cur-setup-destination

CID Terraform Module: cur-setup-destination

Terraform module to set up a Cost and Usage Report in a destination/aggregation account for use in Cost Intelligence Dashboards. The module creates an S3 bucket with the necessary permissions for replicating CUR data from one or more source accounts. If the aggregation account is part of a different payer and is not covered in the CUR from the source accounts, the module can create a new Cost and Usage Report local to the aggregation account.

Example Usage

provider "aws" {
  region = "us-west-2"
}

provider "aws" {
  region = "us-east-1"
  alias  = "useast1"
}

module "cur_destination" {
  source = "github.com/aws-samples/aws-cudos-framework-deployment//terraform-modules/cur-setup-destination"

  source_account_ids = ["1234567890"]
  create_cur         = false # Set to true to create an additional CUR in the aggregation account

  # Provider alias for us-east-1 must be passed explicitly (required for CUR setup)
  providers = {
    aws.useast1 = aws.useast1
  }
}

Version Locking

For production deployments, you should lock the version of this module to a release tag to better control when and what updates are made. To specify the release tag to use, append ?ref=VERSION to the module source. For example, the following source reference will use the Terraform module and Cloudformation template from version 0.2.13 of this module:

source = "github.com/aws-samples/aws-cudos-framework-deployment//terraform-modules/cur-setup-destination?ref=0.2.13"

For a complete list of release tags, visit https://github.com/aws-samples/aws-cudos-framework-deployment/tags.

Note: The same syntax can be used to use pre-release/beta versions by specifying a branch name instead of a tag name

Required Inputs

The following input variables are required:

Optional Inputs

The following input variables are optional (have default values):

cur_name_suffix

Description: Suffix used to name the local CUR report if create_cur is true

Type: string

Default: "cur"

kms_key_id

Description: !!!WARNING!!! EXPERIMENTAL - Do not use unless you know what you are doing. The correct key policies and IAM permissions on the S3 replication role must be configured external to this module.

• If create_cur is true, the "billingreports.amazonaws.com" service must have access to encrypt S3 objects with the key ID provided
• See https://docs.aws.amazon.com/AmazonS3/latest/userguide/replication-config-for-kms-objects.html for information on permissions required for replicating KMS-encrypted objects

Type: string

Default: null

resource_prefix

Description: Prefix used for all named resources, including S3 Bucket

Type: string

Default: "cid"

s3_access_logging

Description: S3 Access Logging configuration for the CUR bucket

Type:

object({
    enabled = bool
    bucket  = string
    prefix  = string
  })

Default:

{
  "bucket": null,
  "enabled": false,
  "prefix": null
}

enable_split_cost_allocation_data

Description: Activate split cost allocation data for ECS and EKS to aggregate cost and usage data for container-level resources

Type: bool

Default: false

Outputs

The following outputs are exported:

cur_bucket_arn

Description: ARN of the S3 Bucket where the Cost and Usage Report is delivered

cur_bucket_name

Description: Name of the S3 Bucket where the Cost and Usage Report is delivered

cur_report_arn

Description: ARN of the Cost and Usage Report
