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?

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.
