通过github yaml文件安装:V11目录代表安装ingress 1.11版本，自己建的方便区分.
切换到一下目录:
/root/v11/kubernetes-ingress/deployments/helm-chart
修改values.yaml配置文件:参数根据个人需要调整。
执行安装:【k8s nginx-ingress部署】helm install my-release .?
查看当前ingress-contro的ingress-class：[root@master helm-chart]# kubectl get deploy -n default -o yaml | grep class
