Init Containers

Your pod is stuck at Init:0/2. The main container has no logs because it never started. kubectl logs returns an error asking you to pick a container, but the one you need has already exited.

Init containers are the gatekeepers of pod startup. They run sequential setup logic that must complete before your application containers launch. The CKAD curriculum lists them explicitly under "multi-container Pod design patterns," and they show up in production everywhere: Istio configuring iptables, Vault pre-populating secrets, ArgoCD distributing binaries across containers.
