Chapter 2. Applying patches to your registered systems
Chapter 2. Applying patches to your registered systems Important Red Hat Insights is deprecating patch templates and introducing content templates as the way to manage the content in your Red Hat Enterprise Linux (RHEL) environment. Patch templates filter the errata that can be applied to registered systems in the Hybrid Cloud Console. Content templates provide filtering and control on the systems themselves. In addition, you can use the same set of content to build custom images in Insights. Content templates are currently available in Preview mode. To start using content templates, click the Preview toggle at the top of your Insights window. The Red Hat Insights patch application supports scheduled patching cycles. You can create a patch template to update a group of systems in a test environment, and use the same patch template to update systems in a production environment on a different day. 2.1. How patch templates work The Red Hat Insights patch application supports scheduled patching cycles. You can create a patch template to update a group of systems in a test environment, and use the same patch template to update systems in a production environment on a different day. Use patch templates to enter criteria that limit the scope of advisories that apply to your systems. For example, you can create a template to show only applicable advisories that were published up to the date of your current patching cycle. After you create the template, use the wizard to add systems and select the date of the patching cycle. When you have finished adding systems to the patch template, you can remediate all the installable advisories for the selected group of systems. If a system already has a patch template applied, applying a different patch template overrides the existing template. A system can only have one patch template at a time. For more information about remediations, see the Red Hat Insights Remediations Guide . Note After you apply a patch template to the systems you assign, you will not see more recently published advisories that apply to those systems. Use Red Hat Hybrid Cloud Console notifications to ensure that you remain aware of newly published advisories that might affect your infrastructure. For more information about notifications in the Red Hat Hybrid Cloud Console, see Configuring notifications on the Red Hat Hybrid Cloud Console . Patch templates do not affect yum/dnf operations on the host, but they allow you to refine your patch status reporting in Red Hat Insights. You can use the templates to create remediation playbooks for simple patch cycles. 2.2. Creating a patch template You can create a patch template to limit the scope of advisories that apply to your systems. For example, you can ignore advisories that were published after the date of your current patching cycle. Prerequisites You are logged into the Red Hat Hybrid Cloud Console as an Organization Administrator. Procedure Use the left menu to navigate to Content > Templates . Click Create a template .
