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.

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. Open 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, 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.

az group delete --name myResourceGroup
