Support additional data_disk block attribtues on spotinst_stateful_node_azure resource

[Vittitow]

Terraform Version

1.4.2

Description

Allow specifying the following attributes on the data_disk block of the spotinst_stateful_node_azure resource.

• create_option
• source_resource_id
• on_demand_bursting_enabled
• disk_iops_read_write

Use Cases

The main benefit of stateful nodes is the ability to persist the os and data disks. However, the current implementation only allows you to begin from an empty disk. It would be nice to be able to set the create option and source resource id to allow cloning from an existing snapshot/disk. Additionally, configurations like on demand bursting and iops read/write can't be specified when deploying via terraform.

I recognize you can import_vm's which would theoretically enable a lot of this but, if you deployed the vm's you're importing via terraform then it results in breaking the state of that deployment once spot kills the existing vm.

Potential Terraform Configuration

resource "spotinst_stateful_node_azure" "test_stateful_node_azure" {
  ...

  data_disk {
    size_gb                    = 2048
    lun                        = 1
    type                       = "Premium_LRS"
    create_option              = "Copy"
    source_resource_id         = "{source_resource_id}"
    on_demand_bursting_enabled = true
  }
}
