@jwildeboer I tested Forgejo the last two days at home. First as Container (Podman), but Git over SSH is a problem, as long as you don't want to use a different port for it. So I spun up a KVM Machine with a dedicated IP, works well as expected. Though I had to install the binary by downloading it manually and had to take care of the service untit running.
The runner has been installed the same way, but as a different user. One problem, to get podman via user socket running, aka rootless 1/3
