Podman: WSL2 suppport

[glenfordwilliams]

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

/kind bug

Description

While WSL2 now uses a vm it does not support systemd well out of the box which results in failed events when using journalctl.

Steps to reproduce the issue:

1. podman --log-level debug run -it docker.io/library/alpine sh

change the event logger in your libpod.conf to file.

Can we build a podman specific for WSL2?

[baude]

sure but i dont think it is worth it. to use wsl2, you "install" a linux distro and then use apt or whatever to install podman. it would mean the distro would have to build and distribute it

Sir, can I achieve this in centos or arch from yuk7 https://github.com/yuk7/ArchWSL

I've been trying but no success, do you recommend other centos distribution?.

@baude is there another way to achieve this? the latest podman version doesn't create libpod.conf anymore https://github.com/containers/podman/issues/7509

I thought libpod.conf was renamed to containers.conf. Does Podman work for you in WSL2 nonetheless?

[rhatdan]

Yes containers.conf is the way to go.

Yes containers.conf is the way to go.

Hi @rhatdan Thanks for the information provided. I was following your guide until the "Rootless configuration file changes". Podman wasn't working and I was getting crazy looking for the libpod.conf until I found thir thread. Would be awesome if you could update the post :)
Keep the awesome work, thanks

I made an automation covering the blog article to install Podman on WSL using ansible-pull. Supported distros are Debian, Ubuntu and Arch Linux. Arch is untested but it should work.
