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

How to explicitly enable the module…

Note that the configOverrides parameter of the InitConfiguration resource is used when installing Deckhouse, not ModuleConfig.

Set the nodeManagerEnabled: true or nodeManagerEnabled: false in the configOverrides parameter to explicitly enable or disable the module when installing Deckhouse.

Use the nodeManager section of the configOverrides parameter to configure the module when installing Deckhouse.

Set the spec.enabled module parameter to true or false to explicitly enable or disable the module.

Example of enabling the node-manager module:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: node-manager
spec:
  enabled: true

Example of disabling the node-manager module:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: node-manager
spec:
  enabled: false

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

Example of the ModuleConfig/node-manager resource for configuring the module:

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