Config option to set default host IP to 127.0.0.1 instead of 0.0.0.0

[lng-sys]

Hi, when I use the option -p 80:80 to publish ports without specifying the host IP I would like Podman to assume 0.0.0.0 when running on servers and 127.0.0.1 when running on Linux desktop.

On Ubuntu 2x.04 LTS and Fedora 4x I get 0.0.0.0 when I don't specify anything (I check using podman ps) on rootless Podman. So I want to configure desktop installations to use 127.0.0.1.

I can achieve this with Docker by setting:

{
    "ip" : "127.0.0.1"
}

in /etc/docker/daemon.json.

I wasn't able to find the equivalent for Podman. I am expecting an option in containers.conf.

Notice that I want to be able to overwrite the IP when needed by using -p 0.0.0.0:80:80, so the option I am looking for must only overwrite what Podman assumes when no IP is specified (-p 80:80).

Thank you in advance for any hint.

There is no such option today but adding one sounds like a reasonable feature request.

@Luap99 thank you, should I open a issue/FR and close this discussion?

yes that would be best
