Create a bucket

To create a bucket, you make a PUT request that includes an x-goog-project-id header, and you include bucket settings such as the bucket's location and default storage class in the request body. Note that certain settings, such as a bucket's location, can only be set at creation time. Additionally, the XML API does not support all settings at bucket creation time, such as a bucket's Object Lifecycle Management configuration. Such settings can only be specified in a metadata update request after bucket creation.

Your bucket name must be unique across the global Cloud Storage namespace. If your bucket name is in use, you get a 409 Conflict error, and the bucket creation request fails. Similarly, requests that attempt to create a bucket with an invalid name fail. For more information, see bucket naming guidelines.

You can only create a bucket in projects for which you have permission to do so. For example, if you have the Storage Admin role on a project, you have the required permission (storage.buckets.create) to create buckets.

Request body elements

The following request body elements are applicable when creating a bucket. If you don't specify a request body, Cloud Storage creates a bucket in the US location with a default storage class of STANDARD.

Element Description
