Create a new Symfony application

This document contains information on how creating a Symfony application with Docker in less than 5 minutes.

Installation

You can clone this repo to get the code directly:

$ git clone https://github.com/Federkun/docker-skeleton-php.git docker-symfony-demo
$ cd docker-symfony-demo

Once you have the code, you'll need to copy .env.dist to .env:

$ cp .env.dist .env

Then you can use Composer to ease the creation of a new symfony project:

$ rm -rf app/* && docker-compose run --rm -u $(id -u):$(id -g) php composer create-project symfony/framework-standard-edition .

As from Symfony3.2 you can use the value of the environment variables into you service container configuration, using the %env(MYSQL_DATABASE)% notation:

Composer will create a new Symfony Standard Edition application under the app/ directory.

A minimum configuration file to get your application running under Nginx is already provided from docker-skeleton-php. Remove the default.conf file and rename symfony.conf.example into symfony.conf:

$ rm sites/default.conf
$ mv sites/symfony.conf.example sites/symfony.conf

Now remove the access check from app/web/app_dev.php:

// This check prevents access to debug front controllers that are deployed by accident to production servers.
// Feel free to remove this, extend it, or make something more sophisticated.
if (isset($_SERVER['HTTP_CLIENT_IP'])
    || isset($_SERVER['HTTP_X_FORWARDED_FOR'])
    || !(in_array(@$_SERVER['REMOTE_ADDR'], ['127.0.0.1', '::1']) || php_sapi_name() === 'cli-server')
) {
    header('HTTP/1.0 403 Forbidden');
    exit('You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
}

After you deploy to production, make sure that you cannot access the app_dev.php

You can start the containers now:

$ docker-compose up -d

F.A.Q.

• How can I use Symfony's console?

  Symfony 3:

  $ docker-compose run --rm php php bin/console

  Symfony 2:

  $ docker-compose run --rm php php app/console
