  it { should exist }
end

Test that a specified AKS cluster was successfully provisioned

describe azurerm_network_security_group(resource_group: 'example', name: 'ClusterName') do
  its('properties.provisioningState') { should cmp 'Succeeded' }
end

Test that a specified AKS cluster the correct number of nodes in pool

describe azurerm_network_security_group(resource_group: 'example', name: 'ClusterName') do
  its('properties.agentPoolProfiles.first.count') { should cmp 5 }
end

Parameters

• name
• resource_group

Parameter Examples

The Resource Group as well as the AKS Cluster name.

  it { should exist }
end

Attributes

All of the attributes are avialable via dot notation. This is an example of the currently available attributes.

control 'azurerm_aks_cluster' do
  describe azurerm_aks_cluster(resource_group: 'example', name: 'ClusterName') do
    it { should exist }
    its('properties.provisioningState') { should cmp 'Succeeded' }
    its('properties.kubernetesVersion') { should cmp '1.11.3' }
    its('properties.dnsPrefix') { should cmp 'ClusterName' }
    its('properties.fqdn') { should cmp 'ClusterName' }
    its('properties.agentPoolProfiles.first.name') { should cmp 'agentpool' }
    its('properties.agentPoolProfiles.first.count') { should cmp 3 }
    its('properties.agentPoolProfiles.first.vmSize') { should cmp 'Standard_DS2_V2' }
    its('properties.agentPoolProfiles.first.storageProfile') { should cmp 'ManagedDisks' }
    its('properties.agentPoolProfiles.first.maxPods') { should cmp 110 }
    its('properties.agentPoolProfiles.first.osType') { should cmp 'Linux' }
  end
end

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

The control will pass if the resource returns a result. Use should_not if you expect zero matches.

# If we expect 'ClusterName' to always exist
describe azurerm_aks_cluster(resource_group: 'example', name: 'ClusterName') do
  it { should exist }
end

# If we expect 'ClusterName' to never exist
describe azurerm_aks_cluster(resource_group: 'example', name: 'ClusterName') do
  it { should_not exist }
end
