Kubernetes Gateway API

Jan 1, 0001

Definition

The Kubernetes Gateway API is an evolving set of resources and configurations designed to enhance the management of network traffic in Kubernetes clusters. It aims to provide a more expressive and extensible model for defining ingress and egress traffic policies, supporting advanced use cases like traffic splitting, header-based routing, and more. The Gateway API is intended to replace the Ingress API, offering improved scalability and flexibility for service networking.
