Question

You maintain a Deployment named `web` running 3 replicas. Marketing needs the app to handle a traffic spike, so you must temporarily scale it to 10 replicas without editing or reapplying the Deployment manifest and without triggering a new rollout of the pod template. Which command accomplishes this most directly?

Accepted Answer

kubectl scale deployment web --replicas=10

Answer

kubectl rollout restart deployment web --replicas=10

Answer

kubectl edit deployment web and change the image tag to force a new ReplicaSet with 10 pods

Answer

kubectl autoscale deployment web --min=10 --max=10
