ClientCIDRs are the IP CIDR ranges of the client. Valid examples are "192.168.1.0/24" or "2001:db8::/64" If multiple CIDR ranges are specified, one of the CIDR ranges must match the client IP for the rule to match. The client IP is inferred from the X-Forwarded-For header, a custom header, or the proxy protocol. You can use the `ClientIPDetection` or the `ProxyProtocol` field in the `ClientTrafficPolicy` to configure how the client IP is detected. For TCPRoute targets (raw TCP connections), HTTP headers such as X-Forwarded-For are not available. The client IP is obtained from the TCP connection's peer address. If intermediaries (load balancers, NAT) terminate or proxy TCP, the original client IP will only be available if the intermediary preserves the source address (for example by enabling the PROXY protocol or avoiding SNAT). Ensure your L4 proxy is configured to preserve the source IP to enable correct client-IP matching for TCPRoute targets.

FailOpen is a switch used to control the behavior when a response from the External Authorization service cannot be obtained. If FailOpen is set to true, the system allows the traffic to pass through. Otherwise, if it is set to false or not set (defaulting to false), the system blocks the traffic and returns a HTTP 5xx error, reflecting a fail-closed approach. This setting determines whether to prioritize accessibility over strict security in case of authorization service failure. If set to true, the External Authorization will also be bypassed if its configuration is invalid.

matchExpressions []object
MatchExpressions is a list of label selector requirements. The requirements are ANDed.
key string required
key is the label key that the selector applies to.
operator string required
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
values []string
values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.
matchLabels object
MatchLabels are the set of label selectors for identifying the targeted resource.
namespaces object
Namespaces determines which namespaces are considered for target selection. If unspecified, only targets in the same namespace as this policy are considered. When specified, the effective set of namespaces is always constrained to the namespaces watched by Envoy Gateway. Selecting targets across namespaces requires a ReferenceGrant in the target namespace that allows this policy kind to reference the selected target kind. Cross-namespace targets without a matching ReferenceGrant are ignored.
from string required
From indicates how namespaces are selected for this target selector. All means all namespaces watched by Envoy Gateway. Selector means namespaces watched by Envoy Gateway that match Selector.
enum: Same, All, Selector
selector object
Selector selects namespaces when From is set to Selector.
matchExpressions []object
matchExpressions is a list of label selector requirements. The requirements are ANDed.
key string required
key is the label key that the selector applies to.
operator string required
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
values []string
values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.
matchLabels object
matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed.
status object
Status defines the current status of SecurityPolicy.
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.
group string
Group is the group of the referent. When unspecified, "gateway.networking.k8s.io" is inferred. To set the core API group (such as for a "Service" kind referent), Group must be explicitly set to "" (empty string). Support: Core

maxLength: 253
kind string
Kind is kind of the referent. There are two kinds of parent resources with "Core" support: * Gateway (Gateway conformance profile) * Service (Mesh conformance profile, ClusterIP Services only) Support for other resources is Implementation-Specific.
pattern: ^[a-zA-Z]([-a-zA-Z0-9]*[a-zA-Z0-9])?$

name string required
Name is the name of the referent. Support: Core
minLength: 1
maxLength: 253
namespace string
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

maximum: 65535
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

maxLength: 253
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>

lastTransitionTime string required
lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.
format: date-time
message string required
message is a human readable message indicating details about the transition. This may be an empty string.
maxLength: 32768
observedGeneration integer
observedGeneration represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date with respect to the current state of the instance.
format: int64
minimum: 0
reason string required
reason contains a programmatic identifier indicating the reason for the condition's last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.

controllerName string required
ControllerName is a domain/path string that indicates the name of the controller that wrote this status. This corresponds with the controllerName field on GatewayClass. Example: "example.net/gateway-controller". The format of this field is DOMAIN "/" PATH, where DOMAIN and PATH are valid Kubernetes names (https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names). Controllers MUST populate this field when writing status. Controllers should ensure that entries to status populated with their ControllerName are cleaned up when they are no longer necessary.
