### Rancher托管基于GKE搭建的k8s集群 ###

*  1、基于GKE搭建的k8s集群：
 *  2、部署Rancher
 *   *  2.1 部署Rancher前集群资源信息
     *  2.2 以docker 容器方式部署Rancher
     *  2.3 部署Rancher后集群资源信息
     *  2.4 Try一下

# 1、基于GKE搭建的k8s集群： #

[参考：1主2从基于GKE搭建k8s集群-无需科学上网][1_2_GKE_k8s_-]

# 2、部署Rancher #

## 2.1 部署Rancher前集群资源信息 ##

## 2.2 以docker 容器方式部署Rancher ##

*  部署Rancher容器

> 需要确保宿主机80及443端口可用，由于uat-w1节点部署Nginx-Ingress-Controller已经占用了80及443端口，这里将rancher容器部署在uat-master节点上，Rancher版本v2.3.6

[root@uat-master ~]# sudo docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher:v2.3.6

> 以uat-master外网IP登录Rancher，首次登录会要求设置登录用户名、密码、serverUrl地址（默认为当前节点IP）

*  添加
