Important

Before you run the resource provider installer, you must complete the steps in Before you get started

In this article you learn how to deploy the Azure App Service resource provider to an Azure Stack Hub environment that is:

  • Connected or disconnected from the internet
  • Secured by Entra ID or Active Directory Federation Services (AD FS).

To add the Azure App Service resource provider to your Azure Stack Hub deployment, you must complete these top-level tasks:

  1. Complete the prerequisite steps (like purchasing certificates, which can take a few days to receive).
  2. Download and extract the installation and helper files.
  3. Download the offline installation package.
  4. Run the appservice.exe installer file.

Complete the installation of Azure App Service on Azure Stack Hub

  1. Run appservice.exe as an admin from a computer that can reach the Azure Stack Hub Admin Azure Resource Management endpoint.

  2. Select Advanced > Complete offline installation.

  4. Review and accept the Microsoft Software License Terms, and then select Next.

  5. Review and accept the third-party license terms, and then select Next.

  6. Make sure the Azure App Service cloud configuration info is correct. If you used the default settings during Azure Stack Development Kit deployment, you can accept the default values here. However, if you customized the options when you deployed Azure Stack Hub or are deploying on an integrated system, you must edit the values in this window to reflect those changes. For example, if you use the domain suffix mycloud.com, your Azure Stack Hub Tenant Azure Resource Manager endpoint must change to management.<region>.mycloud.com. After you confirm your info, select Next.

    Configure Azure App Service cloud in Azure App Service Installer

  7. On the next App Service Installer page you'll connect to your Azure Stack Hub:

    1. Select the connection method you wish to use - Credential or Service Principal

      • Credential
        • If you're using Microsoft Entra ID, enter the Microsoft Entra admin account and password that you provided when you deployed Azure Stack Hub. Select Connect.
        • If you're using Active Directory Federation Services (AD FS), provide your admin account. For example, cloudadmin@azurestack.local. Enter your password, and then select Connect.
      • Service Principal
        • The service principal that you use must have Owner rights on the Default Provider Subscription
        • Provide the Service Principal ID, Certificate File, and Password and select Connect.

    2. In Azure Stack Hub Subscriptions, select the Default Provider Subscription. Azure App Service on Azure Stack Hub must be deployed in the Default Provider Subscription.

    3. In the Azure Stack Hub Locations, select the location that corresponds to the region you're deploying to. For example, select local if you're deploying to the ASDK.

    4. Administrators can specify a three character Deployment Prefix for the individual instances in each Virtual Machine Scale Set that are deployed. The Deployment Prefix is useful if managing multiple Azure Stack Hub instances.

  8. You can allow the Azure App Service installer to create a virtual network and associated subnets. Or, you can deploy into an existing virtual network, as configured through these steps.

    • To use the Azure App Service installer method, select Create VNet with default settings, accept the defaults, and then select Next.

    • To deploy into an existing network, select Use existing VNet and Subnets, and then:

      1. Select the Resource Group option that contains your virtual network.
      2. Choose the Virtual Network name you want to deploy into.
      3. Select the correct Subnet values for each of the required role subnets.
      4. Select Next.

  9. Enter the info for your file share and then select Next. The address of the file share must use the Fully Qualified Domain Name (FQDN) or IP address of your file server. For example: \\appservicefileserver.local.cloudapp.azurestack.external\websites, or \\10.0.0.1\websites. If you're using a domain-joined file server, you must provide the full user name, including the domain. For example: <myfileserverdomain>\<FileShareOwner>.

    Note

    The installer tries to test connectivity to the file share before proceeding. However, if you choose to deploy into an existing virtual network, the installer might be unable to connect to the file share and displays a warning asking whether you want to continue. Verify the file share info and continue if it's correct.

  10. On the next page:

    1. In the Identity Application ID box, enter the GUID for the Identity application you created as part of the prerequisites.
    2. In the Identity Application certificate file box, enter (or browse to) the location of the certificate file.
    3. In the Identity Application certificate password box, enter the password for the certificate. This password is the one that you made note of when you used the script to create the certificates.
    4. In the Azure Resource Manager root certificate file box, enter (or browse to) the location of the certificate file.
    5. Select Next.

    Enter app ID and certificate info in Azure App Service Installer

  11. For each of the three certificate file boxes, select Browse and navigate to the appropriate certificate file. You must provide the password for each certificate. These certificates are the ones that you created in Prerequisites for deploying App Service on Azure Stack Hub. Select Next after entering all the information.

    Box Certificate file name example
    App Service default SSL certificate file _.appservice.local.AzureStack.external.pfx
    App Service API SSL certificate file api.appservice.local.AzureStack.external.pfx
    App Service Publisher SSL certificate file ftp.appservice.local.AzureStack.external.pfx

    If you used a different domain suffix when you created the certificates, your certificate file names don't use local.AzureStack.external. Instead, use your custom domain info.

    Enter SSL certificate info in Azure App Service Installer

  12. Enter the SQL Server details for the server instance used to host the Azure App Service resource provider databases, and then select Next. The installer validates the SQL connection properties. You must enter either the internal IP or the FQDN for the SQL Server name.

    Note

    The installer tries to test connectivity to the computer running SQL Server before proceeding. However, if you chose to deploy into an existing virtual network, the installer might not be able to connect to the computer running SQL Server and displays a warning asking whether you want to continue. Verify the SQL Server info and continue if it's correct.

    From Azure App Service on Azure Stack Hub 1.3 onward, the installer checks that the computer running SQL Server has database containment enabled at the SQL Server level. If it doesn't, you're prompted with the following exception:

       Enable contained database authentication for SQL server by running below command on SQL server (Ctrl+C to copy)
   ***********************************************************
   sp_configure 'contained database authentication', 1;
   GO
   RECONFIGURE;
   GO
   ***********************************************************

    Enter SQL Server info in Azure App Service Installer

  13. Review the role instance and SKU options. The defaults populate with the minimum number of instances and the minimum SKU for each role in a production deployment. For ASDK deployment, you can scale the instances down to lower SKUs to reduce the core and memory commit but you'll experience a performance degradation. A summary of vCPU and memory requirements is provided to help plan your deployment. After you make your selections, select Next.

    Note

    For production deployments, follow the guidance in Capacity planning for Azure App Service server roles in Azure Stack Hub.

    Role Minimum instances Minimum SKU Notes
    Controller 2 Standard_A4_v2 - (4 cores, 8192 MB) Manages and maintains the health of the App Service cloud.
    Management 1 Standard_D3_v2 - (4 cores, 14336 MB) Manages the App Service Azure Resource Manager and API endpoints, portal extensions (admin, tenant, Functions portal), and the data service. To support failover, increase the recommended instances to 2.
    Publisher 1 Standard_A2_v2 - (2 cores, 4096 MB) Publishes content via FTP and web deployment.
    FrontEnd 1 Standard_A4_v2 - (4 cores, 8192 MB) Routes requests to App Service apps.
    Shared Worker 1 Standard_A4_v2 - (4 cores, 8192 MB) Hosts web or API apps and Azure Functions apps. You might want to add more instances. As an operator, you can define your offering and choose any SKU tier. The tiers must have a minimum of one vCPU.

    Set role tiers and SKU options in Azure App Service Installer

  14. In the Select Platform Image box, choose your prepared Windows Server 2022 Datacenter virtual machine (VM) image from the images available on the compute resource provider for the Azure App Service cloud. Select Next.

    Note

    Windows Server 2022 Core is not a supported platform image for use with Azure App Service on Azure Stack Hub. Don't use evaluation images for production deployments. Azure App Service on Azure Stack Hub requires that Microsoft .NET 3.5.1 SP1 is activated on the image used for deployment. Marketplace-syndicated Windows Server 2022 images don't have this feature enabled. Therefore, when deploying in offline environments, you must create and use a Windows Server 2022 image with this feature pre-enabled.

    See Prerequisites for deploying App Service on Azure Stack Hub for details on creating a custom image and adding to Marketplace. Be sure to specify the following when adding the image to Marketplace:

    • Publisher = MicrosoftWindowsServer
    • Offer = WindowsServer
    • SKU = AppService
    • Version = Specify the "latest" version

  15. On the next page:

    1. Enter the Worker Role VM admin user name and password.
    2. Enter the Other Roles VM admin user name and password.
    3. Select Next.

Post-deployment steps

Important

If you've provided the Azure App Service Resource Provider with a SQL Always On Instance, you must add the appservice_hosting and appservice_metering databases to an availability group. You must also synchronize the databases to prevent any loss of service in the event of a database failover.

If you chose to deploy into an existing virtual network and use an internal IP address to connect to your file server, you must add an outbound security rule, enabling SMB traffic between the worker subnet and the file server. In the administrator portal, go to the WorkersNsg Network Security Group and add an outbound security rule with the following properties:

  • Source: Any
  • Source port range: *
  • Destination: IP addresses
  • Destination IP address range: Range of IPs for your file server
  • Destination port range: 445
  • Protocol: TCP
  • Action: Allow
  • Priority: 700
  • Name: Outbound_Allow_SMB445

To remove latency when workers are communicating with the file server we also advise adding the following rule to the Worker Network Security Group to allow outbound LDAP and Kerberos traffic to your Active Directory Controllers if securing the file server using Active Directory, for example if you have used the Quickstart template to deploy a HA File Server and SQL Server.

Go to the WorkersNsg in the Admin Portal and add an outbound security rule with the following properties:

  • Source: Any
  • Source port range: *
  • Destination: IP Addresses
  • Destination IP address range: Range of IPs for your AD Servers, for example with the Quickstart template 10.0.0.100, 10.0.0.101
  • Destination port range: 389,88
  • Protocol: Any
  • Action: Allow
  • Priority: 710
  • Name: Outbound_Allow_LDAP_and_Kerberos_to_Domain_Controllers

Validate the Azure App Service on Azure Stack Hub installation

  1. In the Azure Stack Hub administrator portal, go to Administration - App Service.

  2. In the overview, under status, check to see that the Status displays All roles are ready.

    Overview in Azure App Service Administration

Test drive Azure App Service on Azure Stack Hub

After you deploy and register the Azure App Service resource provider, test it to make sure that users can deploy web and API apps.

Note

You must create an offer that has the Microsoft.Web namespace within the plan. Then, you need to have a tenant subscription that subscribes to this offer. For more info, see Create offer and Create plan.

You must have a tenant subscription to create apps that use Azure App Service on Azure Stack Hub. The only capabilities that a service admin can complete within the administrator portal are related to the resource provider administration of Azure App Service. These capabilities include adding capacity, configuring deployment sources, and adding Worker tiers and SKUs.

As of the third technical preview, to create web, API, and Azure Functions apps, you must use the user portal and have a tenant subscription.

  1. In the Azure Stack Hub user portal, select + Create a resource > Web + Mobile > Web App.

  2. On the Web App blade, type a name in the Web app box.

  3. Under Resource Group, select New. Type a name in the Resource Group box.

  4. Select App Service plan/Location > Create New.

  5. On the App Service plan blade, type a name in the App Service plan box.

  6. Select Pricing tier > Free-Shared or Shared-Shared > Select > OK > Create.

  7. In less than a minute, a tile for the new web app appears on the dashboard. Select the tile.

  8. On the Web App blade, select Browse to view the default website for this app.

Deploy a WordPress, DNN, or Django website (optional)

  1. In the Azure Stack Hub user portal, select +, go to Azure Marketplace, deploy a Django website, and wait for successful completion. The Django web platform uses a file system-based database. It doesn't require any other resource providers, such as SQL or MySQL.

  2. If you also deployed a MySQL resource provider, you can deploy a WordPress website from Azure Marketplace. When you're prompted for database parameters, enter the user name as User1@Server1, with the user name and server name of your choice.

  3. If you also deployed a SQL Server resource provider, you can deploy a DNN website from Azure Marketplace. When you're prompted for database parameters, choose a database on the computer running SQL Server that's connected to your resource provider.
