Kubernetes Gateway API
Kubernetes Gateway API is an evolution of the Ingress API that provides more flexibility, expressiveness, and extensibility for managing service traffic within Kubernetes clusters.
Key Features1.
Role-Based Model: Unlike Ingress, Gateway API introduces clear separation of concerns by defining different roles such as GatewayClass, Gateway, HTTPRoute, and TCPRoute.
2.
Multiple Listeners: Gateways can support multiple listeners on different ports and protocols.
3.
Cross-Namespace Routing: Allows defining routing policies across different namespaces, improving multi-tenant support.
4.
Service Mesh Integration: Can be used alongside service meshes for advanced traffic control.
5.
More Extensible than Ingress: Supports different route types, making it adaptable for various protocols beyond just HTTP.
Core API Resources1. GatewayClass: Defines a high-level abstraction for load balancers and network configurations.
2.
Gateway: Represents an instance of a GatewayClass, defining how traffic should be handled.
3.
HTTPRoute: Specifies routing rules for HTTP traffic.
4.
TCPRoute, UDPRoute, GRPCRoute: Define routing for non-HTTP protocols.
5.
ReferenceGrant: Allows controlled cross-namespace resource references.
