Create a function app in a Premium plan - Azure CLI

This Azure Functions sample script creates a function app, which is a container for your functions. The function app that is created uses a scalable Premium plan.

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 <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

# Function app and storage account names must be unique.

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="eastus"
resourceGroup="msdocs-azure-functions-rg-$randomIdentifier"
tag="create-function-app-premium-plan"
storage="msdocsaccount$randomIdentifier"
premiumPlan="msdocs-premium-plan-$randomIdentifier"
functionApp="msdocs-function-$randomIdentifier"
skuStorage="Standard_LRS" # Allowed values: Standard_LRS, Standard_GRS, Standard_RAGRS, Standard_ZRS, Premium_LRS, Premium_ZRS, Standard_GZRS, Standard_RAGZRS
skuPlan="EP1"
functionsVersion="4"

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

# Create an Azure storage account in the resource group.
echo "Creating $storage"
az storage account create --name $storage --location "$location" --resource-group $resourceGroup --sku $skuStorage

# Create a Premium plan
echo "Creating $premiumPlan"
az functionapp plan create --name $premiumPlan --resource-group $resourceGroup --location "$location" --sku $skuPlan

# Create a Function App
echo "Creating $functionApp"
az functionapp create --name $functionApp --storage-account $storage --plan $premiumPlan --resource-group $resourceGroup --functions-version $functionsVersion

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

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

Command	Notes

az storage account create	Creates an Azure Storage account.
az functionapp plan create	Creates a Premium plan in a specific SKU.
az functionapp create	Creates a function app in the App Service plan.
