Enable Remote Debugging

Before we start a debugging session to our Azure Function app we need to enable the functionality.

Navigate in the Azure portal to your function app fa-11566895

Go to the “Application settings”

Under “Debugging” set Remote Debugging to On and set Remote Visual Studio version to 2017.

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= < your-PAT >

Note:

Replace < your-PAT > 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

Step 1: Initialize the Default Main Branch

Navigate to Azure DevOps:

Go to Azure DevOps and sign in with your credentials.

Select Your Project:

Choose Project1 from your list of projects.

Initialize the Main Branch:

Goto Repos  >  Files.

If the main branch does not exist, you will see an option to initialize it. Click on Initialize and follow the prompts to create the main branch1.

Step 2: Enable Squash Merge for the Main Branch

Navigate to Branch Policies:

Go to Repos  >  Branches.

Find the main branch and click on the … (ellipsis) next to it.

Select Branch policies.

Enable Squash Merge:

Under Policies, scroll down to the Merge strategy section.

Select Squash merge as the required mergestrategy2.

Save Changes:

Click on Save changes to apply the policies.

Step 3: Verify the Squash Merge Policy

Create a Pull Request:

Make achange in a branch and create a pull request to merge it into the main branch.

Complete the Pull Request:

Ensure that the pull request uses thesquash merge strategy by selecting Squash commit under the Merge type in the Complete pull request dialog

Step 1: Sign Up for Azure DevOps

Navigate to Azure DevOps.

Click on Start Free.

Enter the credentials:

Email: UserUsefl-42147509@ExamUsers.com

Password: eWrSalD2!

Follow the prompts to complete the sign-up process using the default settings.

Step 2: Create an Azure DevOps Organization

Once signed in, you will be prompted to create a new organization.

Enter a name for your organization and select your region.

Click on Continue to create the organization.

Step 3: Create a Private Project

In your new organization, click on New Project.

Name the project Project1.

Set the visibility to Private.

Click on Create.

Step 4: Add an External User as a Stakeholder

Go to the Organization Settings.

Under General, select Users.

Click on Add users.

Enter the email address: Usfrr2-42147S09@ExamUsers.com.

Set the access level to Stakeholder.

Add the user to the most restrictive group, which is typically the Readers group.

Click on Add to complete the process.

Step 5: Verify the User Addition

Ensure that the external user has been added successfully by checking the Users list.

Confirm that the user has the Stakeholder access level and is part of the Readers group.

By following thesesteps, you should be able to complete the task successfully. If you encounter any issues, feel free to ask for further assistance!

To prepare a Network Security Group (NSG) namedaz400-38443478-nsg1for hosting an Azure DevOps pipeline agent, while allowing only the required outbound port for Azure DevOps and denying all other inbound and outbound access to the Internet, follow these steps:

Create the NSG:

Navigate to the Azure Portal.

Go toNetwork Security Groupsand click on+ Create.

Fill in the details, including the nameaz400-38443478-nsg1, and create the NS

G.  

ConfigureOutbound Security Rules:

Once the NSG is created, go to its settings.

Navigate toOutbound security rules.

Click on+ Addto create a new rule.

Set theDestination port rangesto443, which is the required port for Azure DevOps12.

Set theProtocoltoTCP.

Set theActiontoAllow.

Assign aPrioritynumber (e.g.,100) that does not conflict with existing rules.

Provide a meaningfulNamefor the rule (e.g.,AllowAzureDevOps).

Configure Default Rules to Deny All Other Traffic:

In the sameOutbound security rulessection, edit the default rule to deny alltraffic.

Change theActiontoDenyfor the rule with the lowest priority (highest number).

Ensure that this rule applies to all protocols, source and destination IP ranges, and port ranges.

Associate the NSG with the Appropriate Resource:

Associate the NSGwith the subnet or network interface of the virtual machine or resource where the Azure DevOps pipeline agent will be hosted.

By following these steps, you will ensure that the Azure DevOps pipeline agent can communicate with Azure DevOps services over the required port while blocking all other inbound and outbound Internet access, adhering to the principle of least privilege and security best practices.
