The module lifecycle stage: General Availability

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…

You may explicitly enable or disable the module in one of the following ways:

  • Via Deckhouse web UI. In the “System” → “System Management” → “Deckhouse” → “Modules” section, open the prometheus-pushgateway module and enable (or disable) the “Module enabled” toggle. Save changes.

    Example:

    Module enable/disable interface

  • Via Deckhouse CLI (d8).

    Use the d8 system module enable command for enabling, or d8 system module disable command for disabling the module (you need Deckhouse CLI (d8), configured to work with the cluster).

    Example of enabling the module:

    d8 system module enable prometheus-pushgateway

  • Using ModuleConfig prometheus-pushgateway.

    Set spec.enabled to true or false in ModuleConfig prometheus-pushgateway (create it if necessary);

    Example of a manifest to enable module prometheus-pushgateway:

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

How to configure the module…

You can configure the module in one of the following ways:

  • Via Deckhouse web UI.

    In the “System” → “System Management” → “Deckhouse” → “Modules” section, open the prometheus-pushgateway module and enable the “Advanced Settings” switch. Fill in the required fields in the “Configuration” tab or specify the module settings in YAML format on the “YAML” tab, excluding the settings section. Save the changes.

    Example:

    Module Setup Interface

    You can also edit the ModuleConfig object prometheus-pushgateway on the “YAML” tab in the module settings window (“System” → “System Management” → “Deckhouse” → “Modules”, open the module prometheus-pushgateway) by specifying the schema version in the spec.version parameter and the necessary module parameters in the spec.settings section.

  • Via Deckhouse CLI (d8) (requires Deckhouse CLI (d8) configured to work with the cluster).

    Edit the existing ModuleConfig prometheus-pushgateway (for more details on configuring Deckhouse, see the documentation) by executing the following command:

    d8 k edit mc prometheus-pushgateway

    Make the necessary changes in the spec.settings section. If necessary, specify the schema version in the spec.version parameter. Save the changes.

    You can also create a file with manifest for ModuleConfig prometheus-pushgateway using the example below. Fill in the spec.settings section with the required module parameters. If necessary, specify the schema version in the spec.version parameter.

    Apply the manifest using the following command (indicate the manifest file name):

    d8 k apply -f <FILENAME>

    Example of a manifest for ModuleConfig prometheus-pushgateway:

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

Requirements

To the versions of other modules:

  • prometheus: any version.

Parameters

Schema version: 1

  • settings
    object
    • settings.instances
      array of strings

      Required value

      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
