An idiomatic C++ client library for Cloud Composer, a service that manages Apache Airflow environments on Google Cloud Platform.
While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.
QuickstartThe following shows the code that you'll run in the google/cloud/composer/quickstart/ directory, which should give you a taste of the Cloud Composer C++ client library API.
#include "google/cloud/composer/v1/environments_client.h"
#include "google/cloud/location.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;
}
auto const location = google::cloud::Location(argv[1], argv[2]);
namespace composer = ::google::cloud::composer_v1;
auto client =
composer::EnvironmentsClient(composer::MakeEnvironmentsConnection());
for (auto e : client.ListEnvironments(location.FullName())) {
if (!e) throw std::move(e).status();
std::cout << e->DebugString() << "\n";
}
return 0;
} catch (google::cloud::Status const& status) {
std::cerr << "google::cloud::Status thrown: " << status << "\n";
return 1;
}
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.
