CU requires NodePort to expose an application.

"service_type: NodePort" exists but there is not an option to set a nodeport number.

Other information and questions asked for the current platform:

If you want a NodePort instead of clusterIP you can add following configuration

spec:
  service_type: nodeport
  controller:
    service_type: nodeport
    nodeport_port: <your controller port number>
  eda:
    service_type: nodeport
    nodeport_port: <your eda port number>
  hub:
    ingress_type: nodeport
    nodeport_port: <your hub port number>

Unfortunately, CRD of gateway doesn't seem to allow nodeport_port spec, that means operator will randomly choose available port instead to allow you pick up one.

With such a configuration, all services to access different component will be a nodeport. And the route automatically created will point to those services. 

If, for any reason, you don't want a route to be created you can add the spec for controller, gateway and eda.

ingress_type: None
