Most of what's here is me documenting the work I do on my homelab — Kubernetes, observability, and whatever else I'm building.

Automating OS updates and kernel reboots across a homelab Kubernetes cluster, and muting the alerts so routine overnight reboots don't wake me up.
Adopting an existing Helm release under ArgoCD on a live Kubernetes cluster, plus the Hubble TLS drift problem that surfaces along the way.
