A simple question to this community, what are you self-hosting? It's probably fun to hear from each-other what services we are running.
Please mention at least the service (e.g. e-mail) and the software (e.g. postfix). Extra bonus points for also mentioning the OS and/or hardware (e.g. Linux Distribution, raspberry pi, etc) you are running on.
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)
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?
