azure_generic_resources Resource

Use the azure_generic_resources Inspec audit resource to test any valid Azure resources.

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

This resource will interrogate all resources in your subscription available through Azure Resource Manager when initiated without a parameter.

describe azure_generic_resources do
  it { should exist }
end

Parameters

The following parameters can be passed for targeting Azure resources. All of them are optional.

resource_group: Azure resource group where the targeted resources have been created.; Example: MyResourceGroup
substring_of_resource_group: Substring of an Azure resource group name where the targeted resources have been created.; Example: RESOURCE_GROUP
name: Name of the Azure resources to test.; Example: VM_NAME
substring_of_name: Substring a name of the Azure resources to test.; Example: NAME
resource_provider: Azure resource provider of the resources to be tested.; Example: Microsoft.Compute/virtualMachines
tag_name<superscript>*</superscript>: Tag name defined on the Azure resources.; Example: name
tag_value: Tag value of the tag defined with the tag_name.; Example: external_linux
resource_uri: Azure REST API URI of the resources to be tested. This parameter should be used when resources do not reside in resource groups. It requires add_subscription_id parameter to be provided together.; Example: /providers/Microsoft.Authorization/policyDefinitions/
add_subscription_id: Indicates whether the resource_uri contains the subscription ID.; Example: true or false
filter_free_text: Filter expression for the endpoints supporting $filter parameter. For example, Azure role assignments. This can only be used with the resource_uri parameter.; Example: "atScope()" * 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_group
substring_of_resource_group
name
substring_of_name
substring_of_resource_group and substring_of_name
resource_provider
resource_group and resource_provider
substring_of_resource_group and resource_provider
tag_name
tag_name and tag_value
add_subscription_id and resource_uri
add_subscription_id, resource_uri and filter_free_text

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

It is advised to use these parameter sets to narrow down the targeted resources at the server side, Azure Rest API, for a more computing resource-efficient test.

Properties

ids: A list of the unique resource IDs.; Field: id
names: A list of the unique resource names within a resource group.; Field: name
tags: A list of tag:value pairs defined on the resources.; Field: tags
types: A list of resource types.; Field: type
locations: A list of locations where resources are created.; Field: location
created_times<superscript>**</superscript>: A list of created times of the resources.; Field: created_time
changed_times<superscript>**</superscript>: A list of changing times of the resources.; Field: changed_time
provisioning_states<superscript>**</superscript>: A list of provisioning states of the resources.; Field: provisioning_state

Note

For information on using filter criteria on plural resources, see the documentation on FilterTable

** These properties are not available when resource_uri is used.

Examples

Test all virtual machines in your subscription

describe azure_generic_resources(resource_provider: 'Microsoft.Compute/virtualMachines') do
  it { should exist }
  its('count') { should eq 43 }
end

Test all resources regardless of their type and resource group with a common string in names (Server Side Filtering)

azure_generic_resources(substring_of_name: 'project_a').ids.each do |id|
  describe azure_generic_resource(resource_id: id) do
    it { should exist }
    its('location') { should eq 'eastus' }
  end
end

Test all resources regardless of their type and resource group with a common tag ’name:value’ pair (Server Side Filtering)

azure_generic_resources(tag_name: 'demo', tag_value: 'shutdown_at_10_pm').ids.each do |id|
  describe azure_generic_resource(resource_id: id) do
    it { should exist }
    its('location') { should eq 'eastus' }
  end
end

Filters the results to only include those that match the given location (Client Side Filtering)

describe azure_generic_resources.where(location: 'eastus') do
  it { should exist }
end

Filters the results to only include those that created within last 24 hours (Client Side Filtering)

describe azure_generic_resources.where{ created_time > Time.now - 86400 } do
  it { should exist }
end

Test policy definitions

describe azure_generic_resources(add_subscription_id: true, resource_uri: 'providers/Microsoft.Authorization/policyDefinitions') do
  it { should exist }
end

Filter role assignments via ‘filter_free_text’

describe azure_generic_resources(add_subscription_id: true, resource_uri: "providers/Microsoft.Authorization/roleAssignments", filter_free_text: "atScope()+and+assignedTo('{abcd1234-abcd-1234}')") do
  it { should exist }
end

Matchers

For a full list of available matchers, see our Universal Matchers page.

This resource has the following special matchers.

exist

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

describe azure_generic_resources(resource_group: 'fake_group') do
  it { should_not exist }
end

not_exists

# Should exist if there is at least one resource.

describe azure_generic_resources(resource_group: 'RESOURCE_GROUP') do
  it { should exist }
end

Azure Permissions

Your Service Principal must be set up with at least a contributor role on the subscription you wish to test.
