目前仍可用的镜像(随时可能失效)
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'

sudo systemctl daemon-reload
sudo systemctl restart docker
使用 Nginx
需要有一台国外服务器, 按下面添加 Nginx 配置即可:
server {
listen 443 ssl;
server_name 域名;
ssl_certificate 证书地址;
ssl_certificate_key 密钥地址;
proxy_ssl_server_name on; # 启用SNI
ssl_session_timeout 24h;
ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256';
ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
location / {
proxy_pass https://registry-1.docker.io; # Docker Hub 的官方镜像仓库
proxy_set_header Host registry-1.docker.io;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
# 关闭缓存
proxy_buffering off;
# 转发认证相关的头部
proxy_set_header Authorization $http_authorization;
proxy_pass_header Authorization;
# 对 upstream 状态码检查，实现 error_page 错误重定向
proxy_intercept_errors on;
# error_page 指令默认只检查了第一次后端返回的状态码，开启后可以跟随多次重定向。
recursive_error_pages on;
# 根据状态码执行对应操作，以下为301、302、307状态码都会触发
#error_page 301 302 307 = @handle_redirect;
error_page 429 = @handle_too_many_requests;
}
#处理重定向
location @handle_redirect {
resolver 1.1.1.1;
set $saved_redirect_location '$upstream_http_location';
proxy_pass $saved_redirect_location;
}
# 处理429错误
location @handle_too_many_requests {
proxy_set_header Host 替换为在CloudFlare Worker设置的域名; # 替换为另一个服务器的地址
proxy_pass http://替换为在CloudFlare Worker设置的域名;
proxy_set_header Host $http_host;
}
}
使用代理
主要是设置让服务器的 docker 走代理
首先新建目录和文件
mkdir -p /etc/systemd/system/docker.service.d
vim /etc/systemd/system/docker.service.d/http-proxy.conf
然后在文件中粘贴以下内容, 注意代理地址需要换成你自己服务器的内网 ip 和代理端口
[Service]
Environment="HTTP_PROXY=http://192.168.8.125:10819"
Environment="HTTPS_PROXY=http://192.168.8.125:10819"
Environment="NO_PROXY=your-registry.com,10.10.10.10,*.example.com"
重启 docker
systemctl daemon-reload
systemctl restart docker
检查环境变量是否生效
systemctl show --property=Environment docker
使用 Cloudflare 反向代理
登录到Cloudflare控制台, 新建 worker, 在 worker.js 文件中输入以下代码, 注意需要自行修改代码中的域名
'use strict'
const hub_host = 'registry-1.docker.io'
const auth_url = 'https://auth.docker.io'
const workers_url = 'https://你的域名'
const workers_host = '你的域名'
const home_page_url = 'https://qninq.cn/file/html/dockerproxy.html'

addEventListener('fetch', e => {

.catch(err => makeRes('cfworker error:\n' + err.stack, 502))
e.respondWith(ret)
})

部署完成后，点击设置->触发器->添加自定义域，绑定自己的域名即可
