1.现象

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
Using default tag: latest
Trying to pull repository docker.io/library/centos ...
latest: Pulling from docker.io/library/centos
8ba884070f61: Pull complete

Status: Downloaded newer image for docker.io/centos:latest
[root@localhost docker]#

 3.验证

[root@localhost docker]# docker images

docker.io/centos    latest              9f38484d220f        10 days ago        202 MB
[root@localhost docker]#
