About

Terrashovel is a very small CLI that scaffolds out a Terraform module.

Installation

If you have Go installed and setup:

go get -u github.com/howdoicomputer/terrashovel

Otherwise, grab the latest release and put it somewhere in your $PATH.

Usage

terrashovel create tf_test_module

cd tf_test_module
bundle install
bundle exec kitchen test

The scaffolding for the generated module deploys a single t2.micro instance into AWS and includes a single test to verify that the instance exists. The main.tf for the module looks like this:

data "aws_ami" "ubuntu" {
  most_recent = true

  filter {
    name   = "name"
    values = ["ubuntu/images/hvm-ssd/ubuntu-trusty-14.04-amd64-server-*"]
  }

  filter {
    name   = "virtualization-type"
    values = ["hvm"]
  }

  owners = ["099720109477"] # Canonical
}

resource "aws_instance" "foo" {
  instance_type = "t2.micro"
  ami           = "${data.aws_ami.ubuntu.id}"

  tags {
    Name    = "${var.name}"
    Testing = "${var.testing}"
  }
}

In a future release, I'll be moving all working code into files that are only generated under a --generate-example flag and having the default scaffolding generate non-functional, empty files.

Assumptions

The test suite used to validate created infrastructure is written in Ruby. While not a requirement for Terrashovel per se, a Ruby environment is required to install and run the suite (bundle exec kitchen test). To satisfy that requirement, I recommend RVM.
