[ aws . transfer ]

describe-user

Description

Describes the user assigned to the specific file transfer protocol-enabled server, as identified by its ServerId property.

The response from this call returns the properties of the user associated with the ServerId value that was specified.

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-user
--server-id <value>
--user-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--server-id (string)

A system-assigned unique identifier for a server that has this user assigned.

--user-name (string)

The name of the user assigned to one or more servers. User names are part of the sign-in credentials to use the Amazon Web Services Transfer Family service and perform file transfer tasks.

--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)

A system-assigned unique identifier for a server that has this user assigned.

User -> (structure)

An array containing the properties of the user account for the ServerID value that you specified.

Arn -> (string)

Specifies the unique Amazon Resource Name (ARN) for the user that was requested to be described.

HomeDirectory -> (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 .

HomeDirectoryMappings -> (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 .

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.

(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. 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.

Entry -> (string)

Represents an entry for HomeDirectoryMappings .

Target -> (string)

Represents the map target that is used in a HomeDirectorymapEntry .

HomeDirectoryType -> (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 need to provide mappings in the HomeDirectoryMappings for how you want to make Amazon S3 or EFS paths visible to your users.

Policy -> (string)

A session 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} .

PosixProfile -> (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 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.

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)

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.

SshPublicKeys -> (list)

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

(structure)

Provides information about the public Secure Shell (SSH) key that is associated with a user account for the specific file transfer protocol-enabled server (as identified by ServerId ). The information returned includes the date the key was imported, the public key contents, and the public key ID. A user can store more than one SSH public key associated with their user name on a specific server.

DateImported -> (timestamp)

Specifies the date that the public key was added to the user account.

SshPublicKeyBody -> (string)

Specifies the content of the SSH public key as specified by the PublicKeyId .

SshPublicKeyId -> (string)

Specifies the SshPublicKeyId parameter contains the identifier of the public key.

Tags -> (list)

Specifies the key-value pairs for the user requested. Tag can be used to search for and group users for a variety of purposes.

(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.

UserName -> (string)

Specifies the name of the user that was requested to be described. User names are used for authentication purposes. This is the string that will be used by your user when they log in to your server.
