Question

Your team packages a web application as a Helm chart. During a `helm upgrade`, a database schema migration Job must run and complete successfully before the new application Deployment pods are rolled out. If the migration fails, the upgrade should not proceed. Which Helm feature lets you order this migration Job to execute at the correct point in the release lifecycle?

Accepted Answer

Define the Job as a Helm hook using the annotation helm.sh/hook: pre-upgrade

Answer

Set the Job's restartPolicy to OnFailure so Helm waits for it automatically

Answer

Add the Job to a subchart so it renders before the parent chart's Deployment

Answer

Increase the Deployment's initialDelaySeconds so the Job finishes first
