Docker compare history

NAME:

   docker-history-compare - Docker image history compare

Why did we built it

For some of our clients we are using 3rd party services like CircleCI, CodeShip. These services has a caching mecanisem that allows us to save a Docker image and next build to load it from cache to Docker. We needed a tool to tell us if layers the in the image changed and only then to save it to cache. This saved us ~20 sec for every build since we didn't had to save to cache already exsits images.
