the capability to match requests by hostname, gRPC service, gRPC method,
or HTTP/2 header. 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).
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\".

HTTP/1, i.e. without prior knowledge. \n Support: Extended"

description: "Hostnames defines a set of hostnames to match against

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:

parentRefs:
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. \n The only kind of parent resource
with \"Core\" support is Gateway. This API may be extended in the
future to support additional kinds of parent resources such as one
of the route kinds. \n It is invalid to reference an identical parent
more than once. It is valid to reference multiple distinct sections
within the same parent resource, such as 2 Listeners within a Gateway.
\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 any other
kind of cross-namespace reference."

be ignored. Due to the case-insensitivity
of header names, \"foo\" and \"Foo\" are considered
equivalent."
