CLI example: Create and manage a Windows pool in Azure Batch
This script demonstrates some of the commands available in the Azure CLI to create and manage a pool of Windows compute nodes in Azure Batch. A Windows pool can be configured in two ways, with either a Cloud Services configuration or a Virtual Machine configuration. This example shows how to create a Windows pool with the Cloud Services configuration.
Open Azure Cloud Shell
Azure Cloud Shell is a free, interactive shell that you can use to run the steps in this article. Common Azure tools are preinstalled and configured in Cloud Shell for you to use with your account. Select Copy to copy the code, paste it in Cloud Shell, and then press Enter to run it. There are a few ways to open Cloud Shell:
|Select Try It in the upper-right corner of a code block.|
|Open Cloud Shell in your browser.|
|Select the Cloud Shell button on the menu in the upper-right corner of the Azure portal.|
If you choose to install and use the CLI locally, this article requires that you are running the Azure CLI version 2.0.20 or later. Run
az --version to find the version. If you need to install or upgrade, see Install Azure CLI.

Clean up deployment
Run the following command to remove the resource group and all resources associated with it.
az group delete --name myResourceGroup
