Kubernetes Operations Lab

A reproducible local-cluster learning lab for readiness, pod replacement, scaling, rolling updates, and rollback exercises.

The source and runbooks live on GitHub. Cluster exercises require a separate authorized Docker/kind environment; this OSU site does not run a Kubernetes cluster.

Problem, implementation and evidence

A running pod can still be unable to serve traffic.

Separate startup, readiness, liveness, endpoint membership and service response when investigating a failure.

What the evidence establishes

Source/manifest evidence and an executed probe-decision fixture; no live cluster rollout was performed in this release.

Reproduce or extend

Run a controlled dependency outage in a disposable cluster and preserve pod events, endpoints, restarts and application responses.
