title: Remove a named volume with docker-compose?
body: <p>If I have a docker-compose file like:</p>
  <pre class="lang-yml prettyprint-override"><code>version: &quot;3&quot;
  services:
    postgres:
      image: postgres:9.4
      volumes:
        - db-data:/var/lib/db
  volumes:
    db-data:
  </code></pre>
  <p>... then doing <code>docker-compose up</code> creates a named volume for <code>db-data</code>. Is there a way to remove this volume via <code>docker-compose</code>? If it were an anonymous volume, then <code>docker-compose rm -v postgres</code> would do the trick. But as it stands, I don't know how to remove the <code>db-data</code> volume without reverting to <code>docker</code> commands. It feels like this should be possible from within the <code>docker-compose</code> CLI. Am I missing something?</p>
