kubernetes traefik 2.x在ingress使用middlewares中间件

Traefik 路由规则及中间件 Traefik Middlewares 的配置
我百度了很多traefik的东西，就只有这篇东西里面提到了ingress里面怎么使用middlewares中间件，但是它没有提到traefik deployment的yaml怎么写。我就看到里面用了crd，但是没想到要用两个provider，最后终于猜出了要使用两个provider，一个- --providers.kubernetescrd和- --providers.kubernetesingress，然后还要用ingressroute的crd和rbac，这样才能在ingress里面运用中间件。
