Question

Your team uses Google Cloud Deploy to deliver a GKE microservice through dev, staging, and prod targets. A release was promoted to prod, but on-call engineers report elevated error rates minutes after the rollout completed. You need to restore the previously running, healthy version in prod as quickly as possible while keeping a clear audit trail in the delivery pipeline. What should you do?

Accepted Answer

Run a Cloud Deploy rollback on the prod target, which creates a new rollout that redeploys the last successfully deployed release.

Answer

Delete the failed release in Cloud Deploy so the pipeline automatically reverts the prod target to its prior state.

Answer

Use kubectl to manually apply the previous Deployment manifest directly to the prod GKE cluster.

Answer

Re-run the original Cloud Build trigger with the previous commit SHA to rebuild and redeploy the old image.
