+  echo http://$NODE_IP:$NODE_PORT
+{{- else if contains "LoadBalancer" .Values.service.type }}
+  NOTA: Potrebbe volerci qualche minuto per ottenere l'IP del LoadBalancer.
+  Controlla lo stato con:

+
+  export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ include "rrt-sales-wizard.fullname" . }} --template "{{"{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"}}")

+
+  Poi apri: http://localhost:8080
