Step-by-Step Guide to Rollback a Deployment

1. List Deployments:
   First, list all the Deployments in your cluster to identify the one you want to rollback:

   bash Copy

   kubectl get deployments

   This command will display the status of all Deployments in your cluster.

2. Check Revision History:
   Obtain the revision history of the specific Deployment you want to rollback. Replace <deployment_name> with the name of your Deployment:

   bash Copy

   kubectl rollout history deployment/<deployment_name>

   This command will show the revision history, including the change causes for each revision.

3. Rollback to a Specific Revision:
   To rollback to a specific revision, use the following command. Replace <revision_number> with the desired revision number:

   bash Copy

   kubectl rollout undo deployment/<deployment_name> --to-revision=<revision_number>

   This command will rollback the Deployment to the specified revision.

4. Verify Rollback:
   After performing the rollback, verify that it was successful by checking the status of the Deployment:

   bash Copy

   kubectl rollout status deployment/<deployment_name>

   If the rollback was successful, you should see a message indicating a successful rollout.

5. Check Deployment Details:
   Optionally, you can describe the Deployment to get more details about its current state:

   bash Copy

   kubectl describe deployment/<deployment_name>
