title: Docker compose, it is possible to mount a folder inside an already mounted volume?
body: <p>When using compose for development I have my app mounted inside /var/www/html with this: </p>
  
  <pre class="lang-yaml prettyprint-override"><code>volumes:
  - ./app:/var/www/html
  </code></pre>
  
  <p>My local copy needs all the images that are in the production website, that are quite a lot so I don't want to store them in my tiny ssd but in a big extenal disk.</p>
  
  <p>So my images are located in my /media/storage/bigdisk/images.</p>
  
  <p>it is possible to mount this location inside the already mounted /var/www/html?</p>
  
  <p>This way doesn't seem to work:</p>
  
  <pre class="lang-yaml prettyprint-override"><code>volumes:
    - ./app:/var/www/html
    - /media/storage/bigdisk/images:/var/www/html/images
  </code></pre>
