Creating the Route 53 IAM Role
AWS Identity & Access Management (IAM) manages credentials for the ATC Manager and its nodes by assigning IAM roles to them when they are launched. Attaching policies to these roles grant the associated instances permissions such as starting, stopping, and terminating instances in EC2, updating records in the Route 53 service,or associating IAM roles with a new instance.
This IAM role requires that the following policy has already been configured: atc-route53-policy. For more information about the atc-route53-policy, see Creating the Route 53 IAM Policy.
Authorize the atc-manager and atc-node Roles
Authorize the atc-manager and atc-node roles to use the permissions in the atc-route53 role by editing the atc-route53 role's trust relationship.
