 ### Configure the operator's external REST HTTPS interface
 
 The operator can expose an external REST HTTPS interface which can be accessed from outside the Kubernetes cluster. As with the operator's internal REST interface, the external REST interface requires an SSL/TLS certificate and private key that the operator will use as the identity of the external REST interface.
