VirtualMachineScaleSetProperties interface

Describes the properties of a Virtual Machine Scale Set.

Properties

additionalCapabilities

Specifies additional capabilities enabled or disabled on the Virtual Machines in the Virtual Machine Scale Set. For instance: whether the Virtual Machines have the capability to support attaching managed data disks with UltraSSD_LRS storage account type.

automaticRepairsPolicy

Policy for automatic repairs.

doNotRunExtensionsOnOverprovisionedVMs

When Overprovision is enabled, extensions are launched only on the requested number of VMs which are finally kept. This property will hence ensure that the extensions do not run on the extra overprovisioned VMs.

hostGroup

Specifies information about the dedicated host group that the virtual machine scale set resides in.

Minimum api-version: 2020-06-01.

orchestrationMode

Specifies the orchestration mode for the virtual machine scale set.

overprovision

Specifies whether the Virtual Machine Scale Set should be overprovisioned.

platformFaultDomainCount

Fault Domain count for each placement group.

priorityMixPolicy

Specifies the desired targets for mixing Spot and Regular priority VMs within the same VMSS Flex instance.

proximityPlacementGroup

Specifies information about the proximity placement group that the virtual machine scale set should be assigned to.

Minimum api-version: 2018-04-01.

scaleInPolicy

Specifies the policies applied when scaling in Virtual Machines in the Virtual Machine Scale Set.

singlePlacementGroup

When true this limits the scale set to a single placement group, of max size 100 virtual machines. NOTE: If singlePlacementGroup is true, it may be modified to false. However, if singlePlacementGroup is false, it may not be modified to true.

spotRestorePolicy

Specifies the Spot Restore properties for the virtual machine scale set.

upgradePolicy

The upgrade policy.

virtualMachineProfile

The virtual machine profile.

zoneBalance

Whether to force strictly even Virtual Machine distribution cross x-zones in case there is zone outage. zoneBalance property can only be set if the zones property of the scale set contains more than one zone. If there are no zones or only one zone specified, then zoneBalance property should not be set.
