The following page discusses the Identity and Access Management (IAM) permissions required to perform actions within the Cloud Storage portion of the Google Cloud console. IAM permissions are bundled together to make roles, and you grant roles to users and groups.
Common permissions required for using the Google Cloud console
Certain permissions are broadly necessary in order to use the Google Cloud console:
All actions involving buckets should include
resourcemanager.projects.getandstorage.buckets.listpermissions at the project level.These permissions allow you to access the Buckets page, where you create, view, and update buckets.
All actions that include a billing project in the request require
serviceusage.services.usepermission for the project that's specified.This permission ensures you are authorized to bill the project you specify. Including a billing project is used, for example, when accessing a bucket with Requester Pays enabled.
Permissions required for specific actions
| Action | Required IAM Permissions (in addition to those listed above) |
|---|---|
| Create a bucket | storage.buckets.create |
| Attach a tag to a bucket | storage.buckets.createTagBinding |
| List or filter buckets | No additional permissions |
| List tags directly attached to a bucket | storage.buckets.listTagBindings |
| List both inherited tags and tags directly attached to a bucket | storage.buckets.listEffectiveTags |

1This permission is only required if an object with the same name already exists in the destination bucket.
2This permission is only required when keeping the permissions currently applied to the source object.
3This permission is only required if you do not include a billing project in your request. See Requester Pays Use and access requirements for more information.
4This permission does not apply to buckets with uniform bucket-level access enabled.
5This action does not require storage.objects.list
if it's performed on the details page for the relevant object and you don't
access the details page from the overall list of objects for the bucket.
6This action does not apply to buckets with uniform bucket-level access enabled.
