This directory contains an idiomatic C++ client library for Cloud Run, a managed compute platform that lets you run containers directly on top of Google's scalable infrastructure.
Note that this library only provides tools to manage Cloud Run resources. To actually deploy a C++ function to Cloud Run, see the Cloud Run for C++ Hello World example, which uses the C++ Functions Framework library.
While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.
Quickstart
The following shows the code that you'll run in the google/cloud/run/quickstart/ directory, which should give you a taste of the Cloud Run Admin API C++ client library API.
#include "google/cloud/run/v2/services_client.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 3) {
std::cerr << "Usage: " << argv[0] << " project-id location-id\n";
return 1;
}
namespace run = ::google::cloud::run_v2;
auto client = run::ServicesClient(run::MakeServicesConnection());
auto const parent =
std::string{"projects/"} + argv[1] + "/locations/" + argv[2];
for (auto r : client.ListServices(parent)) {
if (!r) throw std::move(r).status();
std::cout << r->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 gRPC service as member functions of the class. This library groups multiple gRPC 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.
The library automatically retries requests that fail with transient errors, and uses exponential backoff to backoff between retries. Application developers can override the default policies.
