minikube ingress

host(win) -> nginx -> vm(centos) -> docker(minikube) -> ingress-controller -> ingress -> svc -> pod
host(win) -> nginx -> vm(centos) -> docker(minikube) -> ingress-controller -> ingress -> svc.externalname -> svc.k8_dash -> pod

win.chrome:

http://all.minikube.cn/dash/  http://all.minikube.cn/dash  为什么不一样啊
多个/就行...
搞不明白 还是域名好用啊 虽然多一步加dns, 不过简单直接. path虽然灵活, 但规则配置不好就崴泥了. 另外不知道是什么原因. 

转kubernetes-dashboard的时候得把后面的path保留 用hello-app就啥事都没.. 


query-exporter也是一样的情形, 需要 metrics那个path
应该和应用的行为有关
