Functions are deployed as a Knative service on a OpenShift Container Platform cluster, and can be connected as a sink to Knative Eventing components.
When you create an event source by using the OpenShift Container Platform web console, you can specify a sink where events are sent to from that resource. The sink can be any addressable or callable resource that can receive incoming events from other resources.
The OpenShift Serverless Operator, Knative Serving, and Knative Eventing are installed on your OpenShift Container Platform cluster.

You can verify that the event source was created and is connected to the sink by viewing the Topology page.
