YUM Repo Setup | RHEL 8 | AppStream & BaseOS YUM Repository | Tech Arkit

Yum is the Red Hat package manager that is able to query information about available packages, fetch packages from configured repositories, install and uninstall them, and update an entire system to the latest available version. Yum performs automatic dependency resolution on packages you are updating, installing, or removing, and thus is able to automatically determine, fetch, and install all available dependent packages. In this article YUM ( YellowDog Updater Module ) Local installation and configuration step by step guide.

One question, can we just baseurl from the mounted folder? just to avoid copying the AppStream and BaseOS.

Yes, you can do that, thing is RPMs and .XML files should be available for the read then you can point any path to create repo.

​@@catchmeifyoucan_2024 You can take advantage of the "priority plugin" where you can set priorities to the repos and the lower the priority value the higher the priority of that repo. You can set the "offline" repo as higher priority, online repo as lower priority and if the offline repo can't satisfy the yum need it fail and it will try the next priority repo. I hope this helps.
