View raw schema
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
metadata object
spec object required
Spec defines the desired state of ClientTrafficPolicy.
clientIPDetection object
ClientIPDetectionSettings provides configuration for determining the original client IP address for requests.
customHeader object
CustomHeader provides configuration for determining the client IP address for a request based on a trusted custom HTTP header. This uses the custom_header original IP detection extension. Refer to https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/http/original_ip_detection/custom_header/v3/custom_header.proto for more details.
failClosed boolean
FailClosed is a switch used to control the flow of traffic when client IP detection fails. If set to true, the listener will respond with 403 Forbidden when the client IP address cannot be determined.
name string required
Name of the header containing the original downstream remote address, if present.
pattern: ^[A-Za-z0-9-]+$
minLength: 1
maxLength: 255
xForwardedFor object
XForwardedForSettings provides configuration for using X-Forwarded-For headers for determining the client IP address.
numTrustedHops integer
NumTrustedHops specifies how many trusted hops to count from the rightmost side of the X-Forwarded-For (XFF) header when determining the original client’s IP address. If NumTrustedHops is set to N, the client IP is taken from the Nth address from the right end of the XFF header. Example: XFF = "203.0.113.128, 203.0.113.10, 203.0.113.1" NumTrustedHops = 2 → Trusted client address = 203.0.113.10 Only one of NumTrustedHops or TrustedCIDRs should be configured.
format: int32
trustedCIDRs []string
TrustedCIDRs is a list of CIDR ranges to trust when evaluating the remote IP address to determine the original client’s IP address. When the remote IP address matches a trusted CIDR and the x-forwarded-for header was sent, each entry in the x-forwarded-for header is evaluated from right to left and the first public non-trusted address is used as the original client address. If all addresses in x-forwarded-for are within the trusted list, the first (leftmost) entry is used. Only one of NumTrustedHops and TrustedCIDRs must be set.
minItems: 1
connection object
Connection includes client connection settings.

pattern: ^([0-9]{1,5}(h|m|s|ms)){1,4}$
maxRequestsPerConnection integer
MaxRequestsPerConnection defines the maximum number of requests allowed over a single connection. If not specified, there is no limit. Setting this parameter to 1 will effectively disable keep alive.
format: int32
maxStreamDuration string
MaxStreamDuration is the maximum amount of time to keep alive an http stream. When the limit is reached the stream will be reset independent of any other timeouts. If not specified, no value is set.

preserveXRequestID boolean
PreserveXRequestID configures Envoy to keep the X-Request-ID header if passed for a request that is edge (Edge request is the request from external clients to front Envoy) and not reset it, which is the current Envoy behaviour. Defaults to false and cannot be combined with RequestID. Deprecated: use RequestID=PreserveOrGenerate instead
requestID string
RequestID configures Envoy's behavior for handling the `X-Request-ID` header. When omitted default behavior is `Generate` which builds the `X-Request-ID` for every request and ignores pre-existing values from the edge. (An "edge request" refers to a request from an external client to the Envoy entrypoint.)
enum: PreserveOrGenerate, Preserve, Generate, Disable

enum: Allow, RejectRequest, DropHeader
xForwardedClientCert object
XForwardedClientCert configures how Envoy Proxy handle the x-forwarded-client-cert (XFCC) HTTP header. x-forwarded-client-cert (XFCC) is an HTTP header used to forward the certificate information of part or all of the clients or proxies that a request has flowed through, on its way from the client to the server. Envoy proxy may choose to sanitize/append/forward the XFCC header before proxying the request. If not set, the default behavior is sanitizing the XFCC header.
certDetailsToAdd []string
CertDetailsToAdd specifies the fields in the client certificate to be forwarded in the XFCC header. Hash(the SHA 256 digest of the current client certificate) and By(the Subject Alternative Name) are always included if the client certificate is forwarded. This field is only applicable when the mode is set to `AppendForward` or `SanitizeSet` and the client connection is mTLS.

disableSafeMaxConnectionDuration boolean
DisableSafeMaxConnectionDuration controls the close behavior for HTTP/1 connections. By default, connection closure is delayed until the next request arrives after maxConnectionDuration is exceeded. It then adds a Connection: close header and gracefully closes the connection after the response completes. When set to true (disabled), Envoy uses its default drain behavior, closing the connection shortly after maxConnectionDuration elapses. Has no effect unless maxConnectionDuration is set.
enableTrailers boolean
EnableTrailers defines if HTTP/1 trailers should be proxied by Envoy.
http10 object
HTTP10 turns on support for HTTP/1.0 and HTTP/0.9 requests.
useDefaultHost boolean
UseDefaultHost specifies whether a default Host header should be injected into HTTP/1.0 requests that do not include one. When set to true, Envoy Gateway injects the hostname associated with the listener or route into the request, in the following order: 1. If the targeted listener has a non-wildcard hostname, use that hostname. 2. If there is exactly one HTTPRoute with a non-wildcard hostname under the targeted listener, use that hostname. Note: Setting this field to true without a non-wildcard hostname makes the ClientTrafficPolicy invalid.
preserveHeaderCase boolean
PreserveHeaderCase defines if Envoy should preserve the letter case of headers. By default, Envoy will lowercase all the headers.
http2 object
HTTP2 provides HTTP/2 configuration on the listener.
initialConnectionWindowSize string | integer
InitialConnectionWindowSize sets the initial window size for HTTP/2 connections. If not set, the default value is 1 MiB.
initialStreamWindowSize string | integer
InitialStreamWindowSize sets the initial window size for HTTP/2 streams. If not set, the default value is 64 KiB(64*1024).
maxConcurrentStreams integer
MaxConcurrentStreams sets the maximum number of concurrent streams allowed per connection. If not set, the default value is 100.
format: int32
minimum: 1
maximum: 2.147483647e+09

http3 object
HTTP3 provides HTTP/3 configuration on the listener.
path object

EscapedSlashesAction determines how %2f, %2F, %5c, or %5C sequences in the path URI should be handled. The default is UnescapeAndRedirect.
enum: KeepUnchanged, RejectRequest, UnescapeAndForward, UnescapeAndRedirect
proxyProtocol object
ProxyProtocol configures the Proxy Protocol settings. When configured, the Proxy Protocol header will be interpreted and the Client Address will be added into the X-Forwarded-For header. If both EnableProxyProtocol and ProxyProtocol are set, ProxyProtocol takes precedence.
optional boolean
Optional allows requests without a Proxy Protocol header to be proxied. If set to true, the listener will accept requests without a Proxy Protocol header. If set to false, the listener will reject requests without a Proxy Protocol header. If not set, the default behavior is to reject requests without a Proxy Protocol header. Warning: Optional breaks conformance with the specification. Only enable if ALL traffic to the listener comes from a trusted source. For more information on security implications, see haproxy.org/download/2.1/doc/proxy-protocol.txt
scheme string
Scheme configures how the :scheme pseudo-header is set for requests forwarded to backends. - Preserve (default): Preserves the :scheme from the original client request. Use this when backends need to know the original client scheme for URL generation or redirects. - MatchBackend: Sets the :scheme to match the backend transport protocol. If the backend uses TLS, the scheme is "https", otherwise "http". Use this when backends require the scheme to match the actual transport protocol, such as strictly HTTPS services that validate the :scheme header.

ECDHCurves specifies the set of supported ECDH curves. In non-FIPS Envoy Proxy builds the default curves are: - X25519 - P-256 In builds using BoringSSL FIPS the default curve is: - P-256
maxVersion string
Max specifies the maximal TLS protocol version to allow The default is TLS 1.3 if this is not specified.
enum: Auto, 1.0, 1.1, 1.2, 1.3
minVersion string
Min specifies the minimal TLS protocol version to allow. The default is TLS 1.2 if this is not specified.
enum: Auto, 1.0, 1.1, 1.2, 1.3
session object
Session defines settings related to TLS session management.
resumption object
Resumption determines the proxy's supported TLS session resumption option. By default, Envoy Gateway does not enable session resumption. Use sessionResumption to enable stateful and stateless session resumption. Users should consider security impacts of different resumption methods. Performance gains from resumption are diminished when Envoy proxy is deployed with more than one replica.
stateful object
Stateful defines setting for stateful (session-id based) session resumption
stateless object
Stateless defines setting for stateless (session-ticket based) session resumption
signatureAlgorithms []string
SignatureAlgorithms specifies which signature algorithms the listener should support.
status object
Status defines the current status of ClientTrafficPolicy.
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

name string required
Name is the name of the referent. Support: Core

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

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>

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.
