An idiomatic C++ client library for theGKE 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 isGA, please note Google Cloud C++ client libraries donotfollowSemantic Versioning.
Quickstart
The following shows the code that you'll run in thegoogle/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 isgkehub_v1::GkeHubClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mockgkehub_v1::GkeHubClientwhen testing your application.
