I'm considering using Hetzner (or equivalent) for our CI setup with Github Actions custom runners. Right now we're on CircleCI and it costs an arm and a leg. Does anyone have experience to share with that kind of setup? What's the maintenance like?
Short answer it depends on your needs and you comfort level with server management. But generally I would say a server running something like Jenkins or similar is not that taxing on the maintenance budget. It does have some up-front cost in getting everything configured and running as you like but after that it is fairly easy to maintain. I usually automate the provisioning as much as possible both for the self-documenting aspect but also to make it easier to repave the system or spin up additional nodes as needed.
