= Filtering events using triggers
|
|
|
|
In the following trigger example, only events with the attribute `type: dev.knative.samples.helloworld` will reach the event sink.
|
|
|
|
[source,terminal]
|
|
----
|
|
$ kn trigger create <trigger_name> --broker <broker_name> --filter type=dev.knative.samples.helloworld --sink ksvc:<service_name>
|
|

|
|
You can also filter events using multiple attributes. The following example shows how to filter events using the type, source, and extension attributes.
|
|
|
|
[source,terminal]
|
|

|
$ 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
