I don’t know, in RHEL when we talk about Red Hat Enterprise Linux 7 Server (RPMs) it’s equivalent to CentOS “os” directory, so it would be: http://mirror.centos.org/centos/7.6.1810/os; this generates another problem: a product for each repository: extras, updates, etc. Correct me if I’m wrong please.
So at this moment I’m with the same issue, the Product thing is really confusing. I’ve look through the list history and the confusion is present in a lot of posts. There are ppl that just put a product named CentOS and put everything from 5 to 7, other considers a product a major release, and etc.
Another question is why pulp can’t just create a folder structure for CentOS just like the official mirrors, it would be simple, but we don’t have the control to create our own path structure within the web interface.
