Method Details

getCertificate

@Stability(Stable)
@Nullable
default String getCertificate()

The Amazon Resource Name (ARN) of the Certificate Manager (ACM) certificate. Required when Protocols is set to FTPS .

To request a new public certificate, see Request a public certificate in the Certificate Manager User Guide .

To import an existing certificate into ACM, see Importing certificates into ACM in the Certificate Manager User Guide .

To request a private certificate to use FTPS through private IP addresses, see Request a private certificate in the Certificate Manager User Guide .

Certificates with the following cryptographic algorithms and key sizes are supported:

• 2048-bit RSA (RSA_2048)
• 4096-bit RSA (RSA_4096)
• Elliptic Prime Curve 256 bit (EC_prime256v1)
• Elliptic Prime Curve 384 bit (EC_secp384r1)
• Elliptic Prime Curve 521 bit (EC_secp521r1)

The certificate must be a valid SSL/TLS X.509 version 3 certificate with FQDN or IP address specified and information about the issuer.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-certificate

getDomain

@Stability(Stable)
@Nullable
default String getDomain()

Specifies the domain of the storage system that is used for file transfers.

There are two domains available: Amazon Simple Storage Service (Amazon S3) and Amazon Elastic File System (Amazon EFS). The default value is S3.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-domain

getEndpointDetails

@Stability(Stable)
@Nullable
default Object getEndpointDetails()

The virtual private cloud (VPC) endpoint settings that are configured for your server.

When you host your endpoint within your VPC, you can make your endpoint accessible only to resources within your VPC, or you can attach Elastic IP addresses and make your endpoint accessible to clients over the internet. Your VPC's default security groups are automatically assigned to your endpoint.

Returns union: either IResolvable or CfnServer.EndpointDetailsProperty

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-endpointdetails

getEndpointType

@Stability(Stable)
@Nullable
default String getEndpointType()

The type of endpoint that you want your server to use.

You can choose to make your server's endpoint publicly accessible (PUBLIC) or host it inside your VPC. With an endpoint that is hosted in a VPC, you can restrict access to your server and resources only within your VPC or choose to make it internet facing by attaching Elastic IP addresses directly to it.

After May 19, 2021, you won't be able to create a server using EndpointType=VPC_ENDPOINT in your AWS account if your account hasn't already done so before May 19, 2021. If you have already created servers with EndpointType=VPC_ENDPOINT in your AWS account on or before May 19, 2021, you will not be affected. After this date, use EndpointType = VPC .

For more information, see Discontinuing the use of VPC_ENDPOINT .

It is recommended that you use VPC as the EndpointType . With this endpoint type, you have the option to directly associate up to three Elastic IPv4 addresses (BYO IP included) with your server's endpoint and use VPC security groups to restrict traffic by the client's public IP address. This is not possible with EndpointType set to VPC_ENDPOINT .

getIdentityProviderDetails

@Stability(Stable)
@Nullable
default Object getIdentityProviderDetails()

Required when IdentityProviderType is set to AWS_DIRECTORY_SERVICE , AWS _LAMBDA or API_GATEWAY .

Accepts an array containing all of the information required to use a directory in AWS_DIRECTORY_SERVICE or invoke a customer-supplied authentication API, including the API Gateway URL. Cannot be specified when IdentityProviderType is set to SERVICE_MANAGED .

Returns union: either IResolvable or CfnServer.IdentityProviderDetailsProperty

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-identityproviderdetails

getIdentityProviderType

@Stability(Stable)
@Nullable
default String getIdentityProviderType()

The mode of authentication for a server.

The default value is SERVICE_MANAGED , which allows you to store and access user credentials within the AWS Transfer Family service.

Use AWS_DIRECTORY_SERVICE to provide access to Active Directory groups in AWS Directory Service for Microsoft Active Directory or Microsoft Active Directory in your on-premises environment or in AWS using AD Connector. This option also requires you to provide a Directory ID by using the IdentityProviderDetails parameter.

Use the API_GATEWAY value to integrate with an identity provider of your choosing. The API_GATEWAY setting requires you to provide an Amazon API Gateway endpoint URL to call for authentication by using the IdentityProviderDetails parameter.

Use the AWS_LAMBDA value to directly use an AWS Lambda function as your identity provider. If you choose this value, you must specify the ARN for the Lambda function in the Function parameter for the IdentityProviderDetails data type.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-identityprovidertype

getIpAddressType

@Stability(Stable)
@Nullable
default String getIpAddressType()

Specifies whether to use IPv4 only, or to use dual-stack (IPv4 and IPv6) for your AWS Transfer Family endpoint.

The default value is IPV4 .

The IpAddressType parameter has the following limitations:

• It cannot be changed while the server is online. You must stop the server before modifying this parameter.
• It cannot be updated to DUALSTACK if the server has AddressAllocationIds specified. > When using DUALSTACK as the IpAddressType , you cannot set the AddressAllocationIds parameter for the EndpointDetails for the server.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-ipaddresstype

getLoggingRole

@Stability(Stable)
@Nullable
default String getLoggingRole()

The Amazon Resource Name (ARN) of the AWS Identity and Access Management (IAM) role that allows a server to turn on Amazon CloudWatch logging for Amazon S3 or Amazon EFS events.

When set, you can view user activity in your CloudWatch logs.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-loggingrole

getPostAuthenticationLoginBanner

@Stability(Stable)
@Nullable
default String getPostAuthenticationLoginBanner()

Specifies a string to display when users connect to a server. This string is displayed after the user authenticates.

The SFTP protocol does not support post-authentication display banners.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-postauthenticationloginbanner

getPreAuthenticationLoginBanner

@Stability(Stable)
@Nullable
default String getPreAuthenticationLoginBanner()

Specifies a string to display when users connect to a server.

This string is displayed before the user authenticates. For example, the following banner displays details about using the system:

This system is for the use of authorized users only. Individuals using this computer system without authority, or in excess of their authority, are subject to having all of their activities on this system monitored and recorded by system personnel.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-preauthenticationloginbanner

getProtocolDetails

@Stability(Stable)
@Nullable
default Object getProtocolDetails()

The protocol settings that are configured for your server.

• To indicate passive mode (for FTP and FTPS protocols), use the PassiveIp parameter. Enter a single dotted-quad IPv4 address, such as the external IP address of a firewall, router, or load balancer.
• To ignore the error that is generated when the client attempts to use the SETSTAT command on a file that you are uploading to an Amazon S3 bucket, use the SetStatOption parameter. To have the AWS Transfer Family server ignore the SETSTAT command and upload files without needing to make any changes to your SFTP client, set the value to ENABLE_NO_OP . If you set the SetStatOption parameter to ENABLE_NO_OP , Transfer Family generates a log entry to Amazon CloudWatch Logs, so that you can determine when the client is making a SETSTAT call.
• To determine whether your AWS Transfer Family server resumes recent, negotiated sessions through a unique session ID, use the TlsSessionResumptionMode parameter.
• As2Transports indicates the transport method for the AS2 messages. Currently, only HTTP is supported.

The Protocols parameter is an array of strings.

Allowed values : One or more of SFTP , FTPS , FTP , AS2

Returns union: either IResolvable or CfnServer.ProtocolDetailsProperty

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-protocoldetails

getProtocols

@Stability(Stable)
@Nullable
default List<String> getProtocols()

Specifies the file transfer protocol or protocols over which your file transfer protocol client can connect to your server's endpoint.

The available protocols are:

• SFTP (Secure Shell (SSH) File Transfer Protocol): File transfer over SSH
• FTPS (File Transfer Protocol Secure): File transfer with TLS encryption
• FTP (File Transfer Protocol): Unencrypted file transfer
• AS2 (Applicability Statement 2): used for transporting structured business-to-business data

• If you select FTPS , you must choose a certificate stored in Certificate Manager (ACM) which is used to identify your server when clients connect to it over FTPS.
• If Protocol includes either FTP or FTPS , then the EndpointType must be VPC and the IdentityProviderType must be either AWS_DIRECTORY_SERVICE , AWS_LAMBDA , or API_GATEWAY .
• If Protocol includes FTP , then AddressAllocationIds cannot be associated.
• If Protocol is set only to SFTP , the EndpointType can be set to PUBLIC and the IdentityProviderType can be set any of the supported identity types: SERVICE_MANAGED , AWS_DIRECTORY_SERVICE , AWS_LAMBDA , or API_GATEWAY .
• If Protocol includes AS2 , then the EndpointType must be VPC , and domain must be Amazon S3.

The Protocols parameter is an array of strings.

Allowed values : One or more of SFTP , FTPS , FTP , AS2

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-protocols

getS3StorageOptions

@Stability(Stable)
@Nullable
default Object getS3StorageOptions()

Specifies whether or not performance for your Amazon S3 directories is optimized.

• If using the console, this is enabled by default.
• If using the API or CLI, this is disabled by default.

By default, home directory mappings have a TYPE of DIRECTORY . If you enable this option, you would then need to explicitly set the HomeDirectoryMapEntry Type to FILE if you want a mapping to have a file target.

Returns union: either IResolvable or CfnServer.S3StorageOptionsProperty

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-s3storageoptions

getSecurityPolicyName

@Stability(Stable)
@Nullable
default String getSecurityPolicyName()

Specifies the name of the security policy for the server.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-securitypolicyname

getStructuredLogDestinations

@Stability(Stable)
@Nullable
default List<String> getStructuredLogDestinations()

Specifies the log groups to which your server logs are sent.

To specify a log group, you must provide the ARN for an existing log group. In this case, the format of the log group is as follows:

arn:aws:logs:region-name:amazon-account-id:log-group:log-group-name:*

For example, arn:aws:logs:us-east-1:111122223333:log-group:mytestgroup:*

If you have previously specified a log group for a server, you can clear it, and in effect turn off structured logging, by providing an empty value for this parameter in an update-server call. For example:

update-server --server-id s-1234567890abcdef0 --structured-log-destinations

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-structuredlogdestinations

getTags

@Stability(Stable)
@Nullable
default List<CfnTag> getTags()

Key-value pairs that can be used to group and search for servers.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-transfer-server.html#cfn-transfer-server-tags

getWorkflowDetails

@Stability(Stable)
@Nullable
default Object getWorkflowDetails()

Specifies the workflow ID for the workflow to assign and the execution role that's used for executing the workflow.

In addition to a workflow to execute when a file is uploaded completely, WorkflowDetails can also contain a workflow ID (and execution role) for a workflow to execute on partial upload. A partial upload occurs when a file is open when the session disconnects.

Returns union: either IResolvable or CfnServer.WorkflowDetailsProperty
