Nginx-proxy docker从php-fpm docker接收stderr输出（导致502个错误）

Question

我有一个（相当标准的）设置，其中nginx-proxy提供静态文件，并将php请求发送到php-fpm Docker。合成文件的简化版本：

services:
  php:
    image: php:7-fpm-alpine
    volumes:
      - ./my-src:/var/www
  web:
    image: nginx:alpine
    volumes:
      - ./my-src:/var/www
    ports:
      - "80:80"

如果我调整/usr/local/etc/php-fpm.d/docker.conf中的设置，使error_log和access.log不是按照默认指向/proc/self/fd/2，而是指向/dev/null，php docker将保持沉默，但是nginx docker仍然返回错误。

如果我按照这里的建议将文件指向/proc/self/fd/2，那么两个日志都会像以前一样被填充。

如何确保php docker中的日志保持不变，但stderr没有发送到Nginx？

[编辑]根据Ilia Yatsenko的评论，我在DockerFile中添加了以下内容：

RUN cp "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini"
RUN echo 'fastcgi.logging=0' >> "$PHP_INI_DIR/php.ini"

我已经有一段时间没有在Docker设置中配置alpine php-fpm了，但是如果我没有记错的话，我必须对默认的php-fpm.conf进行一些重写。

这是我在类似的设置中所拥有的...在构建映像时，配置被复制到/etc/php7/php-fpm.conf。
