FrankenPHP with Docker
FROM dunglas/frankenphp:php8.5
# add additional extensions here:
RUN install-php-extensions \

ENV FRANKENPHP_CONFIG="worker ./public/index.php"
RUN cp $PHP_INI_DIR/php.ini-production $PHP_INI_DIR/php.ini

Symfony 7.4 detects the worker mode see https:/

Tips
✓ Cloud ready: environment
variables for every configuration
✓ Log to stderr is a good practice
with containers
✓ Single container really helps with
pragmatic configuration
✓ Watch mode to restart the worker
in dev mode

NGINX vs FrankenPHP
Scaleway DEV1-S (2 vCPUs, 2
GB RAM)
Database Server: 2 vCPUs, 2
GB RAM, MySQL
Benchmark Tool: wrk (on a
separate DEV1-S instance)
Nginx + PHP-FPM:
pm.max_children = 15
FrankenPHP (Worker Mode):
worker.num = 36
