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.

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 migrates all instances of gsutil commands to the recommended gcloud storage command-line interface within several Jupyter notebooks. This update aligns the notebooks with the modern and unified gcloud ecosystem, offering improved performance and consistent authentication. The changes were automatically generated based on the official migration guide, ensuring a standardized transition while highlighting areas that require careful review due to command behavior differences, particularly for IAM and listing operations.

Highlights

  • Command Migration: Replaced all instances of gsutil commands with their modern gcloud storage equivalents across various Jupyter notebooks.
  • IAM Policy Updates: Updated gsutil iam ch commands to gcloud storage buckets add-iam-policy-binding, with inline notes highlighting the increased complexity and differences in IAM policy management.
  • Bucket Listing and Management: Adjusted gsutil ls commands to gcloud storage ls and gsutil mb to gcloud storage buckets create, including considerations for output format differences and new flag requirements.
  • Automated Change: This pull request was automatically generated by an agent as part of an ongoing effort to modernize Google Cloud Storage interactions.

Code Review

This pull request contains automated migrations from gsutil to gcloud storage across several Jupyter notebooks. While most of the command migrations appear correct, I've identified critical syntax errors in two of the notebooks (get_started_with_hpt_pipeline_components.ipynb and model_garden_pytorch_llama3_3_finetuning.ipynb). The automated script has inserted unquoted comments into the notebook's JSON structure, which will cause these notebooks to fail to load or execute. I have provided code suggestions to fix these issues. Please review these fixes and test the notebooks thoroughly before merging.

Comment on lines 534 to 537
# Note: Migrating scripts using gsutil iam ch is more complex than get or set. You need to replace the single iam ch command with a series of gcloud storage bucket add-iam-policy-binding and/or gcloud storage bucket remove-iam-policy-binding commands, or replicate the read-modify-write loop.
# Note: Conditions: gsutil iam ch does not support modifying IAM policies that contain conditions. gcloud storage commands do support conditions.
# Note: File Argument Order: In gsutil iam set, the policy file comes before the URLs. In gcloud storage bucket set-iam-policy, the policy file comes after the URL.

The automated migration introduced a syntax error in this notebook cell. The comments on lines 534-536 and the command on line 537 are not enclosed in quotes, which makes the JSON for this cell's source array invalid. This will cause the notebook to fail to load or execute. All lines within the source array must be valid strings.
