The module is enabled by default in the following bundles: Default, Managed. The module is disabled by default in the Minimal bundle.

How to explicitly enable the module…

Set the spec.enabled module parameter to true or false in the ModuleConfig/monitoring-kubernetes resource (create it, if necessary) to explicitly enable or disable the module, or use the deckhouse-controller module command in the d8-system/deckhouse pod.

Example of enabling the module:

  • by using the ModuleConfig resource:

    apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: monitoring-kubernetes
spec:
  enabled: true

  • by using the deckhouse-controller command (you need a kubectl, configured to work with the cluster):

    kubectl -ti -n d8-system exec deploy/deckhouse -c deckhouse -- deckhouse-controller module enable monitoring-kubernetes

Example of disabling the module:

  • by using the ModuleConfig resource:

    apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: monitoring-kubernetes
spec:
  enabled: false

  • by using the deckhouse-controller command (you need a kubectl, configured to work with the cluster):

    kubectl -ti -n d8-system exec deploy/deckhouse -c deckhouse -- deckhouse-controller module disable monitoring-kubernetes

The module is configured using the ModuleConfig custom resource named monitoring-kubernetes (learn more about setting up Deckhouse…).

Example of the ModuleConfig/monitoring-kubernetes resource for configuring the module:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: monitoring-kubernetes
spec:
  version: 1
  enabled: true
  settings: # <-- Module parameters from the "Parameters" section below.

Parameters

Schema version: 1

  • highAvailabilityboolean

    Manually enable the high availability mode.

    By default, Deckhouse automatically decides whether to enable the HA mode. Click here to learn more about the HA mode for modules.

    Examples:

    highAvailability: true

    highAvailability: false
  • nodeSelectorobject

    The same as in the pods’ spec.nodeSelector parameter in Kubernetes.

    If the parameter is omitted or false, it will be determined automatically.

    Example:

    nodeSelector:
  disktype: ssd
  • tolerationsarray of objects

    The same as in the pods’ spec.tolerations parameter in Kubernetes;

    If the parameter is omitted or false, it will be determined automatically.

    Example:

    tolerations:
- key: key1
  operator: Equal
  value: value1
  effect: NoSchedule
    • tolerations.effectstring
    • tolerations.keystring
    • tolerations.operatorstring
    • tolerations.tolerationSecondsinteger
    • tolerations.valuestring
  • vpaobject

    VPA settings for kube-state-metrics pods.

    Example:

    vpa:
  kubeStateMetricsMaxCPU: 130m
  kubeStateMetricsMaxMemory: 115Mi
    • vpa.kubeStateMetricsMaxCPU

      The maximum value that the VPA can set for the CPU requests.

      Examples:

      kubeStateMetricsMaxCPU: 3

      kubeStateMetricsMaxCPU: 1000m
    • vpa.kubeStateMetricsMaxMemory

      The maximum memory requests the VPA can set.

      Example:

      kubeStateMetricsMaxMemory: 3Mi
