Connect an App Service app to an Azure Cache for Redis using CLI

This sample script creates an Azure Cache for Redis and an App Service app. It then links the Azure Cache for Redis to the app using app settings.

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

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 Azure CLI.

Sample script

#/bin/bash

# Variables
appName="webappwithredis$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 Redis Cache
redis=($(az redis create --name $appName --resource-group myResourceGroup \
--location $location --vm-size C0 --sku Basic --query [hostName,sslPort] --output tsv))

# Get access key
key=$(az redis list-keys --name $appName --resource-group myResourceGroup \
--query primaryKey --output tsv)

# Assign the connection string to an App Setting in the Web App
az webapp config appsettings set --name $appName --resource-group myResourceGroup \
 --settings "REDIS_URL=${redis[0]}" "REDIS_PORT=${redis[1]}" "REDIS_KEY=$key"

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
