Hi there,
I would like to host my own Synapse server, but I am not sure where to start.
I would like to be able to use Nginx Proxy Manager as the reverse proxy and I’ve read that you can use example.eu for the username, while actually using a subdomain like matrix.example.eu?
Is there some good documentation out there and what would people recommend? I would like to run it in a container on Proxmox, but Docker could also be an option?
Synapse has become open-core and the possible alternatives are either abandoned or are currently in a really unclear state. And due to how Matrix federation works, it is quite difficult to change anything later and if you are unhappy with the setup you have basically burned a domain and need to start fresh on another. If you just want a chat server I would rather suggest to set up a XMPP server with a Slidge.im Matrix bridge.
That said: there are easy to use official Docker containers for Synapse, and you just need a redirect in your reverse-proxy for some sub-directories to put it on the same domain than something else. There are also some other, more complex ways to do it, but just redirecting the subdirectories is the easiest.
That would regio explain with there are so few matrix servers out there compared to Lemmy or Mastodon.
