Chapter 16. Azure Storage Blob Source Consume Files from Azure Storage Blob. Important The Azure Storage Blob Source 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 . 16.1. Configuration Options The following table summarizes the configuration options available for the azure-storage-blob-source Kamelet: Property Name Description Type Default Example accessKey * Access Key The Azure Storage Blob access Key. string accountName * Account Name The Azure Storage Blob account name. string containerName * Container Name The Azure Storage Blob container name. string period * Period Between Polls The interval between fetches to the Azure Storage Container in milliseconds integer 10000 credentialType Credential Type Determines the credential strategy to adopt. Possible values are SHARED_ACCOUNT_KEY, SHARED_KEY_CREDENTIAL and AZURE_IDENTITY string "SHARED_ACCOUNT_KEY" Note Fields marked with an asterisk (*) are mandatory. 16.2. Dependencies At runtime, the azure-storage-blob-source Kamelet relies upon the presence of the following dependencies: camel:azure-storage-blob camel:jsonpath camel:core camel:timer camel:kamelet 16.3. Usage This section describes how you can use the azure-storage-blob-source . 16.3.1. Knative Source You can use the azure-storage-blob-source Kamelet as a Knative source by binding it to a Knative object. azure-storage-blob-source-binding.yaml apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: azure-storage-blob-source-binding spec: source: ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: azure-storage-blob-source properties: accessKey: "The Access Key" accountName: "The Account Name" containerName: "The Container Name" sink: ref: kind: Channel apiVersion: messaging.knative.dev/v1 name: mychannel 16.3.1.1. Prerequisite Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you're connected to. 16.3.1.2. Procedure for using the cluster CLI Save the azure-storage-blob-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-blob-source-binding.yaml 16.3.1.3. Procedure for using the Kamel CLI Configure and run the source by using the following command: kamel bind azure-storage-blob-source -p "source.accessKey=The Access Key" -p "source.accountName=The Account Name" -p "source.containerName=The Container Name" channel:mychannel This command creates the KameletBinding in the current namespace on the cluster. 16.3.2. Kafka Source You can use the azure-storage-blob-source Kamelet as a Kafka source by binding it to a Kafka topic. azure-storage-blob-source-binding.yaml apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: azure-storage-blob-source-binding spec: source: ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: azure-storage-blob-source properties: accessKey: "The Access Key" accountName: "The Account Name" containerName: "The Container Name" sink: ref: kind: KafkaTopic apiVersion: kafka.strimzi.io/v1beta1 name: my-topic 16.3.2.1. 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. 16.3.2.2. Procedure for using the cluster CLI Save the azure-storage-blob-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-blob-source-binding.yaml 16.3.2.3. Procedure for using the Kamel CLI Configure and run the source by using the following command: kamel bind azure-storage-blob-source -p "source.accessKey=The Access Key" -p "source.accountName=The Account Name" -p "source.containerName=The Container Name" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic This command creates the KameletBinding in the current namespace on the cluster. 16.4.
