CreateNFSFileShare

Creates a Network File System (NFS) file share on an existing S3 File Gateway. In Storage Gateway, a file share is a file system mount point backed by Amazon S3 cloud storage. Storage Gateway exposes file shares using an NFS interface. This operation is only supported for S3 File Gateways.

Important

S3 File gateway requires AWS Security Token Service (AWS STS) to be activated to enable you to create a file share. Make sure AWS STS is activated in the AWS Region you are creating your S3 File Gateway in. If AWS STS is not activated in the AWS Region, activate it. For information about how to activate AWS STS, see Activating and deactivating AWS STS in an AWS Region in the AWS Identity and Access Management User Guide.

S3 File Gateways do not support creating hard or symbolic links on a file share.

Type: String

Length Constraints: Minimum length of 5. Maximum length of 50.

Required: No

EncryptionType

A value that specifies the type of server-side encryption that the file share will use for the data that it stores in Amazon S3.

Note

We recommend using EncryptionType instead of KMSEncrypted to set the file share encryption method. You do not need to provide values for both parameters.

If values for both parameters exist in the same request, then the specified encryption methods must not conflict. For example, if EncryptionType is SseS3, then KMSEncrypted must be false. If EncryptionType is SseKms or DsseKms, then KMSEncrypted must be true.

Type: String

Valid Values: SseS3 | SseKms | DsseKms

Required: No

FileShareName

The name of the file share. Optional.

Note

FileShareName must be set if an S3 prefix name is set in LocationARN, or if an access point or access point alias is used.

A valid NFS file share name can only contain the following characters: a-z, A-Z, 0-9, -, ., and _.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Required: No

GatewayARN

The Amazon Resource Name (ARN) of the S3 File Gateway on which you want to create a file share.

Type: String

Length Constraints: Minimum length of 50. Maximum length of 500.

Required: Yes

GuessMIMETypeEnabled

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, otherwise set to false. The default value is true.

Valid Values: true | false

Type: Boolean

Required: No

KMSEncrypted

This parameter has been deprecated.

Optional. Set to true to use Amazon S3 server-side encryption with your own AWS KMS key (SSE-KMS), or false to use a key managed by Amazon S3 (SSE-S3). To use dual-layer encryption (DSSE-KMS), set the EncryptionType parameter instead.

Note

We recommend using EncryptionType instead of KMSEncrypted to set the file share encryption method. You do not need to provide values for both parameters.

If values for both parameters exist in the same request, then the specified encryption methods must not conflict. For example, if EncryptionType is SseS3, then KMSEncrypted must be false. If EncryptionType is SseKms or DsseKms, then KMSEncrypted must be true.

Valid Values: true | false

Type: Boolean

Required: No

KMSKey

Optional. The Amazon Resource Name (ARN) of a symmetric customer master key (CMK) used for Amazon S3 server-side encryption. Storage Gateway does not support asymmetric CMKs. This value must be set if KMSEncrypted is true, or if EncryptionType is SseKms or DsseKms.

Type: String

Length Constraints: Minimum length of 7. Maximum length of 2048.

Pattern: (^arn:(aws(|-cn|-us-gov|-iso[A-Za-z0-9_-]*)):kms:([a-zA-Z0-9-]+):([0-9]+):(key|alias)/(\S+)$)|(^alias/(\S+)$)

Required: No

LocationARN

A custom ARN for the backend storage used for storing data for file shares. It includes a resource ARN with an optional prefix concatenation. The prefix must end with a forward slash (/).

Note

You can specify LocationARN as a bucket ARN, access point ARN or access point alias, as shown in the following examples.

Bucket ARN:

arn:aws:s3:::amzn-s3-demo-bucket/prefix/

Access point ARN:

arn:aws:s3:region:account-id:accesspoint/access-point-name/prefix/

If you specify an access point, the bucket policy must be configured to delegate access control to the access point. For information, see Delegating access control to access points in the Amazon S3 User Guide.

Access point alias:

test-ap-ab123cdef4gehijklmn5opqrstuvuse1a-s3alias

Type: String

Length Constraints: Minimum length of 16. Maximum length of 1400.

Required: Yes

NFSFileShareDefaults

File share default values. Optional.

Type: NFSFileShareDefaults object

Required: No

NotificationPolicy

The notification policy of the file share. SettlingTimeInSeconds controls the number of seconds to wait after the last point in time a client wrote to a file before generating an ObjectUploaded notification. Because clients can make many small writes to files, it's best to set this parameter for as long as possible to avoid generating multiple notifications for the same file in a small time period.

Note

SettlingTimeInSeconds has no effect on the timing of the object uploading to Amazon S3, only the timing of the notification.

This setting is not meant to specify an exact time at which the notification will be sent. In some cases, the gateway might require more than the specified delay time to generate and send notifications.

The following example sets NotificationPolicy on with SettlingTimeInSeconds set to 60.

{\"Upload\": {\"SettlingTimeInSeconds\": 60}}

The following example sets NotificationPolicy off.

{}

Type: String

Length Constraints: Minimum length of 2. Maximum length of 100.

Pattern: ^\{[\w\s:\{\}\[\]"]*}$

Required: No

ObjectACL

A value that sets the access control list (ACL) permission for objects in the S3 bucket that a S3 File Gateway puts objects into. The default value is private.

Type: String

Valid Values: private | public-read | public-read-write | authenticated-read | bucket-owner-read | bucket-owner-full-control | aws-exec-read

Required: No

ReadOnly

A value that sets the write status of a file share. Set this value to true to set the write status to read-only, otherwise set to false.

Valid Values: true | false

Type: Boolean

Required: No

RequesterPays

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.

Note

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.

Valid Values: true | false

Type: Boolean

Required: No

Role

The ARN of the AWS Identity and Access Management (IAM) role that an S3 File Gateway assumes when it accesses the underlying storage.

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Pattern: ^arn:(aws(|-cn|-us-gov|-iso[A-Za-z0-9_-]*)):iam::([0-9]+):role/(\S+)$

Required: Yes

Squash

A value that maps a user to anonymous user.

Valid values 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.

Type: String

Length Constraints: Minimum length of 5. Maximum length of 15.

Required: No

Tags

A list of up to 50 tags that can be assigned to the NFS file share. Each tag is a key-value pair.

Valid characters for key and value are letters, spaces, and numbers representable in UTF-8 format, and the following special characters: + - = . _ : / @. The maximum length of a tag's key is 128 characters, and the maximum length for a tag's value is 256.

Type: Array of Tag objects

Required: No

VPCEndpointDNSName

Specifies the DNS name for the VPC endpoint that the NFS file share uses to connect to Amazon S3.

Note

This parameter is required for NFS file shares that connect to Amazon S3 through a VPC endpoint, a VPC access point, or an access point alias that points to a VPC access point.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Pattern: ^(([a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z0-9\-]*[A-Za-z0-9])$
