Coolify-doc-driven production hardening of the deploy stack:
- run the whole stack as non-root www-data; nginx on 8080 (non-privileged),
pid in /tmp, user directive dropped (Coolify routes to any port)
- docker/healthcheck.sh: hit real /health route via PHP (not just port probe)
- split OPcache config into docker/php/opcache.ini
- graceful shutdown: supervisord stopsignal/stopwaitsecs + worker stop_grace_period
- APCu intentionally not added (Symfony cache uses redis)
- DEPLOY.md: 8080 port, non-root, resource-limit guidance
Verified on linux/amd64: non-root uid=82, /health 200, migrations run,
worker process healthcheck OK.
