Connect an event source to a sink using the Developer perspective

You can create multiple event source types in OpenShift Container Platform that can be connected to sinks.


To connect an event source to a sink using the Developer perspective, ensure that:

  • The OpenShift Serverless Operator, Knative Serving, and Knative Eventing are installed on your OpenShift Container Platform cluster.

  • You have created a sink.

  • You have logged in to the web console and are in the Developer perspective.

  • You have created a project or have access to a project with the appropriate roles and permissions to create applications and other workloads in OpenShift Container Platform.

  1. Create an event source of any type, by navigating to +AddEvent Sources and then selecting the event source type that you want to create.

  2. In the Sink section of the Event Sources form view, select Resource. Then use the drop-down list to select your sink.

  3. Click Create.


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

  1. In the Developer perspective, navigate to Topology.

  2. View the event source and click on the connected sink to see the sink details in the side panel.
