就现在而言，docker版本已经更新到19.06。但是，在笔者使用criu做热迁移时，发现docker的checkpoint始终无法restore。后面笔者才发现，原来是docker版本的问题，将版本切换到17.06即可。此时就需要指定版本安装docker。
注意事项
-
以下操作均在
root下进行，所以笔者的命令不会出现sudo。若未切换到root，则需要使用如下命令切换到root。su root -
笔者的下载源已经换成阿里源。
1 安装前的准备
首先执行下面4条命令。
apt update
apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable"
输出信息如下。
root@ubuntu:~# apt update

Hit:2 http://mirrors.aliyun.com/ubuntu xenial-updates InRelease
Hit:3 http://mirrors.aliyun.com/ubuntu xenial-security InRelease
