The module is enabled by default in the following bundles: Default
, Managed
, Minimal
.
The module is configured using the ModuleConfig custom resource named deckhouse
(learn more about setting up Deckhouse…).
Example of the ModuleConfig/deckhouse
resource for configuring the module:
apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
name: deckhouse
spec:
version: 1
enabled: true
settings: # <-- Module parameters from the "Parameters" section below.

Default
— the recommended set of modules for cluster operation: monitoring, authorization control, networking and other needs.Managed
— the bundle aimed at clusters managed by cloud providers (e.g., Google Kubernetes Engine).Minimal
— the minimum possible bundle option (includes a single module — this one). Note that several basic modules are not included in the set of modulesMinimal
(for example, the CNI module). Deckhouse with the set of modulesMinimal
without the basic modules will be able to work only in an already deployed cluster.
Default:
"Default"
Allowed values:
Default
,Minimal
,Managed
Example:
bundle: Default

parameter in Kubernetes.If the parameter is omitted or
false
,nodeSelector

nodeSelector
. You need to change the values to the correct ones inModuleConfig/deckhouse

,RockSolid
Example:
releaseChannel: Stable
- tolerations
The same as in the Pods’
spec.tolerations
parameter in Kubernetes;If the parameter is omitted or
false
,tolerations
will be determined automatically.Cation! Deckhouse will stop working if
tolerations
specified are incorrect. You need to change the values to the correct ones inModuleConfig/deckhouse
anddeployment/deckhouse
to get Deckhouse back on track.- tolerations.effect
- tolerations.key
- tolerations.operator
- tolerations.tolerationSeconds
- tolerations.value
- update
Settings of the Deckhouse update mode and windows.
Example:
update: windows: - from: '8:00' to: '15:00' days: - Tue - Sat disruptionApprovalMode: Manual notification: webhook: https://release-webhook.mydomain.com minimalNotificationTime: 6h auth: basic: username: user password: password
- update.disruptionApprovalMode
Deckhouse release update disruption mode:
Auto

Default:
"Auto"
Allowed values:
Auto
,Manual

tov1.27.*
), are applied according to the update windows or (if no update windows are set) as they appear on the corresponding release channel; -
Manual
— to change a minor version of Deckhouse (for example, fromv1.26.*
tov1.27.*
), manual confirmation is required.To confirm the update, edit custom resource ‘DeckhouseRelease’, which corresponds to the version by setting the `approved’ field to ‘true’.
Default:
"Auto"
Allowed values:
Auto
,Manual

Basic authentication settings for the webhook.
If the parameter is omitted, the webhook will be called without authentication.
- update.notification.auth.basic.password

It is specified as a string containing the time unit in hours and minutes: 30m, 1h, 2h30m, 24h.
The update mechanism ensures that Deckhouse will not be updated until a specified period of time has passed.
When using update windows, the Deckhouse update will happen at the nearest possible update window but not before the time specified in
minimalNotificationTime
expires.Pattern:
^([0-9]+h([0-9]+m)?|[0-9]+m)$
Example:
minimalNotificationTime: 6h

The POST request will be sent on the webhook URL after a new minor version of Deckhouse appears on the update channel before it is applied to the cluster.
Use the minimalNotificationTime parameter if necessary to set the minimum time that must pass before updating from the moment a new minor version appears on the release channel used.
Example of the POST request payload (
Content-Type: application/json
