Self-hosting as a catalogue, not a pile

homelab

The second version of my homelab: a K3s cluster with a declarative service catalogue, TLS from cert-manager, secrets encrypted in git, and a Prometheus stack watching all of it. It replaced a Raspberry Pi running Docker Compose.

Tools · Open Source

Highlights
  • A 65-entry service catalogue: 18 installed by default, the rest opt-in
  • 58 of 64 manifests applied cleanly to a real API server, not just linted
  • 31 of 31 Prometheus targets up on the first real deploy
