azure_generic_resource resource

[edit on GitHub]

Warning

This resource is deprecated and should not be used. It will be removed in Chef InSpec 5.0. Instead of using any of the demonstration Azure resources included with Chef InSpec, use the inspec-azure resource pack, which offers rich functionality and specific resources to fit many common use cases.

Use the azure_generic_resource Chef InSpec audit resource to test any valid Azure Resource. This is very useful if you need to test something that we do not yet have a specific Chef InSpec resource for.

Availability

Installation

This resource is distributed along with Chef InSpec itself. You can use it automatically.

Version

This resource first became available in v2.0.16 of InSpec.

Syntax

describe azure_generic_resource(group_name: 'MyResourceGroup', name: 'MyResource') do
  its('property') { should eq 'value' }
end

where:

  • MyResourceGroup is the name of the resource group that contains the Azure Resource to be validated
  • MyResource is the name of the resource that needs to be checked
  • property This generic resource dynamically creates the properties on the fly based on the type of resource that has been targeted.
  • value is the expected output from the chosen property

Parameters

  • group_name
  • name
  • apiversion
  • type

The options that can be passed to the resource are as follows.

group_name (required)

Use this parameter to define the Azure Resource Group to be tested.

describe azure_virtual_machine_data_disk(group_name: 'InSpec-Azure') do
    ...
end

name

Use this parameter to define the name of the Azure resource to test.

describe azure_virtual_machine_data_disk(group_name: 'InSpec-Azure', name: 'Windows-Internal-VM') do
    ...
end

apiversion

The API Version to use when querying the resource. Defaults to the latest version for the resource.

describe azure_virtual_machine_data_disk(group_name: 'InSpec-Azure', name: 'Windows-Internal-VM', apiversion: '2.0') do
    ...
end

type

Use this parameter to define the type of resources to test.

describe azure_virtual_machine_data_disk(group_name: 'InSpec-Azure', name: 'Windows-Internal-VM', apiversion: '2.0', type: 'Microsoft.Compute/virtualMachines') do
    ...
end

These options can also be set using the environment variables:

  • AZURE_RESOURCE_GROUP_NAME
  • AZURE_RESOURCE_NAME
  • AZURE_RESOURCE_TYPE
  • AZURE_RESOURCE_API_VERSION

When the options have been set as well as the environment variables, the environment variables take priority.

Parameter Example

describe azure_generic_resource(group_name: 'Inspec-Azure', name: 'Linux-Internal-VM', apiversion: '2.0') do
  its('location') { should eq 'westeurope' }
end

Properties

The properties that can be tested are entirely dependent on the Azure Resource that is under scrutiny. That means the properties vary. The best way to see what is available please use the Azure Resources Portal to select the resource you are interested in and see what can be tested.

This resource allows you to test any valid Azure Resource. The trade off for this is that the language to check each item is not as natural as it would be for a native Chef InSpec resource.

Property Examples

The following examples show how to use some of the Chef InSpec audit properties:

Tests the virtual machine’s location

its('location') { should cmp 'westeurope' }

Tests for the presence of a specified address prefix

its('properties.addressSpace.addressPrefixes') { should include '10.1.1.0/24' }

Tests that virtual machine was created from the correct disk

its('properties.creationData.createOption') { should eq 'FromImage' }

Tests that the image is Ubuntu

its('properties.creationData.imageReference.id') { should match 'Canonical' }
its('properties.creationData.imageReference.id') { should match 'UbuntuServer' }
its('properties.creationData.imageReference.id') { should match '16.04.0-LTS' }

Tests the disk size

its('properties.diskSizeGB') { should be > 25 }

Tests the disk state

its('properties.diskState') { should cmp 'Attached' }

Tests that there are no custom DNS settings

its('properties.dnsSettings.dnsServers.count') { should eq 0 }
its('properties.dnsSettings.appliedDnsServers.count') { should eq 0 }

Tests that the NIC is connected to the correct machine

its('properties.virtualMachine.id') { should match 'Linux-External-VM' }

Tests that the blob and file services are enabled

its('properties.encryption.services.blob.enabled') { should be true }
its('properties.encryption.services.file.enabled') { should be true }
its('properties.encryption.keySource') { should cmp 'Microsoft.Storage' }

Test the hardware profile

its('properties.hardwareProfile.vmSize') { should cmp 'Standard_DS2_v2' }

Test the network interfaces

its('properties.networkProfile.networkInterfaces.count') { should eq 1 }

Test the authentication and OS type

its('properties.osProfile.computerName') { should eq 'linux-external-1' }
its('properties.osProfile.adminUsername') { should eq 'azure' }
its('properties.osProfile.linuxConfiguration.disablePasswordAuthentication') { should be true }

Test that the tags are properly set

it { should have_tags }
its('tag_count') { should be 1 }
