An idiomatic C++ client library for the Cloud OS Login API, a service you can use to manage access to your VM instances using IAM roles.

While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

The following shows the code that you'll run in the google/cloud/oslogin/quickstart/ directory, which should give you a taste of the Cloud OS Login API C++ client library API.

#include "google/cloud/oslogin/v1/os_login_client.h"
#include <iostream>
#include <string>

int main(int argc, char* argv[]) try {
  if (argc != 2) {
    std::cerr << "Usage: " << argv[0] << " user\n";
    return 1;
  }

  namespace oslogin = ::google::cloud::oslogin_v1;
  auto client =
      oslogin::OsLoginServiceClient(oslogin::MakeOsLoginServiceConnection());

  auto const name = "users/" + std::string{argv[1]};
  auto lp = client.GetLoginProfile(name);
  if (!lp) throw std::move(lp).status();
  std::cout << lp->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 is oslogin_v1::OsLoginServiceClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock oslogin_v1::OsLoginServiceClient when testing your application.
