Rolling Updates and Rollbacks
Ship new versions safely with Kubernetes rolling updates, control the rollout strategy, and roll back instantly when something breaks.
Why Rolling Updates
Updating every Pod at once causes downtime. A rolling update replaces Pods gradually so the app stays available throughout the change.
Deployments Drive Updates
A Deployment owns a ReplicaSet. Changing the Pod template makes the Deployment create a new ReplicaSet and shift Pods from old to new at a controlled pace.
