Turning on

The module must be turned on explicitly in ModuleConfig:

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

Note for Deckhouse v1.56

After an installation of Deckhouse 1.56, one might meet a problem

Warning: module name 'deckhouse-admin' is unknown for deckhouse
moduleconfig.deckhouse.io/deckhouse-admin created

In the ModuleConfig there will be a message saying ‘unknown module name’

$ kubectl get moduleconfigs.deckhouse.io deckhouse-admin
NAME              STATE   VERSION   AGE   TYPE   STATUS
deckhouse-admin   N/A               14s   N/A    Ignored: unknown module name

To work around this, one should create a ModuleUpdatePolicy that will fix that issue for all modules in ModuleSource/deckhouse:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleUpdatePolicy
metadata:
  name: deckhouse
spec:
  moduleReleaseSelector:
    labelSelector:
      matchLabels:
        source: deckhouse
  releaseChannel: Alpha  # pick your preferable release channel here
  update:
    mode: Auto
