Please complete the following steps in the listed order to configure your installed instance of the  Designer Cloud powered by Trifacta® platform  to integrate with the running environment cluster.

Prerequisites

  1. Deploy running environment cluster and Trifacta node.

    NOTE: The running environment cluster can be deployed as part of the installation process. You can also integrate the platform with a pre-existing cluster. Details are below.

  2. Install  Designer Cloud powered by Trifacta platform  on the node.

For more information, see Install for Azure.

Configure Azure

Create registered application

You must create an Azure Active Directory (AAD) application and grant it the desired access permissions, such as read/write access to resources and read/write access to the Azure Key Vault secrets.

NOTE: If you are integrating with Azure Databricks and are Managed Identities for authentication, please skip this section. That configuration is covered in a later step.

This service principal is used by the Designer Cloud powered by Trifacta platform for access to all Azure resources. For more information, see https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-service-principal-portal.

After you have registered, acquire the following information:

Azure PropertyLocationUse
Application ID

Acquire this value from the Registered app blade of the Azure Portal.

Applied to Designer Cloud powered by Trifacta platform configuration: azure.applicationid.

Service User Key

Create a key for the Registered app in the Azure Portal.

Applied to Designer Cloud powered by Trifacta platform  configuration: azure.secret.

NOTE: If you are using Azure AD to integrate with an Azure Databricks cluster, the Azure AD secret value stored in azure.secret must begin with an alphanumeric character. This is a known issue.

Directory IDCopy the Directory ID from the Properties blade of Azure Active Directory.

Applied to Designer Cloud powered by Trifacta platform  configuration: azure.directoryId.

To create an Azure Active Directory (AAD) application, please complete the following steps in the Azure console.

Steps:

  1. Create registered application:

    1. In the Azure console, navigate to Azure Active Directory > App Registrations.

    2. Create a New App. Name it trifacta.

      NOTE: Retain the Application ID and Directory ID for configuration in the Designer Cloud powered by Trifacta platform .

  2. Create a client secret:
    1. Navigate to Certificates & secrets.
    2. Create a new Client secret.

      NOTE: Retain the value of the Client secret for configuration in the Designer Cloud powered by Trifacta platform .

  3. Add API permissions:
    1. Navigate to API Permissions.
    2. Add Azure Key Vault with the user_impersonation permission.

These properties are applied later in the configuration process.
