1.操作步骤

# 建立设置文件存放目录
mkdir -p ~/nginx
# 预启动 echo header docker 容器，本地端口号 80
docker run -d --rm --name nginx_echo -p 80:8080 brndnmtthws/nginx-echo-headers
# 拷贝容器内 nginx 设置文件到本地
docker cp nginx_echo:/usr/local/openresty/nginx/conf ~/nginx

# 修改配置文件 nginx.conf
# 注意'$'需要添加转义符 
cat > ~/nginx/conf/nginx.conf << END
error_log stderr debug;

events {
    worker_connections 1024;
}

http {
    access_log off;
    include mime.types;

    server {
        listen 8080;

        location / {

          echo "
           {
              \"ua\": \"\$http_user_agent\",
              \"X-Real-IP\": \"\$remote_addr\",
              \"X-Forwarded-For\": \"\$proxy_add_x_forwarded_for\"
            }";

        }
    }
}
END

# 关闭容器
docker stop nginx_echo
# 重启容器，挂载配置文件
docker run -d --rm \
--name nginx_echo \
-v ~/nginx/conf:/usr/local/openresty/nginx/conf \
-p 80:8080 \
brndnmtthws/nginx-echo-headers

# 本地浏览器访问
➜ curl http://127.0.0.1

           {
              "ua": "curl/7.54.0",
              "X-Real-IP": "172.17.0.1",
              "X-Forwarded-For": "172.17.0.1"
            }

备注：

检查X-Forwarded-For是否会带有真实请求IP。

2.配置文件示例

修改镜像里的配置文件 /usr/local/openresty/nginx/conf/nginx.conf

error_log stderr debug;

events {
    worker_connections 1024;
}

http {
    access_log off;
    include mime.types;

    server {
        listen 8080;

        location / {
          echo "
           {
              \"ua\": \"$http_user_agent\",
              \"X-Real-IP\": \"$remote_addr\",
              \"X-Forwarded-For\": \"$proxy_add_x_forwarded_for\"
            }";
        }
    }
}

3.附录 nginx-echo-headers Docker 镜像

• https://github.com/brndnmtthw…

3.1 nginx-echo-headers/Dockerfile

FROM openresty/openresty:1.11.2.5-alpine

EXPOSE 8080
ADD nginx.conf /usr/local/openresty/nginx/conf/nginx.conf

RUN chgrp -R 0 /usr/local/openresty/nginx/ && \
    chmod -R g=u /usr/local/openresty/nginx/

3.2 nginx-echo-headers/nginx.conf

error_log stderr debug;

events {
    worker_connections 1024;
}

http {
    access_log off;
    include mime.types;

    server {
        listen 8080;

        location / {
          echo_duplicate 1 $echo_client_request_headers;
          echo "\r";
          echo_read_request_body;
          echo $request_body;
        }
    }
}
