AWS HashiStack Terraform Module

Provisions resources for a HashiStack auto-scaling group in AWS.

  • A HashiStack cluster with one node in each private subnet

Requirements

This module requires a pre-existing AWS key pair, VPC and subnet be available to deploy the auto-scaling group within. It's recommended you combine this module with network-aws which provisions a VPC and a private and public subnet per AZ. See the usage section for further guidance.
