Start Here — Build a Homelab Step by Step

Phase 1

Understand what you're building

Brand new? Start here — what a homelab actually is, and why it's worth building.

Phase 2

Plan & prep

Pick the right hardware, choose a switch, and make a bootable USB — before you touch a keyboard.

Phase 3

Install the base

Install Proxmox, lock it down, understand your storage options — and learn the storage failures to design against from day one.

Phase 4

Create your first workloads

Learn the difference between a container and a VM, then build one of each.

Phase 5

Set up networking

Configure container networking, set up network-wide DNS with Pi-hole, add a firewall, and wall off your IoT gadgets with VLANs.

Phase 6

Reach it from anywhere

Install Tailscale so you can manage the whole lab securely from any device, anywhere — then learn to debug the four ways homelab networks quietly break.

Phase 7

Protect it

Set up automated backups, measure how fast they actually restore, quiet the every-backup emails without losing failure alerts, add a UPS-triggered safe shutdown, and make sure backups reach offsite before you run services you care about.

Phase 8

Serve apps the right way

Run Docker, learn Compose once, keep your stacks updated and backed up, then put every service behind clean HTTPS URLs with a reverse proxy.

Phase 9

See what it is doing · I

Start with dead-simple up/down alerts, then add deep metrics and dashboards for the whole cluster — use that history to answer what happens when a node dies, fold every alert into one daily email you'll actually read, and keep the rescue runbook for the day a service does.

Phase 10

Set up shared storage

Give every service one central place to read and write files — the backbone your photos and media server depend on.

Phase 11

Run real services · I

The payoff — a smart-home hub, private photo backup, a knowledge base, password manager, local AI, and an autonomous agent. Then put it all on one dashboard.

Phase 12

Build a media server

Pick Plex or Jellyfin, install it, keep playback smooth on modest hardware, keep the library tidy, and reach it from anywhere.

Phase 13

Automate your media

The *arr stack, then a request page for the whole house: someone taps Request and it downloads, files itself, and appears in your library — and keeps healing itself when it breaks.

Phase 14

Remember what you built · I

Document your homelab in a Git-backed knowledge base so you never solve the same problem twice — and so your AI tools can read it too.
