#Aug 19 2024 
原因在此

The Forbidden error occurs if the url is is not accessible, in this case https://production.cloudflare.docker.com/.

All the below urls have to be whitelisted behind a proxy / firewall.

    https://auth.docker.io
    https://registry-1.docker.io
    https://production.cloudflare.docker.com




2024 要login hubdocker 可能得代理才行

配置mirrors 改了dns 也是这样  代理 是最快的办法  可能不是最好的 

cat  /etc/systemd/system/docker.service.d/http-proxy.conf

国内从 Docker Hub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。Docker 官方和国内很多云服务商都提供了国内加速器服务。 配置加速地址

Ubuntu 16.04+、Debian 8+、CentOS 7+

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": [
        "https://1nj0zren.mirror.aliyuncs.com",
        "https://docker.mirrors.ustc.edu.cn",
        "http://f1361db2.m.daocloud.io",
        "https://registry.docker-cn.com"
    ]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
