What Railpack detects
Railpack inspects the repository and picks the build for PHP / Laravel; most projects need no configuration. A Dockerfile in the repository always wins.
- composer.json with
laravel/framework - artisan
- public/index.php
- Builder
- Railpack (default)
- Start command
- php artisan migrate --force && php artisan serve --host=0.0.0.0 --port=$PORT
Derived by Railpack; override it in Settings → Deploy → Start command.
