API Reference (API Version 2010-05-08)

UpdateRole

Updates the description or maximum session duration setting of a role.

Request Parameters

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

Description

The new description that you want to apply to the specified role.

Type: String

Length Constraints: Maximum length of 1000.

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

Required: No

MaxSessionDuration

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 maximum of one hour is applied. This setting can have a value from 1 hour to 12 hours.

Anyone who assumes the role from the AWS CLI or API can use the DurationSeconds API parameter or the duration-seconds 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* 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.
