docker pull centos慢问题的解决方案

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 Digest: sha256:8d487d68857f5bc9595793279b33d082b03713341ddec91054382641d14db861 Status: Downloaded newer image for docker.io/centos:latest [root@localhost docker]#
