Rollback

Reverting a system to a previous known-good version after a failed or problematic change.

Definition

Rollbacks can redeploy a previous artifact, swap back traffic, or revert a Git commit in GitOps. Database schema changes complicate rollback, so they should be backward-compatible.

Example

kubectl rollout undo deployment/web reverts to the prior ReplicaSet.

Exam tip

Automated rollback triggered by CloudWatch alarms in CodeDeploy is a common AWS DevOps exam answer.
