[treeder]

I assume #4 closes this?

[denismakogon]

yes.

It looks like it's not using the dev image to build. I guess python isn't doing the multi-stage builds yet?

[denismakogon]

Yeah, python doesn't do multi-stage builds yet.

[denismakogon]

So, what would be the short-term solution:

1. Let CLI use fnproject/python:3.6-dev?
2. Make Python run multi-stage builds?
3. Leave as is since we can override build image?

[treeder]

Ok, well easy fix is to change it to fnproject/python:3.6-dev.

Posted at the same time.

2 is best option if it can work with python.
