Как дать контейнер в качестве аргумента сервисам

Это 2016 , вы можете использовать черту , которая поможет вам расширить один и тот же класс несколькими библиотеками.

Ваш объект, который будет обслуживать.

namespace AppBundle\Utils;

use iBasit\ToolsBundle\Utils\Lib\Container;

class myObject
{
    use Container;
}

Настройки вашего сервиса

 myObject: 
        class: AppBundle\Utils\myObject
        calls:
            - [setContainer, ["@service_container"]]

Позвоните в сервис в контроллере

$myObject = $this->get('myObject');
