listeners:
description: |-
Listeners associated with this Gateway. Listeners define
logical endpoints that are bound on this Gateway's addresses.
At least one Listener MUST be specified.
Each Listener in a set of Listeners (for example, in a single Gateway)
MUST be _distinct_, in that a traffic flow MUST be able to be assigned to
exactly one listener. (This section uses "set of Listeners" rather than
"Listeners in a single Gateway" because implementations MAY merge configuration
from multiple Gateways onto a single data plane, and these rules _also_
apply in that case).
Practically, this means that each listener in a set MUST have a unique
combination of Port, Protocol, and, if supported by the protocol, Hostname.
Some combinations of port, protocol, and TLS settings are considered
Core support and MUST be supported by implementations based on their
targeted conformance profile:
HTTP Profile
1. HTTPRoute, Port: 80, Protocol: HTTP
2. HTTPRoute, Port: 443, Protocol: HTTPS, TLS Mode: Terminate, TLS keypair provided
TLS Profile
1. TLSRoute, Port: 443, Protocol: TLS, TLS Mode: Passthrough
"Distinct" Listeners have the following property:
The implementation can match inbound requests to a single distinct
Listener. When multiple Listeners share values for fields (for
example, two Listeners with the same Port value), the implementation
can match requests to only one of the Listeners using other
Listener fields.
For example, the following Listener scenarios are distinct:
1. Multiple Listeners with the same Port that all use the "HTTP"
Protocol that all have unique Hostname values.
2. Multiple Listeners with the same Port that use either the "HTTPS" or
"TLS" Protocol that all have unique Hostname values.
3. A mixture of "TCP" and "UDP" Protocol Listeners, where no Listener
with the same Protocol has the same Port value.
Some fields in the Listener struct have possible values that affect
whether the Listener is distinct. Hostname is particularly relevant
for HTTP or HTTPS protocols.
When using the Hostname value to select between same-Port, same-Protocol
Listeners, the Hostname value must be different on each Listener for the
Listener to be distinct.
When the Listeners are distinct based on Hostname, inbound request
hostnames MUST match from the most specific to least specific Hostname
values to choose the correct Listener and its associated set of Routes.
Exact matches must be processed before wildcard matches, and wildcard
matches must be processed before fallback (empty Hostname value)
matches. For example, `"foo.example.com"` takes precedence over
`"*.example.com"`, and `"*.example.com"` takes precedence over `""`.
Additionally, if there are multiple wildcard entries, more specific
wildcard entries must be processed before less specific wildcard entries.
For example, `"*.foo.example.com"` takes precedence over `"*.example.com"`.
The precise definition here is that the higher the number of dots in the
hostname to the right of the wildcard character, the higher the precedence.
The wildcard character will match any number of characters _and dots_ to
the left, however, so `"*.example.com"` will match both
`"foo.bar.example.com"` _and_ `"bar.example.com"`.
If a set of Listeners contains Listeners that are not distinct, then those
Listeners are Conflicted, and the implementation MUST set the "Conflicted"
condition in the Listener Status to "True".
Implementations MAY choose to accept a Gateway with some Conflicted
Listeners only if they only accept the partial Listener set that contains
no Conflicted Listeners. To put this another way, implementations may
accept a partial Listener set only if they throw out *all* the conflicting
Listeners. No picking one of the conflicting listeners as the winner.
This also means that the Gateway must have at least one non-conflicting
Listener in this case, otherwise it violates the requirement that at
least one Listener must be present.
The implementation MUST set a "ListenersNotValid" condition on the
Gateway Status when the Gateway contains Conflicted Listeners whether or
not they accept the Gateway. That Condition SHOULD clearly
indicate in the Message which Listeners are conflicted, and which are
Accepted. Additionally, the Listener status for those listeners SHOULD
indicate which Listeners are conflicted and not Accepted.
A Gateway's Listeners are considered "compatible" if:
1. They are distinct.
2. The implementation can serve them in compliance with the Addresses
requirement that all Listeners are available on all assigned
addresses.
Compatible combinations in Extended support are expected to vary across
implementations. A combination that is compatible for one implementation
may not be compatible for another.
For example, an implementation that cannot serve both TCP and UDP listeners
on the same address, or cannot mix HTTPS and generic TLS listens on the same port
would not consider those cases compatible, even though they are distinct.
Note that requests SHOULD match at most one Listener. For example, if
Listeners are defined for "foo.example.com" and "*.example.com", a
request to "foo.example.com" SHOULD only be routed using routes attached
to the "foo.example.com" Listener (and not the "*.example.com" Listener).
This concept is known as "Listener Isolation". Implementations that do
not support Listener Isolation MUST clearly document this.
Implementations MAY merge separate Gateways onto a single set of
Addresses if all Listeners across all Gateways are compatible.

description: |-
AllowedRoutes defines the types of routes that MAY be attached to a
Listener and the trusted namespaces where those Route resources MAY be

Although a client request may match multiple route rules, only one rule
may ultimately receive the request. Matching precedence MUST be
determined in order of the following criteria:
* The most specific match as defined by the Route type.
* The oldest Route based on creation timestamp. For example, a Route with
a creation timestamp of "2020-09-08 01:02:03" is given precedence over
a Route with a creation timestamp of "2020-09-08 01:02:04".
* If everything else is equivalent, the Route appearing first in
alphabetical order (namespace/name) should be given precedence. For
example, foo/bar is given precedence over foo/baz.
All valid rules within a Route attached to this Listener should be
implemented. Invalid Route rules can be ignored (sometimes that will mean
the full Route). If a Route rule transitions from valid to invalid,
support for that Route rule should be dropped to ensure consistency. For
example, even if a filter specified by a Route rule is invalid, the rest
of the rules within that Route should still be supported.

Hostname specifies the virtual hostname to match for protocol types that

Implementations MUST apply Hostname matching appropriately for each of
the following protocols:
* TLS: The Listener Hostname MUST match the SNI.
* HTTP: The Listener Hostname MUST match the Host header of the request.
* HTTPS: The Listener Hostname SHOULD match at both the TLS and HTTP
protocol layers as described above. If an implementation does not
ensure that both the SNI and Host header match the Listener hostname,
it MUST clearly document that.
For HTTPRoute and TLSRoute resources, there is an interaction with the
`spec.hostnames` array. When both listener and route specify hostnames,
there MUST be an intersection between the values for a Route to be
accepted. For more information, refer to the Route specific Hostnames
documentation.
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`.

listeners:
description: |-
Listeners associated with this Gateway. Listeners define
logical endpoints that are bound on this Gateway's addresses.
At least one Listener MUST be specified.
Each Listener in a set of Listeners (for example, in a single Gateway)
MUST be _distinct_, in that a traffic flow MUST be able to be assigned to
exactly one listener. (This section uses "set of Listeners" rather than
"Listeners in a single Gateway" because implementations MAY merge configuration
from multiple Gateways onto a single data plane, and these rules _also_
apply in that case).
Practically, this means that each listener in a set MUST have a unique
combination of Port, Protocol, and, if supported by the protocol, Hostname.
Some combinations of port, protocol, and TLS settings are considered
Core support and MUST be supported by implementations based on their
targeted conformance profile:
HTTP Profile
1. HTTPRoute, Port: 80, Protocol: HTTP
2. HTTPRoute, Port: 443, Protocol: HTTPS, TLS Mode: Terminate, TLS keypair provided
TLS Profile
1. TLSRoute, Port: 443, Protocol: TLS, TLS Mode: Passthrough
"Distinct" Listeners have the following property:
The implementation can match inbound requests to a single distinct
Listener. When multiple Listeners share values for fields (for
example, two Listeners with the same Port value), the implementation
can match requests to only one of the Listeners using other
Listener fields.
For example, the following Listener scenarios are distinct:
1. Multiple Listeners with the same Port that all use the "HTTP"
Protocol that all have unique Hostname values.
2. Multiple Listeners with the same Port that use either the "HTTPS" or
"TLS" Protocol that all have unique Hostname values.
3. A mixture of "TCP" and "UDP" Protocol Listeners, where no Listener
with the same Protocol has the same Port value.
Some fields in the Listener struct have possible values that affect
whether the Listener is distinct. Hostname is particularly relevant
for HTTP or HTTPS protocols.
When using the Hostname value to select between same-Port, same-Protocol
Listeners, the Hostname value must be different on each Listener for the
Listener to be distinct.
When the Listeners are distinct based on Hostname, inbound request
hostnames MUST match from the most specific to least specific Hostname
values to choose the correct Listener and its associated set of Routes.
Exact matches must be processed before wildcard matches, and wildcard
matches must be processed before fallback (empty Hostname value)
matches. For example, `"foo.example.com"` takes precedence over
`"*.example.com"`, and `"*.example.com"` takes precedence over `""`.
Additionally, if there are multiple wildcard entries, more specific
wildcard entries must be processed before less specific wildcard entries.
For example, `"*.foo.example.com"` takes precedence over `"*.example.com"`.
The precise definition here is that the higher the number of dots in the
hostname to the right of the wildcard character, the higher the precedence.
The wildcard character will match any number of characters _and dots_ to
the left, however, so `"*.example.com"` will match both
`"foo.bar.example.com"` _and_ `"bar.example.com"`.
If a set of Listeners contains Listeners that are not distinct, then those
Listeners are Conflicted, and the implementation MUST set the "Conflicted"
condition in the Listener Status to "True".
Implementations MAY choose to accept a Gateway with some Conflicted
Listeners only if they only accept the partial Listener set that contains
no Conflicted Listeners. To put this another way, implementations may
accept a partial Listener set only if they throw out *all* the conflicting
Listeners. No picking one of the conflicting listeners as the winner.
This also means that the Gateway must have at least one non-conflicting
Listener in this case, otherwise it violates the requirement that at
least one Listener must be present.
The implementation MUST set a "ListenersNotValid" condition on the
Gateway Status when the Gateway contains Conflicted Listeners whether or
not they accept the Gateway. That Condition SHOULD clearly
indicate in the Message which Listeners are conflicted, and which are
Accepted. Additionally, the Listener status for those listeners SHOULD
indicate which Listeners are conflicted and not Accepted.
A Gateway's Listeners are considered "compatible" if:
1. They are distinct.
2. The implementation can serve them in compliance with the Addresses
requirement that all Listeners are available on all assigned
addresses.
Compatible combinations in Extended support are expected to vary across
implementations. A combination that is compatible for one implementation
may not be compatible for another.
For example, an implementation that cannot serve both TCP and UDP listeners
on the same address, or cannot mix HTTPS and generic TLS listens on the same port
would not consider those cases compatible, even though they are distinct.
Note that requests SHOULD match at most one Listener. For example, if
Listeners are defined for "foo.example.com" and "*.example.com", a
request to "foo.example.com" SHOULD only be routed using routes attached
to the "foo.example.com" Listener (and not the "*.example.com" Listener).
This concept is known as "Listener Isolation". Implementations that do
not support Listener Isolation MUST clearly document this.
Implementations MAY merge separate Gateways onto a single set of
Addresses if all Listeners across all Gateways are compatible.

AllowedRoutes defines the types of routes that MAY be attached to a

Although a client request may match multiple route rules, only one rule
may ultimately receive the request. Matching precedence MUST be
determined in order of the following criteria:
* The most specific match as defined by the Route type.
* The oldest Route based on creation timestamp. For example, a Route with
a creation timestamp of "2020-09-08 01:02:03" is given precedence over
a Route with a creation timestamp of "2020-09-08 01:02:04".
* If everything else is equivalent, the Route appearing first in
alphabetical order (namespace/name) should be given precedence. For
example, foo/bar is given precedence over foo/baz.
All valid rules within a Route attached to this Listener should be
implemented. Invalid Route rules can be ignored (sometimes that will mean
the full Route). If a Route rule transitions from valid to invalid,
support for that Route rule should be dropped to ensure consistency. For
example, even if a filter specified by a Route rule is invalid, the rest
of the rules within that Route should still be supported.

hostname:
description: |-
Hostname specifies the virtual hostname to match for protocol types that
define this concept. When unspecified, all hostnames are matched. This
field is ignored for protocols that don't require hostname based
matching.
Implementations MUST apply Hostname matching appropriately for each of
the following protocols:
* TLS: The Listener Hostname MUST match the SNI.
* HTTP: The Listener Hostname MUST match the Host header of the request.
* HTTPS: The Listener Hostname SHOULD match at both the TLS and HTTP
protocol layers as described above. If an implementation does not
ensure that both the SNI and Host header match the Listener hostname,
it MUST clearly document that.
For HTTPRoute and TLSRoute resources, there is an interaction with the
`spec.hostnames` array. When both listener and route specify hostnames,
there MUST be an intersection between the values for a Route to be
accepted. For more information, refer to the Route specific Hostnames
documentation.
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`.

available certificates for any TLS handshake.

certificateRefs:
description: |-
CertificateRefs contains a series of references to Kubernetes objects that
contains TLS certificates and private keys. These certificates are used to
establish a TLS handshake for requests that match the hostname of the
associated listener.
A single CertificateRef to a Kubernetes Secret has "Core" support.
Implementations MAY choose to support attaching multiple certificates to
a Listener, but this behavior is implementation-specific.
References to a resource in different namespace are invalid UNLESS there
is a ReferenceGrant in the target namespace that allows the certificate
to be attached. If a ReferenceGrant does not allow this reference, the
"ResolvedRefs" condition MUST be set to False for this listener with the
"RefNotPermitted" reason.
This field is required to have at least one element when the mode is set
to "Terminate" (default) and is optional otherwise.
CertificateRefs can reference to standard Kubernetes resources, i.e.
Secret, or implementation-specific custom resources.

Mode defines the TLS behavior for the TLS session initiated by the client.

to be specified in some way, such as populating the certificateRefs
field.
- Passthrough: The TLS session is NOT terminated by the Gateway. This
implies that the Gateway can't decipher the TLS stream except for
the ClientHello message of the TLS protocol. The certificateRefs field
