+  # We usually recommend not to specify default resources and to leave this as a conscious

+  # resources, such as Minikube. If you do want to specify resources, uncomment the following

+  # Example:
+  # Configure resource requests and limits
+  # ref: http://kubernetes.io/docs/user-guide/compute-resources/
+  # Minimum memory for development is 2 CPU cores and 4GB memory
