            root html;
            index index.html index.htm;
        }
    }

Copy ip2region_v4.xdb to nginx/config folder (rename name it to ip2region.xdb), then restart nginx, the region data stored in ip2region variable

nginx access log sample

{"remote_addr": "127.0.0.1", "region": "Reserved|Reserved|Reserved|0|0", "http_x_forwarded_for": ""}
{"remote_addr": "127.0.0.1", "region": "Reserved|Reserved|Reserved|0|0", "http_x_forwarded_for": ""}

Additionally, you can build the nginx dynamic module using the Dockerfile in the current directory.

• The buildx plugin is required to enable export functionality.

docker build -t export_so -o type=tar,dest=./so.tar .
# The final result is a dynamic module named ngx_http_ip2region_module.so.
tar xf so.tar && rm so.tar

usage of dynamic modules

# nginx.conf
load_module /etc/nginx/my-modules/ngx_http_ip2region_module.so;

http {
    # ...
    ip2region_db /etc/nginx/conf.d/ip2region_v4.xdb content;
    ip2region_db6 /etc/nginx/conf.d/ip2region_v6.xdb content;
    # ...
}
