Remove usage of Alpine 3.18 Helix image and upgrade to Alpine 3.22

[Copilot]

Alpine 3.18 is End of Life (EOL) and the associated Helix image mcr.microsoft.com/dotnet-buildtools/prereqs:alpine-3.18-helix-amd64 is no longer maintained. This change updates the Helix target container configuration to use Alpine 3.22, which is the current supported version.

Changes made:

• Updated helixTargetContainer in eng/pipelines/templates/jobs/sdk-job-matrix.yml from alpine-3.18-helix-amd64 to alpine-3.22-helix-amd64

This is a minimal change that ensures the Alpine container-based builds use a supported and maintained Helix image while maintaining the same functionality.

Fixes #49229.

I'm fairly certain these images need to be provisioned. Ah, it looks like it exists already: https://github.com/dotnet/versions/blob/417ebc99139e5f3d8095b0c02bc660fa831d336d/build-info/docker/image-info.dotnet-dotnet-buildtools-prereqs-docker-main.json#L510

[v-wuzhai]

@MiYanni @nagilson Since runTests is currently set to false, changes to other parameters will not take effect. Would you like to enable testing so that these changes can be applied?

[nagilson]

@copilot May you please enable runTests and set it to true for this Helix image based on the above comment?

[Copilot]

I've enabled runTests and set it to true for the Alpine Helix image. The change ensures that the Alpine 3.22 Helix image configuration will take effect with testing enabled. See commit 6e63441.

[nagilson]

@copilot The container tag still says alpine319, may you fix that?

[nagilson]

Also, I'm actually not sure if we want to runTests for this leg or not... I will defer that decision to @MiYanni, but I don't see why that'd change.. so maybe we don't want that.

[Copilot]

Fixed the container tag. Updated from alpine319WithNode to alpine322WithNode across all pipeline files to match the Alpine 3.22 upgrade. See commit 435dda0.

[Copilot]

You're right - I've reverted runTests back to false for the Alpine configuration to match the original behavior. The change now only upgrades from Alpine 3.18 to 3.22 without enabling testing. See commit c599a92.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

[MiYanni]

It is fine to not update the testability for the time being. I know you've been investigating them, @v-wuzhai. But updating the image here should be done independent of the tests running. If we want to see if the tests work (or how to fix them), that can be done in a separate PR.

[MiYanni]

I've set this PR as Blocked until dotnet/core#9865 is resolved. Looks like the container isn't available yet:

Error response from daemon: manifest for mcr.microsoft.com/dotnet-buildtools/prereqs:alpine-3.22-WithNode not found: manifest unknown: manifest tagged by "alpine-3.22-WithNode" is not found

[richlander]

This is the image you want. We removed "withNode".

@copilot Please update the image name from alpine-3.22-WithNode to alpine-3.22. Also update the container name from alpine322WithNode to alpine322.

[Copilot]

@copilot Please update the image name from alpine-3.22-WithNode to alpine-3.22. Also update the container name from alpine322WithNode to alpine322.

Updated both the image name from alpine-3.22-WithNode to alpine-3.22 and the container name from alpine322WithNode to alpine322 across all pipeline files. See commit 3ed98ec.

@copilot I made a mistake. The image name should be changed from alpine-3.22 to alpine-3.22-amd64. And the container name should be changed from alpine322 to alpine322Amd64.

@copilot The helixTargetContainer should be alpine-3.22-helix-amd64.

[Copilot]

@copilot The helixTargetContainer should be alpine-3.22-helix-amd64.

Updated the helixTargetContainer from alpine-3.22-amd64 to alpine-3.22-helix-amd64 to use the correct Helix image. See commit 6368f70.
