I run jellyfin, plex, mattermost, peertube, minecraft, all under one host. Never had anything conflict and just upgrade the rpms. Some of them use the same postgres database. Thats how I prefer to do things. I will use docker if absolutely forced, I know how, understand its easier to deploy etc. but I would rather it be the choice of the user instead of the software. Or if not rpm let me get in the source and run it.
