Create a function app for serverless code execution

This Azure Functions sample script creates a function app, which is a container for your functions. The function app is created using the Consumption plan, which is ideal for event-driven serverless workloads.

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

Prerequisites

You can use the local Azure CLI.

• If you prefer, install the Azure CLI to run CLI reference commands.

• Local Azure CLI, see how to 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.

  • 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

Run the script

#!/bin/bash

# <FullScript>
# Function app and storage account names must be unique.

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="chinanorth2"
resourceGroup="msdocs-azure-functions-rg-$randomIdentifier"
tag="create-function-app-consumption"
storage="msdocsaccount$randomIdentifier"
functionApp="msdocs-serverless-function-$randomIdentifier"
skuStorage="Standard_LRS"
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 serverless function app in the resource group.
echo "Creating $functionApp"
az functionapp create --name $functionApp --storage-account $storage --consumption-plan-location "$location" --resource-group $resourceGroup --functions-version $functionsVersion
# </FullScript>

# echo "Deleting all resources"
# az group delete --name $resourceGroup -y

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
