Metrics Server is a cluster-wide aggregator of resource usage data. These metrics will drive the scaling behavior of the deployments. We will deploy the metrics server using Helm configured earlier in this workshop.
kubectl create namespace metrics
helm install metrics-server \
stable/metrics-server \
--version 2.11.4 \
--namespace metrics
Return to the terminal in the Cloud9 Environment
kubectl get apiservice v1beta1.metrics.k8s.io -o yaml
It may take a minute or so for the metric service to fully initialize. If on your first attempt you don’t get the output indicated below, wait for a minute or so and try again.
If all is well, you should see a status message similar to the one below in the response
