1、查看系统版本：

Docker需要Linux Kernels 大于3.10并且是64-bit的机器，用uname -a可以查看是否符合要求。

2、执行命令

编辑文本： vim /etc/apt/sources.list.d/backports.list, 加入以下代码：

deb http://http.debian.net/debian wheezy-backports main

然后刷新源： apt-get update
如果有安装过docker，则先删除旧版本docker

apt-get purge lxc-docker*

apt-get purge docker.io*

apt-get update

3、确认apt添加了https方法和CA cerificates

apt-get install apt-transport-https ca-certificates

4、添加一个新的GPG key

apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76

5、编辑文件：

vim /etc/apt/sources.list.d/docker.list, 因为Kali2.0是基于Debian Wheezy版本，所以加入下面代码：

deb https://apt.dockerproject.org/repo debian-wheezy main

On Debian Jessie

deb https://apt.dockerproject.org/repo debian-jessie main

On Debian Stretch/Sid

deb https://apt.dockerproject.org/repo debian-stretch main

保存后，然后更新： apt-get update

6、确认正确安装repository

apt-cache policy docker-engine

7、正式安装：

apt-get update

apt-get install docker-engine# 安装结束，打开docker服务

service docker start# 验证安装，运行测试样例

docker run hello-world# 如果没有错误就大功造成了！
