BREAKING CHANGES:

• This module used random_pet resources to create a random name for the autoscaling group to force the autoscaling group to be re-created when the launch configuration or launch template was changed (if recreate_asg_when_lc_changes = true was set), causing the instances to be removed and re-provisioned each time there was an update. Those random_pet resources has been removed and in its place there is now a set of functionality provided by AWS and the Terraform AWS provider - Instance Refresh. We encourage those users to move on Instance Refresh for EC2 Auto Scaling.
• We remove the dependency on the deprecated hashicorp/template provider and use the Terraform built in templatefile function. This will broke some workflows due to previously being able to pass in the raw contents of a template file for processing. The templatefile function requires a template file that exists before running a plan.

NOTES:

• Using the terraform-aws-modules/http provider is a more platform agnostic way to wait for the cluster availability than using a local-exec. With this change we're able to provision EKS clusters and manage the aws_auth configmap while still using the hashicorp/tfc-agent docker image.
