| # 3. Install System Dependencies | |
| # - ffmpeg: for video processing | |
| # - git: in case any pip package needs to be installed from a git source | |
| RUN apt-get update && \ | |
| apt-get install -y --no-install-recommends \ | |
| ffmpeg \ | |
| git \ | |
| curl \ | |
| && apt-get clean && \ | |

| # 4. Set Working Directory | |
| WORKDIR /app | |
| # 5. Copy requirements.txt and Install Python Dependencies | |
| COPY requirements.txt . | |
| RUN pip install --no-cache-dir -r requirements.txt | |
| # 6. Copy Application Code and Secrets | |
| # First, copy the secrets file (if it exists and you intend to build it into the image) | |
| # WARNING: Building secrets into the image is generally NOT recommended for production. | |
| # Manage secrets via environment variables or Docker secrets/volume mounts at runtime. | |
| # This is included for completeness if you are managing it this way for development. | |
| COPY .streamlit/secrets.toml .streamlit/secrets.toml | |
| # Copy the rest of your application code | |
| COPY app.py . | |
| # If you have other Python modules or asset files, copy them as well: | |
| # COPY your_module.py . | |
| # COPY assets/ /app/assets/ | |
| # 7. Create Hugging Face cache directory and set permissions (optional) | |
| # This helps if the user running the container is not root and needs to write to cache. | |
| RUN mkdir -p /app/.huggingface_cache && \ | |
| chmod -R 777 /app/.huggingface_cache | |
| # 8. Expose Port for Streamlit | |
| EXPOSE 8501 | |
| # 9. Healthcheck (Optional but recommended) | |
| HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 \ | |
| CMD curl --fail http://localhost:8501/_stcore/health || exit 1 | |
| # 10. Command to Run the Streamlit Application | |
| # The --server.address=0.0.0.0 makes the app accessible externally from the container. | |
| CMD ["streamlit", "run", "app.py", "--server.port=8501", "--server.address=0.0.0.0", "--logger.level=info"] |
