title: Docker-CE or docker on CentOS
body: <p>I have a group of CentOS 7 machines that I had previously installed 'docker'; however, I'm finding that there's a repo with newer versions for CentOS with the docker repo added:  'docker-ce'.</p>
  <pre><code>Name        : docker
  Arch        : x86_64
  Epoch       : 2
  Version     : 1.12.6
  Release     : 68.gitec8512b.el7.centos
  Size        : 15 M
  Repo        : extras/7/x86_64
  
  versus
  Name        : docker-ce
  Arch        : x86_64
  Version     : 17.12.0.ce
  Release     : 1.el7.centos
  Size        : 123 M
  Repo        : installed
  From repo   : docker-ce-stable
  </code></pre>
  <p>Which would be the preferred version to run?  Newer is better or is the package that ships with CentOS extras the best?  So OS vendor or software vendor?</p>
