Zero cost for an EKS cluster with terraform-aws-modules/eks/aws

[anthonydahanne]

Hello,
Using latest infracost, version 0.5.1, I tried running the following to get estimated costs for an EKS cluster created using https://github.com/terraform-aws-modules/terraform-aws-eks (it's just a couple of wrappers on top of official Terraform EKS modules, AFAIK) - but I got an empty table with a cost of 0.

TF_CLI_ARGS_plan="-var-file=variables.tfvars -var cluster_name=${CLUSTER}" infracost --tfdir .
  NAME           MONTHLY QTY  UNIT  PRICE  HOURLY COST  MONTHLY COST  

  OVERALL TOTAL                                 0.0000        0.0000  

Unfortunately, DEBUGor even TRACE logs don't help that much:

TF_CLI_ARGS_plan="-var-file=variables.tfvars -var cluster_name=${CLUSTER}" infracost --log-level=TRACE  --tfdir .
INFO Running command: /usr/bin/terraform init 
  NAME           MONTHLY QTY  UNIT  PRICE  HOURLY COST  MONTHLY COST  

  OVERALL TOTAL                                 0.0000        0.0000  

Here is the state list result on the same Terraform directory:

Interestingly enough, if I add a t2.micro, I'm gonna get some results:

resource "aws_instance" "example" {
  ami           = "ami-0e7767d1cb89be85d"
  instance_type = "t2.micro"
}

TF_CLI_ARGS_plan="-var-file=variables.tfvars -var cluster_name=${CLUSTER}" infracost --log-level=TRACE  --tfdir .

So all in all, I'm wondering if infracostcan estimate EKS costs ?

Looking at the GraphQL API (https://pricing.infracost.io/graphql) I can see EKS is there though:

query {
  products(
    filter: {
      vendorName: "aws",
      service: "AmazonEKS",
      region: "ca-central-1"
    },
  ) {
    attributes { key, value }
    prices { USD }
  }
}

will return

{
  "data": {
    "products": [
      {
        "attributes": [
          {
            "key": "servicecode",
            "value": "AmazonEKS"
          },
          {
            "key": "location",
            "value": "Canada (Central)"
          },
          {
            "key": "locationType",
            "value": "AWS Region"
          },
          {
            "key": "usagetype",
            "value": "CAN1-AmazonEKS-Hours:perCluster"
          },
          {
            "key": "operation",
            "value": "CreateOperation"
          },
          {
            "key": "servicename",
            "value": "Amazon Elastic Container Service for Kubernetes"
          },
          {
            "key": "tiertype",
            "value": "HAStandard"
          }
        ],
        "prices": [
          {
            "USD": "0.1000000000"
          }
        ]
      }
    ]
  }
}

Thanks for your help!

Thanks @anthonydahanne! Currently infracost doesn't support EKS - see https://www.infracost.io/docs/supported_resources for all currently support resources. I've added an issue for EKS here: #82.
