Filters can be used to specify additional processing steps. Backends specify where matching requests will be routed. \n GRPCRoute falls under extended support within the Gateway API. Within the following specification, the word \"MUST\" indicates that an implementation supporting GRPCRoute must conform to the indicated requirement, but an implementation not supporting this route type need not follow the requirement unless explicitly indicated. \n Implementations supporting `GRPCRoute` with the `HTTPS` `ProtocolType` MUST accept HTTP/2 connections without an initial upgrade from HTTP/1.1, i.e. via ALPN. If the implementation does not support this, then it MUST set the \"Accepted\" condition to \"False\" for the affected listener with a reason of \"UnsupportedProtocol\". Implementations MAY also accept HTTP/2 connections with an upgrade from HTTP/1. \n Implementations supporting `GRPCRoute` with the `HTTP` `ProtocolType` MUST support HTTP/2 over cleartext TCP (h2c, https://www.rfc-editor.org/rfc/rfc7540#section-3.1) without an initial upgrade from HTTP/1.1, i.e. with prior knowledge (https://www.rfc-editor.org/rfc/rfc7540#section-3.4).

This matches the RFC 1123 definition of a hostname with 2 notable exceptions: \n 1. IPs are not allowed. 2. A hostname may be prefixed with a wildcard label (`*.`). The wildcard label MUST appear by itself as the first label. \n If a hostname is specified by both the Listener and GRPCRoute, there MUST be at least one intersecting hostname for the GRPCRoute to be attached to the Listener. For example: \n * A Listener with `test.example.com` as the hostname matches GRPCRoutes that have either not specified any hostnames, or have specified at least one of `test.example.com` or `*.example.com`. * A Listener with `*.example.com` as the hostname matches GRPCRoutes that have either not specified any hostnames or have specified at least one hostname that matches the Listener hostname. For example, `test.example.com` and `*.example.com` would both match. On the other hand, `example.com` and `test.example.net` would not match. \n Hostnames that are prefixed with a wildcard label (`*.`) are interpreted as a suffix match. That means that a match for `*.example.com` would match both `test.example.com`, and `foo.test.example.com`, but not `example.com`. \n If both the Listener and GRPCRoute have specified hostnames, any GRPCRoute hostnames that do not match the Listener hostname MUST be ignored. For example, if a Listener specified `*.example.com`, and the GRPCRoute specified `test.example.com` and `test.example.net`, `test.example.net` MUST NOT be considered for a match. \n If both the Listener and GRPCRoute have specified hostnames, and none match with the criteria above, then the GRPCRoute MUST NOT be accepted by the implementation. The implementation MUST raise an 'Accepted' Condition with a status of `False` in the corresponding RouteParentStatus. \n If a Route (A) of type HTTPRoute or GRPCRoute is attached to a Listener and that listener already has another Route (B) of the other type attached and the intersection of the hostnames of A and B is non-empty, then the implementation MUST accept exactly one of these two routes, determined by the following criteria, in order: \n * The oldest Route based on creation timestamp. * The Route appearing first in alphabetical order by \"{namespace}/{name}\". \n The rejected Route MUST raise an 'Accepted' condition with a status of 'False' in the corresponding RouteParentStatus. \n Support: Core",

"description": "ParentRefs references the resources (usually Gateways) that a Route wants to be attached to. Note that the referenced parent resource needs to allow this for the attachment to be complete. For Gateways, that means the Gateway needs to allow attachment from Routes of this kind and namespace. For Services, that means the Service must either be in the same namespace for a \"producer\" route, or the mesh implementation must support and allow \"consumer\" routes for the referenced Service. ReferenceGrant is not applicable for governing ParentRefs to Services - it is not possible to create a \"producer\" route for a Service in a different namespace from the Route. \n There are two kinds of parent resources with \"Core\" support: \n * Gateway (Gateway conformance profile) * Service (Mesh conformance profile, experimental, ClusterIP Services only) This API may be extended in the future to support additional kinds of parent resources. \n ParentRefs must be _distinct_. This means either that: \n * They select different objects. If this is the case, then parentRef entries are distinct. In terms of fields, this means that the multi-part key defined by `group`, `kind`, `namespace`, and `name` must be unique across all parentRef entries in the Route. * They do not select different objects, but for each optional field used, each ParentRef that selects the same object must set the same set of optional fields to different values. If one ParentRef sets a combination of optional fields, all must set the same combination. \n Some examples: \n * If one ParentRef sets `sectionName`, all ParentRefs referencing the same object must also set `sectionName`. * If one ParentRef sets `port`, all ParentRefs referencing the same object must also set `port`. * If one ParentRef sets `sectionName` and `port`, all ParentRefs referencing the same object must also set `sectionName` and `port`. \n It is possible to separately reference multiple distinct objects that may be collapsed by an implementation. For example, some implementations may choose to merge compatible Gateway Listeners together. If that is the case, the list of routes attached to those resources should also be merged. \n Note that for ParentRefs that cross namespace boundaries, there are specific rules. Cross-namespace references are only valid if they are explicitly allowed by something in the namespace they are referring to. For example, Gateway has the AllowedRoutes field, and ReferenceGrant provides a generic way to enable other kinds of cross-namespace reference. \n ParentRefs from a Route to a Service in the same namespace are \"producer\" routes, which apply default routing rules to inbound connections from any namespace to the Service. \n ParentRefs from a Route to a Service in a different namespace are \"consumer\" routes, and these routing rules are only applied to outbound connections originating from the same namespace as the Route, for which the intended destination of the connections are a Service targeted as a ParentRef of the Route. \n ",

"description": "Matches define conditions used for matching the rule against incoming gRPC requests. Each match is independent, i.e. this rule will be matched if **any** one of the matches is satisfied. \n For example, take the following matches configuration: \n ``` matches: - method: service: foo.bar headers: values: version: 2 - method: service: foo.bar.v2 ``` \n For a request to match against this rule, it MUST satisfy EITHER of the two conditions: \n - service of foo.bar AND contains the header `version: 2` - service of foo.bar.v2 \n See the documentation for GRPCRouteMatch on how to specify multiple match conditions to be ANDed together. \n If no matches are specified, the implementation MUST match every gRPC request. \n Proxy or Load Balancer routing configuration generated from GRPCRoutes MUST prioritize rules based on the following criteria, continuing on ties. Merging MUST not be done between GRPCRoutes and HTTPRoutes. Precedence MUST be given to the rule with the largest number of: \n * Characters in a matching non-wildcard hostname. * Characters in a matching hostname. * Characters in a matching service. * Characters in a matching method. * Header matches. \n If ties still exist across multiple Routes, matching precedence MUST be determined in order of the following criteria, continuing on ties: \n * The oldest Route based on creation timestamp. * The Route appearing first in alphabetical order by \"{namespace}/{name}\". \n If ties still exist within the Route that has been given precedence, matching precedence MUST be granted to the first matching rule meeting the above criteria.",
