GKE Hub C++ Client Library

An idiomatic C++ client library for the GKE Hub , a service to handle the registration of many Kubernetes clusters to Google Cloud, and the management of multi-cluster features over those clusters.

While this library is GA, please note Google Cloud C++ client libraries do notfollow Semantic Versioning .

Quickstart

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

 #include "google/cloud/gkehub/v1/gke_hub_client.h"
#include "google/cloud/location.h"
#include <iostream>

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

  auto const location = google::cloud::Location(argv[1], "-");

  namespace gkehub = ::google::cloud::gkehub_v1;
  auto client = gkehub::GkeHubClient(gkehub::MakeGkeHubConnection());

  for (auto m : client.ListMemberships(location.FullName())) {
    if (!m) throw std::move(m).status();
    std::cout << m->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 gkehub_v1::GkeHubClient . All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock gkehub_v1::GkeHubClient when testing your application.
