安装Docker 脚本
适用于ubuntu和Centos系统，docker_version参数可根据自己的需求进行修改。
本文参考rancher官网，规避安装docker的繁琐步骤。

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker $your_user
Remember that you will have to log out and back in for this to take effect!
WARNING: Adding a user to the "docker" group will grant the ability to run
containers which can be used to obtain root privileges on the
docker host.
Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
