the capability to match requests by hostname, gRPC service, gRPC method,

|
|
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).

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}\".

It can be interpreted differently based on the type of
|
|
parent resource. \n When the parent resource is a Gateway,
|
|
this targets all listeners listening on the specified
|
|
port that also support this kind of Route(and select this
|
|
Route). It's not recommended to set `Port` unless the
|
|
networking behaviors specified in a Route must apply to
|
|
a specific port as opposed to a listener(s) whose port(s)
|
|
may be changed. When both Port and SectionName are specified,
|
|
the name and port of the selected listener must match
|
|
both specified values. \n Implementations MAY choose to
|
|
support other parent resources. Implementations supporting
|
|
other types of parent resources MUST clearly document
|
|
how/if Port is interpreted. \n For the purpose of status,
|
|
an attachment is considered successful as long as the
|
|
parent resource accepts it partially. For example, Gateway
|
|
listeners can restrict which Routes can attach to them
|
|
by Route kind, namespace, or hostname. If 1 of 2 Gateway
|
|
listeners accept attachment from the referencing Route,
|
|
the Route MUST be considered successfully attached. If
|
|
no Gateway listeners accept attachment from this Route,
|
|
the Route MUST be considered detached from the Gateway.

description: "SectionName is the name of a section within

is interpreted as the following: \n * Gateway: Listener

Name. When both Port (experimental) and SectionName are

If that is the case, they MUST clearly document how SectionName
|
|
is interpreted. \n When unspecified (empty string), this

|
will reference the entire resource. For the purpose of

status, an attachment is considered successful if at least

one section in the parent resource accepts it. For example,

|
Gateway listeners can restrict which Routes can attach

to them by Route kind, namespace, or hostname. If 1 of

If no Gateway listeners accept attachment from this Route,
