Kubernetes：不能卷曲minikube pod

Question

What happened: I have been following this guidelines: https://kubernetes.io/docs/setup/minikube/ and I have the "connection refused" issue when trying to curl the application. Here are the steps I did

~~> minikube status
minikube: Stopped
cluster: 
kubectl: 
~~> minikube start
Starting local Kubernetes v1.10.0 cluster...
Starting VM...
Getting VM IP address...
Moving files into cluster...
Setting up certs...
Connecting to cluster...
Setting up kubeconfig...
Starting cluster components...
Kubectl is now configured to use the cluster.
Loading cached images from config file.
~~> kubectl run hello-minikube --image=k8s.gcr.io/echoserver:1.10 --port=9500
deployment.apps/hello-minikube created
~~> kubectl expose deployment hello-minikube --type=NodePort
service/hello-minikube exposed
~~> kubectl get pod
NAME                              READY     STATUS    RESTARTS   AGE
hello-minikube-79577c5997-24gt8   1/1       Running   0          39s
~~> curl $(minikube service hello-minikube --url)
curl: (7) Failed to connect to 192.168.99.100 port 31779: Connection refused

What I expect to happen: When I curl the pod, it should give a proper reply (like in the quickstart: https://kubernetes.io/docs/setup/minikube/ )

Not sure where you got the port 9500 from but that's the reason it doesn't work. NGINX serves on port 8080 . This should work (it does for me, at least):

$ kubectl expose deployment hello-minikube \
          --type=NodePort \
          --port=8080 --target-port=8080


$ curl $(minikube service hello-minikube --url)
