Parameter Description

Parameter

Optional or Mandatory

Description

bucket

Mandatory

Bucket name

sc

Optional (additional parameter)

Default storage class of the bucket. Possible values are:

  • standard: Standard storage class. It features low access latency and high throughput, and is applicable to storing frequently accessed data (multiple accesses per month) or data that is smaller than 1 MB.
  • warm: Warm storage class. It is ideal for storing infrequently accessed (less than 12 times a year) data, but when needed, the access has to be fast.
  • cold: Cold storage class. It provides secure, durable, and inexpensive storage for rarely-accessed (once a year) data.
NOTE:

If the multi-AZ mode is enabled for a bucket, the default storage class of the bucket cannot be set to cold.

acl

Optional (additional parameter)

Access control policies that can be specified for buckets. Possible values are:

  • private
  • public-read
  • public-read-write
NOTE:

The preceding three values indicate private read and write, public read, and public read and write.

aclXml

Optional (additional parameter)

Access control policy of the bucket, in XML format.

<AccessControlPolicy>
    <Owner>
        <ID>ownerid</ID>
    </Owner>
    <AccessControlList>
        <Grant>
            <Grantee>
                <ID>userid</ID>
            </Grantee>
            <Permission>[WRITE|WRITE_ACP|READ|READ_ACP|FULL_CONTROL]</Permission>
        </Grant>
        <Grant>
            <Grantee>
                <Canned>Everyone</Canned>
            </Grantee>
            <Permission>[WRITE|WRITE_ACP|READ|READ_ACP|FULL_CONTROL]</Permission>
        </Grant>
    </AccessControlList>
</AccessControlPolicy>
NOTE:
  • Owner: Optional. Specify the bucket owner's ID.
  • In AccessControlList, the Grant field contains the authorized users. Grantee specifies the IDs of authorized users. Canned specifies the authorized user group (currently, only Everyone is supported).
  • The following permissions can be granted: WRITE (write), WRITE_ACP (write ACL), READ (read), READ_ACP (read ACL), and FULL_CONTROL (full control).
NOTICE:

Because angle brackets (<) and (>) are unavoidably included in the parameter value, you must use quotation marks to enclose them for escaping when running the command. Use single quotation marks for Linux or macOS and quotation marks for Windows.

config

Optional (additional parameter)

User-defined configuration file for executing a command. For details about parameters that can be configured, see Parameter Description.

Only one from sc, acl, or aclXml can be set for each command.
