无法在win10机器上使用码头桌面访问Kubernetes服务

Question

这是我的pod.yaml文件

apiVersion: v1
kind: Pod
metadata:
  name: voting-app-pod
  labels:
    name: voting-app-pod
    app: demo-voting-app
spec:
  containers:
    - name: voting-app
      image: kodekloud/examplevotingapp_vote:v1
      ports:
        - containerPort: 80

这是我的service.yaml文件

apiVersion: v1
kind: Service
metadata:
  name: voting-service
  labels: 
    name: voting-service
    app: demo-voting-app
spec:
  type: NodePort
  ports:
    - port: 80
      targetPort: 80
      nodePort: 30004
  selector:
    name: voting-app-pod
    app: demo-voting-app

执行后

kubectl get pods,svc 

我得到了

NAME                 READY   STATUS    RESTARTS   AGE

pod/voting-app-pod   1/1     Running   0          37m

NAME                     TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE

service/kubernetes       ClusterIP   10.96.0.1        <none>        443/TCP        11d

service/voting-service   NodePort    10.107.145.225   <none>        80:30004/TCP   6m45s

我试图通过http://localhost:30004访问服务，但也尝试了http://127.0.0.1:30004，但没有成功。

请在部署中有选择器和模板标签声明，如下所示。有关属性的详细信息，请参阅kubernetes文件

spec:
  selector:
    matchLabels:
      app: demo-voting-app
  template:
    metadata:
      labels:
        app: demo-voting-app

并按以下方式服务

selector:
  app: demo-voting-app
