Troubleshooting Pods and Workloads

Your Pod shows CrashLoopBackOff. But CrashLoopBackOff isn't the error. It's the kubelet telling you it's given up trying for the moment. The actual error is somewhere else: in the Pod's phase, the container's state reason, or the Events section of kubectl describe pod. Knowing where to look is the entire skill.

Troubleshooting falls under the KCNA Container Orchestration domain (22% of the exam). Understanding how Kubernetes reports Pod failures, what each status means, and which tools reveal the root cause is foundational to every certification that follows.
