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 free account before you begin.

Prerequisites

  • Use the Bash environment in Azure Cloud Shell.

    Launch Cloud Shell in a new window

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

    • 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 additional sign-in options, see Sign in with the Azure CLI.

    • When you're prompted, install Azure CLI extensions 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.

  • This tutorial requires version 2.0 or later of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.

Sample script

This script creates an Azure Function app using the Consumption plan.

#!/bin/bash

# Function app and storage account names must be unique.
storageName=mystorageaccount$RANDOM
functionAppName=myserverlessfunc$RANDOM
region=westeurope

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

# Create an Azure storage account in the resource group.
az storage account create \
  --name $storageName \
  --location $region \
  --resource-group myResourceGroup \
  --sku Standard_LRS

# Create a serverless function app in the resource group.
az functionapp create \
  --name $functionAppName \
  --storage-account $storageName \
  --consumption-plan-location $region \
  --resource-group myResourceGroup \
  --functions-version 2
  

Clean up deployment

After the sample script has been run, the following command can be used to remove the resource group and all resources associated with it.

az group delete --name myResourceGroup
