I have DietPi running on an RPi 4 with 4GB RAM.
Everything here is hosted in docker containers:
- Portainer (docker management)
- Nginx Proxy Manager (for reverse proxy)
- Nextcloud (file storage + calendar)
- Kanboard (task management + kanban board)
- Homepage
- Transmission (behind VPN with Flood web frontend)
- Jellyfin media server
- A Discord bot for my server
- Watchman, my RSS feed to Kindle setup (https://github.com/andrwcnln/watchman)
I’ve probably forgotten some things but that’s the main bulk of it. Can’t recommend DietPi enough if you are looking for a super lightweight OS for you Pi server, has been perfect for me so far. Here are some things I am looking to host in the future too:
- ntfy (for push notifications)
- Apache server for my websites
- Pi-hole
- Plausible (a replacement for Google analytics for websites)
- Vaultwarden
I’d really recommend docker/podman etc. if you are going to host more, especially with portainer. makes things a lot easier to manage when you have lots of services hosted.
then again I’m not sure you could get much more running on an RPi 2. how does it hold up in general with the stuff you have so far?
