Yes, that's correct. The --rm flag ensures the pod is deleted once it's completed.

I would use the kubectl run command with the --rm flag to delete the pod automatically.

Ha! I bet the exam proctors will be confused when they see the pod vanish like a magic trick. Got to keep them on their toes!

Wait, so it just disappears after saying 'hello world'? That's kind of anticlimactic, don't you think?

I wonder if the pod will say 'goodbye world' before it disappears. You know, for balance and symmetry.

That command will create a pod that echoes 'hello world' and then deletes itself.
