// Creates a managed worker node group for an Amazon EKS cluster. You can only
// create a node group for your cluster that is equal to the current Kubernetes
// version for the cluster. All node groups are created with the latest AMI release
// version for the respective minor Kubernetes version of the cluster, unless you
// deploy a custom AMI using a launch template. For more information about using
// launch templates, see Launch template support
// (https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html). An
// Amazon EKS managed node group is an Amazon EC2 Auto Scaling group and associated
// Amazon EC2 instances that are managed by AWS for an Amazon EKS cluster. Each
// node group uses a version of the Amazon EKS optimized Amazon Linux 2 AMI. For
// more information, see Managed Node Groups
// (https://docs.aws.amazon.com/eks/latest/userguide/managed-node-groups.html) in
