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 updates various Jupyter notebooks to replace gsutil commands with their gcloud storage equivalents. This change is part of an ongoing effort to modernize GCS interactions, ensuring that all examples and workflows utilize the recommended and more efficient gcloud storage tool. The migration was performed automatically, but careful validation is advised to prevent any unforeseen impacts on existing processes.

Highlights

  • Automated Migration: This pull request automates the migration of Google Cloud Storage (GCS) command-line operations from the legacy gsutil tool to the modern gcloud storage command-line interface across multiple Jupyter notebooks.
  • Enhanced Functionality: The transition to gcloud storage leverages its improved performance, unified authentication, and a more consistent command structure, aligning with Google Cloud's recommended practices for interacting with GCS.
  • Action Required: Careful Review and Testing: While automated, it is crucial for reviewers to thoroughly test these changes due to potential subtle differences in command behavior and output structure between gsutil and gcloud storage, such as the rsync deletion logic or IAM policy modifications.

Code Review

This pull request automates the migration of gsutil commands to gcloud storage across several Jupyter notebooks. The automated changes are largely correct and align with the migration guide. I have identified two areas for improvement. First, I've corrected a shell command that was inefficient and potentially buggy, replacing it with a more idiomatic and robust version. Second, I've adjusted a gcloud command to ensure consistency in flag usage across the project. With these changes, the migration will be more robust and maintainable.

This command is inefficient and the use of the pipe | is likely incorrect. It creates a local file instruction.txt and then attempts to upload it, but the pipe | sends the (empty) stdout of the echo >> command to gcloud storage cp, which is not the intended behavior. A more idiomatic and efficient approach is to pipe the output of echo directly to gcloud storage cp using - for stdin. This avoids creating an unnecessary local file.

! echo "this is instruction" | gcloud storage cp - "$BUCKET_URI/instruction.txt"

For consistency with other gcloud commands in this pull request and for better readability, it's recommended to use an equals sign for assigning values to flags. While gcloud often accepts a space, using = is more explicit and less prone to parsing errors.
