Connect an App Service app to a storage account using CLI

This sample script creates an Azure storage account and an App Service app. It then links the storage account to the app using app settings.

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

Open Azure Cloud Shell

Azure Cloud Shell is a free, interactive shell that you can use to run the steps in this article. Common Azure tools are preinstalled and configured in Cloud Shell for you to use with your account. Select Copy to copy the code, paste it in Cloud Shell, and then press Enter to run it. There are a few ways to open Cloud Shell:

Select Try It in the upper-right corner of a code block. Example of Try It for Azure Cloud Shell
Open Cloud Shell in your browser. Launch Azure Cloud Shell button
Select the Cloud Shell button on the menu in the upper-right corner of the Azure portal. Cloud Shell button in the Azure portal

If you choose to install and use the CLI locally, you need Azure CLI version 2.0 or later. To find the version, run az --version. If you need to install or upgrade, see Install the Azure CLI.

Sample script

#/bin/bash

# Variables
appName="webappwithstorage$RANDOM"
storageName="webappstorage$RANDOM"
location="westeurope"

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

# Create an App Service plan
az appservice plan create --name myAppServicePlan --resource-group myResourceGroup \
--location $location

# Create a web app
az webapp create --name $appName --plan myAppServicePlan --resource-group myResourceGroup 

# Create a storage account
az storage account create --name $storageName --resource-group myResourceGroup \
--location $location --sku Standard_LRS

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

# Assign the connection string to an App Setting in the Web App
az webapp config appsettings set --name $appName --resource-group myResourceGroup \
--settings "STORAGE_CONNSTR=$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.
