安装 Docker
0、更新 apt 源
1 /etc/apt/sources.list 2 # deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted 3 deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties 4 deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted 5 deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe #Added by software-properties 6 deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted 7 deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe #Added by software-properties 8 deb http://mirrors.aliyun.com/ubuntu/ xenial universe 9 deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe 10 deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse 11 deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse 12 deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse 13 deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse #Added by software-properties 14 deb http://archive.canonical.com/ubuntu xenial partner 15 deb-src http://archive.canonical.com/ubuntu xenial partner 16 deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted 17 deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe #Added by software-properties 18 deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe 19 deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse
1、配置安装Docker的apt源
a) 安装包，允许 apt 命令 HTTPS 访问 Docker 源。
1 sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
b) 添加 Docker 官方的 GPG
1 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
c)将 Docker 的源添加到 /etc/apt/sources.list
1 sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
2、安装 Docker
1 sudo apt-get update 2 sudo apt-get install docker-ce
运行第一个容器
环境就绪，马上运行第一个容器，执行命令：
1 docker run -d -p 80:80 httpd
启动 httpd 容器，并将容器的 80 端口映射到 host 的 80 端口。
本地测试
1 curl http://127.0.0.1:80
其过程为：
- 从 Docker Hub 下载 httpd 镜像。镜像中已经安装好了 Apache HTTP Server。
- 启动 httpd 容器，并将容器的 80 端口映射到 host 的 80 端口。
3、Docker下载加速器
由于 Docker Hub 的服务器在国外，下载镜像会比较慢。DaoCloud 为我们提供了免费的国内镜像服务。
- 在 daocloud.io 免费注册一个用户。
- 登录后，点击顶部菜单“加速器”。
- copy “加速器”命令并在 host 中执行。
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://53dc37d0.m.daocloud.io
- 重启 Docker deamon，即可体验飞一般的感觉。
systemctl restart docker.service
