For a container that fails to respond to health checks, what does Kubernetes do?

• A. Automatic restart
• B. Ignore and keep running
• C. Migrate to another node
• D. Kubernetes kills the container

Answer: (D)

When a container stops responding to health checks, Kubernetes treats it as unhealthy and terminates it. The kubelet sends a termination signal to the container, allowing it to shut down gracefully (within the configured termination grace period). If the pod is configured to restart, Kubernetes will then start a new instance of the container according to the restart policy (which is typically Always for deployments). In essence, the failing container is killed so it can be recreated and brought back to a healthy state.
