Create a Web App plus Azure Cache for Redis using a template

[!INCLUDE updated-for-az]

In this article, you learn how to create an Azure Resource Manager template that deploys an Azure Web App with Azure Cache for Redis. You'll learn the following deployment details:

• How to define which resources are deployed
• How to define parameters that are specified when the deployment is executed

You can use this template for your own deployments, or customize it to meet your requirements.

For more information about creating templates, see Authoring Azure Resource Manager templates. To learn about the JSON syntax and properties for cache resource types, see Microsoft.Cache resource types.

For the complete template, see Web App with Azure Cache for Redis template.

What you will deploy

In this template, you deploy:

• Azure Web App
• Azure Cache for Redis

To run the deployment automatically, select the following button:

Parameters to specify

[!INCLUDE app-service-web-deploy-web-parameters]

[!INCLUDE cache-deploy-parameters]

Variables for names

This template uses variables to construct names for the resources. It uses the uniqueString function to construct a value based on the resource group id.

"variables": {
  "hostingPlanName": "[concat('hostingplan', uniqueString(resourceGroup().id))]",
  "webSiteName": "[concat('webSite', uniqueString(resourceGroup().id))]",
  "cacheName": "[concat('cache', uniqueString(resourceGroup().id))]"
},

Resources to deploy

[!INCLUDE app-service-web-deploy-web-host]

Azure Cache for Redis

Creates the Azure Cache for Redis that is used with the web app. The name of the cache is specified in the cacheName variable.

The template creates the cache in the same location as the resource group.

{
  "name": "[variables('cacheName')]",
  "type": "Microsoft.Cache/Redis",
  "location": "[resourceGroup().location]",
  "apiVersion": "2015-08-01",
  "dependsOn": [ ],
  "tags": {
    "displayName": "cache"
  },
  "properties": {
    "sku": {
      "name": "[parameters('cacheSKUName')]",
      "family": "[parameters('cacheSKUFamily')]",
      "capacity": "[parameters('cacheSKUCapacity')]"
    }
  }
}

Web app (Azure Cache for Redis)

Creates the web app with name specified in the webSiteName variable.

Notice that the web app is configured with app setting properties that enable it to work with the Azure Cache for Redis. These app settings are dynamically created based on values provided during deployment.

{
  "apiVersion": "2015-08-01",
  "name": "[variables('webSiteName')]",
  "type": "Microsoft.Web/sites",
  "location": "[resourceGroup().location]",
  "dependsOn": [
    "[concat('Microsoft.Web/serverFarms/', variables('hostingPlanName'))]"
  ],
  "tags": {
    "[concat('hidden-related:', resourceGroup().id, '/providers/Microsoft.Web/serverfarms/', variables('hostingPlanName'))]": "empty",
    "displayName": "Website"
  },
  "properties": {
    "name": "[variables('webSiteName')]",
    "serverFarmId": "[resourceId('Microsoft.Web/serverfarms', variables('hostingPlanName'))]"
  },
  "resources": [
    {
      "apiVersion": "2015-08-01",
      "type": "config",
      "name": "appsettings",
      "dependsOn": [
        "[concat('Microsoft.Web/Sites/', variables('webSiteName'))]",
        "[concat('Microsoft.Cache/Redis/', variables('cacheName'))]"
      ],
      "properties": {
       "CacheConnection": "[concat(variables('cacheHostName'),'.redis.cache.windows.net,abortConnect=false,ssl=true,password=', listKeys(resourceId('Microsoft.Cache/Redis', variables('cacheName')), '2015-08-01').primaryKey)]"
      }
    }
  ]
}

Web app (RedisEnterprise)

For RedisEnterprise, because the resource types are slightly different, the way to do listKeys is different:

{
  "apiVersion": "2015-08-01",
  "name": "[variables('webSiteName')]",
  "type": "Microsoft.Web/sites",
  "location": "[resourceGroup().location]",
  "dependsOn": [
    "[concat('Microsoft.Web/serverFarms/', variables('hostingPlanName'))]"
  ],
  "tags": {
    "[concat('hidden-related:', resourceGroup().id, '/providers/Microsoft.Web/serverfarms/', variables('hostingPlanName'))]": "empty",
    "displayName": "Website"
  },
  "properties": {
    "name": "[variables('webSiteName')]",
    "serverFarmId": "[resourceId('Microsoft.Web/serverfarms', variables('hostingPlanName'))]"
  },
  "resources": [
    {
      "apiVersion": "2015-08-01",
      "type": "config",
      "name": "appsettings",
      "dependsOn": [
        "[concat('Microsoft.Web/Sites/', variables('webSiteName'))]",
        "[concat('Microsoft.Cache/RedisEnterprise/databases/', variables('cacheName'), "/default")]",
      ],
      "properties": {
       "CacheConnection": "[concat(variables('cacheHostName'),abortConnect=false,ssl=true,password=', listKeys(resourceId('Microsoft.Cache/RedisEnterprise', variables('cacheName'), 'default'), '2020-03-01').primaryKey)]"
      }
    }
  ]
}
