# TimeSafari Docker Compose Configuration
# Author: Matthew Raymer
# Description: Multi-environment Docker Compose setup for TimeSafari
#
# IMPORTANT: Build web assets first using npm scripts before running docker-compose
#
# Usage:
#   Development: npm run build:web:build -- --mode development && docker-compose up dev
#   Test: npm run build:web:build -- --mode test && docker-compose up test
#   Production: npm run build:web:build -- --mode production && docker-compose up production
#   Custom: BUILD_MODE=test npm run build:web:build -- --mode test && docker-compose up custom
#
# Environment Variables:
#   BUILD_MODE: development, test, or production (default: production)
#   NODE_ENV: node environment (default: production)
#   PORT: port to expose (default: 80 for production, 8080 for test)
#   ENV_FILE: environment file to use (default: .env.production)
#
# Note: For development, use npm run build:web directly (no Docker needed)

version: '3.8'
