Podman from WSL not found

[carlcamilleri]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

Environment setup:

• .NET Aspire app code checked out in the default WSL distribution
• Podman installed as a separate WSL distribution
• ~/.bash_aliases contains alias podman='podman-remote-static-linux_amd64'
• In the WSL terminal, running podman images runs successfully

Error encountered: : Container runtime 'podman' could not be found. The error from the container runtime check was: exec: "podman": executable file not found in $PATH

Expected Behavior

No response

Steps To Reproduce

Exceptions (if any)

.NET Version info

Anything else?

Looks similar to dotnet/aspire#5571. Unable to find an executable on the path. I wonder if this is to do with where the apphost was launched from.

Thank you! Adding some more context of the terminal environment below, just in case it helps.

I have also verified that copying /usr/local/bin/podman-remote-static-linux_amd64 to /usr/local/bin/podman allows the Aspire application to run fine

Unfortanetly you can't alias the command to be resovled correctly, podman will need to be part of the environment path.

[carlcamilleri]

At the risk of being a pain, this means Aspire is unusable under the Podman installation instructions at https://podman-desktop.io/docs/podman/accessing-podman-from-another-wsl-instance

I’m guessing this is not an isolated case, so if it will not be supported I guess it needs to be documented

[davidfowl]

Let's add this to the docs for now.

Also it would be nice if you could update the tasks for the Applied Skill https://learn.microsoft.com/en-us/credentials/applied-skills/build-distributed-apps-with-dotnet-aspire/ which requires podman
