Transfer

create_access(external_id, role, server_id)
create_access(external_id, role, server_id, params::Dict{String,<:Any})

Used by administrators to choose which groups in the directory should have access to upload and download files over the enabled protocols using AWS Transfer Family. For example, a Microsoft Active Directory might contain 50,000 users, but only a small fraction might need the ability to transfer files to the server. An administrator can use CreateAccess to limit the access to the correct set of users who need this ability.

Arguments

• external_id: A unique identifier that is required to identify specific groups within your directory. The users of the group that you associate have access to your Amazon S3 or Amazon EFS resources over the enabled protocols using AWS Transfer Family. If you know the group name, you can view the SID values by running the following command using Windows PowerShell. Get-ADGroup -Filter {samAccountName -like "YourGroupName*"} -Properties * | Select SamaccountName,ObjectSid In that command, replace YourGroupName with the name of your Active Directory group. The regex used to validate this parameter is a string of characters consisting of uppercase and lowercase alphanumeric characters with no spaces. You can also include underscores or any of the following characters: =,.@:/-
• role: Specifies the IAM role that controls your users' access to your Amazon S3 bucket or EFS file system. The policies attached to this role determine the level of access that you want to provide your users when transferring files into and out of your Amazon S3 bucket or EFS file system. The IAM role should also contain a trust relationship that allows the server to access your resources when servicing your users' transfer requests.
• server_id: A system-assigned unique identifier for a server instance. This is the specific server that you added your user to.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "HomeDirectory": The landing directory (folder) for a user when they log in to the server using the client. A HomeDirectory example is /directory_name/home/mydirectory.
• "HomeDirectoryMappings": Logical directory mappings that specify what Amazon S3 or Amazon EFS paths and keys should be visible to your user and how you want to make them visible. You must specify the Entry and Target pair, where Entry shows how the path is made visible and Target is the actual Amazon S3 or Amazon EFS path. If you only specify a target, it will be displayed as is. You also must ensure that your AWS Identity and Access Management (IAM) role provides access to paths in Target. This value can only be set when HomeDirectoryType is set to LOGICAL. The following is an Entry and Target pair example. [ { "Entry": "your-personal-report.pdf", "Target": "/bucket3/customized-reports/{transfer:UserName}.pdf" } ] In most cases, you can use this value instead of the scope-down policy to lock down your user to the designated home directory ("chroot"). To do this, you can set Entry to / and set Target to the HomeDirectory parameter value. The following is an Entry and Target pair example for chroot. [ { "Entry": "/", "Target": "/bucket_name/home/mydirectory" } ] If the target of a logical directory entry does not exist in Amazon S3 or Amazon EFS, the entry will be ignored. As a workaround, you can use the Amazon S3 API or EFS API to create 0-byte objects as place holders for your directory. If using the AWS CLI, use the s3api or efsapi call instead of s3 or efs so you can use the put-object operation. For example, you can use the following. aws s3api put-object –bucket bucketname –key path/to/folder/ The end of the key name must end in a / for it to be considered a folder. Required: No
• "HomeDirectoryType": The type of landing directory (folder) that you want your users' home directory to be when they log in to the server. If you set it to PATH, the user will see the absolute Amazon S3 bucket paths as is in their file transfer protocol clients. If you set it LOGICAL, you must provide mappings in the HomeDirectoryMappings for how you want to make Amazon S3 paths visible to your users.
• "Policy": A scope-down policy for your user so that you can use the same IAM role across multiple users. This policy scopes down user access to portions of their Amazon S3 bucket. Variables that you can use inside this policy include {Transfer:UserName}, {Transfer:HomeDirectory}, and {Transfer:HomeBucket}. This only applies when domain of ServerId is S3. Amazon EFS does not use scope down policy. For scope-down policies, AWS Transfer Family stores the policy as a JSON blob, instead of the Amazon Resource Name (ARN) of the policy. You save the policy as a JSON blob and pass it in the Policy argument. For an example of a scope-down policy, see Example scope-down policy. For more information, see AssumeRole in the AWS Security Token Service API Reference.
• "PosixProfile":

create_server()
create_server(params::Dict{String,<:Any})

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.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "Certificate": 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 (RSA2048) 4096-bit RSA (RSA4096) Elliptic Prime Curve 256 bit (ECprime256v1) Elliptic Prime Curve 384 bit (ECsecp384r1) 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": 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. After the server is created, the domain cannot be changed.
• "EndpointDetails": The virtual private cloud (VPC) endpoint settings that are configured for your server. When you host your endpoint within your VPC, you can make it accessible only to resources within your VPC, or you can attach Elastic IP addresses and make it accessible to clients over the internet. Your VPC's default security groups are automatically assigned to your endpoint.
• "EndpointType": 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 March 31, 2021, you won't be able to create a server using EndpointType=VPCENDPOINT in your AWS account if your account hasn't already done so before March 31, 2021. If you have already created servers with EndpointType=VPCENDPOINT in your AWS account on or before March 31, 2021, you will not be affected. After this date, use EndpointType=VPC. For more information, see https://docs.aws.amazon.com/transfer/latest/userguide/create-server-in-vpc.html#deprecate-vp c-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.
• "HostKey": The RSA private key as generated by the ssh-keygen -N "" -m PEM -f my-new-server-key command. If you aren't planning to migrate existing users from an existing SFTP-enabled server to a new server, don't update the host key. Accidentally changing a server's host key can be disruptive. For more information, see Change the host key for your SFTP-enabled server in the AWS Transfer Family User Guide.
• "IdentityProviderDetails": Required when IdentityProviderType is set to AWSDIRECTORYSERVICE or APIGATEWAY. Accepts an array containing all of the information required to use a directory in AWSDIRECTORYSERVICE or invoke a customer-supplied authentication API, including the API Gateway URL. Not required when IdentityProviderType is set to SERVICEMANAGED.
• "IdentityProviderType": Specifies the mode of authentication for a server. The default value is SERVICEMANAGED, which allows you to store and access user credentials within the AWS Transfer Family service. Use AWSDIRECTORYSERVICE to provide access to Active Directory groups in AWS Managed Active Directory or Microsoft Active Directory in your on-premises environment or in AWS using AD Connectors. This option also requires you to provide a Directory ID using the IdentityProviderDetails parameter. Use the APIGATEWAY value to integrate with an identity provider of your choosing. The API_GATEWAY setting requires you to provide an API Gateway endpoint URL to call for authentication using the IdentityProviderDetails parameter.
• "LoggingRole": Allows the service to write your users' activity to your Amazon CloudWatch logs for monitoring and auditing purposes.
• "Protocols": 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 If you select FTPS, you must choose a certificate stored in AWS Certificate Manager (ACM) which will be 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 AWSDIRECTORYSERVICE or APIGATEWAY. 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 to SERVICEMANAGED.
• "SecurityPolicyName": Specifies the name of the security policy that is attached to the server.
• "Tags": Key-value pairs that can be used to group and search for servers.

create_user(role, server_id, user_name)
create_user(role, server_id, user_name, params::Dict{String,<:Any})

Creates a user and associates them with an existing file transfer protocol-enabled server. You can only create and associate users with servers that have the IdentityProviderType set to SERVICE_MANAGED. Using parameters for CreateUser, you can specify the user name, set the home directory, store the user's public key, and assign the user's AWS Identity and Access Management (IAM) role. You can also optionally add a scope-down policy, and assign metadata with tags that can be used to group and search for users.

Arguments

• role: Specifies the IAM role that controls your users' access to your Amazon S3 bucket or EFS file system. The policies attached to this role will determine the level of access you want to provide your users when transferring files into and out of your Amazon S3 bucket or EFS file system. The IAM role should also contain a trust relationship that allows the server to access your resources when servicing your users' transfer requests.
• server_id: A system-assigned unique identifier for a server instance. This is the specific server that you added your user to.
• user_name: A unique string that identifies a user and is associated with a as specified by the ServerId. This user name must be a minimum of 3 and a maximum of 100 characters long. The following are valid characters: a-z, A-Z, 0-9, underscore '_', hyphen '-', period '.', and at sign '@'. The user name can't start with a hyphen, period, or at sign.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "HomeDirectoryMappings": Logical directory mappings that specify what Amazon S3 or EFS paths and keys should be visible to your user and how you want to make them visible. You will need to specify the Entry and Target pair, where Entry shows how the path is made visible and Target is the actual Amazon S3 or EFS path. If you only specify a target, it will be displayed as is. You will need to also make sure that your IAM role provides access to paths in Target. This value can only be set when HomeDirectoryType is set to LOGICAL. The following is an Entry and Target pair example.

To do this, you can set Entry to / and set Target to the HomeDirectory parameter value. The following is an Entry and Target pair example for chroot. [ { "Entry": "/", "Target": "/bucket_name/home/mydirectory" } ] If the target of a logical directory entry does not exist in Amazon S3 or EFS, the entry will be ignored. As a workaround, you can use the Amazon S3 API or EFS API to create 0 byte objects as place holders for your directory. If using the CLI, use the s3api or efsapi call instead of s3 or efs so you can use the put-object operation. For example, you use the following: aws s3api put-object –bucket bucketname –key path/to/folder/. Make sure that the end of the key name ends in a / for it to be considered a folder.

The users of the group that you associate have access to your Amazon S3 or Amazon EFS resources over the enabled protocols using AWS Transfer Family. If you know the group name, you can view the SID values by running the following command using Windows PowerShell. Get-ADGroup -Filter {samAccountName -like "YourGroupName*"} -Properties * | Select SamaccountName,ObjectSid In that command, replace YourGroupName with the name of your Active Directory group. The regex used to validate this parameter is a string of characters consisting of uppercase and lowercase alphanumeric characters with no spaces. You can also include underscores or any of the following characters: =,.@:/-
• server_id: A system-assigned unique identifier for a server instance. This is the specific server that you added your user to.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "HomeDirectory": The landing directory (folder) for a user when they log in to the server using the client. A HomeDirectory example is /directory_name/home/mydirectory.

You must specify the Entry and Target pair, where Entry shows how the path is made visible and Target is the actual Amazon S3 or Amazon EFS path. If you only specify a target, it will be displayed as is. You also must ensure that your AWS Identity and Access Management (IAM) role provides access to paths in Target. This value can only be set when HomeDirectoryType is set to LOGICAL. The following is an Entry and Target pair example. [ { "Entry": "your-personal-report.pdf", "Target": "/bucket3/customized-reports/{transfer:UserName}.pdf" } ] In most cases, you can use this value instead of the scope-down policy to lock down your user to the designated home directory ("chroot"). To do this, you can set Entry to / and set Target to the HomeDirectory parameter value. The following is an Entry and Target pair example for chroot. [ { "Entry": "/", "Target": "/bucket_name/home/mydirectory" } ] If the target of a logical directory entry does not exist in Amazon S3 or Amazon EFS, the entry will be ignored. As a workaround, you can use the Amazon S3 API or EFS API to create 0-byte objects as place holders for your directory. If using the AWS CLI, use the s3api or efsapi call instead of s3 or efs so you can use the put-object operation. For example, you can use the following. aws s3api put-object –bucket bucketname –key path/to/folder/ The end of the key name must end in a / for it to be considered a folder. Required: No
• "HomeDirectoryType": The type of landing directory (folder) that you want your users' home directory to be when they log in to the server. If you set it to PATH, the user will see the absolute Amazon S3 bucket paths as is in their file transfer protocol clients. If you set it LOGICAL, you must provide mappings in the HomeDirectoryMappings for how you want to make Amazon S3 paths visible to your users.
• "Policy": A scope-down policy for your user so that you can use the same IAM role across multiple users. This policy scopes down user access to portions of their Amazon S3 bucket. Variables that you can use inside this policy include {Transfer:UserName}, {Transfer:HomeDirectory}, and {Transfer:HomeBucket}. This only applies when domain of ServerId is S3. Amazon EFS does not use scope down policy. For scope-down policies, AWS Transfer Family stores the policy as a JSON blob, instead of the Amazon Resource Name (ARN) of the policy. You save the policy as a JSON blob and pass it in the Policy argument. For an example of a scope-down policy, see Example scope-down policy. For more information, see AssumeRole in the AWS Security Token Service API Reference.
• "PosixProfile":
• "Role": Specifies the IAM role that controls your users' access to your Amazon S3 bucket or EFS file system. The policies attached to this role determine the level of access that you want to provide your users when transferring files into and out of your Amazon S3 bucket or EFS file system. The IAM role should also contain a trust relationship that allows the server to access your resources when servicing your users' transfer requests.

update_server(server_id)

• server_id: A system-assigned unique identifier for a server instance that the user account is assigned to.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "Certificate": 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 (RSA2048) 4096-bit RSA (RSA4096) Elliptic Prime Curve 256 bit (ECprime256v1) Elliptic Prime Curve 384 bit (ECsecp384r1) 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.
• "EndpointDetails": The virtual private cloud (VPC) endpoint settings that are configured for your server. With a VPC endpoint, you can restrict access to your server to resources only within your VPC. To control incoming internet traffic, you will need to associate one or more Elastic IP addresses with your server's endpoint.
• "EndpointType": 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 March 31, 2021, you won't be able to create a server using EndpointType=VPCENDPOINT in your AWS account if your account hasn't already done so before March 31, 2021. If you have already created servers with EndpointType=VPCENDPOINT in your AWS account on or before March 31, 2021, you will not be affected. After this date, use EndpointType=VPC. For more information, see https://docs.aws.amazon.com/transfer/latest/userguide/create-server-in-vpc.html#deprecate-vp c-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.
• "HostKey": The RSA private key as generated by ssh-keygen -N "" -m PEM -f my-new-server-key. If you aren't planning to migrate existing users from an existing server to a new server, don't update the host key. Accidentally changing a server's host key can be disruptive. For more information, see Change the host key for your SFTP-enabled server in the AWS Transfer Family User Guide.
• "IdentityProviderDetails": An array containing all of the information required to call a customer's authentication API method.
• "LoggingRole": Changes the AWS Identity and Access Management (IAM) role that allows Amazon S3 or Amazon EFS events to be logged in Amazon CloudWatch, turning logging on or off.
• "Protocols": 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: Secure Shell (SSH) File Transfer Protocol (SFTP): File transfer over SSH File Transfer Protocol Secure (FTPS): File transfer with TLS encryption File Transfer Protocol (FTP): Unencrypted file transfer If you select FTPS, you must choose a certificate stored in AWS Certificate Manager (ACM) which will be 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 AWSDIRECTORYSERVICE or APIGATEWAY. 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 to SERVICEMANAGED.
• "SecurityPolicyName": Specifies the name of the security policy that is attached to the server.

update_user(server_id, user_name)
update_user(server_id, user_name, params::Dict{String,<:Any})

Assigns new properties to a user. Parameters you pass modify any or all of the following: the home directory, role, and policy for the UserName and ServerId you specify. The response returns the ServerId and the UserName for the updated user.

Arguments

• server_id: A system-assigned unique identifier for a server instance that the user account is assigned to.
• user_name: A unique string that identifies a user and is associated with a server as specified by the ServerId. This user name must be a minimum of 3 and a maximum of 100 characters long. The following are valid characters: a-z, A-Z, 0-9, underscore '_', hyphen '-', period '.', and at sign '@'. The user name can't start with a hyphen, period, or at sign.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "HomeDirectory": Specifies the landing directory (folder) for a user when they log in to the server using their file transfer protocol client. An example is your-Amazon-S3-bucket-name>/home/username.
• "HomeDirectoryMappings": Logical directory mappings that specify what Amazon S3 or Amazon EFS paths and keys should be visible to your user and how you want to make them visible. You will need to specify the "Entry" and "Target" pair, where Entry shows how the path is made visible and Target is the actual Amazon S3 or Amazon EFS path. If you only specify a target, it will be displayed as is. You will need to also make sure that your IAM role provides access to paths in Target. The following is an example. '[ "/bucket2/documentation", { "Entry": "your-personal-report.pdf", "Target": "/bucket3/customized-reports/{transfer:UserName}.pdf" } ]' In most cases, you can use this value instead of the scope-down policy to lock down your user to the designated home directory ("chroot"). To do this, you can set Entry to '/' and set Target to the HomeDirectory parameter value. If the target of a logical directory entry does not exist in Amazon S3 or EFS, the entry will be ignored. As a workaround, you can use the Amazon S3 API or EFS API to create 0-byte objects as place holders for your directory. If using the AWS CLI, use the s3api or efsapi call instead of s3 efs so you can use the put-object operation. For example, you use the following: aws s3api put-object –bucket bucketname –key path/to/folder/. Make sure that the end of the key name ends in a / for it to be considered a folder.
• "HomeDirectoryType": The type of landing directory (folder) you want your users' home directory to be when they log into the server. If you set it to PATH, the user will see the absolute Amazon S3 bucket or EFS paths as is in their file transfer protocol clients. If you set it LOGICAL, you will need to provide mappings in the HomeDirectoryMappings for how you want to make Amazon S3 or EFS paths visible to your users.
• "Policy": Allows you to supply a scope-down policy for your user so you can use the same IAM role across multiple users. The policy scopes down user access to portions of your Amazon S3 bucket. Variables you can use inside this policy include {Transfer:UserName}, {Transfer:HomeDirectory}, and {Transfer:HomeBucket}. For scope-down policies, AWS Transfer Family stores the policy as a JSON blob, instead of the Amazon Resource Name (ARN) of the policy. You save the policy as a JSON blob and pass it in the Policy argument. For an example of a scope-down policy, see Creating a scope-down policy. For more information, see AssumeRole in the AWS Security Token Service API Reference.
• "PosixProfile": Specifies the full POSIX identity, including user ID (Uid), group ID (Gid), and any secondary groups IDs (SecondaryGids), that controls your users' access to your Amazon Elastic File Systems (Amazon EFS). The POSIX permissions that are set on files and directories in your file system determines the level of access your users get when transferring files into and out of your Amazon EFS file systems.
• "Role": The IAM role that controls your users' access to your Amazon S3 bucket. The policies attached to this role determine the level of access you want to provide your users when transferring files into and out of your S3 bucket or buckets. The IAM role should also contain a trust relationship that allows the server to access your resources when servicing your users' transfer requests.
