如果直接 docker pull CentOS 两个小时才 down 下来 8M,很慢
2. 解决
[root@localhost network-scripts]# cd /etc/docker
[root@localhost docker]# ls
certs.d daemon.json key.json seccomp.json
[root@localhost docker]# cat daemon.json
{}
[root@localhost docker]# vi daemon.json
{
“registry-mirrors”: [“https://mj9kvemk.mirror.aliyuncs.com”]
}
重启 docker
[root@localhost docker]# service docker restart
Redirecting to /bin/systemctl restart docker.service
[root@localhost docker]#
重新拉取,秒秒钟
[root@localhost docker]# docker pull centos
