Chapter 15. Azure Storage Blob Sink

Upload data to Azure Storage Blob.

Important

The Azure Storage Blob Sink Kamelet is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production.

These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information about the support scope of Red Hat Technology Preview features, see https://access.redhat.com/support/offerings/techpreview.

The Kamelet expects the following headers to be set:

  • file / ce-file: as the file name to upload

If the header won’t be set the exchange ID will be used as file name.

Copy link

This section describes how you can use the azure-storage-blob-sink.

15.3.1. Knative Sink
Copy link

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

azure-storage-blob-sink-binding.yaml

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

  2. Run the sink by using the following command: 

    oc apply -f azure-storage-blob-sink-binding.yaml
    Copy to Clipboard Toggle word wrap

15.3.1.3. Procedure for using the Kamel CLI
Copy link

Configure and run the sink by using the following command: 

kamel bind channel:mychannel azure-storage-blob-sink -p "sink.accessKey=The Access Key" -p "sink.accountName=The Account Name" -p "sink.containerName=The Container Name"
Copy to Clipboard Toggle word wrap

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

metadata:
  name: azure-storage-blob-sink-binding
spec:
  source:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic
  sink:
    ref:
