docker pull太慢

1.现象

如果直接docker pull CentOS 你会发现很慢

2.解决

[root@localhost network-scripts]# vi /etc/docker/daemon.json

{
"registry-mirrors": ["https://mj9kvemk.mirror.aliyuncs.com"]
}

重启docker

[root@localhost docker]# systemctl restart docker

重新拉取，秒秒钟

[root@localhost docker]# docker pull centos
Using default tag: latest
Trying to pull repository docker.io/library/centos ...
latest: Pulling from docker.io/library/centos
