Hi! I have installed Rancher Desktop, and clicked on the option:

Expose Rancher Desktop's Kubernetes configuration and Docker socket to Windows Subsystem for Linux (WSL) distros

But I have to run as root, or else I get :

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "<http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json>": dial unix /var/run/docker.sock: connect: permission denied

Because

$ ls -l /var/run/docker.sock
srwxr-xr-x 1 root root 0 Dec 12 13:46 /var/run/docker.sock

I'd like to run with some group membership, so I can run docker cli as a normal user

Can you please try the solution provided in this FAQ ?
