I have 2 pi4 4GB boards and was waiting forever to get a third to run RAFT based services across.
I gave up last year and bought 3 chinese boards at $60/ea with 2x 2.5Gb Ethernet each, emmc, and a m.2 slot - and they run at half the temp of the pi4 boards.
I never needed the wifi/bt and form-factor the pi boards offered anyway - really no reason to stay as long as you can find software that boots on other boards.
I run drone.io with gitea, it’s nice, doesn’t do much when it’s not working.
Gitea added their own CI tooling that is configured like GitHub actions as well - I haven’t tried it yet though.
Ceph (rbd,s3) on 4 poweredges.
Nomad, Consul servers running in a 3 node raft on some ARM SBCs.
Nomad clients on 2 poweredges and 3 arm SBCs running:
And that is just in the server room - I also have more like the 3d printer and CNC machine controllers etc.
Ok that’s pretty cool (good bot)
