IAM / Client / update_role

update_role¶

IAM.Client.update_role(**kwargs)¶

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

response = client.update_role(
    RoleName='string',
    Description='string',
    MaxSessionDuration=123
)

Parameters:

RoleName (string) –
[REQUIRED]

The name of the role that you want to modify.
Description (string) – The new description that you want to apply to the specified role.
MaxSessionDuration (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 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 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.

Note
IAM role credentials provided by Amazon EC2 instances assigned to the role are not subject to the specified maximum session duration.
