See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--role-name <value>
[--description <value>]
[--max-session-duration <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--role-name (string)

The name of the role that you want to modify.

--description (string)

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

--max-session-duration (integer)

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 .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
