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

解決后效果：

1、進入/etc/docker目錄

cd /etc/docker

2、創建daemon.json文件并配置鏡像加速源，執行：vim? /etc/docker/daemon.conf，粘貼一下內容進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、執行systemctl daemon-reload 讓鏡像源配置生效。

systemctl daemon-reload

4、重啟docker服務，執行systemctl restart docker

systemctl restart docker

5、執行docker info 檢查配置是否神效

docker info
