How to enable and make use of content within CodeReady Linux Builder

Updated 31 Jan 2023

Overview

Alongside the primary two repositories available within Red Hat Enterprise Linux 8, unsupported additional content is provided within the new CodeReady Linux Builder (CRB) repository.

For overview information regarding this content, please see the following:

Introducing the CodeReady Linux Builder Repository - Red Hat Customer Portal:

As the content available with CRB is unsupported, it is disabled by default. Additional action is necessary to install RPMs and Modules shipped within that repository.

Enabling the Repository

To enable the repository, the following subscription-manager command can be used:

# subscription-manager repos --enable <repo-id>      ##syntax##
# subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms

This will allow most content to be available for installation. Specifically, any content that is available as a non-modularized RPM will be able to be installed.

CodeReady Linux Builder Modules

The CRB repository also includes a number of modules. The following is a list of available modules at the time of this article being written:

# yum module list --disablerepo=* --enablerepo=codeready-builder-for-rhel-8-x86_64-rpms

Red Hat CodeReady Linux Builder for RHEL 8 x86_64 (RPMs)
Name                      Stream        Profiles        Summary                                          
javapackages-tools        201801        common          Tools and macros for Java packaging support      
virt-devel                rhel                          Virtualization module                            
 
Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

In the output above, the javapackages-tools module includes a common profile, but it is not defined as the default. The virt-devel module does not include a profile. With either of these states, no profile included or a profile included but not the default, it is necessary to enable the module stream in order to install included content.
# yum module info javapackages-tools | grep xz-java

No match for argument: xz-java
Error: Unable to find a match

The output above shows that the modularized xz-java package cannot be installed by default. In order to do so, the module must first be enabled.
