An idiomatic C++ client library for theAnthos Multi-Cloud API. This API provides a way to manage Kubernetes clusters that run on AWS and Azure infrastructure. Combined with Connect, you can manage Kubernetes clusters on Google Cloud, AWS, and Azure from the Google Cloud Console. When you create a cluster with Anthos Multi-Cloud, Google creates the resources needed and brings up a cluster on your behalf. You can deploy workloads with the Anthos Multi-Cloud API or the gcloud and kubectl command-line tools.
While this library isGA, please note that the Google Cloud C++ client libraries donotfollowSemantic Versioning.
Quickstart
The following shows the code that you'll run in thegoogle/cloud/gkemulticloud/quickstart/directory, which should give you a taste of the Anthos Multi-Cloud API C++ client library API.
This library offers multiple*Clientclasses, 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*Clientclasses when testing your application.
