Parameter Examples

The Resource Group as well as the Webapp name.

describe azurerm_webapp(resource_group: 'example', name: 'webapp_name') do
  it { should exist }
end

describe azurerm_webapp(resource_group: 'example', name: 'webapp_name').auth_settings do

end

Attributes

• id
• name
• location
• properties
• identity
• auth_settings
• configuration

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

control 'azurerm_webapp' do
  describe azurerm_webapp(resource_group: 'example', name: 'webapp_name') do
    it                                  { should exist }
    its('properties.enabled')           { should cmp true }
    its('properties.clientCertEnabled') { should cmp true }
    its('properties.enabledHostNames')  { should cmp 'webapp_name.azurewebsites.net' }
    its('properties.httpsOnly')         { should cmp true }
  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.

using_latest?(stack)

Asserts whether the deployed Azure WebApp is using the latest supported version of the given language/stack. Supported stacks (i.e. python, java, php, node) can be found in the properties section of WebApp Configuration documentation.

it { should be_using_latest('php') }
it { should be_using_latest('java') }
it { should be_using_latest('python') }
it { should be_using_latest('aspnet') }
it { should be_using_latest('dotnetcore') }

exists

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

# If we expect 'webapp_name' to have a Managed Service Identity
describe azurerm_webapp(resource_group: 'example', name: 'webapp_name') do
  it { should have_identity }
end
