问题：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)

解决

方法一：换源

修改docker配置文件

vi /etc/docker/daemon.json

换成阿里云加速器的地址

"registry-mirrors":[" "]

重启docke

systemctl restart docker

方法二：手动指定仓库

指定仓库

docker pull 仓库名/镜像名:版本号
