This script is a real pain to get correct. The problem is quite low priority so I'm going to set this aside for now. Worst case scenario these images will get auto upgraded.
Anping let me know if you have a good reproducer for getting a <none>:<none> orphaned image, I can't quite seem to do it.
oc new-app cakephp-example, this command will create 172.30.55.28:5000/test/django-example:<none>
I think this could be considered fixed now, however I can't fully guarantee nuke_images.sh will get everything, Docker has been quite fussy about what it will delete and sometimes just outright breaks. However the new changes arrived in: https://github.com/openshift/openshift-ansible/pull/2285 You can see all the details in there but I think the new method of clearing out images might be more reliable, and should get these none/none orphans. This should be built with openshift-ansible-3.3.10-1 so I will move to ON_QA.
Verified and pass, those images with <none> tag was removed.
