## 镜像加速器 ##

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。国内很多云服务商都提供了国内加速器服务，例如：

*  [Azure 中国镜像 https://dockerhub.azk8s.cn][Azure _ https_dockerhub.azk8s.cn]
 *  [(需登录账号获取)阿里云加速器（个人）][Link 1][https://oalqrqxl.mirror.aliyuncs.com][https_oalqrqxl.mirror.aliyuncs.com]
 *  [七牛云加速器 https://reg-mirror.qiniu.com][https_reg-mirror.qiniu.com]

## 配置[阿里云加速器][Link 2] ##

### 1. 安装／升级Docker客户端 ###

推荐安装1.10.0以上版本的Docker客户端

### 2. 配置阿里云个人镜像加速器 ###

针对Docker客户端版本大于 1.10.0 的用户

您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器

sudo mkdir -p /etc/docker
    sudo tee /etc/docker/daemon.json <<-'EOF'
    {
      "registry-mirrors": ["https://oalqrqxl.mirror.aliyuncs.com"]
    }
    EOF
    sudo systemctl daemon-reload
    sudo systemctl restart docker

MobaXterm实际操作：

[root@localhost etc]# sudo mkdir -p /etc/docker
    [root@localhost etc]# sudo tee /etc/docker/daemon.json <<-'EOF'
    > {
    >   "registry-mirrors": ["https://oalqrqxl.mirror.aliyuncs.com"]
    > }
    > EOF
    {
      "registry-mirrors": ["https://oalqrqxl.mirror.aliyuncs.com"]
    }
    [root@localhost etc]# sudo systemctl daemon-reload
    [root@localhost etc]# sudo systemctl restart docker
    [root@localhost etc]# systemctl status docker
