+If you meet connection problems with minikube, try getting the service name and exposing the service like this:
+
+```bash
+# kubectl get services
+minikube service coordinator-service-<release-name> --url
+```
+
+For more usage, you could refer to [minikube's accessing tutorial](https://minikube.sigs.k8s.io/docs/handbook/accessing/).
