一.问题描述

不知从何时起我的docker下载镜像特别的慢，上一次下载traefik没有很大就要2小时，换了各种网络还是那么慢（以前还是很快的）替换了镜像之后还是各种问题

[root@master154 docker]# systemctl daemon-reload

[root@master154 docker]# systemctl start docker

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

 systemctl restart docker.service

二.解决方案

1.到阿里云上申请自己镜像加速器

阿里云登录 - 欢迎登录阿里云，安全稳定的云计算服务平台

vi /etc/docker/daemon.json

{

    "registry-mirrors": ["https://awkamezj.mirror.aliyuncs.com"]

}

还有多种镜像地址可供参考

ustc：https://docker.mirrors.ustc.edu.cn

网易：http://hub-mirror.c.163.com

七牛：https://reg-mirror.qiniu.com

官方中国：https://registry.docker-cn.com

{

      "registry-mirrors": ["https://awkamezj.mirror.aliyuncs.com","https://docker.mirrors.ustc.edu.cn","http://hub-mirror.c.163.com","https://reg-mirror.qiniu.com","https://registry.docker-cn.com"]

}
 

然后执行下边命令重启docker

sudo systemctl daemon-reload

sudo systemctl restart docker

2.如果你的问题还存在

如果启动的时候还是报上边提到的一些异常，请检查下配置文件格式是否正确，/etc/docker/daemon.json文件中是否存在 # 注释，我就是那个傻子居然为了保留原来的镜像地址，在原来地址上添加了#注释，被自己蠢哭了

配置成功后就可以加速下载了！！！！！！！！！！
