Remote Docker: DooD devcontainer mount paths are not converted from Windows to Linux/WSL2 format

[FloSch62]

What happened?
When using a Docker-out-of-Docker (DooD) devcontainer configuration on Windows with WSL2, I'm getting a mount path error. The error occurs because DevPod is using Windows-style paths instead of WSL2-compatible paths.

Error message:

[18:05:56] info docker: Error response from daemon: invalid mount config for type "bind": invalid mount path: 'C:/Users/Flo/.devpod/agent/contexts/default/workspaces/srl-snmp-framework-lab/content' mount path must be absolute.

What did you expect to happen instead?
The path should be automatically converted to WSL2 format (e.g., /mnt/c/Users/Flo/.devpod/agent/contexts/default/workspaces/srl-snmp-framework-lab/) when DevPod interfaces with the Docker daemon running in WSL2.

How can we reproduce the bug? (as minimally and precisely as possible)

• Set up Windows with WSL2 install Docker and expose it
• Use Docker CLI from https://download.docker.com/win/static/stable/x86_64/docker-27.3.1.zip
• Configure Docker host as tcp://localhost:2375
• Docker Path: C:\Program Files\Docker\cli\docker\docker.exe
• Try to run a DooD devcontainer with this configuration:

My devcontainer.json:

{
    "image": "ghcr.io/srl-labs/containerlab/devcontainer-dood-slim:0.60.0",
    "runArgs": [
        "--network=host",
        "--pid=host",
        "--privileged"
    ],
    "mounts": [
        "type=bind,src=/run/docker/netns,dst=/run/docker/netns",
        "type=bind,src=/var/lib/docker,dst=/var/lib/docker",
        "type=bind,src=/lib/modules,dst=/lib/modules"
    ],
    "workspaceFolder": "${localWorkspaceFolder}",
    "workspaceMount": "source=${localWorkspaceFolder},target=${localWorkspaceFolder},type=bind,consistency=cached"
}

Local Environment:

• DevPod Version: 0.6.4
• Operating System: windows
• ARCH of the OS: x86_64

DevPod Provider:

• Local/remote provider: docker

Anything else we need to know?

• Docker Desktop is not an option because of license reasons
• Rancher Desktop was not working as well as they expose docker also via a WSL
• Docker Host: tcp://localhost:2375
• Docker Path: C:\Program Files\Docker\cli\docker\docker.exe
• Docker-in-Docker (DinD) devcontainers work fine
• Only experiencing issues with Docker-out-of-Docker (DooD) configurations
• The Docker daemon is running in WSL2, exposed to Windows
