+# GitHub Copilot Instructions for Actions Runner Images Repository
+
+## Scope and goals
+
+- This repository serves as the source for building GitHub Actions runner and Azure DevOps agent images for Windows, Ubuntu, and macOS. You can find exact versions in the [Available Images](../README.md#available-images) section of README.md. Windows and Ubuntu images build on Azure infrastructure using Packer; macOS images use Anka virtualization.
+- Emphasize best practices for contributing to open-source projects, including code style, commit messages, and pull request etiquette.
+- Prefer clarity and correctness over creativity. If information is missing, ask clarifying questions or insert TODOs instead of guessing.
+
+## Code and command instructions
+
+- Follow the code style guide in [CONTRIBUTING.md](../CONTRIBUTING.md#code-style-guide) for Bash and PowerShell scripts, including naming conventions, file structure, and indentation rules.
+- Focus on re-using helpers when writing scripts. Windows, Linux and Ubuntu scripts have helper functions available to simplify installation and validation.
+- Always confirm versions and installation paths against existing toolset files and installation scripts.
+
+## Output format
+
+- Use GitHub Flavored Markdown only. Avoid raw HTML unless necessary.
+- One H1 (`#`) per page, followed by logical, sequential headings (`##`, `###`, …).
+- Use fenced code blocks with language identifiers (` ```bash `, ` ```json `, ` ```yaml `, etc.).
+- Use blockquote callouts for notes:
+  > [!NOTE] Context or nuance  
+  > [!TIP] Helpful hint  
+  > [!WARNING] Risks or breaking changes  
+  > [!IMPORTANT] Critical requirement for functionality
+
+## Style and tone
+
+- Audience: Open-source contributors, GitHub Actions maintainers, and developers building custom runner images. Assume familiarity with CI/CD concepts, Packer, and basic infrastructure provisioning, but explain platform-specific details (Azure for Windows/Ubuntu, Anka for macOS) when relevant.
+- Voice: Second person ("you"), active voice, imperative for operational steps.
+- Be concise: short paragraphs and sentences. Prefer lists and step-by-steps, especially for operational procedures and troubleshooting.
+- Use inclusive, accessible language. Avoid idioms, sarcasm, and culturally specific references.
+- English: en-US (spelling, punctuation, and units).
+
+## Safety and integrity
+
+- Do not expose sensitive credentials (API tokens, Azure subscription IDs, etc.) in code examples.
+- Do not fabricate tool versions, installation paths, or software availability without verifying against toolset files or actual installation scripts.
+- Always call out assumptions and limitations explicitly, especially for changes affecting runner image behavior or software availability.
+- If ambiguous requests are made about image modifications, ask clarifying questions about target OS, tool versions, and compatibility requirements before proceeding.

+
+## Adding a new tool to an image
+
+### General rules
+
+- For every new tool, add validation scripts and update the software report script to ensure that it is included in the documentation.
+- If the tool is available on multiple platforms (macOS, Windows, Linux), make sure you include it on as many as possible.
+- If installing multiple versions of the tool, consider putting the list of versions in the corresponding `toolset.json` file. This will help other customers configure their builds flexibly. See [toolset-windows-2019.json](images/windows/toolsets/toolset-2019.json) as an example.
+- Use consistent naming across all files.
+- Validation scripts should be simple and shouldn't change the image content.
+
+### Windows
+
+- Add a script that will install the tool and put the script in the `scripts/build` folder.
+There are a bunch of helper functions that could simplify your code: `Install-ChocoPackage`, `Install-Binary`, `Install-VSIXFromFile`, `Install-VSIXFromUrl`, `Invoke-DownloadWithRetry`, `Test-IsWin19`, `Test-IsWin22` (find the full list of helpers in [ImageHelpers.psm1](images/windows/scripts/helpers/ImageHelpers.psm1)).
+- Add a script that will validate the tool installation and put the script in the `scripts/tests` folder.
+We use [Pester v5](https://github.com/pester/pester) for validation scripts. If the tests for the tool are complex enough, create a separate `*.Tests.ps1`. Otherwise, use `Tools.Tests.ps1` for simple tests.
+Add `Invoke-PesterTests -TestFile <testFileName> [-TestName <describeName>]` at the end of the installation script to ensure that your tests will be run.
+- Add changes to the software report generator `images/windows/scripts/docs-gen/Generate-SoftwareReport.ps1`. The software report generator is used to generate an image's README file, e.g. [Windows2019-Readme.md](images/windows/Windows2019-Readme.md) and uses [MarkdownPS](https://github.com/Sarafian/MarkdownPS).
+
+### Ubuntu
+
+- Add a script that will install and validate the tool and put the script in the `scripts/build` folder.
+Use existing scripts such as [github-cli.sh](images/ubuntu/scripts/build/github-cli.sh) as a starting point.
+  - Use [helpers](images/ubuntu/scripts/helpers/install.sh) to simplify the installation process.
+  - The validation part should `exit 1` if there is any issue with the installation.
+- Add changes to the software report generator `images/ubuntu/scripts/docs-gen/Generate-SoftwareReport.ps1`. The software report generator is used to generate an image's README file, e.g. [Ubuntu2204-Readme.md](images/ubuntu/Ubuntu2204-Readme.md)   and it uses [MarkdownPS](https://github.com/Sarafian/MarkdownPS).
+
+### macOS
+
+The macOS source lives in this repository and is available for everyone. However, the macOS image-generation CI doesn't support external contributions yet, so we are not able to accept pull requests for now.
+We are in the process of preparing the macOS CI to accept contributions. Until then, we appreciate your patience and ask that you continue to make tool requests by filing issues.
+
+## Code style guide
+
+The principles of clean code apply to all languages. The main points are:
+
+- Use meaningful names for variables, functions, files, etc.
+- Keep functions short and simple.
+- Use comments to explain what the code does.
+- Use a consistent code style, naming convention, and file structure.
+
+### File structure
+
+- Each file should have a header with a title and a short description of the file.
+- Each file should have a newline at the end.
+- Use blank lines to separate logical blocks of code, but don't abuse blank lines:
+  - Don't add a blank line in the beginning and end of a block or function.
+  - Don't add blank lines between logically connected statements.
+- Avoid trailing whitespace.
+
+### Bash scripts
+
+#### Naming convention for bash scripts
+
+- Use lowercase letters for variable names.
+- Use uppercase letters for constants.
+- Use underscores to separate words in variable names.
+
+#### Bash script structure
+
+Each script should start with the following shebang:
+
+```bash
+#!/bin/bash -e
+```
+
+> TODO: do we need to set pipefail?
+
+This will make the script exit if any command fails.
+
+After the shebang, add a header with the following format:
+
+```bash
+################################################################################
+##  File:  <filename>
+##  Desc:  <short description of what the script does>
+################################################################################
+```
+
+Then import helpers that are used in the script.
+
+For Linux:
+
+```bash
+source $HELPER_SCRIPTS/os.sh
+source $HELPER_SCRIPTS/install.sh
+source $HELPER_SCRIPTS/etc-environment.sh
+```
+
+For macOS:
+
+```bash
+source ~/utils/utils.sh
+```
+
+> [!NOTE]
+> You don't need to import all helpers, only the ones that are used in the script.
+
+After that, add the script code.
+
+### Indentations and line breaks in bash scripts
+
+- Use 4 spaces for indentation.
+- Use 1 space between `if`/`for`/`while` and `[[` and between `[[` and the condition.
+- Place `then`/`do` on the new line.
+- For short `if`/`for`/`while` statements, use the one-line format.
+- Break long pipelines using `\`.
+
+### Other recommendations for bash scripts
+
+- For command substitution, use `$()` instead of backticks.
+- Use `[[` instead of `[` for conditional expressions.
+- Prefer using long options instead of short keys, but there are exceptions, e.g.:
+  - `tar -xzf`
+  - `apt-get -yqq`
+  - `curl -sSLf`
+  - `wget -qO-`
+
+### PowerShell scripts
+
+#### Naming convention for PowerShell scripts
+
+- Use camelCase for variable names.
+- Use uppercase letters for constants.
+- Use `Verb-Noun` and PascalCase for function names.
+
+### PowerShell script structure
+
+Each script should start with the following header:
+
+```powershell
+################################################################################
+##  File:  <filename>
+##  Desc:  <short description of what the script does>
+################################################################################
+```
+
+Then declare functions that are used in the script.
+
+> TODO: do we need to set the error action preference and progress preference?
+>
+> ```powershell
+> $ErrorActionPreference = "Stop"
+> $ProgressPreference = "SilentlyContinue"
+> ```
+
+For Linux and macOS, import helpers that are used in the script:
+
+For Linux:
+
+```powershell
+Import-Module "$env:HELPER_SCRIPTS/Tests.Helpers.psm1" -DisableNameChecking
+```
+
+For macOS:
+
+```powershell
+Import-Module "$env:HOME/image-generation/helpers/Common.Helpers.psm1"
+Import-Module "$env:HOME/image-generation/helpers/Xcode.Helpers.psm1" -DisableNameChecking
+```
+
+> [!NOTE]
+> You don't need to import all helpers, only the ones that are used in the script.
+
+After that, add the script code.
+
+### Indentations and line breaks in PowerShell scripts
+
+- Use 4 spaces for indentation.
+- Use 1 space between `if`/`elseif`/`foreach` and `(` but not between `(` and the condition.
+- Add a space before and after pipe `|` and redirection `>` operators.
+- Align properties in hash tables.
+- Use [1TBS](https://en.wikipedia.org/wiki/Indentation_style#Variant:_1TBS_(OTBS)) style for curly braces:
+  - If block of statement is long, then place it on the new line, indent it, and add a closing curly brace on the new line.
+  - If block of statement is short, then place it on the same line as the statement.
+
+  ```powershell
+  function Show-Example1 {
+      $exampleVariable = Get-ChildItem $env:TEMP
+      $exampleVariable | ForEach-Object {
+          $itemName = $_.Name
+          $itemPath = $_.FullName
+      }
+  }
+
+  $Example2 | Some-Function -Arguments @{Parameter1 = "Disabled"}
+  ```
+
+- Avoid using aliases.
+- Break long pipelines using backticks or use [splatting](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_splatting?view=powershell-7.3):
+
+  ```powershell
+  # Instead of this
+  Copy-Item -Path "test.txt" -Destination "test2.txt" -WhatIf
+
+  # you can use this
+  $HashArguments = @{
+    Path = "test.txt"
+    Destination = "test2.txt"
+    WhatIf = $true
+  }
+  Copy-Item @HashArguments
+  ```
+
+  When using backticks be extra careful with trailing whitespace as they can cause errors.
+
+### Other recommendations for PowerShell scripts
+
+- Verify exit codes of commands.
+- When writing a function, provide a docstring that describes what the function does.

-# GitHub Actions Virtual Environments
-This repository contains the source used to create the [virtual environments](https://help.github.com/en/actions/reference/virtual-environments-for-github-hosted-runners) for GitHub Actions hosted runners, as well as the VM images of [Microsoft-hosted agents](https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=azure-devops#use-a-microsoft-hosted-agent) used for Azure Pipelines. To file bug reports, or request that tools be added/updated, please [open an issue using the appropriate template](https://github.com/actions/virtual-environments/issues/new/choose). To build a VM machine from this repo's source, see the [instructions](./help/CreateImageAndAzureResources.md).
-
-For general questions about using the virtual environments or writing your Actions workflow, please open requests in the [GitHub Actions Community Forum](https://github.community/c/github-actions/41).

-```
-The Ubuntu 20.04 virtual environment is currently provided as a preview only.
-The "ubuntu-latest" YAML workflow label still uses the Ubuntu 18.04 virtual environment.
-```
-
-***Looking for other Linux distributions?*** We do not plan to offer other Linux distributions. We recommend using Docker if you'd like to build using other distributions with the hosted virtual environments. Alternatively, you can leverage [self-hosted runners] and fully customize your environment to your needs.
-
-***Where is the macOS source?*** We are in the process of preparing our macOS source to live in this repo so we can take contributions from the community. Until then, we appreciate your patience and ask you continue to make tool requests by filing issues.
-
-## Software Guidelines
-In general, these are the guidelines we consider when deciding what to pre-install:
-
- Tools and ecosystems that are broadly popular and widely-used will be given priority.
- Recent versions of tools will be given priority over older versions.
- Tools and versions that are deprecated or have reached end-of-life will not be added.
- Tools and versions will typically be removed 6 months after they are deprecated or have reached end-of-life.
- If a tool can be installed during the build, we will evaluate how much time is saved
- and how much space is used by having the tool pre-installed.
- MIT, Apache, and GNU licenses are ok, anything else we'll have to check with lawyers.
- If a tool takes much space we will evaluate space usage and provide a decision if this tool can be pre-installed.
- If a tool requires the support of more than one version, we will consider the cost of this maintenance, how often new versions bring dangerous updates.
-
-**Note:** For new tools, please, create an issue and get an approval from us to add this tool to the image before creating the pull request.
-
-## Updates to virtual environments
-*Cadence*
-
-We typically deploy weekly updates to the software on the virtual environments.
-For some tools, we always install the latest at the time of the deployment; for others,
-we pin the tool to specific version(s).
-
-*Following Along / Change Notifications*
-
-* **High Impact Changes** (ex. breaking changes, new or deprecated environments) will be posted to the GitHub Changelog on our [blog](https://github.blog/changelog/) and on [twitter](https://twitter.com/GHchangelog).  
-Low Impact changes will be pinned in this repository and marked with the [Announcement](https://github.com/actions/virtual-environments/labels/Announcement) label.
-* **Regular Weekly Rhythm** can be followed by watching [Releases](https://github.com/actions/virtual-environments/releases) to see when we generate candidate environments or deploy new ones. You can also track upcoming changes using the [awaiting-deployment](https://github.com/actions/virtual-environments/labels/awaiting-deployment) label.

+## Announcements
+
+See notable upcoming changes by viewing issues with the [Announcement](https://github.com/actions/runner-images/labels/Announcement) label.
+
+## Image Definitions
+
+### Beta
+
+The purpose of a Beta is to collect feedback on an image before it is released to GA. The goal of a Beta is to identify and fix any potential issues that exist on that
+image. Images are updated on a weekly cadence. Any workflows that run on a beta image do not fall under the customer [SLA](https://github.com/customer-terms/github-online-services-sla) in place for Actions.
+Customers choosing to use Beta images are encouraged to provide feedback in the runner-images repo by creating an issue. A Beta may take on different availability, i.e. public vs private.
+
+### GA
+
+A GA (General Availability) image has been through a Beta period and is deemed ready for general use. Images are updated on a weekly cadence. In order to be moved to
+GA the image must meet the following criteria:
+
+1. Has been through a Beta period (public or private)
+2. Most major software we install on the image has a compatible
+version for the underlying OS and
+3. All major bugs reported during the Beta period have been addressed.
+
+This image type falls under the customer [SLA](https://github.com/customer-terms/github-online-services-sla) for actions. GA images are eventually deprecated according to our guidelines as we only support the
+latest 2 versions of an OS.
+
+#### Latest Migration Process
+
+GitHub Actions and Azure DevOps use the `-latest` YAML label (ex: `ubuntu-latest`, `windows-latest`, and `macos-latest`). These labels point towards the newest stable OS version available.
+
+
+The `-latest` migration process is gradual and happens over 1-2 months in order to allow customers to adapt their workflows to the newest OS version. During this process, any workflow using the `-latest` label, may see changes in the OS version in their workflows or pipelines. To avoid unwanted migration, users can specify a specific OS version in the yaml file (ex: macos-14, windows-2022, ubuntu-22.04).

+- We typically deploy weekly updates to the software on the runner images.
+
+## Software and Image Support
+
+### Support Policy
+
+- Tools and versions will typically be removed 6 months after they are deprecated or have reached end-of-life
+- We support (at maximum) 2 GA images and 1 beta image at a time. We begin the deprecation process of the oldest image label once the newest OS image label has been released to GA.
+- The images generally contain the latest versions of packages installed except for Ubuntu LTS where we mostly rely on the Canonical-provided repositories.
+
+- Popular tools can have several versions installed side-by-side with the following strategy:
+
+| Tool name | Installation strategy |
+|-----------|-----------------------|
+| Docker images | not more than 3 latest LTS OS\tool versions. New images or new versions of current images are added using the standard tool request process |
+| Java      | all LTS versions |
+| Node.js   | 3 latest LTS versions |
+| Go        | 3 latest minor versions |
+| Python <br/> Ruby | 5 most popular `major.minor` versions |
+| PyPy      | 3 most popular `major.minor` versions |
+| .NET Core | 2 latest LTS versions and 1 latest version. For each feature version only latest patch is installed. Note for [Ubuntu images see details.](./docs/dotnet-ubuntu.md) |
+| GCC <br/> GNU Fortran <br/> Clang <br/> GNU C++ | 3 latest major versions |
+| Android NDK | 1 latest non-LTS, 2 latest LTS versions |
+| Xcode     | - only one major version of Xcode will be supported per macOS version <br/> - all minor versions of the supported major version will be available <br/> - beta and RC versions will be provided "as-is" in the latest available macOS image only no matter of beta/GA status of the image <br/> - when a new patch version is released, the previous patch version will be replaced |
+| Xcode Platforms | - only three major.minor versions of platform tools and simulator runtimes will be available for installed Xcode, including beta/RC versions |
+
+### Package managers usage
+
+We use third-party package managers to install software during the image generation process. The table below lists the package managers and the software installed.
+> [!NOTE]
+> Third-party repositories are re-evaluated every year to identify if they are still useful and secure.
+
+| Operating system | Package manager                       | Third-party repos and packages |
+| :---             |        :---:                          |                           ---: |

+
+### Image Deprecation Policy
+
+- Images begin the deprecation process of the oldest image label once a new GA OS version has been released.
+- Deprecation process begins with an announcement that sets a date for deprecation
+- As it gets closer to the date, GitHub begins doing scheduled brownouts of the image
+- During this time there will be an Announcement pinned in the repo to remind users of the deprecation.
+- Finally GitHub will deprecate the image and it will no longer be available
+
+### Preinstallation Policy
+
+In general, these are the guidelines we follow when deciding what to pre-install on our images:
+
+- Popularity: widely-used tools and ecosystems will be given priority.
+- Latest Technology: recent versions of tools will be given priority.
+- Deprecation: end-of-life tools and versions will not be added.
+- Licensing: MIT, Apache, or GNU licenses are allowed.
+- Time & Space on the Image: we will evaluate how much time is saved and how much space is used by having the tool pre-installed.
+- Support: If a tool requires the support of more than one version, we will consider the cost of this maintenance.
+
+### Default Version Update Policy
+
+- In general, once a new version is installed on the image, we announce the default version update 2 weeks prior to deploying it.
+- For potentially dangerous updates, we may extend the timeline up to 1 month between the announcement and deployment.
+
+## How to Interact with the Repo
+
+- **Issues**: To file a bug report, or request tools to be added/updated, please [open an issue using the appropriate template](https://github.com/actions/runner-images/issues/new/choose)
+- **Discussions**: If you want to share your thoughts about image configuration, installed software, or bring a new idea, please create a new topic in a [discussion](https://github.com/actions/runner-images/discussions) for a corresponding category. Before making a new discussion please make sure no similar topics were created earlier.
+- For general questions about using the runner images or writing your Actions workflow, please open requests in the [GitHub Actions Community Forum](https://github.community/c/github-actions/41).

+## FAQs
+
+<details>
+   <summary><b><i>What images are available for GitHub Actions and Azure DevOps?</b></i></summary>
+
+The availability of images for GitHub Actions and Azure DevOps is the same. However, deprecation policies may differ. See documentation for more details:
+- [GitHub Actions](https://docs.github.com/en/free-pro-team@latest/actions/reference/specifications-for-github-hosted-runners#supported-runners-and-hardware-resources)
+- [Azure DevOps](https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=azure-devops&tabs=yaml#software)
+</details>
+
+<details>
+   <summary><b><i>What image version is used in my build?</b></i></summary>
+
+Usually, image deployment takes 2-3 days, and documentation in the `main` branch is only updated when deployment is finished. To find out which image version and what software versions are used in a specific build, see `Set up job` (GitHub Actions) or `Initialize job` (Azure DevOps) step log.

+
+<details>
+   <summary><b><i>Looking for other Linux distributions?</b></i></summary>
+
+We do not plan to offer other Linux distributions. We recommend using Docker if you'd like to build using other distributions with the hosted runner images. Alternatively, you can leverage [self-hosted runners] and fully customize your VM image to your needs.
+</details>
+
+<details>
+   <summary><b><i>How do I contribute to the macOS source?</b></i></summary>
+
+macOS source lives in this repository and is available for everyone. However, macOS image-generation CI doesn't support external contributions yet so we are not able to accept pull-requests for now.
+
+We are in the process of preparing macOS CI to accept contributions. Until then, we appreciate your patience and ask you to continue to make tool requests by filing issues.
+</details>
+
+<details>
+   <summary><b><i>How does GitHub determine what tools are installed on the images?</b></i></summary>
+
+For some tools, we always install the latest at the time of the deployment; for others, we pin the tool to specific version(s). For more details please see the [Preinstallation Policy](#preinstallation-policy)
+</details>
+
+<details>
+   <summary><b><i>How do I request that a new tool be pre-installed on the image?</b></i></summary>
+Please create an issue and get an approval from us to add this tool to the image before creating the pull request.
+</details>
+
+<details>
+   <summary><b><i>What branch should I use to build custom image?</b></i></summary>
+We strongly encourage customers to build their own images using the main branch.
+This repository contains multiple branches and releases that serve as document milestones to reflect what software is installed in the images at certain point of time. Current builds are not idempotent and if one tries to build a runner image using the specific tag it is not guaranteed that the build will succeed.

+# GitHub Actions Runner Images
+
+The runner-images project uses [Packer](https://www.packer.io/) to generate disk images for Windows 2019/2022 and Ubuntu 22.04/24.04.
+
+Each image is configured by a HCL2 Packer template that specifies where to build the image (Azure, in this case),
+and what steps to run to install software and prepare the disk.
+
+The Packer process initializes a connection to the Azure subscription using Azure CLI and creates temporary resources
+required for the build process: a resource group, network interfaces and a virtual machine from the "clean" image specified in the template.
+
+If the VM deployment succeeds, Packer connects to it using SSH or WinRM and begins executing installation steps from the template one-by-one.
+If any step fails, image generation is aborted, and the temporary VM is terminated.
+Packer also attempts to clean up all the temporary resources it created (unless otherwise configured).
+
+After successful completion of all installation steps, Packer creates a managed image from the temporary VM's disk and deletes the VM.

+The build agent is a machine where the Packer process will be started.
+You can use any physical or virtual machine running Windows or Linux OS.
+Of course, you may also use an [Azure VM](https://docs.microsoft.com/en-us/azure/virtual-machines/windows/quick-create-cli).
+In any case, you will need these software installed:
+
+- Packer 1.8.2 or higher.
+
+  Download and install it manually from [here](https://www.packer.io/downloads) or use [Chocolatey](https://chocolatey.org/):
+
+  ```powershell
+  choco install packer
+  ```
+
+- Git.
+
+  For Linux - install the latest version from your distro's package repo.
+
+  For Windows - download and install it from [here](https://gitforwindows.org/) or use [Chocolatey](https://chocolatey.org/):
+
+  ```powershell
+  choco install git -params '"/GitAndUnixToolsOnPath"'
+  ```
+
+- Powershell 5.0 or higher.
+
+  In Windows you already have it.
+
+  For Linux follow instructions [here](https://learn.microsoft.com/en-us/windows-server/administration/linux-package-repository-for-microsoft-software)
+  to add Microsoft's Linux Software Repository and then install the `powershell` package.
+
+- Azure CLI.
+
+  Follow the instructions [here](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli).
+  Or if you use Windows, you may run this command in Powershell instead:
+
+  ```powershell
+  Invoke-WebRequest -Uri https://aka.ms/installazurecliwindows -OutFile .\AzureCLI.msi
+  Start-Process msiexec.exe -Wait -ArgumentList '/I AzureCLI.msi /quiet'; rm .\AzureCLI.msi
+  ```
+
+## Manual image generation
+
+This repository includes a script that assists in generating images in Azure.
+All you need is an Azure subscription, a resource group in that subscription and a build agent configured as described above.
+
+All the commands below should be executed in PowerShell.
+
+First, clone the runner-images repository and set the current directory to it:
+
+```powershell
+git clone https://github.com/actions/runner-images.git
+Set-Location runner-images
+```
+
+Then, import the [GenerateResourcesAndImage](../helpers/GenerateResourcesAndImage.ps1) script from the `helpers` subdirectory:
+
+```powershell
+Import-Module .\helpers\GenerateResourcesAndImage.ps1
+```
+
+Finally, run the `GenerateResourcesAndImage` function, setting the mandatory arguments: image type and where to build and store the resulting managed image:
+
+- `SubscriptionId` - your Azure Subscription ID;
+- `ResourceGroupName` - the name of the resource group that will store the resulting artifact (e.g., "imagegen-test").
+    The resource group must already exist in your Azure subscription;
+- `AzureLocation` - the location where resources will be created (e.g., "East US");
+- `ImageType` - the type of image to build (valid options are "Windows2019", "Windows2022", "Windows2025", "Ubuntu2204", "Ubuntu2404").
+
+This function automatically creates all required Azure resources and initiates the Packer image generation for the selected image type.
+
+When the image is ready, you may proceed to [deployment](#generated-machine-deployment).
+
+## Manual Image Generation Customization
+
+The `GenerateResourcesAndImage` function accepts a number of arguments that may assist you in generating an image in your specific environment.
+
+For example, you may want all the resources involved in the image generation process to be tagged.
+In this case, pass a HashTable of tags as a value for the `Tags` parameter.
+
+If you don't want the function to authenticate interactively, you should create a Service Principal and invoke the function with the parameters `AzureClientId`, `AzureClientSecret` and `AzureTenantId`.
+You can find more details in the [corresponding section below](#azure-subscription-authentication).
+
+Use `get-help GenerateResourcesAndImage -Detailed` for the complete list of available parameters.
+
+### Network Security
+
+To connect to a temporary virtual machine, Packer uses WinRM or SSH.
+
+If your build agent is located outside of the Azure subscription where the temporary VM is created, a public network interface and public IP address are used.
+Make sure that firewalls are configured properly and that WinRM (TCP port 5986) and SSH (TCP port 22) connections are allowed both outgoing for the build agent and incoming for the temporary VM.
+Also, if you don't want the temporary VM to be accessible from everywhere, set the `RestrictToAgentIpAddress` parameter value to `$true`
+to set up firewall rules allowing access only from your build agent's public IP address.
+
+If your build agent and temporary VM are in the same subscription, you can configure Packer to connect using a private virtual network.
+To achieve this, set proper values for the environment variables `VNET_RESOURCE_GROUP`, `VNET_NAME` and `VNET_SUBNET`.
+
+### Azure Subscription Authentication
+
+Packer uses a Service Principal to authenticate in Azure infrastructure.
+For more information about Service Principals, refer to the
+[Azure documentation](https://docs.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-portal).
+
+The `GenerateResourcesAndImage` function is able to create a Service Principal to be used by Packer.
+It uses the Connect-AzAccount cmdlet that invokes an interactive authentication process by default.
+If you don't want to use interactive authentication, you should create a Service Principal with full read-write permissions for the selected Azure subscription on your own
+and provide proper values for the parameters `AzureClientId`, `AzureClientSecret` and `AzureTenantId`.
+
+Here is an example of how to create a Service Principal using the Az PowerShell module:
+
+```powershell
+$credentials = [Microsoft.Azure.PowerShell.Cmdlets.Resources.MSGraph.Models.ApiV10.MicrosoftGraphPasswordCredential]@{
+  StartDateTime = Get-Date
+  EndDateTime = (Get-Date).AddDays(7)
+}
+
+$sp = New-AzADServicePrincipal -DisplayName "imagegen-app"
+$appCred = New-AzADAppCredential -ApplicationId $sp.AppId -PasswordCredentials $credentials
+
+Start-Sleep -Seconds 30
+New-AzRoleAssignment -RoleDefinitionName "Contributor" -PrincipalId $sp.Id
+Start-Sleep -Seconds 30
+
+@{
+  ClientId = $sp.AppId
+  ClientSecret = $appCred.SecretText
+  TenantId = (Get-AzSubscription -SubscriptionId $SubscriptionId).TenantId
+}
+```
+
+## Generated Machine Deployment
+
+After successful image generation, a Virtual Machine can be created from the generated image using the [CreateAzureVMFromPackerTemplate](../helpers/CreateAzureVMFromPackerTemplate.ps1) script.
+
+```powershell
+Import-Module .\helpers\CreateAzureVMFromPackerTemplate.ps1
+
+CreateAzureVMFromPackerTemplate -SubscriptionId {YourSubscriptionId} -ResourceGroupName {ResourceGroupName} -ManagedImageName "Runner-Image-Ubuntu2204" -VirtualMachineName "testvm1" -AdminUsername "shady1" -AdminPassword "SomeSecurePassword1" -AzureLocation "eastus"
+```
+
+Where:
+
+- `SubscriptionId` - the Azure subscription ID where resources will be created;
+- `ResourceGroupName` - the Azure resource group name where the Azure virtual machine will be created;
+- `ManagedImageName` - the name of the managed image to be used for the virtual machine creation;
+- `VirtualMachineName` - the name of the virtual machine to be generated;
+- `AdminUserName` - the administrator username for the virtual machine to be created;
+- `AdminPassword` - the administrator password for the virtual machine to be created;
+- `AzureLocation` - the location where the Azure virtual machine will be provisioned (e.g., "eastus").
+
+This function creates an Azure VM and generates network resources in Azure to make the VM accessible.
+
+## Automated image generation
+
+If you want to generate images automatically (e.g., as a part of a CI/CD pipeline),
+you can use Packer directly. To do this, you will need:
+
+- a build agent configured as described in the
+  [Build agent preparation](#build-agent-preparation) section;
+- an Azure subscription and Service Principal configured as described in the
+  [Azure subscription authentication](#azure-subscription-authentication) section;
+- a resource group created in your Azure subscription where the managed image will be stored;
+- a string to be used as a password for the user used to install software (Windows only).
+
+Then, you can invoke Packer in your CI/CD pipeline using the following commands:
+
+```powershell
+packer plugins install github.com/hashicorp/azure 2.2.1
+
+packer build -only "$BuildName*" `
+             -var "subscription_id=$SubscriptionId" `
+             -var "client_id=$ClientId" `
+             -var "client_secret=$ClientSecret" `
+             -var "install_password=$InstallPassword" `
+             -var "location=$Location" `
+             -var "image_os=$ImageOS" `
+             -var "managed_image_name=$ImageName" `
+             -var "managed_image_resource_group_name=$ImageResourceGroupName" `
+             -var "tenant_id=$TenantId" `
+             $TemplatePath
+```
+
+Where:
+
+- `BuildName` - name of the build defined in Packer template's `build{}` block (e.g. "ubuntu-24_04", "windows-2025");
+- `SubscriptionId` - your Azure Subscription ID;
+- `ClientId` and `ClientSecret` - Service Principal credentials;
+- `TenantId` - Azure Tenant ID;
+- `InstallPassword` - password for the user used to install software (Windows only);
+- `Location` - location where resources will be created (e.g., "East US");
+- `ImageOS` - the type of OS that will be deployed as a temporary VM (e.g. "ubuntu24", "win25");
+- `ImageName` and `ImageResourceGroupName` - name of the resource group where the managed image will be stored;
+- `TemplatePath` - path to the folder with Packer template files (e.g., "images/windows/templates").
+
+### Required variables
+
+The following variables are required to be passed to the Packer process:
+
+| Template var | Env var | Description
+| ------------ | ------- | -----------
+| `subscription_id` | `ARM_SUBSCRIPTION_ID` | The subscription under which the build will be performed.
+| `client_id` | `ARM_CLIENT_ID` | The Active Directory service principal associated with your builder.
+| `client_secret` | `ARM_CLIENT_SECRET` | The password or secret for your service principal; may be omitted if `client_cert_path` is set.
+| `client_cert_path` | `ARM_CLIENT_CERT_PATH` | The location of a PEM file containing a certificate and private key for the service principal; may be omitted if `client_secret` is set.
+| `location` | `ARM_RESOURCE_LOCATION` | The Azure datacenter in which your VM will be built.
+| `managed_image_resource_group_name` | `ARM_RESOURCE_GROUP` | The resource group under which the final artifact will be stored.
+
+### Optional variables
+
+The following variables are optional:
+
+- `managed_image_name` - the name of the managed image to create. If not specified, "Runner-Image-{{ImageType}}" will be used;
+- `build_resource_group_name` - specify an existing resource group to run the build in; by default, a temporary resource group will be created and destroyed as part of the build; if you do not have permission to do so, use `build_resource_group_name` to specify an existing resource group to run the build in;
+- `object_id` - the object ID for the AAD SP; will be derived from the oAuth token if empty;
+- `tenant_id` - the Active Directory tenant identifier with which your `client_id` and `subscription_id` are associated; if not specified, `tenant_id` will be looked up using `subscription_id`;
+- `temp_resource_group_name` - the name assigned to the temporary resource group created during the build; if this value is not set, a random value will be assigned; this resource group is deleted at the end of the build;
+- `private_virtual_network_with_public_ip` - this value allows you to set a `virtual_network_name` and obtain a public IP; if this value is not set and `virtual_network_name` is defined, Packer is only allowed to be executed from a host on the same subnet / virtual network;
+- `virtual_network_name` - use a pre-existing virtual network for the VM; this option enables private communication with the VM, no public IP address is used or provisioned (unless you set `private_virtual_network_with_public_ip`);
+- `virtual_network_resource_group_name` - if `virtual_network_name` is set, this value may also be set; if `virtual_network_name` is set, and this value is not set, the builder attempts to determine the resource group containing the virtual network; if the resource group cannot be found, or it cannot be disambiguated, this value should be set;
+- `virtual_network_subnet_name` - if `virtual_network_name` is set, this value may also be set; if `virtual_network_name` is set, and this value is not set, the builder attempts to determine the subnet to use with the virtual network; if the subnet cannot be found, or it cannot be disambiguated, this value should be set.
+
+## Builder variables
+
+The `builders` section contains variables for the `azure-arm` builder used in the project. Most of the builder variables are inherited from the `user variables` section, however, the variables can be overwritten to adjust image-generation performance.
+
+- `vm_size` - the size of the VM used for building; this can be changed when you deploy a VM from your image;
+- `image_os` - the type of OS that will be deployed as a temporary VM;
+- `image_version` - specify the version of an OS to boot from.
+
+**Detailed Azure builders documentation can be found in the [packer documentation](https://www.packer.io/docs/builders/azure).**
+
+## Toolset
+
+The configuration for some installed software is located in `toolset.json` files. These files define the list of Ruby, Python, Go versions, the list of PowerShell modules and VS components that will be installed on the image. They can be changed if these tools are not required, to reduce image generation time or image size.
+
+Generated tool versions and details can be found in related projects:
+
+- [Python](https://github.com/actions/python-versions/)
+- [Go](https://github.com/actions/go-versions)
+- [Node](https://github.com/actions/node-versions)
+
+## Post-generation scripts
+
+> :warning: These scripts are intended to be run on a VM deployed in Azure
+
+The user, created during the image generation, does not exist in the resulting image. Hence, some configuration files related to the user's home directory need to be changed, as well as the file permissions for some directories. Scripts for that are located in the `post-gen` folder in the repository:
+
+- Windows: <https://github.com/actions/runner-images/tree/main/images/windows/assets/post-gen>
+- Linux: <https://github.com/actions/runner-images/tree/main/images/ubuntu/assets/post-gen>
+
+**Note:** The default user for Linux should have `sudo privileges`.
+
+The scripts are copied to the image during the generation process to the following paths:
+
+- Windows: `C:\post-generation`
+- Linux:  `/opt/post-generation`
+
+### Running scripts
+
+- Ubuntu
+
+  ```bash
+  sudo su -c "find /opt/post-generation -mindepth 1 -maxdepth 1 -type f -name '*.sh' -exec bash {} \;"
+  ```
+
+- Windows
+
+  ```powershell
+  Get-ChildItem C:\post-generation -Filter *.ps1 | ForEach-Object { & $_.FullName }
+  ```
+
+### Script Details: Ubuntu
+
+- **cleanup-logs.sh** - removes all build process logs from the machine;
+- **environment-variables.sh** - replaces `$HOME` with the default user's home directory for environment variables related to the default user home directory;
+- **homebrew-permissions.sh** - resets the Homebrew repository directory by running `git reset --hard` to make the working tree clean after changing permissions in /home and changes the repository directory owner to the current user;
+- **rust-permissions.sh** - fixes permissions for the Rust folder; a detailed issue explanation is provided in [runner-images/issues/572](https://github.com/actions/runner-images/issues/572).
+
+### Script Details: Windows
+
+- **GenerateIISExpressCertificate.ps1** - generates and imports a certificate to run applications with IIS Express through HTTPS;
+- **InternetExplorerConfiguration.ps1** - turns off the Internet Explorer Enhanced Security feature;
+- **Msys2FirstLaunch.ps1** - initializes the bash user profile in MSYS2;
+- **VSConfiguration.ps1** - performs initial Visual Studio configuration.

+# Ubuntu .NET Core Versions
+
+.NET has changed the recommended install methods for Ubuntu from 2404.
+
+This document gives an overview of these change and the impact this has on the `runner-images`.
+
+## .NET Core for Ubuntu 2004 and 2204
+
+2004 and 2204 use the [Microsoft Package repository](https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu-install?tabs=dotnet8&pivots=os-linux-ubuntu-2004) to install .NET deb files built and published by the .NET team.
+
+## .NET Core Versions from Ubuntu 2404
+
+The .NET Core team have worked with Canonical and Ubuntu now provides its own .NET packages.
+
+These are the recommended install path and, as-such what is installed on the image.
+
+> The release of Ubuntu 24.04 is just around the corner. Canonical-produced .NET 6, 7, and 8 packages will be available on day one, for "Noble Numbat". Microsoft will not be publishing .NET packages to the 24.04 feed at packages.microsoft.com.
+
+You can read the [full announcement from .NET team here](https://github.com/dotnet/core/discussions/9258). We'll briefly summarize how this change may impact users of the image.
+
+### [`Feature Bands`](https://learn.microsoft.com/dotnet/core/porting/versioning-sdk-msbuild-vs)
+
+Going forward only the `1xx` feature band will be present in the image as Ubuntu only build and publish this band.
+
+> Most distros, including Ubuntu, stick to the .1xx feature band for the lifetime of a major .NET version. They make this choice because .1xx is (effectively) the "compatibility band". Higher bands can have breaking changes.
+> This means there will no longer be packages available for .2xx and later feature bands. Such packages have been exclusively available from Microsoft. If users see an incompatibility between .1xx and higher feature bands, we ask that you please report it in the dotnet/sdk repo. [link: dotnet/core discussion](https://github.com/dotnet/core/discussions/9258)
+
+If you need a higher feature band for your Actions the recommendation is to use the [`setup-dotnet`](https://github.com/actions/setup-dotnet) action to install the desired version.
+
+### .NET MAUI
+
+.NET MAUI is [not included](https://github.com/dotnet/core/discussions/9258#discussioncomment-9548857) in the Ubuntu .NET package. There is work [ongoing to fix.](https://github.com/dotnet/core/discussions/9258#discussioncomment-9548857)
+
+You should be able to resolve this by using the [`setup-dotnet`](https://github.com/actions/setup-dotnet) action to install the desired version.

-# Debugging Failed Packer Builds
-
-## Step 1: Run packer build `-on-error=ask`
-When you run the `packer build` command, give it the `-on-error=ask` flag.
-By default, `packer build` will delete the resource group as soon as the build fails.
-`-on-error=ask` will pause it and wait for your input so you have time to remote in to the VM and diagnose the failure.
-
-When the build fails, you will see this:
-
-![Ask on error screenshot](/help/resources/askOnError.png "Ask on error screenshot")
-
-## Step 2: Find the resource group name in the build log
-At the beginning of the build log (written to console), find the resource group name for the VM:
-
-![Resource group from log screenshot](/help/resources/resourceGroupName.png "Resource group from log screenshot")
-
-Log into the Azure Portal.  Find that resource group under `Resource groups`.  You should see the resources for the Packer build:

-
-## Step 3: Connect to the VM
-Select the VM in the resource group.  Click `Connect:`
