title: Error starting userland proxy: listen tcp4 0.0.0.0:80: bind: address already in use
body: <p>I am trying  to follow a tutorial for Docker beginners (<a href="https://docs.docker.com/get-started/" rel="nofollow noreferrer">https://docs.docker.com/get-started/</a>)</p>
  <p>When I try to run this command:
  <code>$ docker run -d -p 80:80 docker/getting-started </code></p>
  <p>I get this Error:</p>
  <p><code>docker: Error response from daemon: driver failed programming external connectivity on endpoint suspicious_murdock (863f389a032ea76d187c4387701b9eb0b6d4de4d0a9ed414616fa6b4715346ab): Error starting userland proxy: listen tcp4 0.0.0.0:80: bind: address already in use. </code></p>
  <p>I tried removing all the dockers <code>docker rm -fv $(docker ps -aq) </code> but it did nothing.</p>
  <p>What can I do?</p>
