6.3.2. DNS Information

The sample deployment steps configure a DNS service to allow OpenShift Enterprise to dynamically publish DNS host names of applications within your chosen domain. This can only be made authoritative by an external authority, such as your system administrator, or Internet service provider. If the OpenShift Enterprise name server is not made authoritative by your DNS provider, application host names are visible only on the OpenShift Enterprise hosts, or any workstation configured to use the same DNS service. Alternatively, OpenShift Enterprise can publish to an existing authoritative service if given the necessary credentials for the domain.

The process of creating an authoritative DNS service and establishing a delegation agreement with your IT department are beyond the scope of this guide. Each organization has its own policies and procedures for managing DNS services. The requirements must be discussed with the appropriate personnel for your site to make the OpenShift Enterprise service available.
