Using docker-outside-of-docker with rootless docker

[Iwan Aucamp (aucampia)]

Is there any way that docker-outside-of-docker could be made to work with rootless docker? What would be needed is a way to specify the docker.sock path [ref] but I can't see how this can easily be configurable. In other places I use DOCKER_SOCK as an environment variable to specify it, if there was some way it could read the value from there it would be great.

Could there be a pre-defined variable for the Docker socket used by VSCode to start the dev container? This would enable something like:

{
    "mounts": [
        {
            "source": "${hostDockerSocket}",
            "target": "/var/run/docker.sock",
            "type": "bind"
        }
    ]
}
