Question

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

所有路由都有效但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

*我试图添加到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工作时使用Robomongo查看数据库。

有什么建议吗？谢谢！

两个问题：

您在nginx服务器而不是php / symfony服务器上设置环境变量
您的链接也在nginx服务器上。好消息是较新版本的docker-compose不再要求您使用链接。 docker-compose默认为您的项目创建桥接网络。在此桥接网络上运行的所有服务都可以默认相互连接。

我摆脱了这些link块并将环境变量从nginx移到了php。

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

MongoDB不能与Docker中的Symfony应用程序一起使用
