> Terraform module that uses the [AWS Pricing API](https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/price-changes.html) to query EC2 instance type attributes

## Usage

```tf

module "instance" {

  source        = "bendrucker/ec2-pricing/aws"

  instance_type = "m5.large"

}

```

The module exposes outputs that describe key attributes of the specified instance type. These values are helpful for creating monitoring or resource quotas that are defined relative to the instance's capacity.

For example, you might pass these along to a [`kubernetes_resource_quota`](https://www.terraform.io/docs/providers/kubernetes/r/resource_quota.html) in order to assign a percentage of cluster capacity to a namespace:

```tf

locals {

  # allow developers to use 80% of worker resources

  # reserve the remaining 20% for system components

  developer_quota = 0.8

}

resource "kubernetes_resource_quota" "developers" {

  metadata {

    name      = "developers-quota"

    namespace = "developers"

  }

  spec {

    hard = {

      cpu    = var.worker_count * module.instance.cpus * local.developer_quota

      memory = "${var.worker_count * module.instance.memory * local.developer_quota} GiB"

    }

  }

}

```
