$ kn trigger create <trigger_name> --broker <broker_name> --filter type=dev.knative.samples.helloworld --sink ksvc:<service_name>
Using the Knative (kn
) CLI to filter events by using triggers provides a streamlined and intuitive user interface. You can use the kn trigger create
command, along with the appropriate flags, to filter events by using triggers.
In the following trigger example, only events with the attribute type: dev.knative.samples.helloworld
are sent to the event sink:
$ kn trigger create <trigger_name> --broker <broker_name> --filter type=dev.knative.samples.helloworld --sink ksvc:<service_name>
You can also filter events by using multiple attributes. The following example shows how to filter events using the type, source, and extension attributes:
$ kn trigger create <trigger_name> --broker <broker_name> --sink ksvc:<service_name> \
--filter type=dev.knative.samples.helloworld \
--filter source=dev.knative.samples/helloworldsource \
--filter myextension=my-extension-value
