The deckhouse module: configuration

Schema version: 1

• settings

  object
  • settings.bundle

    string

    The Deckhouse bundle defines a set of modules enabled by default.

    • 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 modules Minimal (for example, the CNI module). Deckhouse with the set of modules Minimal 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
    

  • settings.highAvailability

    boolean

    Manually enable the high availability mode.

    By default, Deckhouse automatically decides whether to enable the HA mode. Click here to learn more about the HA mode for modules.

    Example:

    highAvailability: true
    

  • settings.logLevel

    string

    Deckhouse logging level.

    Default: "Info"

    Allowed values: Debug, Info, Error

    Example:

    logLevel: Info
    

  • settings.nodeSelector

    object

    The same as in the Pods’ spec.nodeSelector parameter in Kubernetes.

    If the parameter is omitted or false, nodeSelector will be determined automatically.

    Cation! Deckhouse will stop working if there is a nonexistent label in nodeSelector. You need to change the values to the correct ones in ModuleConfig/deckhouse and deployment/deckhouse to get Deckhouse back on track.

  • settings.releaseChannel

    string

    Desirable Deckhouse release channel (Deckhouse will switch to it when such an opportunity appears).

    The order in which the stability of the release channel increases (from less stable to more stable): Alpha, Beta, EarlyAccess, Stable, RockSolid.

    Allowed values: Alpha, Beta, EarlyAccess, Stable, RockSolid

    Example:

    releaseChannel: Stable
    

  • settings.tolerations

    array of objects

    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 in ModuleConfig/deckhouse and deployment/deckhouse to get Deckhouse back on track.

    • settings.tolerations.effect

      string
    • settings.tolerations.key

      string
    • settings.tolerations.operator

      string
    • settings.tolerations.tolerationSeconds

      integer
    • settings.tolerations.value

      string
  • settings.update

    object

    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
    

    • settings.update.disruptionApprovalMode

      string

      Deckhouse release update disruption mode:

      • Auto — approves release with disruptions (potentially dangerous changes) automatically.
      • Manual — requires manual release confirmation (set the release.deckhouse.io/disruption-approved=true annotation on the appropriate DeckhouseRelease resource to apply the update).

      Default: "Auto"

      Allowed values: Auto, Manual

    • settings.update.mode

      string

      Update mode of Deckhouse on the selected release channel.

      • AutoPatch — automatic update mode for patch releases.

        To change a minor version (for example, from v1.65.* to v1.66.*), confirmation is required.

        A patch version update (for example, from v1.65.1 to v1.65.4) is applied according to the update windows, if they are set.

      • Auto — automatic update mode for all versions.

        A minor version update (for example, from v1.65.* to v1.66.*) is applied according to the update windows, if they are set.

        A patch version update (for example, from v1.65.1 to v1.65.4) is applied regardless of the update windows (immediately).

      • Manual — manual update mode for all versions.

        Confirmation is required for updating both minor and patch versions.

      To confirm the version update, it is necessary to set the approved field to true in the corresponding resource DeckhouseRelease.

      Default: "AutoPatch"

      Allowed values: AutoPatch, Auto, Manual

    • settings.update.notification

      object

      Settings for notifications of scheduled Deckhouse updates.

      Has the effect only when the automatic update mode is set.

      Example:

      notification:
        webhook: https://release-webhook.mydomain.com
        minimalNotificationTime: 8h
      

      • settings.update.notification.auth

        object

        Authentication settings for the webhook.

        If the parameter is omitted, the webhook will be called without authentication.

        • settings.update.notification.auth.basic

          object

          Basic authentication settings for the webhook.

          If the parameter is omitted, the webhook will be called without authentication.

          • settings.update.notification.auth.basic.password

            string

            Required value

            The password for the webhook.

            The username and password will be sent in the Authorization header in the format Basic <base64(username:password)>.

          • settings.update.notification.auth.basic.username

            string

            Required value

            The username for the webhook.

            The username and password will be sent in the Authorization header in the format Basic <base64(username:password)>.

        • settings.update.notification.auth.bearerToken

          string

          The token for the webhook.

          The token will be sent in the Authorization header in the format Bearer <token>.

      • settings.update.notification.minimalNotificationTime

        string

        The minimum time that must pass before updating from the moment a new minor version appears on the release channel used.

        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
        

      • settings.update.notification.releaseType

        string

        Defines the type of version for which the notification will be sent:

        • Minor — only for updating the minor version.
        • All — for any updates, including updating a patch version.

        Default: "Minor"

        Allowed values: All, Minor

        Example:

        releaseType: All
        

      • settings.update.notification.tlsSkipVerify

        boolean

        Skip TLS certificate verification while webhook request.

        Default: false

      • settings.update.notification.webhook

        string

        URL for an external webhook handler.

        The POST request will be sent to the webhook URL after a new minor version of Deckhouse appears on the update channel before it is applied to the cluster.

        Caution! If you specify an invalid webhook address, Deckhouse update will be blocked.

        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):

        {
          "subject":"Deckhouse",
          "version": "1.36.0",
          "requirements":  {"k8s": "1.20.0"},
