docker_0">问题：下载docker镜像超时

error pulling image configuration: download failed after attempts=6: dial tcp 202.160.128.205:443: i/o timeout

解决办法：配置daemon.json

[root@bogon aihuidi]# cat /etc/docker/daemon.json 

{"registry-mirrors": ["https://vm1wbfhf.mirror.aliyuncs.com","http://f1361db2.m.daocloud.io","https://hub-mirror.c.163.com","https://docker.mirrors.ustc.edu.cn","https://mirror.baidubce.com","https://ustc-edu-cn.mirror.aliyuncs.com","https://registry.cn-hangzhou.aliyuncs.com","https://ccr.ccs.tencentyun.com","https://hub.daocloud.io","https://docker.shootchat.top","https://do.nark.eu.org","https://dockerproxy.com","https://docker.m.daocloud.io","https://dockerhub.timeweb.cloud","https://docker.shootchat.top","https://do.nark.eu.org"]
}

重启docker

systemctl daemon-reload 
systemctl restart docker
