Description

DescribeAutoScalingGroups can return a LaunchTemplateSpecification, which is currently not exposed in the aws_autoscaling_group data source. I would like to use this values to identify the aws_launch_template which is auto-generated when a aws_eks_node_group is created.

New or Affected Resource(s)

• data source aws_autoscaling_group

Potential Terraform Configuration

resource "aws_eks_node_group" "ng" {
  count = var.availability_zone_count
  // ...
}

data "aws_autoscaling_group" "asg" {
  count = var.availability_zone_count
  name = aws_eks_node_group.ng[count.index].resources.0.autoscaling_groups.0.name
}

data "aws_launch_template" "lt" {
  count = var.availability_zone_count
  name = data.aws_autoscaling_group.asg[count.index].launch_template.name
}
