Getting started after deploying Kubernetes Metrics Server

After you have downloaded your kube config file, and are able to successfully connect to your DigitalOcean Kubernetes cluster (see https://cloud.digitalocean.com/kubernetes/clusters/ if you haven’t connected to your cluster) follow the instructions below to start using the metrics-server.

metrics-server The metrics-server provides cluster metrics, such as container CPU and memory usage via the Kubernetes Metrics API.

To view the metrics made available by metrics server, run the following command in a terminal shell:

kubectl top nodes

or for all Kubernetes Namespaces enter:

kubectl top pods --all-namespaces

As metrics server is running on your cluster you can also see metrics in the DigitalOcean Kubernetes Dashboard. To see your cluster metrics go to https://cloud.digitalocean.com/kubernetes/clusters → click on your cluster → click on “Insights” tab.

API Creation

In addition to creating Kubernetes Metrics Server via the control panel, you can also use the DigitalOcean API.

As an example, to create a 3 node DigitalOcean Kubernetes cluster made up of Standard Droplets in the SFO2 region, you can use the following curl command. You’ll need to either save your API access token to an environment variable or substitute it into the command below.

  curl -X POST -H "Content-Type: application/json" \
      -H "Authorization: Bearer '$TOKEN'" -d \
      '{"name": "choose-a-name","region": "sfo2","version": "1.17.5-do.0","node_pools": [{"size": "s-1vcpu-2gb","count": 3,"name": "choose-a-name"}]}' \
