Gateway API

The Kubernetes successor to Ingress providing role-oriented, extensible resources such as GatewayClass, Gateway, and HTTPRoute.

Definition

Gateway API separates infrastructure provider, cluster operator, and app developer roles, and supports traffic splitting, header matching, and multiple protocols. Service meshes also implement it.

Example

An HTTPRoute sends 90% of traffic to v1 and 10% to v2 backends.

Exam tip

Gateway API adds native weighted traffic splitting that Ingress lacks.
