Current insider builds of Windows have support for mounting individual named pipe servers from the host to the guest. This allows, for example, exposing the docker engine's named pipe to a container. This change allows the user to request such a mount via the normal bind mount syntax in the CLI: docker run -v \\.\pipe\docker_engine:\\.\pipe\docker_engine <args> Signed-off-by: John Starks <jostarks@microsoft.com> Upstream-commit: 54354db850664783918a1fc9d208bcfcf47c28e2 Component: engine
