mb - Make buckets


gsutil mb [-c class] [-l location] [-p proj_id] url...


The mb command creates a new bucket. Google Cloud Storage has a single namespace, so you are not allowed to create a bucket with a name already in use by another user. You can, however, carve out parts of the bucket name space corresponding to your company's domain name (see "gsutil help naming").

If you don't specify a project ID using the -p option, the bucket is created using the default project ID specified in your gsutil configuration file (see gsutil help config). For more details about projects see gsutil help projects.

The -c and -l options specify the storage class and location, respectively, for the bucket. Once a bucket is created in a given location and with a given storage class, it cannot be moved to a different location, and the storage class cannot be changed. Instead, you would need to create a new bucket and move the data over and then delete the original bucket.

Bucket Storage Classes

You can specify one of the storage classes for a bucket with the -c option.


gsutil mb -c nearline gs://some-bucket

See online documentation for pricing and SLA details.

If you don't specify a -c option, the bucket is created with the default storage class Standard Storage, which is equivalent to Multi-Regional Storage or Regional Storage, depending on whether the bucket was created in a multi-regional location or regional location, respectively.

Bucket Locations

You can specify one of the available locations for a bucket with the -l option.


gsutil mb -l asia gs://some-bucket

gsutil mb -c regional -l us-east1 gs://some-bucket

If you don't specify a -l option, the bucket is created in the default location (US).


-c class Specifies the default storage class. Default is "Standard".
-l location Can be any multi-regional or regional location. See https://cloud.google.com/storage/docs/bucket-locations for a discussion of this distinction. Default is US. Locations are case insensitive.
-p proj_id Specifies the project ID under which to create the bucket.
-s class Same as -c.
