Binary Authorization is a system providing policy control for images deployed to Kubernetes Engine clusters.

While this library is **GA** , please note Google Cloud C++ client libraries do **not** follow [Semantic Versioning](https://semver.org/).

### Quickstart

The following shows the code that you'll run in the `google/cloud/binaryauthorization/quickstart/` directory, which should give you a taste of the Binary Authorization API C++ client library API.

    #include "google/cloud/binaryauthorization/v1/binauthz_management_service_v1_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 binaryauthorization = ::google::cloud::binaryauthorization_v1;
      auto client = binaryauthorization::BinauthzManagementServiceV1Client(
          binaryauthorization::MakeBinauthzManagementServiceV1Connection());

      auto const project = google::cloud::Project(argv[1]);
      for (auto a : client.ListAttestors(project.FullName())) {
        if (!a) throw std::move(a).status();
        std::cout << a->DebugString() << "\n";
      }

      return 0;
    } catch (google::cloud::Status const& status) {
      std::cerr << "google::cloud::Status thrown: " << status << "\n";
      return 1;
    }

### Main classes

This library offers multiple `*Client` classes, which are listed below. Each one of these classes exposes all the RPCs for a service as member functions of the class. This library groups multiple services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.

The library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the `*Client` classes when testing your application.
