Troubleshooting Kubernetes refers to the systematic process of identifying, diagnosing, and resolving issues within a Kubernetes cluster. It involves analyzing logs, metrics, and events to pinpoint the root cause of problems affecting containerized applications and the cluster infrastructure itself. This practice is crucial for maintaining the stability, performance, and availability of cloud native applications, ensuring business continuity. For instance, a common scenario involves investigating why a pod is stuck in a 'CrashLoopBackOff' state by examining its container logs for application errors. Unlike general system troubleshooting, Kubernetes troubleshooting requires understanding its distributed architecture, including pods, services, and deployments. This concept is frequently tested on cloud security certifications like CCSP and AWS specialty exams.
