terraform-aws-eks

Overview

This is just a simple EKS module for terraform which I am using for learning and testing purposes.

An optionable bastian host can be created if you intend to protect your cluster in a private network, thus not accessible from internet. If that's the case, then set the variable create_bastion_host to true.

The work here is currently in progress.
