title: Volume path or Mount in Windows container
body: <p><strong>Description</strong><br>
  I got error "Error response from daemon: invalid mount config for type "volume": invalid mount path" in Windows Container </p>
  
  <p><strong>Steps to reproduce the issue:</strong><br>
    1. DockerFile  </p>
  
  <pre><code>FROM microsoft/aspnetcore-build AS base
  WORKDIR /app
  
  ENTRYPOINT [ "dotnet", "Test.dll" ]
  </code></pre>
  
  <ol start="2">
  <li>Run command <code>docker build -t docker-vol .</code>   </li>
  <li>Run Command <code>docker run -it -p 8001:80 -v D:\Projects\Docker\publish:c:/app --name docker-vol-test docker-vol</code> (This works)</li>
  <li>Run Command <code>docker run -it -p 8001:80 --mount "source=D:\Projects\Docker\publish,target=c:/app" --name docker-vol-test docker-vol</code> This fails with <code>Error response from daemon: invalid mount config for type "volume": invalid volume name</code></li>
  </ol>
  
  <p>I am wondering how to work with --mount and whether it is possible to use relative path instead of absolute path with -v?</p>
