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: [email protected]

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 systematically updates numerous Jupyter notebooks by replacing deprecated gsutil command-line interface calls with the modern gcloud storage CLI. This migration is an automated effort to standardize interactions with Google Cloud Storage, leveraging the improved performance, unified authentication, and consistent command structure offered by gcloud storage. Reviewers are advised to carefully test these changes due to potential subtle differences in command behavior and output structure between the two tools.

Highlights

  • Automated Migration: This pull request automates the migration of gsutil commands to their gcloud storage equivalents across several Jupyter notebooks, aligning with the recommended modern tool for Google Cloud Storage interactions.
  • Command Replacements: Key gsutil commands such as mb (make bucket), ls (list), cp (copy), rm (remove), and cat (concatenate) have been replaced with their respective gcloud storage commands, often with updated flags for equivalent functionality.
  • IAM Policy Binding Updates: Instances of gsutil iam ch for managing IAM policies have been updated to gcloud storage buckets add-iam-policy-binding, with inline comments noting the increased complexity of migrating iam ch commands.
  • Impacted Notebooks: The changes span across various community and official notebooks, including those related to explainable AI, legacy migrations, MLOps pipelines, model garden deployments (Gemma2, Llama3), and vector search.

Code Review

This automated pull request correctly migrates gsutil commands to their gcloud storage equivalents. However, the automation script has introduced critical formatting errors in all the updated Jupyter notebook files. It consistently merges lines within the source array of code cells, which breaks the JSON structure of the notebooks and renders them invalid. These formatting issues must be fixed across all files to ensure the notebooks can be loaded and executed correctly.

"source": [
"! gsutil mb -l $REGION -p $PROJECT_ID $BUCKET_URI"
]
"! gcloud storage buckets create --location=$REGION --project=$PROJECT_ID $BUCKET_URI" ]

This line was incorrectly merged with the closing bracket of the array, which breaks the JSON structure of the notebook. It should be two separate lines. Similar formatting issues exist elsewhere in this file.
