默认后端 - 使用 dns 时从 nginx-controller 返回 404

Question

一点背景是我已经设置了一个 Azure Kubernetes 服务集群并部署了一个基本的 .Net Core api 作为部署对象。然后我部署了一个 nodeport 服务来公开 api，然后部署了一个 nginx-controller 和一个 ingress 对象来配置它。我使用入口控制器的 IP 来路由请求，例如工作。http://1.2.3.4/hello-world-one/api/values。但是当我用生成的 dns 替换 Ip 时，不知何故忽略了路径，我得到了默认后端 - 从 nginx 控制器返回的 404。预期的行为是 dns 将解析，然后路径“api/values”将被发送到我的服务。

谁能帮我这个？提前致谢。

我的部署、服务和入口配置如下。

很确定rules应该是这样的：

rules:
- host: hello-world-ingress.be543d4af69d4c7ca489.westus.aksapp.io
  http:
    paths:
    - path: /
      backend:
        serviceName: frontend
        servicePort: http
    - path: /hello-world-one
      backend:
        serviceName: frontend
        servicePort: http
    - path: /hello-world-two
      backend:
        serviceName: frontend
        servicePort: http
