由于我的很多帖子都是使用docker-compose进行演示的，有些同学对此不是很熟悉，所以本文介绍一下如何在ubuntu上安装docker和docker-compose。

      一、apt更换为阿里源

Ubuntu16:

 (1) 备份 /etc/apt/sources.list

$: cp /etc/apt/sources.list /etc/apt/sources.list.bakcup

 (2)将以下内容写入/etc/apt/sources.list

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

Ubuntu14:

 (1) 备份 /etc/apt/sources.list

$: cp /etc/apt/sources.list /etc/apt/sources.list.bakcup

 (2)将以下内容写入/etc/apt/sources.list

deb http://mirrors.aliyun.com/ubuntu trusty main restricted
deb-src http://mirrors.aliyun.com/ubuntu trusty main restricted
deb http://mirrors.aliyun.com/ubuntu trusty-updates main restricted
deb-src http://mirrors.aliyun.com/ubuntu trusty-updates main restricted
deb http://mirrors.aliyun.com/ubuntu trusty universe
deb-src http://mirrors.aliyun.com/ubuntu trusty universe
deb http://mirrors.aliyun.com/ubuntu trusty-updates universe
deb-src http://mirrors.aliyun.com/ubuntu trusty-updates universe
deb http://mirrors.aliyun.com/ubuntu trusty multiverse
deb-src http://mirrors.aliyun.com/ubuntu trusty multiverse
deb http://mirrors.aliyun.com/ubuntu trusty-updates multiverse
deb-src http://mirrors.aliyun.com/ubuntu trusty-updates multiverse
deb http://mirrors.aliyun.com/ubuntu trusty-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu trusty-backports main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu trusty-security main
deb-src http://mirrors.aliyun.com/ubuntu trusty-security main
deb http://mirrors.aliyun.com/ubuntu trusty-security universe
deb-src http://mirrors.aliyun.com/ubuntu trusty-security universe

二、安装docker

$: sudo apt-get update

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

-- 安装GPG证书

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

-- 写入软件源信息

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

-- 更新并安装 Docker-CE

$: sudo apt-get -y update

$: sudo apt-get -y install docker-ce

-- 镜像加速

$: sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://f3zh23hq.mirror.aliyuncs.com"]
}
EOF 

$: sudo systemctl reload docker

官方参考： https://docs.docker.com/install/linux/docker-ee/ubuntu/

 

三、安装docker-compose

$: curl -L https://get.daocloud.io/docker/compose/releases/download/1.19.0/docker-compose-`uname -s`-`uname -m` | sudo tee /usr/local/bin/docker-compose > /dev/null

$: sudo chmod +x /usr/local/bin/docker-compose

可以根据需要选择适合自己的版本
