--file-share-arn (string)

The Amazon Resource Name (ARN) of the file share to be updated.

--kms-encrypted | --no-kms-encrypted (boolean)

True to use Amazon S3 server-side encryption with your own AWS KMS key, or false to use a key managed by Amazon S3. Optional.

--kms-key (string)

The Amazon Resource Name (ARN) of the AWS KMS key used for Amazon S3 server-side encryption. This value can only be set when KMSEncrypted is true. Optional.

--nfs-file-share-defaults (structure)

The default values for the file share. Optional.

JSON Syntax:

  "FileMode": "string",
  "DirectoryMode": "string",
  "GroupId": long,
  "OwnerId": long

--default-storage-class (string)

The default storage class for objects put into an Amazon S3 bucket by the file gateway. Possible values are S3_STANDARD , S3_STANDARD_IA , or S3_ONEZONE_IA . If this field is not populated, the default value S3_STANDARD is used. Optional.

--object-acl (string)

A value that sets the access control list permission for objects in the S3 bucket that a file gateway puts objects into. The default value is "private".

Possible values:

  • private
  • public-read
  • public-read-write
  • authenticated-read
  • bucket-owner-read
  • bucket-owner-full-control
  • aws-exec-read

--client-list (list)

The list of clients that are allowed to access the file gateway. The list must contain either valid IP addresses or valid CIDR blocks.

--squash (string)

The user mapped to anonymous user. Valid options are the following:

  • RootSquash - Only root is mapped to anonymous user.
  • NoSquash - No one is mapped to anonymous user
  • AllSquash - Everyone is mapped to anonymous user.

--read-only | --no-read-only (boolean)

A value that sets the write status of a file share. This value is true if the write status is read-only, and otherwise false.

--guess-mime-type-enabled | --no-guess-mime-type-enabled (boolean)

A value that enables guessing of the MIME type for uploaded objects based on file extensions. Set this value to true to enable MIME type guessing, and otherwise to false. The default value is true.

--requester-pays | --no-requester-pays (boolean)

A value that sets who pays the cost of the request and the cost associated with data download from the S3 bucket. If this value is set to true, the requester pays the costs. Otherwise the S3 bucket owner pays. However, the S3 bucket owner always pays the cost of storing data.


RequesterPays is a configuration for the S3 bucket that backs the file share, so make sure that the configuration on the file share is the same as the S3 bucket configuration.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


FileShareARN -> (string)

The Amazon Resource Name (ARN) of the updated file share.
