# Make port 8000 available to the world outside this container
# Hugging Face Spaces typically expect the app on port 7860, but FastAPI defaults to 8000.
# We'll run on 8000 and let HF handle mapping if needed, or adjust the CMD.
# Let's use 7860 directly as it's common for HF.
EXPOSE 7860

# Define environment variables (optional, can be set in Hugging Face secrets)
# ENV GOOGLE_API_KEY="your_key_here" # It's better to use HF Secrets
# ENV PEXELS_API_KEY="your_key_here" # It's better to use HF Secrets

# Run main.py when the container launches
# Use 0.0.0.0 to make it accessible from outside the container.
# Use port 7860 as often expected by Hugging Face Spaces.
