I wrote something similar that's custom for my personal infrastructure: https://github.com/sumdog/bee2 https://github.com/sumdog/bee2 There are some blog posts in the README that go into how I built a lot of it. A lot of it is specialized for me though. I have a ton of rspec/tests but I don't have a real config schema or entirely useful error messages. I might add some in the future. Looking at the list in this, I'd advice against nextCloud(ownCloud). I recently setup their official Docker containers and the web piece works alright, but their F-droid app continually crashes and I had to uninstall it and the nextcloud-client in Gentoo's package manager segfaults at home and refused to build at work. I've read other stories of data loss with nextcloud. It might be better now but my initial experiences made me use syncthing. Syncthing does use relays if you're behind a NAT, but if you have openvpn setup, you can also force it to use a direct IP address as well. If you're thinking if self hosting and have the time, I'd suggest building it yourself; borrowing (and properly accrediting/licensing) other open source projects, their ansible scripts and containers and such. You learn a whole lot about why this tooling is so complex.
