google_compute_vpn_tunnels

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


Syntax

A google_compute_vpn_tunnels resource block collects GCP vpn_tunnels by project and region, then tests that group.

describe google_compute_vpn_tunnels(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_vpn_tunnel.

google_compute_vpn_tunnels(project: 'chef-inspec-gcp', region:'europe-west2').vpn_tunnel_names.each do |vpn_tunnel_name|
  describe google_compute_vpn_tunnel(project: 'chef-inspec-gcp', region: 'europe-west2', name: vpn_tunnel_name) do
    its('creation_timestamp_date') { should be > Time.now - 365*60*60*24*10 }
    its('target_vpn_gateway') { should match /gateway_name/ }
    its('remote_traffic_selector') { should include "0.0.0.0/0" }
    its('status') { should_not eq "ESTABLISHED" }
  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 vpn_tunnels available for the project and region

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

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

describe google_compute_vpn_tunnels(project: 'chef-inspec-gcp', region: 'europe-west2') do
  its('vpn_tunnel_names') { should include "vpn_tunnel-name" }
end

Test that an expected vpntunnel targetvpn_gateways name is not present for the project and region

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


Filter Criteria

This resource supports the following filter criteria: vpn_tunnel_name and vpn_tunnel_target_vpn_gateway. Any of these may be used with where, as a block or as a method.

Properties

  • vpn_tunnel_names - an array of googlecomputevpn_tunnel name strings
  • vpn_tunnel_target_vpn_gateway - an array of googlecomputetargetvpngateway name strings


GCP Permissions

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