Interview Questions & Model STAR Responses
Sample STAR Answer:
`CrashLoopBackOff` indicates that Kubernetes started the pod container, but the process repeatedly crashed or exited with a non-zero code. To debug, I follow a systematic triage: 1) Run `kubectl describe pod <name>` to inspect Events (OOMKilled, failed readiness/liveness probes, volume mount errors); 2) Check application logs via `kubectl logs <name> --previous` to see why the crash occurred; 3) Verify environment variables, secrets, and database connectivity.
Key Points to Cover
- Difference between kubectl describe (events/infra) and kubectl logs (app error)
- Common causes: OOM (Out Of Memory), missing ConfigMap/Secrets, failing probes
- Using ephemeral debug containers or interactive sh if pod fails at startup
Common Pitfalls
- Only checking logs without checking describe events or previous crashed container logs
