Certificate management and DNS
You must be aware of the reasons why an external DNS is required for CDP Private Cloud Data Services installation along with the required setup in the cluster.
An external DNS must be available to route inbound traffic to the cluster through the load balancer. The external DNS should contain forward and reverse zones for both the OpenShift and the CDP Private Base cluster nodes.
Ensure that the canonical load balancers required for OpenShift is routable from within the OpenShift cluster and from any other location that you want to access resources in the Management Console; this is a standard requirement for on-premises load balancers communicating Kubernetes clusters.
There must also be a set of certificates set up for use by the OpenShift Route ingress controller as defined in the OpenShift bare metal install guide that the Cloudera services use.
