Create a function app with a named Storage account connection

This Azure Functions sample script creates a function app and connects the function to an Azure Storage account. The created app setting that contains the connection can be used with a storage trigger or binding.

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

Prerequisites

  • 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 sample creates an Azure Function app and adds the storage connection string to an app setting.

#!/bin/bash

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

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

# Create a 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 \
  --resource-group myResourceGroup \
  --storage-account $storageName \
  --consumption-plan-location $region \
  --functions-version 2

# Get the storage account connection string. 
connstr=$(az storage account show-connection-string --name $storageName --resource-group myResourceGroup --query connectionString --output tsv)

# Update function app settings to connect to the storage account.
az functionapp config appsettings set \
  --name $functionAppName \
  --resource-group myResourceGroup \
  --settings StorageConStr=$connstr

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
