[bug\_fix] CrashLoopBackOff

Run kubectl describe pod to inspect events and kubectl logs --previous to see the crash output. Fix the underlying cause: repair the application bug, correct command/args, mount the missing ConfigMap/Secret, raise the memory limit if the container is OOMKilled, or increase liveness/startup probe delays. Once the container stays running for about 10 minutes the kubelet resets the exponential backoff.

Journey Context:
A Deployment rollout finishes but the pod shows CrashLoopBackOff and the RESTARTS counter keeps climbing. The events show Back-off restarting failed container. The previous container logs reveal a panic caused by a missing DATABASE\_URL environment variable. After injecting the variable from an existing Secret, the next restart succeeds and the pod stays Running; the backoff delay resets because the kubelet only keeps the backoff while the container keeps failing.
