# AWS Quickstart Terraform configs

The AWS Quickstart Terraform configs can be used to create the needed
infrastructure for a Kubernetes HA cluster. Check out the
[Creating Infrastructure guide][docs-infrastructure] to learn more about how to
use the configs and how to provision a Kubernetes cluster using KubeOne.
