Container Lifecycle — Certified Kubernetes App Developer (CKAD) Practice Questions
Container lifecycle in Kubernetes covers the sequence of states a container moves through (Waiting, Running, Terminated) as well as the postStart and preStop lifecycle hooks that let developers run commands at specific points during startup and shutdown. The CKAD exam expects candidates to configure lifecycle hooks and understand how init containers separate initialization logic from the main application container. Proper lifecycle management ensures graceful startup and shutdown behavior, which is especially important for applications that need to register with a service or flush state before terminating.
