  1. Node-exporter service is exposed as a clusterIP with port: 9100 (controlled by nodeExporter.service.servicePort below) and targetPort: 9100 (controlled by nodeExporter.service.hostPort below) by default. Note the annotation prometheus.io/scrape: "true" is mandatory in order for node-exporter to be discovered by prometheus-server as a scrape target. See below specification for details.

    apiVersion: packages.eks.amazonaws.com/v1alpha1
kind: Package
...
spec:
  config: |
    nodeExporter:
      service:
        annotations:
          prometheus.io/scrape: "true"
        hostPort: 9100
        servicePort: 9100
        type: ClusterIP

  2. Node-exporter pods have the following toleration by default, which allows daemonSet to be scheduled on control plane node.

    apiVersion: packages.eks.amazonaws.com/v1alpha1
kind: Package
...
spec:
  config: |
    nodeExporter:
      tolerations:
        # For K8 version prior to 1.24
        - key: "node-role.kubernetes.io/master"
          operator: "Exists"
          effect: "NoSchedule"
        # For K8 version 1.24+
        - key: "node-role.kubernetes.io/control-plane"
          operator: "Exists"
          effect: "NoSchedule"
     ↩︎

  3. Prometheus-server service is exposed as a clusterIP with port: 9090 (controlled by server.service.servicePort below) and targetPort: 9090 (not overridable) by default. See below specification for details.

    apiVersion: packages.eks.amazonaws.com/v1alpha1
kind: Package
...
spec:
  config: |
    server:
      service:
        enabled: true
