How can I run symfony 2 run command from controller

Register your command as a service and don't forget to call setContainer

MyCommandService:
    class: MyBundle\Command\MyCommand
    calls:
        - [setContainer, ["@service_container"] ]

In your controller, you'll just have to get this service, and call the execute method with the rights arguments

Set the input with setArgument method:

$input = new Symfony\Component\Console\Input\ArgvInput([]);
$input->setArgument('arg1', 'value');
$output = new Symfony\Component\Console\Output\ConsoleOutput();

Call the run method of the command:

$command = $this->get('MyCommandService');
$command->run($input, $output);

You can just simply create an instance of your command and run it:

/**
 * @Route("/run-command")
 */
public function someAction()
{
    // Running the command
    $command = new YourCommand();
    $command->setContainer($this->container);

    $input = new ArrayInput(['--your_argument' => true]);
    $output = new ConsoleOutput();

    $command->run($input, $output);

    return new Response();
}

See official documentation on this issue for newer versions of Symfony

You don't need services for command execution from controller and, I think, it is better to call command via run method and not via console string input, however official docs suggest you to call command via it's alias. Also, see this answer. Tested on Symfony 2.1-2.6.

Your command class must extend ContainerAwareCommand

// Your command

use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;

class MyCommand extends ContainerAwareCommand {
    // …
}


// Your controller

use Symfony\Component\Console\Input\ArrayInput;
use Symfony\Component\Console\Output\NullOutput;

class SomeController extends Controller {

    // …

    public function myAction()
    {
        $command = new MyCommand();
        $command->setContainer($this->container);
        $input = new ArrayInput(array('some-param' => 10, '--some-option' => true));
        $output = new NullOutput();
        $resultCode = $command->run($input, $output);
    }
}

In most cases you don't need BufferedOutput (from Jbm's answer) and it is enough to check that $resultCode is 0, otherwise there was an error.

In my environment ( Symony 2.1 ) I had to do some modifications to @Reuven solution to make it work. Here they are:

Service definition - no changes.

In controller:

use Symfony\Component\Console\Input\ArgvInput;
use Symfony\Component\Console\Output\ConsoleOutput;

...

public function myAction() {
    $command = $this->get('MyCommandService');

    $input = new ArgvInput(array('arg1'=> 'value'));
    $output = new ConsoleOutput();

    $command->run($input, $output);
}
