第 3 章 Configuring RHEL image builder repositories

You can add repositories or override the default base repositories.

You can use the following types of repositories in RHEL image builder:

Official repository overrides
Use these if you want to download base system RPMs from elsewhere than the Red Hat Content Delivery Network (CDN) official repositories, for example, a custom mirror in your network. Using official repository overrides disables the default repositories, and your custom mirror must contain all the necessary packages.
Custom third-party repositories
Use these to include packages that are not available in the official RHEL repositories.

3.1. Adding additional repositories to RHEL image builder

You can add additional custom repositories to your image during the image-building time by using the image-builder tool and the --extra-repo flag.

Prerequisites

  • You have the URL of the custom repository.

Procedure

  • Build the image, and add the extra repository to RHEL image builder: 

    $ image-builder build <image-type> \
--add-repo=<file:///path/to/my/repo> \

    The repository content becomes available during the image building, and the dependency solver gets packages from the repository. For example, if the repository contains a libc or kernel with higher version, they will be selected over the default repositories.
