# 1. Copy requirements first to leverage Docker caching
# If your requirements.txt is inside a 'backend' folder, change this to: COPY --chown=user backend/requirements.txt .
COPY --chown=user requirements.txt .
RUN pip install --no-cache-dir --upgrade -r requirements.txt

# 2. Copy the rest of the files
COPY --chown=user . .

# 3. Start the application
# If main.py is in the root of your Space, use:
# CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "7860"]
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "7860", "--workers", "2"]

# IF main.py is inside a 'backend' folder, use this instead:
# CMD ["uvicorn", "backend.main:app", "--host", "0.0.0.0", "--port", "7860"]
