CLI example: Create a Batch account in Batch service mode

This script creates an Azure Batch account in Batch service mode and shows how to query or update various properties of the account. When you create a Batch account in the default Batch service mode, its compute nodes are assigned internally by the Batch service. Allocated compute nodes are subject to a separate vCPU (core) quota and the account can be authenticated either via shared key credentials or an Azure Active Directory token.

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

Prerequisites

You can use either the Azure Cloud Shell or a local Azure CLI.

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 <Subscription ID> with your Azure Subscription ID. If you don't have an Azure subscription, create an Azure free account before you begin.

subscription="<subscriptionId>" # add subscription 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 Batch service mode

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

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

# Create a Batch account
echo "Creating $batchAccount"
az batch account create --resource-group $resourceGroup --name $batchAccount --location "$location"

# Display the details of the created account.
az batch account show --resource-group $resourceGroup --name $batchAccount

# Add a storage account reference to the Batch account for use as 'auto-storage'
# for applications. Start by creating the storage account.
echo "Creating $storageAccount"
az storage account create --resource-group $resourceGroup --name $storageAccount --location "$location" --sku Standard_LRS

# Update the Batch account with the either the name (if they exist in
# the same resource group) or the full resource ID of the storage account.
echo "Adding $storageAccount to $batchAccount"
az batch account set --resource-group $resourceGroup --name $batchAccount --storage-account $storageAccount

# View the access keys to the Batch Account for future client authentication.
az batch account keys list --resource-group $resourceGroup --name $batchAccount

# Authenticate against the account directly for further CLI interaction.
az batch account login --resource-group $resourceGroup --name $batchAccount --shared-key-auth

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

Sample reference

This script uses the following commands. Each command in the table links to command-specific documentation.

az batch account create Creates the Batch account.
az storage account create Creates a storage account.
az batch account set Updates properties of the Batch account.

az batch account keys list Retrieves the access keys of the specified Batch account.
az batch account login Authenticates against the specified Batch account for further CLI interaction.
az group delete Deletes a resource group including all nested resources.
