Chapter 9. Managing custom software repositories

To provide your Red Hat Enterprise Linux (RHEL) 10 systems with access to organization-specific or third-party software, add and configure custom repositories by using the DNF tool. By managing these custom sources, you can install and update specialized packages required for your environment.

You can configure a repository in the /etc/dnf/dnf.conf file or in a .repo file in the /etc/yum.repos.d/ directory.

The /etc/dnf/dnf.conf file contains the [main] section and can contain one or more repository sections with a unique repository ID in brackets ([]), for example, ([<repository-ID>]). You can use these sections to define individual DNF repositories by setting repository-specific options. Note that repository IDs must be unique. The values you define in individual repository sections of the /etc/dnf/dnf.conf file override values set in the [main] section for this repository.

For a complete list of available repository ID options, see the [<repository_ID>] OPTIONS section of the dnf.conf(5) man page.

Consider adding your custom repositories in separate .repo files instead of the /etc/dnf/dnf.conf DNF configuration file to avoid possible issues if other programs modify the DNF configuration file.

You can add the DNF repository to your system by using the dnf config-manager --add-repo command. Repositories that you add with this command are enabled by default. However, you can also use the dnf config-manager command to disable the repository.
