我正在尝试使用 Kubernetes、定义的服务和带有静态 IP 和 ssl 证书的入口将两个 nodejs 应用程序部署为两个单独的容器

我想使用 GCP 的 Kubernetes Engine 部署这些微服务。我添加的第二个微服务比另一个晚。pod 中只有一个容器，一切正常。我定义了三个 yaml 文件：deployment.yaml、service.yaml、ingress.yaml。

部署.yaml

apiVersion: apps/v1beta2
kind: Deployment
metadata:
  name: qa-chatbot-backend-deployment
spec:
  selector:
    matchLabels:
      app: service-backend1
  replicas: 1
  template:
    metadata:
      labels:
        app: service-backend1
    spec:
      containers:
        - name: serice-backend1
          image: gcr.io/project-id/serice-backend1:v1.0.1
          imagePullPolicy: Always
          command: ["npm", "start"]
          livenessProbe:
            httpGet:
              path: /
              port: 8081
              scheme: HTTP
            initialDelaySeconds: 30
            timeoutSeconds: 25
            periodSeconds: 30
            successThreshold: 1
            failureThreshold: 2
          readinessProbe:
            httpGet:
              path: /
              port: 8081
              scheme: HTTP
            initialDelaySeconds: 30
            timeoutSeconds: 25
            periodSeconds: 30
            successThreshold: 1
            failureThreshold: 2
          ports:
            - name: service1-port
              containerPort: 8081
        - name: service-backend2
          image: gcr.io/project-id/serice-backend2:v1.0.1
          imagePullPolicy: Always
          command: ["npm", "start"]
          livenessProbe:
            httpGet:
              path: /api/test
              port: 8082
              scheme: HTTP
            initialDelaySeconds: 30
            timeoutSeconds: 25
            periodSeconds: 30
            successThreshold: 1
            failureThreshold: 2
          readinessProbe:
            httpGet:
              path: /api/test
              port: 8082
              scheme: HTTP
            initialDelaySeconds: 30
            timeoutSeconds: 25
            periodSeconds: 30
            successThreshold: 1
            failureThreshold: 2
          ports:
            - name: service2-port
              containerPort: 8082

服务.yaml

apiVersion: v1
kind: Service
metadata:
  name: service-kube
spec:
  type: LoadBalancer
  ports:
    - targetPort: service1-port
      port: 80
      protocol: TCP
  selector:
    app: service-backend1

入口.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  labels:
    app: service-backend1
  name: ingress-kube
  annotations:
    kubernetes.io/ingress.global-static-ip-name: app-static-ip
spec:
  tls:
  - hosts:
    - custom-host.com
    secretName: custom-host-secret-name
  rules:
  - host: custom-host.com
    http:
      paths:
      - backend:
          serviceName: service-kube
          servicePort: 80

使用此配置，只能访问一个服务，第一个

我尝试将多个端口添加到 service.yaml

apiVersion: v1
kind: Service
metadata:
  name: service-kube
spec:
  type: LoadBalancer
  ports:
    - targetPort: service1-port
      port: 80
      protocol: TCP
    - targetPort: service2-port
      port: 80
      protocol: TCP
  selector:
    app: service-backend1

但我收到一个错误。

The Service "service-kube" is invalid: spec.ports[1]: Duplicate value: core.ServicePort{Name:"", Protocol:"TCP", Port:80, TargetPort:intstr.IntOrString{Type:0, IntVal:0, StrVal:""}, NodePort:0}

我的目标是在域 custom-host.com 上公开两个后端；一个可在特定路径 (api/*) 上到达，另一个可到达所有可能的端点。

谢谢您的帮助

You can't have a single service port send traffic to two different target ports. There must be two different ports on your service (or use two separate services). Then you should have two paths in your ingress that route to the appropriate service port.

You need to do something like this...

apiVersion: v1
kind: Service
metadata:
  name: service-kube
spec:
  type: LoadBalancer
  ports:
    - targetPort: service1-port
      port: 81
      protocol: TCP
    - targetPort: service2-port
      port: 82
      protocol: TCP
  selector:
    app: service-backend1

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  labels:
    app: service-backend1
  name: ingress-kube
  annotations:
    kubernetes.io/ingress.global-static-ip-name: app-static-ip
spec:
  tls:
  - hosts:
    - custom-host.com
    secretName: custom-host-secret-name
  rules:
  - host: custom-host.com
    http:
      paths:
      - backend:
          serviceName: service-kube
          servicePort: 81
        path: /api
      - backend:
          serviceName: service-kube
          servicePort: 82
        path: /
