Google Cloud IAM C++ Client Library

This directory contains an idiomatic C++ client library for interacting with Cloud IAM.

Please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.

Supported Platforms

  • Windows, macOS, Linux
  • C++11 (and higher) compilers (we test with GCC >= 5.4, Clang >= 6.0, and MSVC >= 2019)
  • Environments with or without exceptions
  • Bazel and CMake builds

Documentation

Quickstart

The quickstart/ directory contains a minimal environment to get started using this client library in a larger project. The following "Hello World" program is used in this quickstart, and should give you a taste of this library.

#include "google/cloud/iam/iam_client.h"
#include <iostream>
#include <stdexcept>

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

  std::string const project_id = argv[1];

  // Create a namespace alias to make the code easier to read.
  namespace iam = google::cloud::iam;
  iam::IAMClient client(iam::MakeIAMConnection());
  std::cout << "Service Accounts for project: " << project_id << "\n";
  int count = 0;
  for (auto const& service_account :
       client.ListServiceAccounts("projects/" + project_id)) {
    if (!service_account) {
      throw std::runtime_error(service_account.status().message());
    }
    std::cout << service_account->name() << "\n";
    ++count;
  }

  if (count == 0) std::cout << "No Service Accounts found.\n";
  return 0;
} catch (std::exception const& ex) {
  std::cerr << "Standard exception raised: " << ex.what() << "\n";
  return 1;
}
  • Packaging maintainers or developers that prefer to install the library in a fixed directory (such as /usr/local or /opt) should consult the packaging guide.
  • Developers wanting to use the libraries as part of a larger CMake or Bazel project should consult the quickstart guides for the library or libraries they want to use.
  • Developers wanting to compile the library just to run some of the examples or tests should read the current document.
  • Contributors and developers to google-cloud-cpp should consult the guide to setup a development workstation.

Installation

Please consult the packaging guide for detailed instructions to install the Google Cloud C++ client libraries. If your project uses CMake or Bazel check the quickstart example for instructions to use this library in your project.
