[mcallaghan-bsm]

'twas using your alpine3 base image, and ran a few pip upgrades myself to get "latest-latest" going on an internal docker image

But yikes:

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

Looks like over the next 6 months or so need to flip over to python3 entirely!
