Rolling Update - CI/CD Glossary Definition

A rolling update replaces pods incrementally, bringing up new ones and tearing down old ones a few at a time so the service stays available throughout. maxSurge and maxUnavailable control the pace.

Rollback

If a rollout stalls on failing readiness probes, kubectl rollout undo reverts to the previous ReplicaSet. CD pipelines often run kubectl rollout status to gate on success.
