I definitely practiced rolling back deployments, but I can't remember if I need to specify the revision number or just the previous version.

I’m a bit confused about how to specify the version during the rolling update. Was it in the same command or a separate one?

This question feels similar to the practice we did on Kubernetes deployments last week. I hope I can recall the commands correctly.

I think I remember how to create a deployment, but I'm not entirely sure about the exact syntax for the rolling update.
