redhat containers uses old repositories

I personally don't know of anyone using this code to build RHEL-based images, and I'd be happy with simply removing it.

To give a bit more of context, Red Hat is using a different method to build container images that doesn't involve setting up repositories. The code linked above create confusion because it produces images that cannot be in any way be supported by Red Hat. People who want a Red Hat family distro should build using a CentOS base instead or get RHEL-base container images through official channels.

@mandre mind give more info about the image build in RHEL?

@Jeffrey: the containers are built using the koji build system. We generate Dockerfiles for each of the images using the "kolla-build --template-only" command. We also pass it with a number of overrides to disable the external repos and registration, see for example the file we're using upstream for centos [1], our downstream override is consuming the same file plus some other stuff specifically for rhel. Finally we build all the containers in isolation. So it's important for us to keep the 'rhel' base distro so if needed we can have:

{% if base_distro in ['rhel'] %}
  Do RHEL specific stuff
{% endif %}

But the rhos repos and subscription management are not used. We're removing it all with:

{% block base_rhos_repo_enablement %}
{% endblock %}
{% block base_rhel_package_installation %}
{% endblock %}
