30.3. Usage

This section describes how you can use the insert-header-action.

30.3.1. Knative Action

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

insert-header-action-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: insert-header-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: insert-header-action
    properties:
      name: "The Name"
      value: "The Value"
  sink:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel

30.3.1.1. Prerequisite

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

30.3.1.2. Procedure for using the cluster CLI

  1. Save the insert-header-action-binding.yaml file to your local drive, and then edit it as needed for your configuration.
  2. Run the action by using the following command:

    oc apply -f insert-header-action-binding.yaml

30.3.1.3. Procedure for using the Kamel CLI

Configure and run the action by using the following command:

kamel bind timer-source?message=Hello --step insert-header-action -p "step-0.name=The Name" -p "step-0.value=The Value" channel:mychannel

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

30.3.2. Kafka Action

You can use the insert-header-action Kamelet as an intermediate step in a Kafka binding.

insert-header-action-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: insert-header-action-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: timer-source
    properties:
      message: "Hello"
  steps:
  - ref:

      name: insert-header-action
    properties:
      name: "The Name"
      value: "The Value"
  sink:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic

30.3.2.1. Prerequisites

Ensure that you’ve installed the AMQ Streams operator in your OpenShift cluster and created a topic named my-topic in the current namespace. Make also sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.

30.3.2.2. Procedure for using the cluster CLI

  1. Save the insert-header-action-binding.yaml file to your local drive, and then edit it as needed for your configuration.
  2. Run the action by using the following command:

    oc apply -f insert-header-action-binding.yaml

30.3.2.3. Procedure for using the Kamel CLI

Configure and run the action by using the following command:

kamel bind timer-source?message=Hello --step insert-header-action -p "step-0.name=The Name" -p "step-0.value=The Value" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic

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