About the azurerm_virtual_network Resource
azure

WARNING This resource will be deprecated in InSpec Azure Resource Pack version 2. Please start using fully backward compatible azure_virtual_network InSpec audit resource.

azurerm_virtual_network

Use the azurerm_virtual_network InSpec audit resource to test properties related to a virtual network.


Azure REST API version

This resource interacts with version 2018-02-01 of the Azure Management API. For more information see the official Azure documentation.

At the moment, there doesn't appear to be a way to select the version of the Azure API docs. If you notice a newer version being referenced in the official documentation please open an issue or submit a pull request using the updated version.

You'll also need to setup your Azure credentials; see the resource pack README.

Version

This resource first became available in 1.1.0 of the inspec-azure resource pack.

Syntax

The resource_group and virtual network name must be given as parameters.

describe azurerm_virtual_network(resource_group: 'MyResourceGroup', name: 'MyVnetName') do
  ...
end

Examples

Ensure that the virtual network exists in the East US region

describe azurerm_virtual_network(resource_group: resource_group, name: 'MyVnetName') do
  it               { should exist }
  its('location')  { should eq 'East US' }
end

Ensure that the virtual network's dns servers are configured as expected.

describe azurerm_virtual_network(resource_group: resource_group, name: 'MyVnetName') do
    its('dns_servers') { should eq ["192.168.0.6"] }
end

Ensure that the virtual network's address space is configured as expected.

describe azurerm_virtual_network(resource_group: resource_group, name: 'MyVnetName') do
    its('address_space') { should eq ["192.168.0.0/24"] }
end

Parameters

  • resource_group, name

Boolean value showing if Azure DDoS standard protection is enabled on the virtual network.

its('enable_ddos_protection') { should eq true }

enable_vm_protection

Boolean value showing if the virtual network has VM protection enabled.

its('enable_vm_protection') { should eq false }

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.

Matchers

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 network is found it will exist
describe azurerm_virtual_network(resource_group: 'MyResourceGroup', name: 'MyVnetName') do
  it { should exist }
end

# virtual networks that aren't found will not exist
describe azurerm_virtual_network(resource_group: 'MyResourceGroup', name: 'DoesNotExist') do
  it { should_not exist }
end
