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.
BREAKING CHANGES: 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: Tags that are passed into `var.worker_groups_launch_template` or `var.worker_groups` now override tags passed in via `var.tags` for Autoscaling Groups only. This allow ASG Tags to be overwritten, so that `propagate_at_launch` can be tweaked for a particular key.
NOTES: Keep in mind that changing the order of workers group is a destructive operation. All workers group are destroyed and recreated. If you want to do this safely, you should move then in state with `terraform state mv` until we manage workers groups as maps.
Additional support for Terraform v0.13 and aws v3!
- The update to the vpc module in examples was, strictly speaking, unnecessary but it adds the terraform block with supported versions.
- Update for iam module in the example was very necessary to support new versions
- Workaround for "Provider produced inconsistent final plan" when creating ASGs at the same time as the cluster. See https://github.com/terraform-providers/terraform-provider-aws/issues/14085 for full details.
- Blacklist 0.13.0 as it was too strict when migrating from aws v2 to v3 about dropped attributes.
In order to ensure proper ordering when running terraform destroy. This will block Terraform from removing up security group rules before the cluster has finished its clean up chores.
NOTES: New variable `worker_create_cluster_primary_security_group_rules` to allow communication between pods on workers and pods using the primary cluster security group (Managed Node Groups or Fargate). It defaults to `false` to avoid potential conflicts with existing security group rules users may have implemented.
