CreateRole - Amazon Identity and Access Management
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.


Creates a new role for your Amazon Web Services account. For more information about roles, see IAM roles. For information about quotas for role names and the number of roles you can create, see IAM and Amazon STS quotas in the IAM User Guide.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.


The trust relationship policy document that grants an entity permission to assume the role.

In IAM, you must provide a JSON policy that has been converted to a string. However, for Amazon CloudFormation templates formatted in YAML, you can provide the policy in JSON or YAML format. Amazon CloudFormation always converts a YAML policy to JSON format before submitting it to IAM.

The regex pattern used to validate this parameter is a string of characters consisting of the following:

  • Any printable ASCII character ranging from the space character (\u0020) through the end of the ASCII character range

  • The printable characters in the Basic Latin and Latin-1 Supplement character set (through \u00FF)

  • The special characters tab (\u0009), line feed (\u000A), and carriage return (\u000D)

Upon success, the response includes the same trust policy in JSON format.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 131072.

Pattern: [\u0009\u000A\u000D\u0020-\u00FF]+

Required: Yes


A description of the role.

Type: String

Length Constraints: Maximum length of 1000.

Pattern: [\p{L}\p{M}\p{Z}\p{S}\p{N}\p{P}]*

Required: No


The maximum session duration (in seconds) that you want to set for the specified role. If you do not specify a value for this setting, the default value of one hour is applied. This setting can have a value from 1 hour to 12 hours.

Anyone who assumes the role from the Amazon CLI or API can use the DurationSeconds API parameter or the duration-seconds Amazon CLI parameter to request a longer session. The MaxSessionDuration setting determines the maximum duration that can be requested using the DurationSeconds parameter. If users don't specify a value for the DurationSeconds parameter, their security credentials are valid for one hour by default. This applies when you use the AssumeRole* API operations or the assume-role* Amazon CLI operations but does not apply when you use those operations to create a console URL. For more information, see Using IAM roles in the IAM User Guide.

Type: Integer

Valid Range: Minimum value of 3600. Maximum value of 43200.

Required: No


The path to the role. 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.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 512.

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

Required: No


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

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Required: No


The name of the role to create.

IAM user, group, role, and policy names must be unique within the account. Names are not distinguished by case. For example, you cannot create resources named both "MyResource" and "myresource".

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: [\w+=,.@-]+

Required: Yes


A list of tags that you want to attach to the new role. Each tag consists of a key name and an associated value. For more information about tagging, see Tagging IAM resources in the IAM User Guide.


If any one of the tags is invalid or if you exceed the allowed maximum number of tags, then the entire request fails and the resource is not created.

Type: Array of Tag objects

Array Members: Maximum number of 50 items.

Required: No

Response Elements

The following element is returned by the service.


A structure containing details about the new role.

Type: Role object
