Looks like this was an issue with using Runway inside of CI/CD systems that didn't attach a terminal - Runway runs stacker in interactive mode, and so without a terminal there was no way to approve the changes.

(This was figured out by folks in the stacker slack channel: https://empirepaas.slack.com/archives/C08NMGJSH/p1544003933000500)

Closing!
