You can now use the Kubernetes Metrics Server as a cluster add-on. The Kubernetes Metrics Server is a cluster-wide aggregator of resource usage data. The Kubernetes Metrics Server collects resource metrics from the kubelet running on each worker node and exposes them in the Kubernetes API server through the Kubernetes Metrics API.Using the Kubernetes Metrics Server as a cluster add-on rather than as a standalone program simplifies configuration and ongoing maintenance.

You can more simply:

• Enable or disable the Kubernetes Metrics Server.
• Opt into, and out of, automatic updates by Oracle.
• Select Kubernetes Metrics Server add-on versions.
• Manage add-on specific customizations using approved key/value pair configuration arguments.
