# ==============================================================================
# Dockerfile — Production Multi-Stage Build for SMM Panel
# ==============================================================================
# Stage 1 (assets): Builds Vite/Tailwind assets with Node.js
# Stage 2 (app): PHP 8.2 + Nginx + Supervisor + all required extensions
#
# Changes from original:
#  1. Added pdo_pgsql extension (PostgreSQL support — was missing)
#  2. Removed pdo_mysql (not needed if using PostgreSQL)
#  3. Added pgsql extension
#  4. Added proper OPcache PHP extension enable order
#  5. Created non-root www-data user for security
#  6. Added docker/php/www.conf copy (was missing in original)
#  7. Moved composer install AFTER copying source (layer cache optimization)
#  8. .dockerignore prevents .git, node_modules, .env from entering image
# ==============================================================================
