Infrastructure as Code Cookbook

Provisioning a complete CoreOS infrastructure on Digital Ocean with Terraform

In this recipe, we'll build from scratch a fully working CoreOS cluster on Digital Ocean in their New York region, using Terraform and cloud-init. We'll add some latency monitoring as well with StatusCake, so we have a good foundation of using Terraform on Digital Ocean.

Getting ready

To step through this recipe, you will need the following:

• A working Terraform installation
• A Digital Ocean account
• A StatusCake account
• An Internet connection

How to do it…

Let's start by creating the digitalocean provider (it only requires an API token) in a file named providers.tf:

provider "digitalocean" {
  token = "${var.do_token}"
}

Declare the do_token variable in a file named variables.tf
