After solving the same problem for the fifth time I thought it was time to create a Bundle for this problem. I did again an extensive search on any other available material but I guess everybody is solving this problem on his own. On KnpBundles.com and Packagist.org I couldn't find any Bundle for this. So I created this one instead.

The problem: your staging environment indexed in Google

We all have some different environments for your apps (staging, test, dev) and we all have experienced this in the past: Google indexed your staging environment and every now and then a real visitor ends up there. Of course you can IP-block the staging but this isn't always feasible.

Solution for Symfony2: configurable robots.txt

Update your config.yml:

ricbra_robots_txt:
    allow_robots: %allow_robots%

In your parameters.yml file for production:

allow_robots: true

In your staging|dev|test parameters file:

allow_robots: false

Not really rocket science, but it works.

Installation

Composer ftw:

$ composer require ricbra/robots-txt-bundle

Then enable the bundle:

<?php
// app/AppKernel.php

$bundles = array(
    ...
    new Ricbra\Bundle\RobotsTxtBundle\RicbraRobotsTxtBundle(),
    ...
);

Update routing:

// app/config/routing.yml
ricbra_robots_txt:
    resource: "@RicbraRobotsTxtBundle/Resources/config/routing.yml"
    prefix:   /
