podman machine inspect should report IP address

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind feature

Description

I am using Podman 4.3.0 on Windows 11 WSL2, and attempting to contact the podman machine from another Linux distribution.

The default podman system connection list SSH URI contains localhost as host name, and this does not resolve properly from within another WSL distro.

I have worked around this by obtaining the IP address of the podman machine, but as this changes every time the machine is started (and ifconfig is unavailable) this is klunky.

Steps to reproduce the issue:

1. podman machine start

2. podman machine inspect

3. Look for IP address in the JSON output.

Describe the results you received:

• No Ip address in the JSON output.

Describe the results you expected:

An IP address so I can construct a CONTAINER_HOST URL that works from within a WSL distro.

Additional information you deem important (e.g. issue happens only occasionally):

Package info (e.g. output of rpm -q podman or apt list podman or brew info podman):

Installed from https://github.com/containers/podman/releases/latest

Have you tested with the latest version of Podman and have you checked the Podman Troubleshooting Guide? (https://github.com/containers/podman/blob/main/troubleshooting.md)

Yes

Additional environment details (AWS, VirtualBox, physical, etc.):

Host is a Windows 11 laptop with WSL2. Client is an Ubuntu 22.04 WSL distribution.

@n1hility I recall hearing that there is a shared space in the WSL VM that all WSL distros can access where we can put the Podman socket to avoid this?

[asgeirn]

You could probably use /mnt/wsl for this. I tried writing a file from podman-machine, and it's readable within the Ubuntu distro.

[asgeirn]

Yup, that worked - but requires that the UIDs match.

In podman-machine:

podman system service --time=0 unix:///mnt/wsl/podman.sock

In Ubuntu machine:

podman --url unix:///mnt/wsl/podman.sock version
