-# Deploy a Nomad cluster in AWS
-
-Deploys one or more servers running Nomad,  Consul and Vault as well a configurable number of clients.
-
-## Setup
-
-Clone the repo and (optionally) use the included Vagrantfile to bootstrap a local staging environment:
-
-```bash
-$ git clone git@github.com:hashicorp/nomad.git
-$ cd terraform/aws
-$ vagrant up && vagrant ssh
-```
-
-### Pre-requisites
-
-You will need the following:
-
-- AWS account
-- [API access keys](http://aws.amazon.com/developers/access-keys/)
-- [SSH key pair](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-key-pairs.html)
-
-If you are using a Vagrant environment, you will need to copy your private key to it. If not, you will need to [install Terraform](https://www.terraform.io/intro/getting-started/install.html).
-
-Set environment variables for your AWS credentials:
-
-```bash
-$ export AWS_ACCESS_KEY_ID=[ACCESS_KEY_ID]
-$ export AWS_SECRET_ACCESS_KEY=[SECRET_ACCESS_KEY]
-```
-
-## Provision
-
-`cd` to one of the environment subdirectories:
-
-```bash
-$ cd aws/env/us-east
-```
-
-Update terraform.tfvars with your SSH key name:
-
-```bash
-region                  = "us-east-1"
-ami                     = "ami-28a1dd3e"
-instance_type           = "t2.medium"
-key_name                = "KEY"
-key_file                = "/home/vagrant/.ssh/KEY.pem"
-server_count            = "3"
-client_count            = "4"
-```
-For example:
-
-```bash
-region                  = "us-east-1"
-ami                     = "ami-28a1dd3e"
-instance_type           = "t2.medium"
-key_name                = "hashi-us-east-1"
-key_file                = "/home/vagrant/.ssh/hashi-us-east-1.pem"
-server_count            = "3"
-client_count            = "4"
-```
-
-Provision:
-
-```bash
-terraform get
-terraform plan
-terraform apply
-```
-
-## Access the cluster
-
-SSH to a server using its public IP. For example:
-
-```bash
-$ ssh -i /home/vagrant/.ssh/KEY.pem ubuntu@SERVER_PUBLIC_IP
-```
-
-Please note that the AWS security group is configured by default to allow all traffic over port 22. This is not recommended for production deployments.
-
-Optionally, initialize and Unseal Vault:
-
-```bash
-$ vault init -key-shares=1 -key-threshold=1
-$ vault unseal
-$ export VAULT_TOKEN=[INITIAL_ROOT_TOKEN]
-```
-
-Test Consul, Nomad:
-
-```bash
-$ consul members
-$ nomad server-members
-$ nomad node-status
-```
-
-See the [examples](../examples/README.md).
