我正在配置 docker-compose.yml 文件，我想运行一个包含 Elastic、Redis、Symfony 和 composer 的 PHP 堆栈。

现在我遇到的问题是，我不知道如何将 composer 与 docker 一起使用，因为 composer 的某些功能需要 PHP 和一些扩展。我不想构建一个新镜像并在其上安装 Nginx 和 PHP 以及 PHP 的 composer 和扩展，我不想将它们全部放在一个不同的镜像中。

到目前为止我尝试过的是这样的:

version : '2'

services:
  nginx:
    image: tutum/nginx
    ports:
        - "80:80"
    volumes:        
        - ./nginx/default:/etc/nginx/sites-available/default
        - ./nginx/default:/etc/nginx/sites-enabled/default
        - ./logs/nginx-error.log:/var/log/nginx/error.log
        - ./logs/nginx-access.log:/var/log/nginx/access.log
        - ./app:/usr/share/nginx/html

  phpfpm:
      image: php:fpm
      ports:
          - 9000:9000
      volumes:      
          - ./app:/usr/share/nginx/html
          
  composer:
      image: composer/composer:php7
      command: install
      volumes: 
        - ./app:/app

  elastic2.4.4:
    image: elasticsearch:2.4.4    
    ports:
      - 9200:9200
    volumes:
      - ./esdata1:/usr/share/elasticsearch/data

  redis:
    image: redis:3.2
    ports:
      - 6379:6379

但这不会安装依赖项。

最佳答案

我设置了我的 docker-compose.yml 文件，这样一个 docker 实例将使用 composer/composer 图像并在其中执行 composer install共享容器。然后所有其他图像都可以访问 Composer 创建的供应商目录。棘手的部分是意识到 composer/composer 图像假定 composer.json 文件将位于 /app 目录中。我不得不通过将我的共享容器指定为 working_dir 来覆盖此行为:

version: '3'

services:
  #=====================#
  # nginx proxy service #
  #=====================#
  nginx_proxy:
    image: nginx:alpine
    networks:
      - test_network
    ports:
      - "80:80"
      - "443:443"
    volumes:
      # self-signed testing wildcard ssl certificate
      - "./certs:/certs"
      # proxy needs access to static files
      - "./site1/public:/site1/public"
      - "./site2/public:/site2/public"
      # proxy needs nginx configuration files
      - "./site1/site1.test.conf:/etc/nginx/conf.d/site1.test.conf"
      - "./site2/site2.test.conf:/etc/nginx/conf.d/site2.test.conf"
    container_name: nginx_proxy

  #===============#
  # composer.test #
  #===============#
  composer.test:
    image: composer/composer
    networks:
      - test_network
    ports:
      - "9001:9000"
    volumes:
      - "./composer:/composer"
    container_name: composer.test
    working_dir: /composer
    command: install

  #============#
  # site1.test #
  #============#
  site1.test:
    build: ./site1
    networks:
      - test_network
    ports:
      - "9002:9000"
    environment:
      - "VIRTUAL_HOST=site1.test"
    volumes:
      - "./composer:/composer"
      - "./site1:/site1"
    container_name: site1.test

  #============#
  # site2.test #
  #============#
  site2.test:
    build: ./site2
    networks:
      - test_network
    ports:
      - "9003:9000"
    environment:
      - "VIRTUAL_HOST=site2.test"
    volumes:
      - "./composer:/composer"
      - "./site2:/site2"
    container_name: site2.test

# networks
networks:
  test_network:

目录结构如下:

certs
    test.crt
    test.key
composer
    composer.json
site1
    app
    public
    Dockerfile
    site1.test.conf
site2
    app
    public
    Dockerfile
    site2.test.conf
docker-compose.yml
