IAM permissions for Cloud Storage

The following tables list the Identity and Access Management (IAM) permissions that are associated with Cloud Storage. IAM permissions are grouped into roles, and you assign roles to users and groups.

Bucket permissions

Bucket permission name	Description
storage.buckets.create	Create new buckets in a project.
storage.buckets.createTagBinding	Create a new tag binding to a bucket.
storage.buckets.delete	Delete buckets.
storage.buckets.deleteTagBinding	Delete the tag binding on a bucket.
storage.buckets.enableObjectRetention	Enable object retention configurations on a bucket.
storage.buckets.exemptFromIpFilter	Exempts the user or service account from IP filtering rules for bucket-level operations.
storage.buckets.get	Read bucket metadata, including listing or reading the Pub/Sub notification configurations on a bucket. This permission alone does not allow you to read IAM policies or IP filtering rules.
storage.buckets.getIamPolicy	Read bucket IAM policies.
storage.buckets.list	List buckets in a project including read bucket metadata. This permission alone does not allow you to list IAM policies or IP filtering rules.
storage.buckets.listEffectiveTags	List all tags associated with a bucket, including tags inherited from higher in the resource hierarchy, such as from the bucket's project.
storage.buckets.listTagBindings	List tags directly attached to a bucket.
storage.buckets.relocate	Relocate buckets between geographic locations.
storage.buckets.restore	Bulk restore objects that have been soft-deleted.
storage.buckets.setIamPolicy	Update bucket IAM policies.
storage.buckets.setIpFilter	Set IP filtering rules on a bucket.
storage.buckets.update	Update bucket metadata including adding or removing a Pub/Sub notification configuration on a bucket and reading bucket metadata when updating. This permission alone does not allow you to update IAM policies, IP filtering rules or read the IAM policies on a bucket during the update.
