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 automates the migration of various Google Cloud Storage command-line operations from the legacy gsutil tool to the recommended gcloud storage interface across several Jupyter notebooks. This update is part of a broader initiative to standardize GCS interactions, leveraging the improved performance, unified authentication, and consistent command structure offered by gcloud storage. Reviewers are encouraged to thoroughly test these changes, as behavioral differences between the tools, such as command output formats and file deletion logic, could impact existing workflows.

Highlights

  • Bucket Creation: All instances of gsutil mb for creating storage buckets have been updated to use the modern gcloud storage buckets create command, ensuring consistency with the new CLI.
  • Listing Objects: Commands for listing storage objects, previously using gsutil ls, are now migrated to gcloud storage ls, often including --all-versions --long for equivalent detailed output.
  • Content Retrieval: The gsutil cat command, used for displaying object content, has been uniformly replaced with gcloud storage cat across the affected notebooks.
  • Copying Objects: File and directory copying operations, which used gsutil cp, have been updated to gcloud storage cp, with --recursive added where appropriate for directory transfers.
  • Deleting Objects: Commands for removing storage objects and buckets, previously gsutil rm, are now gcloud storage rm --recursive, with --continue-on-error added in one specific case for robustness.
  • IAM Policy Management: The gsutil iam ch command for managing IAM policies has been replaced with gcloud storage buckets add-iam-policy-binding, noting the more complex migration path for IAM changes.

Code Review

This pull request migrates gsutil commands to gcloud storage in several notebook files. The changes primarily involve replacing gsutil with gcloud storage and updating command-line arguments to match the gcloud storage syntax. I have identified some opportunities to improve the accuracy of the migrated commands, and to ensure the bucket names are correctly formatted.

The gcloud storage buckets create command requires the bucket name to be specified as a URI (e.g., gs://my-bucket). It's crucial to ensure that $BUCKET_NAME includes the gs:// prefix. If $BUCKET_NAME does not include the gs:// prefix, the command will fail.

Consider adding the gs://$BUCKET_NAME to ensure the bucket name is correctly formatted.

ERROR: (gcloud.storage.buckets.create) "gcloud storage buckets create" only accepts bucket URLs.

Hence Gemini incorrect ..

This command is using gcloud storage cat to read the contents of a file, but it's missing a newline character at the end. This could cause issues when parsing the output, especially if the file is large or if the parsing logic relies on complete lines.

Consider adding a newline character (\n) to the end of the gcloud storage cat command to ensure that the output is properly formatted.
