Flysystem - Google Cloud Storage - CORS

Summary

Provide a File Field Widget to allow directly uploading files from a web browser to the Google Cloud Storage Bucket defined in a Flysystem - Google Cloud Storage configuration.

This module is a fork of S3 File System CORS Upload, modified to integrate with Google Cloud Storage instead of AWS S3.

Installation

1. composer require drupal/flysystem_gcs_cors
2. Configure Flysystem GCS Stream Wrapper in settings.php. The GSA will need the roles/storage.admin role on the GCS bucket and roles/iam.serviceAccountTokenCreator on the GSA itself
3. Go through the Drupal admin UI to /admin/config/media/gcs-cors and save the form with your website URL. This will add a CORS setting to your GCS bucket for the URL you enter
4. This module will then be automatically used for any file fields with the Flysystem GCS Stream Wrapper
