In production, a Bento container is deployed, but we place it behind a proxy. In FastAPI, what I would do is edit the

root_path

in order for everything to work as expected, e.g.

app = FastAPI(
    root_path="/api/v1")

What I'm trying to achieve, is have this

root_path

defined by a environment variable, e.g.

root_path=os.environ["API_ROOT_PATH"]

. Since BentoML wraps FastAPI for me, I wonder how can I achieve that?
