Ubuntu安装Docker并配置镜像

安装比较简单，这种安装的Docker不是最新版本，不过对于学习够用了，依次执行下面命令进行安装。

$ <span class="token function">sudo</span> <span class="token function">apt</span> <span class="token function">install</span> docker.io 
$ <span class="token function">sudo</span> <span class="token function">apt</span> <span class="token function">install</span> docker.io 
$ sudo apt install docker.io 

$ <span class="token function">sudo</span> systemctl start docker $ <span class="token function">sudo</span> systemctl <span class="token builtin class-name">enable</span> docker 
$ <span class="token function">sudo</span> systemctl start docker $ <span class="token function">sudo</span> systemctl <span class="token builtin class-name">enable</span> docker 
$ sudo systemctl start docker $ sudo systemctl enable docker 

查看是否安装成功

$ docker -v Docker version <span class="token number">17.12</span>.1-ce, build 7390fc6 
$ docker -v Docker version <span class="token number">17.12</span>.1-ce, build 7390fc6 
$ docker -v Docker version 17.12.1-ce, build 7390fc6 

这种安装方式首先要保证Ubuntu服务器能够访问Docker仓库地址：https://download.docker.com/linux/ubuntu，如果能够访问，按照下面的操作步骤进行安装。

$ <span class="token function">sudo</span> <span class="token function">apt</span> update $ <span class="token function">sudo</span> <span class="token function">apt</span> <span class="token function">install</span> apt-transport-https ca-certificates <span class="token function">curl</span> software-properties-common 
$ <span class="token function">sudo</span> <span class="token function">apt</span> update $ <span class="token function">sudo</span> <span class="token function">apt</span> <span class="token function">install</span> apt-transport-https ca-certificates <span class="token function">curl</span> software-properties-common 
$ sudo apt update $ sudo apt install apt-transport-https ca-certificates curl software-properties-common 

在/etc/apt/sources.list.d/docker.list文件中添加下面内容

deb <span class="token punctuation">[</span>arch<span class="token operator">=</span>amd64<span class="token punctuation">]</span> https://download.docker.com/linux/ubuntu bionic stable 
deb <span class="token punctuation">[</span>arch<span class="token operator">=</span>amd64<span class="token punctuation">]</span> https://download.docker.com/linux/ubuntu bionic stable 
deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable 

添加秘钥

$ <span class="token function">curl</span> -fsSL https://download.docker.com/linux/ubuntu/gpg <span class="token operator">|</span> <span class="token function">sudo</span> apt-key <span class="token function">add</span> - 
$ <span class="token function">curl</span> -fsSL https://download.docker.com/linux/ubuntu/gpg <span class="token operator">|</span> <span class="token function">sudo</span> apt-key <span class="token function">add</span> - 
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - 

安装docker-ce

$ <span class="token function">sudo</span> <span class="token function">apt</span> <span class="token function">install</span> docker-ce 
$ <span class="token function">sudo</span> <span class="token function">apt</span> <span class="token function">install</span> docker-ce 
$ sudo apt install docker-ce 

查看是否安装成功：

$ docker --version Docker version <span class="token number">18.03</span>.0-ce, build 0520e24 
$ docker --version Docker version <span class="token number">18.03</span>.0-ce, build 0520e24 
$ docker --version Docker version 18.03.0-ce, build 0520e24 

国内亲测可用的几个镜像源：

• Docker 官方中国区：https://registry.docker-cn.com
• 网易：http://hub-mirror.c.163.com
• 中国科技大学：https://docker.mirrors.ustc.edu.cn
• 阿里云：https://y0qd3iq.mirror.aliyuncs.com

增加Docker的镜像源配置文件 /etc/docker/daemon.json，如果没有配置过镜像该文件默认是不存的，在其中增加如下内容：

然后重启Docker服务：

<span class="token function">service</span> docker restart 
<span class="token function">service</span> docker restart 
service docker restart 

然后通过以下命令查看配置是否生效：

docker info<span class="token operator">|</span><span class="token function">grep</span> Mirrors -A <span class="token number">1</span> 
docker info<span class="token operator">|</span><span class="token function">grep</span> Mirrors -A <span class="token number">1</span> 
docker info|grep Mirrors -A 1 

可以看到如下的输出：

Registry Mirrors: https://y0qd3iq.mirror.aliyuncs.com/ 
Registry Mirrors: https://y0qd3iq.mirror.aliyuncs.com/ 
Registry Mirrors: https://y0qd3iq.mirror.aliyuncs.com/ 

就表示镜像配置成功，然后再执行docker pull操作，就会很快了。
