Wait, are we allowed to use kubectl? I was planning on just manually editing the YAML files. I hope that's not against the rules...

It's more efficient to use kubectl for these tasks, rather than manually editing YAML files.

Looks good! The key steps are creating the initial deployment, then updating the image to the new version, and finally rolling back to the previous version. Shouldn't be too difficult.

This deployment task seems straightforward. I'll use the `kubectl set image` command to perform the rolling update and `kubectl rollout undo` to rollback the deployment.
