Dockerfile for azure functions python using fastapi and poetry

I was able to get an azure function app with fastapi running using the example here: https://github.com/Azure-Samples/fastapi-on-azure-functions

I want to containerize my app. I also want able to acheive it using the sample generated by VS code. It uses the azure functions python base image and pip.

Here's my current hurdle. I prefer to use poetry over pip. I can't figure out how to containerize the app with poetry instead of pip. Do you have a sample of a Dockerfile for my scenario?
