Docker中安装Docker------ubuntu

今天有个需求，需要使用jenkins部署docker项目，由于我们的jenkins就是用docker部署的，所以jenkins本身所在的系统同就是精简版的。查了一番，终于安装成功。

1. 备份文件

   mv /etc/apt/sources.list /etc/apt/sources.list.bakup
   

2. 切换源

   sudo vim /etc/apt/sources.list
   
   
   # 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
   deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
   # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
   deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
   # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
   deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
   # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
   deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse
   # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse
   
   # 预发布软件源，不建议启用
   # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse
   # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse
   

3. 刷新

apt-get update

4. docker一键安装

    curl -sSL https://get.daocloud.io/docker | sh
