docker-compose.yml

# =============================================================
#  LeadIQ-AI — Docker Compose
#  Starts n8n and reuses the existing "n8n_data" Docker volume.
#
#  Usage:
#    docker compose up -d      # start in background
#    docker compose down       # stop (data is preserved in volume)
#    docker compose logs -f    # tail logs
#
#  All secrets and runtime config come from .env — nothing is hardcoded here.
#  Run: cp .env.example .env  then fill in your actual values before starting.
