# tts-server containerizzato (Qwen3-TTS, backend Vulkan)
# ----------------------------------------------------------------------------
# GPU supportate:
#   - AMD/Intel: Mesa RADV via /dev/dri/renderD128 (nessun driver nel container)
#   - NVIDIA:    ICD Vulkan (nvidia-container-toolkit) o /dev/dri
# Il driver kernel resta sull'host; il container monta solo il device node.
#
# Build:  docker build -t qwentts-tts:vulkan .
# Run:    docker compose up -d   (vedi docker-compose.yml)
