You can use PolicyGenTemplate CRs to deploy custom functionality in your managed clusters.
Using RHACM and PolicyGenTemplate CRs is the recommended approach for managing policies and deploying them to managed clusters. This replaces the use of PolicyGenTemplate CRs for this purpose. For more information about PolicyGenTemplate resources, see the RHACM Policy Generator documentation.
Using PolicyGenTemplate CRs to manage and deploy policies to managed clusters will be deprecated in an upcoming OpenShift Container Platform release. Equivalent and improved functionality is available using Red Hat Advanced Cluster Management (RHACM) and PolicyGenerator CRs.
For more information about PolicyGenerator resources, see the RHACM Integrating Policy Generator documentation.
11.2.1. Deploying additional changes to clusters
If you require cluster configuration changes outside of the base GitOps Zero Touch Provisioning (ZTP) pipeline configuration, there are three options:
- Apply the additional configuration after the GitOps ZTP pipeline is complete
- When the GitOps ZTP pipeline deployment is complete, the deployed cluster is ready for application workloads. At this point, you can install additional Operators and apply configurations specific to your requirements. Ensure that additional configurations do not negatively affect the performance of the platform or allocated CPU budget.
- Add content to the GitOps ZTP library
- The base source custom resources (CRs) that you deploy with the GitOps ZTP pipeline can be augmented with custom content as required.
- Create extra manifests for the cluster installation
- Extra manifests are applied during installation and make the installation process more efficient.
Providing additional source CRs or modifying existing source CRs can significantly impact the performance or CPU profile of OpenShift Container Platform.
