Question

我正在GCE上使用本教程ingress。本教程在其中使用docker镜像的情况下工作正常，但对于我的docker镜像，我总是得到后端服务的状态异常。我添加了活跃性和就绪性TCP探针，因为我的应用程序不响应200。部署yaml如下图所示

app.get('/searchUser/:value', function (req, res) {
    let value = req.params.value;

    console.log(value + ' <<< value in the server');

    user.find({ user: value}, function(err, doc) {
        if(err) {
          console.log(err);  
        }else {
            // res.json(res);
            console.log(doc);
        }
    });
})

服务Yaml如下所示

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    run: neg-demo-app # Label for the Deployment
  name: neg-demo-app # Name of Deployment
spec: # Deployment's specification
  selector:
    matchLabels:
      run: neg-demo-app
  template: # Pod template
    metadata:
      labels:
        run: neg-demo-app # Labels Pods from this Deployment
    spec: # Pod specification; each Pod created by this Deployment has this specification
      containers:
      - image: mohib13/graphene_with_coref:first # Application to run in Deployment's Pods
        name: hostname # Container name
        readinessProbe:
          tcpSocket:
            port: 8080
          initialDelaySeconds: 5
          periodSeconds: 10
        livenessProbe:
          tcpSocket:
            port: 8080
          initialDelaySeconds: 15
          periodSeconds: 20
        ports:
        - containerPort: 8080
      terminationGracePeriodSeconds: 60 # Number of seconds to wait for connections to terminate before shutting down Pods

入口低于下方

apiVersion: v1
kind: Service
metadata:
  name: neg-demo-svc # Name of Service
  annotations:
    cloud.google.com/neg: '{"ingress": true}' # Creates an NEG after an Ingress is created
spec: # Service's specification
  type: NodePort
  selector:
    run: neg-demo-app # Selects Pods labelled run: neg-demo-app
  ports:
  - port: 8080 # Service's port
    targetPort: 8080

更新：描述如下所示的广告连播

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: neg-demo-ing
spec:
  backend:
    serviceName: neg-demo-svc # Name of the Service targeted by the Ingress
    servicePort: 8080 # Should match the port used by the Service
