Scenario: By default, all releases must remain available for 30 days, except for production releases, which must be kept for 60 days.

Box 1: Set the defaultretention policy to 30 days

The Global default retention policy sets the default retention values for all the build pipelines. Authors of build pipelines can override these values.

Box 2: Set the stage retention policy to 60 days

You may want to retain more releases that have been deployed to specific stages.

Woodgrove Bank plans to implement the following changes to the identity environment:

Configure App1 to use a service principal.

Scenario: Access to Azure DevOps mustbe restricted to specific IP addresses.

Azure DevOps is authenticated through Azure Active Directory. You can use Azure AD's conditional access to prevent logins from certain geographies and address ranges.

Step 1: Log in to the Azure Portal

Go to https://portal.azure.com .

Log in with your Azure account.

Step 2: Create an Azure App Configuration Instance

In the search bar at the top, type “App Configuration” and select App Configuration from the search results.

Click + Create.

Fill in the required fields:

Subscription: Your Azure subscription.

Resource Group: Create a new one or select an existing one.

Name: Provide a globally unique name (for example, myappconfig-instance).

Location: Choose a region close to your application.

Click Review + Create, then Create.

The instance will take a few seconds to deploy.

Step 3: Access the App Configuration Instance

Once the deployment is complete, click Go to resource.

You are now in the App Configuration resource.

Step 4: Enable Feature Management

In the left menu, click on Feature Manager (Preview).

Click + Add to create a new feature flag.

Step 5: Create the Feature Flag

You can usea system-assigned managed identity for a Windows virtual machine (VM) to access Azure Key Vault.

Sign in to Azure portal

Locate virtual machine VM1.

Select Identity

Enable the system-assigned identity for VM1 by setting the Status to On.

Note:Enabling a system-assigned managed identity is a one-click experience. You can either enable it during the creation of a VM or in the properties of an existing VM.

Step 1: Understand the Requirements

You need to create a self-hosted agent for Azure Pipelines.

It will be hosted in a pod (for example, in Kubernetes).

All pipelines in Project1 should be able to use this agent pool named Pool1.

Step 2: Create the Agent Pool in Azure DevOps

Go to your Azure DevOps organization:https://dev.azure.com/{YourOrganizationName}

In the bottom-left corner, click on the Organization settings gear icon.

In the left menu, click on Agent pools.

Click on Add pool.

Provide the following:

Pool name: Pool1

Pool type: Self-hosted

Grant access permission to all pipelines: Checked (so that all Project1 pipelines can use this pool)

Click Create.

Now you have an empty agent pool named Pool1.

Step 3: Prepare the Self-hosted Agent as a Pod

You need to deploy an Azure Pipelines agent container as a pod. Here’s how to do it:

Option 1: Using Kubernetes directly (YAML deployment)

Create a Kubernetes deployment YAML file for the agent pod:

apiVersion: apps/v1

kind: Deployment

metadata:

name: azure-pipelines-agent

labels:

app: azure-pipelines-agent

spec:

replicas: 1

selector:

matchLabels:

app: azure-pipelines-agent

template:

metadata:

labels:

app: azure-pipelines-agent

spec:

containers:

- name: agent

image: mcr.microsoft.com/azure-pipelines/vsts-agent:latest

env:

- name: AZP_URL

value: "https://dev.azure.com/{YourOrganizationName} "

- name: AZP_TOKEN

valueFrom:

secretKeyRef:

name: azure-pipelines-token

key: token

- name: AZP_POOL

value: "Pool1"

- name: AZP_AGENT_NAME

value: "agent-pod"

Create a Kubernetes secret for the personal access token (PAT):

kubectl create secret generic azure-pipelines-token --from-literal=token=

Note:

Replace with a PAT that has “Agent Pools (Read & manage)” scope.

Replace {YourOrganizationName} with your actual Azure DevOps organization.

Deploy the pod:

bash

Copy

kubectl apply -f azure-pipelines-agent.yaml

Step 4: Validate the Agent Connection

Go back to Organization Settings > Agent pools > Pool1 in Azure DevOps.

You should see the agent pod connected and listed as online.

Step 5: Use the Pool in Pipelines

By default, all pipelines in Project1 will now have access to the Pool1 agent pool because you granted access during the pool creation.

In your pipeline YAML files, specify the pool name to use the self-hosted agent:

yaml

Copy

pool:

name: Pool1

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: https://vstoken.actions.githubusercontent.com (or use the default https://pipelines.actions.githubusercontent.com 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.
