我的应用程序由play使用 GKE 部署的 Web 应用程序组成。该应用程序运行良好（使用Deployment和Loadbalancer服务），然后我决定使用Ingress. 我进行了以下更改，导致应用程序无法访问。当我502尝试使用ingressIP 连接应用程序时出现错误。

该应用程序是一种Deployment。

apiVersion: apps/v1
kind: Deployment
metadata:
  name: webapp
spec:
  replicas: 2
  selector:
    matchLabels:
      app: webapp

它有一个service与之相关的

apiVersion: v1
kind: Service
metadata:
  name: webapp-service
spec:
  selector:
    app: webapp
  ports:
    - protocol: TCP
      port: 9000 #this service is reachable at this port
      targetPort: 9000 #this service will forward the request to correspoding nodes of the service at this port
  #type: LoadBalancer
  type: NodePort

然后我应用以下文件来创建ingress

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: webapp-https-loadbalancer-ingress
  annotations:
    kubernetes.io/ingress.class: "gce"
spec:
  rules:
    - http:
        paths:
          - path: /*
            backend:
              serviceName: webapp-service
              servicePort: 9000

当我运行时，我可以看到有一个 IP 地址（也可以从外部访问）

kubectl describe ingress webapp-https-loadbalancer-ingress
Name:             webapp-https-loadbalancer-ingress
Namespace:        default
Address:          3x.yyy.zzz.pq
Default backend:  default-http-backend:80 (10.88.0.5:8080)
Rules:
  Host        Path  Backends
  ----        ----  --------
  *
...      Type    Reason  Age    From                     Message
      ----    ------  ----   ----                     -------
      Normal  ADD     10m    loadbalancer-controller  default/webapp-https-loadbalancer-ingress
      Normal  CREATE  9m10s  loadbalancer-controller  ip: 3x.yyy.zzz.pq

但我无法使用https://3x.yyy.zzz.pq. 我还没有将域与 IP 相关联。我尝试使用连接curl并得到错误 -502 bad gateway错误

curl -v 3x.xxx.xxx.xxx

问题是负载平衡器的 IP 不在服务器的允许主机列表中。作为临时修复，我在服务器配置中使用了通配符来允许来自所有主机的流量。我仍在研究如何将其限制为负载均衡器的内部 IP
