Either you run the RP in the VPS and point to the ips on your server or you run it on the server and access it like you are accessing Jellyfin.

Easiest option is a container with Nginx proxy manager (imo) with NPM you can get free let’s encrypt certs, but be aware, in case you want automated certificates, NPM will need to run on the machine pointed to by the DNS (in your case, your VPS I guess)

Proxmox for the the hosts, Debian cloud imagen for the VMs and docker inside

Yes, but doesn’t that also apply for a machine running bare git?

Not containers also adds some challenges with posibly having dependecies problems. I’d say running bare git is not a lot easier than having a container with say forgejo.

Is running a docker container a lot of overhead?

Ernestly asking, since my opinion is skewed cause im use to running containers.

Most tutorials only want clicks and for it to “work”…

Pretty frustrating.
