I finally managed to selfhost Lemmy and Matrix, now it is time to also get a selfhosted Mastodon instance up. A few questions before I start:

I did some research into the topic and it seems that Mastodon doesn’t like to run behind an existing reverse proxy and there are quite a few tweaks necessary to get it running - can someone confirm this? Or is this something easily set up?

I’m currently leaning to run it on a dedicated VPS (due to the issue above and also because it seems to need quite a bit of disk space) - this opens up to do a non-docker installation and follow the official install path. Do you think this will make it easier to keep it updated to new releases in the future?

If going with a docker install there seem to be quite a few problems with updating (at least a lot of threads discussing failed update procedures sprung up when I googles “mastodon docker update”) - can someone confirm? Are there easy to follow guides for a docker based update routine?

Right now it seems the easiest would be to run on a dedicated server, follow the native installation procedure and use the templates provided for nginx, certbot, … thoughts?

    Is there a good guide for Mastodon in Docker? I’ve followed a few but they all get stuck at various points.

      You need to actually piece together those few to come up with one cohesive working instance. I can share with you the docker-compose.yml file that worked for me, if that will help.
