The Deckhouse Kubernetes Platform installs CRDs but does not remove them when a module is disabled. If you no longer need the created CRDs, delete them.

      • spec.rootDisk.storageClass
        string

        The name of the existing StorageClass will be used to create the virtual machine’s root disk.

        If the value is not specified, the StorageClass will be used according to the global storageClass parameter setting.

    • spec.virtualMachine
      object

      Required value

      Virtual machine settings for the created node.

      The runPolicy: AlwaysOnUnlessStoppedManually policy is used for virtual machines of nodes. This allows the virtual machine to be stopped manually (for example, for maintenance) without triggering an automatic restart.

      • spec.virtualMachine.bootloader
        string

        Defines a bootloader for the virtual machine.

        • BIOS: Use BIOS.
        • EFI: Use Unified Extensible Firmware (EFI/UEFI).
        • EFIWithSecureBoot: Use UEFI/EFI with the Secure Boot support.

        Default: EFI

        Allowed values: BIOS, EFI, EFIWithSecureBoot

      • spec.virtualMachine.cpu
        object

        Required value

        CPU settings for the virtual machine.

        • spec.virtualMachine.cpu.coreFraction
          string

          Guaranteed share of CPU fraction that will be allocated to the virtual machine.

          Default: 100%

          Pattern: ^100%$|^[1-9][0-9]?%$

          Example:

          coreFraction: 100%
        • spec.virtualMachine.cpu.cores
          integer

          Required value

          Number of CPU cores for the virtual machine.

          Allowed values: 1 <= X

          Example:

          cores: 4
      • spec.virtualMachine.liveMigrationPolicy
        string

        Live migration policy for the virtual machine.

        • Manual: Migration is controlled manually.
        • Never: Migration is disabled.
        • AlwaysSafe: Always use safe migration (may fail if VM has a high rate of memory changes).
        • PreferSafe: Prefer safe migration, fallback to forced if needed.
        • AlwaysForced: Always use forced migration with VM slowdown.
        • PreferForced: Prefer forced migration (recommended for master nodes due to high memory activity).

        Default: PreferForced

        Allowed values: Manual, Never, AlwaysSafe, PreferSafe, AlwaysForced, PreferForced

        Example:

        liveMigrationPolicy: PreferForced
      • spec.virtualMachine.memory
        object

        Required value

        Specifies the memory settings for the virtual machine.

        • spec.virtualMachine.memory.size
          string

          Required value

          Amount of memory resources allowed for the virtual machine.

          Pattern: ^(\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))(([KMGTPE]i)|[numkMGTPE]|([eE](\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))))?$

          Example:

          size: 4Gi
      • spec.virtualMachine.runPolicy
        string

        Virtual machine run policy.

        • AlwaysOn: The virtual machine should always be running.
        • AlwaysOff: The virtual machine should always be stopped.
        • Manual: The virtual machine state is controlled manually.
        • AlwaysOnUnlessStoppedManually: The virtual machine can be stopped manually (for example, for maintenance), but it will automatically start after a host reboot.

        Default: AlwaysOnUnlessStoppedManually

        Allowed values: AlwaysOn, AlwaysOff, Manual, AlwaysOnUnlessStoppedManually

        Example:

        runPolicy: AlwaysOnUnlessStoppedManually
      • spec.virtualMachine.virtualMachineClassName
        string

        Required value

        The name of the VirtualMachineClass.

        Intended for centralized configuration of preferred virtual machine parameters. It allows you to specify CPU instruction sets, resource configuration policies for CPU and memory, and define the ratio between these resources.
