1. Domestic acceleration address
Docker China official image
https://registry.docker-cn.com
NetEase
http://hub-mirror.c.163.com
ustc
https://docker.mirrors.ustc.edu.cn
University of Science and Technology of China
https://docker.mirrors.ustc.edu.cn
Alibaba Cloud Container Service
https://cr.console.aliyun.com/
Click "Create my container image" on the homepage to get a dedicated image acceleration address, similar to "https://1234abcd.mirror.aliyuncs.com"
2. Add method
2.1 Add "https://registry.docker-cn.com" to the registry-mirrors array.
[root@localhost ~]# vim /etc/docker/daemon.json { "registry-mirrors": ["https://registry.docker-cn.com"] } [root@localhost ~]# systemctl restart docker.service
2.2 Use command mode to add
[root@localhost ~]# dockerd --registry-mirror=https://registry.docker-cn.com
