Harbinger is a docker orchestration made in python. The goal of Harbinger is to give an easy-to-use and friendly interface to it's users. Sometimes using docker can end up being a huge bottleneck in your workflow, but maybe not with Harbinger.

As of right now, very few of Harbinger's promised capabilities are merely a thought or idea. Although, it will not be this way for very long.

None of this would be possible without docker, I've just found that docker's cli is not very good and it's even worse with multiple images/containers.
