I’ve recently joined the beta program for Docker on Windows (now based on Hyper-V).

I wanted to keep my current config using msysGit but got weird errors when executing Docker commands from msysGit: https://forums.docker.com/t/weird-error-under-git-bash-msys-solved/9210

I could fix the issue by installing a newer version of msysGit with support for the MSYS_NO_PATHCONV environment variable. With that installed, I then changed my docker alias to a better approach:

docker()
{
    export MSYS_NO_PATHCONV=1
    ("$DOCKER_HOME/docker.exe" "$@")
    export MSYS_NO_PATHCONV=0
}

Hope this helps!
