title: Is docker-machine required on linux?
body: <p>I am running a <code>Windows7</code> (64-bit) machine having <code>vmplayer</code>, which hosts <code>Fedora 25</code>. </p>
  
  <p>I have installed <code>docker CE</code> on it and my examples till now have worked fine. </p>
  
  <p>The issue is when trying to run <code>docker-machine</code> examples. As per my understanding, it is required to create hosts for docker. </p>
  
  <ul>
  <li><p>While it makes sense to have it on <code>Windows</code> and <code>Mac</code> but do I need it on <code>Linux</code>? </p></li>
  <li><p>What even adds to confusion is, how come all the examples I tried till now have worked fine?</p></li>
  <li><p>Another point is, if <code>docker-machine</code> is not part of <code>Linux</code> docker distribution; then how do we create multiple docker hosts on <code>Linux</code>?</p></li>
  </ul>
