Hi All, I'm new to traefik and docker.

I'm trying to run whoami example on Windows, but failed.

When i run command "docker compose up", I got the following error:

How can i use named pipe in windows? Is it supported on Windows 10 and Docker on Windows?

Thanks.

Hello @owenchen,

I am not too familiar with docker on windows, however, it appears that the volume syntax you use differs based on what windows shell you are using (bash/ps/etc):

Could you try the suggestion in there to modify the volume configuration to use the slashes that match your shell?
