During a Helm upgrade of a billing chart, a one-shot migrate Job runs before the new Deployment pods start. At awareness depth, what Helm feature typically drives that Job?
Select an answer to reveal the explanation.
Short Explanation
Hooks are like stage cues in a play: before the main actors walk on, a short scene (your migrate Job) runs. Charts wire those cues so upgrades do not forget the migration step.
Full Explanation
Helm hooks annotate resources to run at lifecycle points such as pre-install or pre-upgrade. Charts commonly use a Job hook for schema migrations so they execute as part of the release, not as an unrelated side script. ReplicaSets, Ingress TLS, and kubectl wait do not implement chart hook semantics.
