+=== Accessing app from outside the cluster
+
+If your cluster doesn’t support external load balancers, like the Minikube, then you must use the NodePort approach.
+You can use deployment properties for configuring the access. Use `deployer.http.kubernetes.createLoadBalancer=true`
+for the app to specify that you want to have a LoadBalancer with an external IP address created for your app’s service.
+For the NodePort configuration use `deployer.http.kubernetes.createNodePort=<port>`
+where <port> should be a number between 30000 and 32767.
+
+=== UI
+
+.go to UI - user / password
+----
+open $(minikube service --url scdf-server)

+=== cleanup
