Create an Azure Compute Fleet using an ARM template

This article steps through using an ARM template to create an Azure Compute Fleet.

[!INCLUDE About Azure Resource Manager]

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.

PowerShell

Register-AzResourceProvider -ProviderNamespace Microsoft.AzureFleet

Azure portal

  1. In the Azure portal, navigate to your subscriptions.
  2. Select the subscription you want to enable Azure Compute Fleet on.
  3. Under Settings, select Resource providers.
  4. Search for Microsoft.AzureFleet and register the provider.

Role-based access control permissions

Assign the appropriate RBAC permissions to use Azure Compute Fleet.

  1. In the Azure portal, navigate to your subscriptions.
  2. Select the subscription you want to adjust RBAC permissions.
  3. Select Access Control (IAM).
  4. Select Add, then Add Role Assignment.
  5. Search for Virtual Machine Contributor and highlight it. Select Next.
  6. Click on + Select Members.
  7. Search for Azure Fleet Resource Provider role.
  8. Select the Azure Fleet Resource Provider and select Review + Assign.
  9. 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

[!INCLUDE About Azure Resource Manager]

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.

Review the template

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
