#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

hub.docker.com 被ban了 
现在用的办法是指定mirrors 让他不去默认的hub.docker 实在不行再proxy 但是不是好办法

containerd 配置代理

containerd 的配置一般位于 /etc/containerd/config.toml 下，service 文件位于：/etc/systemd/system/containerd.service 配置 Proxy 可以通过 service 环境变量方式配置，具体如下：

创建或编辑文件：/etc/systemd/system/containerd.service.d/http-proxy.conf

# 创建 containerd.service.d 目录
$ mkdir /etc/systemd/system/containerd.service.d/

# 创建或编辑文件
$ cat > /etc/systemd/system/containerd.service.d/http-proxy.conf <<-EOF
[Service]
Environment="HTTP_PROXY=http://127.0.0.1:7890"
Environment="HTTPS_PROXY=http://127.0.0.1:7890"
Environment="NO_PROXY=noproxy_address>"
EOF

# 重启containerd
$ systemctl daemon-reload
$ systemctl restart containerd

</pre>

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+
