Example Documentation: Ephemeral Debug Container

Goal

Inspect a faulty Pod with kubectl debug.

What Is Done

The lab creates an NGINX Pod with a broken readiness probe. An ephemeral container can then be injected into the Pod.

Typical Commands

kubectl apply -f manifests/
kubectl describe pod broken-web -n debug-lab
kubectl debug -n debug-lab -it broken-web --image=busybox:1.36.1 --target=web

Validate Success

The Pod runs but does not become ready.
describe shows failed readiness probes.
kubectl debug starts a temporary debug container.

Common Mistakes

RBAC does not allow pods/ephemeralcontainers.
Debug containers are confused with normal sidecars.
Not every runtime or cluster setup allows the same debug features.
