# This reverse proxy configuration aims to make calls to different services running under different ports (Streamlit :8501 and FastAPI :8000) by calling only one port : the nginx one (configurable via NGINX_PORT)
# The NGINX_PORT has to be opened (Dockerfile) and used by app.py (streamlit) in order to make right calls.
