Dependencies

At runtime, the azure-eventhubs-source Kamelet relies upon the presence of the following dependencies:

  • camel:azure-eventhubs

  • camel:kamelet

  • camel:jackson

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 azure-eventhubs-source.

Knative source

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

azure-eventhubs-source-pipe.yaml
apiVersion: camel.apache.org/v1
kind: Pipe
metadata:
  name: azure-eventhubs-source-pipe
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: azure-eventhubs-source
    properties:
      blobAccessKey: The Azure Storage Blob Access Key
      blobAccountName: The Azure Storage Blob Account Name
      blobContainerName: The Azure Storage Blob Container Name
      eventhubName: The Eventhubs Name
      namespaceName: The Eventhubs Namespace
  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 azure-eventhubs-source-pipe.yaml file to your local drive, and then edit it as needed for your configuration.

  2. Run the source by using the following command:

    kubectl apply -f azure-eventhubs-source-pipe.yaml

Procedure for using the Kamel CLI

Configure and run the source by using the following command:

kamel bind channel:mychannel -p "source.blobAccessKey=The Azure Storage Blob Access Key" -p "source.blobAccountName=The Azure Storage Blob Account Name" -p "source.blobContainerName=The Azure Storage Blob Container Name" -p "source.eventhubName=The Eventhubs Name" -p "source.namespaceName=The Eventhubs Namespace" azure-eventhubs-source

This command creates the Kamelet Pipe in the current namespace on the cluster.

Kafka source

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

azure-eventhubs-source-pipe.yaml
apiVersion: camel.apache.org/v1
kind: Pipe
metadata:
  name: azure-eventhubs-source-pipe
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: azure-eventhubs-source
    properties:
      blobAccessKey: The Azure Storage Blob Access Key
      blobAccountName: The Azure Storage Blob Account Name
      blobContainerName: The Azure Storage Blob Container Name
      eventhubName: The Eventhubs Name
      namespaceName: The Eventhubs Namespace
  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 azure-eventhubs-source-pipe.yaml file to your local drive, and then edit it as needed for your configuration.

  2. Run the source by using the following command:

    kubectl apply -f azure-eventhubs-source-pipe.yaml

Procedure for using the Kamel CLI

Configure and run the source by using the following command:

kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic -p "source.blobAccessKey=The Azure Storage Blob Access Key" -p "source.blobAccountName=The Azure Storage Blob Account Name" -p "source.blobContainerName=The Azure Storage Blob Container Name" -p "source.eventhubName=The Eventhubs Name" -p "source.namespaceName=The Eventhubs Namespace" azure-eventhubs-source

This command creates the Kamelet Pipe in the current namespace on the cluster.
