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 an Azure Active Directory token. The compute nodes allocated count toward your subscription's vCPU (core) quota.

Use Azure Cloud Shell

Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. Cloud Shell lets you use either bash or PowerShell to work with Azure services. You can use the Cloud Shell pre-installed commands to run the code in this article without having to install anything on your local environment.

To launch Azure Cloud Shell:

Option Example/Link
Select Try It in the upper-right corner of a code block. Selecting Try It doesn't automatically copy the code to Cloud Shell. Example of Try It for Azure Cloud Shell
Go to https://shell.azure.com or select the Launch Cloud Shell button to open Cloud Shell in your browser.
Select the Cloud Shell button on the top-right menu bar in the Azure portal. Cloud Shell button in the Azure portal

To run the code in this article in Azure Cloud Shell:

  1. Launch Cloud Shell.
  2. Select the Copy button on a code block to copy the code.
  3. Paste the code into the Cloud Shell session with Ctrl+Shift+V on Windows and Linux, or Cmd+Shift+V on macOS.
  4. Press Enter to run the code.

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.

Example script

#!/bin/bash

# Allow Azure Batch to access the subscription (one-time operation).
az role assignment create \
    --assignee MicrosoftAzureBatch 
    --role contributor

# Create a resource group.
az group create --name myResourceGroup --location westeurope

# 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. 
az keyvault create \
    --resource-group myResourceGroup \
    --name mykevault \
    --location westeurope \
    --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 myResourceGroup \
    --name mykevault \
    --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.
az batch account create \
    --resource-group myResourceGroup \
    --name mybatchaccount \
    --location westeurope \
    --keyvault mykevault

# 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 myResourceGroup -n mybatchaccount

Clean up deployment

Run the following command to remove the resource group and all resources associated with it.
