关于镜像的版本与rancher版本、k8s版本有关。可以选择一个能够部署k8s 1.18的rancher版本：https://github.com/rancher/rancher/releases
比如我这里使用的是rancher v2.6.1，这个版本依赖的镜像，在官网https://github.com/rancher/rancher/releases/tag/v2.6.1 中找到依赖的镜像txt文件
比如我这里使用的是rancher_version=v2.5.2，这个版本依赖的镜像，在官网https://github.com/rancher/rancher/releases/tag/$rancher_version 中找到依赖的镜像txt文件
https://github.com/rancher/rancher/releases/download/v2.6.1/rancher-images.txt
https://github.com/rancher/rancher/releases/download/$rancher_version/rancher-images.txt
将依赖镜像在开发网拉取下来，然后重新tag成内网仓库镜像，例如docker.oa.com域名下的镜像，推送到docker.oa.com上，后面需要在idc每个机器上拉取下来，再tag成原始镜像名。例如
## 可以连接外网的机器上
docker pull rancher/rancher-agent:v2.6.1
docker tag rancher/rancher-agent:v2.6.1 docker.oa.com:8080/public/rancher/rancher-agent:v2.6.1
docker pull rancher/rancher-agent:$rancher_version
docker tag rancher/rancher-agent:$rancher_version docker.oa.com:8080/public/rancher/rancher-agent:$rancher_version
## 内网idc机器
docker pull docker.oa.com/public/rancher/rancher-agent:v2.6.1
docker tag docker.oa.com/public/rancher/rancher-agent:v2.6.1 rancher/rancher-agent:v2.6.1
docker pull docker.oa.com/public/rancher/rancher-agent:$rancher_version
docker tag docker.oa.com/public/rancher/rancher-agent:$rancher_version rancher/rancher-agent:$rancher_version
由于依赖镜像比较多，可以写一个脚本，批量的拉取和tag。
