# 1. Use a lightweight Python version
FROM python:3.9-slim
# 2. Set the working directory inside the container
WORKDIR /app

# 3. Copy requirements and install them
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

# 4. Pre-download the Fashion-CLIP model during the build process
# (This prevents the app from timing out when it first starts up)
RUN python -c "from transformers import CLIPModel, CLIPProcessor; \
    model = CLIPModel.from_pretrained('patrickjohncyh/fashion-clip'); \
    processor = CLIPProcessor.from_pretrained('patrickjohncyh/fashion-clip'); \
    print('Fashion-CLIP model preloaded!')"

# 5. Copy the rest of the application code
COPY . .

# 6. Create a user to run the app (Security best practice for HF Spaces)
RUN useradd -m -u 1000 user
USER user
ENV HOME=/home/user \
    PATH=/home/user/.local/bin:$PATH

# 7. Start the application
CMD ["uvicorn", "app:app", "--host", "0.0.0.0", "--port", "7860"]
