Custom Builder Pull Error



Good Morning,


I'm playing around with the openshift dev preview, in doing so I'm toying around with creating a custom s2i builder specifically for the phoenix web framework.  While it's not feature complete, I've had a working example up until today.  After updating the builder image, I'm struggling to figure out why openshift can't pull it down to complete a build.  I've published my custom builder in the public on dockerhub.


After importing the image stream and providing the builder my source code, initiating a build will fail.  Here's the log output

Unfortunately, openshift doesn't say WHY it was unable to get the image.  This did previously work until I updated the image.  The only thing at this point I can think of, is that I recently built the image on version 1.12 of docker.  But I'm kinda brushing that off, cuz I've seen openshift complain in the past about manifest versions; and secondly when I started this project, I was using docker 1.12 beta...
