| # Rune Goblin RPG sandbox — Hugging Face Docker Space. | |
| # | |
| # Runs app/rpg_app.py (the Gradio canvas RPG) under uvicorn. No model weights | |
| # ship: the drawn-rune vision model is OFF (RG_USE_MODEL=0 -> deterministic rule | |
| # engine reads glyphs) and NPC dialogue is a remote HTTP call to the Modal API | |
| # (RG_DIALOGUE_API_* set as Space secrets). Small, CPU-only image. | |
| FROM python:3.12-slim | |
| # git is needed by HF "Dev Mode": when enabled, HF appends build steps | |
| # (openvscode-server + `git config --global ...`) after our COPYs, and the slim | |
| # base ships no git -> the build fails with "git: not found". Install it as root | |
| # before dropping to the unprivileged user. Harmless when Dev Mode is off. | |
