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 modernizes the interaction with Google Cloud Storage within several Jupyter notebooks by migrating from the legacy gsutil command-line tool to the gcloud storage interface. This automated update aims to improve performance, streamline authentication, and ensure consistency with the broader gcloud ecosystem. The changes encompass various storage operations, from bucket creation and listing to object management and IAM policy adjustments. Given the automated nature and potential behavioral nuances between the tools, thorough testing is crucial to prevent disruptions.

Highlights

  • Migration to gcloud storage: This pull request automates the migration of gsutil commands to their gcloud storage equivalents across several Jupyter notebooks, aligning with Google Cloud's recommended practices for interacting with Cloud Storage.
  • Command Replacements: Key gsutil commands such as mb (make bucket), ls (list), rm (remove), cp (copy), and lifecycle set have been replaced with their respective gcloud storage commands, often with updated flags for equivalent functionality.
  • IAM Policy Management: Instances of gsutil iam ch for managing IAM policies have been updated to gcloud storage buckets add-iam-policy-binding. A note has been added to highlight the increased complexity of migrating iam ch commands and the need for careful review.
  • Automated Change: The changes in this pull request were generated automatically by an agent targeting gsutil users, based on the official migration guide.
  • Testing Requirement: Reviewers are explicitly advised to thoroughly test these changes in appropriate environments due to potential subtle differences in behavior and output between gsutil and gcloud storage.

Code Review

This pull request is an automated migration from gsutil to gcloud storage commands across several notebooks. The migration is mostly correct, but I've found a few issues that need manual intervention. These include missing equals signs in gcloud commands and incorrect comment formatting in notebook cells, which could lead to syntax errors. Please review the specific comments for details.

This line is a Python-style comment (# Note...) in a cell where shell commands are being executed (prefixed with !). This will cause a SyntaxError when the notebook cell is run. The comment should be a shell comment, prefixed with ! #. Additionally, it appears to be breaking the JSON format of the notebook file, as it's not a string literal within the source array.

The gcloud storage buckets create command is missing an equals sign for the --location flag. It should be --location=$LOCATION.

This cell contains Python-style comments (# Note..., # TODO...) in a context where shell commands are being executed (prefixed with !). This will cause a SyntaxError when the notebook cell is run. All comments in this cell should be shell comments, prefixed with ! #. Additionally, some comments are not properly quoted as strings in the notebook's JSON structure, which will cause it to fail to load.
