# azurerm\_managed\_disk

Create a managed disk.

## Example Usage with Create Empty

```
resource "azurerm_resource_group" "test" {
  name = "acctestrg"
  location = "West US 2"
}

resource "azurerm_managed_disk" "test" {
  name = "acctestmd"
  location = "West US 2"
  resource_group_name = "${azurerm_resource_group.test.name}"
  storage_account_type = "Standard_LRS"
  create_option = "Empty"
  disk_size_gb = "1"

  tags {
    environment = "staging"
  }
}
```

## Example Usage with Create Copy

```
resource "azurerm_resource_group" "test" {
  name = "acctestrg"
  location = "West US 2"
}

resource "azurerm_managed_disk" "source" {
  name = "acctestmd1"
  location = "West US 2"
  resource_group_name = "${azurerm_resource_group.test.name}"
  storage_account_type = "Standard_LRS"
  create_option = "Empty"
  disk_size_gb = "1"

  tags {
    environment = "staging"
  }
}

resource "azurerm_managed_disk" "copy" {
  name = "acctestmd2"
  location = "West US 2"
  resource_group_name = "${azurerm_resource_group.test.name}"
  storage_account_type = "Standard_LRS"
  create_option = "Copy"
  source_resource_id = "${azurerm_managed_disk.source.id}"
  disk_size_gb = "1"

  tags {
    environment = "staging"
  }
}
```

## Argument Reference

The following arguments are supported:

* `name` - (Required) Specifies the name of the managed disk. Changing this forces a
    new resource to be created.
* `resource_group_name` - (Required) The name of the resource group in which to create
    the managed disk.
* `location` - (Required) Specified the supported Azure location where the resource exists.
    Changing this forces a new resource to be created.
* `storage_account_type` - (Required) The type of storage to use for the managed disk.
    Allowable values are `Standard_LRS` or `Premium_LRS`.
* `create_option` - (Required) The method to use when creating the managed disk.
 * `Import` - Import a VHD file in to the managed disk (VHD specified with `source_uri`).
 * `Empty` - Create an empty managed disk.
 * `Copy` - Copy an existing managed disk or snapshot (specified with `source_resource_id`).
* `source_uri` - (Optional) URI to a valid VHD file to be used when `create_option` is `Import`.
* `source_resource_id` - (Optional) ID of an existing managed disk to copy when `create_option` is `Copy`.
* `os_type` - (Optional) Specify a value when the source of an `Import` or `Copy`
    operation targets a source that contains an operating system. Valid values are `Linux` or `Windows`
* `disk_size_gb` - (Required) Specifies the size of the managed disk to create in gigabytes.
    If `create_option` is `Copy`, then the value must be equal to or greater than the source's size.
* `tags` - (Optional) A mapping of tags to assign to the resource.

## Attributes Reference

The following attributes are exported:

* `id` - The managed disk ID.

## Import

Managed Disks can be imported using the `resource id`, e.g.

```
terraform import azurerm_managed_disk.test /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/mygroup1/providers/microsoft.compute/disks/manageddisk1
```
