Question

我已经创建了部署和服务，并使用kubernetes部署它们，当我尝试通过curl访问它们时，我总是遇到连接超时错误。

这是我的yml文件：

Deployment.yml

        apiVersion: extensions/v1beta1
    kind: Deployment
    metadata:
      labels:
        app: locations-service
      name: locations-service
      namespace: default
    spec:
      replicas: 2
      selector:
        matchLabels:
          app: locations-service
      template:
        metadata:
          labels:
            app: locations-service
        spec:
          containers:
            - image: dropwizard:latest
              imagePullPolicy: Never # just for testing!
              name: locations-service
              ports:
                - containerPort: 8080
                  protocol: TCP
                  name: app-port
                - containerPort: 8081
                  protocol: TCP
                  name: admin-port
              resources: {}
          dnsPolicy: ClusterFirst
          restartPolicy: Always
          schedulerName: default-scheduler

Service.yml

        apiVersion: v1
    kind: Service
    metadata:
      labels:
        app: locations-service
      name: locations-service
      namespace: default
    spec:
      type: NodePort
      externalTrafficPolicy: Cluster
      ports:
      - name: "8080"
        port: 8080
        targetPort: 8080
        protocol: TCP
      - name: "8081"
        port: 8081
        targetPort: 8081
        protocol: TCP
      selector:
        app: locations-service

此外，我尝试添加入口路由，并试图点击它们但仍然会出现同样的问题。

请注意，应用程序已成功部署，我可以从k8s仪表板检查日志

另一个例子，我有以下svc

kubectl describe service webapp1-svc
Name:                     webapp1-svc
Namespace:                default
Labels:                   app=webapp1
Annotations:              <none>
Selector:                 app=webapp1
Type:                     NodePort
IP:                       10.0.0.219
Port:                     <unset>  80/TCP
TargetPort:               80/TCP
NodePort:                 <unset>  30080/TCP
Endpoints:                172.17.0.4:80
Session Affinity:         None
External Traffic Policy:  Cluster
Events:                   <none>

并尝试使用

访问它

curl -v 10.0.0.219:30080
* Rebuilt URL to: 10.0.0.219:30080/
*   Trying 10.0.0.219...
* connect to 10.0.0.219 port 30080 failed: Connection timed out
* Failed to connect to 10.0.0.219 port 30080: Connection timed out
* Closing connection 0
curl: (7) Failed to connect to 10.0.0.219 port 30080: Connection timed out
