Ingress-Nginx-Controller未能找到部署在Google Cloud Platform上的第二项服务

Question

我在GCP上部署了以下2种服务（使用Java内置）：

• mply6（服务1，在GCP外部的端口8080上侦听），对应于URL：http://example.com/path1

• gami6（服务2，在GCP外部的端口8081上侦听），对应于URL：http://example.com/path2

部署和公开服务的Yaml 1：

kind: Service
apiVersion: v1
metadata:
  name: mply6
spec:
  selector: 
      app: mply6
  ports:
     - protocol: "TCP"
       port:  80
       targetPort:  8080
  type: LoadBalancer
  loadBalancerIP: "35.223.241.9"

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: mply6
spec:
  replicas: 1
  selector: 
    matchLabels:
      app: mply6
  template:
    metadata:
      labels:
        app: mply6
    spec:
      containers:
      - name: mply6
        image: gcr.io/mply6-271000/mply6:latest
        ports:
        - containerPort: 8080

用于部署和公开服务的Yaml 2：

kind: Service
apiVersion: v1
metadata:
  name: gami6
spec:
  selector: 
      app: gmai6
  ports:
     - protocol: "TCP"
       port:  81
       targetPort:  8081
  type: LoadBalancer
  loadBalancerIP: "35.223.241.9"

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: gami6
spec:
  replicas: 1
  selector: 
    matchLabels:
      app: gami6
  template:
    metadata:
      labels:
        app: gami6
    spec:
      containers:
      - name: gami6
        image: gcr.io/mply6-271000/gami6:latest
        ports:
        - containerPort: 8081

而且，用于创建Ingress资源的Yaml：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: basic-ingress
  annotations:
    kubernetes.io/ingress.global-static-ip-name: "35.223.241.9"
spec:
  rules:
  - http:
      paths:
      - path: /path1
        backend:
          serviceName: mply6
          servicePort: 80
      - path: /path2
        backend:
          serviceName: gami6
          servicePort: 81

此外，'kubectl的结果描述了入口基本入口'：

Name:             basic-ingress
Namespace:        default
Address:          35.244.199.199

Rules:

        /leaders                  gami6:81 (10.60.0.32:8081)
        /stats                    gami6:81 (10.60.0.32:8081)

  Normal   UPDATE     7s (x13 over 35m)     nginx-ingress-controller  Ingress default/basic-ingress

基本上，我期望当我给URL'http://example.com/path2'时，Ingress-Nginx-Controller会找到第二个服务'gami6'，但是为什么出现上述错误消息：找不到服务“ default / gami6 “？ （在没有问题的情况下可以找到http://example.com/path1）

Answer 1

我无法在上面的部署中添加任何备注。但是，此部署与http-balancer documentation

非常相似

我尝试了文档中提到的部署，并且能够实现您想要做的事情。使负载均衡器根据路径路由请求。
