If you need a guideline about how to build TripleO images with DIB, i have
that blogpost:
http://teknoarticles.blogspot.com.es/2017/07/build-and-use-security-hardened-images.html

This if for security hardened images, but your replace
"overcloud-hardened-images" by "overcloud-images", it will build the
default one. You can specify the base image you want to use, as well as
enable any repo you have, that may take the latest kernel.

Hope it helps!
