Controller Revisions

Controller Revisions in Kubernetes help track the state of a controller’s configuration over time. They are used by controllers like Deployments, StatefulSets, and DaemonSets to store historical versions of their configuration so that they can easily roll back to a previous state if needed. This feature enables Kubernetes to manage and monitor the lifecycle of resources while ensuring consistency and fault tolerance.

Use Case of Controller Revisions -

• Rollback Support
• Version Control
• Automatic Management
• Failure Recovery
• Enhancing Stability
