Example of using Terratest and AWS module for Terrafoirm

Terratest Example

This repo contains a Terratest example where Terraform provisions a small Ubuntu 16.04 instance and checks to verify that the outputted instance id matches with the instance id asserted through Terratest. For the sake of simplicity, we are using AWS as the targeted cloud provider.

Terraform.tfvars file

The variable for creating the resource in AWS can be found in the terraform.tfvars file. The variable definitions are located in variables.tf.

Variables.tf and Terraform.tfvars files

The definition of the variables are as follows:

variable "creds" {
    type = string
}

variable "region" {
    type = string
    default = "us-east-1"
}

variable "ami" {
    type = string
}

variable "instance" {
    type = string
    default = "t2.micro"
}

These defined variable types are used in the terraform.tfvars file as follows:

# Specify path to AWS credentials
creds = "/home/hugh/.aws/credentials"

# Define the AWS region to deploy the test instance to
region = "us-west-2"


# Define the AMI and size of the instance
ami = "ami-08d70e59c07c61a3a"
instance = "t3.micro"

NOTE

It is recommended that you change creds in terraform.tfvars to the location of your AWS credentials (AWS_ACCESS_KEY and AWS_SECRET_KEY)
