 # tfmod-eks
 Create an EKS cluster given the specification of the cluster.
 
-The module creates an EKS cluster named cluster_name in the region using kuberenetes version cluster_version with eks_ng_desired_size nodes initially. The services in the cluster will be accessible using hostnames for the services ending with the cluster_name.domain fully qualified domain name. The cluster-autoscaler will resize the node group based upon capacity from a minimum of eks_ng_min_size to a maximum of eks_ng_max_size. The eks_instance_types is a prioritized list of instance types to use as the worker nodes. Note that it is best if the vCPU and Mem sizes of all of the instance types are the same.
+The module creates an EKS cluster named `cluster_name` in the region using kubernetes version `cluster_version` with `eks_ng_desired_size` nodes initially. The services in the cluster will be accessible using hostnames for the services ending with the `cluster_name.domain` fully qualified domain name. The nodegroup for karpenter will resize based upon capacity from a minimum of `eks_ng_min_size` to a maximum of `eks_ng_max_size`. After initial deployment, karpenter will create a node group for workloads that will autoscale using on-demand or spot instances with compaction based upon running workloads.
 
 The cluster is configured with an oidc provider allowing service accounts to be configured with IRSA roles as needed.
