By following these steps, you will have successfully initialized the main branch, created a new branch named azure-pipelines, and set up a new Azure Pipelines YAML pipeline using the ASP.NET template

To configure a virtual machine template in your DevTest Labs environment namedaz400-38443478-dtl1with Windows Server 2016 Datacenter that includes the Selenium tooland the Google Chrome browser, follow these steps:

Create a Custom Image with Windows Server 2016 Datacenter:

In the Azure Portal, go to your DevTest Labaz400-38443478-dtl1.

Navigate toConfiguration 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 thesysprepcommand to generalize the VM, which prepares it to be used as a template.

Shutdown the VM aftersysprepcompletes.

Capture the Generalized VM to Create a Template:

In the Azure Portal, navigate to the VM and selectCapture.

Provide the required details and create the image.

Add Selenium and Google Chrome Artifacts to the Template:

Go back to the DevTest Labaz400-38443478-dtl1.

SelectArtifactsand 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 youcreate 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.

Task 11: Create an Artifact Feed with Specific Retention Policies

Step 1: Navigate to Artifacts

In your Azure DevOps Project (Project1), click on the Artifacts section in the left menu.

Step 2: Create a New Feed

Click on the + New feed button.

In the Name field, enter:

nginx

Copy

artifact_feed

Choose the visibility of the feed:

Project scoped (only accessible to Project1).

Or Organization scoped (accessible across your Azure DevOps organization).

Leave other settings at default unless you have specific permissions or upstream sources.

Click Create.

This creates a new feed named artifact_feed.

Step 3: Configure Retention Policies

In the Artifacts section, click on the feed named artifact_feed to open its details page.

In the top-right corner, click on the three dots (...) and select Feed settings.

Step 4: Set the Maximum Number of Versions to Retain

In the Feed settings page, find the Retention policies section.

Set Maximum number of versions per package to:

Copy

10

Click Save.

This ensures that only the latest 10 versions of any package are retained in the feed.

Step 5: Set the Downloaded Package Retention Period

In the Feed settings page, under Retention policies, find Downloaded package retention.

Set Number of days to retain downloaded packages to:

Copy

90

Click Save.

This ensures that downloaded packages will be retained in the cache for 90 days before deletion.

Use two linked templates, instead of the nested template.

You can use the Azure DevTest Labs Tasksextension that's installed in Azure DevOps to easily integrate your CI/CD build-and-release pipeline with Azure DevTest Labs. The extension installs three tasks:

Create a VM

Create a custom image from a VM

Delete a VM

The process makes it easy to, for example, quickly deploy a "golden image" for a specific test task and then delete it when the test is finished.

https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions

"We strongly recommend that you include the version of the action you are using by specifying a Git ref, SHA, or Docker tag. If you don't specify a version, it could break your workflows or cause unexpected behavior when the action owner publishes an update. Using the commit SHA of a released action version is the safest for stability and security. Ifthe action publishes major version tags, you should expect to receive critical fixes and security patches while still retaining compatibility. Note that this behavior is at the discretion of the action's author. Using the default branch of an action may beconvenient, but if someone releases a new major version with a breaking change, your workflow could break."

Box 1: ABuild task

Trigger a build

You have a Java code provisioned by the Azure DevOps demo generator. You will use WhiteSource Bolt extension to check the vulnerable components present in this code.

Go to Builds section under Pipelines tab, select the build definition WhiteSourceBolt and click on Queue to trigger a build.

To view the build in progress status, click on ellipsis and select View build results.

Box 2: WhiteSource Bolt

WhiteSource is the leader in continuous open source software security andcompliance management. WhiteSource integrates into your build process, irrespective of your programming languages, build tools, or development environments. It works automatically, continuously, and silently in the background, checking the security, licensing, and quality of your open source components against WhiteSource constantly-updated definitive database of open source repositories.

Box 1: microsoft.com/dotnet/sdk:2.3

The first group of lines declares from which base image we will use to build our container ontop of. If the local system does not have this image already, then docker will automatically tryand fetch it. The mcr.microsoft.com/dotnet/core/sdk:2.1 comes packaged with the .NET core 2.1 SDK installed, so it's up to the task of building ASP .NET core projects targeting version 2.1

Box 2: dotnet restore

The next instruction changes the working directory in our container to be /app, so all commands following this one execute under this context.

COPY *.csproj ./

RUN dotnet restore

Box 3: microsoft.com/dotnet/2.2-aspnetcore-runtime

When building container images, it's good practice to include only the production payload and its dependencies in the container image. We don't want the .NET core SDK included in our final image because we only need the .NET core runtime, so the dockerfile is written to use a temporary container that is packaged with the SDK called build-env to build the app.
