Question

有点背景是我已经设置了Azure Kubernetes服务群集并部署了基本的.Net Core api作为部署对象。然后，我部署了一个节点端口服务以公开api，然后部署了一个nginx-controller和一个入口对象来对其进行配置。我使用入口控制器的IP路由请求，并且可以正常工作，例如http://1.2.3.4/hello-world-one/api/values。但是，当我用生成的dns替换Ip时，以某种方式忽略了该路径，并且得到了默认的后端-从nginx控制器返回的404。预期的行为是dns将解析，然后将路径“ api / values”发送到我的服务。

有人可以帮我吗？预先感谢。

我的部署，服务和入口配置如下。

非常确定rules应该看起来像这样：

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
