Steps to Reproduce:

1. use podman instead of docker
2. open a project
3. run command "Dev Container: Open folder in containers"
4. command runs failed

Does this issue occur when you try this locally?: Yes
Does this issue occur when you try this locally and all extensions are disabled?: No

according to the log, dev container will try to mount the wayland-0 of wlsg to container, in which it uses the UNC path but podman dont support that

[cnjn]

here is a discuss about UNC path, #7978 (comment)

but unfortunally, This method does not work on my computer

not matter i use wsl2 or windows, dev container cant open the folder in container with podman

[mmalyska]

I have the same problem. When I remove this mount, then podman(docker) works.

[cnjn]

@mmalyska

but its added automaticully, i have never added this arg.
and i dont konw how to remove this mount 😢

[chrmarti]

Will add a user setting to turn the automatic mounting off.

[connor4312]

Looks like we still need a release for the extension

[chrmarti]

Available in Dev Containers 0.287.0-pre-release.

I tried to do this with the new option dev.containers.mountWaylandSocket: false, but got the following error:

The podman run command shows no mount option for the Wayland socket, so the setting is applied. The error is about Podman not supporting to mount the UNC path for the workspace folder. This seems to be an issue with the Podman setup, please open a new issue if you think this is a problem with the Dev Containers extension.

Closing again for verification as this is a different problem. Thanks.

[connor4312]

I can run the same podman containers elsewhere (barring the minor bug I linked above), just not in the UNC path. I'll open a new issue for that.

Untagging so someone else can try verifying

[chrmarti]

@connor4312 The issue here is with a workspace folder at a non-UNC path. Podman fails on the automatically added mount point for the Wayland socket which is only added when WAYLAND_DISPLAY is set in WSL. The setting is to turn the automatic mount point off completely. If I understand you correctly, you have everything working, you just need to use a non-UNC workspace folder. Could you give it another try? Thanks!

[connor4312]

Ahh, gotcha! That works. Sorry I misunderstood.
