Struct HTTPRouteRulesBackendRefs

pub struct HTTPRouteRulesBackendRefs {
    pub filters: Option<Vec<HTTPRouteRulesBackendRefsFilters>>,
    pub group: Option<String>,
    pub kind: Option<String>,
    pub name: String,
    pub namespace: Option<String>,
    pub port: Option<i32>,
    pub weight: Option<i32>,
}

HTTPBackendRef defines how a HTTPRoute forwards a HTTP request.

Note that when a namespace different than the local namespace is specified, a ReferenceGrant object is required in the referent namespace to allow that namespace’s owner to accept the reference. See the ReferenceGrant documentation for details.

gateway:experimental:description

When the BackendRef points to a Kubernetes Service, implementations SHOULD honor the appProtocol field if it is set for the target Service Port.

Implementations supporting appProtocol SHOULD recognize the Kubernetes Standard Application Protocols defined in KEP-3726.

If a Service appProtocol isn’t specified, an implementation MAY infer the backend protocol through its own means. Implementations MAY infer the protocol from the Route type referring to the backend Service.

If a Route is not able to send traffic to the backend using the specified protocol then the backend is considered invalid. Implementations MUST set the “ResolvedRefs” condition to “False” with the “UnsupportedProtocol” reason.

Fields

filters: Option<Vec<HTTPRouteRulesBackendRefsFilters>>

Filters defined at this level should be executed if and only if the request is being forwarded to the backend defined here.

Support: Implementation-specific (For broader support of filters, use the Filters field in HTTPRouteRule.)

group: Option<String>

Group is the group of the referent. For example, “gateway.networking.k8s.io”. When unspecified or empty string, core API group is inferred.

kind: Option<String>

Kind is the Kubernetes resource kind of the referent. For example “Service”.

Defaults to “Service” when not specified.

ExternalName services can refer to CNAME DNS records that may live outside of the cluster and as such are difficult to reason about in terms of conformance. They also may not be safe to forward to (see CVE-2021-25740 for more information). Implementations SHOULD NOT support ExternalName Services.

Support: Core (Services with a type other than ExternalName)

Support: Implementation-specific (Services with type ExternalName)

name: String

Name is the name of the referent.

namespace: Option<String>

Namespace is the namespace of the backend. When unspecified, the local namespace is inferred.

Note that when a namespace different than the local namespace is specified, a ReferenceGrant object is required in the referent namespace to allow that namespace’s owner to accept the reference. See the ReferenceGrant documentation for details.

Support: Core

port: Option<i32>

Port specifies the destination port number to use for this resource. Port is required when the referent is a Kubernetes Service. In this case, the port number is the service port number, not the target port. For other resources, destination port might be derived from the referent resource or this field.

weight: Option<i32>

Weight specifies the proportion of requests forwarded to the referenced backend. This is computed as weight/(sum of all weights in this BackendRefs list). For non-zero values, there may be some epsilon from the exact proportion defined here depending on the precision an implementation supports. Weight is not a percentage and the sum of weights does not need to equal 100.

If only one backend is specified and it has a weight greater than 0, 100% of the traffic is forwarded to that backend. If weight is set to 0, no traffic should be forwarded for this entry. If unspecified, weight defaults to 1.

Support for this field varies based on the context where used.

Trait Implementations

impl Clone for HTTPRouteRulesBackendRefs

fn clone(&self) -> HTTPRouteRulesBackendRefs

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HTTPRouteRulesBackendRefs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HTTPRouteRulesBackendRefs

fn default() -> HTTPRouteRulesBackendRefs

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HTTPRouteRulesBackendRefs

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for HTTPRouteRulesBackendRefs

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for HTTPRouteRulesBackendRefs

fn eq(&self, other: &HTTPRouteRulesBackendRefs) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for HTTPRouteRulesBackendRefs

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
