Chapter 9. Managing custom repositories Custom repositories extend the images you build in the edge management application to packages beyond those that Red Hat provides. You can customize the images with custom repositories and custom packages that fit your specific business case. For example, you can add packages from the Extra Packages for Enterprise Linux (EPEL), or any compatible package list. You can update your existing images by adding or removing packages from these custom repositories. You can also remove repositories, and also add repositories from the popular repositories. 9.1. Adding a custom repository To add packages from the third-party repository to your customized images, you must first define your repository with third-party information. Prerequisites You have a RHEL subscription. You have administrator access to the Red Hat Hybrid Cloud Console web user interface or repository administrator role. You have the URL for your custom repository. Procedure Access Hybrid Cloud Console . Click Red Hat Insights > RHEL > Content > Repositories . The Custom repositories dashboard appears. Click Add repositories . The Add custom repositories wizard opens. Enter the following information: NAME - mandatory. URL - mandatory. In the Restrict architecture drop-down menu, select an architecture. You can allow all the architectures or restrict one to your system architecture to prevent incorrect repositories availability. In the Restrict OS version drop-down menu select an operating system (OS). You can allow all the RHEL versions or select one for your system version to prevent incorrect repositories being available. GPG key - upload the .txt file with a GPG key or paste the URL or value of an existing GPG key. The GPG key verifies the signed packages of a repository. If you do not provide the GPG key for a repository, your system cannot perform the verification. If you want to add another repository, click the Add another repository button and repeat step 3. Click Save . The Red Hat Hybrid Cloud Console validates the project status. If your repository is marked as Invalid , check the repository URL that you added. Verification Open the list of custom repositories and verify that the repository you added is listed.
