32.3. Usage

This section describes how you can use the json-serialize-action.

32.3.1. Knative Action

You can use the json-serialize-action Kamelet as an intermediate step in a Knative binding.

json-serialize-action-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: json-serialize-action-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: timer-source
    properties:
      message: "Hello"
  steps:
  - ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: json-serialize-action
  sink:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel

32.3.1.1. Prerequisite

Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.

32.3.1.2. Procedure for using the cluster CLI

Save the json-serialize-action-binding.yaml file to your local drive, and then edit it as needed for your configuration.

Run the action by using the following command:

oc apply -f json-serialize-action-binding.yaml

32.3.1.3. Procedure for using the Kamel CLI

Configure and run the action by using the following command:

kamel bind timer-source?message=Hello --step json-serialize-action channel:mychannel

This command creates the KameletBinding in the current namespace on the cluster.
