title: Use Satellite repositories during docker build on RHEL8
body: <p>I need to be able to use my company's satellite repository while building docker image on top of Red Hat 8 UBI image.
  I was able to achieve that by copying from host machine those files:</p>
  <pre><code>/etc/yum.repos.d/
  /etc/rhsm
  /etc/pki/
  </code></pre>
  <p>to image during build, however it doesn't seem to be elegant solution.</p>
  <p>Is there any way to tell docker to use Host machine entitlements/yum repos during docker build?</p>
  <p>EDIT: Did some further research, looks like this functionality is not available on Docker-CE. To workaround this, I had to use Podman instead of Docker, which offers this out of the box.</p>
