User Story:

As a (user persona), I'd like to see cluster nodes (EC2 instances) being created with a network interface associated with a primary IPv6 from my dual-stack VPC. This allows the nodes to be part of an IPv6-enabled Target Group registered to the API LB.

Acceptance Criteria:

Description of criteria:

• Cluster nodes (EC2 instances) are created with a network interface associated with a primary IPv6.

(optional) Out of Scope:
