title: 'docker ps' and 'docker-compose ps' commands give different result
body: <p><strong>docker ps</strong> is giving me a different output compared to <strong>docker-compose ps</strong>.</p>
  
  <p>For example </p>
  
  <blockquote>
    <p>docker ps</p>
  </blockquote>
  
  <p>is not showing the same containers as </p>
  
  <blockquote>
    <p>docker-compose ps</p>
  </blockquote>
  
  <p>and vice-versa.</p>
  
  <p>What is the reason for this? </p>
  
  <p>I was thinking <em>docker-compose</em> is working on top of <em>docker</em>.</p>
