我参考了来自 Google 的以下链接以实现我的实施 https://cloud.google.com/kubernetes-engine/docs/how-to/load-balance-ingress

我正在使用 ingress-gce 启用对前端和后端的访问。

前端是基于反应的应用程序，其中服务类型为 NodePort backedn 是基于 nodeJS 的应用程序，其中服务类型为 NodePort

下面是入口配置

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: "nginx"
    kubernetes.io/ingress.global-static-ip-name: ia-dev-ip
    nginx.ingress.kubernetes.io/rewrite-target: /$1
  name: ia-prod-ingress
  namespace: default
spec:
  rules:
    - http:
        paths:
          - path: /(.*)
            backend:
              serviceName: ia-prod-landingpage-deploy-service
              servicePort: 80
          - path: /cms(/|$)(.*)
            backend:
              serviceName: ia-prod-cms-deploy-service
              servicePort: 80

以下是我在执行 kubectl 描述 ia-prod-ingress 时收到的详细信息

Name:             ia-prod-ingress
Namespace:        default
Address:          xx.xxx.xx.xx
Default backend:  default-http-backend:80 (aa.aa.aa.aa:8080)

        /cms(/|$)(.*)   ia-prod-cms-deploy-service:80 (cc.cc.cc.cc:8080)
Annotations:

  kubernetes.io/ingress.class:                  nginx
  kubernetes.io/ingress.global-static-ip-name:  ia-dev-ip
  nginx.ingress.kubernetes.io/rewrite-target:   /$1
Events:

  ----    ------  ----                 ----                      -------
  Normal  CREATE  20m                  nginx-ingress-controller  Ingress default/ia-prod-ingress
  Normal  UPDATE  3m30s (x7 over 19m)  nginx-ingress-controller  Ingress default/ia-prod-ingress

当我使用从 ingress-gce 收到的 IP 地址访问 URL 时，如下所示

http://ipaddress/ --> 前端应用程序正在按预期加载。

http://ipaddress/cms --> 我期待后端应用程序响应。然而，即使在 http://ipaddress/cms 前端应用程序正在加载..

任何想法，访问后端需要什么更正？

下面是入口配置的 yaml 文件，它可以帮助我解析所有组件的正确路径

      http:

            backend:
              serviceName: ia-prod-landingpage-deploy-service
              servicePort: 80
          - path: /cms/(.*)
            backend:
