It is absurdly easy to fire off the docker container you mean.

Because you need to back up, verify backups, monitor availability, manage updates, manage MFA, and a zillion things.

Don't get me wrong, I work in hardcore, high tech IT for 30 years and I selfhost two dozen or so of services. It is far, very far from "absurdly easy" when you start .

Sure you can run a container on your pc, and hope for the best
