我正在尝试这个例子，遇到了前面提到的非常愚蠢的问题。经过几个小时的尝试，我发现问题出在“匹配”规则上。

-match: PathPrefix(`/whoami-app-api`)
-match: Host(`whoami.localhost`) && PathPrefix(`/notls`)

无主机匹配将通过http:localhost工作/

有些主机喜欢真实的URI，比如abc.com，scx.net，浏览器会尝试通过DNS而不是本地主机“0.0.0.0”来访问它，所以它无法访问我们的Traefik。

否则，带有单个单词的主机也无法工作。我不知道为什么。我认为在URL中，至少有2个单词被点分隔

我部署了下面的代码，现在可以访问whoami，没有任何问题。我更改的内容是，使用Traefik中可用的最新版本更新CRD、RBAC，并将部署的apiVersion更改为“apps/v1”。只需将下面的代码一起复制并部署到kubernetes上。一旦启动访问http://localhost/whoami-app-api.

它为我的工作与treafik 2.1使用以下资源集。

你能试试这些吗？如果有用的话，请告诉我。

Kubernetes-入口路由工作原理

我看到了一些示例，其中Kubernetes集群安装了ingress控制器，然后ingress类添加了注释和主机，如下所示。我不确定安装了哪个服务，哪个IP配置了DNS“k8s.privatecoud.com”，以便路由请求？DNS路由“k8s.privatecoud.com”如何将请求路由到Kubernetes集群？kubernetes桥的入口是如何工作的？此外，可以使用主机规则配置许多服务，
