This module installs Prometheus Pushgateway into the cluster. It receives metrics from the app and pushes them to Prometheus.

The module is not enabled by default in any bundles.

How to explicitly enable the module…

Set the spec.enabled module parameter to true or false in the ModuleConfig/prometheus-pushgateway 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: prometheus-pushgateway
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 svc/deckhouse-leader -c deckhouse -- deckhouse-controller module enable prometheus-pushgateway

Example of disabling the module:

  • by using the ModuleConfig resource:

    apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: prometheus-pushgateway
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 svc/deckhouse-leader -c deckhouse -- deckhouse-controller module disable prometheus-pushgateway

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

Example of the ModuleConfig/prometheus-pushgateway resource for configuring the module:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: prometheus-pushgateway
spec:
  version: 1
  enabled: true

Parameters

Schema version: 1

  • settings
    object
    • settings.instances
      array of strings

      This parameter contains a list of instances; a separate PushGateway will be created for each instance.

      Example:

      instances:
- first
- second
    • settings.nodeSelector
      object

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

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

    • settings.tolerations
      array 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.

      • settings.tolerations.effect
        string
      • settings.tolerations.key
        string
      • settings.tolerations.operator
        string
      • settings.tolerations.tolerationSeconds
        integer
      • settings.tolerations.value
        string
