short_description: This module help users manage objects/buckets in GCS (Google Cloud Storage).
version_added: "1.4"
short_description: This module manages objects/buckets in Google Cloud Storage.
description:
- This module allows users to manage their objects/buckets in GCS in an idempotent way. Users can do operations like PUT, GET and set some pre-canned permissions on those objects.Users can also retrieve the urls to their objects to be used in playbooks. They can also use the module to get the string contents of the objects. Please note that this module is compatible with API version 1 of GCS. so it expects the user to set the default project before using this module, Have a lookt at "https://developers.google.com/storage/docs/reference/v1/apiversion1" to set the default project.
