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.

Code Review

This pull request automates the migration from gsutil to gcloud storage commands. The changes are correct and align with the migration goal. I've provided a couple of suggestions to further improve the scripts by using the --if-not-exists flag with gcloud storage buckets create. This makes the operations more robust, idempotent, and user-friendly.

While this is a correct translation from gsutil, you can make this operation more robust and efficient by using the --if-not-exists flag with gcloud storage buckets create. This performs an atomic 'create if not exists' operation, avoiding a potential race condition and simplifying the code to a single command.

Suggested change
if ! gcloud storage ls "gs://${BUCKET_NAME}" > /dev/null 2>&1; then
boldout "Creating a storage bucket to hold the custom target configuration"
gcloud -q storage buckets create --project "${PROJECT}" --location "${REGION}" "gs://${BUCKET_NAME}"
fi
boldout "Ensuring storage bucket exists to hold the custom target configuration"
gcloud -q storage buckets create --project "${PROJECT}" --location "${REGION}" "gs://${BUCKET_NAME}" --if-not-exists

Comment on lines +83 to +85

For a better user experience in this quickstart, consider adding the --if-not-exists flag. This will prevent errors if the user runs the script multiple times, making the bucket creation step idempotent.

Suggested change
gcloud storage buckets create gs://$STAGING_BUCKET_NAME --location $STAGING_REGION --project $STAGING_PROJECT_ID
gsutil mb -l $PROD_REGION -p $PROD_PROJECT_ID gs://$PROD_BUCKET_NAME
gcloud storage buckets create gs://$PROD_BUCKET_NAME --location $PROD_REGION --project $PROD_PROJECT_ID
gcloud storage buckets create gs://$STAGING_BUCKET_NAME --location $STAGING_REGION --project $STAGING_PROJECT_ID --if-not-exists
gcloud storage buckets create gs://$PROD_BUCKET_NAME --location $PROD_REGION --project $PROD_PROJECT_ID --if-not-exists
