sudo docker run hello-world
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
See 'docker run --help'.
Modify docker mirror source:
docker default source for foreign official source, the download speed is slow, the country can be changed to accelerate
Option One
Modify or add /etc/docker/daemon.json
# We /etc/docker/daemon.json
{
"registry-mirrors": ["http://hub-mirror.c.163.com"]
}
systemctl restart docker.service
Option II
Modify or add / etc / sysconfig / docker, after the OPTIONS variable additional parameter --registry-mirror = https: //docker.mirrors.ustc.edu.cn
# vi /etc/sysconfig/docker
OPTIONS='--selinux-enabled --log-driver=journald --registry-mirror=https://docker.mirrors.ustc.edu.cn'
Docker domestic source Description ( Tip: You can try a few sources ):
Docker official in China
https://registry.docker-cn.com
Netease
http://hub-mirror.c.163.com
China University of Science and Technology
https://docker.mirrors.ustc.edu.cn
Ali Cloud
https://pee6w651.mirror.aliyuncs.com
I finally resolved with the following programs:
Enter / etc / docker
See if there daemon.json. This is the default configuration file docker.
If there is no new construction, if any, modifications.
[root@zengmg docker]# vi daemon.json
{
"registry-mirrors": ["https://registry.docker-cn.com"，“http://hub-mirror.c.163.com"]
}
Save and exit.
Restart docker Service
service docker restart
success!
