 Kubernetes resources and "records of intent" are all stored as API objects, and modified via RESTful calls to the API. The API allows configuration to be managed in a declarative way. Users can interact with the Kubernetes API directly, or via tools like `kubectl`. The core Kubernetes API is flexible and can also be extended to support custom resources.

+核心的 Kubernetes API 是很灵活的，可以扩展以支持定制资源。
