AWS CloudFormation
User Guide (Version )

AWS::IAM::User

Creates a new IAM user for your AWS account.

For information about limitations on the number of IAM users you can create, see Limitations on IAM Entities in the IAM User Guide.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{ "Type" : "AWS::IAM::User", "Properties" : { "Groups" : [ String, ... ], "LoginProfile" : LoginProfile, "ManagedPolicyArns" : [ String, ... ], "Path" : String, "PermissionsBoundary" : String, "Policies" : [ Policy, ... ], "UserName" : String } }

YAML

Type: AWS::IAM::User Properties: Groups: - String LoginProfile: LoginProfile ManagedPolicyArns: - String Path: String PermissionsBoundary: String Policies: - Policy UserName: String

Properties

Groups

A list of groups to which you want to add the user.

Required: No

Type: List of String

Update requires: No interruption

LoginProfile

Creates a password for the specified user, giving the user the ability to access AWS services through the AWS Management Console. For more information about managing passwords, see Managing Passwords in the IAM User Guide.

Required: No

Type: LoginProfile

Update requires: No interruption

ManagedPolicyArns

A list of Amazon Resource Names (ARNs) of the IAM managed policies that you want to attach to the user.

For more information about ARNs, see Amazon Resource Names (ARNs) and AWS Service Namespaces in the AWS General Reference.

Required: No

Type: List of String

Update requires: No interruption

Path

The path for the user name. For more information about paths, see IAM Identifiers in the IAM User Guide.

This parameter is optional. If it is not included, it defaults to a slash (/).

This parameter allows (through its regex pattern) a string of characters consisting of either a forward slash (/) by itself or a string that must begin and end with forward slashes. In addition, it can contain any ASCII character from the ! (\u0021) through the DEL character (\u007F), including most punctuation characters, digits, and upper and lowercased letters.

Required: No

Type: String

Minimum: 1

Maximum: 512

Pattern: (\u002F)|(\u002F[\u0021-\u007F]+\u002F)

Update requires: No interruption

PermissionsBoundary

The ARN of the policy that is used to set the permissions boundary for the user.

Required: No

Type: String

Update requires: No interruption

Policies

Adds or updates an inline policy document that is embedded in the specified IAM user. To view AWS::IAM::User snippets, see Declaring an IAM User Resource.

Important

The name of each policy for a role, user, or group must be unique. If you don't choose unique names, updates to the IAM identity will fail.

For information about limits on the number of inline policies that you can embed in a user, see Limitations on IAM Entities in the IAM User Guide.

Required: No

Type: List of Policy

Update requires: No interruption

UserName

The name of the user to create. Do not include the path in this value.

This parameter allows (per its regex pattern) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-. The user name must be unique within the account. User names are not distinguished by case. For example, you cannot create users named both "John" and "john".

If you don't specify a name, AWS CloudFormation generates a unique physical ID and uses that ID for the user name.

If you specify a name, you must specify the CAPABILITY_NAMED_IAM value to acknowledge your template's capabilities. For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates.

Important

Naming an IAM resource can cause an unrecoverable error if you reuse the same template in multiple Regions. To prevent this, we recommend using Fn::Join and AWS::Region to create a Region-specific name, as in the following example: {"Fn::Join": ["", [{"Ref": "AWS::Region"}, {"Ref": "MyResourceName"}]]}.

Required: No

Type: String

Update requires: Replacement

Return Values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the UserName. For example: mystack-myuser-1CCXAFG2H2U4D.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

Arn

Returns the Amazon Resource Name (ARN) for the specified AWS::IAM::User resource. For example: arn:aws:iam::123456789012:user/mystack-myuser-1CCXAFG2H2U4D.
