Docker Hub 镜像加速器

# 一、概述 #

国内从 Docker Hub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。Docker 官方和国内很多云服务商都提供了国内加速器服务。

二、配置加速地址

Ubuntu 16.04+、Debian 8+、CentOS 7+

创建或修改 `/etc/docker/daemon.json`：

sudo mkdir -p /etc/docker
    sudo tee /etc/docker/daemon.json <<-'EOF'
    {
        "registry-mirrors": [
            "https://1nj0zren.mirror.aliyuncs.com",
            "https://docker.mirrors.ustc.edu.cn",
            "http://f1361db2.m.daocloud.io",
            "https://registry.docker-cn.com"
        ]
    }
    EOF
    sudo systemctl daemon-reload
    sudo systemctl restart docker

## 检查加速器是否生效 ##

命令行执行 `docker info`，如果从结果中看到了如下内容，说明配置成功。

Registry Mirrors:
     [...]
     https://registry.docker-cn.com/

## Docker Hub 镜像测速 ##

使用镜像前后，可使用 `time` 统计所花费的总时间。测速前先移除本地的镜像！

$ docker rmi node:latest
    $ time docker pull node:latest
    Pulling repository node
    [...]
    
    real   1m14.078s
    user   0m0.176s
    sys    0m0.120s
