docker 拉取不到镜像的问题：拉取超时

error pulling image configuration: download failed after attempts=6: dial tcp 31.13.94.10:443: i/o timeout

首先设置国内的镜像源：复制下面直接执行

sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'{"registry-mirrors": ["https://ox288s4f.mirror.aliyuncs.com","https://registry.docker-cn.com","http://hub-mirror.c.163.com","https://mirror.ccs.tencentyun.com"]
}EOF

sudo systemctl daemon-reload
sudo systemctl restart docker或者sudo service docker restart

 再拉取就快了
