Chapter 3. Repositories
Red Hat Enterprise Linux 8 is distributed through two main repositories:
Both repositories are required for a basic RHEL installation, and are available with all RHEL subscriptions.
Content in the BaseOS repository is intended to provide the core set of the underlying OS functionality that provides the foundation for all installations. This content is available in the RPM format and is subject to support terms similar to those in previous releases of RHEL. For a list of packages distributed through BaseOS, see the Package manifest.
Content in the Application Stream repository includes additional user space applications, runtime languages, and databases in support of the varied workloads and use cases. Content in AppStream is available in one of two formats - the familiar RPM format and an extension to the RPM format called modules. For a list of packages available in AppStream, see the Package manifest.
In addition, the CodeReady Linux Builder repository is available with all RHEL subscriptions. It provides additional packages for use by developers. Packages included in the CodeReady Linux Builder repository are unsupported.
For more information about RHEL 8 repositories, see the Package manifest.
