CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"]
Key Rules
- System deps before pip: Install all apt packages before
pip install - Clean apt cache: Always end apt stanza with
&& rm -rf /var/lib/apt/lists/* - OSQP first:
osqpmust be in requirements.txt beforepyportfolioopt - Slim base: Use
python:3.X-slimfor smaller image size
Customization
- Adjust
CMDfor your framework (FastAPI/uvicorn shown above) - Add additional Python packages to requirements.txt after the core two
- For Gunicorn:
CMD ["gunicorn", "-w", "4", "-b", "0.0.0.0:8000", "main:app"]
