title: How to reduce the size of RHEL/Centos/Fedora Docker image
body: <p>The base image from Red Hat is quite small, on the order of 196M for RHEL 7.4. However it tends to be missing a lot of the bits and pieces that are required by the products I want to build new images for.</p>
  
  <p>The moment I do a "yum install Xxx" on top of it the image size blows out to by +500M-800M.</p>
  
  <p>Is there a way to reduce the size of the image?</p>
