Microsoft Azure AZ-400 Question # 308 Topic 31 Discussion

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
