google_compute_subnetworks

Use the google_compute_subnetworks InSpec audit resource to test properties of all, or a filtered group of, GCP compute subnetworks for a project and region.


Syntax

A google_compute_subnetworks resource block collects GCP subnetworks by project and region, then tests that group.

describe google_compute_subnetworks(project: 'chef-inspec-gcp', region: 'europe-west2') do
  it { should exist }
end

Use this InSpec resource to enumerate IDs then test in-depth using google_compute_subnetwork.

google_compute_subnetworks(project: 'chef-inspec-gcp', region:'europe-west2').subnetwork_names.each do |subnetwork_name|
  describe google_compute_subnetwork(project: 'chef-inspec-gcp', region: 'europe-west2', name: name: subnetwork_name) do
    its('creation_timestamp_date') { should be > Time.now - 365*60*60*24*10 }
    its('ip_cidr_range') { should eq "10.2.0.0/29" }
    its('network') { should match "gcp_network_name" }
    its('private_ip_google_access') { should be false }
  end
end


Examples

The following examples show how to use this InSpec audit resource.

Test that there are no more than a specified number of subnetworks available for the project and region

describe google_compute_subnetworks(project: 'chef-inspec-gcp', region: 'europe-west2') do
  its('count') { should be <= 100}
end

Test that an expected subnetwork identifier is present in the project and region

describe google_compute_subnetworks(project: 'chef-inspec-gcp', region: 'europe-west2') do
  its('subnetwork_ids') { should include 12345678975432 }
end

Test that an expected subnetwork name is available for the project and region

describe google_compute_subnetworks(project: 'chef-inspec-gcp', region: 'europe-west2') do
  its('subnetwork_names') { should include "subnetwork-name" }
end

Test that an expected subnetwork network name is not present for the project and region

describe google_compute_subnetworks(project: 'chef-inspec-gcp', region: 'europe-west2') do
  its('subnetwork_networks') { should not include "network-name" }
end


Filter Criteria

This resource supports the following filter criteria: subnetwork_id; subnetwork_name; enable_flow_logs and subnetwork_network. Any of these may be used with where, as a block or as a method.

Properties

  • subnetwork_ids - an array of googlecomputesubnetwork identifier integers
  • subnetwork_names - an array of googlecomputesubnetwork name strings
  • subnetwork_networks - an array of googlecomputenetwork name strings
  • enable_flow_logs - an array of enableflowlog booleans


GCP Permissions

Ensure the Compute Engine API is enabled for the project where the resource is located.
