namespace string required
Namespace is the namespace of the dynamic metadata.
number integer
Number specifies the fixed usage number to reduce the rate limit counters. Using zero can be used to only check the rate limit counters without reducing them.
format: int64
limit object required
Limit holds the rate limit values. This limit is applied for traffic flows when the selectors compute to True, causing the request to be counted towards the limit. The limit is enforced and the request is ratelimited, i.e. a response with 429 HTTP status code is sent back to the client when the selected requests have reached the limit.
requests integer required
unit string required
RateLimitUnit specifies the intervals for setting rate limits. Valid RateLimitUnit values are "Second", "Minute", "Hour", "Day", "Month" and "Year".
enum: Second, Minute, Hour, Day, Month, Year
shadowMode boolean
ShadowMode indicates whether this rate-limit rule runs in shadow mode. When enabled, all rate-limiting operations are performed (cache lookups, counter updates, telemetry generation), but the outcome is never enforced. The request always succeeds, even if the configured limit is exceeded. Only supported for Global Rate Limits.
shared boolean
Shared determines whether this rate limit rule applies across all the policy targets. If set to true, the rule is treated as a common bucket and is shared across all policy targets (xRoutes). Default: false.
type string
Type decides the scope for the RateLimits. Valid RateLimitType values are "Global" or "Local". Deprecated: Use Global and/or Local fields directly instead. Both can be specified simultaneously for combined rate limiting.
enum: Global, Local
requestBuffer object
RequestBuffer allows the gateway to buffer and fully receive each request from a client before continuing to send the request upstream to the backends. This can be helpful to shield your backend servers from slow clients, and also to enforce a maximum size per request as any requests larger than the buffer size will be rejected. This can have a negative performance impact so should only be enabled when necessary. When enabling this option, you should also configure your connection buffer size to account for these request buffers. There will also be an increase in memory usage for Envoy that should be accounted for in your deployment settings.
limit string | integer
Limit specifies the maximum allowed size in bytes for each incoming request buffer. If exceeded, the request will be rejected with HTTP 413 Content Too Large. Accepts values in resource.Quantity format (e.g., "10Mi", "500Ki").
responseOverride []object
ResponseOverride defines the configuration to override specific responses with a custom one. If multiple configurations are specified, the first one to match wins.
match object required
Match configuration.
statusCodes []object required
Status code to match on. The match evaluates to true if any of the matches are successful.
minItems: 1
maxItems: 50
range object
Range contains the range of status codes.
end integer required
End of the range, including the end value.

maxLength: 253
path object
Path defines parameters used to modify the path of the incoming request. The modified path is then used to construct the `Location` header. When empty, the request path is used as-is. Only ReplaceFullPath path modifier is supported currently.
replaceFullPath string
ReplaceFullPath specifies the value with which to replace the full path of a request during a rewrite or redirect.
maxLength: 1024
replacePrefixMatch string
ReplacePrefixMatch specifies the value with which to replace the prefix match of a request during a rewrite or redirect. For example, a request to "/foo/bar" with a prefix match of "/foo" and a ReplacePrefixMatch of "/xyz" would be modified to "/xyz/bar". Note that this matches the behavior of the PathPrefix match type. This matches full path elements. A path element refers to the list of labels in the path split by the `/` separator. When specified, a trailing `/` is ignored. For example, the paths `/abc`, `/abc/`, and `/abc/def` would all match the prefix `/abc`, but the path `/abcd` would not. ReplacePrefixMatch is only compatible with a `PathPrefix` HTTPRouteMatch. Using any other HTTPRouteMatch type on the same HTTPRouteRule will result in the implementation setting the Accepted Condition for the Route to `status: False`. Request Path | Prefix Match | Replace Prefix | Modified Path
maxLength: 1024
type string required
Type defines the type of path modifier. Additional types may be added in a future release of the API. Note that values may be added to this enum, implementations must ensure that unknown values will not cause a crash.

enum: ReplaceFullPath, ReplacePrefixMatch
port integer
Port is the port to be used in the value of the `Location` header in the response. If redirect scheme is not-empty, the well-known port associated with the redirect scheme will be used. Specifically "http" to port 80 and "https" to port 443. If the redirect scheme does not have a well-known port or redirect scheme is empty, the listener port of the Gateway will be used. Port will not be added in the 'Location' header if scheme is HTTP and port is 80 or scheme is HTTPS and port is 443.
format: int32

ancestors []object required
Ancestors is a list of ancestor resources (usually Gateways) that are associated with the policy, and the status of the policy with respect to each ancestor. When this policy attaches to a parent, the controller that manages the parent and the ancestors MUST add an entry to this list when the controller first sees the policy and SHOULD update the entry as appropriate when the relevant ancestor is modified. Note that choosing the relevant ancestor is left to the Policy designers; an important part of Policy design is designing the right object level at which to namespace this status. Note also that implementations MUST ONLY populate ancestor status for the Ancestor resources they are responsible for. Implementations MUST use the ControllerName field to uniquely identify the entries in this list that they are responsible for. Note that to achieve this, the list of PolicyAncestorStatus structs MUST be treated as a map with a composite key, made up of the AncestorRef and ControllerName fields combined. A maximum of 16 ancestors will be represented in this list. An empty list means the Policy is not relevant for any ancestors. If this slice is full, implementations MUST NOT add further entries. Instead they MUST consider the policy unimplementable and signal that on any related resources such as the ancestor that would be referenced here. For example, if this list was full on BackendTLSPolicy, no additional Gateways would be able to reference the Service targeted by the BackendTLSPolicy.
maxItems: 16
ancestorRef object required
AncestorRef corresponds with a ParentRef in the spec that this PolicyAncestorStatus struct describes the status of.

Namespace is the namespace of the referent. When unspecified, this refers to the local namespace of the Route. Note that there are specific rules for ParentRefs which cross namespace boundaries. 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. <gateway:experimental:description> 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. 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. </gateway:experimental:description> Support: Core

port integer
Port is the network port this Route targets. It can be interpreted differently based on the type of parent resource. 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. <gateway:experimental:description> When the parent resource is a Service, this targets a specific port in the Service spec. When both Port (experimental) and SectionName are specified, the name and port of the selected port must match both specified values. </gateway:experimental:description> Implementations MAY choose to support other parent resources. Implementations supporting other types of parent resources MUST clearly document how/if Port is interpreted. 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. Support: Extended

sectionName string
SectionName is the name of a section within the target resource. In the following resources, SectionName is interpreted as the following: * Gateway: Listener name. When both Port (experimental) and SectionName are specified, the name and port of the selected listener must match both specified values. * Service: Port name. When both Port (experimental) and SectionName are specified, the name and port of the selected listener must match both specified values. Implementations MAY choose to support attaching Routes to other resources. If that is the case, they MUST clearly document how SectionName is interpreted. 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 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. Support: Core

conditions []object required
Conditions describes the status of the Policy with respect to the given Ancestor. <gateway:util:excludeFromCRD> Notes for implementors: Conditions are a listType `map`, which means that they function like a map with a key of the `type` field _in the k8s apiserver_. This means that implementations must obey some rules when updating this section. * Implementations MUST perform a read-modify-write cycle on this field before modifying it. That is, when modifying this field, implementations must be confident they have fetched the most recent version of this field, and ensure that changes they make are on that recent version. * Implementations MUST NOT remove or reorder Conditions that they are not directly responsible for. For example, if an implementation sees a Condition with type `special.io/SomeField`, it MUST NOT remove, change or update that Condition. * Implementations MUST always _merge_ changes into Conditions of the same Type, rather than creating more than one Condition of the same Type. * Implementations MUST always update the `observedGeneration` field of the Condition to the `metadata.generation` of the Gateway at the time of update creation. * If the `observedGeneration` of a Condition is _greater than_ the value the implementation knows about, then it MUST NOT perform the update on that Condition, but must wait for a future reconciliation and status update. (The assumption is that the implementation's copy of the object is stale and an update will be re-triggered if relevant.) </gateway:util:excludeFromCRD>
