Description

Trying to use build-arg options for a build, it seems there is no way to supply build-args to either the first nor second docker build runs.

This is useful to bake an image with some configuration. I was trying to use {{build-arg}}s to ensure a Docker and Vagrant run could share configuration via shell environment variables.
