A CloudFormation AWS::Transfer::User.

The AWS::Transfer::User resource creates a user and associates them with an existing 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 session policy, and assign metadata with tags that can be used to group and search for users.

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as transfer from '@aws-cdk/aws-transfer';
const cfnUser = new transfer.CfnUser(this, 'MyCfnUser', {
  role: 'role',
  serverId: 'serverId',
  userName: 'userName',

  // the properties below are optional
  homeDirectory: 'homeDirectory',
  homeDirectoryMappings: [{
    entry: 'entry',
    target: 'target',
  }],
  homeDirectoryType: 'homeDirectoryType',
  policy: 'policy',
  posixProfile: {
    gid: 123,
    uid: 123,

    // the properties below are optional
    secondaryGids: [123],
  },
  sshPublicKeys: ['sshPublicKeys'],
  tags: [{
    key: 'key',
    value: 'value',
  }],
});

role

Type: string

The Amazon Resource Name (ARN) of the AWS 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.

serverId

Type: string

A system-assigned unique identifier for a server instance.

This is the specific server that you added your user to.

userName

Type: string

A unique string that identifies a user and is associated with a 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.

homeDirectory?

Type: string (optional)

The landing directory (folder) for a user when they log in to the server using the client.

A HomeDirectory example is /bucket_name/home/mydirectory .

homeDirectoryMappings?

Type: IResolvable | IResolvable | HomeDirectoryMapEntryProperty[] (optional)

Logical directory mappings that specify what Amazon S3 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 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.

'[ { "Entry": "/", "Target": "/bucket3/customized-reports/" } ]'

In most cases, you can use this value instead of the session policy to lock your user down 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, the entry will be ignored. As a workaround, you can use the Amazon S3 API to create 0 byte objects as place holders for your directory. If using the CLI, use the s3api call instead of s3 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?

Type: string (optional)

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 EFS paths as is in their file transfer protocol clients. If you set it LOGICAL , you need to provide mappings in the HomeDirectoryMappings for how you want to make Amazon S3 or Amazon EFS paths visible to your users.

policy?

Type: string (optional)

A session policy for your user so you can use the same IAM role across multiple users.

This policy restricts 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} .

For session 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 session policy, see Example session policy .

For more information, see AssumeRole in the AWS Security Token Service API Reference .

posixProfile?

Type: IResolvable | PosixProfileProperty (optional)

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 System (Amazon EFS) file systems.

The POSIX permissions that are set on files and directories in your file system determine the level of access your users get when transferring files into and out of your Amazon EFS file systems.

sshPublicKeys?

Type: string[] (optional)

Specifies the public key portion of the Secure Shell (SSH) keys stored for the described user.

tags?

Type: CfnTag[] (optional)

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

Tags are metadata attached to users for any purpose.

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

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

Syntactic sugar for addOverride(path, undefined).

addDependsOn(target)

public addDependsOn(target: CfnResource): void

Parameters

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.

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

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).

getAtt(attributeName)

public getAtt(attributeName: string): Reference

Parameters

  • attributeName string — The name of the attribute.

Returns

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.

overrideLogicalId(newLogicalId)

public overrideLogicalId(newLogicalId: string): void

Parameters

  • newLogicalId string — The new logical ID to use for this stack element.

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

toString()

public toString(): string

Returns

  • string

Returns a string representation of this construct.

protected renderProperties(props)

protected renderProperties(props: { [string]: any }): { [string]: any }

Parameters

  • props { [string]: any }

Returns

  • { [string]: any }
