instack-build-images building RHEL7 subscribed images will not pass outside of Red Hat VPN because it depends on virt.bos.redhat.com URL for rhos-release repo. Problem is in this part: * https://github.com/rdo-management/instack-undercloud/blob/master/scripts/instack-build-images#L97 * https://github.com/rdo-management/instack-undercloud/blob/master/elements/rhos-release/pre-install.d/00-rhos-release#L10 This is hard dependency on the URL. This repo should be available from subscription-manager and rhel-7-server-openstack-6.0-rpms enabled repo. Some variable which can be overwritten should work.
This hard requirement on rhos-release should be addressed by the changes in: https://review.gerrithub.io/#/c/227955. The commit above should enable (and document) the option of using Subscription Manager for rdo-manager install and overcloud deploy.
