min size, max size, desired size

• https://github.com/terraform-aws-modules/terraform-aws-eks/blob/master/docs/faq.md#why-are-there-no-changes-when-a-node-groups-desired_size-is-modified

min_size
max_size
desired_size Changing the desired count must be handled outside of Terraform once the node group is created. Changin in terraform is not supported

Stop all nodes in your EKS cluster:

• eksctl scale nodegroup --cluster <CLUSTERNAME> --name <NODEGROUPNAME> --nodes 0 --nodes-max 1 --nodes-min 0

Check:

• kubectl get nodes

• aws autoscaling update-auto-scaling-group

Errors

• Error: expected scaling_config.0.max_size to be at least (1), got 0
• InvalidParameterException: desiredSize is not valid
• Error: updating EKS Node Group
