azure_generic_resource Resource

Use the azure_generic_resource Inspec audit resource to test any valid Azure resource available through Azure Resource Manager.

Installation

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

See the Chef InSpec documentation on cloud platforms for information on configuring your Azure environment for InSpec and creating an InSpec profile that uses the InSpec Azure resource pack.

Syntax

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

where

Resource parameters are used to query Azure Resource Manager endpoint for the resource to be tested.
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

The following parameters can be passed for targeting a specific Azure resource.

resource_group: Azure resource group that the targeted resource has been created in. MyResourceGroup.
name: Name of the Azure resource to test. MyResourceName.
resource_provider: Azure resource provider of the resource to be tested. Microsoft.Compute/virtualMachines.
resource_path: Relative path to the resource if it is defined on another resource. Resource path of a subnet in a virtual network would be: {virtualNetworkName}/subnets.
resource_id: Unique id of Azure resource to be tested. /subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Compute/virtualMachines/{vmName}.
resource_uri: Azure REST API URI of the resource to be tested. This parameter should be used when a resource does not reside in a resource group. It requires add_subscription_id and name parameters to be provided together. /providers/Microsoft.Authorization/policyDefinitions/.
add_subscription_id: Indicates whether the resource_uri contains the subscription id. true or false.
tag_name<superscript>*</superscript>: Tag name defined on the Azure resource. name.
tag_value: Tag value of the tag defined with the tag_name. external_linux.
api_version: API version to use when interrogating the resource. If not set or the provided api version is not supported by the resource provider then the latest version for the resource provider will be used. 2017-10-9, latest, default.

* When resources are filtered by a tag name and value, the tags for each resource are not returned in the results.

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

resource_id
resource_group and name
name
resource_group, resource_provider and name
resource_group, resource_provider, resource_path and name
add_subscription_id, resource_uri and name
tag_name and tag_value

Different parameter combinations can be tried. If it is not supported, either the InSpec resource or the Azure Rest API will raise an error.

If the Azure Resource Manager endpoint returns multiple resources for a given query, this singular generic resource will fail. In that case, the plural generic resource should be used.

Properties

The properties that can be tested are dependent on the Azure Resource that is tested. One way to see what properties can be tested is checking their API pages. For example for virtual machines, see here. Also the Azure Resources Portal can be used to select the resource you are interested in and see what can be tested.

The following properties are applicable to almost all resources.

id: The unique resource identifier.
name: The name of the resource.
type: The resource type.
location: The location of the resource.
tags: The tag key:value pairs if defined on the resource.
properties: The resource properties.

For more properties, refer to specific Azure documents for the resource being tested.

Examples

Test Properties of a Virtual Machine and the Endpoint API Version.

describe azure_generic_resource(resource_group: 'my_vms', name: 'my_linux_vm') do
  its('properties.storageProfile.osDisk.osType') { should cmp 'Linux' }
  its('properties.storageProfile.osDisk.createOption') { should cmp 'FromImage' }
  its('properties.storageProfile.osDisk.name') { should cmp 'linux-external-osdisk' }
  its('properties.storageProfile.osDisk.caching') { should cmp 'ReadWrite' }

  its('api_version_used_for_query_state') { should eq 'latest' }
end

Test the API Version Used for the Query.

describe azure_generic_resource(resource_id: '/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Compute/virtualMachines/{vmName}', api_version: '2017-01-01') do
  its('api_version_used_for_query_state') { should eq 'user_provided' }
  its('api_version_used_for_query') { should eq '2017-01-01' }
end

Test the Tags if Include Specific Values.

describe azure_generic_resource(resource_group: 'my_vms', name: 'my_linux_vm') do
  its('tags') { should include(name: 'MyVM') }
**The tag key name can be tested in String or Symbol.**
**regardless of the value.**
**regardless of the value.**

end

Test Properties of a Virtual Machine Resides in an Azure Dev Test Lab .

describe azure_generic_resource(resource_provider: 'Microsoft.DevTestLab/labs', resource_path: '{labName}/virtualmachines', resource_group: 'my_group', name: 'my_VM') do
  its('properties.userName') { should cmp 'admin' }
  its('properties.allowClaim') { should cmp false }
end

Test a Resource Group .

describe azure_generic_resource(add_subscription_id: true, resource_uri: '/resourcegroups/', name: 'my_group') do
  it { should exist }
  its('tags') { should include(:owner) }
  its('tags') { should include(owner: 'John Doe') }
end

Test a Policy Definition.

describe azure_generic_resource(add_subscription_id: true, resource_uri: 'providers/Microsoft.Authorization/policyDefinitions', name: 'my_policy') do
  it { should exist }
  its('properties.policyRule.then.effect') { should cmp 'deny' }
  its('properties.policyType') { should cmp 'Custom' }
end

For more examples, please see the integration tests.

Matchers

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

exist

# Should not exist if there is no resource with a given name

describe azure_generic_resource(name: 'fake_name') do
  it { should_not exist }
