I'm running Proxmox on a mini PC. On Proxmox, I have AdGuard, NPMPlus, and Homepage LXCs, as well as a VM for Docker, with Jellyseerr, Jellyfin, Radarr, Sonarr, Notifiarr, and qBittorrent containers.
I haven't really done much with NPM or AdGuard yet. But all the other services are set up and communicating with each other - so I can request media via my Discord server, or Jellyseerr's web ui, and it'll go through the right apps and add them to Jellyfin for me to watch. All the media, configs, backups, etc., are all stored on my NAS, since I've got a few TB of space on there.
I also realised before going to sleep that while it feels like I've been working on it for a straight week, I only actually started setting it up on the 5th.
This is the latest screenshot I have of my dashboard, still adding stuff to it and tweaking it.
EDIT: Oh yeah, and Prowlarr and FlareSolverr aswell, I keep forgetting about them because they're very backend.
