Nginx控制器无法工作的入口，地址丢失
我有一个Kubernetes集群，运行在一个1主服务器上，2个工作人员安装ob linux服务器上。我有一个HAProxy将我的请求转发给Nginx控制器。我的完整设置是在一个公司代理的后面。在此公司代理中启用DNS条目。请求将到达nginx控制器，但不会被转发到服务。我在许多教程中安装了入口控制器，其中包含了https://github.com/kubernetes/ingress-nginx中的文件。
我对堆栈溢出很陌生，所以如果我需要提供更多的具体信息，请告诉我。我希望有人能帮我解决我的问题，谢谢。

看一下“侵入”的定义，我发现它忽略了“入口”类。您可以将带注释的IngressClass定义为要使用的默认类，或者这可能是当前您的进题无法工作的原因。
一个宏类基本上是一个类别，它指定谁需要服务和管理这个宏，这是必要的，因为在一个集群中，您可以有多个宏控制器，每个控制器都有自己的规则和配置。
根据Kubernetes版本的不同，可以在ingress上定义ingress类(在V1.18之前)，例如：
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: example-ingress
annotations:
kubernetes.io/ingress.class: nginx
spec:
...或者使用一个完整的资源，然后引用到into中，如文档(https://kubernetes.io/docs/concepts/services-networking/ingress/#ingress-class)中所示
即使在Kubernetes的新版本中，旧的注释仍然可能被支持，这取决于控制器。
如果您不确定您应该使用什么入口类(这应该由控制器来定义)，您可能在安装它时决定使用一个类，或者使用默认的类(大多数情况下是nginx)。
