Used by administrators to choose which groups in the directory should have access to upload and download files over the enabled protocols using 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.
Parameters:
-
home_directory(Optional[HomeDirectory], default:None) –The landing directory (folder) for a user when they log in to the server using the client.
A
HomeDirectoryexample is/bucket_name/home/mydirectory.You can use the
HomeDirectoryparameter forHomeDirectoryTypewhen it is set to eitherPATHorLOGICAL. -
home_directory_type(Optional[HomeDirectoryType], default:None) –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 or Amazon EFS path as is in their file transfer protocol clients. If you set it toLOGICAL, you need to provide mappings in theHomeDirectoryMappingsfor how you want to make Amazon S3 or Amazon EFS paths visible to your users.If
HomeDirectoryTypeisLOGICAL, you must provide mappings, using theHomeDirectoryMappingsparameter. If, on the other hand,HomeDirectoryTypeisPATH, you provide an absolute path using theHomeDirectoryparameter. You cannot have bothHomeDirectoryandHomeDirectoryMappingsin your template. -
home_directory_mappings(Optional[HomeDirectoryMappings], default:None) –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
EntryandTargetpair, whereEntryshows how the path is made visible andTargetis the actual Amazon S3 or Amazon EFS path. If you only specify a target, it is displayed as is. You also must ensure that your Identity and Access Management (IAM) role provides access to paths inTarget. This value can be set only whenHomeDirectoryTypeis set to LOGICAL.The following is an
EntryandTargetpair example.[ { "Entry": "/directory1", "Target": "/bucket_name/home/mydirectory" } ]In most cases, you can use this value instead of the session policy to lock down your user to the designated home directory ("
chroot"). To do this, you can setEntryto/and setTargetto theHomeDirectoryparameter value.The following is an
EntryandTargetpair example forchroot.[ { "Entry": "/", "Target": "/bucket_name/home/mydirectory" } ] -
policy(Optional[Policy], default:None) –A session policy for your user so that you can use the same Identity and Access Management (IAM) role across multiple users. This policy scopes down a user's 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 policy applies only when the domain of
ServerIdis Amazon S3. Amazon EFS does not use session policies.For session policies, 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
Policyargument.For an example of a session policy, see Example session policy.
For more information, see AssumeRole in the Security Token Service API Reference.
-
role(Role) –The Amazon Resource Name (ARN) of the Identity and Access Management (IAM) role that controls your users' access to your Amazon S3 bucket or Amazon 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 Amazon 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(ServerId) –A system-assigned unique identifier for a server instance. This is the specific server that you added your user to.
-
external_id(ExternalId) –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 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,ObjectSidIn that command, replace YourGroupName with the name of your Active Directory group.
The regular expression 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: =,.@:/-
Raises:
-
InternalServiceError–This exception is thrown when an error occurs in the Transfer Family service.
-
InvalidRequestException–This exception is thrown when the client submits a malformed request.
-
ResourceExistsException–The requested resource does not exist, or exists in a region other than the one specified for the command.
-
ResourceNotFoundException–This exception is thrown when a resource is not found by the Amazon Web ServicesTransfer Family service.
-
ServiceUnavailableException–The request has failed because the Amazon Web ServicesTransfer Family service is not available.
-
UnknownServiceError–The service returned an error code this client does not model.
