Chapter 1. Distribution of content in RHEL 10
In Red Hat Enterprise Linux (RHEL) 10, software is distributed through different repositories. You can access applications and core components through these repositories to ensure your system remains stable and up-to-date.
1.1. Repositories
Red Hat Enterprise Linux (RHEL) 10 repositories provide the specific software, operating system functionality, and various system components you need for a stable and supported environment.
Red Hat Enterprise Linux distributes content through different repositories, for example, BaseOS, AppStream, CodeReady Linux Builder, and Supplementary. In addition, specific content is available in the Red Hat Enterprise Linux Add-on repositories, such as High Availability.
The main repositories that RHEL uses to distribute its content include the following repositories:
- BaseOS
- Content in the BaseOS repository consists of the core set of the underlying operating system 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 earlier releases of RHEL.
- AppStream
- Content in the AppStream repository includes additional user-space applications, runtime languages, and databases in support of the varied workloads and use cases.
Both the BaseOS and AppStream content sets are required by RHEL and are available in all RHEL subscriptions.
- CodeReady Linux Builder
- The CodeReady Linux Builder repository is available with all RHEL subscriptions. It provides additional packages for use by developers. Red Hat does not support packages included in the CodeReady Linux Builder repository.
1.2. Application Streams
Red Hat provides multiple versions of user-space components as Application Streams, and they are updated more frequently than the core operating system packages. This provides more flexibility to customize RHEL without impacting the underlying stability of the platform or specific deployments.
Application Streams are available in the following formats:
- RPM format
- Software Collections
RHEL 10 provides initial Application Stream versions as RPMs, which you can install by using the dnf install command.
Each Application Stream has its own life cycle, which can be the same as or shorter than the life cycle of Red Hat Enterprise Linux 10.
Determine which version of an Application Stream you want to install, and review the Red Hat Enterprise Linux Application Stream life cycle first.
