azure_virtual_machine_disk Resource

Use the azure_virtual_machine_disk InSpec audit resource to test the properties and configuration of an Azure disk.

Azure REST API Version, Endpoint, and HTTP Client Parameters

This resource interacts with API versions supported by the resource provider. The api_version can be defined as a resource parameter. If not provided, this resource uses the latest version. For more information, refer to the azure_generic_resource document.

Unless defined, this resource uses the azure_cloud global endpoint and default values for the HTTP client. For more information, refer to the resource pack README.

Install

This resource is available in the Chef InSpec Azure resource pack.

For information on configuring your Azure environment for Chef InSpec and creating an InSpec profile that uses the InSpec Azure resource pack, see the Chef InSpec documentation for the Azure cloud platform.

Syntax

resource_group and name, or the resource_id are required parameters.

describe azure_virtual_machine_disk(resource_group: 'RESOURCE_GROUP', name: 'EXAMPLE_DISK') do
  it { should exist }
end
describe azure_virtual_machine_disk(resource_id: '/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/disks/{diskName}') do
  it { should exist }
end

Parameters

resource_group
Azure resource group where the targeted resource resides.
name
Name of the disk to test.

Either one of the parameter sets can be provided for a valid query:

  • resource_id
  • resource_group and name

Properties

encryption_enabled<superscript>*</superscript>
Indicates whether the properties.EncryptionSettingsCollection.enabled is true or false. Note that this will return nil unless the encryption status is defined on the resource explicitly.
rest_encryption_type
The type of key used to encrypt the data of the disk.
sku
The SKU (pricing tier) of the disk.
managedBy
A relative URI containing the ID of the VM that has the disk attached.
properties.diskSizeBytes
The size of the disk in bytes.

* The disk can still be encrypted at rest with a platform key, even though the encryption_enabled is nil. It is recommended to see here for more details on disk encryption.

For properties applicable to all resources, such as type, name, location, id, and properties, refer to azure_generic_resource.

Also, refer to Azure documentation for other properties available. Any attribute in the response may be accessed with the key names separated by dots (.). For example, properties.<attribute>.

Examples

Test if a disk is referenced with a valid name

describe azure_virtual_machine_disk(resource_group: 'RESOURCE_GROUP', name: 'OS_DISK') do
  it { should exist }
end

Test if a disk is referenced with an invalid name

describe azure_virtual_machine_disk(resource_group: 'RESOURCE_GROUP', name: 'i-dont-exist') do
  it { should_not exist }
end

Test the VM that the disk is attached

describe azure_virtual_machine_disk(resource_group: 'RESOURCE_GROUP', name: 'OS_DISK') do
  its('managedBy') { should cmp '/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Compute/virtualMachines/{vmName}' }
end

Test the key type used to encrypt the data at rest

describe azure_virtual_machine_disk(resource_group: 'RESOURCE_GROUP', name: 'OS_DISK') do
  its('rest_encryption_type') { should cmp 'EncryptionAtRestWithPlatformKey' }
end

Test a disk’s size in bytes

describe azure_virtual_machine_disk(resource_group: 'RESOURCE_GROUP', name: 'OS_DISK') do
  its('properties.diskSizeBytes') { should cmp 136367308800 }
end

Matchers

describe azure_virtual_machine_disk(resource_group: 'RESOURCE_GROUP', name: 'OS_DISK') do
  it { should_not exist }
end
