Question

我有一个eks集群，我的部署，服务和loadBalancer都可以正常工作。每个服务都创建自己的LoadBalancer，所有服务都已启动并正在运行。我有一个前端服务和2个后端服务这是我的部署和入口文件

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: apache-kubernetes
spec:
  replicas: 2
  selector:
    matchLabels:
      app: apache-kubernetes
  template:
    metadata:
      labels:
        app: apache-kubernetes
    spec:
      containers:
      - name: apache-kubernetes
        image: httpd
        ports:
        - containerPort: 80
        env:
        - name: MESSAGE
          value: Hello Kubernetes!
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: hello-apache-ingress
  annotations:
    kubernetes.io/ingress.class: "nginx"

spec:
  rules:
  - host: apache.example.com
  - http:
      paths:
      - path: /
        backend:
          serviceName: apache-kubernetes
          servicePort: 80

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性命令。

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

和

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

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

中所述

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，我看到自己的Pod，副本集和部署运行正常

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

我期望当我点击apache.example.com时，它应该显示“有效” 和Nginx.example.com应该显示“ welcome Nginx”

我做对了

浏览器==> ALB ==> ingresscontroller ==> ekscluster

当我点击网址时，我得到503，但吊舱正在运行

kubectl -n ingress-nginx记录nginx-ingress-controller-db5f9d7b5-cwwh2

给我

所以只是一个想法（我可能会错过阅读您的问题），但是入口控制器不会直接路由到您的部署，它需要一个服务进行路由，因此在您的情况下，您必须创建一个服务像这样：

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

这将为nginx入口配置要路由到的端点，在入口中您指定以下位置：

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

这将指向服务而不是部署

流（从逻辑上讲，nginx入口为减少跳数做了一些魔术）：

浏览器==> ALB ==> ekscluster ==> ingresscontroller ==> service ==> pod

无法配置NGINX入口控制器
