This is a RFE to provide an example topology and deployment in the Installation and Configuration Guide located at http://documentation-devel.engineering.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/4-Beta/html/Installation_and_Configuration_Guide/Configuring_the_Installer.html this would help when users get to section 3.3 (Configuring the Installer) in that they would understand what PRIVATE_CONTROLLER_IP, PRIVATE_INTERFACE, etc would relate to within their deployment.
There used to be a section explaining the topology in the RHOS 3 docs, but I can't find it in the 4 docs. http://documentation-devel.engineering.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/3/html-single/Deployment_Guide_Foreman_Technology_Preview/index.html#sect-Requirements
Updating priority to match severity.
