docker镜像源配置教程，以及解决安装好docker配置镜像源后，出现报错。Job for docker.service failed

Job for docker.service failed because start of the service was attempted too often. See "systemctl status docker.service" and "journalctl -xe" for details.

解决后效果：

1、进入/etc/docker目录

cd /etc/docker

2、创建daemon.json文件并配置镜像加速源，执行：vim  /etc/docker/daemon.conf，粘贴一下内容进daemon.conf文件。

vim  /etc/docker/daemon.json

{"registry-mirrors": ["https://docker.m.daocloud.io","https://docker.imgdb.de","https://docker-0.unsee.tech","https://docker.hlmirror.com","https://docker.1ms.run","https://func.ink","https://lispy.org","https://docker.xiaogenban1993.com"]
}

3、执行systemctl daemon-reload 让镜像源配置生效。

systemctl daemon-reload

4、重启docker服务，执行systemctl restart docker

systemctl restart docker

5、执行docker info 检查配置是否神效

docker info
