podman support for vscode:extension/ms-vscode-remote.remote-containers

[elasticdotventures]

Hi, I'm trying to build an application inside VS-Code and using podman for OCI not docker.
The extension
vscode:extension/ms-vscode-remote.remote-containers

presently as described/deployed here:
https://code.visualstudio.com/docs/remote/containers-tutorial

does not present work with podman (I don't alias docker to podman) and I'm hope to find a link to the best way to add//fix this code for my project

Hello,

I wanted to add I am also experiencing this issue and found a Stack Overflow post with the exact same problem I am facing:
https://stackoverflow.com/questions/72297060/what-could-be-the-reason-why-podman-isnt-working-on-remote-containers

As an aside, I was able to successfully develop in a container using Docker Desktop on my machine (Windows 11, WSL2 - Debian).

While I haven't seen any formal Microsoft documentation on using "Remote - Containers" extension with Podman, I followed the steps outlined here:
https://opensource.com/article/21/7/vs-code-remote-containers-podman

Thanks.

You probably need to set the Podman socket for the VS Code docker.host setting. On an Ubuntu 22.04 host this setting might be unix:///run/user/1000/podman/podman.sock.

Note however that Podman support for VS Code is a little glitchy, see #7175. (FYI I think the https://github.com/microsoft/vscode-remote-release repository is a better place for Podman questions than this one.)

I've done in the way as @jeremyn described it.

Activate rootless socket for user: systemctl --user start podman.socket
The podman socket is up and running.

$ socat - unix:///run/user/1000/podman/podman.sock
$ foo
HTTP/1.1 400 Bad Request
Content-Type: text/plain; charset=utf-8


Connection: close

400 Bad Request

VS Code settings.json (docker.host is deprecated):

{
    "docker.dockerPath": "/usr/bin/podman",
    "docker.environment": {
        "DOCKER_HOST": "unix:///run/user/1000/podman/podman.sock"
    }
}

I still get the message from the extension: "Failed to connect. Is Docker running?"

Ubuntu 22.04 x64
Podman 3.4.4
VS Code 1.74.3
VS Code Docker Extension v 1.23.3

In addition to configuring dockerPath, dockerComposePath also needs to be set. The following configuration can make it work:

{
  "dev.containers.dockerPath": "/opt/podman/bin/podman",
  "dev.containers.dockerComposePath": "/Users/xxx/.local/share/containers/podman-desktop/extensions-storage/compose/bin/docker-compose"
}

Podman Desktop will add ability to install docker-compose binary system-wide later:
