+You have enabled the Kubernetes dashboard. For security purposes, it is not
+exposed to the internet as is, however, by adjusting the settings, you could
+expose it.
+
+To connect to the dashboard, start port-forwarding with the following command:
+
+    kubectl -n harmony port-forward svc/harmony-nginx-controller 8443:443
+
+Now you can connect to https://localhost:8443. The certificate is self-signed by
