Gateway API（之前叫 Service API）是由 SIG-NETWORK 社区管理的开源项目，项目地址
Ingress 资源对象不能很好的满足网络需求，很多场景下 Ingress 控制器都需要通过定义 annotations 或者 crd 来进行功能扩展，这对于使用标准和支持是非常不利的，新推出的 Gateway API 旨在通过可扩展的面向角色的接口来增强服务网络。
Gateway API 是 Kubernetes 中的一个 API 资源集合，包括 GatewayClass、Gateway、HTTPRoute、TCPRoute、Service 等，这些资源共同为各种网络用例构建模型。
