• docker client
• docker-compose

Docker Compose

docker run -p "80" --link some_fpm_container \
    --volumes-from some_data_container \
    -v ./config:/etc/nginx/conf.d \
    -e VIRTUAL_HOST=php7szczecin.docker nginx

# docker-compose.yml
application:
    image: iteraptor/symfony_app
    volumes:
        - ./:/var/www
    tty: true

fpm:
    image: php:5.6-fpm
    working_dir: /var/www
    expose:
        - "9000"
    volumes_from:
        - application

nginx:
    image: nginx
    ports:
        - "80"
    links:
        - fpm
    volumes_from:
        - application
    volumes:
        - ./config:/etc/nginx/conf.d
    environment:
        VIRTUAL_HOST: php7szczecin.docker

# docker-compose.php7.yml
fpm:
    image: php:7.0-fpm

It was fast...
