18.3. Usage

This section describes how you can use the azure-storage-queue-source.

18.3.1. Knative Source

You can use the azure-storage-queue-source Kamelet as a Knative source by binding it to a Knative object.

azure-storage-queue-source-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: azure-storage-queue-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: azure-storage-queue-source
    properties:
      accessKey: "The Access Key"
      accountName: "The Account Name"
      queueName: "The Queue Name"
  sink:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel

18.3.1.1. Prerequisite

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

18.3.1.2. Procedure for using the cluster CLI

Save the azure-storage-queue-source-binding.yaml file to your local drive, and then edit it as needed for your configuration.

Run the source by using the following command:

oc apply -f azure-storage-queue-source-binding.yaml

18.3.1.3. Procedure for using the Kamel CLI

Configure and run the source by using the following command:

kamel bind azure-storage-queue-source -p "source.accessKey=The Access Key" -p "source.accountName=The Account Name" -p "source.queueName=The Queue Name" channel:mychannel

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

18.3.2. Kafka Source

You can use the azure-storage-queue-source Kamelet as a Kafka source by binding it to a Kafka topic.

azure-storage-queue-source-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: azure-storage-queue-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: azure-storage-queue-source
    properties:
      accessKey: "The Access Key"
      accountName: "The Account Name"
      queueName: "The Queue Name"
  sink:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic

18.3.2.1. 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.

18.3.2.2. Procedure for using the cluster CLI

Save the azure-storage-queue-source-binding.yaml file to your local drive, and then edit it as needed for your configuration.

Run the source by using the following command:

oc apply -f azure-storage-queue-source-binding.yaml

18.3.2.3. Procedure for using the Kamel CLI

Configure and run the source by using the following command:

kamel bind azure-storage-queue-source -p "source.accessKey=The Access Key" -p "source.accountName=The Account Name" -p "source.queueName=The Queue Name" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic

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