Cloud OS Login API C++ Client Library

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.

Retry, Backoff, and Idempotency Policies.

The library automatically retries requests that fail with transient errors, and uses exponential backoff to backoff between retries. Application developers can override the default policies.
