Connect Gateway API C++ Client Library

This directory contains an idiomatic C++ client library for the Connect Gateway API.

The Connect Gateway service allows connectivity from external parties to connected Kubernetes clusters.

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

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/gkeconnect/gateway/v1/gateway_control_client.h"
#include "google/cloud/gkeconnect/gateway/v1/gateway_control_rest_connection.h"
#include "google/cloud/location.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 4) {
    std::cerr << "Usage: " << argv[0]
              << " project-id location-id membership-id\n";
    return 1;
  }

  auto const location = google::cloud::Location(argv[1], argv[2]);

  namespace gkeconnect = ::google::cloud::gkeconnect_gateway_v1;
  auto client = gkeconnect::GatewayControlClient(
      gkeconnect::MakeGatewayControlConnectionRest());

  google::cloud::gkeconnect::gateway::v1::GenerateCredentialsRequest request;
  request.set_name(location.FullName() + "/memberships/" + argv[3]);

  auto response = client.GenerateCredentials(request);
  if (!response) throw std::move(response).status();
  std::cout << response->DebugString() << "\n";

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