dockerhelper 0.0.6

This project was mainly created to automate the build, tag, and push process of docker via rake tasks and reuse these across multiple projects. It also provides tasks for generating Kubernetes replication controllers, creating them in Kubernetes, and running rolling-update on Kubernetes. I recognize the code is not high quality and I expect there are many bugs. Hell, there are no unit tests! Use with extreme caution! This gem is currently in active development with a high risk of breaking changes every release (hence a <1 version).
