title: How to prevent docker from searching docker hub
body: <p>I'm standing up a few docker hosts to run in a production environment. We want all of our images to have to go through our container pipeline and we do not want to be able to pull images from Docker Hub (security concerns).</p>
  
  <p>How can I stop docker being able to pull images from dockerhub? Ideally I would like to do this via configuring the docker daemon.</p>
