Learn kubectl rollout & scale
kubectl Commands
Operate a deployment: rollout status to watch, restart to cycle pods, undo to roll back, and scale --replicas to resize.
A Deployment manages rollouts through ReplicaSet revisions, and kubectl rollout drives them.
status blocks until the update completes; restart cycles pods to pick up new config or images; undo reverts to the last revision.
scale --replicas adjusts the running pod count without editing the manifest.
01
rollout status waits for completion.
02
rollout restart cycles all pods.
03
rollout undo reverts a revision.

Connect each part of the code to the concept before you type.
2. Restart pods
restart triggers a rolling replacement of all pods, e.g. to pick up new config.
kubectl rollout restart deployment/web3. Roll back
undo reverts to the previous ReplicaSet revision.
kubectl rollout undo deployment/web4. Set replicas
scale changes the desired replica count immediately.

01
Understand
Read the concept map and follow the code breakdown.
02
Reconstruct
Type the implementation, repair mistakes and work through every recall exercise.
03
Verify
Use the final check without hints; revisit weak concepts in short practice sessions.
