docker hub 加速器 nginx 配置 要求

加速器只允许 GET HEAD 请求方法

只允许docker-library/official-images通过加速器

控制允许通过加速器的路径，自己用自己配置map选项即可

docker-compose 配置

}

阻止服务被滥用的办法： nginx IP地址白名单机制

在nginx的 default.conf 文件中添加如下配置
IP 白名单机制
下面介绍2种方法

# 方法一： 

# 允许通过的白名单
map $remote_addr $allow_client_ip_flag {
     default 0;
    '42.83.144.13'   1;
}



# 白名单以外的IP地址处理逻辑
if ( $allow_client_ip_flag != 1) {
     return 403 '{"status":"403","result":"ip is refused","message":"403"}';
}

# 方法二：

    allow 192.168.1.0/24;
    allow 10.0.0.0/8;
    allow 172.16.0.0/12;

    allow 42.83.144.13;
    deny all;

备注

nginx的 这些配置项可以不要

        proxy_set_header User-Agent $http_user_agent;
        proxy_pass_request_headers  on;
        proxy_pass_request_body  on;
        proxy_read_timeout 30s;
        proxy_send_timeout 30s;
        proxy_http_version 1.1;

        proxy_ssl_protocols TLSv1.2 TLSv1.3;
        proxy_ssl_verify off;
        proxy_ssl_session_reuse on ;
        proxy_ssl_server_name on ;

辅助工具，获取nginx 默认配置文件

#!/bin/bash

set -eux
__CURRENT__=`pwd`
__DIR__=$(cd "$(dirname "$0")";pwd)
cd ${__DIR__}

 mkdir -p conf
container_id=$(docker create nginx:alpine)  # returns container ID
docker cp $container_id:/etc/nginx/nginx.conf conf/nginx.conf
docker cp $container_id:/etc/nginx/mime.types conf/mime.types
docker cp $container_id:/etc/nginx/conf.d/default.conf conf/default.conf

docker rm $container_id
