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 been trying to get docker swarm running across my 4 rpi's, but traefik hasn't been able to discover services (can find them on the same node if the network is a bridge, can't find anything with overlay network) which has been frustrating to try to figure out the problem. That said, here is what I plan to host on the swarm:
traefik
grocy
nextcloud
vaultwarden
plex
nginx (portfolio website that I currently just have on GitHub pages)
lemmy instance (for some of you beautiful bastards)
readarr, sonarr, readarr, lidarr, prowlarr, sabnzb, and qbittorrent
I run k3s on a similar setup, 4x rpi4 and 2x Intel Atom mini PCs. Obviously different software with different goals, but was remarkably simple despite the heterogenous platform.
