addRoleToInstanceProfile

Adds the specified IAM role to the specified instance profile. An instance profile can contain only one role, and this quota cannot be increased. You can remove the existing role and then add a different role to an instance profile. You must then wait for the change to appear across all of Amazon Web Services because of eventual consistency. To force the change, you must disassociate the instance profile and then associate the instance profile, or you can stop your instance and then restart it.

The caller of this operation must be granted the PassRole permission on the IAM role by a permissions policy.

When using the iam:AssociatedResourceArn condition in a policy to restrict the PassRole IAM action, special considerations apply if the policy is intended to define access for the AddRoleToInstanceProfile action. In this case, you cannot specify a Region or instance ID in the EC2 instance ARN. The ARN value must be arn:aws:ec2:*:CallerAccountId:instance/*. Using any other ARN value may lead to unexpected evaluation results.

For more information about roles, see IAM roles in the IAM User Guide. For more information about instance profiles, see Using instance profiles in the IAM User Guide.

Samples

fun main() { 
   //sampleStart 
   // The following command adds the role named S3Access to the instance profile named Webserver
iamClient.addRoleToInstanceProfile {
    roleName = "S3Access"
    instanceProfileName = "Webserver"
} 
   //sampleEnd
}
