Introduction

pipenv-all is a docker image with as many python versions as possible installed with pipenv. This allows for quickly testing a python library against a wide variety of python versions without requiring the build agent to have them all installed. Pipenv allows for the toolchain to be locked and updated incrementally looking for breakages due to dependency updates, its similar to pip freeze but maintains SHAs protecting against modifications to the same version (which can be achieved in Pypi if a developer tries).
