Ubuntu-16.04下Docker通过阿里云镜像安装（apt-get）

由于通过官方路径安装docker时总是连接不上，所以从网上找了半天，通过阿里云镜像安装docker，我的Linux是ubuntu-16.04

一、配置源里的阿里云镜像仓库

sudo vim /etc/apt/sources.list

添加以下仓库

deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
添加完后执行

sudo apt update

更新源

二、安装装一些必要工具

sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common

三、安装docker

1.安装gpe证书

curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

2.写入软件源

sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"

3.更新源

sudo apt-get -y update

4 安装docker

4.1安装最新的docker

sudo apt-get install docker-ce

4.2安装指定版本docker

（1）查看docker版本

apt-cache madison docker-ce

docker-ce | 17.03.0~ce-0~ubuntu-xenial | http://mirrors.aliyun.com/docker-ce/linux/ubuntu xenial/stable amd64 Packages
 版本号是第一个竖线和第二个竖线之间的 ：  18.06.0~ce~3-0~ubuntu 

（2）安装制定版本docker

sudo apt-get install docker-ce=18.06.0~ce~3-0~ubuntu

5.安装校验

sudo docker version
