Deploy the Metric server

Deploy the Metrics Server

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

Confirm the Metrics API is available.

Return to the terminal in the Cloud9 Environment

kubectl get apiservice -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
