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 existing gsutil command-line invocations to use the gcloud storage command-line interface across several Python scripts and Jupyter notebooks. This migration is part of an ongoing initiative to standardize interactions with Google Cloud Storage, leveraging the gcloud storage tool for its enhanced performance, unified authentication, and consistent command structure within the broader gcloud ecosystem. The changes, generated automatically, include important inline comments to guide users on potential behavioral shifts, especially concerning bucket listing outputs and IAM policy modifications, emphasizing the need for thorough review and testing.

Highlights

  • Automated Migration: This pull request was automatically generated by an agent to migrate gsutil commands to gcloud storage commands, aligning with the recommended modern tool for Google Cloud Storage interactions.
  • Command Replacements: Key gsutil commands such as cat, mb (make bucket), ls (list), iam ch (IAM change), cp (copy), and rm (remove) have been replaced with their gcloud storage equivalents across various Python scripts and Jupyter notebooks.
  • Behavioral Differences Noted: Comments have been added to the code, particularly in Jupyter notebooks, to highlight potential differences in behavior between gsutil and gcloud storage, such as the output format of ls and the more complex migration path for iam ch commands.
  • Impacted Files: The changes affect a core cloud-build helper script and numerous Jupyter notebooks within the community/model_garden, official/automl, official/generative_ai, official/ml_metadata, and official/prediction directories.

Code Review

This pull request contains automated changes to migrate from gsutil to gcloud storage commands across several Python scripts and Jupyter notebooks. While most of the migrations are correct, I've identified a recurring critical issue in three notebooks. The automation failed to account for a change in the output format of gcloud storage ls --full compared to gsutil ls -L. Specifically, the key "Location constraint" is now "Location Constraint" (title case). The existing code still greps for the lowercase version, which will cause the command to fail and raise an IndexError in the notebooks, breaking their execution. I've provided suggestions to fix this in each of the affected files.

" 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\".\n",
" 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",

The gcloud storage ls --full command uses title case for keys in its output, such as "Location Constraint". The grep command is still using the lowercase "Location constraint:", which was correct for gsutil but will fail with gcloud storage. This will cause the shell_output to be empty and lead to an IndexError on the next line. Please update the grep and sed commands to use the correct title case string.

Suggested change
" 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",
" shell_output = ! gcloud storage ls --full --buckets {BUCKET_NAME} | grep \"Location Constraint:\" | sed \"s/Location Constraint://\"\n",
