由于微服务架构以及 Docker 技术和 kubernetes 编排工具最近几年才开始逐渐流行,所以一开始的反向代理服务器比如 nginx、apache 并未提供其支持,毕竟他们也不是先知;所以才会出现 Ingress Controller 这种东西来做 kubernetes 和前端负载均衡器如 nginx 之间做衔接;即 Ingress Controller 的存在就是为了能跟 kubernetes 交互,又能写 nginx 配置,还能 reload 它,这是一种折中方案;而最近开始出现的 traefik 天生就是提供了对 kubernetes 的支持,也就是说 traefik 本身就能跟 kubernetes API 交互,感知后端变化,因此可以得知: 在使用 traefik 时,Ingress Controller 已经无卵用了!

确实,k8s的时代,ingress负载用traefik比nginx方便啊
