docker: Error response from daemon: Get “https://registry-1.docker.io/v2/“: context deadline exceed

在执行docker -run 的时候报错，

docker: Error response from daemon: Get “https://registry-1.docker.io/v2/”: context deadline exceeded (Client.Timeout exceeded while awaiting headers).

刚开始使用的是阿里的镜像源，但是不行
所以在网络上找了很多，终于找到有效的镜像源了
亲测有效！！！

{
"registry-mirrors": [
"https://docker.nju.edu.cn",
"https://hub.littlediary.cn",
"https://hub.xdark.top",
"https://dockerpull.org",
"https://hub.crdz.gq",
"https://docker.1panel.live",
"https://docker.unsee.tech"
]
}

所有命令，可以直接挨个执行

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
 {
 "registry-mirrors": [
"https://docker.nju.edu.cn", 
"https://hub.littlediary.cn",
"https://hub.xdark.top",
"https://dockerpull.org",
"https://hub.crdz.gq",
"https://docker.1panel.live",
"https://docker.unsee.tech"
]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
