About the google_service_account_keys Resource	gcp

google_service_account_keys

Use the google_service_account_keys InSpec audit resource to test properties of all, or a filtered group of, GCP service account keys.

Syntax

A google_service_account_keys resource block collects GCP service account keys by project then tests that group.

describe google_service_account_keys(service_account: 'projects/sample-project/serviceAccounts/[email protected]') do
  it { should exist }
end

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

google_service_account_keys(service_account: 'projects/sample-project/serviceAccounts/[email protected]').key_names.each do |sa_key_name|
  describe google_service_account_key(name: sa_key_name) do
    it { should exist }
    its('key_algorithm') { should eq "KEY_ALG_RSA_2048" }
  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 keys for the service account

describe google_service_account_keys(service_account: 'projects/sample-project/serviceAccounts/[email protected]') do
  its('count') { should be <= 1000}
end

Test that a service account with expected name is available

describe google_service_account_keys(service_account: 'projects/sample-project/serviceAccounts/[email protected]') do
  its('key_names'){ should include "projects/sample-project/serviceAccounts/[email protected]/keys/c6bd986da9fac6d71178db41d1741cbe751a5080" }
end
