Ingress Nginx Controller未能找到部署在谷歌云平台上的第二个服务

Question

我在GCP上部署了以下2个服务(用Java构建(：

• mply6(服务1，监听GCP外部的8080端口(，对应URL：http://example.com/path1

• gami6(服务2，监听GCP外部的8081端口(，对应URL：http://example.com/path2

部署和公开服务1:的yaml

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:

spec:

app: mply6
spec:
containers:
- name: mply6
image: gcr.io/mply6-271000/mply6:latest
ports:
- containerPort: 8080

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:

app: gami6
spec:
containers:
- name: gami6
image: gcr.io/mply6-271000/gami6:latest
ports:
- containerPort: 8081

并且，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描述入口基本入口"的结果：

基本上，我希望当我给出URL时http://example.com/path2'，Ingress Nginx控制器会找到第二个服务"gami6"，但为什么会出现上面的错误消息：找不到服务"default/gami6"？(http://example.com/path1可以在没有问题的情况下找到(

Answer 1

首先，我注意到第二个服务yaml:的拼写错误

规格：选择器：应用程序：gmai6<--这应该是gami6吗？

要在多个后端使用Google的Ingress，您可能需要使用"NodePort"而不是"LoadBalancer"来公开服务。您可以在本文档中找到相关信息：https://cloud.google.com/kubernetes-engine/docs/concepts/ingress#multiple_backend_services

如果你想使用nginxingress控制器，你应该遵循以下指南：https://cloud.google.com/community/tutorials/nginx-ingress-gke

我无法对您上面的部署添加任何备注。然而，此部署与http平衡器文档非常相似

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。使用负载均衡器根据路径路由请求。
