I'm just imagining the poor sysadmin frantically pressing 'Ctrl+Z' in the terminal, hoping for a rollback. Kubernetes is like a genie - you gotta be really specific with your wishes!

D is just plain weird. Scaling the new Deployment to zero? That's like asking the Kubernetes equivalent of 'Have you tried turning it off and on again?'

Another option is to update the image of the Deployment to the previous version.

You can use the kubectl rollout undo command to rollback to the previous version.

C is an interesting approach, but it's a bit hacky. Updating the Service to point to the previous Deployment seems like a workaround, not a proper rollback.

Rolling back to the previous Deployment is the safest way to handle a failed blue-green deployment.

You can use Kubernetes' built-in rollback feature to easily switch back to the previous Deployment.

B is a terrible idea! Deleting container images and running pods will just create more problems. We should never manually delete production resources.
