tone mapping, hardware transcoding is mandatory.

CPU Requirements Per Stream

Stream Type	Software (CPU only)	Hardware (GPU/iGPU)
1080p → 1080p	~2,000 PassMark per stream	Minimal GPU usage
1080p → 720p	~1,500 PassMark per stream	Minimal GPU usage
4K → 1080p (SDR)	~12,000 PassMark per stream	Intel QSV or NVIDIA NVENC
4K HDR → 1080p SDR (tone mapping)	~17,000 PassMark per stream	Intel QSV (7th-gen+) or NVIDIA 1050+

A practical example: an Intel Core i3-12100 (PassMark ~13,400) can handle roughly one 4K software transcode or 6+ 1080p software transcodes. Add Intel Quick Sync, and that same i3-12100 handles 4-5 simultaneous 4K HDR-to-1080p SDR transcodes with tone mapping — a 5x improvement.

GPU/iGPU Recommendations for Hardware Transcoding

Hardware	Transcode Engine	4K Performance	Best For
Intel Quick Sync (7th-gen+)	QSV	4-8 simultaneous 4K transcodes	Most homelab builds; free with Intel CPU
Intel Arc A310/A380	QSV (discrete)	8+ simultaneous 4K transcodes	Dedicated transcoding box; AV1 encode
NVIDIA GTX 1050 Ti+	NVENC	3-5 simultaneous 4K transcodes	Existing gaming GPU reuse
NVIDIA Quadro P400	NVENC	2-3 simultaneous 4K transcodes	Low-power, no external power needed
AMD Ryzen APU (Vega)	VCN	1-2 simultaneous 4K transcodes	Budget builds; Linux VAAPI support improving

The homelab sweet spot: An Intel N100 mini PC (~$150) with Quick Sync handles 2-3 simultaneous 4K transcodes while drawing 6W idle. Pair it with a NAS for storage, and you have a media server that rivals a $2,000 prebuilt NAS in transcoding capability.

Docker Compose Setup: Get Running in 10 Minutes

All three media servers run beautifully in Docker. The key is passing through the hardware transcoding device (/dev/dri) and mapping your media directories correctly.

Jellyfin Docker Compose

version: '3.8'
services:
  jellyfin:
    image: jellyfin/jellyfin:latest
    container_name: jellyfin
    restart: unless-stopped
    network_mode: host  # Simplifies DLNA and discovery
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Asia/Jakarta
    volumes:
      - ./config:/config
      - ./cache:/cache
      - /mnt/media/tv:/data/tvshows
      - /mnt/media/movies:/data/movies
      - /mnt/media/music:/data/music
    devices:
      - /dev/dri:/dev/dri  # Intel Quick Sync hardware transcoding
    # For NVIDIA GPUs, add:
    # deploy:
    #   resources:
    #     reservations:
    #       devices:
    #         - driver: nvidia
    #           count: 1
    #           capabilities: [gpu]

After docker compose up -d, Jellyfin is available at http://your-server-ip:8096. Complete the setup wizard, add your media libraries, and enable hardware transcoding under Dashboard → Playback → Hardware Acceleration → Intel Quick Sync (QSV).

Plex Docker Compose

version: '3.8'
services:
  plex:
    image: lscr.io/linuxserver/plex:latest
    container_name: plex
    restart: unless-stopped
    network_mode: host
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Asia/Jakarta
      - VERSION=docker
      - PLEX_CLAIM=claim-xxxxxxxxxxxxx  # Get from https://plex.tv/claim
    volumes:
      - ./config:/config
      - /mnt/media/tv:/tv
      - /mnt/media/movies:/movies
      - /mnt/media/music:/music
    devices:
      - /dev/dri:/dev/dri

Important: PLEX_CLAIM is a one-time token that links your server to your Plex account. It expires in 4 minutes — generate it at plex.tv/claim right before running docker compose up -d. The claim token is only needed for first-run; remove it after setup.

Plex is available at http://your-server-ip:32400/web. Hardware transcoding is enabled under Settings → Transcoder → Use hardware acceleration when available — but remember, this requires Plex Pass.

Emby Docker Compose

version: '3.8'
services:
  emby:
    image: emby/embyserver:latest
    container_name: emby
    restart: unless-stopped
    network_mode: host
    environment:
      - UID=1000
      - GID=1000
      - GIDLIST=1000,44,109  # 44=video, 109=render for hardware transcoding
      - TZ=Asia/Jakarta
    volumes:
      - ./config:/config
      - /mnt/media/tv:/mnt/share1
      - /mnt/media/movies:/mnt/share2
      - /mnt/media/music:/mnt/share3
    devices:
      - /dev/dri:/dev/dri

Emby is available at http://your-server-ip:8096. The GIDLIST environment variable includes group IDs for video (44) and render (109), which are required for hardware transcoding access on Linux. Enable hardware transcoding in Settings → Transcoding → Enable hardware acceleration. Requires Emby Premiere.

Reverse Proxy Integration

Once your media server is running, you probably want to access it with a proper domain. Here is an example Nginx Proxy Manager (NPM) config:

Domain: jellyfin.yourdomain.com
Scheme: http
Forward IP: 192.168.1.50
Forward Port: 8096
SSL: Request Let’s Encrypt certificate
WebSocket Support: Enable (required for playback progress reporting)

If you are using Cloudflare Tunnel instead of port forwarding, add a public hostname pointing to http://localhost:8096 inside the cloudflared configuration. See our Cloudflare Tunnel guide for the full walkthrough. For detailed NPM configuration, refer to our Nginx Proxy Manager tutorial.

4K Streaming & Real-World Performance

4K is where media servers earn their keep. Direct Play — streaming without any transcoding — is the ideal path: the client device decodes the original file, and the server does almost no work. A Raspberry Pi 4 can Direct Play 4K to a modern smart TV all day.

The challenge is transcoding: when the client cannot play the original format (wrong codec, insufficient bandwidth, burned subtitles), the server must convert the stream in real time.

Bandwidth Requirements

Quality	Direct Play (per stream)	Transcode Target
4K Blu-ray remux	60-100 Mbps	—
4K streaming (web-dl)	25-40 Mbps	—
4K → 1080p (10 Mbps)	—	~10 Mbps
1080p Blu-ray remux	25-35 Mbps	—
1080p streaming	8-15 Mbps	—

Network recommendation: Gigabit Ethernet (1 Gbps) for your media server and any wired clients. A single 4K remux (~80 Mbps average, bursting higher) will saturate a 100 Mbps link. For Wi-Fi clients, ensure a strong 5 GHz signal and expect occasional buffering on high-bitrate 4K files. If you are setting up your homelab network, invest in a managed switch with at least Gigabit ports on every link.

Jellyfin-Specific: Tone Mapping

Jellyfin’s 4K HDR-to-SDR tone mapping is entirely free and works with Intel Quick Sync on 7th-gen CPUs and newer, plus NVIDIA GPUs. This is a massive advantage over Plex and Emby, both of which gate hardware tone mapping behind their premium tiers.

Remote Access: How to Stream from Anywhere

Once your media server is running locally, the next question is how to access it outside your home.

Method	Security	Complexity	Best For
WireGuard / Tailscale VPN	Excellent	Low	You + a few trusted users; no public exposure
Cloudflare Tunnel	Very good	Low	Public access without opening ports; HTTPS included
Reverse proxy + Let’s Encrypt	Good	Medium	Full public access with domain + SSL
Port forwarding	Poor	Low	Last resort; exposes your home IP

For the privacy-focused approach, install Tailscale on your media server and every client device. You get encrypted WireGuard tunnels, a private IP range (100.x.x.x), and zero ports exposed to the internet. Tailscale’s free plan supports up to 100 devices.

For sharing with family members who are not technical, use Cloudflare Tunnel. It creates an outbound-only connection from your homelab to Cloudflare’s edge — no open ports, no DDNS, and free SSL. Combine it with Cloudflare Access policies to require a one-time email code or Google login before anyone reaches your server. Our Cloudflare Tunnel guide covers the full setup.

Decision Tree: Which Media Server Is Right for You?

Answer these questions to find your match in under a minute:

Do you want everything completely free and are willing to accept slightly less polished client apps? → Jellyfin. Free hardware transcoding, free Live TV/DVR, no cloud dependency, no accounts to create. The open-source purist’s choice.
Do you want the closest thing to a self-hosted Netflix with the best apps on every device, and are you okay paying for premium features? → Plex. Pay for Plex Pass ($149 lifetime is the best value), and you get a polished experience that your family will actually use without complaining.
Do you want more customization than Plex, better app support than Jellyfin, and the option to keep authentication fully local? → Emby. Emby Premiere ($149 lifetime) unlocks hardware transcoding. The middle ground that many homelabbers overlook — but should not.

Still undecided? You do not have to choose just one. Many homelabbers run Jellyfin as their primary server and keep Plex installed for the rare family member who insists on the Plex app. Both can point at the same media directories. Try Jellyfin first — it is free and takes 10 minutes with the Docker Compose file above. If you hit a wall with client support, try Plex or Emby alongside it.

FAQ

Can I migrate from Plex to Jellyfin? Yes — and it is surprisingly easy. Both servers read the same media files. Your watch history is the main thing that does not transfer. Use the community tool Jellyfin-Plex-Trakt-Sync to sync watch status via Trakt.tv as a bridge. For metadata, Jellyfin rescans your libraries and fetches cover art, descriptions, and cast information from the same sources Plex uses (TheMovieDB, TheTVDB).

Does Jellyfin work on Apple TV? Yes, via the Swiftfin app (community-maintained, free, App Store). It handles Direct Play beautifully and supports 4K HDR. Transcoding-heavy use cases may encounter occasional issues. An official Jellyfin Apple TV app is in development but not yet released.

Is hardware transcoding really free on Jellyfin? Yes. Completely. Jellyfin includes VAAPI, Intel Quick Sync, NVIDIA NVENC, and AMD VCN hardware acceleration with no license, no subscription, and no activation required. This alone saves you $149 (Plex Pass lifetime) or $149 (Emby Premiere lifetime). Jellyfin’s HDR-to-SDR tone mapping is also free — a feature both competitors paywall.

Can I run multiple media servers on the same hardware? Absolutely. Point Jellyfin, Plex, and Emby at the same media directories. As long as each runs on a different port (8096, 32400, 8096 respectively — note Jellyfin and Emby default to the same port, so change one), they coexist without conflict. This is common in the homelab community: run Jellyfin as the daily driver, keep Plex installed for testing or for a family member who insists on the Plex app.

Conclusion

Jellyfin, Plex, and Emby each serve a distinct audience within the homelab community. Jellyfin delivers a fully open-source, zero-cost media server that respects your privacy absolutely — at the cost of slightly rougher client apps. Plex offers a polished, Netflix-like experience across every device imaginable, backed by 15 years of development — but locks its best features behind a paywall and requires cloud authentication. Emby strikes a middle ground with local auth, flexible customization, and solid app support — but has the smallest community.

No matter which you choose, Docker Compose makes setup trivially easy. Copy the docker-compose.yml above, set your media paths, run docker compose up -d, and you have a media server in under 10 minutes. Pair it with a low-power mini PC for always-on operation, store your media on a proper NAS OS, and secure remote access with Cloudflare Tunnel or Tailscale.

The $100/month streaming bill ends today. Your self-hosted media server starts now.

Best European VPS for Homelab 2026: Self-Hosting on EU Servers

2026-06-05T00:33:00+07:00

Reading time: ~14 minutes
Audience: Homelab users who need an offsite VPS for public-facing services, backups, or VPN endpoints
Last updated: June 2026

Why Use a European VPS for Your Homelab?

Overview

A European VPS bridges the gap between your local homelab and the public internet. It gives you a static IP, DDoS protection, and reliable uptime for services that cannot run behind a residential NAT or dynamic IP. Common homelab VPS use cases include:

Public reverse proxy / tunnel: Expose local services through a VPS with a stable IP (e.g., FRP, WireGuard reverse tunnel, Cloudflare Tunnel)
Offsite backup target: Run Restic, BorgBackup, or rsync.net-compatible storage
Mail server relay: Host your own email without risking your residential IP reputation
Monitoring beacon: Uptime Kuma or Nagios checking your home services from outside
VPN hub: WireGuard or Tailscale coordination server for road-warrior access

Pro Tips

Tip 1: Use ARM Instances Where Possible

Hetzner’s CAX11 (ARM Ampere Altra) is €3.29 for 2 vCPU / 4 GB RAM. Most self-hosted apps (Docker, Nextcloud, Pi-hole, WireGuard) have ARM64 images. You save money and get better power efficiency.

Tip 2: Combine VPS with Local Homelab

Use the VPS as a public edge node and keep heavy storage/CPU workloads local: - VPS: WireGuard hub + reverse proxy + public DNS - Homelab: Jellyfin transcode + ZFS NAS + Proxmox cluster

Tip 3: Watch for Black Friday Deals

Netcup and Contabo run aggressive seasonal promotions. Hetzner rarely discounts but occasionally waives setup fees. Set calendar reminders for November.

Conclusion

Summary

For most homelab users, Hetzner offers the best balance of price, performance, and automation. If you need massive traffic quotas, Netcup is the runner-up. For DDoS-protected public services, consider OVHcloud. Contabo wins on raw specs if you can tolerate shared CPU, and Ionos is the safe, supported choice.

Docker Compose for Beginners: A Step-by-Step Homelab Guide 2026

2026-06-05T00:33:00+07:00

What Is Docker Compose?

Overview

Docker Compose is a tool that lets you define and run multi-container applications using a single YAML file (docker-compose.yml). Instead of running long docker run commands with dozens of flags, you declare your entire stack — services, networks, volumes, and environment variables — in one readable file.

For homelab users, Compose is the standard way to deploy self-hosted apps like Nextcloud, Immich, Jellyfin, Pi-hole, and Portainer. A typical homelab runs 10–30 containers orchestrated through Compose files.

Prerequisites

Hardware Requirements

Setup	RAM	Storage	Notes
Minimal (5–10 containers)	2 GB	20 GB SSD	Intel N100, Raspberry Pi 5, or old laptop
Comfortable (15–30 containers)	4–8 GB	64 GB SSD	Recommended for most homelabs
Heavy (30+ with databases)	16 GB+	256 GB NVMe	Include swap or ZFS compression

Software Requirements

Docker Engine 24.0+ and Docker Compose plugin v2.20+
A Linux distribution: Ubuntu 22.04/24.04 LTS, Debian 12, or Proxmox LXC (privileged or with nesting enabled)

Knowledge Prerequisites

Basic Linux command line (SSH, cd, ls, nano or vim)
Understanding of YAML indentation (spaces, not tabs)
A static IP or local DNS name for your server

Step 1: Install Docker and Docker Compose

Objective

Install the official Docker Engine and Compose plugin.

Step-by-Step Instructions

Update your system:

sudo apt update && sudo apt upgrade -y

Install required dependencies:

sudo apt install ca-certificates curl gnupg lsb-release -y

Add Docker’s official GPG key and repository:

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | \
  sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \
  https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Install Docker Engine and Compose:

sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

Add your user to the docker group (log out and back in after):

sudo usermod -aG docker $USER
newgrp docker

Verify:

docker --version
docker compose version

Expected output:

Docker version 26.x.x
Docker Compose version v2.29.x

Step 2: Write Your First docker-compose.yml

Objective

Create a Compose file that runs NGINX and a simple whoami service.

Step-by-Step Instructions

Create a project directory:

mkdir -p ~/compose-demo && cd ~/compose-demo

Create docker-compose.yml:

version: "3.8"

services:
  nginx:
    image: nginx:alpine
    container_name: nginx-demo
    ports:
      - "8080:80"
    volumes:
      - ./html:/usr/share/nginx/html:ro
    restart: unless-stopped

  whoami:
    image: traefik/whoami
    container_name: whoami-demo
    restart: unless-stopped

Create a simple HTML file:

mkdir html
echo "<h1>Hello from Docker Compose!</h1>" > html/index.html

Start the stack:

docker compose up -d

Test:

curl http://localhost:8080

You should see “Hello from Docker Compose!”.

View running containers:

docker compose ps
docker compose logs -f

Step 3: Deploy a Real Homelab Stack (NGINX Proxy Manager + Uptime Kuma)

Objective

Deploy a practical two-app stack with persistent volumes and a custom bridge network.

Step-by-Step Instructions

Create a new directory:

mkdir -p ~/homelab-stack && cd ~/homelab-stack

Create docker-compose.yml:

version: "3.8"

services:
  nginx-proxy-manager:
    image: jc21/nginx-proxy-manager:latest
    container_name: nginx-proxy-manager
    ports:
      - "80:80"
      - "81:81"
      - "443:443"
    volumes:
      - npm-data:/data
      - npm-letsencrypt:/etc/letsencrypt
    restart: unless-stopped

  uptime-kuma:
    image: louislam/uptime-kuma:latest
    container_name: uptime-kuma
    volumes:
      - uptime-data:/app/data
    restart: unless-stopped
    # Access via NPM reverse proxy on port 3001

volumes:
  npm-data:
  npm-letsencrypt:
  uptime-data:

Launch:

docker compose up -d

Access NGINX Proxy Manager at http://your-server-ip:81. Default login:
Email: admin@example.com
Password: changeme
Access Uptime Kuma at http://your-server-ip:3001. Set it up to monitor your homelab services.

Pro Tip: Use NGINX Proxy Manager to give each app a local subdomain (e.g., npm.lan, kuma.lan) instead of remembering port numbers.

Step 4: Understanding Networks and Persistent Storage

Objective

Learn how Compose handles inter-container communication and data persistence.

Step-by-Step Instructions

Default Bridge Network: By default, Compose creates a private network. Services can reach each other by their service name as a hostname:

services:
  db:
    image: mariadb:11
    environment:
      MYSQL_ROOT_PASSWORD: secret
  app:
    image: nextcloud
    environment:
      MYSQL_HOST: db  # Resolves to the MariaDB container

Named Volumes vs Bind Mounts:

Type	Syntax	Best For
Named volume	`volumes: app-data:/var/lib/mysql`	Databases, app state
Bind mount	`./config:/config`	Config files you edit by hand
tmpfs	`type: tmpfs, target: /cache`	Ephemeral cache

Example with both:

services:
  immich:
    image: ghcr.io/immich-app/immich-server:release
    volumes:
      - immich-upload:/usr/src/app/upload          # Named volume
      - /etc/localtime:/etc/localtime:ro            # Bind mount

Step 5: Updating and Maintaining Containers

Objective

Safely update images without losing data.

Step-by-Step Instructions

Navigate to your stack directory:

cd ~/homelab-stack

Pull new images:

docker compose pull

Recreate containers with new images:

docker compose up -d

Compose only restarts containers whose images changed. Named volumes are preserved automatically.

Clean up old images to save disk space:

docker image prune -f

For a full system cleanup (unused volumes, networks, images):

docker system prune -a --volumes

Warning: This deletes unused named volumes. Ensure your data is backed up.

Pro Tips

Tip 1: Use `.env` Files for Secrets

Never commit passwords to Git. Create .env:

DB_PASSWORD=supersecret
DOMAIN=homelab.local

Reference it in docker-compose.yml:

environment:
  MYSQL_ROOT_PASSWORD: ${DB_PASSWORD}

Tip 2: Enable Docker Auto-Start on Boot

sudo systemctl enable docker

Your containers will start automatically after a power outage if they use restart: unless-stopped.

Tip 3: Monitor Disk Usage

Docker can consume GBs of log files. Limit log size per container:

logging:
  driver: "json-file"
  options:
    max-size: "10m"
    max-file: "3"

Tip 4: Use `docker compose -f` for Multiple Files

Split your homelab into logical files:

docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d

Troubleshooting Common Issues

“Permission Denied” on Bind Mounts

Docker runs as root by default. Either: - Set folder ownership to your user UID/GID - Or use named volumes instead of bind mounts

Ports Already in Use

sudo lsof -i :80

Find the conflicting service and change the host port mapping (left side):

ports:
  - "8080:80"  # Host 8080 → Container 80

Container Exits Immediately

Check logs:

docker compose logs <service-name>

Common causes: missing environment variables, wrong architecture (ARM64 vs AMD64), or port conflicts.

Conclusion

Summary

Docker Compose turns complex multi-app deployments into readable, version-controlled YAML files. In this guide, you installed Docker, wrote your first Compose file, deployed a real reverse-proxy stack, and learned how networks and volumes work.

Pi-hole Docker Setup 2026: Network-Wide Ad Blocking for Homelabs

2026-06-05T00:33:00+07:00

Reading time: ~12 minutes
Audience: Beginners who want cleaner browsing and reduced tracking on all home devices
Last tested: Pi-hole FTL v6.0, June 2026

What Is Pi-hole?

Overview

Pi-hole is a DNS sinkhole that blocks advertisements, trackers, and malicious domains at the network level. Instead of installing ad blockers on every browser and device, Pi-hole filters DNS requests for your entire household. Smart TVs, mobile apps, IoT devices, and game consoles all benefit without individual configuration.

Think of it as a “network-wide ad blocker” that runs on a small Linux container and consumes less than 512 MB RAM.

Key Benefits

Benefit	Impact
Network-wide blocking	One setup protects every device on your LAN
Faster page loads	Ads never download, saving bandwidth
Privacy	Blocks trackers that follow you across websites
Malware protection	Known malicious domains are blocked before connection
Parental controls	Block adult content or social media via blocklists
Low resource	Runs on a Raspberry Pi Zero 2 W or Docker container

Prerequisites

Hardware Requirements

Setup	RAM	CPU	Storage	Notes
Minimal (1–2 users)	512 MB	1 core	4 GB	Raspberry Pi Zero 2 W
Standard (5–10 devices)	512 MB	1 core	8 GB	Docker on any Linux host
Heavy (50+ devices, large lists)	1 GB	2 cores	16 GB SSD	Intel N100, old laptop

Software Requirements

Docker Engine and Docker Compose plugin
Access to your router’s admin panel (to change DNS settings)
A Linux host with a static local IP (e.g., 192.168.1.10)

Network Prerequisites

Your Pi-hole host needs a static IP address. If your router uses DHCP, reserve the IP by MAC address.
Port 53 (DNS) must not be in use by another service on the host.

Step 1: Deploy Pi-hole with Docker Compose

Objective

Create a Compose file with persistent storage and the correct network mode.

Step-by-Step Instructions

Create a project directory:

mkdir -p ~/pihole && cd ~/pihole

Create docker-compose.yml:

version: "3.8"

services:
  pihole:
    container_name: pihole
    image: pihole/pihole:2025.07.0  # Pin version for stability
    restart: unless-stopped
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "8080:80/tcp"  # Admin UI; change if 80 is taken
    environment:
      - TZ=Europe/Berlin  # Change to your timezone
      - WEBPASSWORD=changeme  # Strong password for admin UI
      - FTLCONF_LOCAL_IPV4=192.168.1.10  # Your host's static IP
    volumes:
      - ./etc-pihole:/etc/pihole
      - ./etc-dnsmasq.d:/etc/dnsmasq.d
    cap_add:
      - NET_ADMIN
    dns:
      - 127.0.0.1
      - 1.1.1.1

Port 80 conflict: If your host already runs a web server on port 80, map Pi-hole to a different host port (e.g., 8081:80).

Create data directories:

mkdir -p etc-pihole etc-dnsmasq.d

Start Pi-hole:

docker compose up -d

Verify it is running:

docker compose logs -f

Look for “Blocking … domains” and “FTL started”.

Step 2: Point Your Router to Pi-hole

Objective

Redirect all DNS traffic on your network through Pi-hole.

Step-by-Step Instructions

Option A: Router DNS (Recommended)

Log in to your router’s admin panel (usually 192.168.1.1 or 192.168.0.1).
Find the DHCP or LAN settings.
Set the Primary DNS to your Pi-hole IP (e.g., 192.168.1.10).
Set the Secondary DNS to a public resolver like 1.1.1.1 or leave blank (Pi-hole handles upstream).
Save and reboot the router or renew DHCP leases on clients.

Important: If Pi-hole goes down and you set no secondary DNS, devices lose internet access. For redundancy, run a second Pi-hole or use a public DNS as secondary (ads will leak through the secondary, but internet stays up).

Option B: Per-Device DNS

If you cannot change router settings (ISP-locked devices), manually set DNS on each device: - Windows: Network settings → Adapter properties → IPv4 → Preferred DNS: 192.168.1.10 - macOS: System Settings → Network → DNS → Add 192.168.1.10 - Android/iOS: Wi-Fi settings → Advanced → DNS → Add 192.168.1.10

Step 3: Configure Blocklists and Whitelists

Objective

Add aggressive blocklists and fix any broken websites.

Step-by-Step Instructions

Open the Pi-hole admin dashboard:

http://your-server-ip:8080/admin

Navigate to Group Management → Adlists.
Add curated blocklists. Start with these reliable sources:

List Name	URL	Est. Domains
StevenBlack	`https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts`	150,000
OISD Full	`https://dbl.oisd.nl/`	900,000
Firebog Tick lists	`https://v.firebog.net/hosts/lists.php?type=tick`	400,000
AdGuard DNS	`https://v.firebog.net/hosts/AdguardDNS.txt`	50,000

Click Tools → Update Gravity to download and compile the lists.
After updating, check the dashboard for “Total queries” and “Queries blocked”.

Whitelisting broken sites:

Some sites break when critical trackers are blocked (e.g., login callbacks, captchas). If a site fails: 1. Open Pi-hole dashboard → Query Log 2. Find the blocked domain (highlighted in red) 3. Click Whitelist next to it 4. Common whitelists: client-s.gateway.messenger.live, app-analytics-v2.snapchat.com

Step 4: Monitoring and Maintenance

Objective

Understand your dashboard and keep Pi-hole updated.

Step-by-Step Instructions

Dashboard Overview:

Metric	Meaning
Total queries	DNS requests processed
Queries blocked	Requests matching blocklists
Percent blocked	Efficiency ratio (typically 10–30%)
Domains on blocklist	Size of your combined lists
Top permitted domains	Most requested allowed sites
Top blocked domains	Most frequent ads/trackers caught

Updating Pi-hole:

cd ~/pihole
docker compose pull
docker compose up -d

Your blocklists, whitelist, and settings persist in ./etc-pihole.

Updating Gravity (blocklists):

In the web UI: Tools → Update Gravity. Schedule this weekly via cron or the UI’s automatic update option.

Pro Tips

Tip 1: Run Pi-hole in Host Network Mode for IPv6

If your network uses IPv6 extensively, host mode simplifies DNS listening:

    network_mode: host

Remove the ports: block when using host mode.

Tip 2: Use Local DNS Records for Homelab Services

Map local domains to internal IPs so you can access services by name: - Local DNS → DNS Records: - proxmox.lan → 192.168.1.5 - nas.lan → 192.168.1.20

This works across all devices without editing individual /etc/hosts files.

Tip 3: Conditional Forwarding for Reverse DNS

If you run Active Directory or want hostname resolution for local IPs: - Settings → DNS → Conditional Forwarding: - Router IP: 192.168.1.1 - Local domain name: lan

Tip 4: Teleporter Backups

Pi-hole includes a built-in backup/restore tool: - Settings → Teleporter - Export your entire config (lists, whitelist, local DNS, groups) - Store the .tar.gz in your backup system

Troubleshooting Common Issues

“DNS_PROBE_FINISHED_BAD_CONFIG” on Clients

Pi-hole is not reachable. Verify the container is running: docker compose ps
Check firewall rules: port 53/udp and 53/tcp must be open
Ensure the Pi-hole host IP is correct in router DNS settings

YouTube Ads Still Appearing

YouTube serves ads from the same domains as videos (googlevideo.com). DNS blocking cannot distinguish them.
For YouTube ads, use a browser extension (uBlock Origin) or a client-side solution like SmartTube on Android TV.

Dashboard Shows 0 Queries

Your devices are not using Pi-hole as their DNS. Double-check router settings or per-device DNS configuration.
Restart devices to renew DHCP leases with the new DNS server.

Conclusion

Summary

You now have Pi-hole running in Docker, filtering ads and trackers for every device on your network. Your browsing is faster, your privacy is improved, and your IoT devices are no longer phoning home to tracking domains.

Immich Docker Compose Setup 2026: Self-Hosted Photo Backup for Homelabs

2026-06-05T00:33:00+07:00

Reading time: ~15 minutes
Audience: Users leaving Google Photos due to storage limits or privacy concerns
Last tested: Immich v1.131, PostgreSQL 16, Redis 7.4, June 2026

What Is Immich?

Overview

Immich is an open-source, self-hosted photo and video backup solution designed as a direct alternative to Google Photos, iCloud, and Amazon Photos. It offers automatic mobile uploads, AI-powered face recognition, duplicate detection, map-based browsing, and shared albums — all running on your own server.

Unlike Nextcloud’s basic photo viewer, Immich is purpose-built for large media libraries (100,000+ photos) with fast scrolling, instant search, and RAW file support.

Key Benefits

Feature	Immich	Google Photos	Nextcloud Photos
Cost	Free (your hardware)	$2–20/month	Free (your hardware)
AI face recognition	✅ On-device or server	✅ Cloud	❌
Auto-upload mobile	✅ iOS & Android	✅	Limited
RAW / HEIC support	✅	✅	Basic
Map timeline	✅	✅	❌
Duplicate detection	✅	❌	❌
Facial recognition privacy	Local only	Cloud processed	N/A

Prerequisites

Hardware Requirements

Library Size	RAM	CPU	Storage	GPU (Optional)
< 10,000 photos	4 GB	2 cores	100 GB SSD	Not needed
10,000–50,000	8 GB	4 cores	500 GB SSD	Intel UHD / NVIDIA for AI
50,000–200,000	16 GB	6 cores	2 TB SSD	Recommended
200,000+	32 GB	8+ cores	4 TB NVMe	Strongly recommended

RAM is the critical bottleneck. PostgreSQL with pgvecto.rs (Immich’s vector search extension) consumes significant memory during initial face recognition scans.

Software Requirements

Docker Engine 24.0+ and Docker Compose plugin
A Linux host with a static IP
(Optional) Reverse proxy for HTTPS
Mobile device with the Immich app (iOS or Android)

Step 1: Create the Docker Compose Stack

Objective

Write a production-ready Compose file with all required Immich services.

Step-by-Step Instructions

Create a project directory:

mkdir -p ~/immich && cd ~/immich

Create .env:

cat > .env << 'EOF'
# Database
DB_PASSWORD=change...hmod 600 .env

Create docker-compose.yml:

version: "3.8"

services:
  immich-server:
    container_name: immich_server
    image: ghcr.io/immich-app/immich-server:release
    restart: unless-stopped
    ports:
      - 2283:2283

      retries: 5
      start_period: 30s

volumes:
  pgdata:
  model-cache:
  ts-data:

Start the stack:

docker compose up -d

Verify all containers are healthy:

docker compose ps

Step 2: Initial Configuration

Objective

Complete the web setup and create your admin account.

Step-by-Step Instructions

Open your browser:

http://your-server-ip:2283

Click “Getting Started”.
Create the administrator account:
Email, password, name
Log in and explore the web UI.

Key settings to configure first:

Administration → Settings → Storage Template: Define how uploaded files are organized. Default is YYYY/MM/YYYY-MM-DD/filename.
Administration → Settings → External Libraries (Optional): If you have an existing photo collection on disk, mount it read-only and add it as an external library. Immich will index it without moving files.
Administration → Settings → Machine Learning: Enable Face Recognition, Smart Search, and Duplicate Detection.

Step 3: Mobile Auto-Upload Setup

Objective

Configure the Immich mobile app to back up photos automatically.

Step-by-Step Instructions

iOS: 1. Install Immich from the App Store. 2. Enter server URL: http://your-server-ip:2283 (or HTTPS domain) 3. Log in with your credentials. 4. Tap Profile (bottom right) → Backup 5. Enable: - Backup - Background backup - Wi-Fi only (recommended to save mobile data) - Albums to backup: select Camera Roll or all albums

Android: 1. Install Immich from F-Droid or Play Store. 2. Log in to your server. 3. Tap Albums → Backup 4. Enable backup and select albums. 5. For reliable background sync, disable battery optimization for the Immich app in Android settings.

Pro Tip: The first backup of 10,000+ photos can take days over Wi-Fi. Leave the app open and plugged in overnight for the initial sync.

Step 4: Reverse Proxy and HTTPS

Objective

Secure remote access with a reverse proxy.

Step-by-Step Instructions

NGINX Proxy Manager configuration:

Field	Value
Domain Names	`photos.yourdomain.com`
Scheme	`http`
Forward Hostname / IP	`immich_server` (if on same Docker network) or host IP
Forward Port	`2283`
Websockets Support	✅ Enabled
Block Common Exploits	✅ Enabled

Custom NGINX snippet for large uploads:

Immich uploads large video files. Increase the body size limit:

client_max_body_size 50G;
proxy_read_timeout 600s;
proxy_send_timeout 600s;
proxy_request_buffering off;
proxy_buffering off;

In NGINX Proxy Manager, add this to the Advanced tab of the Proxy Host.

Step 5: Running Face Recognition and Smart Search

Objective

Trigger the initial AI scan of your uploaded photos.

Step-by-Step Instructions

After uploading photos, go to Administration → Jobs.
Click the Run button next to each job:
Thumbnail Generation (creates preview images)
Metadata Extraction (reads EXIF, GPS)
Smart Search (AI-powered semantic search)
Face Detection (finds faces in photos)
Face Recognition (groups faces into people)
Duplicate Detection (finds similar images)
Monitor progress in the same panel. A library of 10,000 photos takes 2–4 hours on a 4-core CPU, or 30 minutes with GPU acceleration.

To enable GPU for machine learning:

Uncomment the deploy block in immich-machine-learning service.
Install NVIDIA Container Toolkit (see Jellyfin guide).
Restart the stack:

docker compose down
docker compose up -d

Pro Tips

Tip 1: Use External Libraries for Existing Collections

If you have 500 GB of existing photos on a NAS, do not re-upload them. Mount the NAS folder read-only and add it as an external library in Immich. Run the metadata and thumbnail jobs to index them.

Tip 2: Set Up Backup to a Second Location

Immich stores originals in the UPLOAD_LOCATION. Back this up alongside the PostgreSQL database:

docker exec immich_postgres pg_dump -U immich immich > immich-backup_$(date +%Y%m%d).sql
rsync -avP ${UPLOAD_LOCATION}/ /backup/immich-uploads/

Tip 3: Shared Albums for Family

Create user accounts for family members under Administration → Users. Each user gets their own private library. Create shared albums and invite others to view or contribute.

Tip 4: Handle HEIC Efficiently

iPhones shoot HEIC by default. Immich stores the original HEIC and generates a JPEG thumbnail. This saves ~40% storage compared to storing JPEG originals. Do not convert HEIC to JPEG before uploading.

Troubleshooting Common Issues

“Failed to connect to server” on Mobile App

Ensure the server URL includes the protocol: http:// or https://
If using a reverse proxy, verify Websockets are enabled
Check that immich_server container is healthy: docker compose ps

High RAM Usage During Scan

The immich_machine_learning container can spike to 4–8 GB RAM during initial face recognition. This is normal.
If the container is killed (OOM), increase Docker memory limits or add swap: bash sudo fallocate -l 8G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile

Duplicate Detection Not Finding Duplicates

Duplicate detection only runs on images with similar perceptual hashes. Slightly cropped or re-encoded images may not match.
Adjust the similarity threshold in Administration → Settings → Machine Learning.

Conclusion

Summary

You now have Immich running with PostgreSQL, Redis, Typesense, and optional GPU-accelerated machine learning. Your mobile devices can auto-upload, and you have AI-powered search, face recognition, and duplicate detection — all on hardware you control.

Migrate from ESXi to Proxmox: A Complete Homelab Migration Guide 2026

2026-06-05T00:33:00+07:00

Reading time: ~20 minutes
Audience: VMware ESXi homelab users affected by Broadcom licensing changes
Prerequisites: Running ESXi 6.7+ or 7.0/8.0, and a fresh Proxmox VE 8.2 node

Why Migrate from ESXi to Proxmox?

The Broadcom Situation

In late 2023, Broadcom acquired VMware and discontinued the free ESXi hypervisor (vSphere Hypervisor). As of 2024–2026, new ESXi downloads require a paid VMware Cloud Foundation (VCF) subscription, with per-core pricing that makes homelab use economically unreasonable. Existing free ESXi installations lost update access and are increasingly insecure.

Why Proxmox Is the Natural Replacement

Factor	ESXi (Pre-2024)	Proxmox VE 8.2
License cost	Free (discontinued)	Free, fully functional
Feature limits	RAM capped at 8 vCPUs	None
APIs	Locked vSphere APIs	Full REST API + CLI
Backup	Requires Veeam or paid VDP	Built-in vzdump
Storage	VMFS only	ZFS, LVM, Ceph, NFS, iSCSI
Community	Shrinking due to licensing	Growing rapidly

Prerequisites

Hardware Requirements

Resource	Minimum	Recommended
Proxmox host CPU	64-bit with VT-x	Same or better than ESXi host
Proxmox host RAM	4 GB	Match ESXi host RAM
Storage	128 GB SSD	Equal or greater than total VM disk usage
Network	1 GbE	1 GbE shared subnet for migration

Software Requirements

Access to ESXi Host Client (web UI) or vCenter
A fresh Proxmox VE 8.2 installation with available storage
SSH/SCP access between ESXi and Proxmox (or a shared NFS datastore)
Adequate free space on Proxmox for imported disks (thin-provisioned VMDKs expand to full size during import)

Step 1: Export VMs from ESXi as OVA/OVF

Objective

Create portable VM packages from ESXi that Proxmox can import.

Step-by-Step Instructions

Log in to the ESXi Host Client (https://esxi-ip).
Shut down the VM you want to migrate cleanly.
Right-click the VM → Export.
ESXi will generate two files:
.ovf — VM configuration (CPU, RAM, network, disk mappings)
.vmdk — Virtual disk image
Download both files to your local computer or an intermediate storage server.

Important: If the export is grayed out, power off the VM completely (not just a guest shutdown). Some ESXi versions require the VM to be fully stopped before export.

Alternative: SCP from ESXi datastore directly

If the web export fails or the VM is too large for browser download:

# From your Proxmox node (or any Linux machine)
scp root@esxi-ip:/vmfs/volumes/datastore1/vm-name/vm-name.vmdk /tmp/
scp root@esxi-ip:/vmfs/volumes/datastore1/vm-name/vm-name.ovf /tmp/

ESXi root password is required.

Step 2: Transfer Files to Proxmox

Objective

Move the exported VM files to the Proxmox node.

Step-by-Step Instructions

Option A: Direct SCP to Proxmox

scp /local/path/*.vmdk root@proxmox-ip:/var/lib/vz/dump/
scp /local/path/*.ovf root@proxmox-ip:/var/lib/vz/dump/

Option B: Shared NFS/SMB datastore

Mount a temporary NFS share on both ESXi and Proxmox:

# On Proxmox
mkdir -p /mnt/migration
mount -t nfs nas-ip:/export/migration /mnt/migration

Option C: USB external drive

For air-gapped networks, copy VMDKs to an external USB drive, attach it to the Proxmox host, and mount it.

Step 3: Import the VM into Proxmox

Objective

Convert the ESXi virtual disk and register it as a Proxmox VM.

Step-by-Step Instructions

SSH into your Proxmox node as root.
Create a target VM shell without disks (we will attach the imported VMDK):

qm create 9000 --name migrated-vm --memory 4096 --cores 2 --net0 virtio,bridge=vmbr0

Replace 9000 with an unused VM ID, and adjust RAM/cores to match the original VM.

Import the VMDK into Proxmox storage:

qm importdisk 9000 /var/lib/vz/dump/vm-name.vmdk local-lvm --format qcow2

If you are using ZFS or another storage:

qm importdisk 9000 /var/lib/vz/dump/vm-name.vmdk zfs-tank --format raw

Attach the imported disk to the VM:

qm set 9000 --scsi0 local-lvm:vm-9000-disk-1

Add a CD-ROM drive (optional, for driver installation):

qm set 9000 --ide2 local:iso/virtio-win.iso,media=cdrom

Set the boot disk:

qm set 9000 --boot order=scsi0

In the Proxmox web UI, inspect the VM under Hardware:
Ensure the disk shows as scsi0
Verify network adapter is virtio on vmbr0
Remove any IDE disk references if they were auto-created

Step 4: Post-Migration Configuration

Objective

Fix network drivers, install QEMU guest agent, and optimize for KVM.

Step-by-Step Instructions

For Windows VMs:

Start the VM and open the console.
Windows will likely detect new hardware (the virtual NIC changed from Intel E1000e to VirtIO).
Mount the VirtIO driver ISO:
In Proxmox UI: Hardware → CD/DVD Drive → Choose virtio-win.iso
Inside Windows, open Device Manager and update the Ethernet Controller driver by pointing it to the mounted ISO.
Install the QEMU guest agent for clean shutdowns and IP reporting:
Mount virtio-win.iso, navigate to guest-agent/, run qemu-ga-x64.msi

For Linux VMs:

Start the VM and open the console.
Linux usually detects VirtIO NICs automatically.
Install the QEMU guest agent:

sudo apt update && sudo apt install qemu-guest-agent   # Debian/Ubuntu
sudo yum install qemu-guest-agent                       # RHEL/CentOS
sudo systemctl enable --now qemu-guest-agent

Update initramfs if you switched disk controller types:

sudo update-initramfs -u   # Debian/Ubuntu
sudo dracut -f              # RHEL/Fedora

For all VMs:

Remove the CD-ROM after driver installation: bash qm set 9000 --delete ide2
Adjust memory ballooning if desired: bash qm set 9000 --balloon 2048
Enable Discard (TRIM) if the underlying storage is SSD: In the UI, go to Hardware → Hard Disk → Edit → Check “Discard”.

Step 5: Bulk Migration with `qm import` Scripting

Objective

Automate migration when you have many VMs.

Step-by-Step Instructions

For 5+ VMs, manual clicking becomes tedious. Use a shell loop:

#!/bin/bash
# migrate.sh — run on Proxmox as root

VM_LIST="vm1 vm2 vm3 vm4 vm5"
DATASTORE="local-lvm"
IMPORT_DIR="/var/lib/vz/dump"
START_ID=9000

for VM_NAME in $VM_LIST; do
  VMID=$((START_ID++))
  echo "Importing $VM_NAME as VMID $VMID..."

  qm create $VMID --name $VM_NAME --memory 4096 --cores 2 --net0 virtio,bridge=vmbr0
  qm importdisk $VMID $IMPORT_DIR/${VM_NAME}.vmdk $DATASTORE --format qcow2
  qm set $VMID --scsi0 ${DATASTORE}:vm-${VMID}-disk-1 --boot order=scsi0
  echo "Done: $VM_NAME"
done

Make executable and run:

chmod +x migrate.sh
./migrate.sh

Pro Tips

Tip 1: Convert Thick to Thin During Import

ESXi often uses thick-provisioned VMDKs. Proxmox’s qcow2 format is thin-provisioned by default, saving significant space. Always specify --format qcow2 unless you need raw performance.

Tip 2: Snapshot Before Migration

On ESXi, take a snapshot before powering off. If the migration fails, you can revert and retry without losing the running state.

Tip 3: Network MAC Address Preservation

If your VM has DHCP reservations or firewall rules tied to its MAC address, preserve it during migration:

qm set 9000 --net0 virtio=AA:BB:CC:DD:EE:FF,bridge=vmbr0

Tip 4: Test One VM Before Bulk Operations

Migrate your least critical VM first. Verify it boots, network works, and applications function before committing time to the rest.

Troubleshooting Common Issues

“No bootable device” After Import

Ensure the boot order includes scsi0 or virtio0: bash qm set 9000 --boot order=scsi0
Check that the imported disk is attached and not showing as “Unused” in the Hardware tab.

Blue Screen (INACCESSIBLE_BOOT_DEVICE) on Windows

The disk controller changed from VMware LSI Logic to VirtIO/SCSI. Before exporting from ESXi, install the VirtIO drivers inside Windows, or change the Proxmox disk controller to IDE temporarily, boot Windows, install drivers, then switch to SCSI.

Slow Import Speed

VMDK to QCOW2 conversion is CPU-intensive. On low-power hosts (N100), large disks can take hours. Consider: - Using screen or tmux so SSH disconnects do not abort the import - Scheduling bulk imports overnight

Network Not Connecting

Linux VMs may have network interface names changed (ens160 → ens18). Update /etc/netplan/ or /etc/network/interfaces accordingly.

Conclusion

Summary

You have exported VMs from ESXi, transferred them to Proxmox, converted VMDKs to QCOW2, attached them to new VM configurations, and fixed network drivers. The migration path is proven and does not require reinstalling operating systems or applications.

Nextcloud Docker Compose Setup 2026: Self-Hosted Cloud Storage Guide

2026-06-05T00:33:00+07:00

Reading time: ~16 minutes
Audience: Docker users ready to replace Google Drive / Dropbox / iCloud
Last tested: Nextcloud 30.0, MariaDB 11.4, Redis 7.4, June 2026

What Is Nextcloud?

Overview

Nextcloud is a self-hosted cloud storage and collaboration platform. It provides file sync, document editing (via Collabora or OnlyOffice), calendar/contacts sync (CalDAV/CardDAV), and a growing app ecosystem — all under your control, on your server, with no vendor lock-in or data mining.

For homelab users, Nextcloud is often the first “serious” self-hosted application. It replaces multiple SaaS subscriptions and gives you terabytes of storage without monthly fees.

Key Benefits

Feature	Nextcloud Self-Hosted	Google Drive / Dropbox
Storage cost	One-time hardware	$10–30/month for 2 TB+
Data privacy	You own the encryption keys	Provider can scan files
Custom domain	Yes	Business plans only
Apps / integrations	200+ community apps	Limited to vendor choices
Max file size	Limited only by disk/ZFS	750 GB upload limit
Offline sync	Desktop, Android, iOS	Desktop, Android, iOS

Prerequisites

Hardware Requirements

Users	RAM	CPU	Storage	Notes
1–2 personal	2 GB	2 cores	100 GB SSD	Raspberry Pi 5 or N100 viable
3–5 family	4 GB	4 cores	500 GB SSD + HDD backup	Recommended for most homelabs
10+ small team	8 GB	4 cores	1 TB NVMe + backup	Redis and database on same host

Software Requirements

Docker Engine 24.0+ and Docker Compose plugin
A Linux host with a static IP or local DNS name
(Optional) A reverse proxy for HTTPS (NGINX Proxy Manager, Traefik, or Caddy)

Step 1: Create the Docker Compose Stack

Objective

Write a production-grade docker-compose.yml with MariaDB, Redis, and Nextcloud.

Step-by-Step Instructions

Create a project directory:

mkdir -p ~/nextcloud && cd ~/nextcloud

Create .env for secrets:

cat > .env << 'EOF'
MYSQL_ROOT_PASSWORD=change-this-root-password-now
MYSQL_PASSWORD=change-this-db-password-now
NEXTCLOUD_ADMIN_USER=admin
NEXTCLOUD_ADMIN_PASSWORD=change-this-admin-password-now
NEXTCLOUD_TRUSTED_DOMAINS=nextcloud.yourdomain.com
EOF
chmod 600 .env

Create docker-compose.yml:

version: "3.8"

services:
  db:
    image: mariadb:11.4
    container_name: nextcloud-db
    restart: unless-stopped
    command: --transaction-isolation=READ-COMMITTED --log-bin=binlog --binlog-format=ROW
    volumes:
      - db-data:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
      - MYSQL_PASSWORD=${MYSQL_PASSWORD}
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
    healthcheck:
      test: ["CMD", "mariadb-admin", "ping", "-u", "root", "-p${MYSQL_ROOT_PASSWORD}"]
      interval: 10s
      timeout: 5s
      retries: 5

  redis:
    image: redis:7.4-alpine
    container_name: nextcloud-redis
    restart: unless-stopped
    volumes:
      - redis-data:/data
    command: redis-server --appendonly yes --maxmemory 256mb --maxmemory-policy allkeys-lru

    volumes:
      - nextcloud-data:/var/www/html
    environment:
      - MYSQL_PASSWORD=${MYSQL_PASSWORD}
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_HOST=db
      - REDIS_HOST=redis
      - NEXTCLOUD_ADMIN_USER=${NEXTCLOUD_ADMIN_USER}
      - NEXTCLOUD_ADMIN_PASSWORD=${NEXTCLOUD_ADMIN_PASSWORD}

      - OVERWRITEPROTOCOL=https
    depends_on:
      db:
        condition: service_healthy
      redis:
        condition: service_started
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:80/status.php"]
      interval: 30s
      timeout: 10s
      retries: 3

  cron:
    image: nextcloud:30-apache
    container_name: nextcloud-cron
    restart: unless-stopped
    volumes:
      - nextcloud-data:/var/www/html:ro
    entrypoint: /cron.sh
    depends_on:
      - db
      - redis

volumes:
  db-data:
  redis-data:
  nextcloud-data:

Architecture Note: We use MariaDB instead of PostgreSQL because it is more forgiving for beginners and widely tested with Nextcloud. Redis acts as a file locking cache, dramatically improving performance for concurrent users.

Step 2: Deploy and Complete Web Setup

Objective

Start the stack and finish installation through the web UI.

Step-by-Step Instructions

Start the stack:

docker compose up -d

Watch logs to ensure the database initializes:

docker compose logs -f db

Wait for the “mariadbd: ready for connections” line, then press Ctrl+C.

Open your browser:

http://your-server-ip:8080

You should see the Nextcloud setup screen. Because we passed admin credentials via environment variables, it may auto-create the admin account and skip the wizard. If not:
Create an admin account
Database: MySQL/MariaDB
Database user: nextcloud
Database password: (from .env)
Database name: nextcloud
Database host: db
Click Install
After installation, log in and go to Administration settings → Overview. Address any warnings (HTTPS, memory cache, etc.).

Step 3: Configure Redis and Performance

Objective

Enable Redis for file locking and adjust PHP memory limits.

Step-by-Step Instructions

Enter the Nextcloud app container:

docker exec -u www-data -it nextcloud-app bash

Configure Redis in Nextcloud:

php occ config:system:set redis host --value=redis
php occ config:system:set redis port --value=6379
php occ config:system:set memcache.locking --value=\\OC\\Memcache\\Redis
php occ config:system:set memcache.local --value=\\OC\\Memcache\\APCu

Increase PHP memory limit:

php occ config:system:set memory_limit --value=1024M

Set background jobs to use cron (already running in our cron service):

php occ background:cron

Exit the container:

exit

Restart the app container to apply:

docker compose restart app

Step 4: Reverse Proxy and HTTPS

Objective

Secure Nextcloud with HTTPS via NGINX Proxy Manager.

Step-by-Step Instructions

If you already have NGINX Proxy Manager running, add a Proxy Host:

Field	Value
Domain Names	`nextcloud.yourdomain.com`
Scheme	`http`
Forward Hostname / IP	`nextcloud-app`
Forward Port	`80`
Block Common Exploits	✅ Enabled
Websockets Support	✅ Enabled

Important Nextcloud config for reverse proxy:

Enter the app container and run:

php occ config:system:set trusted_proxies 0 --value=172.18.0.0/16
php occ config:system:set overwritehost --value=nextcloud.yourdomain.com
php occ config:system:set overwriteprotocol --value=https
php occ config:system:set overwrite.cli.url --value=https://nextcloud.yourdomain.com

Security Note: Do not expose port 8080 directly to the internet. Always use a reverse proxy with valid SSL certificates.

Step 5: Desktop and Mobile Sync Setup

Objective

Connect client apps to your self-hosted instance.

Step-by-Step Instructions

Desktop (Windows/macOS/Linux): 1. Download Nextcloud Desktop from nextcloud.com/install 2. Enter your server URL: https://nextcloud.yourdomain.com 3. Log in and choose folders to sync

Android / iOS: 1. Install Nextcloud from the Play Store / App Store 2. Enter server URL and credentials 3. Enable auto-upload for camera photos (a popular Immich alternative for simple sync)

CalDAV/CardDAV (Thunderbird, Apple Calendar, DAVx⁵): - URL: https://nextcloud.yourdomain.com/remote.php/dav - Use your Nextcloud username and app password (create one in Security → Devices & sessions)

Pro Tips

Tip 1: Enable Server-Side Encryption

If your data disk is not encrypted at rest, enable Nextcloud’s server-side encryption:

php occ encryption:enable
php occ encryption:encrypt-all

Note: This protects data at rest but adds CPU overhead. ZFS native encryption (zfs create -o encryption=on) is often a better alternative.

Tip 2: Offsite Backup with Restic

Back up your nextcloud-data and db-data volumes nightly:

docker exec nextcloud-db mariadb-dump -u root -p${MYSQL_ROOT_PASSWORD} nextcloud > nextcloud-sqlbkp_$(date +%Y%m%d).sql

Store the SQL dump and volume backup on a Hetzner Storage Box or local NAS.

Tip 3: Use Preview Generator

Generate thumbnails ahead of time to avoid CPU spikes when browsing photos:

php occ app:install previewgenerator
php occ preview:generate-all

Add to cron for periodic generation.

Tip 4: Limit Upload Size

The default upload limit is 2 GB. To raise it:

php occ config:system:set max_chunk_size --value=104857600

Also adjust the reverse proxy (client_max_body_size 10G; in NGINX).

Troubleshooting Common Issues

“Internal Server Error” on First Login

Check database connectivity: docker compose logs db
Ensure MariaDB finished initializing before Nextcloud started (our depends_on with condition: service_healthy handles this)
Verify .env passwords do not contain special characters that break YAML parsing (wrap in quotes if needed)

Slow File Listing

Ensure Redis is configured for file locking (see Step 3)
Enable PHP OPcache in the container (it is enabled by default in the official image)
Check that cron container is running: docker compose ps cron

“Trusted Domain” Error

Add your domain to NEXTCLOUD_TRUSTED_DOMAINS in .env, then:

docker compose down
docker compose up -d

Conclusion

Summary

You now have a production-grade Nextcloud deployment with MariaDB, Redis, cron jobs, and reverse proxy compatibility. It can serve a family or small team with file sync, calendars, contacts, and optional document editing.

Pi-hole + Unbound Docker Setup 2026: Recursive DNS for Privacy

2026-06-05T00:33:00+07:00

Reading time: ~13 minutes
Audience: Privacy-focused homelab users who want to stop leaking DNS queries to Cloudflare or Google
Last tested: Pi-hole FTL v6.0, Unbound 1.22, June 2026

Why Add Unbound to Pi-hole?

The Privacy Gap in Standard Pi-hole

By default, Pi-hole forwards filtered queries to upstream resolvers like Cloudflare (1.1.1.1), Quad9 (9.9.9.9), or Google (8.8.8.8). While these are fast and reliable, they see every domain you visit. Even with DNS-over-HTTPS (DoH), you are trusting a third party with your browsing metadata.

Unbound is a validating, recursive, caching DNS resolver. Instead of asking Google “what is example.com?”, Unbound asks the root DNS servers, then the .com TLD servers, then the authoritative nameservers for example.com. No third party ever sees your full query log.

Key Benefits

Feature	Pi-hole Only	Pi-hole + Unbound
Ad blocking	✅	✅
Tracker blocking	✅	✅
Recursive resolution	❌	✅
Third-party DNS logs	Yes (Cloudflare, etc.)	No
DNSSEC validation	Partial	Full end-to-end
Local caching	Minimal	Aggressive

Prerequisites

Hardware Requirements

Unbound requires slightly more RAM than forwarding to Cloudflare because it maintains a cache of DNS records:

Metric	Minimum	Recommended
RAM	512 MB	1 GB
CPU	1 core	2 cores (for initial root server queries)
Storage	8 GB	16 GB SSD (for Unbound cache and logs)

Software Requirements

Existing Pi-hole Docker deployment or willingness to deploy both together
Docker Engine and Docker Compose plugin
A static local IP for the DNS stack

Step 1: Deploy Unbound as a Separate Container

Objective

Create an Unbound container that Pi-hole will use as its sole upstream resolver.

Step-by-Step Instructions

If you already have Pi-hole running, create a new directory for Unbound:

mkdir -p ~/unbound && cd ~/unbound

If you are starting fresh, create a combined stack:

mkdir -p ~/pihole-unbound && cd ~/pihole-unbound

Create unbound.conf:

cat > unbound.conf << 'EOF'

    verbosity: 0
    num-threads: 2
    interface: 0.0.0.0

    private-address: fe80::/10

    # Root hints are built into the image; no extra config needed
    auto-trust-anchor-file: "/var/lib/unbound/root.key"
EOF

Create docker-compose.yml for the combined stack:

version: "3.8"

services:
  unbound:
    container_name: unbound
    image: mvance/unbound-rpi:latest  # Use mvance/unbound:latest for x86_64

        condition: service_healthy
    cap_add:
      - NET_ADMIN
    dns:
      - 127.0.0.1

Image selection: Use mvance/unbound:latest on Intel/AMD. Use mvance/unbound-rpi:latest on Raspberry Pi (ARM64). If those tags are unavailable, alpinelabs/unbound is a solid alternative.

Create directories and start:

mkdir -p etc-pihole etc-dnsmasq.d
docker compose up -d

Step 2: Verify Recursive Resolution

Objective

Confirm that Unbound is resolving and Pi-hole is using it.

Step-by-Step Instructions

Test Unbound directly:

dig @127.0.0.1 -p 5335 wordforge.example.com

You should see NOERROR and an IP address in the ANSWER SECTION.

Test DNSSEC validation (Unbound should return SERVFAIL for broken domains):

dig @127.0.0.1 -p 5335 dnssec-failed.org

Expected: status: SERVFAIL — this confirms DNSSEC validation is working.

Test through Pi-hole:

dig @127.0.0.1 -p 53 wordforge.example.com

Check Pi-hole dashboard → Settings → DNS.
Custom upstream should show unbound#5335
No other upstreams should be listed
Confirm no external resolvers are used:

docker logs pihole | grep "forwarded"

You should see to unbound#5335.

Step 3: Tune Unbound Performance

Objective

Optimize cache sizes and thread counts for your hardware.

Step-by-Step Instructions

For low-power hosts (Raspberry Pi, N100):

Keep the default config above. It is already tuned for modest hardware.

For dedicated servers with 4+ cores and 4+ GB RAM:

Increase cache sizes in unbound.conf:

num-threads: 4
rrset-cache-size: 256m
msg-cache-size: 128m
so-rcvbuf: 4m
so-sndbuf: 4m

Restart Unbound:

docker compose restart unbound

Monitor cache hit rate:

docker exec unbound unbound-control stats_noreset | grep cache

A hit rate above 70% is excellent for a home network.

Step 4: Maintain and Update

Objective

Keep both services updated without losing configuration.

Step-by-Step Instructions

Update both containers:

cd ~/pihole-unbound
docker compose pull
docker compose up -d

Clear Unbound cache if needed:

docker exec unbound unbound-control flush

Backup your configuration:

tar czf pihole-unbound-backup-$(date +%Y%m%d).tar.gz etc-pihole etc-dnsmasq.d unbound.conf docker-compose.yml .env

Pro Tips

Tip 1: Add DNS-over-TLS for External Queries

If you occasionally need to query an external resolver (e.g., for GeoCDN accuracy), configure Unbound to forward specific zones over TLS:

forward-zone:
    name: "."
    forward-addr: 1.1.1.1@853#cloudflare-dns.com
    forward-ssl-upstream: yes

This hybrid mode uses Unbound for recursion but encrypts the final hop.

Tip 2: Split-Horizon DNS for Homelab

Unbound can serve local records without Pi-hole’s involvement:

local-zone: "lan." static
local-data: "proxmox.lan. IN A 192.168.1.5"
local-data: "nas.lan. IN A 192.168.1.20"

Restart Unbound and query: dig @192.168.1.10 -p 5335 proxmox.lan

Tip 3: Reduce TTL for Faster Blocklist Updates

When you add a new blocklist to Pi-hole, old cached records may persist. Lower Unbound’s cache-min-ttl to 60 seconds temporarily, then raise it back to 300 after Gravity updates.

Tip 4: Run on a Separate VLAN

For network segmentation, place Pi-hole + Unbound on a dedicated management VLAN (e.g., VLAN 10). Ensure your router allows UDP/TCP 53 from all client VLANs to the DNS VLAN.

Troubleshooting Common Issues

“connection refused” on Port 5335

Unbound container may not be fully started. Check logs: bash docker compose logs unbound
Ensure no other service is using port 5335 on the host.

Slow Initial Resolution

Unbound must populate its cache from root servers. The first query to any domain is slower (~200–500 ms) than Cloudflare (~20 ms). Subsequent queries are cached and typically faster than external resolvers.
This is normal and improves dramatically after 24 hours of use.

“Server Failed” for All Queries

Check that auto-trust-anchor-file is generating correctly: bash docker exec unbound ls -la /var/lib/unbound/
If root.key is missing, generate it manually: bash docker exec unbound unbound-anchor -a /var/lib/unbound/root.key docker compose restart unbound

Conclusion

Summary

You now have a privacy-first DNS stack: Pi-hole filters ads and trackers, while Unbound performs recursive resolution without leaking your browsing history to upstream providers. Your network enjoys faster cached DNS, end-to-end DNSSEC validation, and complete query autonomy.

Portainer Setup Guide 2026: Visual Docker Management for Homelabs

2026-06-05T00:33:00+07:00

Reading time: ~10 minutes
Audience: Docker users who prefer GUIs over terminal commands
Last tested: Portainer CE 2.25, June 2026

What Is Portainer?

Overview

Portainer Community Edition (CE) is a lightweight web-based management interface for Docker, Docker Swarm, and Kubernetes. It translates every Docker operation — starting containers, inspecting logs, managing volumes, editing Compose files — into clickable buttons and forms.

For homelab users, Portainer eliminates the need to SSH into your server every time you want to check a container log or update an image. It also provides a built-in stack editor with Git integration, making it ideal for managing 10–50 self-hosted applications.

Key Benefits

Feature	Portainer	Docker CLI
Start/stop containers	One click	`docker start/stop`
View logs	Real-time web stream	`docker logs -f`
Edit Compose stacks	In-browser YAML editor + redeploy	Edit file + CLI commands
Browse container files	Web file manager	`docker exec -it ... bash`
Multi-host management	Single UI for multiple nodes	SSH to each host
App templates	50+ one-click app templates	Manual `docker compose up`

Portainer CE vs Portainer Business (BE)

Capability	CE (Free)	BE (Paid)
Container management	✅	✅
Stack editing	✅	✅
Multi-environment	1	Unlimited
RBAC / Teams	❌	✅
Registry management	✅	✅

For single-user homelabs, CE provides everything you need.

Prerequisites

Hardware Requirements

Component	Minimum	Recommended
CPU	Any x86_64 or ARM64	2 cores
RAM	512 MB for Portainer itself	2 GB total for host
Storage	10 MB for Portainer image	20 GB SSD for host
Network	Same subnet as your client	Static IP preferred

Software Requirements

Docker Engine 24.0+ with Docker Compose plugin
A Linux host (Ubuntu, Debian, Proxmox LXC, Raspberry Pi OS)
The host must have internet access to pull images

Step 1: Create the Portainer Data Volume

Objective

Prepare persistent storage so Portainer settings survive updates.

Step-by-Step Instructions

SSH into your Docker host.
Create a dedicated Docker volume:

docker volume create portainer_data

Verify it exists:

docker volume ls

Why a named volume? Portainer stores user accounts, endpoint configurations, and stack definitions in /data. A named volume persists this across image updates. Bind mounts work too, but named volumes are cleaner for single-file databases.

Step 2: Deploy Portainer via Docker Compose

Objective

Launch Portainer CE with a simple, maintainable Compose file.

Step-by-Step Instructions

Create a directory for Portainer:

mkdir -p ~/portainer && cd ~/portainer

Create docker-compose.yml:

version: "3.8"

services:
  portainer:
    image: portainer/portainer-ce:2.25-alpine
    container_name: portainer
    restart: unless-stopped
    security_opt:
      - no-new-privileges:true
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - portainer_data:/data
    ports:
      - "9000:9000"
      - "8000:8000"  # Only needed for Edge Agent setups

volumes:
  portainer_data:

Start the container:

docker compose up -d

Check that it is running:

docker compose ps
docker compose logs -f

You should see portainer in an Up state.

Security Note: Mounting /var/run/docker.sock gives Portainer full control over Docker on the host. This is necessary for its functionality but means you should not expose Portainer to the public internet without HTTPS + strong authentication.

Step 3: Initial Configuration and Connecting the Environment

Objective

Complete the first-run wizard and connect Portainer to your local Docker socket.

Step-by-Step Instructions

Open your browser and navigate to:

http://your-server-ip:9000

You will see the “Create the first administrator user” screen.
Username: Choose something memorable (e.g., admin)
Password: Use a strong, unique password (16+ characters)
Confirm password: Re-enter it
Click “Create user”.
On the “Environment Wizard” screen, select “Get Started”.
Choose “Docker” as the environment type, then “Start Wizard”.
Select “Docker environment” and click “Connect”.

Portainer will detect the local Docker socket and import all existing containers, volumes, networks, and images.

Step 4: Exploring the Portainer Interface

Objective

Learn the main sections and where to find critical functions.

Step-by-Step Instructions

Left sidebar navigation:

Menu Item	Purpose
Dashboard	Overview of running/stopped containers, CPU, RAM, and network usage
App Templates	One-click installers for common apps (NGINX, MySQL, WordPress, etc.)
Stacks	View and edit Docker Compose stacks
Containers	Start, stop, kill, pause, resume, inspect, view logs, access console
Images	Pull, build, remove, and inspect Docker images
Networks	Manage bridge, overlay, and custom networks
Volumes	Create, inspect, and delete named volumes
Events	Real-time Docker daemon event stream
Host	View disk usage, running processes, and system info

Key actions to try:

View logs: Click any container → Logs tab. Use the search box to filter.
Access console: Click any container → Console tab → Choose /bin/bash or /bin/sh → Connect.
Inspect a container: Click any container → Inspect tab to see the raw JSON Docker config.
Edit a running container: You cannot directly edit a running container’s config, but you can Duplicate/Edit to clone it with changes.

Step 5: Deploying a Stack from the Web Editor

Objective

Use Portainer’s built-in editor to deploy a multi-container application without touching the terminal.

Step-by-Step Instructions

In Portainer, click Stacks → Add stack.
Name the stack: whoami-demo
In the Web editor, paste:

version: "3.8"

services:
  whoami:
    image: traefik/whoami
    container_name: whoami-web
    ports:
      - "8080:80"
    restart: unless-stopped

Click Deploy the stack.
Navigate to Containers. You will see whoami-web running.
Visit http://your-server-ip:8080 to confirm it responds.

To update a stack: 1. Go to Stacks → whoami-demo → Editor. 2. Make changes (e.g., change the image tag). 3. Click Update the stack → Pull latest images.

Pro Tips

Tip 1: Use Portainer with a Reverse Proxy

Do not expose Portainer on port 9000 directly to the internet. Put it behind NGINX Proxy Manager or Traefik:

# In your reverse proxy stack
services:
  nginx-proxy-manager:
    image: jc21/nginx-proxy-manager:latest
    ports:
      - "80:80"
      - "443:443"
      - "81:81"
    # Add a Proxy Host in the NPM UI:
    # Domain: portainer.yourdomain.com
    # Forward Host: portainer
    # Forward Port: 9000

Tip 2: Back Up Portainer Data

The entire Portainer state lives in the portainer_data volume. Back it up with:

docker run --rm -v portainer_data:/data -v $(pwd):/backup alpine \
  tar czf /backup/portainer-backup.tar.gz -C /data .

Tip 3: Enable Dark Mode

Go to My account → Theme → Dark. Portainer’s light theme is blinding at 2 AM during a homelab debug session.

Tip 4: Use Git Repositories for Stacks

Instead of editing in the browser, connect Portainer to a Git repo: 1. Stacks → Add stack → Repository 2. Enter your Git URL, branch, and Compose file path 3. Enable Authentication if the repo is private 4. Enable Automatic updates to poll for changes every X minutes

This turns Portainer into a lightweight GitOps controller for your homelab.

Troubleshooting Common Issues

“Cannot connect to the Docker daemon”

Verify the Docker service is running: sudo systemctl status docker
Ensure /var/run/docker.sock exists on the host
If running in LXC, ensure the container is privileged or has nesting=1 and keyctl=1

Forgotten Admin Password

If you locked yourself out, reset via CLI:

docker stop portainer
docker run --rm -v portainer_data:/data portainer/portainer-ce:2.25-alpine \
  --admin-reset-password
# Follow prompts, then restart Portainer
docker start portainer

High Memory Usage

Portainer itself uses ~50–100 MB RAM. If memory spikes, it is likely due to a large number of images or containers. Prune unused images in Images → Prune.

Conclusion

Summary

You now have Portainer CE running as a web UI for your Docker host. You can inspect logs, manage containers, deploy stacks from a browser, and even connect Git repositories for automatic deployments.

Next Steps

Deploy Nextcloud via Portainer Stack Editor
Compare Portainer vs Cockpit for full-system management
Set up NGINX Proxy Manager for clean local domains
Monitor your containers with Grafana and Prometheus

Affiliate Opportunities

Mini PCs: Compact Docker hosts (Intel N100, Beelink SER5)
Monitors: A small touchscreen display mounted near your server rack for quick Portainer checks
UPS: Keep Portainer accessible during power flickers

Proxmox Beginner Guide 2026: From Zero to Your First VM

2026-06-05T00:33:00+07:00

Reading time: ~18 minutes
Audience: Homelab beginners migrating from bare-metal or cloud VMs
Last tested: Proxmox VE 8.2, June 2026

What Is Proxmox VE?

Overview

If you are new to homelab and want to run multiple operating systems on one machine, Proxmox Virtual Environment (VE) is the best place to start in 2026. It is free, open-source, and built on Debian Linux. Unlike VMware ESXi — which killed its free tier after the Broadcom acquisition — Proxmox gives you full features without a license key.

Proxmox Virtual Environment (VE) is an open-source Type-1 hypervisor based on Debian Linux. It combines two virtualization technologies in a single web interface: KVM for full virtual machines (VMs) and LXC for lightweight Linux containers. Unlike VMware ESXi or Microsoft Hyper-V, Proxmox is completely free for homelab use without artificial feature limits, and it includes enterprise-grade features like software-defined storage (Ceph, ZFS), live migration, and backup scheduling out of the box.

Key Benefits for Homelab Users

Feature	Proxmox VE	Typical Consumer NAS / Cloud
Cost	Free (subscription optional)	$100–500/year or hardware lock-in
Virtualization	KVM + LXC	Often none or Docker-only
Storage	ZFS, Ceph, LVM, NFS, iSCSI	Proprietary RAID
Backup	Built-in vzdump + scheduler	Manual or paid add-on
Hardware choice	Any x86_64 server/PC	Vendor-locked
Learning curve	Moderate	Low, but less capable

Prerequisites

Minimum Hardware Requirements

Component	Minimum	Recommended for 3+ VMs	Notes
CPU	64-bit dual-core	4c/8t Intel or AMD, ECC optional	More cores = more concurrent VMs
RAM	4 GB	16–32 GB DDR4/DDR5	Plan 2–4 GB per VM + 2 GB for host
Storage	32 GB SSD	256 GB NVMe + HDD for backups	ZFS loves fast drives; avoid SMR HDDs
Network	1 GbE	2× 1 GbE or 10 GbE	Wi-Fi is unsupported for the host
USB port	1 (for installer)	1

Real-world beginner builds in 2026:

Budget: Old Dell OptiPlex or HP EliteDesk (6th–8th gen Intel), 16 GB RAM, 256 GB SATA SSD
Sweet spot: Intel N100 or N305 mini PC, 32 GB DDR5, 512 GB NVMe
Enthusiast: Used Dell PowerEdge R620/R720 or HP ProLiant DL380p, dual Xeon, 64–128 GB ECC RAM

The Intel N100 has become the most popular entry point in 2026. It draws under 15W at idle, costs around $150–$200 for a barebones unit, and handles 3–4 lightweight VMs without issue. Models from Beelink, GMKtec, and Minisforum are well-tested in the community.

BIOS/UEFI Settings to Check Before Installing

Enable Intel VT-x / AMD-V (virtualization extensions)
Enable Intel VT-d / AMD-Vi (IOMMU) if you plan GPU passthrough later
Disable Secure Boot — Proxmox does not ship with a signed bootloader
Set boot order to USB first

Software Requirements

Proxmox VE 8.2 ISO (download)
BalenaEtcher, Rufus, or dd to write the ISO to a USB drive (8 GB+)
A second computer or smartphone to access the web UI

Step 1: Download and Create Bootable Media

Objective

Prepare a bootable USB drive with the Proxmox VE installer.

Step-by-Step Instructions

Download the latest Proxmox VE 8.2 ISO from the official website. Verify the SHA256 checksum if you are security-conscious.
Insert your USB drive. All data on it will be erased.
Flash the ISO using your preferred tool:

Linux/macOS:

sudo dd if=proxmox-ve_8.2-1.iso of=/dev/sdX bs=4M status=progress conv=fsync

Replace /dev/sdX with your actual USB device (check with lsblk).

Windows: Use Rufus in “DD mode” or BalenaEtcher.

Safely eject the USB and insert it into your target server.

Step 2: Install Proxmox on Your Hardware

Objective

Run the graphical installer and configure networking.

Step-by-Step Instructions

Power on the server and boot from the USB drive.
Select “Install Proxmox VE (Graphical)” from the GRUB menu.
Accept the EULA.
Choose your target disk. If you have multiple disks:
Install Proxmox on your smallest/fastest SSD.
Leave larger HDDs untouched for now; we will add them as storage later.
Select your country, timezone, and keyboard layout.
Set a strong root password and enter an email address for system notifications.
Network configuration — this is critical:
Management interface: Select your primary NIC (e.g., enp3s0 or eth0).
Hostname: Use a fully qualified domain name (FQDN) like pve.lan or pve.home.arpa.
IP address: Assign a static IP outside your router’s DHCP pool, e.g., 192.168.1.10/24.
Gateway: Your router’s IP (e.g., 192.168.1.1).
DNS: 1.1.1.1 or your router’s IP.
Review the summary and click Install. The system will reboot automatically.

Pro Tip: Write down the IP address you assigned. The web UI will be accessible at https://192.168.1.10:8006.

Step 3: First Login and Web UI Overview

Objective

Access the web interface and understand the main sections.

Step-by-Step Instructions

On another computer, open a browser and navigate to: https://<your-proxmox-ip>:8006 You will see a self-signed certificate warning. Click Advanced → Proceed (or add an exception).
Log in with Username: root and the password you set during installation.
Dismiss the subscription nag (bottom-right “X”). Proxmox works fully without a paid subscription; the nag is cosmetic.

Web UI Layout

Panel	Purpose
Left sidebar	Resource tree: Datacenter → Node → VMs/Containers/Storage
Center pane	Details, graphs, and configuration for the selected item
Top buttons	Create VM, Create CT, Start/Stop/Console actions
Right sidebar	Contextual options (Hardware, Options, Backup, etc.)

Step 4: Configure Storage

Objective

Add your data disks to Proxmox so VMs can use them.

Step-by-Step Instructions

In the left sidebar, click Datacenter → Storage.
Click Add → Directory to add a simple mount point, or Add → ZFS if you want redundancy.

For a single data disk (simplest):

# SSH into Proxmox as root
lsblk  # Identify your data disk (e.g., /dev/sdb)
fdisk /dev/sdb  # Create a single Linux partition (type 83)
mkfs.ext4 /dev/sdb1
mkdir /mnt/data
mount /dev/sdb1 /mnt/data
echo '/dev/sdb1 /mnt/data ext4 defaults 0 2' >> /etc/fstab

In the web UI, click Datacenter → Storage → Add → Directory:
ID: data-disk
Directory: /mnt/data
Content: Disk image, Container
Click Add.

For ZFS (recommended if you have 2+ identical disks):

zpool create tank mirror /dev/sdb /dev/sdc

Then add tank as a ZFS storage in the UI.

Step 5: Create Your First Virtual Machine

Objective

Deploy an Ubuntu Server VM with best-practice settings.

Step-by-Step Instructions

Download the Ubuntu Server 24.04 LTS ISO to your local computer.
In Proxmox, click local (pve) → ISO Images → Upload and select the ISO.
Click the Create VM button (top right).
General: Give it a name like ubuntu-test. Leave VM ID as auto-assigned.
OS: Select Use CD/DVD disc image file (iso) and pick your uploaded ISO.
System: Leave defaults. If installing Windows, check Add TPM and set version to 2.0, and enable Secure Boot.
Disks:
Bus/Device: SCSI
Storage: data-disk (or local-lvm if you only have one disk)
Disk size: 20 GB
Check Discard (enables TRIM for SSDs)
CPU:
Sockets: 1
Cores: 2
Type: host (for best performance on single-node setups)
Memory: 2048 MiB (2 GB). Leave Ballooning unchecked for now.
Network:
- Bridge: vmbr0 (default)
- Model: VirtIO (best performance)
- Leave VLAN blank unless you have configured VLANs
Confirm and finish.
Start the VM, open the Console, and install Ubuntu as you would on physical hardware.

Pro Tip: After installing the OS, go to Hardware → CD/DVD Drive → Remove so the VM boots from disk, not ISO.

Pro Tips

Tip 1: Install QEMU Guest Agent

The QEMU guest agent improves shutdown behavior and enables IP reporting in the Proxmox UI.

sudo apt update && sudo apt install qemu-guest-agent
sudo systemctl enable --now qemu-guest-agent

Tip 2: Use Templates, Not Clones from ISOs

After setting up a clean VM, right-click it and select Convert to Template. Future VMs can be cloned from this template in seconds instead of reinstalling from ISO.

Tip 3: Back Up Before Major Changes

Click a VM → Backup → Backup Now. The default vzdump format compresses well and can be restored to any Proxmox node.

Tip 4: Enable Dark Mode

Go to User → My Settings → UI Language and switch to the dark theme. Your eyes will thank you.

Troubleshooting Common Issues

Cannot Access Web UI

Verify the IP address with ip a from the Proxmox terminal (Alt+F2 or SSH).
Ensure your client PC is on the same subnet.
Try https://<ip>:8006 with both HTTP and HTTPS explicitly.

VM Boots to Black Screen

Change the display from Default to VirtIO-GPU or VNC in Hardware settings.
Ensure the ISO is mounted and boot order has CD-ROM first for initial install.

Slow Disk Performance

Ensure you selected VirtIO SCSI or SCSI with Discard enabled.
Avoid IDE emulation — it is emulated in software and significantly slower.

Conclusion

Summary

You now have a working Proxmox VE 8.2 node with configured storage and a running Ubuntu VM. Proxmox scales from a single Intel N100 mini-PC to a multi-node Ceph cluster. The same interface you used today will manage 50 VMs or 50 nodes tomorrow.

Next Steps

Learn Docker Compose on Proxmox to run modern self-hosted apps
Set up Portainer for a visual Docker management layer
Compare Proxmox vs ESXi if you are migrating from VMware
Explore LXC containers — lighter than VMs for Linux-only workloads

Affiliate Opportunities

Self-Hosted Media Server Setup 2026: Jellyfin Docker Compose Guide

2026-06-05T00:33:00+07:00

Reading time: ~14 minutes
Audience: Media enthusiasts leaving Plex or Emby due to policy changes or subscription fatigue
Last tested: Jellyfin 10.10, June 2026

What Is Jellyfin?

Overview

Jellyfin is a free, open-source media server forked from Emby before it went closed-source. It organizes your movies, TV shows, music, and photos into a Netflix-like interface, then streams them to browsers, mobile apps, smart TVs, and DLNA devices — all without calling home, collecting telemetry, or charging subscription fees.

Unlike Plex, Jellyfin does not require account creation, and your viewing habits are never sent to a third-party analytics platform.

Key Benefits

Feature	Jellyfin	Plex	Emby
Cost	100% free	Freemium (paid features)	Freemium
Open source	✅ (GPLv2)	❌	Partial
Phone home / telemetry	None	Yes	Yes
Hardware transcoding	Free	Paid (Plex Pass)	Paid (Premiere)
Live TV / DVR	Free	Paid	Paid
Plugins	30+ community	Curated store	Curated store

Prerequisites

Hardware Requirements

Use Case	CPU	RAM	Storage	GPU
Direct play only (no transcode)	Any 2-core	2 GB	1 TB+ HDD	None
2–3 concurrent 1080p transcodes	4-core modern	4 GB	1 TB SSD for metadata	Intel UHD / Iris Xe
4+ concurrent 4K HDR → 1080p	6-core	8 GB	256 GB SSD cache + NAS	Intel Arc, NVIDIA GTX 1650+

Transcoding Quick Reference

Direct Play: The client plays the file as-is. Zero CPU/GPU usage. Best quality.

Transcoding: The server re-encodes the video in real time for incompatible clients (old phones, bandwidth-limited remotes). This is where hardware acceleration matters.

Codec	Direct Play Support	Often Needs Transcode
H.264 (AVC)	Universal	Rare
H.265 (HEVC)	Modern devices	Older Roku, web browsers
AV1	2022+ devices	Almost everything else
4K HDR → 1080p SDR	Never direct	Always (tone mapping)

Step 1: Deploy Jellyfin with Docker Compose

Objective

Create a Compose file with proper volume mappings for media, config, and hardware device access.

Step-by-Step Instructions

Create a project directory:

mkdir -p ~/jellyfin/{config,cache,media} && cd ~/jellyfin

Set correct permissions (Jellyfin runs as UID/GID 1000:1000 by default):

chown -R 1000:1000 config cache

Create docker-compose.yml:

version: "3.8"

services:
  jellyfin:
    image: jellyfin/jellyfin:10.10
    container_name: jellyfin
    restart: unless-stopped
    user: 1000:1000
    group_add:
      - "105"  # Change to your host's render group ID for GPU access
    network_mode: host  # Simplifies DLNA and client discovery
    volumes:
      - ./config:/config
      - ./cache:/cache
      - /mnt/media:/media:ro  # Read-only access to your media library
    environment:
      - JELLYFIN_PublishedServerUrl=http://jellyfin.lan
    # Uncomment the appropriate device block for GPU transcoding:
    # Intel Quick Sync:
    # devices:
    #   - /dev/dri:/dev/dri
    # NVIDIA:
    # deploy:
    #   resources:
    #     reservations:
    #       devices:
    #         - driver: nvidia
    #           count: 1
    #           capabilities: [gpu]

Find your render group ID (for Intel/AMD GPU passthrough):

getent group render | cut -d: -f3

Replace 105 in group_add with your actual value.

Start Jellyfin:

docker compose up -d

Access the web UI:

http://your-server-ip:8096

Step 2: Initial Library Setup

Objective

Add media folders and let Jellyfin scan your collection.

Step-by-Step Instructions

On first launch, Jellyfin walks you through setup:
Preferred display language: Choose your language
Username / Password: Create the admin account
Add Media Library:
- Content type: Movies, TV Shows, Music, etc.
- Display name: e.g., “Movies”, “TV Shows”
- Folders: /media/movies, /media/tv, etc.
- Preferred language: English (or your language)
- Metadata downloaders: Enable TheMovieDB, TheTVDB, OMDB
- Image fetchers: Enable TheMovieDB, Screen Grabber
Click Next → Next → Finish.
Jellyfin will begin scanning. For 1,000 movies, this takes 15–30 minutes depending on internet speed and CPU.

Pro Tip: Name files accurately. Jellyfin matches using Movie Name (Year) and Series Name - SXXEYY patterns. Tools like Sonarr and Radarr automate naming.

Step 3: Enable Hardware Transcoding

Objective

Offload video transcoding from CPU to GPU for smooth 4K→1080p conversions.

Step-by-Step Instructions

For Intel Quick Sync (12th–14th Gen, N100–N305):

Ensure /dev/dri is passed through in docker-compose.yml:

    devices:
      - /dev/dri:/dev/dri

In Jellyfin web UI: Administration → Playback → Transcoding
Enable hardware decoding: ✅
Hardware acceleration: Intel QuickSync (QSV)
Enable hardware encoding: ✅
Allow decoding: Check all formats (H264, HEVC, VP9, AV1)
Click Save.
Test by playing a 4K file on a remote device and checking the dashboard for the orange ✅ “Transcoding” indicator. CPU usage should drop to <10%.

For NVIDIA GPUs:

Install the NVIDIA Container Toolkit on the host:

distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt update && sudo apt install -y nvidia-docker2
sudo systemctl restart docker

Use the deploy block in Compose (shown in Step 1).
In Jellyfin, select NVIDIA NVENC as the acceleration method.

Step 4: Remote Access and HTTPS

Objective

Stream securely from outside your home network.

Step-by-Step Instructions

Option A: Reverse Proxy (Recommended)

In Jellyfin: Administration → Networking: - Base URL: leave blank - Public HTTPS port: 443 - Known proxies: Add your reverse proxy IP or subnet

Option B: Tailscale / Zero Trust

Install Tailscale on your Jellyfin host and client devices. Access Jellyfin at http://jellyfin-host:8096 over the encrypted mesh network without opening firewall ports.

Option C: Direct Port Forward (Not Recommended)

Forward router port 8096 to your Jellyfin host. Only use this with Jellyfin’s built-in HTTPS and strong passwords.

Pro Tips

Tip 1: Use Sonarr + Radarr + Bazarr for Automation

Sonarr: TV show downloading and renaming
Radarr: Movie downloading and renaming
Bazarr: Subtitle downloading
Prowlarr: Indexer management

Run them all in a separate Docker Compose stack and point their root folders to /mnt/media.

Tip 2: Enable Tone Mapping for HDR Content

Without tone mapping, HDR movies look washed out on SDR screens: - Administration → Playback → Tone mapping: Enable - Tone mapping algorithm: BT.2390 (best quality) or Reinhard (lower GPU load) - Tone mapping mode: GPU if you have hardware acceleration

Tip 3: Cache Metadata on SSD

If your media lives on a slow NAS or HDD, keep Jellyfin’s config and cache on an SSD. Our Compose file already does this via ./config and ./cache bind mounts.

Tip 4: Limit Transcode Sessions

Prevent a single remote user from monopolizing your GPU: - Administration → Playback → Transcoding → Max transcode sessions: 2

Troubleshooting Common Issues

“No compatible streams” Error

The client cannot direct play the file and transcoding is failing.
Check that hardware acceleration is enabled and /dev/dri is visible inside the container: bash docker exec -it jellyfin ls -la /dev/dri
If empty, your group_add or devices block is incorrect.

Slow Library Scanning

Disable real-time monitoring if using network storage (NFS/SMB): Administration → Libraries → [Library] → Advanced → Enable real time monitoring: ❌
Schedule a nightly scan instead: Administration → Scheduled Tasks → Scan Media Library

Subtitles Not Showing

Ensure the subtitle file has the same base name as the video: Movie (2024).mkv → Movie (2024).en.srt
Or use Bazarr to fetch subtitles automatically.

Conclusion

Summary

You now have Jellyfin running in Docker with hardware transcoding, a properly organized media library, and secure remote access. It replaces Plex or Emby without subscription fees or telemetry.

Next Steps

Affiliate Opportunities

Storage: WD Red Plus or Seagate IronWolf NAS drives for media libraries

AdGuard Home Setup Guide: Network-Wide Ad Blocking in 2026

2026-06-05T00:00:00+07:00

Reading time: ~12 minutes Audience: Homelabbers wanting a modern, user-friendly DNS ad blocker

What Is AdGuard Home?

Overview

AdGuard Home is a network-wide DNS ad blocker that blocks ads, trackers, and adult content at the DNS level. It is similar to Pi-hole but offers a more modern web UI, better parental controls, native DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) support, and built-in DHCP server functionality.

Key Benefits

Benefit	Detail
Modern UI	Clean, responsive web interface with dark mode
Encrypted DNS	Native DoH and DoT support without extra containers
Parental controls	Block adult sites, enforce safe search, schedule internet access
Query log	Fast, filterable log with client identification
Statistics	Per-client stats, top queried domains, top blocked domains
Blocking modes	Default hosts, NXDOMAIN, Null IP, or custom IP
DNS rewrites	Local DNS records (split-horizon DNS)
Upstreams	Easy load balancing and fallback DNS resolvers

Prerequisites

Hardware Requirements

Any device running Docker or Linux (mini PC, Raspberry Pi, NAS, VM)
256MB RAM minimum (512MB recommended)
100MB storage for the binary + log space

Software Requirements

Docker Engine 24.x+ or a Debian 12/Ubuntu 24.04 host
Router access to change DNS settings
Port 3000 free (for initial setup) and port 53 (for DNS)

Knowledge Prerequisites

Basic Docker or Linux commands
Router admin panel access
DNS concepts

Step 1: Install AdGuard Home with Docker Compose

Objective

Deploy AdGuard Home as a persistent container with proper volumes and network settings.

Step-by-Step Instructions

Create the project directory:

mkdir -p ~/docker/adguardhome && cd ~/docker/adguardhome
mkdir -p workdir confdir

Create docker-compose.yml:

services:
  adguardhome:
    container_name: adguardhome
    image: adguard/adguardhome:latest
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "8080:80/tcp"
      - "8443:443/tcp"
      - "3000:3000/tcp"
    volumes:
      - ./workdir:/opt/adguardhome/work
      - ./confdir:/opt/adguardhome/conf
    restart: unless-stopped
    networks:
      - adguard-net

networks:
  adguard-net:
    driver: bridge

Deploy:

docker compose up -d

Complete the initial setup wizard:
Open http://your-server-ip:3000
Set admin username and a strong password
Choose interface and port (keep 0.0.0.0:53 for DNS, 80 for web UI)
Set upstream DNS resolvers (Cloudflare, Quad9, or custom)
Create filters and click “Open Dashboard”
After setup, the web UI moves to port 80:
Access at http://your-server-ip:8080

Step 2: Configure DNS and Upstream Resolvers

Objective

Set up reliable upstream DNS with encryption and fallback options.

Step-by-Step Instructions

Go to Settings → DNS settings
Upstream DNS servers:

# DNS-over-HTTPS (DoH)
https://dns.cloudflare.com/dns-query
https://dns.quad9.net/dns-query

# DNS-over-TLS (DoT)
tls://dns.google

# Plain DNS (fallback)
1.1.1.1
1.0.0.1

Bootstrap DNS servers:

1.1.1.1
1.0.0.1

Rate limiting: 20 requests per second per client
Enable DNSSEC validation
Save and apply

Step 3: Configure DNS Rewrites (Local DNS)

Objective

Point local hostnames to internal IPs so you can access services by name (e.g., http://proxmox.local).

Step-by-Step Instructions

Go to Filters → DNS rewrites
Add entries:

Domain	Answer
`proxmox.local`	`192.168.1.10`
`nas.local`	`192.168.1.20`
`pihole.local`	`192.168.1.30`
`jellyfin.local`	`192.168.1.40`

Test:

nslookup proxmox.local 192.168.1.10

Step 4: Router Configuration

Objective

Point your entire network to AdGuard Home for DNS.

Step-by-Step Instructions

Option A: Router DHCP (Recommended) 1. Log into your router (192.168.1.1 or 192.168.0.1) 2. Find DHCP Server or LAN Settings 3. Set Primary DNS to AdGuard Home IP (e.g., 192.168.1.10) 4. Secondary DNS: leave blank or use a backup AdGuard instance 5. Save and reboot the router

Option B: AdGuard Home DHCP Server If your router is locked (ISP-provided), let AdGuard Home handle DHCP: 1. Go to Settings → DHCP settings 2. Enable DHCP server 3. Set range: 192.168.1.100 to 192.168.1.200 4. Set gateway: 192.168.1.1 5. Set subnet mask: 255.255.255.0 6. Disable DHCP on your router 7. Renew all client leases

Pro Tips

Tip 1: Enable DNSSEC

In Settings → DNS settings, enable “DNSSEC validation.” This prevents DNS spoofing and ensures domain authenticity.

Tip 2: Use Per-Client Filtering

Go to Settings → Client settings and add clients by IP or MAC. You can assign different filtering rules to kids’ devices vs. adult devices.

Tip 3: Enable Safe Search

In Filters → DNS blocklists, enable the safe search option. This forces Google, Bing, YouTube, and DuckDuckGo to use safe search modes.

Tip 4: Add Custom Filtering Rules

AdGuard Home supports custom rules in AdGuard syntax:

# Block a specific domain
||example.com^

# Block a subdomain
||ads.example.com^

# Allow an exception
@@||safe.example.com^

# Redirect a domain
192.168.1.10 proxmox.local

Tip 5: Backup Your Configuration

# Backup the config directory
cd ~/docker/adguardhome
tar czvf adguard-backup-$(date +%F).tar.gz confdir workdir

# Restore: extract and restart container
tar xzvf adguard-backup-2026-06-05.tar.gz
docker compose restart

Troubleshooting Common Issues

Problem 1: “Dashboard Not Accessible After Setup”

Cause: Port 3000 is only for the initial setup wizard. After configuration, the UI runs on port 80 inside the container (mapped to 8080 on host).

Fix: Access http://your-server-ip:8080 after setup.

Problem 2: “DNS Queries Not Being Blocked”

Cause: Router not using AdGuard Home as DNS, or devices using hardcoded DNS.

Fix: - Check router DNS settings - For devices with hardcoded DNS (some Android TVs, Chromecast), use AdGuard Home’s “force safe search” or block port 53 outbound on your firewall

Problem 3: “Port 53 Already in Use”

Cause: systemd-resolved or another DNS service is bound to port 53.

Fix:

systemctl stop systemd-resolved
systemctl disable systemd-resolved
rm -f /etc/resolv.conf
ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf

Conclusion

Summary

AdGuard Home is a modern, powerful DNS ad blocker with built-in encrypted DNS, parental controls, and local DNS rewriting. The Docker Compose setup takes under 10 minutes and immediately improves privacy and ad blocking across your entire network.

Next Steps

Beelink Mini PC Proxmox: The Ultimate Self-Hosted Guide for 2026

2026-06-05T00:00:00+07:00

Reading time: ~12 minutes Audience: Homelabbers turning a Beelink mini PC into a Proxmox node

What Is Beelink Mini PC Proxmox?

Overview

Beelink is a leading Chinese manufacturer of compact, power-efficient mini PCs. Models like the SER5 (AMD Ryzen 5 5560U), SER6 (Ryzen 7 7735HS), and U59 (Intel N5105) are popular homelab choices because they cost $150–$400, idle at 6–15W, and fit in a network closet. Installing Proxmox VE turns these tiny boxes into full-featured virtualization hosts capable of running 5–15 VMs or dozens of LXC containers.

A Brief History

Beelink gained traction in the homelab community around 2022 after the Intel NUC supply crunch. The SER5 and SER6 series became the “go-to” for budget Proxmox builds because they offer 6–8 core CPUs, DDR4 SODIMM slots, and NVMe storage at half the price of a NUC. However, Proxmox installation on Beelink hardware requires BIOS tweaks and NIC driver awareness that standard guides skip.

Why Use Beelink Mini PC Proxmox?

Benefit 1: Extreme Power Efficiency

A Beelink SER6 idles at 8–12W. Under full CPU load, it peaks at 35–45W. Compare that to a used Dell R720 at 80–120W. Over a year, the Beelink costs about $12–18 in electricity, while the R720 costs $90–130. For a small homelab, the Beelink pays for itself in power savings within 18 months.

Benefit 2: Silent Operation

Beelink mini PCs use laptop-style cooling: a single heat pipe and a small blower fan. At idle, they are nearly silent (20–25 dB). Even under load, they are quieter than any rack server. This makes them ideal for living rooms, apartments, or offices.

Benefit 3: Low Cost of Entry

A used SER5 with 16 GB RAM and a 512 GB NVMe costs $180–250. That is less than a single enterprise CPU. You can build a 2-node Proxmox cluster for under $500, complete with Ceph or ZFS replication.

Installation

Prerequisites

Beelink mini PC (SER5, SER6, U59, or equivalent)
USB flash drive (8 GB+)
Proxmox VE 8.2 ISO (download from proxmox.com)
BalenaEtcher or Rufus (to write the ISO)
Keyboard and monitor (for initial BIOS/Proxmox install only)
Ethernet cable (Wi-Fi is not recommended for Proxmox hosts)

Method 1: Standard Installation

Download the Proxmox VE ISO and write it to the USB drive with BalenaEtcher.
Plug the USB into the Beelink and power on. Press F7 (or Del to enter BIOS) to select the USB boot device.
In the BIOS, make the following changes:
Boot Mode: UEFI (disable Legacy/CSM).
Secure Boot: Disable.
VT-d / AMD-Vi: Enable (for PCI passthrough later).
Above 4G Decoding: Enable (if available, helps with GPU passthrough).
Watchdog: Disable (can cause unexpected reboots on some Beelink units).
Boot the Proxmox installer. Choose “Install Proxmox VE.”
Disk selection: Select the internal NVMe or SSD. If you have two drives (e.g., NVMe + SATA), you can install Proxmox on the smaller drive and use the larger for VM storage.
Network config: Set a static IP. Use enp1s0 or eno1 as the primary interface. Note that Realtek NICs on some Beelink models may show as r8169.
Finish the install. Reboot and remove the USB.

Method 2: Headless Installation (Advanced)

If you cannot attach a monitor, you can install Debian 12 via preseed, then add the Proxmox repo. This is not recommended for beginners, but it works:

# After Debian 12 minimal install
su -
echo "deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription" > /etc/apt/sources.list.d/pve.list
wget https://enterprise.proxmox.com/debian/proxmox-release-bookworm.gpg -O /etc/apt/keyrings/proxmox-release-bookworm.gpg
apt update && apt install proxmox-ve

Basic Setup and Configuration

Step 1: First Boot and Web UI Access

After installation, the Beelink will boot into the Proxmox console. The screen shows the IP address. From another computer, open:

https://192.168.1.100:8006

Step 2: Update Proxmox

# On the Proxmox shell (or via web UI -> Shell)
apt update && apt dist-upgrade -y

Step 3: Fix Realtek NIC Stability

Some Beelink models (especially U59 and early SER5) use Realtek RTL8111H NICs that can drop packets under load. Proxmox uses the r8169 driver by default, but the r8168 driver is more stable.

# Install the r8168 driver from the Proxmox repo or compile it
apt install r8168-dkms
# Blacklist the old driver
echo "blacklist r8169" >> /etc/modprobe.d/blacklist.conf
update-initramfs -u
reboot

After reboot, verify:

ethtool -i enp1s0 | grep driver
# Should show r8168

Step 4: Configure Storage

Beelink units often have one NVMe and one SATA M.2 or 2.5” bay. Use the NVMe for Proxmox OS and VM disks, and the SATA SSD for backups or ISO storage.

# List disks
lsblk
# Create a ZFS pool on the second SSD (optional)
zpool create tank /dev/sdb
# Or add it as an LVM thin pool
pvcreate /dev/sdb
vgcreate vm-data /dev/sdb
lvcreate -l 100%FREE -T vm-data/thin

In the Proxmox web UI, go to Datacenter → Storage and add the new pool.

Step 5: Enable Nested Virtualization (for LXC or test VMs)

# Check if nested is enabled
cat /sys/module/kvm_intel/parameters/nested
# If N, enable it:
echo "options kvm_intel nested=1" > /etc/modprobe.d/kvm-nested.conf
modprobe -r kvm_intel kvm
modprobe kvm_intel

Advanced Features

Feature 1: GPU Passthrough (AMD iGPU)

Beelink SER5/SER6 use AMD Radeon integrated graphics. You can passthrough the iGPU to a Windows VM for light gaming or to a Linux VM for transcoding.

Requirements: - Enable AMD-Vi and IOMMU in BIOS. - Add amd_iommu=on to GRUB. - Blacklist the amdgpu driver on the host.

# /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on iommu=pt"
update-grub
reboot

In Proxmox, add the PCI device to the VM (via web UI → Hardware → Add → PCI Device). Use rombar=0 if the VM hangs.

Feature 2: USB Passthrough for Zigbee/Z-Wave

Beelink units have 4–6 USB ports. You can pass USB devices directly to VMs or LXC containers. For a Home Assistant VM:

# On Proxmox host

# Find your Zigbee coordinator (e.g., Silicon Labs CP210x)
# In VM Hardware -> Add USB Device -> Use Port or Vendor ID

Feature 3: Power Management

Set CPU governor to powersave for lower heat and noise:

apt install cpufrequtils
echo 'GOVERNOR="powersave"' > /etc/default/cpufrequtils
systemctl restart cpufrequtils

For AMD Ryzen, install amd-pstate driver if supported by your kernel for better frequency scaling.

Integrating with Your Homelab

Integration 1: Proxmox Cluster

You can cluster multiple Beelink units for HA. Each node needs a unique hostname, static IP, and matching Proxmox version.

# On the first node
pvecm create beelink-cluster
# On the second node
pvecm add 192.168.10.10

Warning: A 2-node cluster is not recommended for HA (quorum issues). Use a third node (even a Raspberry Pi with qdevice) or set expected votes to 1.

Integration 2: Backup to NAS

Use Proxmox Backup Server or vzdump to a Synology/NAS share:

# Mount an NFS share
mkdir /mnt/nfs-backup
mount -t nfs 192.168.10.5:/volume1/backup /mnt/nfs-backup
# Add to /etc/fstab for persistence

In the web UI, add Datacenter → Storage → NFS pointing to the share.

Alternatives to Consider

Alternative 1: Minisforum MS-01

The MS-01 has dual 10GbE SFP+ ports, an Intel i9-12900H, and a PCIe 4.0 x16 slot. It is the Beelink “upgrade” for users who need 10GbE or GPU expansion. It costs $600–800.

Alternative 2: Intel NUC 13 Pro

Intel’s NUC line is more expensive but offers Thunderbolt 4, better Linux driver support, and official Proxmox compatibility. A NUC13i5 costs $500–700 barebones.

Frequently Asked Questions

Question 1: Can I run Proxmox on a Beelink with only 8 GB RAM?

Yes, but it is tight. Proxmox itself uses ~2 GB. You can run 2–3 small LXC containers. For a comfortable lab, upgrade to 16 GB (max supported on most models is 32–64 GB).

Question 2: Does the Beelink support ECC RAM?

No. Beelink uses consumer SODIMMs (non-ECC). If you need ECC, move to a Supermicro or Rack server. For a small homelab, non-ECC is acceptable if you use ZFS and scrub regularly.

Question 3: Can I add a 2.5 GbE USB NIC?

Yes. USB 3.0 Realtek RTL8156B adapters work out of the box on Proxmox 8.x. Use them for a dedicated storage network or VLAN trunk.

Question 4: Will the Beelink overheat in a closet?

Ambient temperature matters. If your closet is above 30°C, the Beelink may throttle. Add a small USB fan or ensure passive ventilation. Use sensors to monitor temps:

apt install lm-sensors
sensors
# Look for k10temp (AMD) or coretemp (Intel)

Conclusion

Summary

Beelink mini PCs are the best-kept secret in the homelab world. They offer enough CPU, RAM, and storage for a small-to-medium Proxmox deployment at a fraction of the cost and power of a rack server. The installation is straightforward, but pay attention to BIOS settings (disable Secure Boot, enable IOMMU) and NIC driver stability (switch to r8168 if needed).

Best Rack Server for Homelab in 2026: A Curated Guide

2026-06-05T00:00:00+07:00

Reading time: ~14 minutes Audience: Homelab builders looking for rack-mounted server hardware

Why a Rack Server for Your Homelab?

A rack server gives you enterprise-grade reliability, expandability, and often multiple CPU sockets, hot-swap bays, and IPMI/iDRAC/iLO remote management. While mini PCs and tower servers are great for beginners, a rack server is the natural upgrade when you need more RAM slots, PCIe lanes, or storage bays. The used market is flooded with decommissioned datacenter gear, making it possible to build a 32-core, 128 GB RAM beast for less than a high-end mini PC.

Supermicro 5019D	1U	1× D-2146NT	512 GB DDR4	8× 2.5”	IPMI	35–50W	$700–$950

Pro Tips

Tip 1: Fan Quietening

Dell and HP servers default to aggressive fan curves. Use IPMI commands to set manual fan speeds. For Dell: ipmitool raw 0x30 0x30 0x02 0xff 0x0a sets 10% fan speed. Monitor temps; do not go below 10% if ambient is above 22°C.

Tip 2: HBA vs RAID

If you plan to run ZFS, TrueNAS, or Proxmox with Ceph, flash your RAID controller to IT mode (HBA). Dell H710 and HP P420i can both be cross-flashed. This gives direct disk access, which is critical for ZFS health monitoring.

Tip 3: Power Math

A dual E5 v2 server at 100W idle costs about $0.30/day ($9/month) at $0.13/kWh. An R730 at 70W idle is ~$6.50/month. A 1U Xeon D at 40W is ~$3.80/month. Factor power into your 5-year total cost of ownership.

Conclusion

Summary

For most homelabbers, the Dell R720 offers the best balance of price, performance, and community support. If you need modern DDR4 and lower power, the R730 is worth the premium. For a quiet, warranty-backed build, the Lenovo SR250 V2 is a solid new option. And if 10GbE is your priority, the Supermicro 5019D is unbeatable.

Our Recommendation

Budget build: Dell R720 with 2× E5-2660 v2, 64 GB DDR3, H710 (IT mode). ~$350.
Performance build: Dell R730 with 2× E5-2680 v4, 128 GB DDR4, H730. ~$750.

Best UPS for Home Server 2026: Power Protection for Your Homelab

2026-06-05T00:00:00+07:00

Reading time: ~12 minutes Audience: Home server owners who want clean power and graceful shutdowns

Why a UPS for Your Home Server?

A UPS (Uninterruptible Power Supply) does two critical things: it filters dirty power (surges, brownouts) and provides battery backup during outages long enough for your server to shut down gracefully. A hard shutdown can corrupt ZFS pools, damage databases, and kill spinning disks. A UPS is the cheapest insurance you can buy for your data.

Evaluation Criteria

Criteria	Why It Matters
VA / Watt Rating	VA is apparent power; Watts is real power. Match the wattage to your load, not just the VA.
Runtime	How long the UPS can power your load at 50% draw.
Topology	Line-interactive (common, good for homelab) vs. Online double-conversion (best, expensive).
Outlets	Ensure enough battery-backed outlets for server, switch, router, and modem.
USB / Network Management	USB or SNMP card lets the UPS signal the OS to shut down before battery depletion.
Pure Sine Wave	Critical for Active PFC power supplies in modern servers.
Expandability	Some APC units accept external battery packs (EBM) to extend runtime.

#1: APC Back-UPS Pro BR1500G

The BR1500G is the standard home server UPS. It offers 1500 VA / 865 W, 10 outlets, USB management, and APC’s PowerChute software. The LCD shows load percentage and runtime. It is reliable, widely available, and integrates seamlessly with NUT on Linux and Proxmox.

Specs: 1500 VA / 865 W | 10 outlets | ~12 min @ 50% | USB | $180–220

Best for: Small-to-medium home servers with a load under 500 W.

#2: CyberPower CP1500PFCLCD

The CP1500PFCLCD uses a pure sine wave inverter, which is critical for Active PFC power supplies. It offers 1500 VA / 900 W, 12 outlets, and a USB charging port. CyberPower’s software is Linux-friendly and supports NUT out of the box.

Specs: 1500 VA / 900 W | 12 outlets | ~10 min @ 50% | Pure sine | $170–210

Best for: Users with Active PFC PSUs who want pure sine wave on a budget.

#3: APC Smart-UPS SMT1500RM2U

For rack servers, the SMT1500RM2U is the industry standard. It is a 2U rackmount unit with 1500 VA / 1000 W, optional SNMP network card, and support for external battery modules. It is overkill for a mini PC but essential for a rack server.

Best VPS for Homelab 2026: Self-Hosting in the Cloud

2026-06-05T00:00:00+07:00

Reading time: ~14 minutes Audience: Homelabbers choosing a VPS to extend their self-hosted infrastructure

Why a VPS for Your Homelab?

A VPS (Virtual Private Server) is a rented virtual machine in a data center. For homelabbers, it solves three problems: 1. Public IP and open ports: Residential ISPs block port 25, 80, and 443. A VPS has all ports open. 2. Static IP: Most home ISPs use dynamic IPs. A VPS gives you a stable IP for DNS records. 3. Uptime and power: Data centers have redundant power and internet. Your services stay online even when your house loses power.

A VPS is not a replacement for your homelab — it is an extension. You run public-facing services (website, VPN, email) on the VPS while keeping private data (photos, documents, media) at home.

Cheap VPS for Self-Hosting 2026: Best Budget Cloud Servers for Homelabbers

2026-06-05T00:00:00+07:00

Reading time: ~14 minutes Audience: Homelabbers who want a public-facing VPS without breaking the bank

What Is a Cheap VPS for Self-Hosting?

A cheap VPS is a low-cost virtual private server ($3–10/month) that extends your homelab into the cloud. It provides a public IP, DDoS protection, and 24/7 uptime — things most residential ISPs cannot offer. For self-hosters, a VPS is the bridge between your private LAN and the public internet.

Why Use a Cheap VPS?

Public IP and Port Availability

Data centers provide static or stable IPs with all ports open. You can run an SMTP relay, a public-facing web server, or a game server without fighting CGNAT or ISP firewalls.

Geographic Diversity

Hosting a VPS in a different region lets you serve content closer to your users. A VPS in Frankfurt or New York can act as a CDN edge or a failover endpoint.

Offsite Backup Target

A VPS is an ideal offsite backup target. Run a MinIO container, a restic server, or a BorgBackup repository and schedule nightly backups from your homelab.

DNS Filtering in the Homelab: A Complete Guide to Network-Wide Ad Blocking

2026-06-05T00:00:00+07:00

Reading time: ~15 minutes Audience: Homelabbers who want to clean up their network traffic

What Is DNS Filtering?

What Exactly Is It?

DNS filtering is the practice of intercepting DNS queries — the requests your devices make to translate domain names like google.com into IP addresses — and blocking queries to known malicious, ad-serving, or tracking domains. Instead of returning the real IP address, the DNS filter returns 0.0.0.0 or NXDOMAIN, preventing the connection entirely.

This is the most efficient way to block ads because it happens at the network level. Every device on your network — phones, smart TVs, IoT devices, laptops — benefits without installing software on each device.

A Brief History

DNS-level ad blocking started with custom hosts files in the 1990s. In 2015, Pi-hole popularized the concept as a network-wide DNS sinkhole. By 2020, AdGuard Home emerged with a modern UI and native encrypted DNS support. Today, DNS filtering is a standard layer in every privacy-conscious network.

Why It Matters Today

Modern homes have 20–50 connected devices. Each one phones home to trackers, telemetry servers, and ad networks. DNS filtering: - Blocks ads on smart TVs where you cannot install ad blockers. - Stops IoT devices from leaking data to Chinese or US cloud servers. - Reduces bandwidth usage by preventing ad and tracking payloads from downloading. - Improves page load times by eliminating DNS lookups for blocked domains.

Why It Matters

Benefit 1: Network-Wide Protection

One DNS filter protects every device. A Pi-hole or AdGuard Home instance on a Raspberry Pi covers your entire LAN. No per-device configuration, no browser extensions, no VPN apps.

Benefit 2: Malware and Phishing Blocking

Blocklists like Hagezi, StevenBlack, and MalwareDomainList include known malicious domains. If a family member clicks a phishing link, the DNS filter blocks the resolution before any connection is made.

Benefit 3: Telemetry Reduction

Windows, Android, smart TVs, and IoT devices constantly send telemetry. DNS filters block domains like telemetry.microsoft.com, metrics.icloud.com, and crashlytics.com. Your devices still function; they just stop reporting.

Device	Common Telemetry Domains Blocked
Windows	`telemetry.microsoft.com`, `vortex.data.microsoft.com`
Android	`google-analytics.com`, `crashlytics.com`
Smart TV	`samsungads.com`, `vizio.com`
IoT	`tuya.com`, `Xiaomi cloud domains`

Core Principles

Principle 1: The DNS Sinkhole

Explanation

A DNS sinkhole is a DNS server that returns a false IP for blocked domains. When your phone asks for ads.google.com, the sinkhole returns 0.0.0.0. The phone tries to connect to 0.0.0.0, fails instantly, and the ad never loads. This is faster than waiting for the real server to timeout.

Example

Normal DNS flow:

Device → Router DNS (ISP) → Recursive resolver → Root → TLD → Authoritative → IP returned

Filtered DNS flow:

Device → Pi-hole/AdGuard (local) → Checks blocklist → If blocked, returns 0.0.0.0
                                         → If allowed, forwards to upstream resolver

Principle 2: Blocklists and Whitelists

Explanation

DNS filters use blocklists (also called “gravity lists” or “filter lists”) — text files containing millions of domains to block. The quality of your filtering depends on the lists you choose. Too few lists = ads leak through. Too many aggressive lists = false positives (legitimate sites break).

Example

Recommended blocklist combination for a balanced homelab:

Blocklist	Purpose	Size
StevenBlack	Ads, malware, tracking	~150K domains
OISD Full	Aggressive ad/tracker blocking	~200K domains
Hagezi Multi NORMAL	Balanced, low false positives	~300K domains
NoCoin Filter	Cryptojacking scripts	~15K domains
MalwareDomainList	Known malware domains	~25K domains

Whitelist essentials: - google.com (sometimes blocked by overzealous lists) - github.com (required for updates) - cdn.jsdelivr.net (used by many legitimate sites) - Your banking domains (add manually if broken)

Principle 3: Encrypted DNS (DoH/DoT)

Explanation

Standard DNS is unencrypted. Your ISP can see every domain you visit. DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) encrypt the DNS query between your filter and the upstream resolver. This prevents: - ISP snooping (selling your browsing data) - DNS hijacking (redirecting you to fake sites) - Man-in-the-middle attacks on DNS queries

Example

DNS-over-TLS (DoT) uses port 853 and wraps DNS in a TLS tunnel. DNS-over-HTTPS (DoH) uses port 443 and sends DNS queries as HTTPS requests. DoH is harder to block because it looks like normal web traffic.

Upstream resolvers supporting DoH/DoT: - https://dns.cloudflare.com/dns-query (Cloudflare) - https://dns.quad9.net/dns-query (Quad9, malware filtering) - https://dns.adguard-dns.com/dns-query (AdGuard, ad filtering) - tls://dns.google (Google)

Applying This to Your Homelab

Homelab Setup Example

“The Privacy-First Stack”

Services: - AdGuard Home (primary DNS sinkhole + DoH upstream) - Unbound (local recursive resolver for non-blocked queries) - WireGuard (remote DNS when away from home)

Configuration:

Router DHCP → DNS = AdGuard Home (192.168.1.2)
AdGuard Home → Upstream = 127.0.0.1:5335 (Unbound)
Unbound → Root servers (no third-party resolver)

This setup means: - Blocked domains: stopped at AdGuard Home. - Allowed domains: resolved recursively by Unbound (no Cloudflare, no Google, no ISP). - Mobile devices: use WireGuard to tunnel DNS back to AdGuard Home.

Practical Steps

# Step 1: Install AdGuard Home via Docker
docker run -d --name adguardhome \
  -p 53:53/tcp -p 53:53/udp \
  -p 80:80/tcp -p 443:443/tcp \
  -p 3000:3000/tcp -p 853:853/tcp \
  -v $(pwd)/workdir:/opt/adguardhome/work \
  -v $(pwd)/confdir:/opt/adguardhome/conf \
  --cap-add=NET_ADMIN \
  --restart=always \
  adguard/adguardhome:latest

# Step 2: Configure upstream DNS in AdGuard
# Settings → DNS settings → Upstream DNS servers
# Add: tls://dns.quad9.net
# Add: https://dns.cloudflare.com/dns-query

# Step 3: Install Unbound as a local recursive resolver
sudo apt install unbound
# Configure /etc/unbound/unbound.conf to listen on 127.0.0.1:5335

# Step 4: Set your router's DNS to the AdGuard Home IP
# Or configure DHCP to push the AdGuard IP as DNS

# Step 5: Test
nslookup doubleclick.net 192.168.1.2
# Should return 0.0.0.0

Common Mistakes to Avoid

Mistake 1: Using Only Default Blocklists

The default blocklists in Pi-hole and AdGuard Home are good but incomplete. Add OISD, Hagezi, and NoCoin for comprehensive coverage. Update lists weekly (automated in both tools).

Mistake 2: Blocking Too Aggressively

Aggressive lists like 1Hosts (Xtra) break Netflix, YouTube, and banking sites. Start with NORMAL or PRO lists. Only add Xtra if you are willing to maintain a large whitelist.

Mistake 3: Not Encrypting Upstream DNS

If your upstream DNS is unencrypted (8.8.8.8, 1.1.1.1), your ISP can still see your queries via SNI or traffic analysis. Always enable DoH or DoT. If you use Unbound, the queries are encrypted to root servers via DNSSEC (not transport encryption, but authenticity verified).

Conclusion

Summary

DNS filtering is the first layer of defense in a secure homelab. It blocks ads, malware, and telemetry for every device on your network — no client-side software required. AdGuard Home or Pi-hole paired with Unbound gives you a fast, private, and self-sufficient DNS infrastructure.

Next Steps

Deploy AdGuard Home or Pi-hole in Docker.
Add 3–5 blocklists (StevenBlack, OISD, Hagezi).
Enable DoH/DoT to encrypt upstream queries.
Install Unbound if you want recursive resolution without third parties.
Monitor query logs for a week to identify false positives.

Docker Compose vs Podman: Which One Wins for Your Homelab?

2026-06-05T00:00:00+07:00

Reading time: ~11 minutes Audience: Homelabbers choosing a container engine for self-hosted apps

The Docker Compose vs Podman Dilemma

Overview

Docker Compose is the de facto standard for multi-container apps. It uses a single docker-compose.yml file to define networks, volumes, and services. Podman is a daemonless, rootless container engine that is compatible with Docker CLI but does not require a background service. It is the default on Red Hat Enterprise Linux and Fedora, and it is gaining traction in security-focused homelabs.

Key Differences at a Glance

Feature	Docker Compose	Podman
Daemon	`dockerd` runs as root	Daemonless; containers run as user
Rootless	Possible but complex	Native and default
Compose	`docker-compose` (Python) or `docker compose` (Go plugin)	`podman-compose` (Python) or `podman-compose` (native)
Pods	Not native (uses “services”)	Native pod concept (like Kubernetes)
Systemd	Manual setup	Native `podman generate systemd`
Kubernetes	No	Can generate K8s YAML from pods
Image format	OCI	OCI (fully compatible)
Learning curve	Gentle	Moderate (different networking model)
Community	Massive	Growing fast; Red Hat backed

Option A: Docker Compose

Pros

Ecosystem dominance: Every self-hosting guide, GitHub repo, and blog post assumes Docker Compose. Copy-paste docker-compose.yml and it works.
Docker Hub: Largest image registry with one-click pulls.
Swarm mode: Optional built-in clustering for multi-node setups.
Rich tooling: Portainer, Watchtower, and Diun are built around Docker.
Volume management: Named volumes and bind mounts are well-documented and stable.
Networking: docker network create and service discovery are automatic.

Cons

Root daemon: dockerd runs as root. A container escape can compromise the host.
Docker Desktop licensing: On macOS/Windows, commercial use requires a paid license (Linux is free).
Socket security: The Docker socket (/var/run/docker.sock) is a well-known attack vector.
Image bloat: Official images often include more than needed; scanning is essential.

Best For

Users who want maximum compatibility with existing guides and tools.
Homelabs with many apps managed via Portainer or Dockge.
Teams who need to share docker-compose.yml files without explanation.

Pricing

Free on Linux (Docker Engine).
Docker Desktop: free for personal use; paid for companies ($5/user/month).

Option B: Podman

Pros

Rootless by default: Containers run as your user. Even if a container is compromised, the attacker has your user privileges, not root.
Daemonless: No background service. Containers are child processes of your shell. If you log out, containers stop (unless you use podman generate systemd).
Pod concept: Group containers into pods that share a network namespace. This mirrors Kubernetes and makes migration easier.
Systemd integration: podman generate systemd --new creates unit files that auto-start on boot.
Docker CLI compatible: alias docker=podman works for 90% of commands.
No socket required: Podman does not expose a Unix socket, eliminating a major attack vector.

Cons

Compose support: podman-compose is a Python wrapper around Docker Compose. It works for most files but has edge cases (e.g., depends_on health checks, build contexts).
Networking model: Rootless containers use slirp4netns or pasta for networking. Port forwarding and DNS behave differently than Docker.
Smaller community: Fewer homelab guides target Podman. You may need to adapt Docker tutorials.
Volume permissions: Rootless UID mapping can cause permission issues with bind mounts (e.g., Plex media folders).

Best For

Security-conscious users who want to minimize root access.
Fedora, RHEL, and CentOS Stream users (Podman is pre-installed).
Users who want to experiment with Kubernetes pods locally.

Pricing

Free (Apache 2.0 license).

Option C: The Podman + Docker Compose Path

Pros

Podman can run Docker Compose files directly with podman compose (via the podman-compose plugin or the Docker Compose CLI plugin).
This gives you the security of Podman with the ecosystem of Docker Compose.
You can migrate incrementally: keep your docker-compose.yml files and switch the engine.

Cons

podman-compose is not 100% compatible. Complex builds, network_mode: host, and some health checks may fail.
You need to install podman-docker package for full CLI compatibility.

Best For

Users who want to test Podman without rewriting their entire stack.

Pricing

Free.

Comparison Matrix

Use Case	Docker Compose	Podman	Winner
Copy-paste from Reddit	✅	❌ May need tweaks	Docker Compose
Security / rootless	❌ Complex	✅ Native	Podman
Systemd auto-start	✅ Manual	✅ Native	Podman
Kubernetes learning	❌	✅ Pods + K8s YAML	Podman
Portainer / Dockge	✅ Native	❌ Limited	Docker Compose
Windows / macOS	✅ Docker Desktop	❌ Linux only (mostly)	Docker Compose
Image building	✅ `docker build`	✅ `podman build`	Tie

Which Should You Choose?

Scenario 1: “I just want to run Immich, Jellyfin, and Nextcloud.”

Choose Docker Compose. The docker-compose.yml files from the official docs will work without modification. Portainer gives you a GUI, and Watchtower keeps images updated.

Scenario 2: “I run Fedora on my home server and want maximum security.”

Choose Podman. Use podman-compose for your existing stacks. Generate systemd units for auto-start. Enjoy rootless containers and no daemon.

Scenario 3: “I plan to move to Kubernetes eventually.”

Choose Podman. Its pod concept is a stepping stone to Kubernetes. You can export pods to YAML and import them into a K3s cluster later.

Migration Path: Docker to Podman

Step 1: Install Podman

# Debian/Ubuntu
sudo apt install podman podman-compose podman-docker

# Fedora
sudo dnf install podman podman-compose

Step 2: Test Your Compose File

# In your app directory
podman-compose up -d
# Check logs
podman-compose logs -f

Step 3: Fix Common Issues

Port binding: Rootless Podman cannot bind ports < 1024. Use 8080:80 instead of 80:80.
DNS: Use podman network create and attach containers to it. Rootless DNS is less automatic than Docker.
Volumes: Ensure the host directory is owned by your user. Use :Z for SELinux labels: “`yaml volumes:
- ./data:/data:Z “`

Step 4: Generate Systemd Units

# Create a systemd unit for auto-start
podman generate systemd --new --name mycontainer > ~/.config/systemd/user/mycontainer.service
systemctl --user enable mycontainer.service
systemctl --user start mycontainer.service

The Verdict

Verdict	Recommendation
Best for beginners	Docker Compose (guides, GUIs, community)
Best for security	Podman (rootless, daemonless, no socket)
Best for Red Hat ecosystems	Podman (native, supported, pre-installed)
Best long-term flexibility	Podman (pods, K8s export, systemd)

Conclusion

Summary

Docker Compose is the easy button. It works everywhere, and everyone writes guides for it. Podman is the secure, future-proof option. It is harder to learn but pays dividends in security and systemd integration. If you are on Ubuntu/Debian and want to get apps running today, use Docker Compose. If you are on Fedora or RHEL and care about rootless security, use Podman.

# docker-compose.yml
    env_file:
      - .env

Tip 2: Connect Grafana to Multiple Data Sources

Add InfluxDB, Loki, MySQL, or PostgreSQL as additional data sources. You can mix data from multiple sources in a single dashboard.

Tip 3: Set Up a Reverse Proxy

Expose Grafana through NGINX Proxy Manager or Traefik for HTTPS and custom domains:

https://grafana.yourdomain.com → http://grafana:3000

Tip 4: Use Dashboard Folders

Organize dashboards by category: - Infrastructure (Node Exporter, Proxmox) - Applications (Nextcloud, Jellyfin, Pi-hole) - Security (Wazuh, CrowdSec) - Networking (UniFi, Omada)

Troubleshooting Common Issues

Problem 1: “Dashboard Shows No Data”

Cause: Data source not configured, or queries are wrong.

Fix: - Verify data source at Configuration → Data sources - Test the query in the Explore tab - Check Prometheus targets at http://prometheus:9090/targets

Problem 2: “Permission Denied on Data Directory”

Cause: Grafana container runs as UID 472 but host directory is owned by root.

Fix:

chown -R 472:472 ~/docker/grafana/data

Problem 3: “Forgot Admin Password”

Fix:

docker exec -it grafana grafana-cli admin reset-admin-password newpassword

Conclusion

Summary

Grafana turns raw metrics into actionable insights. With Docker Compose, you can deploy it in minutes, import community dashboards, and build custom views of your homelab. Combined with Prometheus, it gives you professional-grade observability.

Homelab Networking Basics: A Complete Visual Guide for Self-Hosters

2026-06-05T00:00:00+07:00

Reading time: ~13 minutes Audience: Beginners who want to understand how data moves inside their homelab

What Is Homelab Networking?

What Exactly Is It?

Homelab networking is the practice of building and managing a local network that supports your self-hosted servers, VMs, containers, and IoT devices. It goes beyond a simple Wi-Fi router: you create subnets, isolate services with VLANs, and forward traffic with reverse proxies. Good networking is the foundation that makes your homelab secure, fast, and scalable.

A Brief History

In 2000, a home network was a single router and a few PCs. By 2010, NAS devices and media servers introduced the need for static IPs and port forwarding. Today, a modern homelab may have 50+ devices (VMs, containers, smart home gear), making flat networks a security and broadcast nightmare. VLANs, managed switches, and OPNSense/PfSense are now standard.

Why It Matters Today

Without a structured network, every device can see every other device. A compromised IoT bulb can scan your NAS. A misconfigured firewall can expose your dashboard to the internet. Proper networking is the difference between a toy and a production-grade lab.

Why It Matters

Benefit 1: Security Isolation

VLANs let you segment your network into logical zones. Your servers, IoT devices, and guest Wi-Fi can be isolated so they cannot talk to each other unless you explicitly allow it. If a cheap camera is hacked, it cannot reach your Proxmox host or your file server.

Benefit 2: Traffic Management

Subnetting reduces broadcast traffic. In a flat /24 network (254 hosts), every ARP request hits every device. Splitting into /26 subnets (62 hosts each) keeps broadcast noise local and improves performance.

Benefit 3: Simplified Access Control

Firewall rules are easier to write when you know that 192.168.10.0/24 is “servers” and 192.168.20.0/24 is “IoT.” You can apply a single rule: “Allow IoT to internet, but deny IoT to Servers.” No per-device IP management needed.

Core Principles

Principle 1: IP Addressing & Subnetting

Explanation

Every device on your network needs an IP address. The address is split into a network portion and a host portion. A subnet mask (e.g., 255.255.255.0 or /24) defines where the split occurs.

Common homelab subnets:

Subnet	Mask	Usable Hosts	Typical Use
`192.168.1.0/24`	`255.255.255.0`	254	Default router LAN
`192.168.10.0/24`	`255.255.255.0`	254	Servers & VMs
`192.168.20.0/24`	`255.255.255.0`	254	IoT devices
`10.0.0.0/24`	`255.255.255.0`	254	VPN/tunnel network
`10.10.10.0/24`	`255.255.255.0`	254	Guest network

Example

You have a Proxmox host at 192.168.10.10 and a Pi-hole container at 192.168.10.2. Both are in the same /24, so they communicate directly through the switch. Your router at 192.168.1.1 needs a static route or a VLAN interface to reach 192.168.10.0/24.

Principle 2: VLANs (Virtual LANs)

Explanation

A VLAN tags Ethernet frames with a numeric ID (1–4094). A managed switch uses this ID to decide which ports belong to which logical network. You can have multiple VLANs on a single physical cable using 802.1Q trunking.

Typical VLAN design for a homelab:

VLAN ID	Name	Purpose	Subnet
1	Default	Router, switches	`192.168.1.0/24`
10	Servers	Proxmox, NAS, VMs	`192.168.10.0/24`
20	IoT	Cameras, bulbs, sensors	`192.168.20.0/24`
30	Guest	Wi-Fi for visitors	`192.168.30.0/24`
40	Management	IPMI, iDRAC, switch admin	`192.168.40.0/24`

Example

On a TP-Link Omada or UniFi switch, you configure: - Port 1: Trunk (carries VLANs 1, 10, 20, 30, 40) - Port 2: Access VLAN 10 (connects to Proxmox host) - Port 3: Access VLAN 20 (connects to IoT hub)

On Proxmox, you create a Linux bridge vmbr0 with a VLAN-aware interface, then assign VLAN tags to VMs:

# /etc/network/interfaces snippet on Proxmox
auto vmbr0
iface vmbr0 inet static
    address 192.168.10.10/24
    gateway 192.168.10.1
    bridge-ports enp3s0
    bridge-vlan-aware yes
    bridge-vids 2-4094

# Then assign a VM to VLAN 20 via the web UI

Principle 3: Firewall Rules

Explanation

A firewall controls which traffic can cross between subnets or leave your network. In a homelab, the firewall is usually your router (OPNSense, pfSense, OpenWrt, or a UniFi Gateway). Rules are evaluated top-down and are default deny (implicitly block unless allowed).

A typical rule set for the IoT VLAN:

Allow IoT → Internet (any)
Allow IoT → DNS server (port 53) on Servers VLAN
Deny IoT → Servers VLAN (any)
Deny IoT → Management VLAN (any)

Example

In pfSense, under Firewall → Rules → IoT, you would add:

Action	Protocol	Source	Port	Destination	Port	Description
Pass	TCP/UDP	IoT net	*	Internet	*	Allow outbound
Pass	TCP/UDP	IoT net	*	192.168.10.2	53	DNS to Pi-hole
Block	*	IoT net	*	Servers net	*	Block servers
Block	*	IoT net	*	Mgmt net	*	Block management

Applying This to Your Homelab

Homelab Setup Example

Imagine a small apartment homelab: - Router: OPNSense on a mini PC (4 NICs) - Switch: 8-port managed Gigabit switch (VLAN-aware) - Server: Proxmox host (1 NIC, VLAN trunk) - Wi-Fi: UniFi AP (SSID “Home” on VLAN 10, “IoT” on VLAN 20, “Guest” on VLAN 30)

Traffic flow: 1. Your phone connects to “Home” (VLAN 10). It gets IP 192.168.10.50. 2. You open the Proxmox web UI at 192.168.10.10. Both are on VLAN 10, so the switch forwards directly. 3. Your smart bulb connects to “IoT” (VLAN 20). It gets IP 192.168.20.15. 4. The bulb tries to reach 192.168.10.10. The firewall blocks it. 5. The bulb resolves DNS via 192.168.10.2 (Pi-hole) because the firewall allows port 53.

Practical Steps

Assign subnets to each VLAN. Document them in a spreadsheet.
Configure VLANs on your router and switch. Test with a laptop on each VLAN.
Set static IPs for critical infrastructure (Proxmox, NAS, DNS, gateway). Use DHCP reservations.
Write firewall rules from most restrictive (IoT) to least restrictive (Servers).
Test with ping and nmap from each VLAN to ensure isolation works.

# From a device on the IoT VLAN, test connectivity
ping 192.168.10.2      # Should fail (firewall block)
ping 1.1.1.1           # Should succeed (internet allowed)
nslookup google.com 192.168.10.2  # Should succeed (DNS allowed)

Common Mistakes to Avoid

Mistake 1: Using the Default VLAN for Everything

Leaving all devices on VLAN 1 makes isolation impossible. Create dedicated VLANs before you have 50 devices to migrate.

Mistake 2: Forgetting the Default Gateway

A VM on VLAN 10 needs its default gateway set to 192.168.10.1 (the router’s VLAN interface). If the gateway is wrong, the VM can talk to local peers but cannot reach the internet.

Mistake 3: Over-Complicating with Too Many VLANs

You do not need a VLAN for every container. A good starting point is: Management, Servers, IoT, Guest. Add more only when you have a clear security reason.

Conclusion

Summary

Homelab networking is not magic; it is structured IP addressing, VLAN tagging, and firewall rules. Start with a flat network, then add VLANs as you grow. The most secure lab is one where every device has the least privilege it needs to function.

Homelab Server Hardware 2025: Building the Perfect Self-Hosted Machine

2026-06-05T00:00:00+07:00

Reading time: ~16 minutes Audience: Anyone building or upgrading a homelab server

What Is Homelab Server Hardware?

Overview

Homelab server hardware is the physical machine that runs your self-hosted services. In 2025, the landscape has shifted dramatically: mini PCs based on Intel N100/N305 chips have replaced old rack servers for most users. The only reasons to buy a full rack server today are if you need 64+ GB RAM, multiple GPUs, or 10+ hard drives.

Why It Matters Today

Electricity costs are rising. A Dell R720 draws 150W+ idle and costs $200+/year in power. A Beelink EQ12 (Intel N100) draws 8W idle and costs $12/year. The performance gap has closed enough that a mini PC can handle Proxmox, Docker, media streaming, and file hosting for most households.

Pro Tips

Tip 1: Measure Your Power Before Buying

Use a Kill-A-Watt meter to measure your current setup. If you are under 50W, a mini PC is perfect. If you are over 100W, consider a tower server or custom build.

Tip 2: Prioritize QuickSync for Media Servers

If you run Jellyfin, Plex, or Immich, Intel QuickSync is essential. AMD Ryzen does not have QuickSync. An Intel N100, N305, or i3-12100 is ideal.

Tip 3: Buy Used Enterprise SSDs for Boot

Used enterprise SSDs (Intel S4510, Samsung PM883) are cheap, reliable, and have high write endurance. A 240 GB enterprise SSD costs ~$20 used and outlasts a consumer SSD.

Conclusion

Summary

For most homelabbers in 2025, a mini PC with an Intel N100 or N305 is the best choice. It is silent, cheap, and powerful enough for Docker, Proxmox, and media streaming. If you need 32+ GB RAM, multiple hard drives, or IPMI, a tower server or custom build is the next step. Rack servers are only justified for certification labs or massive virtualization.

Our Recommendation

First homelab (Docker + 3–5 services): Intel N100 mini PC ($150–200)
Proxmox + 4–6 VMs: Intel N305 mini PC or custom i3 build ($250–400)
NAS + 6+ drives + ECC: Used tower server or custom build ($400–800)

Homelab Server Hardware 2026: The Complete Build Guide

2026-06-05T00:00:00+07:00

Reading time: ~15 minutes Audience: Anyone planning a new homelab build or upgrade

What Is Homelab Server Hardware?

What Exactly Is It?

Homelab server hardware is the physical infrastructure you use to run self-hosted services. It ranges from a $150 mini PC to a $2,000 rack server. Unlike a desktop PC, homelab hardware is chosen for 24/7 uptime, power efficiency, remote management, and virtualization support. The right hardware depends on your workload: a DNS server needs almost nothing, while a 4K Plex server with AI transcoding needs a modern GPU.

A Brief History

In 2015, a homelab was often an old desktop or a Dell OptiPlex. By 2020, the Intel NUC dominated small labs. In 2024–2026, the market exploded with Chinese mini PCs (Beelink, Minisforum), ARM servers (Raspberry Pi 5), and affordable used enterprise gear (Dell R730). The result is that you can build a capable lab for any budget.

Why It Matters Today

Choosing the wrong hardware leads to three problems: 1. Over-spending: Buying a $1,500 rack server when a $300 mini PC would suffice. 2. Power bills: An old R710 at 200W idle costs $200+/year in electricity. 3. Scalability walls: A 4-core NUC with 16 GB RAM cannot grow with your needs.

This guide helps you match hardware to your actual use case.

Why It Matters

Benefit 1: Total Cost of Ownership

A cheap server that uses 200W costs more over 3 years than an efficient one. Consider upfront cost + electricity + cooling. A $300 mini PC at 15W is cheaper than a free R710 at 200W.

Benefit 2: Learning Relevance

Enterprise hardware (iDRAC, RAID, IPMI) teaches you skills that transfer directly to sysadmin and DevOps roles. Consumer hardware teaches you less about remote management.

Benefit 3: Scalability

A 2U rack server with 24 RAM slots can scale from 16 GB to 768 GB without replacing the motherboard. A mini PC with 2 SODIMM slots maxes out at 64 GB.

Core Principles

Principle 1: CPU Selection

Explanation

The CPU is the heart of your homelab. For virtualization, you care about core count, thread count, and features like VT-x/AMD-V (virtualization), VT-d/AMD-Vi (PCI passthrough), and AES-NI (encryption).

Tiers for 2026:

Tier	CPU Example	Cores/Threads	TDP	Best For
Budget	Intel N100 / N305	4C/4T or 8C/8T	6–15W	2–4 VMs, LXC containers
Mid-range	AMD Ryzen 5 5560U / 7 7735HS	6C/12T or 8C/16T	15–35W	8–12 VMs, light transcoding
Performance	Intel Xeon E5-2680 v4	14C/28T	120W	20+ VMs, heavy compute
Enthusiast	AMD Ryzen 9 7950X / Threadripper	16C/32T+	65–170W	GPU passthrough, AI, massive VMs

Example

A Proxmox host running Pi-hole, Nextcloud, and Jellyfin needs ~4 cores. A host running 10 Windows VMs for a test lab needs 16+ cores.

Principle 2: RAM Selection

Explanation

RAM is the most common bottleneck in homelabs. Every VM consumes RAM. ZFS (a popular filesystem) uses RAM for ARC cache. A good rule of thumb:

Base OS: 2–4 GB for Proxmox or TrueNAS.
Per VM: 2–4 GB for Linux, 4–8 GB for Windows.
ZFS ARC: 1 GB per TB of storage (or 50% of total RAM, whichever is smaller).

RAM types: - DDR3 ECC: Cheap, used in R720/R730. Good for budget builds. - DDR4 ECC: Modern, used in R730/R740 and AMD EPYC. Best balance. - DDR5 ECC: Cutting edge, expensive. Used in Ryzen 7000 and Intel Xeon W. - Non-ECC SODIMM: Used in mini PCs. Fine for small labs, but no error correction.

Example

A mini PC with 32 GB DDR4 can run 8–10 LXC containers. A rack server with 128 GB DDR4 can run 20+ VMs with headroom.

Principle 3: Storage Strategy

Explanation

Storage is about speed, capacity, and redundancy. Most homelabs use a tiered approach:

Tier	Media	Use Case	Speed
Boot	256–512 GB NVMe	Proxmox OS, VM disks	3,000+ MB/s
VM Storage	1–2 TB NVMe or SSD	Active VM disks, databases	500–3,500 MB/s
Bulk Storage	4–20 TB HDD (3.5”)	Media, backups, archives	150–200 MB/s
Cold Storage	External USB or offsite	Long-term backups	N/A

Redundancy options: - ZFS: Software RAID with checksums, snapshots, and compression. Best for TrueNAS or Proxmox. - Hardware RAID: Dell PERC, HP Smart Array. Good for Windows VMs, but avoid for ZFS. - Single disk + backups: Acceptable for small labs with good 3-2-1 backups.

Example

A 4-drive ZFS pool of 4 TB HDDs in RAID-Z1 gives you 12 TB usable. Add an L2ARC SSD for cache and a ZIL NVMe for sync writes.

Applying This to Your Homelab

Homelab Setup Example

The $400 Mini PC Lab: - CPU: Intel N100 (4 cores, 6W) - RAM: 16 GB DDR4 SODIMM (upgrade to 32 GB later) - Boot: 512 GB NVMe - Storage: 2 TB 2.5” SSD (for VMs) - Network: 1x 1GbE (add a 2.5 GbE USB NIC if needed) - OS: Proxmox VE - Services: Pi-hole, Nextcloud, Jellyfin, Immich (light use)

The $1,200 Rack Lab: - Server: Dell R730 (2x E5-2680 v4, 128 GB DDR4) - Boot: 2x 480 GB SSD (RAID-1) - Storage: 6x 4 TB HDD (ZFS RAID-Z2) + 2x 1 TB NVMe (L2ARC/ZIL) - Network: 2x 10GbE SFP+ (Mellanox ConnectX-3) - UPS: APC Smart-UPS 1500 VA - Switch: 8-port 10GbE SFP+ managed switch - Services: 20+ VMs, Kubernetes, Plex (4K transcoding), ZFS NAS

Practical Steps

List your planned services and estimate their RAM/CPU needs.
Choose a form factor: Mini PC (silent), Tower (expandable), or Rack (enterprise).
Pick a CPU with virtualization support and enough cores.
Buy RAM in matched pairs. For ZFS, allocate 1 GB per TB of storage.
Design storage: Use NVMe for speed, HDD for bulk, and ZFS for integrity.
Plan networking: 1GbE is fine for most. Add 2.5 GbE or 10GbE if you transfer large files.
Buy a UPS sized to your load (see our UPS guide).

# Estimate your power draw
# Mini PC: 10-15W idle
# Rack server: 80-150W idle
# Per HDD: 5-8W
# Per NVMe: 3-5W
# Total = sum of all components

Common Mistakes to Avoid

Mistake 1: Buying Old, Power-Hungry Gear

A Dell R710 (2009) is free on Craigslist but uses 200W idle. Over 3 years, that costs $700 in electricity. A $300 mini PC at 15W costs $50. Do the math.

Mistake 2: Ignoring ECC RAM

For ZFS and TrueNAS, ECC is strongly recommended. It prevents silent corruption. If you use non-ECC, scrub your pools weekly and keep backups.

Mistake 3: Using Consumer SSDs for 24/7 Write Loads

QLC and TLC consumer SSDs wear out quickly under constant writes (databases, ZFS SLOG). Use datacenter SSDs (Intel D3, Samsung PM893) or dedicated NVMe for write-heavy tasks.

Conclusion

Summary

Homelab hardware in 2026 is divided into three tiers: - Mini PC ($150–400): Perfect for beginners, silent, low power. - Tower / Workstation ($400–800): Good expandability, mid-range CPUs. - Rack Server ($200–2,000): Maximum power, remote management, but loud and power-hungry.

Match your hardware to your workload. A mini PC is enough for most personal labs. A rack server is only justified if you need 20+ VMs, heavy I/O, or enterprise features.

Immich vs Google Photos: The Ultimate Self-Hosted Photo Backup Comparison

2026-06-05T00:00:00+07:00

Reading time: ~14 minutes Audience: Users considering leaving Google Photos for a self-hosted alternative

The Immich vs Google Photos Dilemma

Overview

Google Photos is the most popular photo backup service in the world. It offers unlimited storage (for compressed photos), powerful AI search, and seamless mobile apps. But it comes with a cost: your photos are mined for data, used to train AI models, and locked behind Google’s account system.

Immich is the open-source answer. It offers automatic mobile backup, AI-powered facial recognition, timeline and map views, and album sharing — all on your own hardware. The question is: can Immich truly replace Google Photos for everyday users?

Key Differences at a Glance

Feature	Google Photos	Immich (Self-Hosted)
Storage cost	$0–$20/month (Google One)	One-time hardware cost
AI face recognition	✅ Industry-leading	✅ Good (local ML)
Object/scene search	✅ “dogs at beach”	✅ “beach” works; “dogs at beach” limited
Mobile auto-upload	✅ Instant	✅ Background (iOS/Android)
Live photos	✅ Full support	✅ Supported (iOS)
RAW/DNG support	✅ Yes	✅ Yes
Video transcoding	✅ Automatic	✅ Configurable (FFmpeg)
Album sharing	✅ Easy links	✅ Shared links + partner sharing
Privacy	❌ Google scans photos	✅ Your data stays local
Offline access	❌ Requires internet	✅ LAN-only works
Export/migration	❌ Google Takeout is messy	✅ Files are just files on disk

Option A: Google Photos

Pros

Best-in-class AI search: Type “birthday cake 2023” and find the exact photo. Google’s AI is years ahead of open-source alternatives.
Unlimited compressed storage: The “Storage Saver” tier offers free unlimited backups at reduced quality.
Seamless ecosystem: Photos sync to Google Drive, appear in Google Docs, and integrate with Android.
Reliability: Google’s infrastructure is bulletproof. Your photos are replicated across continents.
Editing tools: Built-in cropping, filters, and auto-enhance are polished.

Cons

Privacy nightmare: Google scans your photos for objects, faces, locations, and text. This data feeds ad targeting and AI training.
Account lock-in: If your Google account is banned (false positive, payment issue), you lose access.
Compression: Storage Saver reduces quality. Original quality requires a paid plan.
No true ownership: You cannot directly access the raw files without Google Takeout, which is a zip-of-zips mess.
Geofencing risks: Google knows exactly where every photo was taken.

Best For

Users who prioritize convenience and AI search over privacy.
Families who do not want to manage a server.
Users with thousands of photos who cannot afford a NAS.

Pricing

Plan	Storage	Price
Google One Basic	100 GB	$1.99/month
Google One Standard	200 GB	$2.99/month
Google One Premium	2 TB	$9.99/month
Storage Saver	Unlimited	Free (compressed)

Option B: Immich

Pros

True privacy: Your photos never leave your hardware. No AI training, no ad targeting, no geolocation mining.
No subscription fees: Buy a hard drive once. A 4 TB drive stores ~1 million photos and costs ~$80.
Full quality: Every photo is stored at original resolution. No compression, no re-encoding.
AI features (local): Facial recognition, duplicate detection, object detection, and smart search — all run on your server via machine learning models.
Open source: MIT license. You can audit the code, modify it, and self-host indefinitely.
Partner sharing: Share a library with a partner so both phones auto-upload to the same Immich instance.
Map and timeline views: Beautiful, fast, and functional — comparable to Google Photos.

Cons

Server required: You need a mini PC, NAS, or VPS running 24/7. This is a hardware and power cost.
AI search is weaker: “Show me photos of my dog at the park” is harder than in Google Photos. Simple searches (“beach”, “car”, “person”) work well.
Setup complexity: You must install Docker, configure PostgreSQL, Redis, and machine learning containers.
Mobile app limitations: The iOS app is excellent but occasionally misses background uploads. Android is more reliable.
No ecosystem: Immich does not integrate with email, documents, or calendars.

Best For

Privacy-conscious users who want full ownership of their photos.
Homelabbers who already run a server.
Photographers who want original-quality backups without cloud subscriptions.

Pricing

Component	Cost (one-time)
Mini PC / NAS	$150–300
4 TB hard drive	~$80
Electricity	~$1–2/month
Software	Free (open source)
Total 3-year cost	~$230–380

Compare to Google One 2 TB: $9.99 × 36 = $360. Immich breaks even in ~3 years and then saves money.

Migration Path

Step 1: Export from Google Photos

Use Google Takeout: 1. Go to Google Takeout. 2. Select Google Photos. 3. Choose Export once → Maximum 2 GB per file. 4. Wait for the email (can take hours to days). 5. Download and extract the ZIP files.

Pro tip: The metadata (EXIF, timestamps) is in JSON sidecar files. Immich will read these during import.

Step 2: Prepare Immich

Follow our Immich Docker Compose setup guide. Ensure: - PostgreSQL and Redis are running. - The upload directory has enough space (2–3× your photo library size). - Machine learning is enabled for facial recognition.

Step 3: Import Photos

In the Immich web UI: 1. Go to Administration → Jobs. 2. Use the Import feature or drag-and-drop into albums. 3. Wait for thumbnail generation and facial recognition (can take hours for large libraries).

Step 4: Configure Mobile Auto-Upload

iOS: Enable background app refresh and location permissions. Immich uses geofencing to trigger uploads.
Android: Enable battery optimization exemption. The upload service runs reliably in the background.

The Verdict

Verdict	Recommendation
Best for privacy	Immich
Best for AI search	Google Photos
Best for non-technical users	Google Photos
Best for homelabbers	Immich
Best for photographers	Immich (original quality)
Best long-term cost	Immich

Conclusion

Summary

Google Photos is the convenient choice. Immich is the sovereign choice. For users who already run a homelab, Immich is a no-brainer: it delivers 90% of Google Photos’ functionality with 100% privacy and zero subscriptions. The AI gap is closing rapidly — by 2026, Immich’s facial recognition and object detection are already good enough for daily use.

Intel N100 Mini PC for Homelab: The Perfect Entry-Level Server

2026-06-05T00:00:00+07:00

Reading time: ~12 minutes Audience: Beginners and budget-conscious homelabbers

What Is the Intel N100 Mini PC?

What Exactly Is It?

The Intel N100 is a quad-core, quad-thread Alder Lake-N processor launched in early 2023. It is part of Intel’s “Intel Processor” branding (replacing Celeron/Pentium) and is designed for low-cost, low-power devices. Despite its humble positioning, the N100 has become a cult favorite in the homelab community for running 24/7 services.

A Brief History

Before the N100, homelabbers on a budget relied on Raspberry Pi 4 (ARM, limited RAM) or expensive Intel NUCs. The N100 changed the game by delivering x86 compatibility, 16GB DDR5 support, and 2.5GbE networking in a $150–$200 package. By 2026, it has become the default recommendation for first-time homelab builders.

Why It Matters Today

The N100 offers a rare combination of: - x86_64 architecture (runs any Linux/Windows software) - Low power (6–8W idle) - Modern connectivity (2.5GbE, USB 3.2, NVMe) - Adequate CPU (4 cores, enough for 5–10 Docker containers) - Low cost ($150–$200 for a complete system)

For the price of a Raspberry Pi 5 kit with accessories, you get a fully capable x86 server with better I/O.

Why It Matters

Benefit 1: Unmatched Price-to-Performance for Beginners

At $150–$200, the N100 mini PC delivers more computing power per dollar than any other homelab entry point. You get a full Debian/Proxmox host that can run Pi-hole, Nextcloud, Jellyfin, and Home Assistant simultaneously.

Benefit 2: Silent 24/7 Operation

Most N100 mini PCs are fanless or use a tiny blower that is inaudible at 1 meter. This means you can run it in a bedroom, living room, or closet without noise complaints. A used rack server at 40 dB(A) is a non-starter in apartments.

Benefit 3: Modern Networking and Storage

Unlike older NUCs or Celeron J4125 systems, the N100 supports: - 2.5GbE (2.5x faster than Gigabit on supported models) - NVMe Gen3 x4 (up to 3,500 MB/s read) - DDR5-4800 (faster memory bandwidth than DDR4) - USB 3.2 Gen2 (10 Gbps for external storage)

Spec	N100	Raspberry Pi 5	Celeron J4125
CPU	4C/4T Alder Lake-N	4C/4T ARM Cortex-A76	4C/4T Gemini Lake
RAM	16GB DDR5	8GB LPDDR4X	8GB DDR4
Storage	1x NVMe + 1x SATA	microSD + NVMe (via HAT)	1x SATA
Network	2.5GbE (some models)	1GbE	1GbE
Idle Power	6–8W	5–7W	10–12W
Price	$150–$200	$80–$120	$120–$150

Core Principles

Principle 1: Right-Sizing Your Workload

The N100 is not a powerhouse. It has 4 cores and no hyperthreading. The key to happiness is running lightweight services in LXC containers or Docker, not heavy VMs. Stick to 1–2 VMs maximum, or use LXC for everything.

Principle 2: RAM Is the Bottleneck

Most N100 mini PCs have a single SODIMM slot, limiting you to 16GB DDR5. Some models (like the Minisforum UN100D) have dual slots for 32GB. Plan your services to fit within 12GB usable RAM (reserve 4GB for the host).

Typical RAM budget: - Proxmox host: 2GB - Pi-hole LXC: 0.5GB - AdGuard Home LXC: 0.5GB - Nextcloud LXC: 2GB - Jellyfin LXC: 1GB - Home Assistant LXC: 1GB - WireGuard LXC: 0.5GB - Reserve: 2GB - Total: ~9.5GB — fits comfortably in 16GB

Principle 3: Storage Strategy Matters

With only 1–2 drive slots, you must choose wisely: - Option A: Single 1TB NVMe for everything (simple, fast) - Option B: 256GB NVMe for OS + 1TB SATA SSD for data (separation, easy replacement) - Option C: External USB 3.2 2.5” HDD for bulk media (cheap, slow)

Applying This to Your Homelab

Homelab Setup Example

The “Essential Services” N100 Build: 1. Hardware: Beelink Mini S12 Pro (N100, 16GB DDR5, 500GB NVMe) 2. OS: Proxmox VE 8.2 3. Services: - LXC 101: Pi-hole (DNS + ad blocking) - LXC 102: AdGuard Home (backup DNS) - LXC 103: Nextcloud (files + calendar) - LXC 104: Jellyfin (media server) - LXC 105: Home Assistant (home automation) - LXC 106: WireGuard (VPN) 4. Power: 6–8W idle, 15–20W under load

Practical Steps

# Step 1: Install Proxmox on the N100
# Download ISO, flash to USB, install
# Use ext4 (not ZFS) since single drive + low RAM

# Step 2: Create LXCs from Debian 12 templates
# Download template first
pveam update
pveam download local debian-12-standard_12.2-1_amd64.tar.zst

# Create Pi-hole LXC
pct create 101 local:vztmpl/debian-12-standard_12.2-1_amd64.tar.zst \
  --hostname pihole --cores 1 --memory 512 --swap 512 \
  --net0 name=eth0,bridge=vmbr0,ip=dhcp --storage local-lvm --rootfs 8

# Step 3: Install Docker inside an LXC
pct create 102 local:vztmpl/debian-12-standard_12.2-1_amd64.tar.zst \
  --hostname docker --cores 2 --memory 4096 --swap 4096 \
  --net0 name=eth0,bridge=vmbr0,ip=dhcp --storage local-lvm --rootfs 32

# In the LXC console:
apt update && apt install -y docker.io docker-compose

# Step 4: Deploy services with docker-compose
mkdir -p /opt/services && cd /opt/services

# Example: Jellyfin
mkdir jellyfin && cd jellyfin
cat << 'EOF' > docker-compose.yml
services:
  jellyfin:

Common Mistakes to Avoid

Mistake 1: Buying a Single-Channel 8GB Model

Some N100 mini PCs ship with 8GB single-channel RAM. This is fine for 2–3 services, but you’ll run out of memory quickly. Always buy 16GB, or verify the SODIMM slot count.

Mistake 2: Enabling ZFS on a Single Drive

ZFS is amazing, but on a single NVMe with 16GB RAM, it causes performance issues and consumes RAM for ARC. Use ext4 or xfs for the host, and pass directories to containers.

Mistake 3: Running Windows VMs

The N100 can run a Windows VM, but it will consume 2–4 cores and 4–8GB RAM, leaving nothing for other services. If you need Windows, use a dedicated host or a cloud instance.

Conclusion

Summary

The Intel N100 mini PC is the best entry-level homelab server in 2026. It is cheap, silent, efficient, and capable of running 6–10 essential services in LXC containers. While it won’t replace a rack server for heavy virtualization, it is the perfect starting point for 80% of new homelabbers.

Low-Power Homelab Server Build Guide 2026: Under 15W Idle

2026-06-05T00:00:00+07:00

Reading time: ~15 minutes Audience: Homelabbers wanting 24/7 operation without high electricity bills

What Is a Low-Power Homelab Server?

A low-power homelab server is a virtualization or container host optimized for minimal electricity consumption. Unlike used rack servers that draw 100–200W, a low-power build targets 6–15W idle while still running multiple VMs, Docker containers, and services.

Why it matters: - Cost: A 15W server costs ~$15/year in electricity vs. $130+/year for a 120W rack server - Noise: Fanless or near-silent operation - Heat: Minimal impact on room temperature - 24/7 viability: Run without guilt or cost anxiety

Real-world power draw comparison:

Device	Idle Power	Load Power	Annual Cost (at $0.12/kWh)

Step-by-Step Instructions

Order the mini PC with at least 16GB RAM and NVMe storage.
Verify virtualization support in the product specs (Intel VT-x/VT-d or AMD-V/IOMMU).
Buy a smart plug (TP-Link Kasa EP25, ~$15) to monitor power consumption.

# After OS install, verify virtualization support
egrep -c '(vmx|svm)' /proc/cpuinfo
# Output > 0 = supported

Step 2: Install Proxmox VE (Lightweight Virtualization)

Objective

Install a Type-1 hypervisor for running multiple VMs and LXCs with minimal overhead.

Step-by-Step Instructions

Download Proxmox VE 8.2 ISO from proxmox.com.
Flash to USB with BalenaEtcher.
Boot the mini PC from USB and install Proxmox.
During install, choose:
Filesystem: ext4 (lower overhead than ZFS for single-drive setups)
Hostname: pve-lowpower
Network: static IP (e.g., 192.168.1.10/24)

# Post-install: disable high-availability services (not needed for single-node)
systemctl disable pve-ha-lrm pve-ha-crm corosync

# Disable enterprise repo (if no subscription)
sed -i 's/^deb/#deb/g' /etc/apt/sources.list.d/pve-enterprise.list

# Add no-subscription repo
echo "deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription" > /etc/apt/sources.list.d/pve-no-subscription.list
apt update && apt dist-upgrade -y

Step 3: CPU Power Management Tuning

Objective

Reduce idle power by enabling CPU power states and limiting peak frequency.

Step-by-Step Instructions

# Install powertop and cpupower
apt install -y linux-cpupower powertop

# Check current CPU governor
cpupower frequency-info

# Set powersave governor (Intel N100/N305)
cpupower frequency-set -g powersave

# Make it persistent
cat << 'EOF' > /etc/systemd/system/cpu-powersave.service
[Unit]
Description=Set CPU governor to powersave
After=multi-user.target

[Service]
Type=oneshot
ExecStart=/usr/bin/cpupower frequency-set -g powersave

[Install]
WantedBy=multi-user.target
EOF

systemctl enable --now cpu-powersave.service

# Tune with powertop (run for 60 seconds, then apply)
powertop --calibrate
powertop --auto-tune

# Make powertop auto-tune persistent
cat << 'EOF' > /etc/systemd/system/powertop.service
[Unit]
Description=Powertop auto-tune
After=multi-user.target

[Service]
Type=oneshot
ExecStart=/usr/sbin/powertop --auto-tune

[Install]
WantedBy=multi-user.target
EOF

systemctl enable --now powertop.service

Expected result: Idle power should drop 2–5W after tuning.

Step 4: Enable Hardware-Accelerated Transcoding (Optional)

Objective

If running Jellyfin or Plex, use Intel Quick Sync to reduce CPU load and power draw.

Step-by-Step Instructions

# Install Intel GPU drivers on Proxmox host
apt install -y intel-media-va-driver-non-free vainfo

# Verify Quick Sync
vainfo | grep -i "VAEntrypointVLD"

# In a Jellyfin LXC, mount the GPU
# Add to /etc/pve/lxc/XXX.conf:
# lxc.cgroup2.devices.allow: c 226:0 rwm
# lxc.cgroup2.devices.allow: c 226:128 rwm
# lxc.mount.entry: /dev/dri/renderD128 dev/dri/renderD128 none bind,optional,create=file

Step 5: Measure and Optimize Power Consumption

Objective

Establish a baseline and find remaining power drains.

Step-by-Step Instructions

# Install smartmontools to check disk power
apt install -y smartmontools

# Check disk power state
smartctl -i /dev/nvme0

# Enable SATA link power management (if using SATA SSD)
echo 'min_power' > /sys/class/scsi_host/host*/link_power_management_policy

# Disable HDMI output if headless (saves ~1W)
cat << 'EOF' > /etc/modprobe.d/blacklist-hdmi.conf
blacklist snd_hda_intel
EOF

# Check power consumption with powerstat (if available)
apt install -y powerstat
powerstat -d 0 -R 1 60

Measurement checklist: - [ ] Kill-a-Watt or smart plug showing < 15W idle - [ ] All VMs/LXCs running without CPU spikes - [ ] Network responding (ping 192.168.1.10) - [ ] Storage accessible (TrueNAS/Nextcloud functional)

Pro Tips

Tip 1: Use LXC Over VMs

LXC containers share the host kernel and use 10–20% less RAM and CPU than VMs. For Docker workloads, run a single LXC with Docker instead of multiple VMs.

Tip 2: Disable Unnecessary Services

On Proxmox single-node setups, disable: - pve-ha-lrm, pve-ha-crm, corosync (clustering) - pve-firewall (if using external firewall) - spiceproxy (if not using SPICE)

systemctl disable pve-ha-lrm pve-ha-crm corosync

Tip 3: Schedule Heavy Tasks

Run backups, ZFS scrubs, and antivirus scans during off-peak hours when solar power is available or time-of-use rates are cheaper.

Tip 4: Use a Single NVMe Drive

A single NVMe SSD uses 3–7W. Adding SATA SSDs or HDDs increases power by 2–5W each. For ultra-low power, stick to one 1TB NVMe.

Tip 5: Consider ARM for Extreme Low Power

If x86 compatibility isn’t needed, the Raspberry Pi 5 (8GB) or Orange Pi 5 Plus can run Docker at 5–7W. The trade-off is weaker x86 app support and no Proxmox.

Troubleshooting Common Issues

Problem 1: High Idle Power (25W+)

Cause: CPU governor set to performance, or GPU not sleeping.

Fix:

# Verify governor
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
# Should say "powersave"

# Check GPU power state
cat /sys/kernel/debug/dri/0/i915_frequency_info

Problem 2: Proxmox VM Performance Is Sluggish

Cause: N100 has only 4 cores/4 threads. Over-allocating vCPUs causes contention.

Fix: Limit VMs to 1–2 vCPUs and use LXC for lightweight services.

Problem 3: Network Drops After Power Saving

Cause: Aggressive PCIe power management.

Fix:

echo 'on' > /sys/class/net/eth0/device/power/control

Conclusion

Summary

A low-power homelab build around the Intel N100 or N305 can deliver real server capabilities at under 15W idle. With Proxmox VE, CPU power management tuning, and LXC containers, you can run 10–15 services for less than $15/year in electricity.

Next Steps

Install your first LXC container (Nextcloud, Jellyfin, or Pi-hole)
Set up automated backups with Proxmox Backup Server
Monitor power with a smart plug and log trends in Home Assistant

Mini PC Home Server 2025: The Ultimate Guide for Self-Hosters

2026-06-05T00:00:00+07:00

Reading time: ~16 minutes Audience: Anyone building a homelab on a mini PC

What Is a Mini PC Home Server?

What Exactly Is It?

A mini PC home server is a compact, low-power x86 computer that runs 24/7 to host services like Docker containers, file storage, media streaming, and network services. Unlike traditional rack servers or full-size desktops, mini PCs are silent, draw under 15W at idle, and fit on a bookshelf. In 2025, they have become the default choice for new homelab builds.

A Brief History

Mini PCs evolved from Intel’s NUC (Next Unit of Computing) line, introduced in 2013. Early NUCs were expensive and limited. In 2023–2024, Chinese manufacturers (Beelink, Minisforum, GMKtec) flooded the market with cheap, capable mini PCs based on Intel’s Alder Lake-N and AMD’s Ryzen U-series chips. The Intel N100 — a 6W quad-core processor — became the “sweet spot” for homelabbers, offering enough performance for 10–15 Docker containers at under $150.

Why It Matters Today

Electricity costs are rising. A full-size server drawing 100W+ costs $100–$200/year in power. A mini PC drawing 10W costs $15–$30/year. The performance gap has closed: modern mini PCs handle 4K transcoding, multiple VMs, and fast NVMe storage. For most homelabbers, a mini PC is the rational choice.

Why It Matters

Benefit 1: Extreme Power Efficiency

A mini PC with an Intel N100 idles at 4–6W and peaks at 15–20W. Under full load (Proxmox + 5 VMs), it draws 25–35W. Compare this to a Dell R720 rack server: 80–150W idle, 300W+ under load. Over 3 years, the power savings alone pay for the mini PC.

Benefit 2: Silent Operation

Mini PCs are fan-cooled but use small, low-RPM fans. Most produce under 25 dB at idle — quieter than a refrigerator. This makes them ideal for living rooms, offices, or apartments where rack servers are impossible.

Benefit 3: Low Cost of Entry

Component	Mini PC Build	Rack Server Build
CPU/Motherboard	Intel N100 (integrated)	$200+ used Xeon
RAM	16 GB DDR4 SODIMM	$100+ DDR4 ECC
Storage	512 GB NVMe	$100+ enterprise SSD
Case/PSU	Integrated	$200+ rack case + PSU
Total	$150–250	$600–1,000+

Core Principles

Principle 1: CPU Selection Is Critical

Explanation

Not all mini PC CPUs are created equal. For homelab use, you need: - Enough cores: 4+ cores for Proxmox + Docker. - QuickSync: Intel’s integrated GPU for hardware transcoding (Jellyfin, Immich). - Low TDP: Under 15W for 24/7 power efficiency. - x86 architecture: Avoid ARM mini PCs (e.g., Raspberry Pi) unless you enjoy compiling containers.

Example

The Intel N100 has 4 cores, 6W TDP, and Intel UHD Graphics with QuickSync. It can transcode 4–5 1080p streams in Jellyfin simultaneously. The AMD Ryzen 7 7840HS has 8 cores, 35W TDP, and RDNA3 graphics — overkill for most homelabs but excellent for GPU passthrough.

CPU	Cores	TDP	QuickSync	Best For
Intel N100	4	6W	✅	Entry-level Docker/Proxmox
Intel N200	4	6W	✅	Slightly faster N100
Intel N305	8	15W	✅	Proxmox with 4–5 VMs
Intel i3-N305	8	15W	✅	Same as N305, different branding
AMD Ryzen 7 7840HS	8	35W	❌ (no QuickSync)	GPU passthrough, high CPU load
AMD Ryzen 9 7940HS	8	35W	❌	Maximum performance mini PC

Principle 2: RAM and Storage Limits

Explanation

Mini PCs use SODIMM (laptop) RAM, typically limited to 16–64 GB depending on the model. Most N100-based mini PCs have a single RAM slot, limiting you to 16–32 GB. The N305 models often have dual SODIMM slots, supporting up to 64 GB.

Storage is usually 1–2 M.2 NVMe slots plus 1–2 SATA ports. For a homelab: - OS/Containers: 512 GB–1 TB NVMe (fast, low latency) - Media/Backups: 2.5” SATA SSD or external USB drive (cheap, large)

Example

A typical mini PC homelab setup: - OS: Proxmox VE on 256 GB NVMe - VM storage: 512 GB NVMe for VM disks - Media: 4 TB USB 3.0 external HDD for Jellyfin - Backups: 2 TB SATA SSD for restic/BorgBackup

Principle 3: Networking and Expandability

Explanation

Mini PCs typically have 2–2.5 GbE ports (Realtek or Intel). The Intel i226-V is preferred for Proxmox (better driver support). Some models (Minisforum MS-01) have 10GbE SFP+ or dual 2.5 GbE ports, ideal for NAS use.

USB ports are plentiful (4–6 USB 3.0). You can add: - USB-to-Ethernet adapters for extra NICs (Proxmox bonding) - USB storage for cheap expansion - USB serial adapters for UPS or console management

Example

The Minisforum MS-01 is a “prosumer” mini PC with: - Intel i9-13900H (14 cores) - 2 × 2.5 GbE (Intel i226) - 2 × 10GbE SFP+ - 3 × M.2 NVMe slots - 1 × U.2 NVMe bay

This is a mini PC that functions as a NAS, router, and virtualization host — all in 1.5 liters.

Applying This to Your Homelab

Homelab Setup Example

“The Budget Starter” — Intel N100 + 16 GB RAM

Services running: - Proxmox VE (host) - LXC: Pi-hole (DNS + ad blocking) - LXC: Portainer (Docker management) - VM: Docker host (Jellyfin, Nextcloud, Immich) - LXC: WireGuard VPN

Power draw: 8W idle, 18W under load. Monthly cost: ~$1.50 in electricity.

Practical Steps

# Step 1: Install Proxmox VE on the mini PC
# Download ISO from proxmox.com, flash to USB, install

# Step 2: Enable IOMMU for GPU passthrough (if needed)
nano /etc/default/grub
# Add: GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"
update-grub
reboot

# Step 3: Update Proxmox
apt update && apt dist-upgrade

# Step 4: Create an LXC container for Docker
pct create 9000 local:vztmpl/ubuntu-22.04-standard_22.04-1_amd64.tar.gz \
  -rootfs local-lvm:8 -memory 4096 -cores 2 -net0 name=eth0,bridge=vmbr0,ip=dhcp

# Step 5: Install Docker inside the LXC
pct enter 9000
apt install docker.io docker-compose -y

Common Mistakes to Avoid

Mistake 1: Buying a Mini PC Without QuickSync

If you plan to run Jellyfin, Immich, or Plex, you need Intel QuickSync for hardware transcoding. AMD mini PCs (Ryzen 5000/7000) do not have QuickSync. They can transcode via CPU, but it will peg your cores at 100% for 4K content.

Mistake 2: Using a Single RAM Slot Model for Proxmox

Some N100 mini PCs have only one SODIMM slot, limiting you to 16 GB. For Proxmox with 3+ VMs, 16 GB is tight. Buy a model with dual SODIMM slots (e.g., Minisforum UN100D, Beelink EQ12 Pro).

Mistake 3: Ignoring Realtek NIC Driver Issues

Realtek NICs (RTL8111H) work fine on Linux but can have issues with Proxmox SR-IOV or PCIe passthrough. If you plan advanced networking, choose a mini PC with Intel i225/i226 NICs.

Conclusion

Summary

Mini PCs have democratized homelabbing. For $150–250, you get a silent, low-power server capable of running Proxmox, Docker, media servers, and VPNs. The Intel N100 is the entry point; the N305 and Minisforum MS-01 are the upgrade path. The only reason to buy a rack server in 2025 is if you need 64+ GB RAM, multiple GPUs, or 10+ hard drives.

Next Steps

Measure your power budget: Use a Kill-A-Watt to see how much your current setup draws.
Pick a mini PC: Start with an Intel N100 model (Beelink EQ12, Minisforum UN100D).
Install Proxmox: Follow our Proxmox beginner guide.

Option C: Hybrid Approach (Best of Both Worlds)

Pros

A hybrid setup uses a mini PC as the primary 24/7 host and a rack server for heavy workloads or storage. This gives you the silence of a mini PC for everyday services and the power of a rack server when needed.

Example hybrid setup: - Mini PC (N100): Pi-hole, AdGuard, Home Assistant, VPN — 24/7 at 7W - Rack server (R720): TrueNAS, Plex, Proxmox cluster node — on-demand or scheduled

Cons

Higher total cost: Buying two machines
Complexity: Two systems to manage, patch, and backup
Network dependency: Services split across devices need reliable LAN

Best For

Users who want silent always-on services but also need heavy storage
Homelabbers with time-of-use electricity rates (rack server off during peak)
Those experimenting with clustering and high availability

Scenario 2: Garage or Basement with Power Outlets

Choose: Rack Server

You have space, power, and tolerance for noise. A used Dell R720 or HP DL380p gives you 64GB+ RAM, 8+ drive bays, and enterprise remote management for $200–$300.

Scenario 3: You Want to Learn VMware, Proxmox, or TrueNAS

Choose: Rack Server

Mini PCs lack the drive bays and RAM for serious ZFS or virtualization learning. You need a 2U server with 16+ SFF bays and 128GB RAM to explore enterprise storage and clustering.

Scenario 4: You Need 24/7 Services + Heavy Storage

Choose: Hybrid

Buy a mini PC ($180) for always-on services and a used rack server ($200) for TrueNAS. The mini PC sips power; the rack server sleeps when not needed or runs on a smart plug schedule.

Migration Path

Step 1: Start with a Mini PC

Buy a $150–$200 mini PC to learn Docker, Proxmox, and networking. Run Pi-hole, Nextcloud, and Jellyfin.

Step 2: Add a Rack Server for Storage

When you outgrow the mini PC’s 2–3 drive slots, buy a used 2U server. Move TrueNAS and Plex to the server. Keep the mini PC for lightweight services.

Step 3: Sell or Repurpose the Mini PC

If you move to a full rack environment, the mini PC becomes a portable travel lab, a backup DNS server, or a gift to a friend starting their homelab journey.

The Verdict

Budget	Recommendation	Setup
Under $200	Mini PC (N100)	Single device, Docker or Proxmox
$200–$400	Rack server (R720/DL380p)	Used enterprise, max bang for buck
$400–$600	Hybrid	Mini PC + rack server
$600+	Rack server (R730)	Modern DDR4, efficient, future-proof

Conclusion

Summary

Mini PCs are the best starting point for 80% of homelabbers. They’re silent, efficient, and capable. Rack servers are essential for storage-heavy, virtualization-heavy, or learning-heavy setups. The hybrid approach is the sweet spot for advanced users who want both.

Pi-hole Docker Compose Setup: Complete Homelab Guide

2026-06-05T00:00:00+07:00

Reading time: ~12 minutes Audience: Homelabbers wanting network-wide ad and tracker blocking

What Is Pi-hole?

Overview

Pi-hole is a DNS sinkhole that blocks ads, trackers, and malicious domains at the network level. By acting as your LAN’s DNS server, it intercepts queries to known ad domains and returns 0.0.0.0 — blocking ads on every device without installing browser extensions or apps.

Key Benefits

Benefit	Detail
Network-wide	One setup covers phones, TVs, IoT, and guests
Device-agnostic	Works on devices that can’t run ad blockers (smart TVs, consoles)
Low resource	Runs on a Raspberry Pi or in a Docker container
Privacy	Blocks trackers from Google, Facebook, Amazon, and analytics
Malware blocking	Filter lists include known malicious domains
Custom filtering	Add your own blacklists and whitelists
Statistics	See exactly which domains are queried and blocked

Pi-hole v6 (2025) changes: - Built-in web server (no Lighttpd dependency) - FTL v6 DNS engine (replaces dnsmasq) - TOML configuration format - Improved REST API

Prerequisites

Hardware Requirements

Any device running Docker (mini PC, Raspberry Pi, NAS, or VM)
512MB RAM minimum (1GB recommended)
2GB storage for logs and databases

Software Requirements

Docker Engine 24.x+ and Docker Compose v2+
Linux host (Debian 12, Ubuntu 22.04/24.04, or Proxmox LXC)
Router access to change DNS settings

Knowledge Prerequisites

Basic Docker and Linux commands
Router admin panel access
Understanding of DNS basics

Step 1: Create the Docker Compose File

Objective

Set up a reproducible Pi-hole deployment with persistent storage and proper network configuration.

Step-by-Step Instructions

Create a directory for Pi-hole:

mkdir -p ~/docker/pihole && cd ~/docker/pihole

Create docker-compose.yml:

services:
  pihole:
    container_name: pihole
    image: pihole/pihole:latest
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "8080:80/tcp"
    environment:
      - TZ=Asia/Singapore
      - WEBPASSWORD=ChangeMeStrong123!
      - FTLCONF_LOCAL_IPV4=192.168.1.10
      - PIHOLE_DNS_=1.1.1.1;1.0.0.1
      - FTLCONF_BLOCK_ICLOUD_PR=false
    volumes:
      - ./etc-pihole:/etc/pihole
      - ./etc-dnsmasq.d:/etc/dnsmasq.d
    cap_add:
      - NET_ADMIN
    restart: unless-stopped
    networks:
      - pihole-net

networks:
  pihole-net:
    driver: bridge

Create data directories:

mkdir -p etc-pihole etc-dnsmasq.d

Deploy:

docker compose up -d

Verify it’s running:

docker logs pihole | grep -i "finished"

Step 2: Configure Your Router to Use Pi-hole

Objective

Point all devices on your network to Pi-hole for DNS resolution.

Step-by-Step Instructions

Option A: Router DHCP DNS (Recommended) 1. Log into your router admin panel (usually 192.168.1.1 or 192.168.0.1) 2. Find DHCP Server or LAN Settings 3. Set Primary DNS to your Pi-hole IP (e.g., 192.168.1.10) 4. Set Secondary DNS to a backup (e.g., 1.1.1.1) or leave blank 5. Save and reboot the router

Option B: Pi-hole as DHCP Server If your router doesn’t allow custom DNS, disable its DHCP and let Pi-hole handle it: 1. In Pi-hole admin (Settings → DHCP), enable DHCP server 2. Set range: 192.168.1.100 to 192.168.1.200 3. Set router (gateway) to 192.168.1.1 4. Disable DHCP on your router 5. Renew leases on all devices (reconnect Wi-Fi or reboot)

Option C: Manual Per-Device On each device, set DNS to Pi-hole’s IP. Good for testing before network-wide rollout.

Step 3: Add Blocklists and Whitelists

Objective

Tune blocking to balance ad blocking with website functionality.

Step-by-Step Instructions

Log into Pi-hole admin at http://192.168.1.10:8080/admin
Default blocklists (enabled automatically):
StevenBlack’s unified hosts list
AdAway default blocklist
Add recommended blocklists (Group Management → Adlists):

https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts
https://adaway.org/hosts.txt
https://someonewhocares.org/hosts/zero/hosts
https://raw.githubusercontent.com/Spam404/lists/master/main-blacklist.txt
https://raw.githubusercontent.com/ShadowWhisperer/BlockLists/master/Lists/Tracking

Update gravity:

docker exec pihole pihole -g

Common whitelist entries (to avoid breaking sites):
clients4.google.com (Google Play/Android)
app-api.twitch.tv (Twitch login)
www.msftncsi.com (Windows connectivity check)

Step 4: Enable DNS-over-HTTPS (Optional but Recommended)

Objective

Encrypt DNS queries from Pi-hole to upstream resolvers for privacy.

Step-by-Step Instructions

Use Cloudflare’s cloudflared container as the upstream:

services:
  cloudflared:
    container_name: cloudflared
    image: cloudflare/cloudflared:latest
    command: proxy-dns
    environment:
      - TUNNEL_DNS_UPSTREAM=https://1.1.1.1/dns-query,https://1.0.0.1/dns-query
      - TUNNEL_DNS_PORT=5053
      - TUNNEL_DNS_ADDRESS=0.0.0.0
    restart: unless-stopped
    networks:
      - pihole-net

  pihole:
    container_name: pihole
    image: pihole/pihole:latest
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "8080:80/tcp"
    environment:
      - TZ=Asia/Singapore
      - WEBPASSWORD=ChangeMeStrong123!
      - PIHOLE_DNS_=cloudflared#5053
    volumes:
      - ./etc-pihole:/etc/pihole
      - ./etc-dnsmasq.d:/etc/dnsmasq.d
    cap_add:
      - NET_ADMIN
    restart: unless-stopped
    networks:
      - pihole-net
    depends_on:
      - cloudflared

networks:
  pihole-net:
    driver: bridge

Pro Tips

Tip 1: Use a MAC Address Reservation

Assign Pi-hole a static IP in your router’s DHCP reservations. If the IP changes, your entire network loses DNS.

Tip 2: Keep a Backup DNS

Set a secondary DNS (e.g., 1.1.1.1) on your router. If Pi-hole goes down, devices can still resolve. The trade-off is that some ads slip through during the outage.

Tip 3: Schedule Gravity Updates

# Add to crontab (docker host)
0 3 * * 0 cd ~/docker/pihole && docker exec pihole pihole -g

Tip 4: Monitor Block Percentage

A healthy Pi-hole blocks 10–30% of queries. If it’s under 5%, your blocklists are too conservative. If it’s over 50%, you’re probably breaking websites.

Troubleshooting Common Issues

Problem 1: “DNS Resolution Not Working”

Cause: Router not pointing to Pi-hole, or Pi-hole container not running.

Fix:

# Check if Pi-hole is running
docker ps | grep pihole

# Test DNS directly
nslookup google.com 192.168.1.10

# Check Pi-hole logs
docker logs pihole

Problem 2: “Some Websites Won’t Load”

Cause: Overly aggressive blocklist.

Fix: 1. Check Pi-hole Query Log for blocked domains 2. Whitelist the domain blocking the site 3. Use the pihole -t command to tail logs in real time

Problem 3: “Container Won’t Start — Port 53 in Use”

Cause: systemd-resolved or another DNS service is using port 53.

Fix:

# On Debian/Ubuntu, disable systemd-resolved
systemctl stop systemd-resolved
systemctl disable systemd-resolved
rm /etc/resolv.conf
ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf

Conclusion

Summary

Pi-hole in Docker Compose is the easiest way to deploy network-wide ad blocking. With a single docker-compose.yml file, you can block ads on every device in your home, improve privacy, and reduce bandwidth usage.

Next Steps

Add Unbound for recursive DNS without third-party resolvers
Set up AdGuard Home as a backup DNS
Monitor your network with Grafana and Prometheus

    volumes:
      - /:/rootfs:ro
      - /var/run:/var/run:ro
      - /sys:/sys:ro
      - /var/lib/docker:/var/lib/docker:ro
      - /dev/disk:/dev/disk:ro
    networks:
      - monitoring

volumes:
  prometheus_data:
  grafana_data:

Create prometheus.yml:

global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['localhost:9090']

  - job_name: 'cadvisor'
    static_configs:
      - targets: ['cadvisor:8080']

Deploy the stack in Portainer. Access Grafana at https://grafana.yourdomain.com.

Step 5: Add a Database Stack

Objective

Deploy PostgreSQL and Redis as reusable backing services for apps like Nextcloud, Immich, and Authelia.

Step-by-Step Instructions

Create a database stack in Portainer:

version: "3.8"

networks:
  backend:
    driver: bridge

services:
  postgres:
    image: postgres:16-alpine
    container_name: postgres
    restart: always
    environment:
      - POSTGRES_USER=admin
      - POSTGRES_PASSWORD=changeme-strong-password
      - POSTGRES_DB=postgres
    volumes:
      - postgres_data:/var/lib/postgresql/data
    networks:
      - backend
    ports:
      - "5432:5432"

  redis:
    image: redis:7-alpine
    container_name: redis
    restart: always
    networks:
      - backend
    volumes:
      - redis_data:/data
    ports:
      - "6379:6379"

volumes:
  postgres_data:
  redis_data:

Security note: Do not expose PostgreSQL and Redis to the internet. Use the backend network for internal communication only. If you must expose ports, restrict them with UFW or iptables.

Pro Tips

Tip 1: Use Portainer’s Environment Variables

Store secrets in Portainer’s Environment Variables section when creating a stack. This keeps passwords out of your Git repository.

Tip 2: Enable Stack GitOps

Portainer can poll a Git repository for docker-compose.yml changes and auto-deploy. This turns your homelab into a GitOps workflow: 1. Push a new Compose file to GitHub. 2. Portainer detects the change and redeploys.

Tip 3: Use Agent Mode for Remote Hosts

If you have multiple homelab servers, install the Portainer Agent on each:

docker run -d \
  -p 9001:9001 \
  --name portainer_agent \
  --restart=always \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /var/lib/docker/volumes:/var/lib/docker/volumes \
  portainer/agent:latest

Then add the agent endpoint in your main Portainer UI.

Tip 4: Backup Portainer Data

Portainer’s database is in its named volume. Back it up with:

docker run --rm -v portainer_data:/data -v $(pwd):/backup alpine \
  tar czf /backup/portainer-backup.tar.gz -C /data .

Troubleshooting Common Issues

Problem 1: Portainer Shows “Unable to Retrieve Containers”

Cause: The Docker socket is not mounted or Portainer lacks permissions. Fix:

docker stop portainer
docker rm portainer
docker run -d ... -v /var/run/docker.sock:/var/run/docker.sock ...

Problem 2: Traefik Not Generating Certificates

Cause: Port 80 is not reachable from the internet, or the DNS record is wrong. Fix: Ensure your router forwards port 80 and 443 to the Docker host. Verify DNS with dig yourdomain.com.

Problem 3: Stack Deploy Fails with “Network Not Found”

Cause: The stack references an external network (e.g., proxy) that does not exist. Fix: Create the network first:

docker network create proxy

Or set external: false in the Compose file.

Conclusion

Summary

Portainer transforms Docker from a CLI-only tool into a visual platform. With a single UI, you can manage reverse proxies, monitoring, databases, and dozens of apps. The stack-based deployment model keeps your homelab organized, reproducible, and version-controlled.

Next Steps

Add apps: Deploy Nextcloud, Jellyfin, Immich, and Pi-hole as separate stacks.
Set up HTTPS: Ensure every public service has a valid Let’s Encrypt certificate via Traefik.
Monitor: Use the Grafana stack to track CPU, memory, and container health.
Automate: Enable GitOps or Watchtower for automatic image updates.

System-wide view: CPU, memory, disk I/O, network, processes, and logs in one place
VM management: Create and manage KVM/QEMU VMs via libvirt integration
Storage management: Format, mount, RAID, and LVM management via web UI
Network management: Configure network interfaces, firewall zones, and bridging
User management: Create, edit, and manage Linux users and groups
Service control: Start, stop, and enable systemd services
Terminal access: Built-in web terminal with root access
Podman support: Native Podman container management (rootless containers)
SELinux troubleshooting: Visual audit logs and policy adjustments
Low overhead: Runs as a systemd service with minimal resource usage
Pre-installed: Included by default in Fedora, RHEL, CentOS Stream, and Ubuntu Server

Cons

Basic container management: No Compose support, no app templates, no registry browser
No multi-node clustering: Each server is managed individually
No RBAC: Single-user or shared sudo access only
No backup tools: No built-in container config export/import
Limited Docker support: Primarily targets Podman; Docker support is secondary
No stack management: Can’t define and deploy multi-container apps declaratively

Best For

Full Linux server administration (not just containers)
Users running KVM VMs alongside Docker
Red Hat/Fedora/CentOS ecosystems
Users who prefer Podman over Docker
System administrators learning Linux tools

Pricing

Edition	Cost	Features
Cockpit	Free (included in most distros)	Full feature set
Cockpit Client	Free	Connect to remote servers via SSH

Option C: Use Both (Best for Advanced Homelabs)

Pros

Portainer and Cockpit are complementary. Run Cockpit for system-level tasks (storage, networking, VMs, updates) and Portainer for container-level tasks (deploying apps, managing stacks, browsing logs).

Example workflow: 1. Cockpit: Create a new ZFS pool or format a disk 2. Portainer: Deploy a Jellyfin container that mounts the new storage 3. Cockpit: Check system resource usage after deployment 4. Portainer: Update the container image when a new release drops

Cons

Two UIs to remember: Slightly more cognitive load
Two ports to expose: Portainer (9000/9443) and Cockpit (9090)
Potential overlap: Both show container stats; choose your source of truth

Best For

Advanced homelabs with both VMs and containers
Users who want the best tool for each job
Sysadmins who want system visibility + container management

Comparison Matrix

Task	Portainer	Cockpit	Winner
Deploy Nextcloud via Docker Compose	★★★★★	★★☆☆☆	Portainer
Manage KVM VMs	★☆☆☆☆	★★★★★	Cockpit

Multi-node management	★★★★★	★★☆☆☆	Portainer
Manage systemd services	★☆☆☆☆	★★★★★	Cockpit
Rootless container security	★★☆☆☆	★★★★★	Cockpit

Which Should You Choose?

Scenario 1: Docker-Only Homelab

Choose: Portainer

If your homelab is 100% containers (no VMs), Portainer is the obvious choice. It has the best Compose support, app templates, and container management features.

Scenario 2: Mixed VMs and Containers

Choose: Cockpit + Portainer

Run both. Use Cockpit for Proxmox/KVM VMs and system administration. Use Portainer for Docker. They complement each other perfectly.

Scenario 3: Minimalist / Low-Resource Setup

Choose: Cockpit

If you run a single Raspberry Pi or N100 with 8GB RAM, Cockpit has lower overhead and covers both system and container basics without the bloat.

Scenario 4: Learning Linux Administration

Choose: Cockpit

Cockpit teaches you real Linux concepts (systemd, LVM, NetworkManager, firewall zones) that transfer directly to CLI skills. Portainer abstracts these away.

Migration Path

Step 1: Start with Portainer

If you’re new to Docker, install Portainer first. It makes learning containers much easier.

Step 2: Add Cockpit for System Tasks

When you need to manage storage, networking, or VMs, install Cockpit alongside Portainer.

Step 3: Graduate to CLI

Both tools are training wheels. As you learn, you’ll naturally move to docker compose, systemctl, nmcli, and virsh. The UIs remain useful for quick checks and visualizations.

The Verdict

Use Case	Recommendation
Docker-first homelab	Portainer
Mixed VMs + containers	Cockpit + Portainer
Learning Linux admin	Cockpit
Minimalist / low resource	Cockpit
Multi-node Docker clusters	Portainer Business
Red Hat / Fedora ecosystem	Cockpit (native integration)

Conclusion

Summary

Portainer is the king of Docker management. Cockpit is the king of Linux server administration. Most advanced homelabs benefit from running both. Beginners should start with Portainer for containers; system administrators should start with Cockpit for the full picture.

Prometheus Monitoring for Homelab: Metrics, Alerts, and Grafana

2026-06-05T00:00:00+07:00

Reading time: ~14 minutes Audience: Homelabbers wanting observability for their infrastructure

What Is Prometheus?

Overview

Prometheus is an open-source monitoring and alerting toolkit designed for reliability and scalability. It collects metrics from configured targets at given intervals, stores them in a time-series database, and allows querying via PromQL. It is the de facto standard for cloud-native monitoring and works perfectly for homelab observability.

Key Benefits

Benefit	Detail
Pull-based	Prometheus scrapes targets — no agent push needed
Time-series DB	Efficient storage of numeric metrics over time
PromQL	Powerful query language for alerts and dashboards
Exporters	Hundreds of community exporters for hardware, apps, and services
Alertmanager	Route alerts to email, Slack, Telegram, or webhooks
Service discovery	Auto-detect Docker containers, Kubernetes pods, or DNS entries
Native Grafana	First-class integration with Grafana dashboards

Prerequisites

Hardware Requirements

Any Docker host (mini PC, server, or VM)
1GB RAM for Prometheus + Alertmanager + Node Exporter
10GB+ storage for metrics retention (varies by scrape frequency and targets)

Step 2: Add Proxmox VE Exporter

Objective

Monitor Proxmox host metrics including VM/LXC status, storage, and node resources.

Step-by-Step Instructions

On Proxmox host, create a monitoring user:

pveum user add monitoring@pve --password "Change...3!"
pveum aclmod / -user monitoring@pve -role PVEAuditor

Add to prometheus.yml:

  - job_name: 'proxmox'
    static_configs:
      - targets: ['proxmox.example.com:9221']
    metrics_path: /pve
    params:
      module: [default]

Deploy Proxmox exporter container:

  proxmox-exporter:
    image: prompve/prometheus-pve-exporter:latest
    container_name: proxmox-exporter
    restart: unless-stopped
    environment:
      - PVE_USER=monitoring@pve
      - PVE_PASSWORD=Change...3!
      - PVE_HOST=https://192.168.1.10:8006
    ports:
      - "9221:9221"
    networks:
      - monitoring

Step 3: Configure Docker Daemon Metrics

Objective

Enable Docker’s built-in metrics endpoint for Prometheus.

Step-by-Step Instructions

Edit /etc/docker/daemon.json:

{
  "metrics-addr": "0.0.0.0:9323",
  "experimental": true
}

Restart Docker:

systemctl restart docker

Prometheus already scrapes this target via the docker job in prometheus.yml.

Pro Tips

Tip 1: Use Recording Rules for Complex Queries

Recording rules pre-compute expensive PromQL queries. Add them to rules/homelab.yml:

  - name: recording
    rules:
      - record: instance:cpu_usage
        expr: 100 - (avg by (instance) (irate(node_cpu_seconds_total{mode="idle"}[5m])) * 100)

Tip 2: Limit Retention for Storage

The default 30-day retention is usually enough for homelab. If storage is tight, reduce to 15 days:

command:
  - '--storage.tsdb.retention.time=15d'

Tip 3: Backup Prometheus Data

Prometheus data is in ./prometheus_data. Back it up with:

cd ~/docker/prometheus
tar czvf prometheus-backup-$(date +%F).tar.gz prometheus_data

Tip 4: Use Grafana for Visualization

Prometheus’s built-in UI is for debugging. Install Grafana for dashboards. See our Grafana Docker Compose guide for setup.

Troubleshooting Common Issues

Problem 1: “Targets Show as Down”

Cause: Network connectivity or container name resolution issues.

Fix:

# Test connectivity from Prometheus container
docker exec -it prometheus wget -qO- http://node-exporter:9100/metrics

# Check Prometheus logs
docker logs prometheus

Problem 2: “No Data in Queries”

Cause: Scrape interval too long, or target not configured.

Fix: - Reduce scrape_interval to 15s - Verify targets at http://your-server-ip:9090/targets - Check exporter is running: docker ps | grep exporter

Problem 3: “Alertmanager Not Sending Emails”

Cause: SMTP settings or authentication issues.

Fix: - Use an app-specific password (not your main password) for Gmail - Test SMTP with swaks or msmtp - Check Alertmanager logs: docker logs alertmanager

Conclusion

Summary

Prometheus gives you powerful observability over your homelab. With Node Exporter, cAdvisor, and the Proxmox exporter, you can monitor CPU, memory, disk, container, and VM metrics. Combined with Alertmanager, you’ll know immediately when something breaks.

How to Create Your First VM on Proxmox: A Step-by-Step Tutorial

2026-06-05T00:00:00+07:00

Reading time: ~12 minutes Audience: Proxmox beginners who have just installed the hypervisor

What Is a Proxmox VM?

Overview

A Virtual Machine (VM) on Proxmox is a full computer emulated in software. It has its own virtual CPU, RAM, disk, and network card. Unlike a container (LXC), a VM runs its own kernel and can run any operating system—Windows, Linux, BSD, or even macOS (with hacks). This tutorial walks you through creating an Ubuntu Server 24.04 LTS VM, the standard starting point for most homelab services.

Key Benefits

Isolation: A crashed VM does not affect the host or other VMs.
Snapshots: Freeze the entire VM state before updates. Roll back in seconds.
Hardware flexibility: Add or remove RAM, CPU cores, and disks without opening a case.
Migration: Move a running VM to another Proxmox node (with shared storage).

Prerequisites

Hardware Requirements

Proxmox host installed (bare metal or nested)
At least 4 GB free RAM on the host
At least 20 GB free storage (local-lvm, ZFS, or NFS)

Software Requirements

Ubuntu Server 24.04 LTS ISO (download from ubuntu.com)
Proxmox web UI access (https://your-proxmox-ip:8006)

Knowledge Prerequisites

Basic understanding of IP addresses and subnetting
Comfort with a Linux terminal (SSH or web shell)

Step 1: Upload the Ubuntu ISO to Proxmox

Objective

Before you can install a VM, Proxmox needs access to the installation media. You upload the ISO to the node’s local storage.

Step-by-Step Instructions

Log in to the Proxmox web UI (https://<proxmox-ip>:8006).
Select your node in the left sidebar (e.g., pve).
Click local under the node, then the ISO Images tab.
Click Upload and select your Ubuntu Server 24.04 ISO file.
Wait for the upload to complete. The ISO will appear in the list.

Alternative (CLI):

# SSH into Proxmox
scp ubuntu-24.04-live-server-amd64.iso root@<proxmox-ip>:/var/lib/vz/template/iso/

Step 2: Create the VM

Objective

Create a new VM with 2 CPU cores, 4 GB RAM, and a 32 GB disk.

Step-by-Step Instructions

Click the Create VM button in the top right.
General Tab:
VM ID: 100 (or the next available ID)
Name: ubuntu-server-01
Start at boot: Unchecked (for now)
OS Tab:
Use CD/DVD disc image file: Select the Ubuntu ISO you uploaded.
Guest OS Type: Linux
Version: 6.x - 2.6 Kernel (or Ubuntu 24.04 if available)
System Tab:
Machine: q35 (modern, supports PCIe passthrough)
BIOS: SeaBIOS (default) or OVMF for UEFI. For beginners, use SeaBIOS.
Add EFI Disk: Not needed for SeaBIOS.
QEMU Agent: Check Use QEMU Agent (enables guest reporting and shutdown from host).
Disks Tab:
Bus/Device: SCSI (default)
Storage: local-lvm (or your ZFS pool)
Disk size: 32 GB
Cache: Write back (default)
Discard: Check (helps with thin provisioning on SSDs)
CPU Tab:
Sockets: 1
Cores: 2
Type: host (passes host CPU features for best performance)
Memory Tab:
Memory: 4096 MB (4 GB)
Ballooning: Unchecked (for beginners, keep it simple)
Network Tab:
Bridge: vmbr0 (default LAN bridge)
VLAN Tag: Leave blank (or set if you use VLANs)
Firewall: Checked (Proxmox firewall rules will apply)
Confirm Tab: Review the summary. Click Finish.

The VM will appear in the left sidebar.

Step 3: Install Ubuntu Server

Objective

Boot the VM from the ISO and install Ubuntu Server.

Step-by-Step Instructions

Select the VM (ubuntu-server-01) and click Start.
Click Console to open the VNC window.
The VM will boot from the ISO. Select Try or Install Ubuntu Server.
Language: English
Keyboard layout: US (or your layout)
Network: The VM will get an IP from your LAN DHCP (e.g., 192.168.1.101). Note this IP.
Proxy: Leave blank (unless you have a corporate proxy)
Mirror: Default (Ubuntu archive)
Storage: Guided - use entire disk. Select the 32 GB virtual disk. Confirm.
Profile:
- Your name: Homelab Admin
- Server name: ubuntu-01
- Username: admin
- Password: Choose a strong password. Confirm it.
SSH: Check Install OpenSSH server. This is critical for remote management.
Featured Server Snaps: Skip for now (we will install Docker later).
The installer will partition, copy files, and install the kernel. This takes 5–10 minutes.
When finished, select Reboot Now. The VM will restart.

Important: After the first reboot, the VM will try to boot from the ISO again. In the Proxmox web UI, go to Hardware → CD/DVD Drive and click Remove or change it to Do not use any media. Then restart the VM.

Step 4: Configure the VM and Install QEMU Guest Agent

Objective

Ensure the VM reports its IP to Proxmox and can be shut down gracefully.

Step-by-Step Instructions

In the VM console, log in with the username and password you created.
Check the IP: bash ip addr show Look for eth0 or ens18 with an IP like 192.168.1.101.
Install QEMU Guest Agent: bash sudo apt update && sudo apt install qemu-guest-agent -y sudo systemctl enable qemu-guest-agent sudo systemctl start qemu-guest-agent
In the Proxmox web UI, the VM’s Summary tab should now show the IP address under “IPs.”
Test a graceful shutdown:
In Proxmox, right-click the VM → Shutdown.
The VM should power off cleanly within 10 seconds.

Step 5: Create a Cloud-Init Template (Advanced but Recommended)

Objective

Cloud-init lets you clone VMs with pre-configured hostnames, SSH keys, and IPs. This is how production Proxmox users deploy VMs.

Step-by-Step Instructions

Download the cloud image (instead of the ISO): bash cd /var/lib/vz/template/iso/ wget https://cloud-images.ubuntu.com/noble/current/noble-server-cloudimg-amd64.img
Create a new VM (ID 9000, name ubuntu-cloud-template) with no disk.
Import the image as a disk: bash qm importdisk 9000 noble-server-cloudimg-amd64.img local-lvm
In the VM hardware, attach the imported disk as SCSI.
Add a CloudInit drive (CD-ROM) in the hardware list.
In the Cloud-Init tab of the VM:
Set User: admin
Set Password: (or better, add an SSH public key)
Set IP Config: ip=192.168.1.0/24,gw=192.168.1.1 (use DHCP for beginners)
Convert the VM to a template: bash qm template 9000
Clone the template to create new VMs in seconds: bash qm clone 9000 101 --name ubuntu-web --full qm clone 9000 102 --name ubuntu-db --full

Pro Tips

Tip 1: Use Snapshots Before Major Changes

Before you run apt upgrade or install a risky app, take a snapshot:

In Proxmox, select the VM → Snapshots → Take Snapshot. Name it “pre-upgrade.”
If something breaks, right-click the snapshot → Rollback.

Tip 2: Reserve RAM for the Host

Never allocate 100% of host RAM to VMs. Proxmox needs 2–4 GB for itself, ZFS ARC, and overhead. If your host has 32 GB, cap VM allocations at 28 GB.

Tip 3: Enable Firewall Rules

Go to Datacenter → Firewall and enable the host firewall. Then, in each VM’s Firewall tab, add rules: - Allow SSH (port 22) from your LAN subnet. - Block everything else by default.

This adds a layer of protection even if the VM’s OS firewall is misconfigured.

Tip 4: Use Spice for Better Console Performance

VNC is slow for video. If you need to interact with a desktop VM, install spice-vdagent and use the SPICE console instead of VNC.

Troubleshooting Common Issues

Problem 1: “No Boot Device Found”

Cause: The ISO is still mounted, or the disk boot order is wrong.

Fix: - Go to Hardware → CD/DVD Drive and remove the ISO. - Go to Options → Boot Order and ensure the disk is first. - Restart the VM.

Problem 2: VM Gets No IP Address

Cause: The network bridge vmbr0 is not connected to a LAN with DHCP, or the VM’s NIC is disconnected.

Fix: - Check that vmbr0 on the Proxmox host has a valid IP. - In the VM hardware, ensure the network adapter is connected (checkbox). - Try setting a static IP in the VM if your LAN has no DHCP.

Problem 3: QEMU Guest Agent Does Not Show IP

Cause: The agent is not installed, or the VM was created without “QEMU Agent” checked.

Fix: - Install qemu-guest-agent inside the VM. - Shut down the VM, go to Hardware → Options, and ensure QEMU Agent is enabled. - Start the VM and wait 30 seconds.

Conclusion

Summary

You have created your first VM on Proxmox, installed Ubuntu Server, and configured QEMU Guest Agent. This is the foundation of your homelab. From here, you can clone VMs, take snapshots, and deploy Docker inside the VM for application hosting.

Proxmox vs VirtualBox for Beginners: Which One Wins for Your Homelab?

2026-06-05T00:00:00+07:00

Reading time: ~11 minutes Audience: Beginners choosing their first homelab hypervisor

The Proxmox vs VirtualBox Dilemma

Overview

VirtualBox is the familiar desktop hypervisor you probably used in school or work. Proxmox VE is a Linux-based, open-source enterprise hypervisor that runs headless on bare metal. If you want to turn an old PC into a 24/7 server, the choice between them defines your entire workflow: desktop convenience vs. server-grade power.

Key Differences at a Glance

Feature	Proxmox VE	VirtualBox
Type	Bare-metal (Type 1) hypervisor	Hosted (Type 2) hypervisor
OS	Dedicated Debian-based appliance	Runs on Windows, macOS, Linux
GUI	Web-based (no monitor needed)	Desktop GUI (needs monitor)
VMs + Containers	KVM VMs + LXC containers	KVM VMs only
Clustering	Native HA clustering	None
Live Migration	Yes (shared storage)	No
Open Source	Fully open source (AGPL)	Free for personal use (proprietary)
Learning Curve	Steeper	Gentle
Best For	24/7 servers, multi-VM labs	Quick testing, desktop sandboxing

Option A: Proxmox VE

Pros

Bare-metal performance: Runs directly on hardware; no host OS overhead.
Web UI: Manage from any device on your network. No monitor, keyboard, or mouse needed after install.
LXC containers: Run lightweight Linux containers alongside full VMs. A 512 MB container can host a whole web stack.
ZFS integration: Built-in ZFS support with snapshots, compression, and RAID-Z.
Backup & restore: Native vzdump backups, scheduled without third-party tools.
Free forever: No license fees for the community edition; enterprise support is optional.

Cons

Installs to disk: You must wipe the drive or dedicate a machine to it.
Command-line required: Some advanced tasks (GPU passthrough, PCI binding) require editing /etc/pve or GRUB configs.
Networking complexity: Linux bridges, VLANs, and bond configuration can overwhelm beginners.
No desktop GUI: You cannot run a local desktop on the Proxmox host (without nesting, which is discouraged).

Best For

Users with a dedicated spare machine, mini PC, or rack server.
Anyone who wants to run services 24/7 (Plex, Nextcloud, Pi-hole, etc.).
Homelabbers who want to learn enterprise virtualization (KVM, clustering, Ceph).

Pricing

Free (community edition, no subscription).
Enterprise subscription: ~$110/year per CPU socket (optional, adds support repo).

Option B: VirtualBox

Pros

Instant setup: Install like any desktop app. Create a VM in minutes.
Guest Additions: Seamless mouse, shared clipboard, and dynamic resolution for desktop VMs.
Snapshot tree: Visual snapshot branching (great for testing malware or risky updates).
Cross-platform: Run Windows VMs on macOS or Linux VMs on Windows.
USB passthrough: Simple, reliable USB device filtering for dongles or peripherals.
Large community: Every Linux distro tutorial assumes VirtualBox.

Cons

Type 2 overhead: Your host OS (Windows, macOS) consumes RAM and CPU cycles.
Not for 24/7: Running a VM while you sleep means your desktop stays on, wasting power.
No containers: You cannot run LXC or Docker natively inside VirtualBox without nesting.
No remote management: You need a monitor or RDP to the host to manage VMs.
Headless mode is clunky: VBoxHeadless exists, but the experience is inferior to Proxmox’s web UI.

Best For

Quick testing, OS evaluation, or software development sandboxes.
Users who only have one computer and cannot dedicate hardware.
Beginners who want to learn Linux without repartitioning.

Pricing

Free for personal use (VirtualBox Extension Pack has a free personal-use license).
Commercial use requires a license from Oracle.

Option C: The Hybrid Path (VirtualBox → Proxmox)

Pros

Many users start with VirtualBox, then migrate to Proxmox once they have spare hardware.
VirtualBox .ova files can be imported into Proxmox with qm importovf.
This path lets you learn virtualization concepts with zero risk.

Cons

Migration takes time (network reconfiguration, disk conversion, driver updates).
Some VirtualBox-specific settings (Guest Additions) do not transfer.

Best For

Absolute beginners who want to test the waters before committing hardware.

Pricing

Free for both stages.

Comparison Matrix

Use Case	Proxmox	VirtualBox	Winner
24/7 home server	✅ Native	❌ Host must stay on	Proxmox
Quick Windows test	✅	✅ Easier	VirtualBox
Multi-VM lab (10+ VMs)	✅	❌ Host chokes	Proxmox
LXC containers	✅ Built-in	❌ Not supported	Proxmox
GPU passthrough	✅ Advanced	✅ Basic	Proxmox
Laptop user	❌ Needs bare metal	✅ Runs on host	VirtualBox
Learning enterprise IT	✅ iDRAC-like experience	❌ Desktop toy	Proxmox

Which Should You Choose?

Scenario 1: “I have one laptop and want to learn Linux.”

Choose VirtualBox. Install Ubuntu, Debian, or Fedora in a VM without touching your main drive. You can snapshot before updates and roll back instantly. When you are ready, buy a $150 mini PC and switch to Proxmox.

Scenario 2: “I have an old desktop and want a 24/7 NAS and media server.”

Choose Proxmox. Install Proxmox on the bare metal. Create a VM for TrueNAS (or a container for Samba), another VM for Jellyfin, and a container for Pi-hole. You get enterprise-grade reliability, and you can manage it from your phone.

Scenario 3: “I want to build a career in IT / DevOps.”

Choose Proxmox. VirtualBox will not teach you clustering, live migration, Ceph storage, or network bridges. Proxmox is a free stand-in for VMware vSphere and is highly respected on resumes.

Migration Path: VirtualBox to Proxmox

Step 1: Export Your VirtualBox VM

In VirtualBox, select the VM and choose File → Export Appliance. Save as an .ova file.

Step 2: Upload to Proxmox

Use SCP or the Proxmox web UI (Datacenter → Storage → Upload) to move the .ova to /var/lib/vz/template/iso/.

Step 3: Import into Proxmox

# On Proxmox shell
qm importovf 9000 /var/lib/vz/template/iso/myvm.ova local-lvm
# Adjust VM ID (9000) and storage name as needed

Step 4: Fix Networking

Proxmox uses Linux bridges (vmbr0). After import, change the VM’s network adapter from the VirtualBox “NAT” style to a Proxmox bridge. You may need to reinstall guest drivers if the OS was Windows.

The Verdict

Verdict	Recommendation
Best for beginners	VirtualBox (zero commitment)
Best for homelab	Proxmox (power, containers, remote)
Best long-term	Proxmox (scales from 1 node to 16)

Conclusion

Summary

VirtualBox is the gateway drug of virtualization. It is perfect for learning, testing, and dabbling. Proxmox is the serious tool for a self-hosted infrastructure. If you have dedicated hardware and want to run services 24/7, Proxmox is the clear winner. If you are on a laptop and just curious, start with VirtualBox and migrate later.

Which Should You Choose?

Scenario 1: “I want the cheapest reliable Wi-Fi and switching setup.”

Choose TP-Link Omada. An EAP610 + SG2008P + self-hosted controller costs under $200 and covers most apartments or small homes. The performance is nearly identical to UniFi for day-to-day use.

Scenario 2: “I want cameras, doorbells, and sensors integrated with my network.”

Choose Ubiquiti UniFi. UniFi Protect is the only integrated NVR in this comparison. The G4 Bullet and G4 Instant are excellent cameras, and the AI detection works locally.

Scenario 3: “I need 10 GbE and SFP+ for my NAS and server.”

Choose UniFi (or MikroTik). UniFi’s XG line (USW-Aggregation, USW-Pro-Aggregation) has more 10 GbE options. However, MikroTik CRS switches are cheaper if you don’t need centralized management.

Migration Path

Step 1: Inventory Existing Hardware

List your current APs, switches, and gateway. Check if they support standard 802.3af/at PoE. If they do, you can mix vendors during migration.

Step 2: Deploy the Controller

Omada:

# Docker Compose for Omada Controller
docker run -d \
  --name omada-controller \
  -p 8088:8088 -p 8043:8043 \
  -v omada-data:/opt/tplink/EAPController/data \
  mbentley/omada-controller:latest

UniFi:

# Docker Compose for UniFi Network Server
docker run -d \
  --name unifi-controller \
  -p 8443:8443 -p 8080:8080 \
  -v unifi-data:/unifi \
  jacobalberty/unifi:latest

Step 3: Adopt Devices

In both controllers, go to Devices → Adopt and follow the adoption process. Reset devices to factory default if they were previously managed by another controller.

The Verdict

Verdict	Recommendation
Best for pure networking on a budget	TP-Link Omada
Best for all-in-one ecosystem	Ubiquiti UniFi
Best for stability and conservative updates	TP-Link Omada
Best for community and third-party tools	Ubiquiti UniFi
Best for 10 GbE / SFP+	Ubiquiti UniFi (or MikroTik)

Conclusion

Summary

TP-Link Omada is the value champion for homelab networking. It delivers 90% of UniFi’s functionality at 60% of the cost. Ubiquiti UniFi wins if you want an integrated ecosystem with cameras, advanced analytics, and the largest community.

Best UPS for Homelab in 2026: A Curated Guide

2026-06-05T00:00:00+07:00

Reading time: ~12 minutes Audience: Homelab builders who want clean power and graceful shutdowns

Why a UPS for Your Homelab?

A UPS (Uninterruptible Power Supply) does two things: it filters dirty power (surges, brownouts) and keeps your servers running during outages long enough to shut down gracefully. A hard shutdown can corrupt ZFS pools, corrupt databases, and damage spinning disks. A UPS is not a luxury; it is the cheapest insurance you can buy for your data.

Evaluation Criteria

Criteria	Why It Matters
VA / Watt Rating	VA is apparent power; Watts is real power. Modern PSUs have PFC, so you need a UPS that matches the wattage, not just the VA.
Runtime	How long the UPS can power your load. At 50% load, most units give 5–15 minutes.
Topology	Line-interactive (common, good for homelab) vs. Online double-conversion (best, expensive).
Outlets	Ensure enough NEMA 5-15R outlets for your server, switch, router, and modem.
USB / Network Management	A USB or SNMP card lets the UPS signal the OS to shut down before battery depletion.
Expandability	Some APC units accept external battery packs (EBM) to extend runtime.
Noise	Tower UPS units are quieter than rackmount units. For apartments, choose a tower.

Pro Tips

Tip 1: Calculate Your Load Before Buying

Use a Kill-A-Watt meter or ipmitool / sensors to measure your homelab’s actual wattage. Add 20% headroom. If your load is 300 W, buy a 600 W (or higher) UPS.

# On Linux, estimate power for a mini PC
sudo apt install powertop
powertop
# Look for "The battery reports a discharge rate of..."

Tip 2: Use NUT for Automated Shutdown

NUT (Network UPS Tools) lets your Proxmox host or NAS monitor the UPS and shut down gracefully when battery is low.

# Install NUT on Proxmox
apt install nut
# Edit /etc/nut/ups.conf to add your UPS (usbhid-ups driver)
# Edit /etc/nut/upsmon.conf to set the shutdown threshold (e.g., 20% battery)
systemctl enable nut-client
systemctl start nut-client

Tip 3: Replace Batteries Every 3–5 Years

Sealed lead-acid (SLA) batteries degrade. Even if the UPS “works,” a 5-year-old battery may give only 2 minutes of runtime. Replace proactively.

Conclusion

Summary

For most homelabbers, the APC Back-UPS Pro BR1500G or the CyberPower CP1500PFCLCD is the sweet spot. They offer enough wattage for a mini PC or tower server, have USB monitoring, and support NUT. If you have a rack server, step up to the APC Smart-UPS SMT1500RM2U. For a single-node mini PC, the Eaton 5E650iUSB is a budget-friendly start.

Our Recommendation

Mini PC homelab (1 node): Eaton 5E650iUSB ($70) or CyberPower CP1500PFCLCD ($190)
Tower server / NAS (2–3 nodes): APC BR1500G ($200) or CyberPower CP1500PFCLCD ($190)

Pro Tips

Tip 1: Buy from eBay Sellers with Warranties

Look for eBay sellers offering 30-day DOA warranties. Enterprise gear is reliable, but a dead PSU or RAID battery can sour the experience. Top sellers: SaveMyServer, TheServerStore, ServerMonkey.

Tip 2: Flash Your RAID Controller to IT Mode

For ZFS (TrueNAS, Proxmox with Ceph), you want the HBA to pass drives directly to the OS. Flash Dell PERC H310/H710 or HP P420 to IT mode (or buy an LSI 9211-8i). This is critical for homelab storage.

Tip 3: Replace Thermal Paste

Servers from 2012–2016 have dried-out thermal paste. A $10 tube of Arctic MX-6 and 30 minutes of work can drop CPU temps by 10–20°C and reduce fan noise dramatically.

Tip 4: Get the Rails (But Check Your Rack)

R720/DL380p rails are ~29” deep. If you have a network cabinet (shorter depth), you’ll need a shelf. Always verify rack depth before buying rails.

Tip 5: Plan for Power Costs

A 120W idle server costs about $10–$15/month in electricity (at $0.12/kWh). Over 3 years, that’s $360–$540 in power. A mini PC at 15W costs $45–$65 over the same period. Factor this into your total cost of ownership.

Conclusion

Summary

For most homelabbers in 2026, the Dell R720 remains the best starting point due to its balance of price, performance, and community support. If you want a quieter, more modern build, the Dell R730 or Supermicro tower are excellent alternatives. The HP DL380p Gen8 is the budget king, and the Lenovo SR530 offers modern architecture at a reasonable price.

Our Recommendation

Budget	Recommendation	Why
Under $150	HP DL380p Gen8 barebones + single CPU	Cheapest entry to enterprise features
$150–$300	Dell R720 dual E5-2670, 64GB RAM	Best community support and iDRAC
$300–$500	Dell R730 dual E5-2680 v3, 64GB DDR4	Future-proofed with DDR4 and efficiency

VPS vs Homelab Server: Which One Wins for Your Self-Hosting?

2026-06-05T00:00:00+07:00

Reading time: ~11 minutes Audience: Self-hosters deciding between a cloud VPS and a home server

The VPS vs Homelab Server Dilemma

Overview

A VPS (Virtual Private Server) is a slice of a datacenter server you rent by the month. A homelab server is a physical machine sitting in your home. Both let you self-host apps, but they differ radically in cost, privacy, performance, and control. This guide breaks down the trade-offs so you can choose the right infrastructure for your goals.

Key Differences at a Glance

Feature	VPS (Cloud)	Homelab Server
Location	Remote datacenter	Your home or office
Hardware	Shared (oversubscribed)	Dedicated (yours alone)
Upfront cost	$0	$150–$2,000
Monthly cost	$5–$100+	$5–$30 (electricity)
Internet speed	1–10 Gbps symmetric	Depends on your ISP (usually asymmetric)
IP address	Static or dynamic (provider dependent)	Dynamic (unless you pay for static)
Privacy	Provider can inspect VMs	Physical control; no third-party access
Noise / heat	None	Yes (depends on hardware)
Scalability	Instant resize	Must buy new hardware
Learning value	Limited (managed infra)	High (networking, hardware, virtualization)

Option A: VPS (Virtual Private Server)

Pros

No hardware hassle: No buying, building, or maintaining a physical machine.
Datacenter connectivity: 1 Gbps+ uplink, DDoS protection, and redundant power.
Static IP: Most providers offer a static IPv4 address (essential for DNS and mail servers).
Global presence: Deploy in Tokyo, Frankfurt, or New York to reduce latency for users.
Snapshot backups: One-click disk snapshots stored off-site.
No noise / heat: Perfect for apartments or shared living spaces.

Cons

Recurring cost: A $10/month VPS costs $120/year. A $40/month VPS costs $480/year. Over 3 years, you could have bought a powerful mini PC.
Oversubscription: Many budget VPS providers oversell CPU and RAM. Your “2 core” VPS may share a physical core with 10 other users.
Privacy risk: The provider can snapshot your disk, monitor traffic, or comply with legal requests. You do not own the hardware.
Bandwidth caps: Cheap VPS plans often have 1–2 TB/month transfer limits. Exceeding them incurs fees.
No custom hardware: You cannot add a GPU, a 10GbE NIC, or a ZFS array.

Best For

Users who need a public-facing server with a static IP.
Hosting websites, mail servers, or VPNs that need 24/7 uptime and DDoS protection.
Short-term projects or testing where you do not want to buy hardware.
Users in regions with unreliable power or internet.

Pricing

Budget: $5–8/month (1 vCPU, 1 GB RAM, 25 GB SSD) — Hetzner CX11, Vultr HF, DigitalOcean Droplet.
Mid-range: $20–40/month (2–4 vCPU, 4–8 GB RAM, 80–160 GB SSD) — Linode, OVH, Hetzner CPX21.
High-end: $80–200/month (8+ vCPU, 32 GB RAM, dedicated CPU) — AWS EC2, Azure, Google Cloud.

Option B: Homelab Server

Pros

One-time cost: A $300 mini PC or used rack server runs for 5–7 years. No monthly bill.
Total control: You own the hardware, the disks, and the network. No provider terms of service restricting crypto nodes, Tor, or game servers.
No bandwidth limits: Use your home ISP’s data cap (usually 1– TB or unlimited). No provider throttling.
Custom hardware: Add GPUs for transcoding, 10GbE NICs for fast storage, or 20 TB of hard drives for a NAS.
Privacy: Your data never leaves your home. No third-party has root access.
Learning: You learn real sysadmin skills (BIOS, RAID, networking, UPS, power management).

Cons

Dynamic IP: Most residential ISPs rotate IPs. You need DDNS (e.g., DuckDNS, Cloudflare) or a reverse proxy VPS.
ISP restrictions: Some ISPs block port 80/443, forbid servers in the ToS, or use CGNAT (no inbound connections at all).
Power and cooling: A rack server uses 100–300W and generates heat. A mini PC is better (10–40W).
Hardware failure: If a disk dies, you replace it. No provider SLA.
Initial complexity: You must set up the network, firewall, and backups yourself.

Best For

Users who want to learn Linux, virtualization, and networking hands-on.
Media servers (Plex, Jellyfin) that need large local storage and hardware transcoding.
Privacy advocates who want total data sovereignty.
Users with a stable home internet connection and a spare room or closet.

Pricing

Mini PC: $150–400 (Beelink, Minisforum, Intel NUC)
Used rack server: $200–600 (Dell R720, HP DL380p)
Electricity: $3–25/month depending on hardware and local rates

Option C: The Hybrid Approach

Pros

Many advanced homelabbers use both: a homelab server for local storage and media, and a cheap VPS for public ingress (reverse proxy, mail, VPN).
You can use a VPS as a WireGuard “bounce” node to tunnel into your home network, bypassing CGNAT.
This gives you the best of both worlds: local performance and global reach.

Cons

Two systems to manage and patch.
Two sets of backup strategies.

Best For

Users who want public services but also local, high-performance storage.

Pricing

VPS: $3–5/month (for reverse proxy / tunnel)
Homelab server: $300 upfront + $5/month electricity

Comparison Matrix

Use Case	VPS	Homelab Server	Winner
Public website / blog	✅ Static IP, fast uplink	❌ Dynamic IP, ISP blocks	VPS
Plex / Jellyfin (4K)	❌ Storage too expensive	✅ Local storage + GPU	Homelab
Nextcloud (personal files)	❌ Bandwidth caps	✅ Unlimited, private	Homelab
Mail server	✅ Static IP, no blacklist	❌ Dynamic IP blacklisted	VPS
Learning Linux / DevOps	❌ Abstracted hardware	✅ Full stack experience	Homelab
DDoS protection needed	✅ Built-in	❌ None	VPS
GPU transcoding / AI	❌ Expensive or unavailable	✅ Add any GPU	Homelab
Running Tor / crypto node	❌ ToS violation	✅ No restrictions	Homelab

Which Should You Choose?

Scenario 1: “I want to host a blog and a mail server.”

Choose a VPS. You need a static IP and clean reputation for email deliverability. A $5–10/month VPS from Hetzner or Vultr is perfect.

Scenario 2: “I want a media server and personal NAS.”

Choose a homelab server. A mini PC or old desktop with a 4 TB drive can run Jellyfin, Sonarr, and Samba. No bandwidth limits, no monthly storage fees.

Scenario 3: “I have CGNAT and no static IP, but I want public access.”

Choose the hybrid approach. Buy a cheap VPS ($3/month) and run a WireGuard tunnel. Point your domain to the VPS. The VPS forwards traffic through the tunnel to your homelab. You get public access without changing your ISP.

Migration Path: VPS to Homelab

Step 1: Export VPS Data

On your VPS, backup your data to a portable format:

# Example: export a Nextcloud database and files
mysqldump -u root -p nextcloud > nextcloud.sql
tar czvf nextcloud-data.tar.gz /var/www/nextcloud/data

Download the backups via SCP or rsync:

scp user@vps-ip:/home/user/nextcloud-* .

Step 2: Set Up Homelab Hardware

Install Proxmox or Ubuntu Server on your local machine. Create a VM or LXC container for the app.

Step 3: Restore Data

# On the homelab server
mysql -u root -p nextcloud < nextcloud.sql
tar xzvf nextcloud-data.tar.gz -C /var/www/nextcloud/

Step 4: Update DNS

Point your domain’s A record from the VPS IP to your home IP (or the VPS tunnel IP if using the hybrid model).

The Verdict

Verdict	Recommendation
Best for beginners	VPS (no hardware, instant setup)
Best for learning	Homelab server (hands-on, full stack)
Best for media / storage	Homelab server (cheap storage, no caps)
Best for public services	VPS (static IP, DDoS protection)
Best overall value	Hybrid (VPS + homelab)

Conclusion

Summary

A VPS is rented convenience. A homelab server is owned power. If you want to host a public website or need a static IP, start with a VPS. If you want to learn, store files, or run media locally, build a homelab. The hybrid approach—a cheap VPS for ingress and a homelab for storage—is the sweet spot for advanced users.

Pro Tips

Tip 1: Use a Reverse Proxy for HTTPS

Expose Wazuh Dashboard through NGINX Proxy Manager with a valid SSL certificate:

https://wazuh.yourdomain.com → http://wazuh-dashboard:5601

Tip 2: Backup Wazuh Data

Back up the named volumes regularly:

cd ~/docker/wazuh
docker compose stop
tar czvf wazuh-backup-$(date +%F).tar.gz /var/lib/docker/volumes/wazuh-*
docker compose start

Tip 3: Reduce Resource Usage for Small Homelabs

If running on a mini PC with 8GB RAM, reduce Indexer memory:

environment:
  - "OPENSEARCH_JAVA_OPTS=-Xms512m -Xmx512m"

Tip 4: Integrate with TheHive or Shuffle

Send Wazuh alerts to TheHive (case management) or Shuffle (SOAR automation) for advanced incident response.

Troubleshooting Common Issues

Problem 1: “Indexer Fails to Start — vm.max_map_count”

Cause: Kernel parameter not set correctly.

Fix:

sysctl -w vm.max_map_count=262144
echo "vm.max_map_count=262144" >> /etc/sysctl.conf
# Restart the container
docker compose restart wazuh.indexer

Problem 2: “Agent Not Appearing in Dashboard”

Cause: Agent registration failed, or firewall blocking port 1514/1515.

Fix:

# Check agent registration on manager
docker exec wazuh-manager /var/ossec/bin/agent_control -l

# Check agent logs on the endpoint
tail -f /var/ossec/logs/ossec.log

Problem 3: “Dashboard Shows No Alerts”

Cause: Rules not loaded, or no agents reporting.

Fix: - Verify agents are active in Management → Agents - Check that the manager is receiving events: docker logs wazuh-manager - Restart manager: docker compose restart wazuh-manager

Conclusion

Summary

Wazuh is the most powerful free security platform for homelabs. With Docker Compose, you can deploy a full SIEM/XDR stack in minutes. Monitor file integrity, detect vulnerabilities, assess CIS compliance, and respond to threats — all from a single dashboard.

AdGuard Home Docker Setup: Network-Wide Ad Blocking for Your Homelab

2026-06-04T20:35:00+07:00

Reading time: ~14 minutes Audience: Homelab and self-hosting enthusiasts

What Is AdGuard Home?

Overview

AdGuard Home is a network-wide ad and tracker blocking DNS server. Like Pi-hole, it acts as a DNS sinkhole, but it offers a modern web interface, built-in DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) support, and parental controls out of the box. It is written in Go, lightweight, and actively maintained by the AdGuard team.

A Brief History

AdGuard Home was released in 2019 as an open-source alternative to Pi-hole and AdGuard’s own commercial DNS. It gained popularity for its polished UI, native HTTPS support, and aggressive filtering engine. By 2026, it has become the default recommendation for users who want a modern DNS sinkhole without the plugin ecosystem of Pi-hole.

Why Use AdGuard Home in Your Homelab?

Modern DNS Privacy

AdGuard Home supports DoH, DoT, and DNS-over-QUIC natively. This encrypts DNS queries between your network and the upstream resolver, preventing ISPs and middlemen from snooping on your browsing history.

Built-in Parental Controls

Block adult websites, enforce safe search, and set time limits per client. This is useful for family networks and guest Wi-Fi without requiring client-side software.

Fast, Lightweight Engine

AdGuard Home’s filtering engine is written in Go and is faster than Pi-hole’s FTL for large blocklists. It handles millions of queries per day on a Raspberry Pi without strain.

Installation

Prerequisites

Linux server or Raspberry Pi with Docker
Port 53 (TCP/UDP) and 3000 (web UI) available
A static IP or DHCP reservation for the AdGuard host

Method 1: Docker Compose

version: "3.8"

services:
  adguardhome:
    image: adguard/adguardhome:latest
    container_name: adguardhome
    restart: always
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "80:80/tcp"
      - "443:443/tcp"
      - "3000:3000/tcp"
      - "853:853/tcp"
    volumes:
      - ./workdir:/opt/adguardhome/work
      - ./confdir:/opt/adguardhome/conf
    cap_add:
      - NET_ADMIN

Deploy:

docker compose up -d

Complete the setup wizard at http://your-server:3000.

Method 2: Docker Run

docker run -d --name adguardhome \
  --restart=always \
  -p 53:53/tcp -p 53:53/udp \
  -p 80:80/tcp -p 443:443/tcp \
  -p 3000:3000/tcp -p 853:853/tcp \
  -v $(pwd)/workdir:/opt/adguardhome/work \
  -v $(pwd)/confdir:/opt/adguardhome/conf \
  --cap-add=NET_ADMIN \
  adguard/adguardhome:latest

Basic Setup and Configuration

Step 1: Configure Upstream DNS

In Settings → DNS settings, choose encrypted upstreams:

https://dns.cloudflare.com/dns-query (Cloudflare DoH)
tls://dns.quad9.net (Quad9 DoT)
https://dns.adguard-dns.com/dns-query (AdGuard DoH)

For maximum privacy, run a local Unbound recursive resolver and set 127.0.0.1:5335 as the upstream.

Step 2: Add Filter Lists

AdGuard Home ships with default lists. Add more in Filters → DNS blocklists:

StevenBlack hosts
AdGuard DNS filter
MalwareDomainList
NoCoin filter list

Step 3: Set Up Client-Specific Rules

In Client settings, add devices by MAC or IP and assign custom filtering rules. Block social media for kids, allow all traffic for the home server, and enforce safe search for guests.

Advanced Features

DNS Rebinding Protection

AdGuard Home blocks DNS rebinding attacks by default. This prevents malicious websites from resolving private IP ranges (e.g., 192.168.x.x) to attack your router or internal services.

HTTPS Encryption for the Web UI

AdGuard Home can generate a Let’s Encrypt certificate for its web interface. In Encryption settings, enable automatic HTTPS and redirect HTTP to HTTPS.

Statistics and Query Log

The dashboard shows query volume, blocked percentage, top queried domains, and top clients. The query log is searchable and exportable. Use this to identify misbehaving IoT devices or tune your blocklists.

Integrating with Your Homelab

Reverse Proxy

Place AdGuard Home behind Traefik or Nginx Proxy Manager:

labels:
  - "traefik.enable=true"
  - "traefik.http.routers.adguard.rule=Host(`dns.yourdomain.com`)"
  - "traefik.http.routers.adguard.tls.certresolver=letsencrypt"
  - "traefik.http.services.adguard.loadbalancer.server.port=80"

VPN Integration

Set your VPN’s DNS to AdGuard Home for ad blocking on mobile devices. In WireGuard, set DNS = 192.168.1.10 in the client config.

Migration from Pi-hole

AdGuard Home can import Pi-hole blocklists and custom rules. Export your Pi-hole whitelist and blacklist, then import them via Filters → Custom filtering rules. The statistics history will not transfer.

Alternatives to Consider

Tool	Best For	DoH/DoT	Parental Controls	UI
AdGuard Home	Modern DNS filtering	Yes	Yes	Excellent
Pi-hole	Community, plugins	Via Unbound	No	Functional
Technitium DNS	Full DNS server	Yes	No	Advanced
NextDNS	Cloud-based, no hardware	Yes	Yes	Excellent

Frequently Asked Questions

Can I run AdGuard Home and Pi-hole together?

Not recommended on the same host due to port 53 conflicts. Choose one. If you need both features, use AdGuard Home as the primary and forward specific queries to Pi-hole for custom plugins.

Does AdGuard Home block YouTube ads?

Partially. DNS-level blocking cannot block all YouTube ads because they are served from the same domains as content. Use a browser extension for complete YouTube ad blocking.

How do I update AdGuard Home?

docker pull adguard/adguardhome:latest
docker compose up -d

Conclusion

Summary

AdGuard Home is the modern successor to Pi-hole for users who want DNS privacy, parental controls, and a polished UI in a single package. With Docker, it deploys in minutes. With DoH/DoT, it protects your queries from ISP surveillance. For new homelabs, AdGuard Home is the recommended default DNS sinkhole.

Next Steps

Deploy AdGuard Home and set it as your router’s DNS
Enable DoH or DoT for encrypted upstream queries
Configure client-specific rules for family devices
Monitor query statistics and tune blocklists

The AdGuard Home vs Pi-hole Dilemma

Overview

DNS-level ad blocking is the most impactful single improvement you can make to your home network. It blocks ads, trackers, and malware domains before any device loads them—phones, smart TVs, IoT devices, and guests all benefit without per-device configuration.

The two dominant open-source solutions are Pi-hole (the veteran, Linux-first) and AdGuard Home (the modern alternative with a polished UI). Both are free, Docker-friendly, and actively maintained. The right choice depends on your feature priorities and technical comfort level.

Key Differences at a Glance

Feature	Pi-hole	AdGuard Home
First release	2015	2019
UI polish	Functional, classic	Modern, responsive
DoH/DoT upstreams	Via cloudflared/unbound	Built-in
DNS rewrites	Via Local DNS Records	Built-in, easier
Per-client filtering	Via groups	Built-in, simpler
Parental controls	No	Built-in (safe search)
Query log retention	Configurable	Configurable, faster search
Blocklist syntax	Hosts + adlists + regex	Hosts + adlists + regex + $important
Statistics	Detailed, raw	Visual, polished
Mobile app	No	Yes (remote management)
Community size	Massive (r/pihole)	Large (r/Adguard)

Option A: Pi-hole

Pros

Mature ecosystem: 10+ years of community blocklists, documentation, and troubleshooting guides. If you have a problem, someone has solved it.
Lightweight: Runs on a Raspberry Pi Zero 2 W with 512 MB RAM. In a container, it uses ~60 MB RAM and minimal CPU.
Flexible blocklists: Supports standard hosts files, adlists, wildcard blocking, and advanced regex. The community maintains blocklists for every niche (gaming, smart TV, TikTok, etc.).
Teleporter: Built-in backup/restore tool exports settings, blocklists, and local DNS records to a JSON file. Migration between instances is trivial.
Gravity DB: Custom SQLite-based blocklist compiler. Fast query resolution even with 5 million blocked domains.

Cons

UI is dated: The web interface works but looks like a 2015 admin panel. No dark mode (as of 2026 v5.x).
DoH/DoT requires extra setup: You need a separate cloudflared or unbound container to encrypt upstream DNS queries.
No native mobile app: Management is web-only. No push notifications for blocked queries.
Per-client rules are clunky: Group management exists but is not intuitive for non-technical users.

Best For

Raspberry Pi and low-resource deployments
Users who want maximum blocklist flexibility and community support
Headless or automated setups (Pi-hole has excellent CLI/API tools)

Pricing

Free (open source, GPLv2). Optional donations via Open Collective.

Option B: AdGuard Home

Pros

Modern UI: Dark mode, responsive design, and a query log that is actually searchable in real time. The dashboard is usable on a phone without pinching.
Built-in encryption: DoH, DoT, and DNS-over-QUIC upstreams are configurable in the web UI without extra containers. AdGuard Home can also act as a DoH/DoT server for your devices.
Per-client configuration: Assign different filtering rules, blocklists, and DNS rewrites to specific MAC addresses or IP ranges. Easy to set up kids’ devices with stricter filters.
Parental controls: Force safe search on Google, Bing, and YouTube. Block adult sites via a built-in category filter.
Query log performance: Uses a custom database engine that handles high query volumes without slowing down the web UI.
Mobile app: AdGuard Home Manager (Android/iOS) allows remote status checks, top client monitoring, and temporary disable.

Cons

Slightly heavier: Uses ~100–150 MB RAM vs Pi-hole’s ~60 MB. Still trivial on modern hardware.
Smaller blocklist ecosystem: Most Pi-hole lists work, but some syntax differences exist. The AdGuard Home community maintains AdGuard SDN filter and AdGuard DNS filter as defaults.
Fewer third-party integrations: Pi-hole has native Home Assistant integration, Pi-hole 5 API wrappers in every language, and extensive automation scripts. AdGuard Home’s API is good but less widely used.

Best For

Users who value UI/UX and mobile management
Families needing parental controls and per-client rules
Users who want encrypted DNS without extra containers

Pricing

Free (open source, GPLv3). AdGuard also sells commercial DNS and VPN services, but Home is fully free.

Option C: Block DNS Ads at the Router (Adblock) or Hosts File

Pros

Zero infrastructure: Some routers (OpenWrt, ASUSWRT-Merlin, pfSense) have ad-blocking packages built in.
Hosts file: Edit /etc/hosts on each device. No server needed.

Cons

Limited blocklists: Routers typically support smaller lists. Hosts files are painful to sync across devices.
No stats: You lose visibility into what is being blocked.
Harder to manage: Updating blocklists requires SSH or manual edits.

Best For

Temporary setups or testing before committing to Pi-hole/AdGuard Home
Travel routers or single-device use

Comparison Matrix

Criteria	Pi-hole	AdGuard Home	Router Adblock
Setup ease	Easy	Easy	Medium
UI quality	Functional	Excellent	Varies
Resource use	Very Low	Low	Low
DoH/DoT	Extra container	Built-in	Varies
Per-client rules	Groups	Easy	No
Parental controls	No	Built-in	No
Query log speed	Good	Excellent	No
Mobile app	No	Yes	No
Blocklist count	10,000+	5,000+	100+
Community size	Massive	Large	Small

Which Should You Choose?

Scenario 1: Raspberry Pi or Mini PC with 2 GB RAM

Choose Pi-hole. It is lighter, and the 10-year community knowledge base means every edge case is documented. Pair it with unbound for recursive DNS:

# Docker Compose: Pi-hole + Unbound
services:
  pihole:
    image: pihole/pihole:2024.07.0
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "80:80/tcp"
    environment:
      - PIHOLE_DNS_=unbound#5053
  unbound:
    image: mvance/unbound:latest
    ports:
      - "5053:53/tcp"
      - "5053:53/udp"

Scenario 2: Family Network with Kids and Guests

Choose AdGuard Home. The parental controls, per-client rules, and safe search enforcement are family-friendly. You can set different blocklists for the kids’ tablets vs your work laptop. The mobile app lets you temporarily disable blocking when a false positive breaks a site.

Scenario 3: You Want the “Best of Both”

Run both. Seriously. Some homelabbers run Pi-hole as the primary DNS (for its Gravity blocklist performance) and AdGuard Home as a secondary upstream with different filtering rules. Or use Pi-hole for the network and AdGuard Home on a separate VLAN for guests.

Migration Path

Pi-hole to AdGuard Home

Export Pi-hole settings via Teleporter (Settings → Teleporter)
In AdGuard Home, go to Settings → DNS Blocklists → Add blocklist
Import your Pi-hole adlists manually (AdGuard Home does not parse Pi-hole Teleporter files directly)
Re-create Local DNS Records as DNS rewrites
Re-create client groups as per-client settings
Point your router DHCP DNS to AdGuard Home

AdGuard Home to Pi-hole

Export settings from AdGuard Home (Settings → General → Export)
In Pi-hole, add your AdGuard blocklists as adlists
Add DNS rewrites as Local DNS Records
Re-create per-client settings as Group Management rules

The Verdict

Priority	Winner	Reason
Raw performance	Tie	Both resolve DNS in <5 ms on modern hardware
UI/UX	AdGuard Home	Modern, dark mode, mobile app
Community/docs	Pi-hole	10 years of Reddit threads, scripts, and guides
Low-resource	Pi-hole	~60 MB RAM vs ~120 MB
Family features	AdGuard Home	Parental controls, per-client rules, safe search
Encryption	AdGuard Home	Built-in DoH/DoT/DNS-over-QUIC
Blocklist flexibility	Pi-hole	Larger ecosystem, more regex support

Our recommendation: If you are a technical user running a headless lab, choose Pi-hole for its community and lightness. If you share your network with family or want a polished, app-friendly experience, choose AdGuard Home.

Conclusion

Summary

Both Pi-hole and AdGuard Home are excellent DNS ad blockers. Pi-hole wins on maturity and resource efficiency. AdGuard Home wins on modern UI, built-in encryption, and family features. The “best” tool is the one that fits your household’s technical culture.

Best Self-Hosted Software 2026: The Privacy-First Toolkit for Your Homelab

2026-06-04T20:35:00+07:00

Reading time: ~18 minutes Audience: Homelab and self-hosting enthusiasts

Overview

Self-hosting is the practice of running software on your own hardware instead of relying on third-party cloud services. In 2026, the self-hosted ecosystem is more mature than ever, with polished alternatives to Google, Microsoft, and Apple services. This guide presents the best self-hosted software across 10 categories, selected for stability, community support, and real-world usability.

Why Use Self-Hosted Software?

Data Sovereignty

Your data stays on your hardware. No terms-of-service changes, no account bans, and no AI training on your personal files.

Cost Control

A one-time hardware purchase replaces recurring subscriptions. A family of four can save $500+ annually by self-hosting cloud storage, photos, and password management.

Broadcom VMware Pricing Shock: Why Homelabbers Are Fleeing to Proxmox

2026-06-04T20:35:00+07:00

Reading time: ~15 minutes
Audience: Homelab builders, IT professionals, self-hosting enthusiasts

The Broadcom Acquisition: What Changed

November 2023: The Deal Closes

Broadcom completed its $61 billion acquisition of VMware on November 22, 2023. Within months, the company announced sweeping changes to VMware’s product portfolio, licensing model, and pricing structure. For homelabbers who relied on VMware ESXi free edition, the impact was immediate and devastating.

The Death of Free ESXi

On December 13, 2023, Broadcom announced the end of VMware vSphere Hypervisor (ESXi) free edition. The free version — which had been a staple of homelab environments for over a decade — was discontinued with no direct replacement. Key changes included:

Free ESXi eliminated: No new downloads, no new licenses
VMware Workstation/Fusion sold: Bought by KeySight, creating uncertainty
Product bundling: Former à-la-carte products forced into expensive bundles
Partner program overhaul: Thousands of VMware partners lost their status

Enterprise Price Increases

Product	Pre-Broadcom Price	Post-Broadcom Price	Increase
vSphere Foundation (per CPU)	~$1,200	~$4,500	275%
vSphere Essentials Kit	~$576/year	~$7,500/year	1200%
vCenter Server Std	~$8,000	~$35,000	340%
vSAN (per CPU)	~$2,500	Bundled only	N/A
NSX (per CPU)	~$2,000	Bundled only	N/A

Sources: Broadcom VMware pricing announcements, Reddit r/homelab community reports, The Register reporting

Why It Matters for Homelabbers

The ESXi Free Edition Was the Gateway Drug

For thousands of IT professionals, VMware ESXi free was the entry point into virtualization. It offered:

Full hypervisor functionality (with the 8-vCPU limit)
VMware vSphere Client for management
VMware Tools for guest optimization
Hardware compatibility list (HCL) for reliable builds

Without a free tier, the barrier to entry for learning enterprise virtualization skyrocketed.

The Homelab Community Exodus

Reddit r/homelab and r/vmware saw a massive spike in migration posts during Q1 2024. Common themes:

“What do I use instead of ESXi?” — 15+ daily posts at peak
“Proxmox vs XCP-ng?” — The new default debate
“How do I migrate my VMs?” — Technical how-to demand

Quarter	r/homelab “Proxmox” Mentions	r/homelab “ESXi” Mentions
Q3 2023	~200/month	~400/month
Q1 2024	~1,200/month	~600/month
Q3 2024	~2,000/month	~300/month

Estimates based on Reddit search trends and community observation

Proxmox: The Default Alternative

What Is Proxmox VE?

Proxmox Virtual Environment (VE) is an open-source server virtualization management platform. It combines:

KVM hypervisor for full virtualization
LXC containers for lightweight OS-level virtualization
Web-based management — no separate client needed
ZFS support built-in
Ceph integration for distributed storage
Clustering up to 32 nodes (free)

Why Proxmox Won the Homelab Market

Factor	Proxmox	ESXi Free (RIP)
Cost	Free (subscription optional)	$0 (discontinued)
Web UI	Built-in, responsive	vSphere Client required
Containers	LXC native	N/A
Storage	ZFS, Ceph, LVM, NFS	VMFS, NFS, iSCSI
Backup	Built-in (vzdump)	N/A (free)
API	REST API (full)	Limited (free)
Community	Very active, open-source	Corporate, shrinking

Proxmox Subscription Pricing (For Context)

Even Proxmox’s paid tiers are dramatically cheaper than VMware:

Subscription	CPUs	Price/Year	Support
Community (free)	Unlimited	$0	Forums only
Basic	2	~$95	Business hours
Standard	2	~$190	24/7
Premium	2	~$380	24/7 + phone

Compare to VMware vSphere Foundation at ~$4,500/CPU

Migration Path: ESXi to Proxmox

Step 1: Inventory Your VMs

# On ESXi host, list all VMs
vim-cmd vmsvc/getallvms

# Export VM configuration for documentation
vim-cmd vmsvc/getallvms > /tmp/vm-inventory.txt

Step 2: Export VM Disk Images

# Export each VM's disk to OVF/OVA format
# Use VMware vSphere Client or ovftool
ovftool vi://root@esxi-host.local/VM_Name /tmp/VM_Name.ova

Step 3: Import to Proxmox

# On Proxmox host, import the OVA
qm importovf 9000 /tmp/VM_Name.ova local-lvm

# Or import raw disk images
qm importdisk 9000 /tmp/VM_Name-disk1.vmdk local-lvm --format qcow2

Step 4: Reconfigure Networking

# Proxmox uses Linux bridges (vmbr0, vmbr1, etc.)
# Map your ESXi port groups to Proxmox bridges

# Example /etc/network/interfaces snippet
auto vmbr0
iface vmbr0 inet static
    address 192.168.1.10/24
    gateway 192.168.1.1
    bridge-ports enp1s0
    bridge-stp off
    bridge-fd 0

Step 5: Install Guest Agents

# For Linux VMs
apt install qemu-guest-agent
systemctl enable qemu-guest-agent

# For Windows VMs
# Download virtio-win ISO, install QEMU Guest Agent

Other ESXi Alternatives Worth Considering

XCP-ng + Xen Orchestra

Pros: Enterprise-grade, Xen heritage, commercial support available
Cons: Smaller community than Proxmox, steeper learning curve
Best for: Users who need Citrix XenApp/XenDesktop compatibility

TrueNAS SCALE (Virtualization)

Pros: ZFS storage + KVM in one platform, excellent NAS features
Cons: Newer virtualization stack, less mature than Proxmox
Best for: Storage-first homelabs wanting light virtualization

Hyper-V (Windows)

Pros: Free with Windows Server, PowerShell automation, RDP integration
Cons: Windows-only, less container support, licensing complexity
Best for: Windows-centric environments

Alternative	Type	Best For	Learning Curve
Proxmox VE	KVM + LXC	General homelab	Medium
XCP-ng	Xen	Enterprise features	High
TrueNAS SCALE	KVM + ZFS	Storage-first	Medium
Hyper-V	Type-1	Windows shops	Low
ESXi (paid)	Type-1	Corporate compliance	Medium

Common Migration Mistakes

Mistake 1: Trying to Run ESXi Without Updates

ESXi free is dead. Running unpatched ESXi is a security risk. Broadcom no longer releases free security patches. Migrate ASAP.

Mistake 2: Ignoring Hardware Compatibility

Proxmox has broader hardware support than VMware (no HCL required), but: - NICs: Intel i210/i225/i226 work best. Realtek NICs need extra drivers. - Storage controllers: LSI/Broadcom HBA cards (9211, 9300 series) are ideal. - GPU passthrough: Intel integrated graphics work well; NVIDIA requires extra steps.

Mistake 3: Overlooking Backup Strategy

Proxmox’s built-in vzdump is excellent. Set it up immediately:

# Enable Proxmox Backup Server or local backups
# In Proxmox Web UI: Datacenter > Backup > Add

# Or use CLI:
vzdump 9000 --mode snapshot --compress zstd --storage local-backup

Conclusion

Summary

Broadcom’s VMware acquisition destroyed the free ESXi ecosystem, raised enterprise prices by 300-1200%, and triggered the largest homelab migration in recent history. Proxmox VE has emerged as the default replacement, offering comparable functionality at zero cost with a vibrant open-source community.

Docker Compose Tutorial for Homelab: From Zero to Production Stacks

2026-06-04T20:35:00+07:00

Reading time: ~18 minutes Audience: Homelab and self-hosting enthusiasts

What Is Docker Compose?

Overview

Docker Compose is a declarative tool for defining and running multi-container Docker applications. Instead of typing long docker run commands for each container, you write a YAML file that describes your entire application stack — services, networks, volumes, and environment variables. A single command (docker compose up -d) creates everything. This makes your infrastructure reproducible, version-controlled, and easy to share.

Why It Matters for Homelabs

Most homelab applications require multiple containers: a web app, a database, a cache, and a reverse proxy. Managing these with raw Docker commands is error-prone. Compose turns this into a single file that you can store in Git, deploy on any machine, and update with confidence.

Why Learn Docker Compose?

Declarative Infrastructure

Your entire stack is defined in code. If your server dies, you can clone the repo, run docker compose up, and be back online in minutes. This is the foundation of modern infrastructure as code.

Easy Updates and Rollbacks

Update a service by changing the image tag in the Compose file and running docker compose up -d. If something breaks, revert the tag and redeploy. The old container is recreated automatically.

Service Discovery and Networking

Compose automatically creates a private network for your stack. Containers can reach each other by service name (e.g., http://db:5432). No manual IP management or port mapping required for internal communication.

Prerequisites

Hardware Requirements

Any Linux machine (mini PC, old laptop, VPS)
2 GB RAM minimum, 4 GB recommended
20 GB storage

Software Requirements

Docker Engine 20.10+
Docker Compose plugin v2.x
A text editor (nano, vim, or VS Code)

Knowledge Prerequisites

Basic Linux command line
Understanding of Docker images and containers
Familiarity with YAML indentation (spaces, not tabs)

Step 1: Install Docker Compose

Objective

Ensure the Docker Compose plugin is installed and working.

Step-by-Step Instructions

# Verify Docker Compose is installed
docker compose version
# Expected: Docker Compose version v2.x.x

# If missing, install it (Ubuntu/Debian)
sudo apt update
sudo apt install -y docker-compose-plugin

# Verify again
docker compose version

If you still have the legacy docker-compose (Python) binary, migrate to the plugin. The plugin is faster and supports the latest features.

Step 2: Write Your First Compose File

Objective

Create a simple stack with an Nginx web server.

Step-by-Step Instructions

Create a project directory:

mkdir -p ~/homelab-tutorial && cd ~/homelab-tutorial

Create docker-compose.yml:

version: "3.8"

services:
  web:
    image: nginx:alpine
    container_name: my-nginx
    restart: always
    ports:
      - "8080:80"
    volumes:
      - ./html:/usr/share/nginx/html:ro

Create a simple HTML file:

mkdir -p html
echo "<h1>Hello from Docker Compose!</h1>" > html/index.html

Deploy:

docker compose up -d

Verify:

curl http://localhost:8080
# Output: <h1>Hello from Docker Compose!</h1>

Step 3: Add a Database and Connect Services

Objective

Extend the stack with a MariaDB database and demonstrate service discovery.

Step-by-Step Instructions

Update docker-compose.yml:

version: "3.8"

services:
  web:
    image: nginx:alpine
    container_name: my-nginx
    restart: always
    ports:
      - "8080:80"
    volumes:
      - ./html:/usr/share/nginx/html:ro
    depends_on:
      - db

  db:
    image: mariadb:10.6
    container_name: my-mariadb
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=secret_root_pass
      - MYSQL_DATABASE=myapp
      - MYSQL_USER=myapp
      - MYSQL_PASSWORD=secret_app_pass
    volumes:
      - db_data:/var/lib/mysql

volumes:
  db_data:

Key observations: - The web service can reach the database at db:3306 (service name becomes hostname) - depends_on ensures db starts before web, but does not wait for it to be ready - db_data is a named volume managed by Docker; data persists across container recreations

Deploy the updated stack:

docker compose up -d

Step 4: Use Environment Variables and Secrets

Objective

Externalize configuration with a .env file.

Step-by-Step Instructions

Create .env:

MYSQL_ROOT_PASSWORD=super_secret_root
MYSQL_DATABASE=myapp
MYSQL_USER=myapp
MYSQL_PASSWORD=super_secret_app
NGINX_PORT=8080

Update docker-compose.yml:

version: "3.8"

services:
  web:
    image: nginx:alpine
    container_name: my-nginx
    restart: always
    ports:
      - "${NGINX_PORT}:80"
    volumes:
      - ./html:/usr/share/nginx/html:ro
    depends_on:
      - db

  db:
    image: mariadb:10.6
    container_name: my-mariadb
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
      - MYSQL_DATABASE=${MYSQL_DATABASE}
      - MYSQL_USER=${MYSQL_USER}
      - MYSQL_PASSWORD=${MYSQL_PASSWORD}
    volumes:
      - db_data:/var/lib/mysql

volumes:
  db_data:

Add .env to .gitignore:

echo ".env" >> .gitignore

Step 5: Add a Reverse Proxy and Custom Network

Objective

Deploy Traefik as a reverse proxy with automatic HTTPS and a custom bridge network.

Step-by-Step Instructions

version: "3.8"

networks:
  frontend:
    driver: bridge
  backend:
    driver: bridge

services:
  traefik:
    image: traefik:v3.0
    container_name: traefik
    restart: always
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./letsencrypt:/letsencrypt

Pro Tips

Tip 1: Use Profiles for Conditional Services

services:
  dev-tools:
    image: phpmyadmin
    profiles:
      - dev

Deploy with docker compose --profile dev up -d to include dev tools only when needed.

Tip 2: Health Checks for Reliability

services:
  db:
    image: mariadb:10.6
    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-h", "localhost"]
      interval: 10s
      timeout: 5s
      retries: 5

Tip 3: Resource Limits

services:
  web:
    deploy:
      resources:
        limits:
          cpus: '0.5'
          memory: 256M

Tip 4: Override Files for Environments

Create docker-compose.override.yml for local tweaks (not committed to production):

services:
  web:
    ports:
      - "8080:80"

Troubleshooting Common Issues

Problem 1: “port is already allocated”

# Find the conflicting process
sudo ss -tlnp | grep :80

# Kill it or change the host port in Compose

Problem 2: “Container unhealthy”

# Check the healthcheck definition
docker inspect <container> | jq '.[0].State.Health'

# Review logs
docker compose logs <service>

Problem 3: “Permission denied on volume”

# Check the user running inside the container
docker exec <container> id

# Fix host permissions
sudo chown -R 1000:1000 ./data

Reading time: ~18 minutes Audience: Homelab and self-hosting enthusiasts

What Is Docker Compose?

Overview

Docker Compose is a tool for defining and running multi-container Docker applications. With a single YAML file, you configure services, networks, and volumes. One command (docker compose up -d) brings the entire stack online. For homelab operators, Compose is the standard deployment method because it is declarative, version-controlled, and reproducible across machines.

Key Concepts

Services: Individual containers (e.g., nginx, db, app)
Networks: Isolated communication channels between services
Volumes: Persistent storage for container data
Environment Variables: Secrets and configuration passed at runtime
Profiles: Conditional service groups (e.g., dev, prod)

Prerequisites

Hardware Requirements

Any Linux server with Docker and Docker Compose installed
At least 2 GB RAM for small stacks, 8 GB+ for full monitoring suites

Software Requirements

Docker Engine 20.10+
Docker Compose plugin (v2.x)

In Pi-hole, set Custom DNS to 127.0.0.1#5335.

Pro Tips

Tip 1: Use .env Files for Secrets

Never commit secrets to your Compose file. Use a .env file:

DB_PASSWORD=supersecret
DOMAIN=yourdomain.com

And reference variables in Compose:

environment:
  - MYSQL_PASSWORD=${DB_PASSWORD}

Add .env to .gitignore.

Tip 2: Health Checks and Restart Policies

Add health checks to ensure services recover automatically:

healthcheck:
  test: ["CMD", "curl", "-f", "http://localhost:80"]
  interval: 30s
  timeout: 10s
  retries: 3
  start_period: 40s

Tip 3: Resource Limits

Prevent a runaway container from consuming all RAM:

deploy:
  resources:
    limits:
      cpus: '1.0'
      memory: 512M
    reservations:
      cpus: '0.25'
      memory: 128M

Tip 4: Named Volumes vs Bind Mounts

Named volumes: Managed by Docker, portable, best for databases
Bind mounts: Direct host filesystem mapping, best for config files and media

Troubleshooting Common Issues

Problem 1: Port Already in Use

# Find the process using the port
sudo ss -tlnp | grep :80

# Kill or reconfigure the conflicting service

Problem 2: Permission Denied on Bind Mounts

# Fix ownership
sudo chown -R 1000:1000 ./data

# Or use Docker user namespaces

Problem 3: Container Exits Immediately

# Check logs
docker compose logs <service_name>

# Inspect the container
docker inspect <container_name>

Conclusion

Summary

Docker Compose is the backbone of modern homelab infrastructure. It turns complex multi-service applications into declarative, reproducible configurations. The examples in this guide cover the most common patterns: reverse proxying, monitoring, cloud storage, and DNS filtering. With these templates, you can deploy a full homelab stack in minutes.

Docker Monitoring with Grafana and Prometheus: A Complete Homelab Guide

2026-06-04T20:35:00+07:00

Reading time: ~16 minutes Audience: Homelab and self-hosting enthusiasts

What Is Prometheus and Grafana?

Overview

Prometheus is an open-source monitoring and alerting toolkit designed for reliability and scalability. It scrapes metrics from endpoints (exporters) using HTTP pulls, stores them in a time-series database, and evaluates alerting rules. Grafana is a visualization platform that queries Prometheus (and other data sources) to create dashboards, alerts, and annotations. Together, they form the de facto standard for cloud-native monitoring and are the backbone of most homelab observability stacks.

Why Use Them for Docker Monitoring?

Container Awareness: cAdvisor exports per-container CPU, memory, network, and filesystem metrics
Service Discovery: Prometheus automatically discovers new containers via Docker labels
Flexible Queries: PromQL allows complex aggregations (e.g., “top 5 containers by memory usage”)
Alerting: Alertmanager routes alerts to Slack, Telegram, PagerDuty, or email
Visual Dashboards: Grafana provides pre-built Docker and Node Exporter dashboards

Why Monitor Your Docker Homelab?

Prevent Resource Exhaustion

A runaway container or memory leak can crash the host. Monitoring reveals trends before they become outages. In a homelab, this means your Plex server stays online during a movie night.

Capacity Planning

Metrics show whether your current hardware is sufficient. If CPU usage is consistently above 80%, it is time to upgrade or consolidate services.

Troubleshooting

When a service slows down, dashboards reveal whether the bottleneck is CPU, disk I/O, or network latency. This replaces guesswork with data.

Deploy:

docker compose up -d

Basic Setup and Configuration

Step 1: Add Prometheus as a Grafana Data Source

Open Grafana at http://your-server:3000
Go to Connections → Data Sources → Add data source
Select Prometheus
URL: http://prometheus:9090
Click Save & Test

Step 2: Import Pre-Built Dashboards

Grafana’s dashboard library has thousands of templates. Recommended dashboards:

Node Exporter Full: ID 1860
Docker and Host Monitoring: ID 179
cAdvisor Exporter: ID 14282

Import via Dashboards → Import → enter the ID.

Step 3: Verify Metrics

In Prometheus (http://your-server:9090), go to Graph and query:

up
node_cpu_seconds_total
container_cpu_usage_seconds_total

You should see time-series data. If up is 0 for a target, check the exporter’s connectivity.

Advanced Features

Recording Rules

Recording rules pre-compute expensive queries. Create /etc/prometheus/rules/rules.yml:

groups:
  - name: docker_rules
    interval: 30s
    rules:
      - record: container:memory_usage_bytes:rate5m
        expr: rate(container_memory_usage_bytes[5m])

Alert Rules

Create /etc/prometheus/rules/alerts.yml:

groups:
  - name: docker_alerts
    rules:
      - alert: HighMemoryUsage
        expr: (container_memory_usage_bytes / container_spec_memory_limit_bytes) > 0.85
        for: 5m
        labels:
          severity: warning
        annotations:
          summary: "Container {{ $labels.name }} high memory usage"
          description: "Memory usage is above 85% for more than 5 minutes."

Grafana Annotations

Annotate dashboards with deployment events. Use the Grafana API or webhooks to mark when a container is updated:

curl -H "Content-Type: application/json" \
  -X POST \
  http://admin:admin@grafana:3000/api/annotations \
  -d '{"dashboardId": 1, "text": "Deployed Nextcloud v28"}'

Integrating with Your Homelab

Reverse Proxy

Expose Grafana via HTTPS:

labels:
  - "traefik.enable=true"
  - "traefik.http.routers.grafana.rule=Host(`grafana.yourdomain.com`)"
  - "traefik.http.routers.grafana.tls.certresolver=letsencrypt"
  - "traefik.http.services.grafana.loadbalancer.server.port=3000"

Loki Integration

Add Grafana Loki as a second data source for log correlation. See our Grafana Loki guide.

Backup

Back up Grafana dashboards and Prometheus data:

# Grafana dashboards
mkdir -p ./grafana-dashboards
curl -s http://admin:admin@localhost:3000/api/search | jq -r '.[].uri' | \
  while read uri; do
    curl -s http://admin:admin@localhost:3000/api/dashboards/$uri > ./grafana-dashboards/$(basename $uri).json
  done

# Prometheus data
sudo tar czf prometheus-backup.tar.gz /var/lib/docker/volumes/monitoring_prometheus_data/_data

Alternatives to Consider

InfluxDB + Telegraf

InfluxDB is a purpose-built time-series database with a SQL-like query language (InfluxQL/Flux). Telegraf is a powerful agent with hundreds of input plugins. This stack is excellent if you prefer SQL-like queries or need to integrate with industrial sensors.

Zabbix

Zabbix is an enterprise monitoring platform with auto-discovery, agent-based monitoring, and native alerting. It is more complex than Prometheus but has a built-in dashboard and no separate Grafana requirement. Good for homelab operators who want an all-in-one solution.

Netdata

Netdata provides real-time, per-second metrics with minimal configuration. It is ideal for quick troubleshooting but has limited long-term storage and query capabilities compared to Prometheus.

Tool	Best For	Query Language	Alerting	Long-Term Storage
Prometheus + Grafana	Cloud-native, Docker	PromQL	Alertmanager	Yes (TSDB)
InfluxDB + Telegraf	SQL-like queries, IoT	InfluxQL/Flux	Native	Yes
Zabbix	Enterprise all-in-one	SQL	Built-in	Yes
Netdata	Real-time troubleshooting	Web UI	Limited	No

Frequently Asked Questions

How much RAM does Prometheus use?

Prometheus memory usage correlates with the number of time-series. A homelab with 1,000 series uses ~500 MB. Limit cardinality by dropping unused labels and reducing scrape frequency.

Can I monitor remote servers?

Yes. Install Node Exporter on each remote server and add it to prometheus.yml:

  - job_name: 'remote-server'
    static_configs:
      - targets: ['192.168.1.20:9100']

How do I update Prometheus?

Update the Docker image and recreate the container. Prometheus data persists in the named volume.

docker pull prom/prometheus:latest
docker compose up -d prometheus

Does Prometheus support push metrics?

Yes, via the Pushgateway. However, pulls are preferred. Use Pushgateway only for batch jobs or ephemeral containers that cannot expose a scrape endpoint.

Conclusion

Summary

Prometheus and Grafana are the gold standard for monitoring Docker-based homelabs. They provide per-container metrics, host health, alerting, and beautiful dashboards — all without cost. With Docker Compose, the entire stack deploys in minutes. With Alertmanager, you are notified before a problem becomes an outage.

Step 3: Import Community Dashboards

Objective

Import battle-tested dashboards for common homelab tools.

Step-by-Step Instructions

In Grafana, click + > Import Dashboard
Enter the dashboard ID and click Load:

Tool	Dashboard ID	Name
Node Exporter	1860	Node Exporter Full
cAdvisor	14282	Docker and System Monitoring
Proxmox	10347	Proxmox via Prometheus
Pi-hole	10176	Pi-hole Exporter
AdGuard Home	14400	AdGuard Home
Unifi	11306	UniFi Poller
pfSense	11694	pfSense Telegraf
Speedtest	13665	Speedtest Tracker

Select your Prometheus data source
Click Import

Step 4: Customize Panels and Variables

Objective

Add template variables so one dashboard serves multiple hosts.

Step-by-Step Instructions

In your dashboard, click Settings > Variables > New Variable
Create a variable named node:
Data source: Prometheus
Query: label_values(node_uname_info, nodename)
Refresh: On Dashboard Load
Multi-value: Yes
Include All option: Yes
Update your queries to use the variable:

# Before
100 - (avg by(instance) (irate(node_cpu_seconds_total{mode="idle"}[5m])) * 100)

# After
100 - (avg by(instance) (irate(node_cpu_seconds_total{mode="idle", nodename=~"$node"}[5m])) * 100)

Now you can select specific hosts or “All” from a dropdown at the top of the dashboard.

Step 5: Set Up Alerts in Grafana

Objective

Create alerting rules directly in Grafana (separate from Alertmanager).

Step-by-Step Instructions

Go to Alerting > Alert Rules > New Alert Rule
Create a rule for disk space:
Query: 100 * (1 - node_filesystem_avail_bytes / node_filesystem_size_bytes) > 90
Evaluation: Every 1m for 5m
Labels: severity=critical
Contact point: Telegram or Slack
Create a rule for high memory:
Query: 100 * (1 - node_memory_MemAvailable_bytes / node_memory_MemTotal_bytes) > 85
Evaluation: Every 1m for 5m
Labels: severity=warning
Test the alert by temporarily lowering the threshold.

Pro Tips

Tip 1: Use Row Panels for Organization

Group related panels into collapsible rows. Common rows for a homelab dashboard: - Overview: CPU, memory, disk, uptime - Network: Traffic, errors, top talkers - Containers: CPU, memory, restart count - Storage: ZFS pool health, disk temperatures, IOPS - Services: Per-service panels (Nextcloud, Plex, Jellyfin)

Tip 2: Add Annotations for Events

Grafana annotations mark events on the timeline. Use the API to add annotations for deployments, reboots, or backups:

curl -X POST http://grafana:3000/api/annotations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "dashboardId": 1,
    "panelId": 1,
    "time": '"$(date +%s)000"',
    "tags": ["deployment", "nextcloud"],
    "text": "Deployed Nextcloud 30.0.1"
  }'

Tip 3: Export and Version Control Your Dashboards

Dashboard JSON should be in Git. Export via Share > Export > Save to file. Commit to a repo and use Grafana provisioning to auto-deploy. This prevents losing work and makes migrations trivial.

Troubleshooting Common Issues

Problem 1: “No Data” in Panels

Check: Ensure Prometheus is scraping the target. Go to Explore in Grafana and run the query manually. If no data, check the target in Prometheus (http://prometheus:9090/targets).

Fix: Common causes: wrong job name, container not on the same Docker network, or firewall blocking port 9100.

Problem 2: Dashboard Variables Not Working

Check: Verify the variable query returns values in Explore.

Fix: If the variable is empty, the label name may be wrong. Use label_values(node_uname_info) to see all available labels.

Problem 3: Slow Dashboard Loading

Check: Complex queries with high cardinality (many unique label combinations) can slow Grafana.

Fix: Add aggregation. Instead of container_cpu_usage_seconds_total, use sum by(name) (container_cpu_usage_seconds_total). Limit time ranges. Use recording rules in Prometheus for expensive queries.

Conclusion

Summary

Grafana is the visualization layer that makes your Prometheus data actionable. A well-built homelab dashboard gives you proactive insight into CPU, memory, disk, network, and container health. Community dashboards provide a fast starting point; custom panels and variables tailor the experience to your infrastructure.

Grafana Loki Logs: The Ultimate Self-Hosted Guide for 2026

2026-06-04T20:35:00+07:00

Reading time: ~14 minutes Audience: Homelab and self-hosting enthusiasts

What Is Grafana Loki?

Overview

Grafana Loki is a horizontally scalable, highly available, multi-tenant log aggregation system inspired by Prometheus. Unlike traditional ELK stacks (Elasticsearch, Logstash, Kibana), Loki indexes only the metadata (labels) of logs and leaves the log content unindexed. This makes it dramatically cheaper to run and easier to operate on homelab hardware. You store logs in object storage or local filesystems, and query them with LogQL, a Prometheus-style query language.

A Brief History

Loki was created by Grafana Labs and first announced in 2018. It was designed to solve the operational complexity and cost of running Elasticsearch at scale. Version 1.0 arrived in 2019. Since then, Loki has gained features like recording rules, alerting, structured metadata, and a native Helm chart. For homelab use, Loki’s “single binary” mode is sufficient — no need for distributed microservices.

Why Use Loki in Your Homelab?

Lower Resource Footprint Than ELK

Elasticsearch requires significant RAM (JVM heap) and CPU for indexing. Loki, in contrast, can run comfortably on a Raspberry Pi 4 or a small VPS. The core Loki container in single-binary mode uses under 200 MB RAM. For a homelab with limited hardware, this is the difference between running a log stack and not running one.

Native Prometheus-Style Labeling

If you already run Prometheus, Loki feels familiar. You label logs with job, instance, container, and custom labels. You query with LogQL, which uses a similar syntax to PromQL. This reduces cognitive load when switching between metrics and logs.

Deep Integration with Grafana

Grafana has a native Loki data source. You can plot log volume over time, jump from a metric alert to the logs of the affected container, and use “derived fields” to link log lines to traces or external systems. This is the same stack used in Grafana Cloud, just self-hosted.

Installation

Prerequisites

Docker and Docker Compose installed
Grafana already running (or deploy it alongside Loki)
At least 1 GB RAM available for the Loki + Promtail stack
A directory for persistent log storage

Method 1: Docker Compose with Local Storage

This is the recommended homelab setup. It runs Loki, Promtail, and Grafana in a single Compose stack.

  filename: /tmp/positions.yaml

clients:
  - url: http://loki:3100/loki/api/v1/push

scrape_configs:

    static_configs:
      - targets:
          - localhost
        labels:
          job: containerlogs
          __path__: /var/lib/docker/containers/*/*.log

          - localhost
        labels:
          job: varlogs
          __path__: /var/log/*.log

Deploy:

docker compose up -d

Method 2: Docker Swarm Service

If you run Docker Swarm, deploy Loki as a global service:

docker service create \
  --name loki \
  --publish 3100:3100 \
  --mount type=bind,source=/var/log,destination=/var/log,readonly \
  --mount type=bind,source=/var/lib/docker/containers,destination=/var/lib/docker/containers,readonly \
  --mount type=bind,source=/path/to/loki-config.yaml,destination=/etc/loki/local-config.yaml,readonly \
  --mode replicated \
  --replicas 1 \
  grafana/loki:latest \
  -config.file=/etc/loki/local-config.yaml

Basic Setup and Configuration

Step 1: Add Loki as a Grafana Data Source

Open Grafana at http://your-server:3000
Go to Connections → Data Sources → Add data source
Select Loki
URL: http://loki:3100 (if in the same network) or http://your-server-ip:3100
Click Save & Test

Step 2: Query Logs with LogQL

LogQL queries have the form:

{label="value"} |= "search string" | json | line_format "{{.field}}"

Examples:

# All container logs
{job="containerlogs"}

# Logs from a specific container
{job="containerlogs"} |= "nginx"

# Parse JSON logs and extract a field
{job="containerlogs"} | json | level="error"

# Logs in the last 5 minutes
{job="containerlogs"} |= "error" [5m]

Step 3: Build a Dashboard

In Grafana, create a dashboard with a Logs panel. Use the query {job="containerlogs"} and set the refresh interval to 5s. You now have a live tail of all Docker containers. Add a Time series panel with rate({job="containerlogs"} |= "error" [1m]) to visualize error frequency.

Advanced Features

Recording Rules and Alerting

Loki supports recording rules and alerting via the Ruler component. In single-binary mode, enable the ruler in loki-config.yaml:

ruler:
  alertmanager_url: http://alertmanager:9093
  ring:
    kvstore:
      store: inmemory
  rule_path: /loki/rules
  storage:
    type: local
    local:
      directory: /loki/rules

Create a rule file /loki/rules/fake/error-rate.yml:

groups:
  - name: container_errors
    interval: 1m
    rules:
      - alert: HighErrorRate
        expr: |
          rate({job="containerlogs"} |= "error" [5m]) > 1
        for: 5m
        labels:
          severity: warning
        annotations:
          summary: "High error rate detected"

Structured Metadata (JSON Logging)

Modern applications emit structured JSON logs. Promtail can parse these automatically with the json stage:

scrape_configs:
  - job_name: app
    static_configs:
      - targets:
          - localhost
        labels:
          job: myapp
          __path__: /var/log/myapp.log
    pipeline_stages:
      - json:
          expressions:
            level: level
            message: message
      - labels:
          level:

This creates a level label in Loki, allowing you to query {job="myapp", level="error"} directly.

Multi-Tenant and Retention

For a shared homelab or family setup, you can enable multi-tenancy by setting auth_enabled: true and passing X-Scope-OrgID headers. In single-tenant mode, control retention with limits_config.retention_period (e.g., 720h for 30 days). Old chunks are automatically deleted.

Integrating with Your Homelab

Docker Driver Plugin

Instead of Promtail, you can send logs directly from Docker to Loki using the loki-docker-driver plugin:

docker plugin install grafana/loki-docker-driver:latest --alias loki --grant-all-permissions

Then add to /etc/docker/daemon.json:

{
  "log-driver": "loki",
  "log-opts": {
    "loki-url": "http://localhost:3100/loki/api/v1/push",
    "loki-batch-size": "400"
  }
}

Restart Docker. All containers now log to Loki automatically.

Alertmanager Integration

Route Loki alerts to Alertmanager, then to PagerDuty, Slack, or a simple webhook. In a homelab, a Slack webhook or Matrix notification is often sufficient.

# alertmanager.yml
route:
  receiver: "slack"
receivers:
  - name: "slack"
    slack_configs:
      - api_url: "https://hooks.slack.com/services/YOUR/WEBHOOK/URL"
        channel: "#homelab-alerts"
        title: "Homelab Alert"
        text: "{{ .CommonAnnotations.summary }}"

Alternatives to Consider

ELK Stack (Elasticsearch, Logstash, Kibana)

The ELK stack is the most mature log platform. It offers full-text search, powerful aggregation, and a massive plugin ecosystem. However, it requires 4+ GB RAM and significant tuning. Use ELK if you need complex full-text search or if you already have Elasticsearch expertise.

Vector

Vector (by Datadog) is a modern log and metrics pipeline. It can replace both Promtail and Logstash. It has a more expressive transform language (VRL) and better performance. If you want a single binary for all telemetry, consider Vector + Loki as sinks.

syslog-ng / rsyslog

For simple, low-volume log aggregation, a traditional syslog daemon forwarding to a central server may be enough. You lose the query power of LogQL but gain simplicity and zero container overhead.

Tool	Best For	Resource Use	Query Power
Loki	Homelab, cloud-native, Docker	Low	Medium (LogQL)
ELK	Enterprise, full-text search	High	Very High
Vector	Modern pipelines, VRL	Medium	High (VRL)
syslog-ng	Simple forwarding, legacy	Very Low	Low

Frequently Asked Questions

How much storage does Loki need?

This depends entirely on log volume. A homelab generating 100 MB/day of logs will use ~3 GB/month. Loki’s filesystem storage with compression is efficient. For longer retention, switch to S3-compatible object storage (MinIO, Wasabi, Hetzner Object Storage).

Can I run Loki without Docker?

Yes. Grafana publishes binary releases for Linux, Windows, and macOS. Download the binary and run ./loki -config.file=loki-config.yaml. However, Docker is strongly recommended for homelab use because it simplifies networking and updates.

How do I forward logs from remote servers?

Install Promtail on each remote server and point it to your central Loki instance. Ensure the Loki port (3100) is accessible over the network or via a VPN tunnel. For untrusted networks, place Loki behind a reverse proxy with TLS or use a WireGuard tunnel.

Does Loki support alerting?

Yes, via the Ruler component. You can define LogQL-based alert rules and send them to any Alertmanager-compatible receiver. For homelab use, alerting on error rates and container crashes is the most common pattern.

Conclusion

Summary

Grafana Loki is the optimal log aggregation solution for homelab environments. It provides Prometheus-style labeling, deep Grafana integration, and a resource footprint that fits on a mini PC or Raspberry Pi. With Promtail, you can ingest Docker container logs, system logs, and application logs from multiple hosts. With LogQL and recording rules, you can query, alert, and visualize your infrastructure’s narrative.

Next Steps

Add the Loki data source to your existing Grafana instance
Configure Promtail to read application logs from specific directories

Reading time: ~15 minutes Audience: Homelabbers building a monitoring stack from scratch

What Is Grafana + Prometheus?

Overview

Grafana + Prometheus is the de facto standard for cloud-native monitoring. Prometheus collects metrics via HTTP scraping. Grafana visualizes them. Together, they provide a complete observability platform for your homelab: server health, container performance, network traffic, and application metrics.

Stack components: - Prometheus: Time-series database and scraper - Grafana: Visualization and alerting UI - Node Exporter: Exposes Linux hardware and OS metrics - cAdvisor: Exposes Docker container metrics - Alertmanager: Routes fired alerts to notifications

Why This Stack in 2026

The Prometheus ecosystem is larger than ever. Every major homelab tool (Proxmox, TrueNAS, Pi-hole, AdGuard Home, Syncthing) has a Prometheus exporter. Grafana’s dashboard library (grafana.com/dashboards) has 10,000+ pre-built dashboards. The stack is mature, well-documented, and completely free.

Reload Prometheus configuration:

curl -X POST http://localhost:9090/-/reload

Check rules in Prometheus UI: Status > Rules

Step 3: Import Dashboards

Objective

Import pre-built dashboards for Node Exporter and cAdvisor.

Step-by-Step Instructions

In Grafana, click + > Import Dashboard
Enter ID 1860 (Node Exporter Full) and click Load
Select the Prometheus data source and click Import
Repeat for ID 14282 (Docker and System Monitoring)

Other useful dashboard IDs:

Dashboard	ID	Description
Node Exporter Full	1860	Comprehensive Linux metrics
Docker and System	14282	Container + host metrics
Proxmox	10347	Proxmox VE metrics via Prometheus
Pi-hole	10176	DNS query statistics
AdGuard Home	14400	AdGuard Home metrics
Speedtest	13665	Internet speed tracking

Step 4: Add Additional Exporters

Objective

Monitor services that do not expose Prometheus metrics natively.

Step-by-Step Instructions

Pi-hole Exporter:

  pihole-exporter:
    image: ekofr/pihole-exporter:latest
    container_name: pihole-exporter
    environment:
      - PIHOLE_HOSTNAME=192.168.1.10
      - PIHOLE_API_TOKEN=***    ports:
      - "9617:9617"
    networks:
      - monitoring

Add to prometheus.yml:

  - job_name: 'pihole'
    static_configs:
      - targets: ['pihole-exporter:9617']

Proxmox VE Exporter:

  proxmox-exporter:
    image: prompve/prometheus-pve-exporter:latest
    container_name: proxmox-exporter
    environment:
      - PVE_USER=root@pam
      - PVE_PASSWORD=***      - PVE_HOST=192.168.1.5
    ports:
      - "9221:9221"
    networks:
      - monitoring

Add to prometheus.yml:

  - job_name: 'proxmox'
    static_configs:
      - targets: ['proxmox-exporter:9221']

Step 5: Secure the Stack

Objective

Expose Grafana and Prometheus securely via reverse proxy.

Step-by-Step Instructions

Add Traefik or Nginx Proxy Manager to the compose file, or use an existing reverse proxy.
Nginx Proxy Manager configuration:
Add proxy host: grafana.yourdomain.com → http://grafana:3000
Add proxy host: prometheus.yourdomain.com → http://prometheus:9090
Request SSL certificates via Let’s Encrypt
Restrict Prometheus access:
Do not expose Prometheus directly to the internet
Use a VPN or internal network for Prometheus access
Grafana can proxy Prometheus queries safely
Enable Grafana HTTPS:

    environment:
      - GF_SERVER_PROTOCOL=https
      - GF_SERVER_CERT_FILE=/etc/grafana/cert.pem
      - GF_SERVER_CERT_KEY=/etc/grafana/key.pem

Pro Tips

Tip 1: Use Recording Rules for Expensive Queries

Queries that aggregate over large time ranges can be slow. Pre-compute them with recording rules:

# prometheus/rules/recordings.yml
groups:
  - name: recordings
    interval: 60s
    rules:
      - record: instance:node_cpu:rate5m
        expr: avg by(instance) (irate(node_cpu_seconds_total{mode!="idle"}[5m]))

Tip 2: Separate Data Retention

Prometheus defaults to 15 days. For long-term storage, use remote_write to VictoriaMetrics or InfluxDB:

# prometheus.yml
remote_write:
  - url: http://victoriametrics:8428/api/v1/write

Tip 3: Backup Your Grafana Dashboards

Dashboards live in the Grafana database. Export them regularly:

# Export all dashboards
curl -s -H "Authorization: Bearer *** http://grafana:3000/api/search | \
  jq -r '.[].uri' | \
  while read uri; do
    curl -s -H "Authorization: Bearer *** "http://grafana:3000/api/dashboards/$uri" > "${uri//\//_}.json"
  done

Troubleshooting Common Issues

Problem 1: Prometheus Targets Show “DOWN”

Check: http://prometheus:9090/targets

Fix: - Ensure the target container is on the monitoring network - Check firewall rules on the host - Verify the scrape URL and port are correct

Problem 2: cAdvisor Shows No Containers

Check: Run docker logs cadvisor

Fix: cAdvisor requires privileged mode and access to /var/lib/docker. On Docker rootless, cAdvisor may not work. Use a non-rootless Docker setup or switch to the Docker daemon metrics endpoint.

Problem 3: Grafana “No Data” for Some Panels

Check: Open the panel in edit mode and run the query in Explore.

Fix: The dashboard may use metric names that differ from your exporter version. Update the query or import a newer dashboard version.

Conclusion

Summary

Grafana + Prometheus is the most powerful, flexible, and well-supported monitoring stack for homelabs. With Node Exporter for hardware metrics, cAdvisor for containers, and community dashboards for every tool, you can build a professional-grade observability platform in under an hour.

Next Steps

Deploy the stack on your Proxmox host or a dedicated monitoring VM
Import the Node Exporter Full and Docker dashboards
Add exporters for your critical services (Pi-hole, Proxmox, TrueNAS)

Home Server Docker Setup: Build a Self-Hosted Container Platform for 2026

2026-06-04T20:35:00+07:00

Reading time: ~16 minutes Audience: Homelab and self-hosting enthusiasts

What Is a Home Server Docker Setup?

Overview

A home server Docker setup is a dedicated machine — typically a mini PC, old desktop, or NAS — running Linux and Docker Engine to host self-hosted applications. Unlike running apps directly on the host OS, Docker containers encapsulate each service with its dependencies, enabling consistent deployment, easy updates, and rapid rollback. This is the dominant architecture in modern homelabs because it is portable, reproducible, and resource-efficient.

Why Docker for a Home Server?

Isolation: A crashing application does not affect the host or other services
Dependency Management: Each container ships with its own libraries and runtime
Reproducibility: A docker-compose.yml file defines the entire stack; deploy it on any machine
Efficiency: Containers share the host kernel, using less RAM and CPU than VMs
Ecosystem: Thousands of pre-built images for homelab apps (Nextcloud, Plex, Pi-hole, etc.)

Prerequisites

Hardware Requirements

Component	Minimum	Recommended	Notes
CPU	2 cores	4+ cores	Intel N100, i3, or Ryzen 3
RAM	4 GB	8–16 GB	More RAM = more containers
Storage	128 GB SSD	1 TB NVMe SSD	Containers are I/O-heavy
Network	1 Gbps	2.5 Gbps	For NAS or media streaming
Power	~15W	35–65W	Mini PCs are ideal

Recommended hardware: Intel N100 mini PC (Beelink U59 Pro, Minisforum UN100), used ThinkCentre M720q, or a refurbished Dell OptiPlex.

sudo ufw default allow outgoing
sudo ufw allow 22/tcp    # SSH
sudo ufw allow 80/tcp    # HTTP
sudo ufw allow 443/tcp   # HTTPS
sudo ufw enable

# Harden SSH
sudo sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin no/' /etc/ssh/sshd_config
sudo sed -i 's/#PasswordAuthentication yes/PasswordAuthentication no/' /etc/ssh/sshd_config
sudo systemctl restart sshd

# Enable automatic updates
sudo apt install -y unattended-upgrades
sudo dpkg-reconfigure -plow unattended-upgrades

# Configure Docker daemon for security
sudo tee /etc/docker/daemon.json <<EOF
{
  "live-restore": true,

  },
  "no-new-privileges": true,
  "userland-proxy": false
}
EOF
sudo systemctl restart docker

Step 5: Deploy Your First Stack

Objective

Deploy a foundational stack: a reverse proxy, a dashboard, and a monitoring agent.

docker-compose.yml

version: "3.8"

services:
  traefik:
    image: traefik:v3.0
    container_name: traefik
    restart: always
    command:
      - "--api.dashboard=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.letsencrypt.acme.tlschallenge=true"
      - "--certificatesresolvers.letsencrypt.acme.email=you@example.com"
      - "--certificatesresolvers.letsencrypt.acme.storage=/letsencrypt/acme.json"
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./letsencrypt:/letsencrypt
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.traefik.rule=Host(`traefik.local`)"
      - "traefik.http.routers.traefik.service=api@internal"

  whoami:
    image: traefik/whoami
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.whoami.rule=Host(`whoami.local`)"

  portainer:
    image: portainer/portainer-ce:latest
    container_name: portainer
    restart: always
    ports:
      - "9000:9000"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - portainer_data:/data
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.portainer.rule=Host(`portainer.local`)"

volumes:
  portainer_data:

Deploy

cd ~/homelab/stacks
docker compose up -d

Pro Tips

Tip 1: Use a Reverse Proxy from Day One

Even for internal services, a reverse proxy (Traefik or Nginx Proxy Manager) provides clean URLs, automatic HTTPS, and centralized access control. Do not expose raw ports.

Tip 2: Version-Control Your Compose Files

cd ~/homelab
 git init
 git add .
 git commit -m "Initial homelab stack"

This creates a recoverable history. If a change breaks a service, git checkout the previous version.

Tip 3: Backup Named Volumes

# Backup all named volumes
docker volume ls -q | while read vol; do
  docker run --rm -v "$vol":/data -v ~/homelab/backups:/backup alpine \
    tar czf "/backup/$vol-$(date +%F).tar.gz" -C /data .
done

Automate with cron.

Tip 4: Monitor Resource Usage

Install ctop for real-time container stats:

sudo docker run --rm -ti \
  --name=ctop \
  --volume /var/run/docker.sock:/var/run/docker.sock:ro \
  quay.io/vektorlab/ctop:latest

Troubleshooting Common Issues

Problem 1: Docker Service Fails to Start

# Check logs
sudo journalctl -u docker.service

# Verify daemon.json syntax
sudo python3 -m json.tool /etc/docker/daemon.json

Problem 2: Container Cannot Reach the Internet

# Check if Docker's iptables rules are present
sudo iptables -L -n -v | grep DOCKER

# Restart Docker to recreate rules
sudo systemctl restart docker

Problem 3: Permission Denied on Volumes

# Check container user ID
docker exec <container> id

# Fix host permissions
sudo chown -R 1000:1000 ~/homelab/stacks/<service>

Conclusion

Summary

A home server running Docker is the most flexible, efficient, and maintainable homelab architecture. With a minimal Linux base, official Docker packages, proper storage, and basic hardening, you can host a dozen services on a $150 mini PC. The key to success is declarative configuration (Compose files), version control, and automated backups.

Homelab Ethernet Cabling: A Complete Guide for Self-Hosters

2026-06-04T20:35:00+07:00

Reading time: ~12 minutes Audience: Homelabbers building or upgrading their physical network

What Is Homelab Ethernet Cabling?

What Exactly Is It?

Ethernet cabling is the physical layer of your homelab network. While Wi-Fi is convenient for phones and laptops, a reliable homelab runs on wired connections: servers, NAS devices, switches, routers, and access points all need Cat5e, Cat6, or Cat6a cables to move data at gigabit speeds and beyond. Good cabling is invisible when it works and a nightmare when it fails.

A Brief History

Category-rated twisted-pair cabling has been the standard for Ethernet since the 1990s: - Cat5 (1995): 100 MHz, up to 100 Mbps. Obsolete. - Cat5e (2001): 100 MHz, up to 1 Gbps. Still viable for most homelabs. - Cat6 (2002): 250 MHz, up to 1 Gbps at 100m, 10 Gbps at 55m. The modern default. - Cat6a (2008): 500 MHz, up to 10 Gbps at 100m. Required for 10GbE over copper. - Cat7/Cat8 (2010/2013): Shielded, 600–2000 MHz, 25–40 Gbps. Overkill for homelabs but future-proof.

Why It Matters Today

In 2026, 2.5 GbE and 10 GbE are mainstream in homelabs. A single 4K Plex stream consumes ~25 Mbps; 10 GbE backups between a NAS and a server can saturate a link. Cheap Cat5e will not reliably carry 10 Gbps. The cabling you install today will outlive the devices you plug into it.

Why Proper Cabling Matters

Benefit 1: Stability Over Wi-Fi

Wi-Fi is shared spectrum. Neighbors, microwaves, baby monitors, and Bluetooth all interfere. A wired Ethernet connection provides deterministic latency, zero jitter, and full duplex bandwidth. For Proxmox clusters, iSCSI storage, and SMB file transfers, Wi-Fi is not an option.

Benefit 2: PoE Power Delivery

Power over Ethernet (PoE) eliminates wall adapters for access points, cameras, and IoT devices. A single Cat6 cable can carry 1 Gbps of data + 15–90 W of power. A centrally located PoE switch (like a TP-Link Omada or Ubiquiti UniFi switch) simplifies cable management and power distribution.

Benefit 3: Future-Proofing

Running a cable is 90% labor. The copper is cheap. Installing Cat6a instead of Cat5e costs ~20% more in materials but adds a 10-year runway for 10 GbE upgrades without rewiring.

Core Principles

Principle 1: Use the Right Category for the Speed

Speed	Cable Required	Max Distance	Typical Use
100 Mbps	Cat5e	100m	Legacy IoT, IP cameras
1 Gbps	Cat5e / Cat6	100m	General homelab, servers
2.5 Gbps	Cat5e (good quality) / Cat6	100m	Modern NAS, mini PCs
5 Gbps	Cat6	100m	High-end workstations
10 Gbps	Cat6a / Cat7	100m	Server interconnects, 10GbE switches
25 Gbps+	Cat8 / fiber	30m	Data center, not homelab

Rule of thumb: For new installations in 2026, use Cat6 for runs under 55m and Cat6a for runs over 55m or where 10 GbE is planned. Cat5e is acceptable for existing runs but do not install new Cat5e.

Principle 2: Terminate Properly

A bad crimp is the #1 cause of “intermittent” network issues. Poor contact between the copper and the RJ45 pin creates resistance, which increases with temperature and vibration.

Tools you need: - Cable tester: A $15 wire mapper or a $60 Klein Tools LAN tester. Test every cable after termination. - Crimp tool: Ratchet-style RJ45 crimpers are ~$20. Pass-through connectors make the job easier for beginners. - Cable stripper: A rotary stripper ($10) prevents nicking the inner conductors. - Punch-down tool: For keystone jacks and patch panels. $15 for a basic impact tool.

Wiring standards: Use T568B for all terminations. It is the dominant standard in North America and most of the world. T568A is electrically identical but less common. Mixing A and B on the same cable creates a crossover cable, which modern Auto-MDIX handles but should be avoided intentionally.

Pin	T568B Color	T568A Color
1	White/Orange	White/Green
2	Orange	Green
3	White/Green	White/Orange
4	Blue	Blue
5	White/Blue	White/Blue
6	Green	Orange
7	White/Brown	White/Brown
8	Brown	Brown

Principle 3: Plan Your Cable Runs

The “home run” model: Every cable runs from a central location (network rack or patch panel) to an endpoint. No daisy-chaining. This gives you maximum flexibility for reconfiguring VLANs and troubleshooting.

Planning checklist: 1. Measure each run with a string, then add 10% for service loops. 2. Avoid running parallel to electrical wiring within 12 inches. If you must cross, do it at 90 degrees. 3. Use J-hooks or cable trays in unfinished spaces. Do not staple cables tight—twisted pair needs some slack to maintain its geometry. 4. Label both ends of every cable. A $10 label maker pays for itself in frustration saved. 5. Leave a 3-foot service loop at each end for re-termination.

Applying This to Your Homelab

Homelab Setup Example: Apartment Lab

Constraints: No permanent modifications, rented space, limited closet.

Solution: Use flat Cat6 cables along baseboards, under doors, and behind furniture. They are ~3mm thick, paintable, and do not require drilling. A 10-pack of 10-foot flat Cat6 cables costs $15. Use command strips to attach them to walls.

Layout: - 1x cable from router to central mini PC (Proxmox host) - 1x cable from router to NAS - 1x cable from router to desk workstation - 1x cable from router to living room TV (for Plex/shield) - 1x cable from PoE switch to ceiling-mounted access point

Homelab Setup Example: Rack Lab

Constraints: Dedicated rack, permanent installation, future 10 GbE.

Solution: Install a 24-port patch panel at the top of the rack. Run Cat6a from the patch panel to wall jacks in adjacent rooms. Use color-coded patch cables (red = management, blue = production, yellow = IoT) in the rack.

Rack cable management: - Horizontal cable managers (1U) keep patch cables orderly. - Velcro straps (not zip ties) allow easy reconfiguration. - 6-inch patch cables for switch-to-patch-panel connections minimize clutter. - A brush panel (1U) at the rear allows cable entry without dust intrusion.

Practical Steps: Making Your First Cable

Measure and cut: Cut cable to length + 2 inches.
Strip: Use the rotary stripper to remove 1.5 inches of jacket. Do not nick the pairs.
Untwist: Untwist the pairs and arrange them in T568B order.
Trim: Align the wires and trim them to 0.5 inches from the jacket.
Insert: Push the wires into the RJ45 connector until you see the copper tips in the clear plastic.
Crimp: Use the ratchet crimper. One firm squeeze until the ratchet releases.
Test: Plug both ends into a cable tester. Verify all 8 pins light up in order.

# On Linux, verify link speed after plugging in
ethtool eth0 | grep -E "Speed|Duplex"
# Expected: Speed: 10000Mb/s, Duplex: Full

Common Mistakes to Avoid

Mistake 1: Mixing Shielded and Unshielded Cable

Shielded (STP/FTP) cable requires shielded connectors, shielded patch panels, and proper grounding. If any component in the chain is unshielded, the shielding is worse than useless—it becomes an antenna. For most homelabs, unshielded (UTP) Cat6 is perfectly adequate. Use shielded only if you have industrial EMI sources (welding equipment, large motors) nearby.

Mistake 2: Bending Radius Violations

Ethernet cable has a minimum bend radius: roughly 4x the cable diameter. For standard Cat6, that is ~1 inch (25mm). A sharp 90-degree bend inside a wall box or rack can damage the internal twisted pairs and degrade performance. Use bend radius control clips or D-rings.

Mistake 3: Using CCA (Copper-Clad Aluminum) Cable

CCA cable is aluminum with a thin copper coating. It is cheaper and lighter but has higher resistance and is brittle. It does not meet ANSI/TIA standards. It will overheat under PoE load and may not certify for gigabit. Always buy pure copper cable (look for “solid bare copper” or “BC” in the spec).

Conclusion

Summary

Ethernet cabling is the foundation of every reliable homelab. In 2026, Cat6 is the safe default for new installations, with Cat6a reserved for 10 GbE runs. Proper termination, testing, and cable management prevent the intermittent failures that ruin weekends. Spend the extra $20 on a cable tester and pure copper cable.

Next Steps

Inventory your existing cables and identify Cat5e runs that need upgrading.
Buy a cable tester, crimp tool, and a box of Cat6 cable.
Draw a floor plan and plan your home runs to a central patch panel.
Label everything. Future-you will thank present-you.

Homelab Rack Setup: A Complete Guide for Building a Server Rack in 2026

2026-06-04T20:35:00+07:00

Reading time: ~16 minutes Audience: Homelab and self-hosting enthusiasts

What Is a Homelab Rack?

Overview

A homelab rack is a standardized frame (typically 19 inches wide) that houses servers, network equipment, storage, and power distribution. Racks are measured in “U” units (1U = 1.75 inches / 44.45 mm). A full-size rack is 42U (~6 feet tall), while compact homelab racks range from 6U to 15U. A rack provides organization, cooling efficiency, and a professional aesthetic that turns a cluttered pile of hardware into a maintainable infrastructure.

Why Build a Rack?

Organization: Everything has a defined place; no more loose machines on a shelf
Cooling: Rack-mounted equipment uses front-to-back airflow; a rack with blanking panels and fans creates a controlled thermal environment
Scalability: Add a new server by sliding it into an empty U space
Noise Management: Rack enclosures with sound-dampening panels reduce the noise escaping into your living space

Prerequisites

Hardware Requirements

Component	Minimum	Recommended	Notes
Rack	6U wall-mount	12U–15U floor-standing	Start small; upgrade later
Power	Basic PDU	Metered PDU with surge protection	Consider a UPS
Cooling	Room AC	Rack-mounted exhaust fans	Hot air must leave the rack
Cabling	Cat5e	Cat6 or Cat6a	10GbE-ready
Shelves	1x shelf for non-rack gear	2x shelves + cable management	Mini PCs, UPS, NAS

Knowledge Prerequisites

Basic woodworking or assembly (for DIY racks)
Electrical safety (PDU loading, UPS sizing)
Networking (patch panels, keystone jacks)

Step 1: Choose the Right Rack

Objective

Select a rack size and type that fits your space, budget, and expansion plans.

Step-by-Step Instructions

Rack Type	Best For	Pros	Cons
Wall-mount (6–12U)	Apartments, small rooms	Saves floor space, cheap	Limited depth, weight capacity
Open frame (12—25U)	Garages, basements	Cheap, excellent airflow	No security, noisy
Enclosed cabinet (12–42U)	Living spaces, offices	Quiet, secure, looks professional	Expensive, heavy, needs ventilation
DIY LackRack (€7 IKEA table)	Extreme budget	Almost free	Not durable, shallow depth

Recommended homelab starter: Startech 12U wall-mount or NavePoint 15U enclosed cabinet. Measure your ceiling height and doorways before ordering. A 42U full rack is ~200 lbs empty and will not fit through standard interior doors.

Step 2: Plan Power and UPS

Objective

Calculate power draw and install a UPS and PDU for clean, protected power.

Step-by-Step Instructions

Measure power draw: Use a Kill-A-Watt meter to measure your current gear
Size the UPS: Aim for 20–30% headroom above your measured load. A 600W load needs a 900W (1500VA) UPS
Install a PDU: Rack-mounted PDUs provide 8–12 outlets in a vertical strip. Get a metered PDU to see real-time load
Connect: Wall → UPS → PDU → Servers

Example UPS sizes:

Load	UPS VA	UPS Watt	Runtime (half load)
300W	600VA	360W	~10 min
600W	1500VA	900W	~15 min
1000W	2200VA	1500W	~20 min

# No CLI commands for hardware setup
# Use a Kill-A-Watt or smart PDU for measurement

Step 3: Install Network Equipment

Objective

Mount the router, switch, and patch panel for a clean network backbone.

Step-by-Step Instructions

Mount the patch panel at the top of the rack (closest to cable entry)
Mount the switch below the patch panel
Mount the router/gateway (e.g., UDM Pro) in a middle U space
Use 6-inch patch cables between the patch panel and switch; 1-foot cables are too long and create clutter

Cable color coding:

Color	Use
Blue	LAN / trusted devices
Red	WAN / internet
Yellow	Management / iDRAC / IPMI
Green	VoIP / phones
White	IoT / guest VLAN

Step 4: Rack the Servers and Storage

Objective

Install servers, NAS, and shelves with proper airflow and weight distribution.

Step-by-Step Instructions

Heaviest gear at the bottom: UPS, NAS, and large servers go low to prevent tipping
Use rail kits: Dell, HP, and Supermicro servers need sliding rail kits. Generic rails exist for odd sizes
Blanking panels: Fill empty U spaces with plastic or metal blanks to maintain front-to-back airflow
Cable arms: Optional; they manage rear cables but can obstruct airflow in shallow racks

For non-rack gear (mini PCs, Raspberry Pi clusters, external drives), use a 1U or 2U shelf.

Step 5: Cable Management and Cooling

Objective

Create a clean, maintainable, and thermally stable environment.

Step-by-Step Instructions

Cable management: - Use velcro straps (not zip ties) for easy changes - Route power cables on one side, network on the other - Use horizontal and vertical cable managers (D-ring, brush-strip) - Label both ends of every cable

Cooling: - Install rack-mounted exhaust fans at the top (hot air rises) - Ensure front-to-back airflow: intake at the front, exhaust at the rear - If the rack is enclosed, add a vented door or active fan panel - Keep ambient room temperature below 25°C (77°F)

Pro Tips

Tip 1: Use a Rack Diagram Tool

Before mounting anything, create a rack diagram in Excel, Visio, or RackTables. Assign U spaces and note power/network requirements. This prevents the “I need one more U space” problem after everything is wired.

Tip 2: Sound Dampening

If the rack is in a living space, line the doors with acoustic foam panels. Place the rack on a vibration-dampening mat. Use Noctua fans or low-RPM fans for DIY cooling. A 1U server is always louder than a 4U tower; choose depth and height over density for noise control.

Tip 3: Document Everything

Create a spreadsheet with: - U position, device name, MAC address, IP address, power draw - PDU port assignments - Switch port assignments - VLAN table

Update it every time you make a change.

Tip 4: Future-Proofing

Leave 20–30% of your rack empty. Run extra network cables to the patch panel (even if unused). Use a switch with 10GbE SFP+ ports even if you only use 1GbE now. The cost difference is small; the upgrade path is huge.

Troubleshooting Common Issues

Problem 1: Rack Tips Forward

Ensure the rack is bolted to the floor or wall
Heavy equipment (UPS, NAS) must be at the bottom
Use a rack with adjustable leveling feet

Problem 2: Overheating

Check blanking panels; empty U spaces create hot air recirculation
Verify server fans are spinning (iDRAC/IPMI)
Add exhaust fans or improve room ventilation
Consider a portable AC unit for summer months

Problem 3: Excessive Noise

Replace 40mm fans with Noctua redux or industrialPPC models
Use a sound-dampened enclosed rack
Relocate the rack to a basement, garage, or closet
Use a long HDMI/USB cable to access machines from a quiet room

Conclusion

Summary

A homelab rack transforms scattered hardware into a professional, maintainable, and scalable infrastructure. By choosing the right rack size, planning power and cooling, and implementing disciplined cable management, you create a foundation that grows with your ambitions. Whether you start with a 6U wall mount or a 42U enclosed cabinet, the principles remain the same: airflow, organization, and documentation.

Next Steps

Create a rack diagram and assign U spaces
Measure total power draw and size a UPS
Order cable management accessories (velcro, D-rings, labels)
Plan your 10GbE upgrade path

Homelab Security Monitoring: A Complete Guide for Self-Hosters

2026-06-04T20:35:00+07:00

Reading time: ~14 minutes Audience: Homelabbers who want to know when they are being attacked

What Is Homelab Security Monitoring?

What Exactly Is It?

Security monitoring is the practice of collecting, analyzing, and alerting on events that indicate unauthorized access, misconfiguration, or malicious activity in your self-hosted infrastructure. Unlike a corporate SOC (Security Operations Center), a homelab security stack is typically a single-person operation: you are the analyst, the responder, and the administrator.

A complete homelab security monitoring stack includes: 1. Log aggregation: Centralizing syslog, audit logs, and application logs 2. Host intrusion detection: File integrity monitoring (FIM), rootkit detection, and anomaly detection 3. Network intrusion detection: Suricata or Zeek for packet analysis 4. Vulnerability detection: Scanning for CVEs in containers and OS packages 5. Alerting: Notifying you via Telegram, Slack, or email when something is wrong

Why It Matters Today

A self-hosted homelab is a public target. Every port forwarded, every exposed service, and every default password is a potential entry point. In 2026, automated scanners (Shodan, Censys, and private botnets) probe every IPv4 address continuously. If you run a public-facing service, you are being scanned right now.

Real threats to homelabs: - Credential stuffing: Attackers use leaked password databases against SSH, Nextcloud, and Jellyfin - Container escape: A vulnerable Docker image can grant host-level access - Cryptojacking: Compromised containers mine cryptocurrency using your electricity - Ransomware: Unpatched services (Confluence, Jenkins, etc.) are encrypted for Bitcoin demands

Why It Matters

Benefit 1: You Cannot Defend What You Cannot See

Without monitoring, a compromise is silent. An attacker can lurk for months, pivot between containers, and exfiltrate data before you notice a performance slowdown. Security monitoring turns the lights on.

Benefit 2: Compliance and Learning

If you are studying for security certifications (CompTIA Security+, CISSP, OSCP), a homelab SIEM is the best hands-on training ground. You can generate attack traffic, analyze logs, and write detection rules in a safe environment.

Benefit 3: Insurance for Your Data

You back up your data. Security monitoring is the “backup” for your infrastructure: it tells you when the restore point is needed.

Core Principles

Principle 1: Defense in Depth

No single tool catches everything. Layer your defenses: - Perimeter: Firewall (pfSense/OPNsense) blocks unwanted traffic - Network: VLANs isolate services by trust level - Host: Fail2Ban or CrowdSec blocks brute-force attempts - Application: Vaultwarden enforces strong passwords; 2FA on every admin panel - Monitoring: Wazuh correlates events across all layers

Principle 2: Log Everything, Alert on What Matters

A SIEM that alerts on every failed SSH login will train you to ignore it. Tune your alerts to high-confidence indicators: - File changes in /etc/, /usr/bin/, and container image layers - New listening ports or running processes - Login attempts from non-standard geolocations (if you have a static IP) - CVEs in running container images

Principle 3: Assume Breach

Design your monitoring as if an attacker is already inside. Monitor east-west traffic between containers, not just north-south traffic from the internet. If your Nextcloud container starts talking to a cryptocurrency mining pool, that is a high-fidelity alert.

Applying This to Your Homelab

Homelab Setup Example: Wazuh-Based SIEM

Architecture: - Wazuh Manager: Central server (4 GB RAM, 2 cores, 50 GB SSD) - Wazuh Indexer: Elasticsearch fork for log storage (8 GB RAM recommended) - Wazuh Dashboard: Kibana fork for visualization - Agents: One per monitored host (VM, LXC, or physical)

What Wazuh monitors out of the box: - File integrity (FIM) on /bin, /sbin, /etc, /var/www - Rootkit detection (YARA rules + rootcheck) - Active response (automatically blocks IP after 5 failed SSH attempts) - Docker/container image scanning (CVE database) - CIS benchmark compliance checks

Docker Compose deployment:

services:
  wazuh.manager:
    image: wazuh/wazuh-manager:4.7.2
    hostname: wazuh.manager
    restart: unless-stopped
    ports:

  wazuh-etc:
  wazuh-logs:
  wazuh-queue:
  wazuh-var:
  wazuh-share:

Agent installation (on a Debian/Ubuntu host):

# Add Wazuh repository
curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | gpg --no-default-keyring --keyring gnupg-ring:/usr/share/keyrings/wazuh.gpg --import && chmod 644 /usr/share/keyrings/wazuh.gpg
echo "deb [signed-by=/usr/share/keyrings/wazuh.gpg] https://packages.wazuh.com/4.x/apt/ stable main" | tee /etc/apt/sources.list.d/wazuh.list

# Install agent
apt-get update && apt-get install -y wazuh-agent

# Register with manager
/var/ossec/bin/agent-auth -m <WAZUH_MANAGER_IP>

# Start agent
systemctl daemon-reload
systemctl enable wazuh-agent
systemctl start wazuh-agent

Practical Steps: CrowdSec as a Lightweight Alternative

If Wazuh is too heavy for your setup, CrowdSec is a modern, community-driven IPS/IDS that is lighter and easier to deploy:

# Install CrowdSec
curl -s https://packagecloud.io/install/repositories/crowdsec/crowdsec/script.deb.sh | sudo bash
apt-get install -y crowdsec

# Install a collection (e.g., nginx logs)
cscli collections install crowdsecurity/nginx

# Install a bouncer (e.g., firewall bouncer)
apt-get install -y crowdsec-firewall-bouncer

# View decisions
watch -n 1 cscli decisions list

CrowdSec shares attack intelligence with a global community. If an IP attacks your server, it is automatically blocked on every other CrowdSec user’s firewall. This is ” crowdsourced defense.”

Common Mistakes to Avoid

Mistake 1: Exposing Your SIEM to the Internet

Wazuh Dashboard, Elasticsearch, and Grafana should never be public-facing. Use a VPN (Tailscale, WireGuard) or a reverse proxy with strong authentication to access them. If you must expose a dashboard, put it behind Cloudflare Access or Authelia.

Mistake 2: Ignoring Container Security

Docker containers are not inherently secure. A 2026 audit of Docker Hub images found that 60% of official images had known CVEs. Run Trivy or Wazuh’s container scanning to audit your images:

# Scan a running container for CVEs
trivy image nextcloud:latest

Mistake 3: Alert Fatigue

A SIEM that sends 50 emails per day is a SIEM that will be ignored. Tune your rules: - Use thresholding: “5 failed SSH logins in 10 minutes” not “1 failed SSH login” - Use suppression: “Alert once per hour per source IP” - Use severity: Reserve email for “Critical” and “High”; send “Low” to a log file

Conclusion

Summary

Security monitoring is not optional for a public-facing homelab. Wazuh provides a complete SIEM experience with FIM, rootkit detection, and vulnerability scanning. CrowdSec offers a lightweight, community-driven alternative. The key principles are defense in depth, tuned alerting, and assuming breach.

Next Steps

Deploy Wazuh or CrowdSec on a dedicated VM or LXC
Install agents on every host that faces the internet
Enable FIM on /etc, /usr/bin, and web root directories
Set up alerting to Telegram or Slack
Run a weekly Trivy scan on your Docker images

Home Server Monitoring Dashboard: Build Your Own Observability Hub

2026-06-04T20:35:00+07:00

Reading time: ~15 minutes Audience: Homelab and self-hosting enthusiasts

What Exactly Is It?

A home server monitoring dashboard is a centralized visualization interface that displays the health, performance, and status of your homelab infrastructure. It aggregates metrics (CPU, memory, disk, network), logs (application and system events), and alerts (threshold breaches) into a single pane of glass. The most common stack is Grafana (visualization) + Prometheus (metrics) + Loki (logs), but alternatives like Zabbix, Netdata, and Uptime Kuma are also popular.

A Brief History

Homelab monitoring evolved from simple htop and df -h commands to full observability platforms. Early tools like Nagios and Cacti gave way to Prometheus (2015) and Grafana (2014), which introduced flexible querying and beautiful dashboards. Today, the “modern observability stack” — Prometheus, Grafana, Loki, and Alertmanager — is the standard for homelab operators who want cloud-native monitoring without cloud costs.

Why It Matters Today

Prevent Downtime

A monitoring dashboard reveals problems before they cause outages. A disk filling up, a container crashing, or a network interface dropping packets are all visible in real-time.

Capacity Planning

Metrics show trends. If your NAS storage grows by 10% per month, you can plan an expansion before it fills. If your CPU is consistently at 90%, you know it is time to upgrade.

Troubleshooting

When a service is slow, dashboards help identify the bottleneck. Is it CPU-bound? I/O-bound? Network-latency? Without data, you are guessing.

Core Components

Metrics with Prometheus

Prometheus scrapes time-series data from exporters. For a homelab, the essential exporters are:

Node Exporter: Host metrics (CPU, memory, disk, network, temperature)
cAdvisor: Container metrics (CPU, memory, I/O per container)
Prometheus itself: Monitoring the monitor

Example scrape configuration:

scrape_configs:
  - job_name: 'node'
    static_configs:
      - targets: ['node-exporter:9100']
  - job_name: 'cadvisor'
    static_configs:
      - targets: ['cadvisor:8080']

Visualization with Grafana

Grafana queries Prometheus and renders dashboards. Key panels for a homelab dashboard:

System overview: CPU, memory, disk usage, uptime
Container grid: Per-container CPU and memory
Network traffic: RX/TX per interface
Storage: Disk usage trends, IOPS
Temperature: CPU and sensor temps (if available)

Import dashboard ID 1860 (Node Exporter Full) for a comprehensive starting point.

Logs with Loki

Loki aggregates logs from all containers and system services. Use LogQL to query:

{job="containerlogs"} |= "error"
{job="varlogs"} | json | level="warn"

Alerting with Alertmanager

Prometheus evaluates rules and sends alerts to Alertmanager, which routes them to Slack, Telegram, or email. Example alert:

- alert: DiskSpaceLow
  expr: (node_filesystem_avail_bytes / node_filesystem_size_bytes) < 0.1
  for: 5m
  labels:
    severity: warning
  annotations:
    summary: "Disk space low on {{ $labels.instance }}"

Advanced Features

Uptime Kuma for Service Monitoring

Uptime Kuma is a lightweight, self-hosted uptime monitor with a beautiful UI. It checks HTTP, TCP, ping, and DNS every minute. It is the perfect complement to Grafana for “is the service up?” monitoring.

services:
  uptime-kuma:
    image: louislam/uptime-kuma:latest
    ports:
      - "3001:3001"
    volumes:
      - uptime-kuma:/app/data

Custom Dashboards for Specific Services

Create per-service dashboards for:

Nextcloud: Active users, file operations, storage
Jellyfin: Active streams, transcode sessions, bandwidth
Pi-hole: Queries blocked, top clients, query types
Traefik: Request rates, response codes, latency

Geolocation and Network Maps

Use the Worldmap plugin or GeoIP data to visualize where your traffic originates. Useful for public-facing services and VPN endpoints.

Integrating with Your Homelab

Reverse Proxy

Expose Grafana via HTTPS with Traefik:

labels:
  - "traefik.enable=true"
  - "traefik.http.routers.grafana.rule=Host(`grafana.yourdomain.com`)"
  - "traefik.http.routers.grafana.tls.certresolver=letsencrypt"

Backup

Back up Grafana dashboards and Prometheus data:

# Export all dashboards
mkdir -p dashboards
for uid in $(curl -s http://admin:admin@localhost:3000/api/search | jq -r '.[].uid'); do
  curl -s http://admin:admin@localhost:3000/api/dashboards/uid/$uid > dashboards/$uid.json
done

# Backup Prometheus data volume
docker run --rm -v prometheus_data:/data -v $(pwd):/backup alpine \
  tar czf /backup/prometheus-backup.tar.gz -C /data .

Alternatives to Consider

Tool	Best For	Complexity	Cost
Grafana + Prometheus	Full observability	Medium	Free
Zabbix	All-in-one monitoring	High	Free
Netdata	Real-time, per-second	Low	Free
Uptime Kuma	Uptime checks	Very Low	Free
Nagios	Legacy enterprise	High	Free

Frequently Asked Questions

How much RAM does a monitoring stack need?

Prometheus + Grafana + Loki use ~1 GB RAM for a small homelab. Scale to 2–4 GB for 10+ hosts or long retention.

Can I monitor Windows machines?

Yes. Use the Windows Exporter for Prometheus. It exposes the same metrics as Node Exporter for Windows hosts.

Do I need a dedicated monitoring server?

No. Run the stack on your primary homelab server. If that server fails, you lose monitoring but not the services themselves. For critical infrastructure, run a lightweight monitoring node on a Raspberry Pi.

Conclusion

Summary

A home server monitoring dashboard is essential for any serious homelab. It transforms invisible infrastructure into visible, actionable data. With Prometheus, Grafana, and Loki, you gain the same observability used by cloud providers — on your own hardware, for free.

Configure network:
Hostname: pve.local or pve.mydomain.com
IP address: Static recommended (e.g., 192.168.1.10)
Gateway: Your router IP (e.g., 192.168.1.1)
DNS: 1.1.1.1 or 192.168.1.1
Review summary and confirm installation
Wait 5–10 minutes for installation to complete
Reboot and remove USB

Post-Install First Boot

After reboot, you’ll see the Proxmox VE console:

Welcome to the Proxmox Virtual Environment.

https://192.168.1.10:8006

Step 5: Initial Web UI Configuration

Access Web UI

On another computer, open browser: https://192.168.1.10:8006
Accept self-signed certificate warning
Login with root and your install password
Realm: Linux standard PAM

First Tasks in Web UI

Remove subscription warning (free use is fully allowed) bash # SSH into Proxmox host ssh root@192.168.1.10 sed -i 's/NotSubscribed/Active/g' /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js systemctl restart pveproxy
Update system: bash apt update && apt dist-upgrade -y
Configure storage:
Datacenter → Storage → Add → Directory or ZFS
Upload ISO templates:
Local → ISO Images → Upload
Download Ubuntu, Debian, Windows Server ISOs

Step 6: Create Your First VM

Create a Linux VM

Click “Create VM” (top right)
General: Name ubuntu-test, VM ID 100
OS: Select Ubuntu ISO from dropdown
System: Defaults (QEMU agent: checked)
Disks: 32GB, SCSI, VirtIO SCSI
CPU: 2 cores, host type
Memory: 2048 MB
Network: VirtIO, bridged to vmbr0
Confirm and start VM

Install Ubuntu in VM

Click Console tab
Complete Ubuntu installation normally
After reboot, install QEMU Guest Agent: bash sudo apt install qemu-guest-agent sudo systemctl enable qemu-guest-agent

Step 7: Create Your First LXC Container

Containers are lighter than VMs:

Click “Create CT” (top right)
General: Name nginx-test, CT ID 200
Template: Select ubuntu-22.04-standard (download first if needed)
Disks: 8GB
CPU: 1 core
Memory: 512 MB
Network: DHCP or static IP
Confirm and start container

Install Nginx in Container

# From Proxmox console or SSH into CT
apt update && apt install nginx -y
curl http://localhost
# Should show Nginx welcome page

Performance Tips for Old Hardware

Tip	Why It Helps
Use SSD	10x faster boot than HDD
Enable ZFS compression	Saves space on small SSDs
Use LXC over VMs	10x less RAM per container
Disable GUI on host	Proxmox is headless; save RAM
Enable CPU power saving	`cpufreq-set -g ondemand`
Add RAM	Best upgrade: 16GB enables 5–10 VMs
Use virtio drivers	Best disk/network performance in VMs

Common Installation Issues

Issue 1: “No Network Interface Found”

Cause: Missing NIC driver
Fix: Check if NIC is supported. Realtek NICs may need r8168-dkms package.

apt update
apt install r8168-dkms -y
reboot

Issue 2: “Secure Boot Violation”

Cause: Secure Boot enabled
Fix: Disable Secure Boot in BIOS.

Issue 3: Installation Freezes

Cause: Old USB 2.0 port or bad USB drive
Fix: Use USB 3.0 port, reflash USB, or try Ventoy.

Issue 4: Low Disk Space Warning

Cause: Proxmox needs 32GB+ for root
Fix: Use a larger disk or add external storage via NFS/iSCSI.

Conclusion

Summary

Any old PC with a 64-bit CPU, 4GB+ RAM, and an SSD can run Proxmox VE. Installation takes 15 minutes, and you’ll have a full virtualization platform capable of running VMs, containers, and a complete homelab stack.

Immich Photo Server: The Ultimate Self-Hosted Guide for 2026

2026-06-04T20:35:00+07:00

Reading time: ~15 minutes Audience: Homelab and self-hosting enthusiasts

What Is Immich?

Overview

Immich is a high-performance, self-hosted photo and video management platform designed as a replacement for Google Photos, iCloud, and Amazon Photos. It offers automatic mobile backup, facial recognition, duplicate detection, and a modern web interface. Unlike Nextcloud’s Photos app, Immich is purpose-built for media with a focus on speed, organization, and AI-powered features. It is open-source (MIT license) and actively developed with a large community.

A Brief History

Immich was created by Alex Tran in 2022 out of frustration with Big Tech photo services. The project quickly gained traction on GitHub and Hacker News due to its polished UI and aggressive feature roadmap. By 2024, Immich supported machine learning (CLIP-based search, facial recognition), hardware-accelerated transcoding, and OAuth login. It has become the default recommendation in the self-hosted community for photo management.

Why Use Immich in Your Homelab?

Privacy-First Photo Storage

Your photos are stored on your own hardware. There is no AI training on your data, no facial recognition by third parties, and no risk of account termination causing data loss. For parents, photographers, and privacy advocates, this is non-negotiable.

AI-Powered Search and Organization

Immich uses machine learning models to:

Recognize faces and group photos by person
Classify objects and scenes (beach, dog, sunset)
Generate natural language search (“photos of my dog at the beach”)
Detect duplicates across your library

These models run locally on your server. No data is sent to external APIs.

Automatic Mobile Backup

The Immich mobile app (iOS/Android) supports background upload, RAW file support, and burst photo handling. It can upload over Wi-Fi or cellular, with configurable quality settings (original or compressed). The app is native, fast, and supports offline viewing of recently accessed albums.

Installation

Prerequisites

A Linux server with 2+ vCPUs, 4 GB RAM (8 GB+ recommended for ML)
Docker and Docker Compose
An NVIDIA GPU (optional but strongly recommended for ML tasks)
At least 100 GB storage for photos and ML models

Method 1: Docker Compose (Recommended)

Immich is a multi-service application. The official Compose template includes the server, machine learning service, PostgreSQL, and Redis.

version: "3.8"

services:
  immich-server:
    container_name: immich_server
    image: ghcr.io/immich-app/immich-server:release
    command: ["start.sh", "immich"]
    volumes:
      - ${UPLOAD_LOCATION}:/usr/src/app/upload
    env_file:
      - .env
    ports:
      - 2283:3001
    depends_on:
      - redis

    container_name: immich_redis
    image: redis:7-alpine
    restart: always

  database:
    container_name: immich_postgres
    image: tensorchord/pgvecto-rs:pg14-v0.2.0
    env_file:
      - .env
    environment:
      POSTGRES_PASSWORD: ${DB_PASSWORD}
      POSTGRES_USER: ${DB_USERNAME}
      POSTGRES_DB: ${DB_DATABASE_NAME}
    volumes:
      - pgdata:/var/lib/postgresql/data
    restart: always

volumes:
  pgdata:
  model-cache:

Create .env:

UPLOAD_LOCATION=./library
IMMICH_VERSION=release
DB_PASSWORD=***
DB_USERNAME=postgres
DB_DATABASE_NAME=immich

Deploy:

docker compose up -d

Access the web UI at http://your-server:2283. Create the first admin user.

Method 2: GPU-Accelerated Machine Learning

If you have an NVIDIA GPU, enable CUDA for faster face recognition and object classification:

  immich-machine-learning:
    container_name: immich_machine_learning
    image: ghcr.io/immich-app/immich-machine-learning:release-cuda
    volumes:
      - model-cache:/cache
    env_file:
      - .env
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]
    restart: always

Ensure the NVIDIA Container Toolkit is installed on the host.

Basic Setup and Configuration

Step 1: Configure the Mobile App

Download the Immich app from the App Store or Google Play
Enter your server URL: http://your-server:2283 (or https:// behind a reverse proxy)
Log in with your credentials
Enable Background Upload in settings
Set upload quality to Original (or Compressed to save space)

Step 2: Organize with Albums and Tags

The web UI supports albums, tags, and favorites. Create albums for events (“Vacation 2025”, “Baby’s First Year”). The AI will auto-suggest tags based on content. You can also manually tag photos for precise organization.

Step 3: Run the Machine Learning Pipeline

After uploading photos, the machine learning service processes them in the background. For a large library, this can take hours. Monitor progress in Administration → Jobs. You can manually trigger or pause jobs.

Advanced Features

External Libraries

Immich can ingest photos from existing directories without duplicating them. This is useful if you already have a NAS or a well-organized file structure.

In Administration → External Libraries, add a path
Set the scan schedule (e.g., daily at 2 AM)
Immich will read the files in-place and generate thumbnails

Storage Template

Immich stores files in a flat directory by default. You can configure a storage template to organize files by date:

{{y}}/{{y}}-{{M}}-{{d}}/{{filename}}

This makes it easier to browse the library directly on the filesystem.

Duplicate Detection

Immich runs a duplicate detection job that compares file hashes and perceptual hashes. You can review duplicates in the web UI and choose which to keep. This is invaluable when importing libraries from multiple sources.

OAuth and SSO

Immich supports OpenID Connect (OIDC) for single sign-on. Configure it with Authentik, Keycloak, or Authelia:

OAUTH_ENABLED=true
OAUTH_ISSUER_URL=https://authentik.example.com/application/o/immich/
OAUTH_CLIENT_ID=your-client-id
OAUTH_CLIENT_SECRET=your-client-secret
OAUTH_BUTTON_TEXT=Login with Authentik

Integrating with Your Homelab

Reverse Proxy and HTTPS

Expose Immich via a reverse proxy with valid HTTPS. The mobile app requires HTTPS for background upload on iOS.

labels:
  - "traefik.enable=true"
  - "traefik.http.routers.immich.rule=Host(`photos.yourdomain.com`)"
  - "traefik.http.routers.immich.tls.certresolver=letsencrypt"
  - "traefik.http.services.immich.loadbalancer.server.port=3001"

Backup Strategy

Back up both the PostgreSQL database and the upload directory:

# Backup database
docker exec immich_postgres pg_dump -U postgres immich > immich-backup.sql

# Backup library
tar czf immich-library-backup.tar.gz ./library

# Or use a backup container
docker run --rm \
  -v immich_postgres:/db:ro \
  -v ./library:/library:ro \
  -v /backup:/backup \
  offen/docker-volume-backup

Sync with rclone

For a 3-2-1 backup strategy, sync the library to cloud storage (S3, B2, Google Drive) with rclone:

rclone sync ./library remote:immich-backup --checksum --verbose

Alternatives to Consider

Nextcloud Photos

Nextcloud has a Photos app and a Memories app (a more advanced fork). Nextcloud is better if you want a unified platform (files, documents, photos). Immich is better if you want a dedicated, AI-powered photo experience. See our Nextcloud vs Immich comparison.

PhotoPrism

PhotoPrism is another AI-powered photo manager with a focus on privacy and archiving. It has a stronger emphasis on geo-tagging and map-based browsing. The UI is more “gallery-like” than Immich’s social feed style. PhotoPrism requires a commercial license for some features (high-resolution viewers, advanced AI).

LibrePhotos

LibrePhotos is an open-source photo manager with face recognition and auto-tagging. It is less polished than Immich but has a strong community. Good if you want a fully free alternative without the “release model” complexity.

Tool	Best For	AI	Mobile App	Cost
Immich	Modern replacement for Google Photos	Yes	Yes	Free
Nextcloud Photos	Unified file+photo platform	Limited	Yes	Free
PhotoPrism	Archival, geo-browsing	Yes	Web app	Free / Pro
LibrePhotos	Fully open, community-driven	Yes	No	Free

Frequently Asked Questions

How much storage does Immich need?

Immich stores originals and generates thumbnails, encoded videos, and ML embeddings. Budget 2–3x the size of your raw library. A 100 GB photo library will consume 200–300 GB on Immich.

Can I run Immich without a GPU?

Yes. The machine learning service falls back to CPU. Face recognition and object detection will be slower but functional. A modern CPU with AVX instructions is sufficient.

Is Immich stable for long-term use?

Immich is rapidly evolving. The core storage and API are stable, but the project occasionally introduces breaking changes. Always read the release notes before updating. Back up the database before major version bumps.

How does Immich handle RAW files?

Immich supports RAW formats (CR2, NEF, ARW, DNG). It generates JPEG thumbnails for web viewing and keeps the RAW for download. The mobile app can upload RAW files directly.

Conclusion

Summary

Immich is the best self-hosted photo management solution available today. It combines the convenience of Google Photos — automatic backup, AI search, and a polished mobile app — with the privacy and control of self-hosting. With Docker, it deploys in minutes. With GPU acceleration, the AI features are fast and responsive. For anyone with a growing photo library, Immich is the logical next step.

Next Steps

Why Immich Needs a Reverse Proxy

Immich runs on port 2283 by default. A reverse proxy provides:

SSL termination (HTTPS)
Domain-based routing (photos.mydomain.com)
Rate limiting (protect uploads)
Security headers (HSTS, CSP, X-Frame-Options)
Load balancing (if running multiple instances)

Feature	Without Proxy	With Proxy
HTTPS	Manual cert management	Automatic (Let’s Encrypt)
Domain	IP:2283	photos.mydomain.com
Rate limiting	None	Configurable
Security headers	None	Full HSTS/CSP
Path-based routing	N/A	/api, /share, etc.

Performance Tuning

Nginx Buffer Sizes

Immich .env for Large Libraries

# .env
UPLOAD_LOCATION=/mnt/photos
DB_HOSTNAME=immich_postgres
DB_USERNAME=immich

DB_DATABASE_NAME=immich

Common Mistakes

Mistake 1: Missing WebSocket Support

Immich uses WebSockets for live updates. Ensure your proxy passes Upgrade and Connection headers.

Mistake 2: Too Small `client_max_body_size`

Default Nginx limit is 1MB. Immich uploads need 50GB+ for video. Set:

client_max_body_size 50000M;

Mistake 3: Forgetting `X-Forwarded-Proto`

Immich needs this header to generate correct URLs. All configs above include it.

Conclusion

Summary

Any reverse proxy works with Immich. Caddy is simplest for beginners, Traefik is best for Docker-native stacks, and Nginx offers maximum control for advanced users.
