Dependencies

At runtime, the timestamp-router-action Kamelet relies upon the presence of the following dependencies:

  • mvn:org.apache.camel.kamelets:camel-kamelets-utils:4.0.4-SNAPSHOT

  • camel:kamelet

  • camel:core

Camel JBang usage

Prerequisites

  • You’ve installed JBang.

  • You have executed the following command:

jbang app install camel@apache/camel

Supposing you have a file named route.yaml with this content:

- route:
    from:
      uri: "kamelet:timer-source"
      parameters:
        period: 10000
        message: 'test'
      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command

camel run route.yaml

Camel K Environment Usage

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

Knative action

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

timestamp-router-action-binding.yaml
apiVersion: camel.apache.org/v1
kind: KameletBinding
metadata:
  name: timestamp-router-action-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: kafka-source
      properties:
        bootstrapServers: localhost:9092
        topic: mytopic
        user: kafka
        password: kafka123!
  steps:
    - ref:
        kind: Kamelet
        apiVersion: camel.apache.org/v1
        name: timestamp-router-action
  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 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 timestamp-router-action-binding.yaml

Procedure for using the Kamel CLI

Configure and run the action by using the following command:

kamel bind channel:mychannel  timestamp-router-action

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

Kafka action

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

timestamp-router-action-binding.yaml
apiVersion: camel.apache.org/v1
kind: KameletBinding
metadata:
  name: timestamp-router-action-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: kafka-source
      properties:
        bootstrapServers: localhost:9092
        topic: mytopic
        user: kafka
        password: kafka123!
  steps:
    - ref:
        kind: Kamelet
        apiVersion: camel.apache.org/v1
        name: timestamp-router-action
  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 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 timestamp-router-action-binding.yaml

Procedure for using the Kamel CLI

Configure and run the action by using the following command:

kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic  timestamp-router-action

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