【问题描述】：

我正在使用带有 AWS tls 证书的 kubernetes 集群使用 ingress-nginx。

frontend 和 backend 服务都在集群内运行。

我能够查看前端，但是当它与后端交互时会抛出错误：

ERR_TOO_MANY_REDIRECTS

入口 nginx

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: ingress-service
  annotations:

            backend:
              serviceName: aws-srv
              servicePort: 3000

入口 nginx 服务

    - name: https
      port: 443
      protocol: TCP
      targetPort: http
  selector:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/component: controller

我被困在这里，无法将其投入生产，提前致谢！

【问题讨论】：

您是否也在这张图片中使用 AWS API Gateway，就像入口之前的任何地方一样？

标签： node.js docker nginx kubernetes kubernetes-ingress

【解决方案1】：

您在后端定义了哪个 URL？如果是www.example.com，则删除- example.com 这一行。

我认为您应该在此删除 aline：

spec:
  tls:
  - hosts:
      - example.com
      - www.example.com

删除：- example.com 然后再次检查。

或者你保留两个主机：但重新配置：nginx.ingress.kubernetes.io/from-to-www-redirect: "false"
