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 https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.5.0/components.yaml
Lets' verify the status of the metrics-server
APIService (it could take a few minutes).
kubectl get apiservice v1beta1.metrics.k8s.io -o json | jq '.status'
We are now ready to scale a deployed application
