title: Override docker not working
body: <p>I change ports in file 'docker-compose.override.yml' and run docker (docker-compose up). Docker isn't seeing my changes (ports) in override.</p>
  
  <p>Content override:</p>
  
  <pre><code>version: '2'
  
  services:
      nginx:
          ports:
              - 87:80
  </code></pre>
  
  <p>Why docker isn't changing the port?</p>
