Creating the Route 53 IAM Policy
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.
The Route 53 IAM Policy allows the Cluster Manager and its nodes to access Route 53, a scalable cloud DNS web service that manages connections between users and applications running in AWS. This policy is used by the atc-route53 IAM role.
Important: If Route 53 is on a separate AWS account from your Cluster
Manager, create the Route 53 IAM policy on the account with Route 53.
