# =============================================================================
# Docker Compose — Stack 2.9 GPU Deployment
# =============================================================================
# Usage:
#   Start:  docker compose -f docker-compose.gpu.yml up --build -d
#   Logs:   docker compose -f docker-compose.gpu.yml logs -f
#   Stop:   docker compose -f docker-compose.gpu.yml down
#   Restart: docker compose -f docker-compose.gpu.yml restart
#
# Prerequisites:
#   1. NVIDIA Container Toolkit installed:
#        https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html
#   2. docker run --gpus all working on the host
#   3. Model files present at ./base_model_qwen7b (or path set below)
