Chapter 7. Invoking functions


You can test a deployed function by invoking it. You can do it using the kn func tool.

7.1. Invoking a deployed function with a test event

You can use the kn func invoke CLI command to send a test request to invoke a function either locally or on your OpenShift Container Platform cluster. You can use this command to test that a function is working and able to receive events correctly. Invoking a function locally is useful for a quick test during function development. Invoking a function on the cluster is useful for testing that is closer to the production environment.

Prerequisites

  • The OpenShift Serverless Operator and Knative Serving are installed on the 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.
  • You must have already deployed the function that you want to invoke.

Procedure

  • Invoke a function:

    $ kn func invoke
    • The kn func invoke command only works when there is either a local container image currently running, or when there is a function deployed in the cluster.
    • The kn func invoke command executes on the local directory by default, and assumes that this directory is a function project.
