Topic 1: Volumes

Official baseline: (The Kubernetes Authors, 2026). My working version: A Volume is storage mounted into a Pod. Its lifetime and backend depend on the volume type.

Mental Model

A Volume is storage mounted into a Pod. Its lifetime and backend depend on the volume type.

Notes

  • Some volumes die with the Pod; others point to persistent systems.
  • Mount paths are part of application design.
  • Volume choice affects security, portability, and backup.

Homelab Angle

Use temporary volumes for scratch work and make persistence explicit in code review.

Verify It

  • Read the object status before changing the manifest.
  • Check events for the controller or node that is actually complaining.
  • Confirm the official source linked below still matches the cluster version you run.

Common Failure Modes

  • Treating the YAML object as the system, instead of one input to a reconciliation loop.
  • Debugging from outside the cluster when the failure only exists inside cluster networking or node state.
  • Forgetting that Kubernetes version, addon version, and runtime behavior are linked.
