The template service broker (TSB) gives the service catalog visibility into the default Instant App and Quickstart templates that have shipped with OpenShift Container Platform since its initial release. The TSB can also make available as a service anything for which an OpenShift Container Platform template has been written, whether provided by Red Hat, a cluster administrator or user, or a third party vendor.

By default, the TSB shows the objects that are globally available from the openshift project. It can also be configured to watch any other project that a cluster administrator chooses.
