feature request: set Azure Tags on Packer VM

[baidarka]

Description

Feature request: extra parameter on 'build-image.ps1' script so that Azure tags can be passed along to the temporary Packer VM resource.

Although the Packer templates support the parameter 'azure_tags', the build script 'build-image.ps1' does not support that parameter. It is not possible to set Azure tags on the Packer VM when using 'build-image.ps1' or the Azure pipelines in this repo.
(this is an issue, not a bug; apologies, i could not find a matching issue format)

Hi
we are validating it.

Hi
Packer templates can contain the parameter 'azure_tags to include with many', however the challenge here is how to go about including temporary resource tags without a business case for implementing this and obtaining approval from GitHub.

We request that you give further information or justification to consider it.

Summary

We would like to take advantage of the 'azure_tags' parameter in the Packer templates, for instance here:

• ubuntu-24.04.pkr.hcl#L19
• windows-2022.pkr.hcl#L24

while using the build-image.ps1 script; about here:
build-image.ps1#L46

Please note that these 'azure_tags' are only applied to the temporary Packer VM in Azure, which is used to build an Azure and/or GitHub runner image and subsequently deleted by Packer.

Question

I am not sure what you mean by: 'Packer templates can contain the parameter 'azure_tags to include with many''?
The Packer templates that we intend to address are

Scenario

As a team we provide, amongst others, VM images for self-hosted runners for our organization.
Our build process starts with building images using https://github.com/actions/runner-images.
This build process uses a temporary Packer VM , in Azure, on which an image is composed and sys-prepped.
(after which a validation process is started and optional customization takes place)
This temporary Packer VM, is currently not tagged in Azure.

Problem

Due to internal policies, we cannot just-spin-up-a-VM, let alone a temporary VM downloading a bunch of tooling (even if this takes place in isolation)
Being able to set a couple of tags on such a temporary VM would enable our security team to keep a better view on what it going on. Also, finance wants to keep a tab on costs (using a cost center tag).

Besides, earlier discussions like #discussioncomment-4591809 within this project may benefit from the proposed PR #10884 .
