Kubernetes Troubleshooting Questions

Covers diagnosing and resolving failures in container orchestration with an emphasis on Kubernetes pod and deployment issues. Topics include Kubernetes architecture and components, pod lifecycle and states, common failure modes such as CrashLoopBackOff, ImagePullBackOff, out of memory conditions, resource limit and quota problems, and node or scheduling issues. Practical debugging skills include using command line inspection and control tools, reading and correlating logs and events, using exec into containers, describing resources, checking node and cluster health, and interpreting health checks, liveness and readiness probes. Also includes distinguishing platform or cluster issues from application level faults, analyzing networking and service discovery problems, using monitoring and observability data, understanding rolling updates and deployment strategies, and applying remediation and rollback techniques for reliable recovery.
