MongoDB 不适用于 Docker 中的 Symfony 应用程序

Question

我有一个 Symfony 应用程序，用于在 Docker 容器中运行的 REST API。

所有路由都有效，但是当我尝试访问路由以在数据库中添加信息或从数据库中提取信息时，我会收到消息

Oops! An Error Occurred

The server returned a "500 Internal Server Error".

Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

使用PHPDocker 创建的docker-compose 文件是

version: "3.1"
services:
  mongo:
    image: mongo:3.0
    container_name: mongo
    command: mongod --smallfiles
    expose:
      - 27017

  webserver:
    tty: true
    image: phpdockerio/nginx:latest
    container_name: code-webserver
    working_dir: /application
    volumes:
        - .:/application
        - ./phpdocker/nginx/nginx.conf:/etc/nginx/conf.d/default.conf
    ports:
    - "8000:80"

  php-fpm:
    build:
      context: .
      dockerfile: phpdocker/php-fpm/Dockerfile
    container_name: code-php-fpm
    ### MOVE ENVIRONMENT VARIABLES HERE
    environment:
      SYMFONY__MONGO_ADDRESS: mongo
      SYMFONY__MONGO_PORT: 27017
    working_dir: /application
    volumes:
      - .:/application
      - ./phpdocker/php-fpm/php-ini-overrides.ini:/etc/php5/fpm/conf.d/99-overrides.ini

*我尝试添加指向 mongo 图像的链接，但不起作用。

命令docker-compose up的结果。

当我尝试在localhost:27017 上使用 Robomongo 查看数据库时。

有什么建议吗？ 谢谢！

Answer 1

两个问题：

1. 您在 nginx 服务器而不是 php/symfony 服务器上设置环境变量
2. 您的链接也在 nginx 服务器上。 好消息是docker-compose 的较新版本不再要求您使用链接。 docker-compose 默认为您的项目创建一个桥接网络。默认情况下，在此桥接网络上运行的所有服务都能够相互连接。

我摆脱了这些 link 块并将环境变量从 nginx 移动到 php。
