SYNOPSIS
""" + _SYNOPSIS + """

DESCRIPTION
 Create one or more new buckets. 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 or project number using the -p option, the
 buckets are created using the default project ID specified in your `gsutil
 configuration file <https://cloud.google.com/storage/docs/boto-gsutil>`_.

The -l option specifies the location for the buckets. Once a bucket is created
  in a given location, it cannot be moved to a different location. Instead, you
  need to create a new bucket, move the data over, and then delete the original
  bucket.

BUCKET STORAGE CLASSES
 You can specify one of the `storage classes
 <https://cloud.google.com/storage/docs/storage-classes>`_ for a bucket
 with the -c option.

Example:

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

See online documentation for
 `pricing <https://cloud.google.com/storage/pricing>`_ and
 `SLA <https://cloud.google.com/storage/sla>`_ details.

If you don't specify a -c option, the bucket is created with the
  default storage class Standard Storage.

BUCKET LOCATIONS
 You can specify one of the `available locations
 <https://cloud.google.com/storage/docs/locations>`_ for a bucket
 with the -l option.

Examples:

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

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

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

Retention Policy
 You can specify retention period in one of the following formats:

--retention <number>s
 Specifies retention period of <number> seconds for objects in this bucket.

--retention <number>d
 Specifies retention period of <number> days for objects in this bucket.

--retention <number>m
 Specifies retention period of <number> months for objects in this bucket.

--retention <number>y
 Specifies retention period of <number> years for objects in this bucket.

Examples:

gsutil mb --retention 1y gs://some-bucket

gsutil mb --retention 36m gs://some-bucket

If you don't specify a --retention option, the bucket is created with no
  retention policy.

OPTIONS
 --autoclass Enables the Autoclass feature that automatically
 sets object storage classes.

-b <on|off> Specifies the uniform bucket-level access setting.
 When "on", ACLs assigned to objects in the bucket are
 not evaluated. Consequently, only IAM policies grant
 access to objects in these buckets. Default is "off".

-c class Specifies the default storage class. Default is
 ``Standard``. See `Available storage classes
 <https://cloud.google.com/storage/docs/storage-classes#classes>`_
 for a list of possible values.

-k <key> Set the default KMS key using the full path to the key,
 which has the following form:
 ``projects/[project-id]/locations/[location]/keyRings/[key-ring]/cryptoKeys/[my-key]``

-l location            Can be any supported location. See
                         https://cloud.google.com/storage/docs/locations
                         for a discussion of this distinction. Default is US.
                         Locations are case insensitive.

-p project             Specifies the project ID or project number to create
                         the bucket under.

-s class               Same as -c.

--retention time       Specifies the retention policy. Default is no retention
                         policy. This can only be set on gs:// buckets and
                         requires using the JSON API. For more details about
                         retention policy see "gsutil help retention"

--pap setting          Specifies the public access prevention setting. Valid
                         values are "enforced" or "inherited". When
                         "enforced", objects in this bucket cannot be made
                         publicly accessible. Default is "inherited".

--placement reg1,reg2  Two regions that form the custom dual-region.
                         Only regions within the same continent are or will ever
                         be valid. Invalid location pairs (such as
                         mixed-continent, or with unsupported regions)
                         will return an error.

--rpo setting Specifies the `replication setting
 <https://cloud.google.com/storage/docs/availability-durability#cross-region-redundancy>`_.
 This flag is not valid for single-region buckets,
 and multi-region buckets only accept a value of
 DEFAULT. Valid values for dual region buckets
 are {rpo_values}. If unspecified, DEFAULT is applied
 for dual-region and multi-region buckets.
