[Question] Is there a way to get docker-gen functionallity with podman?

[aanno2]

Hello,

I have used jwilder/nginx-proxy and JrCs/docker-letsencrypt-nginx-proxy-companion a lot that both rely on docker-gen.

However, with Fedora 31 (and RHEL 8) my distribution has switched to podman (and docker is only useable if you switch back to vgroups v1). With podman, there is no unix socket /var/run/docker.sock. However, there seems an replacement for docker events: podman events (see Podman Usage Transfer).

So I wonder if there is a way to archive the functionallity of docker-gen on podman?

Kind regards,

aanno2

There is some API https://podman.io/blogs/2020/01/17/podman-new-api.html so maybe docker-gen can be adopted to use it.

Tested on podman master branch. It works using podman system service. Should be fixed in next release so of podman

docker-gen generate incorect nginx configuration in section upstream. This section is empty after execute of docker-gen in podman environment.
I will try to suppose it behavior linked with different result between docker network inspect and podman network inspect. Do somebody know how to get over this issue?

A similar discussion is happening over on the Traefik repo: traefik/traefik#5730

@jennso SELinux may be preventing your container from connecting to the Podman socket if you're using a rootless container. See here: https://bugzilla.redhat.com/show_bug.cgi?id=1495053#c2
