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 updates various Jupyter notebooks to use the modern gcloud storage command-line interface instead of the legacy gsutil tool. This automated effort aims to align the notebooks with Google Cloud's recommended practices for interacting with Cloud Storage, promising better performance and a more consistent user experience. Reviewers are urged to carefully test the updated commands to ensure compatibility and prevent unexpected workflow disruptions.

Highlights

  • Automated Migration: This pull request was automatically generated by an agent to migrate gsutil commands to gcloud storage commands across multiple Jupyter notebooks.
  • Command Replacements: Key gsutil commands such as mb, ls, cat, cp, and rm have been replaced with their gcloud storage equivalents, including updated flags and syntax.
  • IAM Policy Migration: The migration of gsutil iam ch commands to gcloud storage buckets add-iam-policy-binding includes important notes regarding the increased complexity and handling of conditions in the new gcloud storage commands.
  • Testing Requirement: The author emphasizes the critical need for thorough review and testing of these changes in appropriate environments due to potential subtle differences in command behavior and output structure between gsutil and gcloud storage.

Code Review

This pull request automates the migration of gsutil commands to their gcloud storage equivalents across several Jupyter notebooks. The automated migration is largely successful, with most commands being correctly translated. However, I've identified a critical issue in one of the notebooks where parsing the output of a gcloud command will fail due to a case-sensitivity mismatch. Additionally, there are some minor inconsistencies in command-line flag formatting that should be addressed for better code quality and maintainability. After fixing these issues, the changes should be good to merge.

" shell_output = ! gsutil ls -Lb {BUCKET_NAME} | grep \"Location constraint:\" | sed \"s/Location constraint://\"\n",
" bucket_region = shell_output[0].strip().lower()\n",
# Note: The format of the full listing output is different. gcloud storage uses a title case for keys and will not display a field if its value is "None".
" shell_output = ! gcloud storage ls --full --buckets {BUCKET_NAME} | grep \"Location constraint:\" | sed \"s/Location constraint://\"\n", " bucket_region = shell_output[0].strip().lower()\n",

This command will fail because it's parsing the output of gcloud storage ls incorrectly. The note on the previous line correctly points out that gcloud storage uses title case for keys, so grep should be looking for Location Constraint: instead of Location constraint:. The sed command also needs to be updated to match the title case string.

    shell_output = ! gcloud storage ls --full --buckets {BUCKET_NAME} | grep "Location Constraint:" | sed "s/Location Constraint: *//"

For consistency with other commands in this pull request and general gcloud command-line style, it's better to use a space to separate the --location flag and its value, rather than an equals sign.
