I think using --rm is super handy for cleanup.

I feel like I might have mixed up the flags for the image and the command. Should we use `--image` before the `--restart` option?

I remember practicing a similar question where we had to create a pod that runs a simple script. I think using `-it` is optional here since we're not interacting with it.

I'm a bit unsure about the exact syntax for the `kubectl run` command. Did we cover if we need to specify the pod name?

I think the command should definitely include the `--rm` flag to ensure the pod gets deleted after it finishes.

Alright, let me give this a try. I'm feeling pretty confident I can get this working on the first try.

I've got this! I'll use the `--rm` flag to have the pod deleted as soon as the command completes. And the `--restart=Never` option to ensure it doesn't try to restart.

Wait, how do I make the pod delete itself automatically when it's done? I'm a bit confused on that part.

Okay, let me think this through. I need to create a pod that runs a simple echo command and then deletes itself. Shouldn't be too hard.

I feel like I've seen a question like this before, and I think the INTERSECTION keyword is the most standard way to get the intersection across different SQL dialects.

I'm feeling pretty confident about this one. The wording of the question is straightforward, and the options seem clear. I'll review them one more time to double-check, but I think I've got a good handle on the solution.

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.

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.
