# ---------------------------------------------------------------------------
# Hotel Management System - self-contained production image.
#
# One container runs:
#   * MariaDB (bound to 127.0.0.1 only; schema + demo seed imported on first
#     boot, data persisted in /var/lib/mysql)
#   * the PHP application (front controller via public/router.php) listening
#     on 0.0.0.0:${PORT} (platform-injected; default 8080)
#
# All configuration is read from environment variables (APP_*, DB_*,
# PAYSTACK_*, HUBTEL_*, MAIL_*, SMS_*) - the app's Env class checks the
# process environment, so no .env file is shipped in the image.
# ---------------------------------------------------------------------------

# ---- Stage 1: PHP dependencies (real Composer autoloader + PHPMailer) ------
# --ignore-platform-reqs: the composer image lacks pdo_mysql (installed in
# the runtime stage), which composer.json declares as a platform requirement.
