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.

The function app created by this script uses version 1.x of the Azure Functions runtime. To learn how to upgrade to version 2.x, see Target a version using Azure CLI.

Use Azure Cloud Shell

Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. Cloud Shell lets you use either bash or PowerShell to work with Azure services. You can use the Cloud Shell pre-installed commands to run the code in this article without having to install anything on your local environment.

To launch Azure Cloud Shell:

Option Example/Link
Select Try It in the upper-right corner of a code block. Selecting Try It doesn't automatically copy the code to Cloud Shell. Example of Try It for Azure Cloud Shell
Go to https://shell.azure.com or select the Launch Cloud Shell button to open Cloud Shell in your browser. Launch Cloud Shell in a new window
Select the Cloud Shell button on the top-right menu bar in the Azure portal. Cloud Shell button in the Azure portal

To run the code in this article in Azure Cloud Shell:

  1. Launch Cloud Shell.
  2. Select the Copy button on a code block to copy the code.
  3. Paste the code into the Cloud Shell session with Ctrl+Shift+V on Windows and Linux, or Cmd+Shift+V on macOS.
  4. Press Enter to run the code.

If you choose to install and use the CLI locally, this article requires that you are running the Azure CLI version 2.0 or later. Run az --version to find the version. If you need to install or upgrade, see Install the Azure CLI.

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

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

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

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
