How to invalidate container cache in Symfony2?

php, symfony

Solution

As per `CacheClearCommand`:

$filesystem   = $this->container->get('filesystem');
$realCacheDir = $this->container->getParameter('kernel.cache_dir');
$this->container->get('cache_clearer')->clear($realCacheDir);
$filesystem->remove($realCacheDir);

Directly call CacheClearCommand from code:

services.yml

clear_cache_command_service:
    class: Symfony\Bundle\FrameworkBundle\Command\CacheClearCommand
    calls:
       - [setContainer, ["@service_container"] ]

Than it's possible to do something like this (note that this will warmup the cache):

$clearCacheCommand = $this->container->get('clear_cache_command_service');
$clearCacheCommand->run(new ArgvInput(), new ConsoleOutput());

Problem

Part of my Symfony app configuration is being loaded from legacy database, so sometimes I need to invalidate container cache to make use of updated data. Is there any API to invalidate Symfony container cache programmatically?
