It is unclear if this thread is the feeling of two TC members or enough TC members care deeply about this issue to permanently limit OpenStack big tent projects’ ability to generate container images in various external artifact storage systems.  The point of discussion I see effectively raised in this thread is “OpenStack infra will not push images to dockerhub”.
