創建并編輯文件

[root@localhost ~]# cd /etc/docker/ [root@localhost docker]# [root@localhost docker]# ls key.json [root@localhost docker]#

# vi daemon.json

[root@localhost docker]# pwd /etc/docker [root@localhost docker]# [root@localhost docker]# cat daemon.json {"registry-mirrors": ["https://hub.daocloud.io"] }

或者

https://almtd3fa.mirror.aliyuncs.com為阿里云的加速地址。修改后，重啟docker

{"registry-mirrors": ["https://almtd3fa.mirror.aliyuncs.com"] }

?

重啟服務

# systemctl daemon-reload

# systemctl restart docker.service

驗證：
# docker info
