5.8. Updating triggers from the command line

Prerequisites

• The OpenShift Serverless Operator and Knative Eventing are installed on your OpenShift Container Platform cluster.
• You have installed the Knative (kn) CLI.
• 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.

Procedure

• Update a trigger:

  $ kn trigger update <trigger_name> --filter <key=value> --sink <sink_name> [flags]

  • You can update a trigger to filter exact event attributes that match incoming events. For example, using the type attribute:

    $ kn trigger update <trigger_name> --filter type=knative.dev.event

  • You can remove a filter attribute from a trigger. For example, you can remove the filter attribute with key type:

    $ kn trigger update <trigger_name> --filter type-

  • You can use the --sink parameter to change the event sink of a trigger:

    $ kn trigger update <trigger_name> --sink ksvc:my-event-sink
