How to set the environment in a Symfony2 console command

Question

Hopefully a simple question - how does one specify which environment to use when running a console command in Symfony2. I\'ve created a few commands, however I would like to run

Answer 1

Maybe you could look at the implementation of the cache:clear command. This may give you some clues on how to choose the environment from a command.

app/console help cache:clear

Answer 2

To answer the question @croca had, to expand on what @Francesc Rosàs posted, and as @Problematic suggested.

If you look in app/console you should see $env = $input->getParameterOption(array('--env', '-e'), getenv('SYMFONY_ENV') ?: 'dev');

All this does is checks the input arguments passed to the console for --env or -e, checks the default value from getenv('SYMFONY_ENV'), or sets it to dev if neither are supplied.

It is then passed to $kernel = new AppKernel($env, $debug);

You could essentially either make changes directly to app/console to achieve your application's specific functionality or copy app/console to a separate file such as app/exec, then process the $env variable how you prefer to determine the desired environment.

Simple Example: app/exec

#!/usr/bin/env php
<?php
 /**
  * disabled debug mode, 
  * set environment based on requesting address being local 
  * otherwise the server's IP address
  * be sure to perform at least chmod(750) on the file to ensure it is executable
  * otherwise it must be prefixed with your php executable
  */     

set_time_limit(0);

require_once __DIR__.'/bootstrap.php.cache';
require_once __DIR__.'/AppKernel.php';

use Symfony\Bundle\FrameworkBundle\Console\Application;
use Symfony\Component\Console\Input\ArgvInput;

$input = new ArgvInput();
$env = ($_SERVER['REMOTE_ADDR'] === '127.0.0.1' || $_SERVER['REMOTE_ADDR'] === '::1' ? 'dev' :
    ($_SERVER['SERVER_ADDR'] === '192.168.2.1' ? 'test' : 'prod')
);
$kernel = new AppKernel($env, false);
$application = new Application($kernel);
$application->run($input);

Then call php app/exec namespace:command arguments --flags

Additionally you could process your own application instead of using the app/console AppKernel - instructions from Symfony can be found here: http://symfony.com/doc/current/components/console/introduction.html

Answer 3

There is another variant, not so convenient though, but works also with composer

SYMFONY_ENV=prod app/console cache:clear

Answer 4

You have two options that will help you out. You can specify the environment that the console will run in with the --env flag, and use --no-debug to disable debug mode.

php app/console --env=staging your:console:command or php app/console --env=prod your:console:command should do what you're looking for (the console runs in the dev environment with debug on by default).

You can look at the code of the app/console file for more info.

Answer 5

You can also use the SYMFONY_ENV environment variable to set a default environment distinct to 'dev' (e.g. export SYMFONY_ENV=prod in ~/.bash_profile)

Answer 6

The official documentation says:

By default, console commands run in the dev environment and you may want to change this for some commands.

So, as @Problematic suggest, you can specify the environment for your command using the flag "--env=your_env" or its shortcut "-e your_env".

I wonder whether it is possible to force the default environment for a command. I mean, without having to use the flags. Any idea?
