# Terraform Demo

A quick demo of [Terraform](http://www.terraform.io/). It creates multiple CoreOS instances in Amazon EC2. This script is still in early development.

You will need to set the following variables either in a terraform.tfvars file or via the commandline:

```

# EC2 Variables

access_key = "YOUR_ACCESS_KEY"

secret_key = "YOUR_SECRET_KEY"

```

Also currently you need to set the count you want in the count_override.tf file. If you want ssh access set the aws_key_name variable to an aws key name or remove all references to it from this count_override.tf

```

variable "aws_key_name" {}

resource "aws_instance" "docker_host" {

  count = 3

  key_name = "${var.aws_key_name}"

}

```

To run:

 - Configure the files in the tf directory. Rename them so that they do not have the .example extension.

 - Build the container

  - ```docker build -t buildingbananas/terraform-demo .```

 - run the testing container interactively

  - ```docker run -i -t --entrypoint=/bin/bash buildingbananas/terraform-demo -s```

 - create the default 3 instance CoreOS cluster

  - ```terraform apply --var-file=terraform.tfvars -var token=$(curl https://discovery.etcd.io/new)```

##ToDo List

- [X] Work out issues with security group

- [ ] Compile terraform from source in the docker container so that it always has the latest patches

- [ ] Move the user_data to a file

- [ ] Set up count so it's an interpolated variable and remove the need for count_override.tf file

- [ ] Work out a better way method to have optional fields like key name
