Nomad AWS Module
This repo contains a set of modules for deploying a Nomad cluster on AWS using Terraform. Nomad is a distributed, highly-available data-center aware scheduler. A Nomad cluster typically includes a small number of server nodes, which are responsible for being part of the consensus protocol, and a larger number of client nodes, which are used for running jobs.
Features
- Deploy server nodes for managing jobs and client nodes running jobs
- Supports colocated clusters and separate clusters
- Least privilege security group rules for servers
- Auto scaling and Auto healing
Learn
This repo was created by Gruntwork, and follows the same patterns as the Gruntwork Infrastructure as Code Library, a collection of reusable, battle-tested, production ready infrastructure code. You can read How to use the Gruntwork Infrastructure as Code Library for an overview of how to use modules maintained by Gruntwork!
Core concepts
- Nomad Use Cases: overview of various use cases that Nomad is optimized for.
- Nomad Guides: official guide on how to configure and setup Nomad clusters as well as how to use Nomad to schedule services on to the workers.
- Nomad Security: overview of how to secure your Nomad clusters.
Repo organization
- modules: the main implementation code for this repo, broken down into multiple standalone, orthogonal submodules.
- examples: This folder contains working examples of how to use the submodules.
- test: Automated tests for the modules and examples.
- root: The root folder is an example of how to use the nomad-cluster module module to deploy a Nomad cluster in AWS. The Terraform Registry requires the root of every repo to contain Terraform code, so we've put one of the examples there. This example is great for learning and experimenting, but for production use, please use the underlying modules in the modules folder directly.
