GitHub Actions - Python with Custom Package Index

Aim: build python code that pulls packages from a custom pypy (Python Package Index). And pushes own packages to that private index.

Add to git repo

In the git repo, add the following:

1. Add the file, pip.config, that contains the URLs to the private pypi index to pull packages from.
2. Add the file, .pypirc, that contains credentials to the private pypi index where you want to push your packages to.

GH-Actions Workflow yml

In the GitHub Actions workflow, do the following:

1. Add the environment variable PIP_CONFIG_FILE that points to a pip.config file.
2. When pushing the python package, pass the path of .pypirc to twine to upload the package.
