客户端在等待请求时关闭连接在 supervisord 中尝试在 Lumen 中使用 monolog 登录时

Question

我试图将 php-fpm7 日志显示到通过 nginx 和 supervisord 运行的标准输出中。supervisord 标准输出显示以下消息：

web_1| 2019-11-22 21:52:30,742 DEBG 'nginx' stdout output:
web_1| 2019/11/22 21:52:30 [info] 10#10: *1 client closed connection while waiting for request, client: 10.11.12.13, server: 0.0.0.0:80
web_1| 2019-11-22 21:52:31,481 BLAT read event caused by <POutputDispatcher at 140523539721320 for <Subprocess at 140523539815888 with name nginx in state RUNNING> (stdout)>
web_1| 10.11.12.13 - - [22/Nov/2019:21:52:31 +0000] "GET /offers/all HTTP/1.1" 500 24984 "-" "PostmanRuntime/7.19.0"

终端中什么也没有显示，但服务用数据回答了请求。

这是我的配置：

docker-compose-dev.yml

services:
  # web server
  web:
    build: .
    working_dir: /app
    network_mode: bridge
    command: supervisord
    [...]

文件

services:
  # web server
  web:
    build: .
    working_dir: /app
    network_mode: bridge
    command: supervisord
    [...]

配置文件

FROM alpine

    apk add bash curl openssh git supervisor nginx php7 \
    [...other dependencies...]

logging.php (src/config)

http {

    access_log /dev/stdout;
    error_log /dev/stdout info;
    [...]
}

报价控制器.php

<?php
use Monolog\Formatter\JsonFormatter;
use Monolog\Handler\StreamHandler;

return [
    'default' => env('LOG_CHANNEL', 'single'),

    'channels' => [
        'single' => [
            'driver' => 'monolog',
            'name' => 'offer-service-log',
            'handler' => StreamHandler::class,
            'formatter' => JsonFormatter::class,
            'with' => [
                // 'stream' => storage_path('logs/lumen.log'),
                'stream' => 'php://stdout',
            ],
        ],
        'stdout' => [
            'driver' => 'monolog',
            'handler' => StreamHandler::class,
            'formatter' => JsonFormatter::class,
            'with' => [
                'stream' => 'php://stdout',
            ],
        ],
    ],
];

我启动容器的方式是这样使用的docker-compose：

docker-compose -f docker-compose-dev.yml up --build

我无法理解发生了什么并弄清楚如何诊断问题。

提前致谢。
