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
Use the Bash environment in Azure Cloud Shell. For more information, see Azure Cloud Shell Quickstart - Bash.
If you prefer to run CLI reference commands locally, install the Azure CLI. If you are 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 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 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
