Code Review

This pull request migrates the aarch64 builds in the Buildkite pipeline to use the wanda build system. The changes are a good step towards standardizing the build process. However, I've identified a couple of issues. The commands for extracting wheels from built images are brittle and could fail if the wheel is not in the expected root directory. More importantly, it appears the ray-extra Docker images are no longer being pushed to a public registry, which is a regression from the previous pipeline configuration. My review includes suggestions to address these points.

[gemini-code-assist]

The previous implementation for building ray-extra images (lines 154-179 in the original file) included an --upload flag, which resulted in the images being pushed. The new wanda-based build steps for ray-extra only build and cache the images in ECR, but they are not pushed to a public registry like Docker Hub. This appears to be a regression. To restore the original behavior, push steps for ray-extra images should be added, similar to the ones implemented for the ray images (e.g., lines 363-385).

The command mv /tmp/wheels/*.whl .whl/ is brittle as it assumes the wheel file is in the root of the extracted directory and will fail to find wheels in subdirectories. Using find makes the extraction more robust by searching recursively. The mv $(find ...) pattern will also correctly fail if no wheel files are found, preserving the intended failure behavior on missing artifacts.

      - mv $(find /tmp/wheels -name "*.whl") .whl/
