Unfortunately I haven’t been able to figure this out, I was able to write a script for Mastodon that automated the process of dumping the database, copying the system folder and so on, I was able to restore a test backup I made successfully as well. I only say that to indicate that I have at least some familiarity with the shell, but not much 😁 In the case of Mastodon it’s running on “bare metal” so to speak rather than Docker, so this is probably much easier for someone who is familiar with Docker!

Thanks, that should be simple to figure out if it’s just one step, although I’ve never dumped a database from a Docker image before…I’ll have to do some searching and see if I can figure it out!
