infracost: AWS Launch Template not detected when using terraform-aws-modules/eks/aws module

Example Terraform:

provider "aws" {
  region = "us-east-1"
}

resource "aws_default_vpc" "default" {
}

data "aws_subnet_ids" "default" {
  vpc_id = aws_default_vpc.default.id
}

module "my-cluster" {
  source          = "terraform-aws-modules/eks/aws"
  cluster_name    = "my-cluster"
  cluster_version = "1.17"
  subnets         = data.aws_subnet_ids.default.ids
  vpc_id          = aws_default_vpc.default.id

  worker_groups_launch_template = [
    {
      instance_type = "m4.large"
      asg_desired_capacity  = 5
    },
  ]
}

Output is:

  NAME                                                                  MONTHLY QTY  UNIT   PRICE   HOURLY COST  MONTHLY COST

We expect that the aws_autoscaling_group.workers_launch_template[0] resource has a launch template subresource with costs.

Merged 😃 @akastav if you like, you can test it from the latest master branch. Assuming this repo is cloned and go is installed:

make deps
make -s run ARGS="breakdown --log-level info --path /path/to/code"

Thanks @akastav, I’ll dig into this a bit more and see if we can push a fix for this case.

 Terraform EKS versions

module “eks” { source = “terraform-aws-modules/eks/aws” version = “14.0.0” cluster_name = local.cluster_name cluster_version = “1.18”

worker_groups_launch_template = [ { name = “spot-group” override_instance_types = [“t3a.medium”, “t3.medium”, “t2.medium”]

It seems to work when using worker_groups instead of worker_groups_launch_template, e.g.:

module "my-cluster" {
  source          = "terraform-aws-modules/eks/aws"
  cluster_name    = "my-cluster"
  cluster_version = "1.17"
  subnets         = data.aws_subnet_ids.default.ids
  vpc_id          = aws_default_vpc.default.id

  worker_groups = [
    {
      instance_type = "m4.large"
      asg_desired_capacity  = 5
    }
  ]
}

Shows:
