kubectl for Pods

Apply a manifest

Deploy a Pod:

• kubectl apply -f pod.yml

Check Pods:

• kubectl get pods
• watch continuously:
  • kubectl get pods --watch

Inspect pods with kubectl get

Useful output formats:

• -o wide (more columns)
• -o yaml (full YAML output)

Tip:

• compare desired state (spec) vs observed state (status).

kubectl describe

• kubectl describe pods <pod-name> Useful for events and deep status information.

kubectl logs

• kubectl logs <pod-name>
• for a specific container:
  • kubectl logs <pod-name> --container <container-name>

kubectl exec

Run a command in a running Pod:

• kubectl exec <pod-name> -- <cmd>

Get a tty:

• kubectl exec -it <pod-name> -- sh

For multi-container pods, add --container <container-name> as needed.
