   PingSource        pingsources.sources.knative.dev                 Periodically send ping events to a sink
   SinkBinding       sinkbindings.sources.knative.dev                Binding for connecting a PodSpecable to a sink

2. Optional: On OpenShift Container Platform, you can also list the available event source types in YAML format:

   a1     ApiServerSource   apiserversources.sources.knative.dev   ksvc:eshow2   True
   b1     SinkBinding       sinkbindings.sources.knative.dev       ksvc:eshow3   False
   p1     PingSource        pingsources.sources.knative.dev        ksvc:eshow1   True

2. Optional: You can list event sources of a specific type only, by using the --type flag:

   $ kn source list --type <event_source_type>
