title: docker container named dreamy_ritchie?
body: <p>I am learning how to use docker, I was a able to run multiple containers and everything is working fine, but there is one issue, when I stop all the containers, and then run: docker ps,
  it doesn't show anything, but when I run: docker ps -a, it shows this:</p>
  <pre><code>bc39a16a9ac6   1c5b0a98ac9d  &quot;/bin/sh -c 'chmod -…&quot;  .... dreamy_ritchie
  </code></pre>
  <p>it is so strange, the container <strong>dreamy_ritchie</strong>, I didn't create that one, is it a virus? or is a docker internal container? thanks</p>
