+
+This deployment will be incomplete until you configure Ghost with a resolvable

+

+
+  export APP_HOST=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")

+
+  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
+        Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "common.names.fullname" . }}'
+
+  export APP_HOST=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "common.names.fullname" . }} --template "{{ "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}" }}")
