Symfony Framework

Symfony works out of the box in classic mode. For worker mode, override default FRANKENPHP_WORKER:

services:
  app:
    image: ghcr.io/adiachenko/frankenstack
    environment:
      PHP_ENV: development
      FRANKENPHP_MODE: worker
      FRANKENPHP_WORKER: /opt/project/public/index.php
    ports:
      - 8000:80
    volumes:
      - ./:/opt/project
    restart: unless-stopped

Worker lifecycle (start, reload, stop, metrics) is managed the same way as Laravel Octane — see Managing workers.
