Create an Azure Compute Fleet using an ARM template (Preview)
Important
Azure Compute Fleet is currently in preview. Previews are made available to you on the condition that you agree to the supplemental terms of use. Some aspects of this feature may change prior to general availability (GA).
This article steps through using an ARM template to create an Azure Compute Fleet.
An Azure Resource Manager template is a JavaScript Object Notation (JSON) file that defines the infrastructure and configuration for your project. The template uses declarative syntax. You describe your intended deployment without writing the sequence of programming commands to create the deployment.
Prerequisites
- If you don't have an Azure subscription, create a free account before you begin.
- Before using Compute Fleet, complete the feature registration and configure role-based access controls (RBAC).
Feature registration
Register the Azure Compute Fleet resource provider with your subscription using PowerShell or Azure portal. Registration can take up to 30 minutes to successfully show as registered.
Register-AzResourceProvider -ProviderNamespace Microsoft.AzureFleet
Role-based access control permissions
Assign the appropriate RBAC permissions to use Azure Compute Fleet.
- In the Azure portal, navigate to your subscriptions.
- Select the subscription you want to adjust RBAC permissions.
- Select Access Control (IAM).
- Select Add, then Add Role Assignment.
- Search for Virtual Machine Contributor and highlight it. Select Next.
- Click on + Select Members.
- Search for Azure Fleet Resource Provider role.
- Select the Azure Fleet Resource Provider and select Review + Assign.
- Repeat the previous steps for the Network Contributor role and the Managed Identity Operator role.
If you're using images stored in Compute Gallery when deploying your Compute Fleet, also repeat the previous steps for the Compute Gallery Sharing Admin role.
For more information on assigning roles, see assign Azure roles using the Azure portal.
ARM template
An Azure Resource Manager template is a JavaScript Object Notation (JSON) file that defines the infrastructure and configuration for your project. The template uses declarative syntax. You describe your intended deployment without writing the sequence of programming commands to create the deployment.
ARM templates let you deploy groups of related resources. In a single template, you can create the Virtual Machine Scale Set, install applications, and configure autoscale rules. With the use of variables and parameters, this template can be reused to update existing, or create extra scale sets. You can deploy templates through the Azure portal, Azure CLI, or Azure PowerShell, or from continuous integration / continuous delivery (CI/CD) pipelines.

These resources are defined in the template:
Clean up resources
When no longer needed, you can use az group delete to remove the resource group, scale set, and all related resources as follows. The --no-wait parameter returns control to the prompt without waiting for the operation to complete. The --yes parameter confirms that you wish to delete the resources without another prompt to do so.
az group delete --name myResourceGroup --yes --no-wait
