title: AWS EC2 instance based on RHEL7.2 ami can not install Docker
body: <p>I created one EC2 instance that's based on <strong><em>AMI</em></strong>: <strong>RHEL-7.2_HVM-20161025-x86_64-1-Hourly2-GP2 - ami-2265c543</strong> , but when I wanna install docker via <code>yum install docker -y</code> it shows me error: <code>No package docker available. Error: Nothing to do</code> . So anyone know how to install docker on this ami OS?
  thanks in advance.</p>
