报错Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http"或者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)

解决方案：

进入/etc/docker/daemon.json文件

加入一下配置：

{
  "registry-mirrors": ["https://docker.registry.cyou",
"https://docker-cf.registry.cyou",
"https://dockercf.jsdelivr.fyi",
"https://docker.jsdelivr.fyi",
"https://dockertest.jsdelivr.fyi",
"https://mirror.aliyuncs.com",
"https://dockerproxy.com",
"https://mirror.baidubce.com",
"https://docker.m.daocloud.io",
"https://docker.nju.edu.cn",
"https://docker.mirrors.sjtug.sjtu.edu.cn",
"https://docker.mirrors.ustc.edu.cn",
"https://mirror.iscas.ac.cn",
"https://docker.rainbond.cc"]
}

然后重启

systemctl daemon-reload

systemctl restart docker

如果安装了Docker的GUI，需要在客户端docker engine里面也同样加入该配置，保证统一

然后apply&restart

最后拉取镜像即可

亲测成功
