The API server source is an event source that can be used to connect an event sink, such as a Knative service, to the Kubernetes API server. The API server source watches for Kubernetes events and forwards them to the Knative Eventing broker.

Creating an API server source by using the web console

After Knative Eventing is installed on your cluster, you can create an API server source by using the web console. Using the OpenShift Container Platform web console provides a streamlined and intuitive user interface to create an event source.

Prerequisites
  • You have logged in to the OpenShift Container Platform web console.

  • The OpenShift Serverless Operator and Knative Eventing are installed on the cluster.

  • 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.

  • You have installed the OpenShift (oc) CLI.

Procedure
  1. Navigate to the Add page and select Event Source.

  2. In the Event Sources page, select ApiServerSource in the Type section.

  3. Configure the ApiServerSource settings:

    1. Enter v1 as the APIVERSION, and Event as the KIND.

    2. Select the Service Account Name for the service account that you created.

    3. Select the Sink for the event source. A Sink can be either a Resource, such as a channel, broker, or service, or a URI.

  4. Click Create.

Verification
  • After you have created the API server source, you will see it connected to the service it is sinked to in the Topology view.
