Can you roll back to a previous state using ReplicaSet?

A ReplicaSet in Kubernetes is responsible for maintaining a specified number of pod replicas, ensuring their availability. However, a ReplicaSet is not designed for managing versions or rolling back to a previous application state.

For rollback purposes, Deployment is typically used, which manages ReplicaSets and allows updates with rollback capabilities. Deployment creates new ReplicaSets during updates and can switch back to a previous ReplicaSet if needed.

Therefore, you cannot directly rollback using a ReplicaSet, but you can do so through Deployment.

Example command for rolling back a Deployment:

git kubectl rollout undo deployment/your-deployment-name

This will revert to the previous version.
