     proximity_placement_group_id = (Optional) The ID of the Proximity Placement Group where the Virtual Machine Scale Set that powers this Node Pool will be placed. Changing this forces a new resource to be created. When setting `priority` to Spot - you must configure an `eviction_policy`, `spot_max_price` and add the applicable `node_labels` and `node_taints` [as per the Azure Documentation](https://docs.microsoft.com/azure/aks/spot-node-pool).
     spot_max_price               = (Optional) The maximum price you're willing to pay in USD per Virtual Machine. Valid values are `-1` (the current on-demand price for a Virtual Machine) or a positive value with up to five decimal places. Changing this forces a new resource to be created. This field can only be configured when `priority` is set to `Spot`.
     scale_down_mode              = (Optional) Specifies how the node pool should deal with scaled-down nodes. Allowed values are `Delete` and `Deallocate`. Defaults to `Delete`.

     ultra_ssd_enabled            = (Optional) Used to specify whether the UltraSSD is enabled in the Node Pool. Defaults to `false`. See [the documentation](https://docs.microsoft.com/azure/aks/use-ultra-disks) for more information. Changing this forces a new resource to be created.
     vnet_subnet_id               = (Optional) The ID of the Subnet where this Node Pool should exist. Changing this forces a new resource to be created. A route table must be configured on this Subnet.
