由於通過官方路徑安裝docker時總是連線不上，所以從網上找了半天，通過阿里雲映象安裝docker，我的Linux是ubuntu-16.04

一、配置源裡的阿里雲映象倉庫

sudo vim /etc/apt/sources.list

新增以下倉庫

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 
 

新增完後執行

sudo apt update

更新源

二、安裝裝一些必要工具

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

三、安裝docker

1.安裝gpe證書

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

2.寫入軟體源

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 安裝docker

4.1安裝最新的docker

sudo apt-get -y install docker-ce

4.2安裝指定版本docker

（1）檢視docker版本

apt-cache madison docker-ce

 docker-ce | 18.06.0~ce~3-0~ubuntu | http://mirrors.aliyun.com/docker-ce/linux/ubuntu xenial/stable amd64 Packages

 docker-ce | 17.03.1~ce-0~ubuntu-xenial | http://mirrors.aliyun.com/docker-ce/linux/ubuntu xenial/stable amd64 Packages
 docker-ce | 17.03.0~ce-0~ubuntu-xenial | http://mirrors.aliyun.com/docker-ce/linux/ubuntu xenial/stable amd64 Packages
 

 版本號是第一個豎線和第二個豎線之間的 ：  18.06.0~ce~3-0~ubuntu 

（2）安裝制定版本docker

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

5.安裝校驗

sudo docker version
