Gatewayclass
A GatewayClass is a cluster-scoped Kubernetes Gateway API resource defining a class of gateways managed by a particular controller.
Acing the Certified Kubernetes Administrator Exam, Second Edition
A GatewayClass is a cluster-scoped Gateway API resource that defines the controller responsible for implementing a class of gateways.
- How it is used
- Assigns Gateway implementations to controllers before Gateway listeners and route resources define traffic behavior.
- How deep it goes
- Defines cluster scope and controllerName, stopping short of listener, hostname, backend, or traffic-route configuration.
- Examples
- Uses example-class with controllerName example.com/gateway-controller and demonstrates selection from a Gateway resource.
- What you can do after
- Operate/configure a Gateway API controller class and associate Gateways with the correct implementation.

A GatewayClass is a Kubernetes Gateway API resource that defines a class of gateways managed by a particular controller and optionally associated parameters.
- How it is used
- Selects the controller and configuration model used when creating each Gateway entry point.
- How deep it goes
- Explains controllerName, optional parameters, and Gateway references, but stops short of detailing GatewayClass creation.
- Examples
- Uses kubectl listings, Istio's istio class, and a Gateway manifest with gatewayClassName: istio.
- What you can do after
- Operate/configure Gateways by listing available classes and setting gatewayClassName to the intended provider.
