Implements IConstruct, IDependable, IInspectable

A CloudFormation AWS::Transfer::Server.

Instantiates an auto-scaling virtual server based on the selected file transfer protocol in AWS . When you make updates to your file transfer protocol-enabled server or when you work with users, use the service-generated ServerId property that is assigned to the newly created server.

  • 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.


domain?

Type: string (optional)

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


endpointDetails?

Type: IResolvable | EndpointDetailsProperty (optional)

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.


endpointType?

Type: string (optional)

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.


identityProviderDetails?

Type: IResolvable | IdentityProviderDetailsProperty (optional)

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. Not required when IdentityProviderType is set to SERVICE_MANAGED .


identityProviderType?

Type: string (optional)

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.


loggingRole?

Type: string (optional)

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 EFSevents.

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


postAuthenticationLoginBanner?

Type: string (optional)

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.


preAuthenticationLoginBanner?

Type: string (optional)

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.


protocolDetails?

Type: IResolvable | ProtocolDetailsProperty (optional)

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


protocols?

Type: string[] (optional)

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 AWS 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


securityPolicyName?

Type: string (optional)

Specifies the name of the security policy that is attached to the server.


structuredLogDestinations?

Type: string[] (optional)

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


tags?

Type: CfnTag[] (optional)

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


workflowDetails?

Type: IResolvable | WorkflowDetailsProperty (optional)

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.

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

  • path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).


addDependency(target)

public addDependency(target: CfnResource): void

Parameters

  • target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.


addDependsOn(target)⚠️

public addDependsOn(target: CfnResource): void

⚠️ Deprecated: use addDependency

Parameters

  • target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.


addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

  • key string
  • value any

Add a value to the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)


addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

  • path string — - The path of the property, you can use dot notation to override values in complex types.
  • value any — - The value.

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.


addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

  • propertyPath string — The path to the property.

Adds an override that deletes the value of a property from the resource definition.


addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

  • propertyPath string — The path of the property.
  • value any — The value.

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).


applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

  • policy RemovalPolicy
  • options RemovalPolicyOptions

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

See also: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options


getAtt(attributeName, typeHint?)

public getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference

Parameters

  • attributeName string — The name of the attribute.
  • typeHint ResolutionTypeHint

Returns

  • Reference

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.


getMetadata(key)

public getMetadata(key: string): any

Parameters

  • key string

Returns

  • any

Retrieve a value value from the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)


inspect(inspector)

public inspect(inspector: TreeInspector): void

Parameters

  • inspector TreeInspector — - tree inspector to collect and process attributes.

Examines the CloudFormation resource and discloses attributes.


obtainDependencies()

public obtainDependencies(): Stack &#124; CfnResource[]

Returns

Overrides the auto-generated logical ID with a specific ID.


removeDependency(target)

public removeDependency(target: CfnResource): void

Parameters

  • target CfnResource

Indicates that this resource no longer depends on another resource.

This can be used for resources across stacks (including nested stacks) and the dependency will automatically be removed from the relevant scope.
