Terraform example

This folder contains an example of how define infrastructure-as-code using Terraform. The Terraform templates in this folder show how to use the Terraform module defined in the rails-module folder to take the AMI created in the packer-example folder, deploy it on an EC2 instance, and run the Ruby on Rails app within the AMI.

Quick start

Note: these Terraform templates create real resources in your AWS account. The resources are part of the AWS Free Tier, but if you've used up all your credits, they may cost you money.

1. Install Terraform.
2. Open vars.tf, set the environment variables specified at the top of the file, and fill in any other variables that don't have a default.
3. Run terraform get.
4. Run terraform plan.
5. If the plan looks good, run terraform apply.
6. After the templates have been applied, Terraform will output a URL. Once the server is up and running (which can take 1-2 minutes), visit this URL to test the Rails app. You should see the text "Hello, World".

Cleaning up

To clean up the resources created by these templates, just run terraform destroy.
