Version

This resource first became available in 1.0.0 of the inspec-azure resource pack.

Syntax

The resource_group must be given as a parameter.

describe azurerm_virtual_machines(resource_group: 'MyResourceGroup') do
  ...
end

Examples

# Exists if any virtual machines exist in the resource group
describe azurerm_virtual_machines(resource_group: 'MyResourceGroup') do
  it { should exist }
end

# Filters based on platform
describe azurerm_virtual_machines(resource_group: 'MyResourceGroup').where(platform: 'windows') do
  it { should exist }
end

Parameters

• resource_group

Parameter Examples

resource_group (required)

describe azurerm_virtual_machines(resource_group: 'MyResourceGroup') do
  ...
end

Filter Criteria

• platform
• name
• os_disk

platform

Filters the results to only include those that match the given platform. Valid choices are linux and windows.

# Insist that you have at least one windows virtual machine
describe azurerm_virtual_machines(resource_group: 'MyResourceGroup').where(platform: 'windows') do
  it { should exist }
end

name

Filters the result to only those that match the given name.

# Insist that you have at least one virtual machine that starts with 'MyVm'
describe azurerm_virtual_machines(resource_group: 'MyResourceGroup').where { name.start_with?('WindowsVm') } do
  it { should exist }
end

Attributes

• os_disks
• data_disks
• vm_names

os_disks

Gives a list of OS disk names for all the virtual machines in the resource group.

its('os_disks.sort') { should eq ['MyDisk1', 'MyDisk2'] }

data_disks

Gives a list of data disks for all the virtual machines in the resource group.

its('os_disks.sort') { should eq [['MyDisk1'], ['MyDisk2']] }

Note that it returns an array of arrays. You may flatten them for testing:

its('os_disks.flatten.sort') { should eq ['MyDisk1', 'MyDisk2'] }

vm_names

Gives a list of all the virtual machine names in the resource group.

its('vm_names') { should include('MyVm1', 'MyVm2') }

Matchers

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

exists

# Should not exist if no virtual machines are in the resource group
describe azurerm_virtual_machines(resource_group: 'MyResourceGroup') do
  it { should_not exist }
end

# Should exist if the filter returns a single virtual machine
describe azurerm_virtual_machines(resource_group: 'MyResourceGroup').where(platform: 'windows') do
  it { should exist }
end

Azure Permissions

Your ServicePrincipal must be setup with a contributor role on the subscription you wish to test.
