title: How can I reduce space used by Docker in MacOS?
body: <p>I am running very low on disk space (only 11G free of a 512G SSD drive). I need some more space for my development work.</p>
  
  <p>One of the big files identified by the app <code>CleanMyMac X</code> is this one: <code>/Users/antkong/Library/Containers/com.docker.docker/Data/vms/0/data/Docker.raw</code></p>

  <p>I have done a <code>docker images</code> and they cannot add up to 64G</p>
  
  <pre><code>$ docker images
