using the value from docker images is not reliable. That sha256 changes
using .Config.Image from docker inspect appears to be a lot more reliable
- an image built on a centos7 w/ docker 1.8 and pulled to OSX docker beta ver 1.11 has the same value
- seems to be bit more reliable and better than the docker images route
