A self-tuning homelab

Every so often, a pull request like this shows up.

The PR changes a handful of Kubernetes resource requests and limits in the HelmRelease manifests. The description spells out why each change got picked. It shows which containers look underfed, which ones sit on capacity they never touch, and whether the new state still fits on the nodes I actually have. None of that is me. I review it, merge it, and Flux rolls it out.

I have self-hosted things before, but none of it really stuck. A Raspberry Pi 4 ran Pi-hole for a while. Then an old laptop ran Plex for a while after that. Both were useful in the loose way side projects are useful. Something would break, I’d shrug, it would fizzle out, and I’d move on.

This time I wanted something more serious. Small, but with room to grow in whatever direction I felt like, a testing ground for whatever I wanted to learn. I’d GitOps it too. If I added a service, changed storage, or touched DNS, that change should live somewhere more durable than a vague memory of what I typed into a terminal. Nothing fancy. No rack, no enterprise gear. Just a small cluster for the services I actually use, with enough Kubernetes underneath to learn something while running it.
