Band: Beginner
Setup: kind cluster learn from first success. Work from 04-kubernetes/ so examples/ paths resolve.
Task: Apply examples/nginx-deployment.yaml and examples/nginx-service.yaml. Scale to 5 replicas, wait until 5 are Ready, scale back to 3.
Hint: kubectl scale deploy/nginx --replicas=5 then kubectl get pods -w.
Success: kubectl get deploy nginx shows 3/3 READY after you scale back.

kubectl apply -f examples/nginx-deployment.yaml -f examples/nginx-service.yaml then the two kubectl scale commands from beginner.md.
