UPDATEASSUMEROLEPOLICY


PDF

Updates the policy that grants an IAM entity permission to assume a role. This
is typically referred to as the "role trust policy". For more information about
roles, see Using roles to delegate permissions and federate identities.


REQUEST PARAMETERS


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

PolicyDocument

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

You must provide policies in JSON format in IAM. However, for AWS CloudFormation
templates formatted in YAML, you can provide the policy in JSON or YAML format.
AWS 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)

Type: String

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

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

Required: Yes

RoleName

The name of the role to update with the new policy.

This parameter allows (through 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: _+=,.@-

Type: String

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

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

Required: Yes


ERRORS


For information about the errors that are common to all actions, see Common
Errors.

LimitExceeded

The request was rejected because it attempted to create resources beyond the
current AWS account limits. The error message describes the limit exceeded.

HTTP Status Code: 409

MalformedPolicyDocument

The request was rejected because the policy document was malformed. The error
message describes the specific error.

HTTP Status Code: 400

NoSuchEntity

The request was rejected because it referenced a resource entity that does not
exist. The error message describes the resource.

HTTP Status Code: 404

ServiceFailure

The request processing has failed because of an unknown error, exception or
failure.

HTTP Status Code: 500

UnmodifiableEntity

The request was rejected because service-linked roles are protected AWS
resources. Only the service that depends on the service-linked role can modify
or delete the role on your behalf. The error message includes the name of the
service that depends on this service-linked role. You must request the change
through that service.

HTTP Status Code: 400
