Section Number and Name: 
6.1. Registering the CDS node
6.3. Enabling the required repositories on the CDS node
7.1. Registering the HAProxy node
7.3. Enabling the required repositories on the HAProxy node

Describe the issue: 
For non-SCA (simple content access) environments --type=rhui is required to subscribe to 'Red Hat Update Infrastructure and RHEL Add-Ons for Providers' using 'subscription-manager register'. It should be similar to the one used in 'Registering the RHUA node' section. 

If the node is registered with --type=rhui and attached to 'Red Hat Update Infrastructure and RHEL Add-Ons for Providers' then it should consume a different set of repositories:

=== with -rhui- suffix
rhel-8-for-x86_64-appstream-rhui-rpms
rhel-8-for-x86_64-baseos-rhui-rpms
rhceph-5-tools-for-rhel-8-x86_64-rhui-rpms
===

instead of:

===
rhel-8-for-x86_64-appstream-rpms
rhel-8-for-x86_64-baseos-rpms
rhceph-5-tools-for-rhel-8-x86_64-rpms
===

Suggestions for improvement: 
Correct the list of enabled repositories and the 'subscription-manager register' command in non-SCA sections accordingly.

Comment 1 Radek Bíba 2022-09-13 05:41:14 UTC

The RHUI consumer type is really only needed on the RHUA node. This consumer type provides access to the RHUI 4 repository, which contains the packages required on the RHUA node such as rhui-tools or various Pulpcore builds.

The CDS and HAProxy nodes don't run any software from the RHUI 4 repository. Therefore, they can be registered as the default consumer type and use the standard RHEL repositories.

Note that this was different in RHUI 3.

Comment 3 Alexey Masolov 2022-09-14 02:39:44 UTC

That would lead to using another subscription pool on the CDS and HAProxy nodes (anything that provides "Red Hat Enterprise Linux").

I reckon we need to streamline this procedure even more by using the same pool or consuming the content from the RHUA.
