)
Parameters:

  • scope (Construct) – Scope in which this resource is defined.

  • id (str) – Construct identifier for this resource (unique in its scope).

  • certificate (Optional[str]) – The Amazon Resource Name (ARN) of the AWS Certificate Manager (ACM) certificate. Required when Protocols is set to FTPS . To request a new public certificate, see Request a public certificate in the AWS Certificate Manager User Guide . To import an existing certificate into ACM, see Importing certificates into ACM in the AWS Certificate Manager User Guide . To request a private certificate to use FTPS through private IP addresses, see Request a private certificate in the AWS 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) .. epigraph:: 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 (Optional[str]) – 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.

  • endpoint_details (Union[IResolvable, EndpointDetailsProperty, Dict[str, Any], None]) – 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.

  • endpoint_type (Optional[str]) – 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. .. epigraph:: 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 .

  • identity_provider_details (Union[IResolvable, IdentityProviderDetailsProperty, Dict[str, Any], None]) – 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 .

  • identity_provider_type (Optional[str]) – 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.

  • logging_role (Optional[str]) – 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.

  • post_authentication_login_banner (Optional[str]) – Specifies a string to display when users connect to a server. This string is displayed after the user authenticates. .. epigraph:: The SFTP protocol does not support post-authentication display banners.

  • pre_authentication_login_banner (Optional[str]) – 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.

  • protocol_details (Union[IResolvable, ProtocolDetailsProperty, Dict[str, Any], None]) – 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 (Optional[Sequence[str]]) – 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 .. epigraph:: - 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

  • s3_storage_options (Union[IResolvable, S3StorageOptionsProperty, Dict[str, Any], None]) – Specifies whether or not performance for your Amazon S3 directories is optimized. 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.

  • security_policy_name (Optional[str]) – Specifies the name of the security policy for the server.

  • structured_log_destinations (Optional[Sequence[str]]) – 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 (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – Key-value pairs that can be used to group and search for servers.

  • workflow_details (Union[IResolvable, WorkflowDetailsProperty, Dict[str, Any], None]) – 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.

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:

path (str) – The path of the value to delete.

Return type:

None

add_dependency(target)

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.

Parameters:

target (CfnResource) –

Return type:

None

add_depends_on(target)

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

Parameters:

target (CfnResource) –

Deprecated:

use addDependency

Stability:

deprecated

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

  • key (str) –

  • value (Any) –

See:

Return type:

None

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.

add_override(path, 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:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"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.

Parameters:

  • path (str) –

    • The path of the property, you can use dot notation to override values in complex types. Any intermediate keys will be created as needed.

  • value (Any) –

    • The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

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

Parameters:

property_path (str) – The path to the property.

Return type:

None

add_property_override(property_path, value)

Adds an override to a resource property.

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

Parameters:

  • property_path (str) – The path of the property.

  • value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

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:

Parameters:

  • policy (Optional[RemovalPolicy]) –

  • apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true

  • default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resource, please consult that specific resource’s documentation.

See:

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

Return type:

None

get_att(attribute_name, type_hint=None)

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.

Parameters:

  • attribute_name (str) – The name of the attribute.

  • type_hint (Optional[ResolutionTypeHint]) –

Static Methods

classmethod is_cfn_element(x)

Returns true if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of instanceof to allow stack elements from different versions of this library to be included in the same stack.

Parameters:

x (Any) –

Return type:

bool

Returns:

The construct as a stack element or undefined if it is not a stack element.

classmethod is_cfn_resource(x)

Check whether the given object is a CfnResource.

Parameters:

x (Any) –

Return type:

bool

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:

x (Any) – Any object.

Return type:

bool

Returns:

true if x is an object created from a class which extends Construct.

EndpointDetailsProperty

class CfnServer.EndpointDetailsProperty(*, address_allocation_ids=None, security_group_ids=None, subnet_ids=None, vpc_endpoint_id=None, vpc_id=None)

Bases: object

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.

Parameters:

  • address_allocation_ids (Optional[Sequence[str]]) – A list of address allocation IDs that are required to attach an Elastic IP address to your server’s endpoint. An address allocation ID corresponds to the allocation ID of an Elastic IP address. This value can be retrieved from the allocationId field from the Amazon EC2 Address data type. One way to retrieve this value is by calling the EC2 DescribeAddresses API. This parameter is optional. Set this parameter if you want to make your VPC endpoint public-facing. For details, see Create an internet-facing endpoint for your server . .. epigraph:: This property can only be set as follows: - EndpointType must be set to VPC - The Transfer Family server must be offline. - You cannot set this parameter for Transfer Family servers that use the FTP protocol. - The server must already have SubnetIds populated ( SubnetIds and AddressAllocationIds cannot be updated simultaneously). - AddressAllocationIds can’t contain duplicates, and must be equal in length to SubnetIds . For example, if you have three subnet IDs, you must also specify three address allocation IDs. - Call the UpdateServer API to set or change this parameter.

  • security_group_ids (Optional[Sequence[str]]) – A list of security groups IDs that are available to attach to your server’s endpoint. .. epigraph:: This property can only be set when EndpointType is set to VPC . You can edit the SecurityGroupIds property in the UpdateServer API only if you are changing the EndpointType from PUBLIC or VPC_ENDPOINT to VPC . To change security groups associated with your server’s VPC endpoint after creation, use the Amazon EC2 ModifyVpcEndpoint API.

  • subnet_ids (Optional[Sequence[str]]) – A list of subnet IDs that are required to host your server endpoint in your VPC. .. epigraph:: This property can only be set when EndpointType is set to VPC .

class CfnServer.IdentityProviderDetailsProperty(*, directory_id=None, function=None, invocation_role=None, sftp_authentication_methods=None, url=None)

Bases: object

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 .

Parameters:

  • directory_id (Optional[str]) – The identifier of the AWS Directory Service directory that you want to use as your identity provider.

  • function (Optional[str]) – The ARN for a Lambda function to use for the Identity provider.

  • invocation_role (Optional[str]) – This parameter is only applicable if your IdentityProviderType is API_GATEWAY . Provides the type of InvocationRole used to authenticate the user account.

  • sftp_authentication_methods (Optional[str]) – For SFTP-enabled servers, and for custom identity providers only , you can specify whether to authenticate using a password, SSH key pair, or both. - PASSWORD - users must provide their password to connect. - PUBLIC_KEY - users must provide their private key to connect. - PUBLIC_KEY_OR_PASSWORD - users can authenticate with either their password or their key. This is the default value. - PUBLIC_KEY_AND_PASSWORD - users must provide both their private key and their password to connect. The server checks the key first, and then if the key is valid, the system prompts for a password. If the private key provided does not match the public key that is stored, authentication fails.

  • url (Optional[str]) – Provides the location of the service endpoint used to authenticate users.

ProtocolDetailsProperty

class CfnServer.ProtocolDetailsProperty(*, as2_transports=None, passive_ip=None, set_stat_option=None, tls_session_resumption_mode=None)

Bases: object

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.

Parameters:

  • as2_transports (Optional[Sequence[str]]) – List of As2Transport objects.

  • passive_ip (Optional[str]) – Indicates passive mode, for FTP and FTPS protocols. Enter a single IPv4 address, such as the public IP address of a firewall, router, or load balancer. For example: aws transfer update-server --protocol-details PassiveIp=0.0.0.0 Replace 0.0.0.0 in the example above with the actual IP address you want to use. .. epigraph:: If you change the PassiveIp value, you must stop and then restart your Transfer Family server for the change to take effect. For details on using passive mode (PASV) in a NAT environment, see Configuring your FTPS server behind a firewall or NAT with AWS Transfer Family . Special values The AUTO and 0.0.0.0 are special values for the PassiveIp parameter. The value PassiveIp=AUTO is assigned by default to FTP and FTPS type servers. In this case, the server automatically responds with one of the endpoint IPs within the PASV response. PassiveIp=0.0.0.0 has a more unique application for its usage. For example, if you have a High Availability (HA) Network Load Balancer (NLB) environment, where you have 3 subnets, you can only specify a single IP address using the PassiveIp parameter. This reduces the effectiveness of having High Availability. In this case, you can specify PassiveIp=0.0.0.0 . This tells the client to use the same IP address as the Control connection and utilize all AZs for their connections. Note, however, that not all FTP clients support the PassiveIp=0.0.0.0 response. FileZilla and WinSCP do support it. If you are using other clients, check to see if your client supports the PassiveIp=0.0.0.0 response.

  • set_stat_option (Optional[str]) – Use the SetStatOption to ignore the error that is generated when the client attempts to use SETSTAT on a file you are uploading to an S3 bucket. Some SFTP file transfer clients can attempt to change the attributes of remote files, including timestamp and permissions, using commands, such as SETSTAT when uploading the file. However, these commands are not compatible with object storage systems, such as Amazon S3. Due to this incompatibility, file uploads from these clients can result in errors even when the file is otherwise successfully uploaded. Set the value to ENABLE_NO_OP to have the Transfer Family server ignore the SETSTAT command, and upload files without needing to make any changes to your SFTP client. While the SetStatOption ENABLE_NO_OP setting ignores the error, it does generate a log entry in Amazon CloudWatch Logs, so you can determine when the client is making a SETSTAT call. .. epigraph:: If you want to preserve the original timestamp for your file, and modify other file attributes using SETSTAT , you can use Amazon EFS as backend storage with Transfer Family.

  • tls_session_resumption_mode (Optional[str]) – A property used with Transfer Family servers that use the FTPS protocol. TLS Session Resumption provides a mechanism to resume or share a negotiated secret key between the control and data connection for an FTPS session. TlsSessionResumptionMode determines whether or not the server resumes recent, negotiated sessions through a unique session ID. This property is available during CreateServer and UpdateServer calls. If a TlsSessionResumptionMode value is not specified during CreateServer , it is set to ENFORCED by default. - DISABLED : the server does not process TLS session resumption client requests and creates a new TLS session for each request. - ENABLED : the server processes and accepts clients that are performing TLS session resumption. The server doesn’t reject client data connections that do not perform the TLS session resumption client processing. - ENFORCED : the server processes and accepts clients that are performing TLS session resumption. The server rejects client data connections that do not perform the TLS session resumption client processing. Before you set the value to ENFORCED , test your clients. .. epigraph:: Not all FTPS clients perform TLS session resumption. So, if you choose to enforce TLS session resumption, you prevent any connections from FTPS clients that don’t perform the protocol negotiation. To determine whether or not you can use the ENFORCED value, you need to test your clients.

passive_ip

Indicates passive mode, for FTP and FTPS protocols.

Enter a single IPv4 address, such as the public IP address of a firewall, router, or load balancer. For example:

aws transfer update-server --protocol-details PassiveIp=0.0.0.0

Replace 0.0.0.0 in the example above with the actual IP address you want to use. .. epigraph:

If you change the ``PassiveIp`` value, you must stop and then restart your Transfer Family server for the change to take effect.
