Functions are deployed as Knative services on an OpenShift Container Platform cluster. When you create an event source by using the OpenShift Container Platform web console, you can specify a deployed function that events are sent to from that source.
Prerequisites
- The OpenShift Serverless Operator, Knative Serving, and Knative Eventing are installed on your OpenShift Container Platform cluster.
- You have logged in to the web console.
- 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 created and deployed a function.
Procedure
-
Create an event source of any type, by navigating to +Add
Event Source and selecting the event source type that you want to create. - In the Target section of the Create Event Source form view, select your function in the Resource list.
- Click Create.
Verification
You can verify that the event source was created and is connected to the function by viewing the Topology page.
- Navigate to Topology.
- View the event source and click the connected function to see the function details in the right panel.
