It is nice that you got it running, but when everything you end up doing is running services in low ports or needing specific IP address in different networks, rootless podman is just a PITA.
In my case I have one pihole running on a docker container and another one that runs directly on a VM.
Someone said before “what’s the point of running in a container”… Well, there really isn’t any measurable overhead and you have the benefit of having a very portable configuration.
I do think the compromises one has to go through for podman rootless are not worth in this case, for me, not even the rootful worked properly (a few years ago), but this is a nice walkthrough for people wanting to understand more.
