How to Retrieve Configurations such as config.yml in a Template on Symfony2

I know that the controller can retrieve the value set to parameters in config.yml by $this->container->getParameter(), but is it not possible to retrieve it directly from the template?

For the symfony.1 series, I think I could get it through sfConfig::get('sf_category') etc., but if you can do something similar, please tell me how to do it.

If you want to get parameters from the template (Twig), you must register it in the global variable of twig yourself.

It's in English, but this area is helpful.
http://symfony.com/doc/current/cookbook/templating/global_variables.html

Or create your own TwigExtension
http://docs.symfony.gr.jp/symfony2/cookbook/templating/twig_extension.html

Another method is to implement the getGlobals() method.
http://twig.sensiolabs.org/doc/advanced.html#id1

If it is troublesome to set up parameters one by one, I think it would be better to implement them as follows.

ex.)
services.yml

services:
    app.twig_extension:
        class:AppBundle\Twig\AppExtension
        public —false
        arguments:
            - "@=service('service_container').parameters().all()"
        tags:
            - {name:twig.extension}

Create twig extension

class AppExtension extensions\Twig_Extension
{
    private$params;
    public function__construct(array$params)
    {
        $this->params=$params;
    }
    public function getGlobals()
    {
        return ['params' =>$this->params];
    }
}
