Thanks, I'll look into it.

300MB is the rounded size of the size reported by the dockerhub UI
e.g https://hub.docker.com/r/tripleopike/centos-binary-heat-api/
shows 265MB for the newest tag. I'm not sure what size is dockerhub

When pulling the image, docker downloads 30 layers. The final size
reported locally is 815MB.
