Local server running my NAS, Technitium DNS, Jenkins + build nodes, OpenVPN, Forgejo, my Debian package mirror, the central LDAP server for auth, Lemmy, and a couple straggler services. Still working on setting up some more stuff for me and my housemates.
Running everything on an old dual Xeon box running TrueNAS, works wonders with no downtime so far!
Not sure if you got it sorted or not, but if you were following the docker-compose method documented by the devs, there were a couple hurdles I ran into. The one that may be relevant here is that at some point their
docker-compose.ymldid not expose the Lemmy backend to the Internet, and so all federation was failing. That said, I checked just now and they seem to have fixed that issue upstream. So you should be able to re-pull theirdocker-compose.ymland it should work.
