Metrics Server

Metrics Server is a scalable, efficient source of container resource metrics for Kubernetes built-in autoscaling pipelines. It is not deployed by default in Amazon EKS clusters. The Metrics Server is commonly used by other Kubernetes add-ons, such as the Horizontal Pod Autoscaler, Vertical Autoscaling or the Kubernetes Dashboard.

Important: Don't use Metrics Server when you need an accurate source of resource usage metrics or as a monitoring solution.

Usage

Metrics Server can be deployed by enabling the add-on via the following.

enable_metrics_server = true

Once deployed, you can see metrics-server pod in the kube-system namespace.

$ kubectl get deployments -n kube-system

NAME                                                          READY   UP-TO-DATE   AVAILABLE   AGE
metrics-server                                                1/1     1            1           20m

GitOps Configuration

The following properties are made available for use when managing the add-on via GitOps

metricsServer = {
  enable = true
}
