Logs and Exec

Fetch logs

Applications should log to stdout/stderr so kubectl can stream them.

kubectl logs deploy/web
kubectl logs deploy/web --tail=100 -f

Pick a pod by name

When multiple replicas exist, target one pod explicitly.

kubectl get pods
kubectl logs web-7d9f8c-abc12

Exec into a container

Interactive debugging shell (image must include a shell).

kubectl exec -it deploy/web -- sh

Prefer durable fixes

Exec is temporary. Fix images, probes, config, or resource requests so the next pod starts healthy without manual steps.
