查看“DockerHub镜像加速和代理”的源代码

=2024=
<pre>
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

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+
