NGINX docker image that integrates with php-fpm

This image is for easily integrate nginx with php-fpm images. You should export php project's static files in a volume that shall be read by this image. Then some variables must be set for integration:

• ROOT: nginx document root. Where assets are published
• PHP_INDEX_FILE: it always is index.php, but you can set it with your php script file name
• PHP_FILES: which php script files will be allowed to execute
• PHP_UPSTREAM: upstream container name and port to access FPM service
• PHP_ROOT: document root for php-fpm script. It can be different than
• NGINX_GLOBAL_CONFIG: allows you to add custom nginx config at http {} block level document_root

Example usage

The following is a sample symfony 1.4 application

version: '2'
volumes:
  app-www:
  app-db:
services:
  app:
  # this image is created from php:fpm
  # application code will be inside /app
  # symfony's app/web directory will be copied to /web using cp -arL so
  # symlinks are removed and files can be accede by nginx:
  #   chown www-data:www-data /web && rm -fr /web/* && cp -arL /app/web/* /web/
    image: my-fpm-based-image
      DB_NAME: my_app
      DB_HOST: db
      DB_USERNAME: root
      DB_PASSWORD: root_pass
    volumes:
      - app-www:/web
  nginx:
    image: cespi/nginx-fpm:1.13
    environment:
      ROOT: /web
      PHP_INDEX_FILE: index.php
      PHP_FILES: index
      PHP_UPSTREAM: app:9000
      PHP_ROOT: /app/web
      NGINX_GLOBAL_CONFIG: 'set_real_ip_from 10.42.0.0/16;'
    ports:
      - "8080:80"
    volumes:
      - app-www:/web
  db:
    image: mysql:5.5
    environment: 
      MYSQL_DATABASE: my_ap
      MYSQL_ROOT_PASSWORD: root_pass
