Terraform Module for Provisioning Nomad on AWS

Nomad AWS Module

This is a Terraform module for provisioning a Nomad Cluster on AWS. This cluster utilizes Consul as recommended by the Nomad Reference Architecture. The default is set to 5 servers and 3 clients.

About This Module

This module implements the Nomad Reference Architecture. It is created and maintained by HashiCorp to exist as a canonical implementation of a Nomad cluster in the Amazon Web Services cloud, and enforces this prescriptive methodology through the use of default values corresponding to the recommendations of our Enterprise Architects.

For more advanced practitioners requiring a wider variety of configurable options, please see Terraform AWS Nomad Module.

How to Use This Module

• Create a Terraform configuration (main.tf) that pulls in the module and specifies values of the required variables:

provider "aws" {
  region = "<your AWS region>"
}

module "nomad-oss" {
  source                = "hashicorp/nomad-oss/aws"
  version               = "<module version>"
  allowed_inbound_cidrs = ["<list of inbound CIDRs>"]
  vpc_id                = "<your VPC id>"
  consul_version        = "<consul version (ex: 1.8.3)>"
  nomad_version         = "<nomad version (ex: 0.12.3)>"
  owner                 = "<owner name/tag>"
  name_prefix           = "<name prefix you would like attached to your environment>"
  key_name              = "<your SSH key name>"
  nomad_servers         = 5
  nomad_clients         = 3
}

• version: The Nomad AWS module version to pull (e.g. 0.2.1) during the initialization
• allowed_inbound_cidrs: Allowed CIDR blocks for SSH and API/UI access
• vpc_id: ID of the VPC where cloud resources to be provisioned
• consul_version: Desired Consul version to install
• nomad_version: Desired Nomad version to install
• key_name: The name of the SSH key pairs to use. This must exist in the specified AWS region

Run terraform init and terraform apply to provision a Nomad cluster.
