عرض عملي: Pod يتعطل ويعيد التشغيل باستمرار وتشخيص سببه

خطوة بخطوة

1. kubectl get pods shows orders in CrashLoopBackOff.
2. kubectl describe pod shows restarts and the last state; events show no image problem.
3. kubectl logs --previous reveals a missing configuration value (database URL).
4. Planned mistake: raise memory limits as a guess because the pod "keeps dying". Fix: read the exit reason first; the exit code and logs point to configuration, not memory.
5. Correct the ConfigMap, roll the Deployment, confirm readiness, and write one line for the runbook.
