71.3. Usage
This section describes how you can use the timestamp-router-action.
71.3.1. 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/v1alpha1
kind: KameletBinding
metadata:
name: 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: timestamp-router-action
sink:
ref:
kind: Channel
apiVersion: messaging.knative.dev/v1
name: mychannel
71.3.1.1. Prerequisite
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
71.3.1.2. Procedure for using the cluster CLI
-
Save the
timestamp-router-action-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the action by using the following command:
oc apply -f timestamp-router-action-binding.yaml
71.3.1.3. Procedure for using the Kamel CLI
Configure and run the action by using the following command:
kamel bind timer-source?message=Hello --step timestamp-router-action channel:mychannel
This command creates the KameletBinding in the current namespace on the cluster.
71.3.2. 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/v1alpha1
kind: KameletBinding
metadata:
name: 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: timestamp-router-action
sink:
ref:
kind: KafkaTopic
apiVersion: kafka.strimzi.io/v1beta1
name: my-topic
71.3.2.1. 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.
71.3.2.2. Procedure for using the cluster CLI
-
Save the
timestamp-router-action-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the action by using the following command:
oc apply -f timestamp-router-action-binding.yaml
71.3.2.3. Procedure for using the Kamel CLI
Configure and run the action by using the following command:
kamel bind timer-source?message=Hello --step timestamp-router-action kafka.strimzi.io/v1beta1:KafkaTopic:my-topic
This command creates the KameletBinding in the current namespace on the cluster.
