docker-compose.yml

# Test Infrastructure
#
# Provides services needed for integration tests across the monorepo.
# Uses non-standard ports by default to avoid conflicts with other containers.
#
# Usage:
#   docker compose up -d        # Start all services
#   docker compose up redis -d  # Start only Redis
#   pnpm test                   # Run tests (services auto-detected via .env)
#   docker compose down         # Stop all services
#
# Ports are configurable via .env or environment variables:
#   PGPORT=5433 (default)  — PostgreSQL
#   REDIS_PORT=6380 (default) — Redis
