Usage

This section describes how you can use the message-timestamp-router-action.

Knative Action

You can use the message-timestamp-router-action Kamelet as an intermediate step in a Knative binding.

message-timestamp-router-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: message-timestamp-router-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: message-timestamp-router-action
    properties:
      timestampKeys: "The Timestamp Keys"
  sink:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel

Prerequisite

You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the message-timestamp-router-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:

    kubectl apply -f message-timestamp-router-action-binding.yaml

Procedure for using the Kamel CLI

Configure and run the action by using the following command:

kamel bind timer-source?message=Hello --step message-timestamp-router-action -p "step-0.timestampKeys=The Timestamp Keys" channel:mychannel

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

Kafka Action

You can use the message-timestamp-router-action Kamelet as an intermediate step in a Kafka binding.

message-timestamp-router-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: message-timestamp-router-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: message-timestamp-router-action
    properties:
      timestampKeys: "The Timestamp Keys"
  sink:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic

Prerequisites

  • You’ve installed Strimzi.

  • You’ve created a topic named my-topic in the current namespace.

  • You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the message-timestamp-router-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:

    kubectl apply -f message-timestamp-router-action-binding.yaml

Procedure for using the Kamel CLI

Configure and run the action by using the following command:

kamel bind timer-source?message=Hello --step message-timestamp-router-action -p "step-0.timestampKeys=The Timestamp Keys" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic

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