Docker for Mac OS. Symfony cache clear optimization

symfony-optimization-for-mac-os.md

How ist's work?

Leave cache and logs out of synchronize with host machine and we have zero cost overhead when cache has been recalculated

Apply Docker NFS optimization for MAC

Add ENV variables

PROJECT_NAME=my-project-name

# for linux
SYMFONY_CACHE_DIR=
SYMFONY_LOGS_DIR=
# for Mac OSX
SYMFONY_CACHE_DIR=/tmp/symfony
SYMFONY_LOGS_DIR=/tmp/symfony

Extend docker-compose file

services:
    php:
        container_name: ${PROJECT_NAME}_php
        image: php:7.2-fpm
        volumes:
            - app_volume:/app:rw
        environment:
            SYMFONY_CACHE_DIR: ${SYMFONY_CACHE_DIR}
            SYMFONY_LOGS_DIR: ${SYMFONY_LOGS_DIR}

Symfony 3 and lower

class AppKernel extends Kernel
{
    public function getCacheDir(): string
    {
        $cacheRootDir = (string) getenv('SYMFONY_CACHE_DIR');

        if (empty($cacheRootDir)) {
            return parent::getCacheDir();
        }

        return rtrim($cacheRootDir, '/') . '/cache/' . $this->environment;
    }

    public function getLogDir(): string
    {
        $logsRootDir = (string) getenv('SYMFONY_LOGS_DIR');

        if (empty($logsRootDir)) {
            return parent::getLogDir();
        }

        return rtrim($logsRootDir, '/') . '/logs';
    }
}

Symfony 4 and higher

class Kernel extends BaseKernel
{
    use MicroKernelTrait;

    public function getCacheDir(): string
    {
        $cacheRootDir = getenv('SYMFONY_CACHE_DIR') ?? $this->getProjectDir();
    
        return rtrim($cacheRootDir, '/') . '/var/cache/' . $this->environment;
    }

    public function getLogDir(): string
    {
        $logsRootDir = getenv('SYMFONY_LOGS_DIR') ?? $this->getProjectDir();
    
        return rtrim($logsRootDir, '/') . '/var/log';
    }
}
