# 1. Use an official lightweight Python base image
FROM python:3.11-slim

# 2. Set the working directory inside the container
WORKDIR /app

# 3. Install system dependencies
# This is required by opencv-python-headless (a dependency of rembg)
RUN apt-get update && apt-get install -y \
    libgl1 \
    && rm -rf /var/lib/apt/lists/*

# 4. Copy requirements file first to leverage Docker layer caching
COPY requirements.txt .

# 5. Install Python dependencies
# --no-cache-dir keeps the image size smaller
RUN pip install --no-cache-dir --upgrade pip && \
    pip install --no-cache-dir -r requirements.txt



# 7. Copy your application code into the container
COPY main.py .

# 8. Expose the port your app runs on
# Hugging Face Spaces automatically uses port 7860
EXPOSE 7860

# 9. The command to run your FastAPI server
CMD ["python", "-m", "uvicorn", "main:app", "--host", "0.0.0.0", "--port", "7860"]
