# SITMUN Application Stack - Docker Compose Configuration
#
# ============================================================================
# Environment Configuration (.env files)
# ============================================================================
#
# This stack uses Docker Compose's environment file system:
#
# 1. .env (not committed) - Default development configuration
#    - At least should include COMPOSE_PROFILES
#    - Minimum content:
#      COMPOSE_PROFILES=postgres,dev
#
# 2. Profile files (profiles/*.env) - Predefined configurations
#    - development-postgres.env: Development with PostgreSQL + demo data
#    - development-oracle.env: Development with Oracle + demo data
#    - postgres.env: Production with PostgreSQL (minimal seed data)
#    - oracle.env: Production with Oracle (minimal seed data)
#
# Docker Compose reads files in this order (last wins):
#   .env → .env.local → Environment variables
#
# ============================================================================
# Quick Start
# ============================================================================
#
# Development (default):
#   cp profiles/development-postgres.env .env
#   docker compose up -d
#
# Production:
#   cp profiles/postgres.env .env
#   docker compose up -d
#
# Local customization:
#   echo "PUBLIC_PORT=8080" >> .env.local
#   docker compose up -d
#
# ============================================================================
# Default Configuration (from committed .env)
# ============================================================================
#
# Frontend:
#   - ENVIRONMENT=development (shows "development", source maps enabled)
#   - PUBLIC_PORT=9000 (http://localhost:9000)
#
# Backend:
#   - DATABASE_TYPE=postgres
#   - SITMUN_CONFIG_DIR=development/backend (42 changesets, extensive demo data)
#   - COMPOSE_PROFILES=postgres,dev (PostgreSQL + example demo database)
#
# Databases:
#   - PostgreSQL on port 9003 (docker host)
#   - Example demo DB on port 9005 (docker host)
#
# ============================================================================
