解决方法:
配置daemon.json文件
1)由于国内访问直接访问docker网速比较慢,拉取镜像的时间就会比较长。一般使用镜像加速或者直接从国内的一些平台镜像仓库上拉取,配置镜像加速registry-mirrors
2)配置insecure-registries:字面意思为不安全的仓库,通过添加这个参数对非https仓库进行授信,可以设置多个insecure-registries地址,以数组形式书写,地址不能添加协议头(http)
[root@centos101 docker]#cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://pee6w651.mirror.aliyuncs.com","http://hub-mirror.c.163.com"],
"insecure-registries":["hub.c.163.com","hub-auth.c.163.com","index.docker.io"]
}
保存退出,执行:
systemctl daemon-reload
service docker restart
