Deploy the Metrics Server

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

These metrics will drive the scaling behavior of the deployments.

We will deploy the metrics server using Kubernetes Metrics Server.

kubectl apply -f

kubectl get apiservice -o json | jq '.status'

      "lastTransitionTime": "2020-11-10T06:39:13Z",

      "status": "True",
      "type": "Available"

We are now ready to scale a deployed application
