Excellent! As seen from your 2nd link, Streamlit is so versatile, that it does not even require shipping a custom config file inside the container. You can do it with an env var (STREAMLIT_SERVER_HEADLESS=true) or a parameter passed to the server (streamlit run your_app.py --server.headless true). – Explicate
