GatewayClass.spec.parametersRef

ParametersRef is a reference to a resource that contains the configuration parameters corresponding to the GatewayClass. This is optional if the controller does not require any additional configuration. ParametersRef can reference a standard Kubernetes resource, i.e. ConfigMap, or an implementation-specific custom resource. The resource can be cluster-scoped or namespace-scoped. If the referent cannot be found, refers to an unsupported kind, or when the data within that resource is malformed, the GatewayClass SHOULD be rejected with the "Accepted" status condition set to "False" and an "InvalidParameters" reason. A Gateway for this GatewayClass may provide its own `parametersRef`. When both are specified, the merging behavior is implementation specific. It is generally recommended that GatewayClass provides defaults that can be overridden by a Gateway. Support: Implementation-specific
