Export cluster ARM template - Azure portal

  • Artikkeli

Note

We will retire Azure HDInsight on AKS on January 31, 2025. Before January 31, 2025, you will need to migrate your workloads to Microsoft Fabric or an equivalent Azure product to avoid abrupt termination of your workloads. The remaining clusters on your subscription will be stopped and removed from the host.

Only basic support will be available until the retirement date.

This article describes how to generate an ARM template for your cluster automatically. You can use the ARM template to modify, clone, or recreate a cluster starting from the existing cluster's configurations.

Prerequisites

  • An operational HDInsight on AKS cluster.

Steps to generate ARM template for the cluster

  1. Sign in to Azure portal.

  2. In the Azure portal search bar, type "HDInsight on AKS cluster" and select "Azure HDInsight on AKS clusters" from the drop-down list.

  4. Navigate to the "Export template" blade of your cluster and click "Download" to export the template.

Now, your cluster ARM template is ready. You can update the properties of the cluster and finally deploy the ARM template to refresh the resources. To redeploy, you can either use the "Deploy" option in your cluster under "Export template" blade by replacing the existing template with the modified template or see deploy an ARM template using Azure portal.

Important

If you're cloning the cluster or creating a new cluster, you'll need to modify the name, location, and fqdn (the fqdn must match the cluster name).
