title: Quotes on docker-compose.yml ports make any difference?
body: <p>I don't know if there is a difference between ports with or without quotes in a <code>docker-compose.yml</code> file, can't find any good documentation.</p>
  <ul>
  <li>With quotes</li>
  </ul>
  <pre class="lang-yaml prettyprint-override"><code>ports:
    - &quot;80:80&quot;
    - &quot;443:443&quot;
  </code></pre>
  <ul>
  <li>Without quotes</li>
  </ul>
  <pre class="lang-yaml prettyprint-override"><code>ports:
    - 80:80
    - 443:443
  </code></pre>
  <p>I see no difference when I run it</p>
