This py_binary target for push_ray_image references a source file push_ray_image.py that is not included in this pull request. This will cause the Bazel build to fail. Please either add the missing file or remove this target if it's not intended to be part of this change.

These authentication commands are duplicated across the anyscalebuild, anyscalellmbuild, and anyscalemlbuild push jobs. To improve maintainability and reduce redundancy, consider using YAML anchors and aliases to define these commands once and reuse them in each job. This will make future updates to the authentication process much easier.

The GPU_PLATFORM is hardcoded here. The comment mentions it must match a definition in another file, which makes this brittle. If the default GPU platform changes, this script will require a manual update, which can be easily missed. Consider sourcing this value from a shared configuration file or passing it as a command-line argument to make the script more robust and maintainable.

The logic for parsing the CUDA version string using platform.split('.') is fragile. It assumes a specific format with dots as separators and might fail with an IndexError if the platform string format changes (e.g., cu12-cudnn8). Using a regular expression would be more robust for extracting the version parts. For example: re.match(r"cu(\\d+)\\.(\\d+)", platform).

This function has a lot of repeated code, especially the block for appending rayci_build_id tags, which is identical in all if/elif/else branches. This can be refactored to be more DRY (Don't Repeat Yourself), which improves readability and maintainability. You could determine the tag prefix first, then generate the tags in a single block of code.
