terraform azure boot_diagnostics

Using azure virtual machine boot_diagnostics (terraform)

Terraform Example of using boot_diagnostics for Azure virtual Machine
=====================================================================

- include this in the vm resource bloc:

```
.
.
.
boot_diagnostics {
    enabled = "true"
    storage_uri = "${azurerm_storage_account.diagstorage2.primary_blob_endpoint}"
}
.
.
.
```

- will need to define a boot diagnostics sa type:

```

variable "boot_diagnostics_sa_type" {
  description = "(Optional) Storage account type for boot diagnostics"
  default     = "Standard_LRS"
}

```

- create a storage account

```

/*Create a storage account to create blob storage for the boot diag output*/
resource "azurerm_storage_account" "main" {
  name                     = "bootdiag20092018001"
  resource_group_name      = "${azurerm_resource_group.main.name}"
  location                 = "${azurerm_resource_group.main.location}"
  account_tier             = "${element(split("_", var.boot_diagnostics_sa_type),0)}"
account_replication_type = "${element(split("_", var.boot_diagnostics_sa_type),1)}"
}

```
