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/sds-replicated-volume 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: sds-replicated-volume
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 sds-replicated-volume

Example of disabling the module:

  • by using the ModuleConfig resource:

    apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: sds-replicated-volume
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 sds-replicated-volume

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

Example of the ModuleConfig/sds-replicated-volume resource for configuring the module:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: sds-replicated-volume
spec:
  version: 1
  enabled: true

    object
    • settings.backup
      object

      Module backup settings.
