CLI example: Add an application to an Azure Batch account

This script demonstrates how to add an application for use with an Azure Batch pool or task. To set up an application to add to your Batch account, package your executable, together with any dependencies, into a zip file.

If you don't have an Azure account, create a trial account before you begin.

Prerequisites

• 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

Sign in to Azure

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 account, create a trial account before you begin.

az cloud set -n AzureChinaCloud
az login

subscription="<subscriptionId>" # add subscription here

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

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

Create batch account and new application

# Add an application to an Azure Batch account

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="China North 3"
[[ "$RESOURCE_GROUP" == '' ]] && resourceGroup="msdocs-batch-rg-$randomIdentifier" || resourceGroup="${RESOURCE_GROUP}"
tag="add-application"
storageAccount="msdocsstorage$randomIdentifier"
batchAccount="msdocsbatch$randomIdentifier"

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

# Create a general-purpose storage account in your resource group.
echo "Creating $storageAccount"
az storage account create --resource-group $resourceGroup --name $storageAccount --location "$location" --sku Standard_LRS

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

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

# Create a new application.
az batch application create --resource-group $resourceGroup --name $batchAccount --application-name "MyApplication"

Create batch application package

An application can reference multiple application executable packages of different versions. The executables and any dependencies need to be zipped up for the package. Once uploaded, the CLI attempts to activate the package so that it's ready for use.

az batch application package create \
    --resource-group $resourceGroup \
    --name $batchAccount \
    --application-name "MyApplication" \
    --package-file my-application-exe.zip \
    --version-name 1.0

Update the application

Update the application to assign the newly added application package as the default version.

az batch application set \
    --resource-group $resourceGroup \
    --name $batchAccount \
    --application-name "MyApplication" \
    --default-version 1.0

Clean up resources

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

az group delete --name $resourceGroup
