Azure Automation now ships with the Azure PowerShell module of version 0.8.6, which introduced the ability to non-interactively authenticate to Azure using OrgId (Azure Active Directory user) credential-based authentication. Using the steps below, you can set up Azure Automation to talk to Azure using this authentication type.

Step 1: Find the Azure Active Directory associated with the Azure subscription to manage:

1. Log in to the Azure portal as the service administrator for the Azure subscription you want to manage using Azure Automation. You can find this user by logging in to the Azure portal as any user with access to this Azure subscription, then clicking Settings, then Administrators.

2. Note the name of the directory associated with the Azure subscription you want to manage. You can find this directory by clicking Settings, then Subscriptions.

Step 2: Create an Azure Active Directory user in the directory associated with the Azure subscription to manage:

You can skip this step if you already have an Azure Active Directory user in this directory. and plan to use this OrgId to manage Azure.

1. In the Azure portal click on Active Directory service.

2. Click the directory name that is associated with this Azure subscription.

3. Click on the Users tab and then click the Add User button.

4. For type of user, select “New user in your organization.” Enter a username for the user to create.

5. Fill out the user’s profile. For role, pick “User.” Don’t enable multi-factor authentication. Multi-factor accounts cannot be used with Azure Automation.

6. Click Create.

7. Jot down the full username (including part after @ symbol) and temporary password.

Step 3: Allow this Azure Active Directory user to manage this Azure subscription.

1. Click on Settings (bottom Azure tab under StorSimple)

2. Click Administrators

3. Click the Add button. Type the full user name (including part after @ symbol) of the Azure Active Directory user you want to set up to manage Azure. For subscriptions, choose the Azure subscriptions you want this user to be able to manage. Click the check mark.

Step 4: Configure Azure Automation to use this Azure Active Directory user to manage this Azure subscription

Create an Azure Automation credential asset containing the username and password of the Azure Active Directory user that you have just created. You can create a credential asset in Azure Automation by clicking into an Automation Account and then clicking the Assets tab, then the Add Setting button.

Note: Once you have set up the Azure Active Directory credential in Azure and Azure Automation, you can now manage Azure from Azure Automation runbooks using this credential.

Pipeline artifacts are a way to persist build outputs, test results, and other files generated during a pipeline run. They allow you to share data between stages, jobs, and pipelines, and to persist data for longer than the lifetime of a pipeline run. While artifacts can be useful for sharing data between pipeline runs and reducing the time required to download dependencies, they are not a solution for reducing the time required to install JavaScript packages from 9pm during a pipeline run.

The solution of reducing the pipeline execution time could be achieved by using package caching, which allows you to store and reuse 9pm packages from previous pipeline runs. There are several package caching options available for Azure Pipelines, including the 9pm task, the 9pm cache task, and the 9pm ci task. All of these options allow you to configure caching for your 9pm packages, which can significantly reduce the time required to install packages during subsequent pipeline runs.

Another solution could be using a dedicated agent that has those packages already installed, this way the pipeline doesn't have to install them again.

You can find more information on package caching by following this link

Instead enable pipeline caching.

Note:

npm-cache is a command line utility that caches dependencies installed via npm, bower, jspm and composer.

It is useful for build processes that run [npm|bower|composer|jspm] install every time as part of their build process. Since dependencies don't change often, this often means slower build times. npm-cache helps alleviate this problem by caching previously installed dependencies on the build machine.

Note: PAT Supported only on Azure Pipelines and TFS 2017 and newer. After you choose PAT, paste the PAT token you created into the command prompt window. Use a personal access token (PAT) if your Azure DevOps Server or TFS instance and the agent machine are not in a trusted domain. PAT authentication is handled by your Azure DevOps Server or TFS instance instead of the domain controller.

(Get PAT, run config)

Step 1: Kubectl create

You can add a service account to Tiller using the --service-account flag while you’re configuring Helm (step 2 below). As a prerequisite, you’ll have to create a role binding which specifies a role and a service account name that have been set up in advance.

Example: Service account with cluster-admin role

$ kubectl create -f rbac-config.yaml

serviceaccount "tiller" created

clusterrolebinding "tiller" created

$ helm init --service-account tiller

Step 2: helm init

To deploy a basic Tiller into an AKS cluster, use the helm init command.

To ensure that your Azure Web App named az400-38443478-main supports rolling upgrades and only 10 percent of users connect to the updated version of the app, you can use deployment slots with the following steps:

Create a Deployment Slot:

Navigate to the Azure Portal.

Go to your Web App az400-38443478-main.

Select Deployment slots in the menu.

Click on Add Slot.

Name the slot (e.g., staging) and if needed, clone settings from the production slot.

Configure the Traffic Percentage:

In the Deployment Slots menu, you will see a column for Traffic %.

Set the traffic percentage to 10% for the staging slot1.

This will route only 10% of the traffic to the updated version of the app in the staging slot.

Deploy the Updated App to the Staging Slot:

Deploy your updated application to the staging slot.

Test the application in the staging slot to ensure it’s working as expected.

Complete the Rolling Upgrade:

Once you’re satisfied with the performance and stability of the app in the staging slot, you can gradually increase the percentage of traffic until you’re ready to swap with the production slot.

To swap slots, go to the Deployment slots menu and click on Swap with the production slot.

By using deployment slots, you can achieve rolling upgrades with minimal administrative effort, as it allows you to test the new version on a subset of users before fully releasing it. Remember to adjust the traffic percentage and monitor the application’s performance throughout the process.

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

using Azure.Identity;

using Azure.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 needing to 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.

```mermaid

sequenceDiagram

participant Client

participant Server

Client->>Server: SYN

Server-->>Client: SYN-ACK

Client->>Server: ACK

Add the Diagram to the Wiki:

Replace the sample Mermaid syntax with the TCP handshake diagram syntax in the wiki page.

Save the Page:

Click on Save to save your changes.

By following these steps, you will have created a project wiki named Wiki1 and used Mermaid syntax to render a diagram

To prepare a Network Security Group (NSG) named az400-38443478-nsg1 for 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 to Network Security Groups and click on + Create.

Fill in the details, including the name az400-38443478-nsg1, and create the NSG.

Configure Outbound Security Rules:

Once the NSG is created, go to its settings.

Navigate to Outbound security rules.

Click on + Add to create a new rule.

Set the Destination port ranges to 443, which is the required port for Azure DevOps12.

Set the Protocol to TCP.

Set the Action to Allow.

Assign a Priority number (e.g., 100) that does not conflict with existing rules.

Provide a meaningful Name for the rule (e.g., AllowAzureDevOps).

Configure Default Rules to Deny All Other Traffic:

In the same Outbound security rules section, edit the default rule to deny all traffic.

Change the Action to Deny for 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 NSG with 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.

To configure a virtual machine template in your DevTest Labs environment named az400-38443478-dtl1 with Windows Server 2016 Datacenter that includes the Selenium tool and the Google Chrome browser, follow these steps:

Create a Custom Image with Windows Server 2016 Datacenter:

In the Azure Portal, go to your DevTest Lab az400-38443478-dtl1.

Navigate to Configuration and policies > Custom images.

Use an existing VM or create a new one with Windows Server 2016 Datacenter.

After setting up the VM, capture it to create a custom image1.

Install Selenium and Google Chrome on the VM:

Connect to the VM via RDP.

Download and install the Selenium WebDriver for your preferred programming language from the official Selenium website2.

For Google Chrome, download the offline installer from the official website and install it on the VM3.

Generalize the VM:

Run the sysprep command to generalize the VM, which prepares it to be used as a template.

Shut down the VM after sysprep completes.

Capture the Generalized VM to Create a Template:

In the Azure Portal, navigate to the VM and select Capture.

Provide the required details and create the image.

Add Selenium and Google Chrome Artifacts to the Template:

Go back to the DevTest Lab az400-38443478-dtl1.

Select Artifacts and add Selenium and Google Chrome artifacts to the template.

Ensure these artifacts are configured to install during the VM creation process.

Create VMs from the Template:

Now, when you create a new VM in the DevTest Lab, select the custom image you created.

The VM will be provisioned with Windows Server 2016 Datacenter, and the Selenium tool and Google Chrome browser will be installed automatically.

By following these steps, you can ensure that all virtual machines created from this template in your DevTest Lab will have the required operating system, tools, and browser installed. Remember to replace placeholder names with the actual names of your resources where necessary.

Batching CI runs

If you have many team members uploading changes often, you may want to reduce the number of runs you start. If you set batch to true, when a pipeline is running, the system waits until the run is completed, then starts another run with all changes that have not yet been built.

Example:

# specific branch build with batching

trigger:

batch: true

branches:

include:

- master

To clarify this example, let us say that a push A to master caused the above pipeline to run. While that pipeline is running, additional pushes B and C occur into the repository. These updates do not start new independent runs immediately. But after the first run is completed, all pushes until that point of time are batched together and a new run is started.

The commit-msg hook is invoked by git-commit and git-merge, and can be bypassed with the --no-verify option.

Box 1: A source control system

A source control system, also called a version control system, allows developers to collaborate on code and track changes. Source control is an essential tool for multi-developer projects.

Box 2: A hosted service

To build and deploy Xcode apps or Xamarin.iOS projects, you'll need at least one macOS agent. If your pipelines are in Azure Pipelines and a Microsoft-hosted agent meets your needs, you can skip setting up a self-hosted macOS agent.

Scenario: The investment planning applications suite will include one multi-tier web application and two iOS mobile applications. One mobile application will be used by employees; the other will be used by customers.

References:

Scenario: A branching strategy that supports developing new functionality in isolation must be used.

Feature isolation is a special derivation of the development isolation, allowing you to branch one or more feature branches from main, as shown, or from your dev branches.

When you need to work on a particular feature, it might be a good idea to create a feature branch.

Unattended config:

The agent can be set up from a script with no human intervention. You must pass --unattended and the answers to all questions.

To configure an agent, it must know the URL to your organization or collection and credentials of someone authorized to set up agents. All other responses are optional.

Change the ConfigurationMode parameter from ApplyOnly to ApplyAndAutocorrect.

The Register-AzureRmAutomationDscNode cmdlet registers an Azure virtual machine as an APS Desired State Configuration (DSC) node in an Azure Automation account.

Scenario: Current Technical Issue

The test servers are configured correctly when first deployed, but they experience configuration drift over time. Azure Automation State Configuration fails to correct the configurations.

Azure Automation State Configuration nodes are registered by using the following command.
