kube-state-metrics is a simple service that listens to the Kubernetes API server and generates metrics about the state of the objects.

Here you will find a list of yamls: link

It contains:

  1. Deployment: Where container fetches image: quay.io/coreos/kube-state-metrics:v1.6.0

  2. Service account: Service account of deployment object

  3. Role and RoleBinding: RBAC cluster role and role binding for the service account

  4. Service: k8s service that listen to the pods under deployments

So when you have all these set up. You are ready to go. Now you configure your prometheus to scrape metrics from the k8s Service you created in no. 4.

Here you will find how to generate address for the k8s service.

Configure prometheus:

global:
  scrape_interval:     15s
  evaluation_interval: 15s

scrape_configs:
  - job_name: 'kube-state-metrics'
    static_configs:
      - targets: ['address'] //address of the k8s service
