# =============================================================================
# Sub2API Docker Compose Host Configuration (Local Build)
# =============================================================================
# Quick Start:
#   1. Copy .env.example to .env and configure
#   2. docker-compose -f docker-compose-host.yml up -d --build
#   3. Check logs: docker-compose -f docker-compose-host.yml logs -f sub2api
#   4. Access: http://localhost:8080
#
# This configuration builds the image from source (Dockerfile in project root).
# All configuration is done via environment variables.
# No Setup Wizard needed - the system auto-initializes on first run.
