Predicates are used in your
SpringCloudGatewayRouteConfig to match an incoming request to a route configuration, for example by matching on the request's HTTP Method, or URL path.
The open-source Spring Cloud Gateway project includes a number of built-in predicates that can be used in Spring Cloud Gateway for Kubernetes. For a complete list, see the Spring Cloud Gateway OSS documentation.
Spring Cloud Gateway for Kubernetes also provides custom predicates in addition to those included in the OSS project.
