Automated: Migrate {target_path} 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.

Summary of Changes

Hello @bhandarivijay-png, 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 initiates the migration from the legacy gsutil command-line tool to the modern gcloud storage interface for Google Cloud Storage operations. The change, which was automatically generated, updates existing gsutil cp commands to their gcloud storage cp --recursive equivalents within the gce/makeProject script. This transition aims to leverage the improved performance, unified authentication, and consistent command structure offered by gcloud storage, though it necessitates careful review and testing due to potential behavioral differences between the tools.

Highlights

  • Migration to gcloud storage: Replaced gsutil commands with gcloud storage commands for interacting with Google Cloud Storage, aligning with the recommended and modern approach.
  • Automated Change: This change was automatically generated as part of a broader effort to migrate from the legacy gsutil tool.
  • Usage Message Update: The gce/makeProject script's usage instructions were updated to reflect the new gcloud storage cp command.

Code Review

This pull request automates the migration from gsutil to gcloud storage. While the command replacement from gsutil cp -r to gcloud storage cp --recursive is syntactically correct according to the migration guide, my review has uncovered a significant pre-existing issue in the deployment logic. The artifacts uploaded to Google Cloud Storage by this command are not actually used by the GCE instance's startup script, which instead builds the application from source. This makes the upload step redundant. I have added comments with high and medium severity to highlight this issue and suggest corrective actions.

mvn clean package

gsutil cp -r target/${WAR} config/base gs://${BUCKET}/gce/
gcloud storage cp --recursive target/${WAR} config/base gs://${BUCKET}/gce/

high

This command uploads build artifacts to a GCS bucket, but the startup script (scripts/startup-script.sh) used for the GCE instance does not use these artifacts. Instead, it clones the source code from GitHub and builds the project from scratch on the instance. This makes the upload step unnecessary and the deployment process inefficient.

I recommend one of the following fixes:

  1. Remove this gcloud storage cp command and related BUCKET logic if building on the instance is the desired behavior.
  2. (Preferred) Modify scripts/startup-script.sh to download the pre-built artifacts from the GCS bucket. This would significantly speed up instance startup and remove the need to install git and maven on the production instance.

medium

This help message reflects the gcloud storage cp step. As noted in my other comment, this step appears to be redundant because the startup script does not use the uploaded artifacts. This help text should be updated to reflect the actual deployment process, which might mean removing the gcloud storage cp mention if that step is removed.
