Helm migration hooks under GitOps
WHAT IT TESTS: Helm hooks plus GitOps tension. OUTLINE: use a pre-upgrade hook Job with weights and delete policy; the challenge is GitOps tools render statically and reconcile, conflicting with Helm's imperative hook lifecycle. RED FLAG: ignoring idempotency.
WHAT IT TESTS: whether you can sequence migrations and foresee GitOps friction. ANSWER OUTLINE: define a Kubernetes Job annotated as a Helm pre-upgrade hook with a hook-weight for ordering and a hook-delete-policy for cleanup, so it runs before new pods roll out. The challenge: GitOps controllers like Argo CD render the chart and reconcile declaratively, so Helm's imperative hook lifecycle does not map cleanly; tools translate hooks to sync hooks or PreSync phases, and migrations must be idempotent.
