Pod Lifecycle — Certified Kubernetes App Developer (CKAD) Practice Questions
Pod lifecycle in Kubernetes describes the sequence of phases a pod passes through, from Pending and Running to Succeeded, Failed, or Unknown, along with the conditions and container states within each phase. The CKAD exam tests understanding of init containers, which run to completion before app containers start, and lifecycle hooks such as postStart and preStop that execute at container startup and shutdown. Candidates must also know how liveness, readiness, and startup probes influence whether a pod is considered healthy and whether it receives traffic. Correctly managing the pod lifecycle is essential for building reliable applications that start cleanly, handle graceful shutdown, and recover automatically from failures.
