`pserve development.ini` gives traceback ImportError: No module named testsite

Question

I have a Pyramid project I am trying to migrate to Docker from VBox. When I attempt to startup the Gunicorn WSGI server with pserve development.ini

I get this traceback:

To replicate everything exactly, here is the Docker container (https://github.com/rajsinghUSA/testsite), which I build using this line:

docker build -t image_from_dockerfile -f testsite.Dockerfile .
