MongoDB不能在Docker中使用Symfony應用程序

Question

我有一個在Docker容器中運行的REST API的Symfony應用程序。

所有路線的作品，但是當我試圖訪問一個路由數據庫，從數據庫中添加信息或提取信息，我收到

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. 

泊塢窗，撰寫文件創建的*與PHPDocker消息是

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_PORT: 27017 
    working_dir: /application 
    volumes: 
     - .:/application 
     - ./phpdocker/php-fpm/php-ini-overrides.ini:/etc/php5/fpm/conf.d/99-overrides.ini 

*我試圖添加鏈接到mongo圖片，但不起作用。

命令結果docker-compose up。

登錄時，我試圖從應用程序訪問一個簡單的頁面(localhost:8000) - 這是確定

code-php-fpm | 172.19.0.4 - 22/Apr/2017:23:24:52 +0000 "GET /app.php" 200

登錄，當我試圖訪問一個網址(localhost:8000/transactions/user=invalid&day=1492453903&threshold=100)有效，但與無效數據 - 這是確定

code-php-fpm | 172.19.0.4 - 22/Apr/2017:23:23:32 +0000 "GET /app.php" 400

當我嘗試接受日誌時SS的URL (localhost:8000/transactions/user=100&day=1492453903&threshold=100)與來自Mongo的數據庫中插入一個有效的數據有效 - 也不行

code-php-fpm | 172.19.0.4 - 22/Apr/2017:23:13:09 +0000 "GET /app.php" 500

來自Symfony項目的日誌：

當我試圖用Robomongo查看數據庫localhost:27017的作品。

有什麼建議嗎？ 謝謝！

Answer 1

兩個問題：

1. 你的nginx的服務器，而不是PHP/symfony的服務器
2. 您的鏈接也nginx的服務器上設置環境變量。 好消息是docker-compose的新版本不再要求您再使用鏈接。 docker-compose默認爲您的項目創建橋樑網絡。在這個橋接網絡上運行的所有服務都可以默認連接到對方。

我擺脫了這些link塊，並將環境變量從nginx移到php。
