CLI example: Create a Batch account in user subscription mode

This script creates an Azure Batch account in user subscription mode. An account that allocates compute nodes into your subscription must be authenticated via a Microsoft Entra token. The compute nodes allocated count toward your subscription's vCPU (core) quota.

If you don't have an Azure subscription, create an Azure free account before you begin.

Prerequisites

• Use the Bash environment in Azure Cloud Shell. For more information, see Quickstart for Bash in Azure Cloud Shell.

  

• If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.

  • If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.

  • When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.

  • Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.

Sample script

Launch Azure Cloud Shell

The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com.

When Cloud Shell opens, verify that Bash is selected for your environment. Subsequent sessions will use Azure CLI in a Bash environment, Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press Enter to run it.

Sign in to Azure

Cloud Shell is automatically authenticated under the initial account signed-in with. Use the following script to sign in using a different subscription, replacing subscriptionId with your Azure subscription ID.

If you don't have an Azure subscription, create an Azure free account before you begin.

subscription="subscriptionId" # Set Azure subscription ID here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in interactively.

Run the script

# Create a Batch account in user subscription mode

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
[[ "$RESOURCE_GROUP" == '' ]] && resourceGroup="msdocs-batch-rg-$randomIdentifier" || resourceGroup="${RESOURCE_GROUP}"
tag="create-account-user-subscription"
keyVault="msdocskeyvault$randomIdentifier"
batchAccount="msdocsbatch$randomIdentifier"

# Allow Azure Batch to access the subscription (one-time operation).
az role assignment create --assignee ddbf3205-c6bd-46ae-8127-60eb93363864 --role contributor

# Create a resource group
echo "Creating $resourceGroup in "$location"..."
az group create --name $resourceGroup --location "$location" --tag $tag

# Create an Azure Key Vault. A Batch account that allocates pools in the user's subscription 
# must be configured with a Key Vault located in the same region.
echo "Creating $keyVault" 
az keyvault create --resource-group $resourceGroup --name $keyVault --location "$location" --enabled-for-deployment true --enabled-for-disk-encryption true --enabled-for-template-deployment true

# Add an access policy to the Key Vault to allow access by the Batch Service.
az keyvault set-policy --resource-group $resourceGroup --name $keyVault --spn ddbf3205-c6bd-46ae-8127-60eb93363864 --key-permissions all --secret-permissions all

# Create the Batch account, referencing the Key Vault either by name (if they
# exist in the same resource group) or by its full resource ID.
echo "Creating $batchAccount"
az batch account create --resource-group $resourceGroup --name $batchAccount --location "$location" --keyvault $keyVault 

# Authenticate directly against the account for further CLI interaction.
# Batch accounts that allocate pools in the user's subscription must be
# authenticated via an Azure Active Directory token.
az batch account login -g $resourceGroup -n $batchAccount

Clean up resources

Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.

az group delete --name $resourceGroup
