Symfony

Add a service from your Symfony repo. Nixpacks detects php from composer.json. A Dockerfile in the service root always wins.

A Dockerfile with php-fpm is more typical. Set APP_ENV=prod and APP_SECRET.

Deploy from GitHub

1. Dashboard → New project (or open an existing canvas).
2. + Service → Git repository. Pick the repo and branch.
3. Review staged changes and Deploy.
4. Generate a *.stackblaze.app domain, or attach a custom domain.

Override install / build / start on the service if detection is wrong. Typical start: php -S 0.0.0.0:$PORT -t public.

Docker

If you already have a Dockerfile, StackBlaze uses it. The process must listen on PORT.

Data

+ Service → Databases for Postgres, Redis/Valkey, MySQL, and others. Wire DATABASE_URL from the service Variables tab or fromDatabase in stackblaze.yaml.
