无法配置 NGINX 入口控制器

use*_*970 0 kubernetes amazon-eks nginx-ingress

我有一个 eks 集群,我的部署、服务和 loadBalancer 一切正常。每个服务都创建了自己的 LoadBalancer,所有服务都已启动并正在运行。我有一个前端服务和 2 个后端服务,这里是我的部署和入口文件

我有一个类似的部署和服务 yaml 文件,用于部署和创建 nginx Web 服务器。我还运行了以下命令所有部署都需要以下强制命令。

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/mandatory.yaml

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/cloud-generic.yaml

如该网址中所述https://kubernetes.github.io/ingress-nginx/deploy/#aws

然后我运行这两个命令 kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/aws/service-l4.yaml kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/aws/patch-configmap-l4.yaml

我运行kubectl get all,我看到我的 pod、replicatsets 和部署运行良好,

kubectl get ingress shows 
hosts                 ADDRESS
apache.example.com   216990309c-1626238635.us-east-2.elb.amazonaws.com
nginx.example.com    216990309c-1626238635.us-east-2.elb.amazonaws.com

我期待当我点击时apache.example.com- 它应该显示“它有效”并且 Nginx.example.com 应该显示“欢迎 Nginx”

我这样做对吗

所以只是一个想法(我可能错过了阅读你的问题)但入口控制器不会直接路由到你的部署,它需要一个服务来路由,所以在你的情况下你必须创建一个这样的服务:

apiVersion: v1
kind: Service
metadata:
  name: apache-kubernetes
spec:
  selector:
    app: apache-kubernetes
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80

然后,这将使用端点配置 nginx 入口以路由到您在入口中指定的位置:

...
paths:
      - path: /
        backend:
          serviceName: apache-kubernetes
          servicePort: 80

这将指向服务而不是部署

流程(逻辑上因为 nginx 入口为更少的跳数做了一些魔法):

浏览器 ==>ALB==>ekscluster==>入口控制器==>服务==>pod
