纯Nginx加速Docker镜像

记得之前有看网友发过docker registry搭建私人docker加速镜像的，不过这样做首先要装docker，还要拉取docker registry，最关键的是加速的仓库机器还要缓存文件。Nginx的加速相对来说简单一点了，直接上配置，其中示例域名换成自己的，SSL证书自行替换

server {
    server_name speedup.docker.com;

    listen 443 ssl;
    ssl_certificate /etc/letsencrypt/live/speedup.docker.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/speedup.docker.com/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

 
    location / {
        proxy_pass https://registry-1.docker.io;  
        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;               
        proxy_buffering off;
        proxy_set_header Authorization $http_authorization;
        proxy_pass_header  Authorization;
        proxy_intercept_errors on;
        recursive_error_pages on;
        error_page 301 302 307 = @handle_redirect;
    }
    location @handle_redirect {
        resolver 1.1.1.1;
        set $saved_redirect_location '$upstream_http_location';
        proxy_pass $saved_redirect_location;
    }
} 
server {
    if ($host = speedup.docker.com) {
        return 301 https://$host$request_uri;
    }

    listen 80;
    server_name speedup.docker.com;
    return 404;
}
