Metrics Server Configuration

Metrics Server is a scalable, efficient source of container resource metrics for Kubernetes built-in autoscaling pipelines.

Configuration options for Metrics Server

1 - Metrics Server

Install/upgrade/uninstall Metrics Server

If you have not already done so, make sure your cluster meets the package prerequisites. Be sure to refer to the troubleshooting guide in the event of a problem.

Important

Starting at eksctl anywhere version v0.12.0, packages on workload clusters are remotely managed by the management cluster.
While following this guide to install packages on a workload cluster, please make sure the kubeconfig is pointing to the management cluster that was used to create the workload cluster. The only exception is the kubectl create namespace command below, which should be run with kubeconfig pointing to the workload cluster.

Install

Generate the package configuration

eksctl anywhere generate package metrics-server --cluster <cluster-name> > metrics-server.yaml

Add the desired configuration to metrics-server.yaml

Please see complete configuration options for all configuration options and their default values.
