 ## Notes
 
 - By default, this module manages the `aws-auth` configmap for you (`manage_aws_auth=true`). To avoid the following [issue](https://github.com/aws/containers-roadmap/issues/654) where the EKS creation is `ACTIVE` but not ready. We implemented a "retry" logic with a [fork of the http provider](https://github.com/terraform-aws-modules/terraform-provider-http). This fork adds the support of a self-signed CA certificate. The original PR can be found [here](https://github.com/hashicorp/terraform-provider-http/pull/29).
 
 - Setting `instance_refresh_enabled = true` will recreate your worker nodes without draining them first. It is recommended to install [aws-node-termination-handler](https://github.com/aws/aws-node-termination-handler) for proper node draining. Find the complete example here [instance_refresh](https://github.com/terraform-aws-modules/terraform-aws-eks/tree/master/examples/instance_refresh).
