docker + php-fpm:+ ngnix 502 错误网关 nginx/1.23.2

Question

嗨，我正在尝试用我的 docker-compose 午餐多个项目，每张图片都是我从头开始创建的 FROM debian:11 我的反应和表达完美运行，但我不知道为什么 ngnix 和 symfony 不能相互连接，如果有人知道是什么我得到一个 502 Bad Gateway nginx/1.23.2 的问题，当我在终端中使用我的 docker 构建时，我没有任何错误消息。

当您使用 docker 将 ngnix 与 php-fpm 连接时，我找到了我的问题的解决方案，就像您的虚拟机中有虚拟机一样，所以 docker 找到了它，但是当您通过他时不知道该怎么做：fastcgi_pass php-fpm: 9000 ; 您只需要像这样将 ngnix 重定向到 PHP-fpm docker 了解他需要将它们连接在一起
