GatewayClass Resource Configuration

This topic provides describes how to configure the GatewayClass resource, a generic Kubernetes gateway object used as a template for creating Gateway resources.

Introduction

The GatewayClass specification includes the name of the controller (controllerName) and an API object containing controller-specific configuration resources within the cluster (parametersRef). The value of the controllerName field must be set to hashicorp.com/consul-api-gateway-controller.

When gateways are created from a GatewayClass, they use the parameters specified in the GatewayClass at the time of instantiation.

The GatewayClass resource is a generic Kubernetes gateway object. For configuration specific to Consul API Gateway, refer to GatewayClassConfig.

Configuration model

The following outline shows how to format the configurations in the GatewayClass object. Click on a property name to view details about the configuration.

controllerName: string | required
parametersRef: object | optional
- group: string | required if parametersRef is set
- kind: string | required if parametersRef is set
- name: string | required if parametersRef is set
description: string | optional

Specification

This topic provides details about the configuration parameters.

controllerName

Specifies the name of the controller that manages the gateways generated by this class. The value must always be hashicorp.com/consul-api-gateway-controller.

Type: string
Required: required

parametersRef

Defines an API object that references additional configurations required by the gateway controller. The following table describes the fields that you must include in the parametersRef configuration.

Type: object
Required: optional

Parameter	Description	Type	Required
`group`	Specifies the Kubernetes group that the `parametersRef` is a member of. The value must always be `api-gateway.consul.hashicorp.com`. The `parametersRef.group` is always the same across all deployments of Consul API Gateway.	String	Required
`kind`	Specifies the type of Kubernetes object that the `parametersRef` configuration defines. The value must always be `GatewayClassConfig`. This `parametersRef.kind` is always the same across all deployments of Consul API Gateway.	String	Required
`name`	Specifies a name for the `GatewayClassConfig` object.	String	Required

description

Specifies a human-readable description of the gateway class. We recommend using the description field to describe the gateway class's purpose.

Type: string
Required: optional

Example Configuration

The following example creates a gateway class called example-gateway-class:

gateway.yaml

apiVersion: gateway.networking.k8s.io/v1alpha2
kind: GatewayClass
metadata:
  name: example-gateway-class
spec:
  controllerName: 'hashicorp.com/consul-api-gateway-controller'
  parametersRef:
    group: api-gateway.consul.hashicorp.com
    kind: GatewayClassConfig
    name: example-gateway-class-config
  description: The gateway class is for creating test gateways class configurations

Refer to the Kubernetes Gateway API documentation for details about configuring gateway classes.
