docker - Kubernetes:无法 curl minikube pod

Question

发生了什么:
我一直在遵循以下准则:https://kubernetes.io/docs/setup/minikube/并且在尝试 curl 应用程序时遇到“连接被拒绝”问题。这是我做的步骤

~~> 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

我期望发生的事情:
当我 curl pod 时，它应该给出正确的答复(如快速入门: https://kubernetes.io/docs/setup/minikube/ )

Answer 1

不确定你从哪里得到的端口 9500 from 但这就是它不起作用的原因。 NGINX 服务于端口 8080 .这应该有效(至少对我有用):

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


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

Hostname: hello-minikube-79577c5997-tf49z
