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 systematically migrates existing gsutil commands to their gcloud storage equivalents across several Jupyter notebooks. This automated update aligns with the ongoing initiative to transition to the more modern and feature-rich gcloud storage command-line interface for interacting with Google Cloud Storage. Reviewers are encouraged to thoroughly test these changes, as subtle behavioral differences between the tools, particularly concerning rsync and iam ch commands, could impact existing workflows.

Highlights

  • Automated Migration: This pull request automates the migration of gsutil commands to their gcloud storage equivalents across multiple Jupyter notebooks.
  • Command Replacements: Key gsutil commands such as mb (make bucket), ls (list), iam ch (IAM policy change), cp (copy), and rm (remove) have been updated to their respective gcloud storage syntax.
  • Migration Notes: New comments have been added within the notebooks to highlight potential complexities, especially regarding gsutil iam ch migration and differences in ls command output formats.

Code Review

This pull request automates the migration from gsutil to gcloud storage across several Jupyter notebooks. The changes are largely correct and follow the migration guide. However, I found a couple of critical issues where the automated script produced invalid JSON in the notebook files by not properly quoting lines within the source cells. This would cause the notebooks to fail to load. I've provided suggestions to fix these issues.

Comment on lines 548 to 549
# 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.

The automated migration has introduced a syntax error that will corrupt the notebook file. The source field in a notebook cell must be an array of strings. In this change, the comment on line 548 and the shell command on line 549 are not enclosed in quotes, making the JSON invalid. Additionally, the closing bracket ] for the array has been moved to the end of line 549, which is also incorrect.

        "# 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.",

This comment line is not a valid JSON string because it is not enclosed in quotes. Each element in the source array of a notebook cell must be a string. This will cause an error when loading the notebook.
