An idiomatic C++ client library forCloud Composer, a service that manages Apache Airflow environments on Google Cloud Platform.

While this library isGA, please note Google Cloud C++ client libraries donot followSemantic Versioning.

Quickstart

The following shows the code that you'll run in thegoogle/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;}

Main classes

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.

• composer_v1::EnvironmentsClient
• composer_v1::ImageVersionsClient
