title: How to add volume to Docker but exclude files
body: <p>I would like to mount everything inside my current directory, except 2 files.
  log4j.properties and datanucleus.properties</p>
  
  <p>myapp/config:/root/myapp/config</p>
  
  <p>My directory structure is as follows</p>
  
  <p>config</p>
  
  <p>subdir1</p>
  
  <p>subdir2</p>
  
  <p>subdir3</p>
  
  <p>log4j.properties</p>
  
  <p>datanucleus.properties</p>
  
  <p>I currently have to manually mount all the paths as following: </p>
  
  <p>myapp/config/subdir1:/root/myapp/config/subdir1 </p>
  
  <p>myapp/config/subdir2:/root/myapp/config/subdir2 </p>
  
  <p>myapp/config/subdir3:/root/myapp/config/subdir3</p>
  
  <p>Is there any option to mount everything in a directory and exclude few files</p>
  
  <p>Thanks for your clarification</p>
