Telco RAN distributed unit (DU) reference configuration CRs

Use the following custom resources (CRs) to configure and deploy OpenShift Container Platform clusters with the telco RAN DU profile. Some of the CRs are optional depending on your requirements. CR fields you can change are annotated in the CR with YAML comments.

You can extract the complete set of RAN DU CRs from the ztp-site-generate container image. See Preparing the GitOps ZTP site configuration repository for more information.
