Lookcing at your dockerfile

node_modules/@serverless-stack/core/assets/python/Dockerfile.dependencies

I added the extra parameters

-r requirements.txt -t .

and the bundling worked as expected then

I didn't test how to use an extra-index-url for

pipenv

or

poetry

Those might need extra handling / testing. Potentially, some way to ma p in an extra pip.conf file might perhaps be an alternative to consider

The Python bundling options is very very basic at the moment. as none of us on team have in-depth python knowledge 😅

Most of what’s there are adopted from CDK’s python function and suggested by the community.
