I have my own home-server and it's not really a problem maintaining it as I've been through a steep learning curve. Now I have a friend who has an ancient Synology and it is always causing terrible problems for him.

If I were to set up a little server for him with docker services running things like immich and syncthing etc, would this be set and forget enough to not cause problems for him? Ideally he wants his own cloud so relatives can store and share files, photos, and possibly movies too. He isn't the most tech savvy, but he knows his way around Windows and PC's generally. He doesn't live that close so I can't be at his if anything went a little pear-shaped. I could however ssh into it at least.

Is this feasible or practicable? Or would he have to learn Linux and Docker et al.?
