4.2. Undercloud repositories
You run Red Hat OpenStack Platform (RHOSP) 17.1 on Red Hat Enterprise Linux (RHEL) 9.2. RHEL 8.4 Compute nodes are also supported in a Multi-RHEL environment when upgrading from RHOSP 16.2.
If you synchronize repositories with Red Hat Satellite, you can enable specific versions of the Red Hat Enterprise Linux repositories. However, the repository remains the same despite the version you choose. For example, you can enable the 9.2 version of the BaseOS repository, but the repository name is still rhel-9-for-x86_64-baseos-e4s-rpms despite the specific version you choose.
Any repositories except the ones specified here are not supported. Unless recommended, do not enable any other products or repositories except the ones listed in the following tables or else you might encounter package dependency issues. Do not enable Extra Packages for Enterprise Linux (EPEL).
