Hi @rjhenry, thanks for creating this PR,

Instead of adding a hardcoded environment variable in the Ansible's playbook, I would rather prefer to have a new Ansible var pip_environment_var containing a list of environment variables that need to be passed to pip command execution.

Could you please update the PR so that generic variable can be used?

Thanks
Regards
Ricardo

I went with minio_pip_environment_vars, mostly to indicate the scope of the variable in it's name.

Looks like those Molecule tests are a) only warnings and b) also happening on master now. I suspect something's updated somewhere or similar?

Currently there is an issue, ansible-collections/community.docker#860, making ansible docker package not workig and so "molecule" workflows are broken. There is a molecule, PR ansible/molecule#4185 fixes this issue, so I won`t apply workarround in github actions to avoid installation of the broken package.
