Cluster Administration

A homelab becomes a platform when it has repeatable operations, not when it has more dashboards.

Topics

  • Cluster Planning - Cluster planning is deciding what failures you are willing to absorb and what complexity you are willing to operate.
  • Cluster Lifecycle - Cluster lifecycle is the repeatable path to install, upgrade, repair, and replace the platform.
  • Addons As Platform Dependencies - Addons are not optional once workloads depend on them. They become part of the platform SLO.
  • Logging - Logs are distributed evidence. Kubernetes gives you streams; you decide retention, routing, and search.
  • Metrics And Health - Metrics turn cluster behavior into signals that humans and controllers can act on.

Editorial Notes

  • Keep the official docs as the citation layer.
  • Keep this lab opinionated around homelab operations: verification, failure modes, and practical boundaries.
  • Avoid copying upstream prose; cite it, then explain the operating model in our own language.
