docker部署rancher踩坑篇

1、docker部署rancher2.6.4提示rancher must be ran with the --privileged flag when running outside of kubernetes 

解决方法：sudo docker run --privileged -d --restart=unless-stopped -p 9080:80 -p 9443:443 --name rancher rancher/rancher  改为此命令即可

2、rancher新增work，etcd和control提示etcd出错或者其他错误，若服务器之前安装过rancher，请执行一下操作后，重新部署即可
