An idiomatic C++ client library for theOrganization Policy API, a service to The Org Policy API allows users to configure governance rules on their GCP resources across the Cloud Resource Hierarchy.
While this library isGA, please note Google Cloud C++ client libraries donotfollowSemantic Versioning.
Quickstart
The following shows the code that you'll run in thegoogle/cloud/orgpolicy/quickstart/directory, which should give you a taste of the Organization Policy API C++ client library API.
#include "google/cloud/orgpolicy/v2/org_policy_client.h"
#include "google/cloud/project.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 2) {
std::cerr << "Usage: " << argv[0] << " project-id\n";
return 1;
}
namespace orgpolicy = ::google::cloud::orgpolicy_v2;
auto client =
orgpolicy::OrgPolicyClient(orgpolicy::MakeOrgPolicyConnection());
auto const project = google::cloud::Project(argv[1]);
for (auto p : client.ListPolicies(project.FullName())) {
if (!p) throw std::move(p).status();
std::cout << p->DebugString() << "\n";
}
return 0;
} catch (google::cloud::Status const& status) {
std::cerr << "google::cloud::Status thrown: " << status << "\n";
return 1;
}
Main classes
The main class in this library isorgpolicy_v2::OrgPolicyClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mockorgpolicy_v2::OrgPolicyClientwhen testing your application.
