AmazonIdentityManagementServiceClient.AttachRolePolicy Method (AttachRolePolicyRequest)

Attaches the specified managed policy to the specified IAM role. When you attach a managed policy to a role, the managed policy becomes part of the role's permission (access) policy.

You cannot use a managed policy as the role's trust policy. The role's trust policy is created at the same time as the role, using CreateRole. You can update a role's trust policy using UpdateAssumerolePolicy.

Use this operation to attach a managed policy to a role. To embed an inline policy in a role, use PutRolePolicy. For more information about policies, see Managed policies and inline policies in the IAM User Guide.

As a best practice, you can validate your IAM policies. To learn more, see Validating IAM policies in the IAM User Guide.

Note:

For .NET Core this operation is only available in asynchronous form. Please refer to AttachRolePolicyAsync.

Exceptions

Exception	Condition
InvalidInputException	The request was rejected because an invalid or out-of-range value was supplied for an input parameter.
LimitExceededException	The request was rejected because it attempted to create resources beyond the current Amazon Web Services account limits. The error message describes the limit exceeded.
NoSuchEntityException	The request was rejected because it referenced a resource entity that does not exist. The error message describes the resource.
PolicyNotAttachableException	The request failed because Amazon Web Services service role policies can only be attached to the service-linked role for that service.
ServiceFailureException	The request processing has failed because of an unknown error, exception or failure.
UnmodifiableEntityException	The request was rejected because service-linked roles are protected Amazon Web Services 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.
