GRPCRoute.spec.rules[].matches[]

GRPCRouteMatch defines the predicate used to match requests to a given action. Multiple match types are ANDed together, i.e. the match will evaluate to true only if all conditions are satisfied. For example, the match below will match a gRPC request only if its service is `foo` AND it contains the `version: v1` header: ``` matches: - method: type: Exact service: "foo" - headers: name: "version" value "v1" ```

GRPCRoute.spec.rules[].matches[] fields and descriptions
Field / Type	Description
headers `object[]`	Headers specifies gRPC request header matchers. Multiple match values are ANDed together, meaning, a request MUST match all the specified headers to select the route. `maxItems: 16` `x-kubernetes-list-map-keys: ["name"]` `x-kubernetes-list-type: "map"`
method `object`	Method specifies a gRPC request service/method matcher. If this field is not specified, all services and methods will match. x-kubernetes-validations: [{"message":"One or both of 'service' or 'method' must be specified","rule":"has(self.type) ? has(self.service) \|\| has(self.method) : true"},{"message":"service must only contain valid characters (matching ^(?i)\\.?[a-z_][a-z_0-9](\\.[a-z_][a-z_0-9])$)","rule":"(!has(self.type) \|\| self.type == 'Exact') \u0026\u0026 has(self.service) ? self.service.matches(r\"\"\"^(?i)\\.?[a-z_][a-z_0-9](\\.[a-z_][a-z_0-9])$\"\"\"): true"},{"message":"method must only contain valid characters (matching ^[A-Za-z_][A-Za-z_0-9]$)","rule":"(!has(self.type) \|\| self.type == 'Exact') \u0026\u0026 has(self.method) ? self.method.matches(r\"\"\"^[A-Za-z_][A-Za-z_0-9]$\"\"\"): true"}]
