Question

You need to apply several changes to a running Deployment named 'web': update the container image, add a new environment variable, and increase the CPU request. You want to make all these edits without triggering a separate rolling update for each change, then roll them all out together as a single revision. Which sequence of commands achieves this?

Accepted Answer

kubectl rollout pause deployment/web, apply the image/env/resource changes, then kubectl rollout resume deployment/web

Answer

kubectl rollout undo deployment/web, apply all changes, then kubectl rollout restart deployment/web

Answer

kubectl scale deployment/web --replicas=0, apply all changes, then kubectl scale deployment/web --replicas=3

Answer

kubectl annotate deployment/web kubernetes.io/change-cause, apply all changes, then kubectl rollout status deployment/web
