[ aws . transfer ]

create-user

Description

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 Amazon Web Services 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.

Options

--home-directory (string)

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 .

--home-directory-type (string)

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.

Possible values:

  • PATH

  • LOGICAL

--home-directory-mappings (list)

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 is displayed as is. You also must ensure that your Amazon Web Services 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 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.

The following is an Entry and Target pair example for chroot .

[ { "Entry:": "/", "Target": "/bucket_name/home/mydirectory" } ]

Note

If the target of a logical directory entry does not exist in Amazon S3 or EFS, the entry is 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.

(structure)

Represents an object that contains entries and targets for HomeDirectoryMappings .

The following is an Entry and Target pair example for chroot .

[ { "Entry:": "/", "Target": "/bucket_name/home/mydirectory" } ]

Note

If the target of a logical directory entry does not exist in Amazon S3 or EFS, the entry is ignored.

Entry -> (string)

Represents an entry for HomeDirectoryMappings .

Target -> (string)

Represents the map target that is used in a HomeDirectorymapEntry .

Shorthand Syntax:

Entry=string,Target=string ...

JSON Syntax:

[
  {
    "Entry": "string",
    "Target": "string"
  }
  ...
]

--policy (string)

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} .

Note

This only applies when domain of ServerId is S3. EFS does not use scope down policy.

For scope-down policies, Amazon Web Services 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 Amazon Web Services Security Token Service API Reference .

--posix-profile (structure)

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

Uid -> (long)

The POSIX user ID used for all EFS operations by this user.

Gid -> (long)

The POSIX group ID used for all EFS operations by this user.

SecondaryGids -> (list)

The secondary POSIX group IDs used for all EFS operations by this user.

(long)

Shorthand Syntax:

Uid=long,Gid=long,SecondaryGids=long,long

JSON Syntax:

{
  "Uid": long,
  "Gid": long,
  "SecondaryGids": [long, ...]
}

--role (string)

Specifies the Amazon Resource Name (ARN) of 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 (string)

A system-assigned unique identifier for a server instance. This is the specific server that you added your user to.

--ssh-public-key-body (string)

The public portion of the Secure Shell (SSH) key used to authenticate the user to the server.

--tags (list)

Key-value pairs that can be used to group and search for users. Tags are metadata attached to users for any purpose.

(structure)

Creates a key-value pair for a specific resource. Tags are metadata that you can use to search for and group a resource for various purposes. You can apply tags to servers, users, and roles. A tag key can take more than one value. For example, to group servers for accounting purposes, you might create a tag called Group and assign the values Research and Accounting to that group.

Key -> (string)

The name assigned to the tag that you create.

Value -> (string)

Contains one or more values that you assigned to the key name you create.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--user-name (string)

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.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output

ServerId -> (string)

The ID of the server that the user is attached to.

UserName -> (string)

A unique string that identifies a user account associated with a server.
