podman support?

[igagis]

I'm thinking to install github-act-runner on my riscv64 boards which, AFAIK, has no official docker binary build. But, there is podman which can easily be installed from debian repo.

So, I'm wondering, will github-act-runner transparently use podman instead of docker? If not, would be great if such support is added. Thanks!

No it won't do that transparently, as nektos/act doesn't really support podman and directly uses docker api via it's go api library.

You need to enable the podman.sock, if you would relocate /var/run/podman/podman.sock to /var/run/docker.sock then it works transparently. (a symlink itself might behave diffently, due to bind mounts of that location)

Most would work not transparently by setting env DOCKER_HOST=unix:///var/run/podman/podman.sock in the service.
I guess your old script has trouble with adding custom envs, but not exactly shure.
The newer svc command has .env support to set such stuff, but seems like the sh shim of the deb's hides it.

Strange thing is that when I did chmod 777 it just worked. But when I used approach with systrmctl --user start podman it started giving this volume mount error

--user start rootless podman, rootful podman have more permission and might cause the difference

You might be able to also create a custom docker group, and chown the rootful podman socket so it might be able to mimic docket in this aspect.

Docker is by default always rootful instead of rootless

If I do sudo touch /var/run/docker.sock then it starts to work.
Now, the question, @ChristopherHX can you make the change to act which would allow to avoid creating this dummy docker.sock?

I'm planning to make a change to the systemd scripts to allow configuring runner to use podman instead of docker. And in combination with the change in act it could provide good user experience.

I actually went ahead and made a pull request #179 for script side changes

[igagis]

All needed changes are already implemented and merged, new runner version released.
I have already tried it with podman, seems working. Yay! Thanks @ChristopherHX and @mochja !
