Task 6: Create a Service Connection for Resource Group Deployment using Managed Identity and Workload Identity Federation

Step 1: Understand the Requirements

You want to deploy resources in the RGHod489Q1628 resource group.

The service connection must:

Use the ManagedJd1 managed identity.

Use workload identity federation (OIDC-based authentication for enhanced security).

Step 2: Verify Prerequisites

You need to ensure:

The ManagedJd1 managed identity exists in your Azure subscription.

Your Azure DevOps project (Project1) is linked to an Azure Active Directory tenant (for OIDC support).

You have the Owner or User Access Administrator role on the RGHod489Q1628 resource group.

Step 3: Assign Role to Managed Identity

Go to the Azure Portal.

In the search bar, type Managed Identities and select Managed Identities.

Locate and click on the ManagedJd1 identity.

In the left menu, click Azure role assignments.

Click + Add role assignment.

Set the following:

Scope: Resource Group

Subscription: Your subscription

Resource Group: RGHod489Q1628

Role: Contributor (or appropriate role)

Click Save.

This step ensures ManagedJd1 has permissions to deploy resources to RGHod489Q1628.

Step 4: Create a Federated Credential for Workload Identity Federation

In the Azure Portal, navigate to the ManagedJd1 managed identity.

In the left menu, click Workload identity federation (preview).

Click + Add a federated credential.

Configure as follows:

Federated credential name: devops-oidc

Issuer: (or use the default for Azure DevOps)

Subject identifier: Use the following format for Azure DevOps:

css

Copy

system:azuredevops:{organizationName}:{projectName}

For example:

css

Copy

system:azuredevops:{YourOrganizationName}:{Project1}

Audience: api://AzureADTokenExchange

Click Add.

This federated credential establishes trust between your Azure DevOps project and the managed identity.

Step 5: Create a Service Connection in Azure DevOps

Go to your Azure DevOps project (Project1) in the browser.

In the left menu, click Project settings.

Under Pipelines, click Service connections.

Click New service connection.

Choose Azure Resource Manager.

Choose the authentication method:

Select Workload identity federation.

Configure the service connection:

Scope level: Resource Group.

Resource Group: RGHod489Q1628.

Subscription: Your subscription.

Authentication method: Managed Identity with workload identity federation.

Managed Identity: Enter the client ID or select ManagedJd1.

Service connection name: e.g., Project1-RGHod489Q1628-Conn.

Grant access permission to all pipelines (recommended).

Click Save.

Step 6: Validate the Service Connection

After creation, click on the new service connection to Verify it.

Ensure the connection test is successful.

You can now use this service connection in your pipelines for deploying resources to RGHod489Q1628.

Task 8: Create a Service Hook to Integrate with Azure Storage (queue1)

Step 1: Verify the Storage Account and Queue

In the Azure portal ( ):

Go to Storage accounts.

Find the storage48901628 storage account.

In the left menu, click on Queues.

Ensure that a queue named queue1 exists.If not, create it by:

Clicking + Queue.

Enter Name: queue1.

Click OK.

Step 2: Prepare the Storage Account’s Shared Access Signature (SAS)

Azure DevOps uses SAS tokens to send messages to a storage queue.

In the Azure portal, go to the storage48901628 storage account.

In the left menu, click Shared access signature.

Set the following:

Allowed services: Queue.

Allowed resource types: Object.

Allowed permissions: Add, Write.

Start and expiry date/time: Adjust as needed (e.g., 1 year).

Click Generate SAS and connection string.

Copy the Queue SAS URL (e.g.,

Step 3: Create the Service Hook in Azure DevOps

In your Azure DevOps Project (Project1):

In the bottom-left, click Project settings.

In the left menu, click Service hooks.

Click + Create subscription.

Step 4: Configure the Azure Storage Service Hook

In the Create a subscription wizard, choose Azure Storage Queues and click Next.

Choose the Trigger:

For example: Code pushed (or other events you want to send to the queue).

Click Next.

Configure the Action:

Queue endpoint URL: The Queue SAS URL you copied in Step 2 (including the queue1 endpoint and SAS token).

Example:

bash

Copy

Step 5: Finalize and Test the Integration

Click Test to ensure Azure DevOps can send a message to the queue.

If the test succeeds, click Finish to create the service hook.

Step 6: Validate in the Azure Portal

In the Azure portal, go to storage48901628 > Queues > queue1.

You should see new messages appear in the queue whenever the configured Azure DevOps event (like push or PR) occurs.

To ensure that your Azure Web App namedaz400-38443478-maincan retrieve secrets from an Azure Key Vault namedaz400-3844J478-kv1using a system managed identity with the principle of least privilege, follow these detailed steps:

Enable a System Managed Identity for the Azure Web App:

Navigate to the Azure Portal.

Go to the Azure Web Appaz400-38443478-main.

SelectIdentityunder theSettingssection.

In theSystem assignedtab, switch theStatustoOn.

ClickSaveto apply the changes.

Grant the Web App Access to the Key Vault:

Go to the Azure Key Vaultaz400-3844J478-kv1.

SelectAccess policiesunder theSettingssection.

Click onAdd Access Policy.

ChooseSecret permissionsand selectGetandList. This grants the app the ability to read secrets, adhering to the principle of least privilege.

Click onSelect principal, search for your Web App nameaz400-38443478-main, and select it.

ClickAddto add the policy.

Don’t forget to clickSaveto save the access policy changes.

Retrieve Secrets in the Web App Code:

In your Web App’s code, use the Azure SDK to retrieve the secrets.

For example, in a .NET application,you can use theAzure.IdentityandAzure.Security.KeyVault.Secretsnamespaces.

Utilize theDefaultAzureCredentialclass which will automatically use the system managed identity when running on Azure.

using Azure.Identity;

usingAzure.Security.KeyVault.Secrets;

var client = new SecretClient(new Uri(" "), new DefaultAzureCredential());

KeyVaultSecret secret = await client.GetSecretAsync("my-secret-name");

string secretValue =secret.Value;

Replace"my-secret-name"with the actual name of the secret you want to retrieve.

By following these steps, your Azure Web App will be able to securely retrieve secrets from the Azure Key Vault using a system managed identity, without needingto store credentials in the code, and adhering to the principle of least privilege. Remember to replace the placeholder names with the actual names of your Web App and Key Vault.

1.Go to the Azure portal, navigate to Traffic Manager profiles and click on the Add button to create a routing profile.

2. In the Create Traffic Manager profile, enter, or select these settings:

Name: az40011566895n1-tm

Routing method: Geographic

Resource group: RG1lod11566895

Note: Traffic Manager profiles can be configured to use the Geographic routing method so that users are directed to specific endpoints (Azure, External or Nested) based on which geographic location their DNS query originates from. This empowers Traffic Manager customers to enable scenarios where knowing a user’s geographic region and routing them based on that is important.
