Automated: Migrate paths from gsutil to gcloud storage

This CL is part of the on going effort to migrate from the legacy gsutil tool to the new and improved gcloud storage command-line interface. gcloud storage is the recommended and modern tool for interacting with Google Cloud Storage, offering better performance, unified authentication, and a more consistent command structure with other gcloud components. 🚀

Automation Details

This change was generated automatically by an agent that targets users of gsutil.
The transformations applied are based on the gsutil to gcloud storage migration guide.

⚠️ Action Required: Please Review and Test Carefully

While we have based the automation on the migration guide, every use case is unique.
It is crucial that you thoroughly test these changes in environments appropriate to your use-case before merging.
Be aware of potential differences between gsutil and gcloud storage that could impact your workflows.
For instance, the structure of command output may have changed, requiring updates to any scripts that parse it. Similarly, command behavior can differ subtly; the gcloud storage rsync command has a different file deletion logic than gsutil rsync, which could lead to unintended file deletions.

Our migration guides can help guide you through a list of mappings and some notable differences between the two tools.

Standard presubmit tests are run as part of this CL's workflow. If you need to target an additional test workflow or require assistance with testing, please let us know.

Please verify that all your Cloud Storage operations continue to work as expected to avoid any potential disruptions in production.

Support and Collaboration

The GCS CLI team is here to help! If you encounter any issues, have a complex use case that this automated change doesn't cover, or face any other blockers, please don't hesitate to reach out.
We are happy to work with you to test and adjust these changes as needed.

Contact: gcs-cli-hyd@google.com

We appreciate your partnership in this important migration effort!

Summary of Changes

Hello @googlyrahman, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates various Google Cloud Storage operations within several notebooks, transitioning from the legacy gsutil command-line tool to the modern gcloud storage CLI. This change aims to align the codebase with current best practices for interacting with Google Cloud Storage, leveraging the benefits of the newer tool. While automated, careful review and testing are crucial to ensure seamless integration and avoid potential disruptions due to subtle command behavior differences.

Highlights

  • Automated Migration: This pull request automatically migrates existing gsutil commands to their gcloud storage equivalents across several notebooks. This is part of an ongoing effort to standardize interactions with Google Cloud Storage using the modern gcloud storage CLI.
  • Modern Tooling: The gcloud storage command-line interface is the recommended and modern tool for Google Cloud Storage, offering improved performance, unified authentication, and a consistent command structure with other gcloud components.
  • Migration Guide Adherence: The transformations applied are based on the official gsutil to gcloud storage migration guide, ensuring consistency with recommended practices.
  • Action Required: Review and Test: Reviewers are advised to thoroughly test these changes in appropriate environments before merging, as behavioral differences between gsutil and gcloud storage (e.g., rsync logic, command output) could impact existing workflows. Support is available from the GCS CLI team for complex cases or testing assistance.

Code Review

This pull request automates the migration of gsutil commands to the newer gcloud storage commands across several notebooks. The automated changes are largely correct and cover various commands like mb, ls, cp, and rm with their respective flags. However, I found one instance where the automation failed to migrate a gsutil copy command, leaving it as a TODO. I've provided a suggestion to complete this migration. Overall, a good automated update, but this one manual fix is required.

The automated migration script correctly flagged that it could not find gsutil copy in its migration guide. The copy command is an alias for cp in gsutil. The correct migration is to use gcloud storage cp.

        ! gcloud storage cp $PUBLIC_TRAINING_DATASET $TRAINING_URI
