Installing the Template Service Broker

You can install the Template Service Broker to gain access to the template applications that it provides.

The Template Service Broker is deprecated in OpenShift Container Platform 4. Equivalent and better functionality is present in the Operator Framework and Operator Lifecycle Manager (OLM).

By default, the Samples Operator handles Red Hat Enterprise Linux (RHEL)-based OpenShift Container Platform imagestreams and OpenShift Container Platform templates. See Configuring the Samples Operator for details.

About the Template Service Broker

The Template Service Broker gives Service Catalog visibility into the default Instant App and Quickstart templates that have shipped with OpenShift Container Platform since its initial release. The Template Service Broker 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 Template Service Broker shows objects that are globally available from the openshift project. It can also be configured to watch any other project that a cluster administrator chooses.

The Template Service Broker is not installed by default in OpenShift Container Platform 4.
