Nginx 入口控制器在带有路由前缀的 Node.js 应用程序中出错

问题描述

我在 Google Kubernetes Engine 上托管的 Kubernetes 集群中使用 Ingress Nginx 控制器。该应用程序是一个 Node.js 应用程序。

当我将我的应用与 Rollbar（记录器服务）集成时，我开始每约 15 秒（一周内 154K 次）发现重复性错误。

Error: Cannot GET /

打印：

我认为原因是我的 Node.js 应用程序在路由中使用了 /v1 前缀，即 / 路由不存在。

PS：Rollbar 在开发（本地）、测试（Heroku）和生产（GKE）环境中链接，错误仅发生在生产中。

我的入口文件：

apiVersion: extensions/v1beta1
kind: Ingress
Metadata:
    name: ingress-app
spec:
    rules:
        - host: api.company.com
          http:
              paths:
                  - path: /v1
                    backend:
                        serviceName: company-prod-v1-service
                        servicePort: 3000

Ingress 文档 says something about / endpoint，但我不太明白。

我需要删除这个错误。有哪位绝地大师能帮我解决这个错误吗？

提前致谢
