How do I configure an Azure AD Service Principal with Pulumi?

To configure an Azure AD Service Principal using Pulumi, you need to create an application and then create a service principal for that application. A service principal is an identity created for use with applications, hosted services, and automated tools to access Azure resources. Below is a detailed explanation followed by the code to achieve this.

1. Create an Azure AD Application: This application represents the application for which you want to create a service principal.
2. Create an Azure AD Service Principal: This service principal is associated with the application created in the previous step.

Here is the Pulumi program in TypeScript to configure an Azure AD Service Principal:

import * as pulumi from "@pulumi/pulumi";
import * as azuread from "@pulumi/azuread";

// Create an Azure AD Application
const adApp = new azuread.Application("exampleApp", {
    displayName: "example-app",
});

// Create a Service Principal for the Application
const servicePrincipal = new azuread.ServicePrincipal("exampleSp", {
    applicationId: adApp.applicationId,
});

// Export the Azure AD Application and Service Principal IDs
export const applicationId = adApp.applicationId;
export const servicePrincipalId = servicePrincipal.id;

Explanation:

• azuread.Application: This resource creates an Azure AD application. The displayName is set to “example-app”.
• azuread.ServicePrincipal: This resource creates a service principal for the Azure AD application. The applicationId property is set to the ID of the application created in the previous step.
• Exports: The program exports the applicationId and servicePrincipalId for reference.

Summary

This program demonstrates how to create an Azure AD application and a corresponding service principal using Pulumi. The application and service principal IDs are exported for use in other parts of your infrastructure.
