id

The virtual machine’s id.

its('id') { should eq(id) }

Id will be in format:

'/subscriptions/<SUBSCRIPTION_ID>/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVirtualMachine'

name

The virtual machine’s name.

its('name') { should eq('MyVmName') }

location

The virtual machine’s location.

its('location') { should eq('East US') }

type

The virtual machine’s resource type.

its('type') { should eq('Microsoft.Compute/virtualMachines') }

zones

The virtual machine’s availability zones.

its('zones') should include('zone1', 'zone2')

os_disk_name

The virtual machine’s operating system disk name.

its('os_disk_name') { should eq('OsDiskName') }

data_disk_names

The virtual machine’s data disk names.

its('data_disk_names') { should include('DataDisk1') }

installed_extensions_types

List of all installed extensions’ types for the virtual machine.

its('installed_extensions_types') { should eq(['ExtensionType']) }

installed_extensions_names

List of all installed extensions’ names for the virtual machine.

its('installed_extensions_names') { should eq(['ExtensionName']) }

Other Attributes

There are additional attributes that may be accessed that we have not documented. Please take a look at the Azure documentation. Any attribute in the response may be accessed with the key names separated by dots (.).

The API may not always return keys that do not have any associated data. There may be cases where the deeply nested property may not have the desired attribute along your call chain. If you find yourself writing tests against properties that may be nil, fork this resource pack and add an accessor to the resource. Within that accessor you’ll be able to guard against nil keys. Pull requests are always welcome.

This InSpec audit resource has the following special matchers. For a full list of available matchers, please visit our Universal Matchers page.

exists

# If a virtual machine is found it will exist
describe azurerm_virtual_machine(resource_group: 'MyResourceGroup', name: 'MyVmName') do
  it { should exist }
end

describe azurerm_virtual_machine(resource_group: 'MyResourceGroup', name: 'DoesNotExist') do
  it { should_not exist }
end

have_only_approved_extensions

# Check if a virtual machine has only approved extensions. If an extension
# is used that's not in the list then the check will fail.
describe azurerm_virtual_machine(resource_group: 'MyResourceGroup', name: 'MyVmName') do
  it { should have_only_approved_extensions(['ApprovedExtension', 'OtherApprovedExtensions']) }
end
