# Simple setup script to bootstrap the Dockerized dev stack for this project.
# - Builds and starts containers (php, nginx, mariadb, mailpit via override)
# - Installs composer dependencies
# - Ensures APP_SECRET is set (generates if empty)
# - Creates and migrates the database
# - Installs/imports JS dependencies
# - Prints helpful info on success

# Usage:
#   ./docker/setup.sh            # full setup
#   ./docker/setup.sh --no-build # skip image rebuild
#   ./docker/setup.sh --down     # stop and remove containers (down)
#   ./docker/setup.sh --recreate # force recreate containers

Setup complete!

Open the app:      $APP_URL
Mailpit (dev):     $MAILPIT_URL

Common commands:
  (cd docker && $DOCKER_COMPOSE logs -f nginx)
  (cd docker && $DOCKER_COMPOSE logs -f php)
  (cd docker && $DOCKER_COMPOSE exec php bash)
  (cd docker && $DOCKER_COMPOSE down)

You can re-run this script any time. Use --no-build to skip rebuilding images.
