Functions

func Resource 

func Resource(resource string) schema.GroupResource

Resource takes an unqualified resource and returns a Group qualified GroupResource

Types

type AbsoluteURI added in v1.42.0 

type AbsoluteURI string

The AbsoluteURI MUST NOT be a relative URI, and it MUST follow the URI syntax and encoding rules specified in RFC3986. The AbsoluteURI MUST include both a scheme (e.g., "http" or "spiffe") and a scheme-specific-part. URIs that include an authority MUST include a fully qualified domain name or IP address as the host. <gateway:util:excludeFromCRD> The below regex is taken from the regex section in RFC 3986 with a slight modification to enforce a full URI and not relative. </gateway:util:excludeFromCRD> +kubebuilder:validation:MinLength=1 +kubebuilder:validation:MaxLength=253 +kubebuilder:validation:Pattern=`^(([^:/?#]+):)(//([^/?#]*))([^?#]*)(\?([^#]*))?(#(.*))?`

type AddressType 

type AddressType string

AddressType defines how a network address is represented as a text string. This may take two possible forms:

* A predefined CamelCase string identifier (currently limited to `IPAddress` or `Hostname`) * A domain-prefixed string identifier (like `acme.io/CustomAddressType`)

Values `IPAddress` and `Hostname` have Extended support.

The `NamedAddress` value has been deprecated in favor of implementation specific domain-prefixed strings.

All other values, including domain-prefixed values have Implementation-specific support, which are used in implementation-specific behaviors. Support for additional predefined CamelCase identifiers may be added in future releases.

+kubebuilder:validation:MinLength=1 +kubebuilder:validation:MaxLength=253 +kubebuilder:validation:Pattern=`^Hostname|IPAddress|NamedAddress|[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*\/[A-Za-z0-9\/\-._~%!$&'()*+,;=:]+$` 

const (
	// A textual representation of a numeric IP address. IPv4
	// addresses must be in dotted-decimal form. IPv6 addresses
	// must be in a standard IPv6 text representation
	// (see [RFC 5952](https://tools.ietf.org/html/rfc5952)).
	//
	// This type is intended for specific addresses. Address ranges are not

	// IPAddress).
	//
	// Support: Extended
	IPAddressType AddressType = "IPAddress"

	// A Hostname represents a DNS based ingress point. This is similar to the
	// corresponding hostname field in Kubernetes load balancer status. For
	// example, this concept may be used for cloud load balancers where a DNS
	// name is used to expose a load balancer.
	//
	// Support: Extended
	HostnameAddressType AddressType = "Hostname"

	// A NamedAddress provides a way to reference a specific IP address by name.
	// For example, this may be a name or other unique identifier that refers
	// to a resource on a cloud provider such as a static IP.
	//
	// The `NamedAddress` type has been deprecated in favor of implementation
	// specific domain-prefixed strings.
	//
	// Support: Implementation-specific
	NamedAddressType AddressType = "NamedAddress"
)

type AnnotationKey 

type AnnotationKey string

AnnotationKey is the key of an annotation in Gateway API. This is used for validation of maps such as TLS options. This matches the Kubernetes "qualified name" validation that is used for annotations and other common values.

Valid values include:

* example * example.com * example.com/path * example.com/path.html

Invalid values include:

* example~ - "~" is an invalid character * example.com. - cannot start or end with "."

+kubebuilder:validation:MinLength=1 +kubebuilder:validation:MaxLength=253 +kubebuilder:validation:Pattern=`^([a-z0-9]([-a-z0-9]*[a-z0-9])?(\\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*/)?([A-Za-z0-9][-A-Za-z0-9_.]{0,61})?[A-Za-z0-9]$`

type AnnotationValue 

type AnnotationValue string

AnnotationValue is the value of an annotation in Gateway API. This is used for validation of maps such as TLS options. This roughly matches Kubernetes annotation validation, although the length validation in that case is based on the entire size of the annotations struct.

+kubebuilder:validation:MinLength=0 +kubebuilder:validation:MaxLength=4096

type BackendObjectReference

BackendObjectReference defines how an ObjectReference that is specific to BackendRef. It includes a few additional fields and features than a regular ObjectReference.

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.

The API object must be valid in the cluster; the Group and Kind must be registered in the cluster for this reference to be valid.

References to objects with invalid Group and Kind are not valid, and must be rejected by the implementation, with appropriate Conditions set on the containing object.

+kubebuilder:validation:XValidation:message="Must have port for Service reference",rule="(size(self.group) == 0 && self.kind == 'Service') ? has(self.port) : true"

func (*BackendObjectReference) DeepCopy 

func (in *BackendObjectReference) DeepCopy() *BackendObjectReference

func (*BackendObjectReference) DeepCopyInto 

func (in *BackendObjectReference) DeepCopyInto(out *BackendObjectReference)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type BackendRef 

type BackendRef struct {
	// BackendObjectReference references a Kubernetes object.
	BackendObjectReference `json:",inline"`

	// 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.
	//
	// +optional
	// +kubebuilder:default=1
	// +kubebuilder:validation:Minimum=0
	// +kubebuilder:validation:Maximum=1000000
	Weight *int32 `json:"weight,omitempty"`
}

BackendRef defines how a Route should forward a request to a Kubernetes resource.

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.

</gateway:experimental:description>

Note that when the BackendTLSPolicy object is enabled by the implementation, there are some extra rules about validity to consider here. See the fields where this struct is used for more information about the exact behavior.

func (*BackendRef) DeepCopy 

func (in *BackendRef) DeepCopy() *BackendRef

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new BackendRef.

func (*BackendRef) DeepCopyInto 

func (in *BackendRef) DeepCopyInto(out *BackendRef)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type CORSOrigin added in v1.42.0 

type CORSOrigin string

The CORSOrigin MUST NOT be a relative URI, and it MUST follow the URI syntax and encoding rules specified in RFC3986. The CORSOrigin MUST include both a scheme (e.g., "http" or "spiffe") and a scheme-specific-part, or it should be a single '*' character. URIs that include an authority MUST include a fully qualified domain name or IP address as the host. <gateway:util:excludeFromCRD> The below regex was generated to simplify the assertion of scheme://host:<port> being port optional </gateway:util:excludeFromCRD> +kubebuilder:validation:MinLength=1 +kubebuilder:validation:MaxLength=253 +kubebuilder:validation:Pattern=`(^\*$)|(^([a-zA-Z][a-zA-Z0-9+\-.]+):\/\/([^:/?#]+)(:([0-9]{1,5}))?$)`

type CommonRouteSpec 

type CommonRouteSpec struct {
	// ParentRefs references the resources (usually Gateways) that a Route wants
	// to be attached to. Note that the referenced parent resource needs to
	// allow this for the attachment to be complete. For Gateways, that means
	// the Gateway needs to allow attachment from Routes of this kind and
	// namespace. For Services, that means the Service must either be in the same
	// namespace for a "producer" route, or the mesh implementation must support
	// and allow "consumer" routes for the referenced Service. ReferenceGrant is
	// not applicable for governing ParentRefs to Services - it is not possible to
	// create a "producer" route for a Service in a different namespace from the
	// Route.
	//
	// There are two kinds of parent resources with "Core" support:
	//
	// * Gateway (Gateway conformance profile)
	// * Service (Mesh conformance profile, ClusterIP Services only)
	//
	// This API may be extended in the future to support additional kinds of parent
	// resources.
	//
	// ParentRefs must be _distinct_. This means either that:
	//
	// * They select different objects.  If this is the case, then parentRef
	//   entries are distinct. In terms of fields, this means that the
	//   multi-part key defined by `group`, `kind`, `namespace`, and `name` must
	//   be unique across all parentRef entries in the Route.
	// * They do not select different objects, but for each optional field used,
	//   each ParentRef that selects the same object must set the same set of
	//   optional fields to different values. If one ParentRef sets a
	//   combination of optional fields, all must set the same combination.
	//
	// Some examples:
	//
	// * If one ParentRef sets `sectionName`, all ParentRefs referencing the
	//   same object must also set `sectionName`.
	// * If one ParentRef sets `port`, all ParentRefs referencing the same
	//   object must also set `port`.
	// * If one ParentRef sets `sectionName` and `port`, all ParentRefs
	//   referencing the same object must also set `sectionName` and `port`.
	//
	// It is possible to separately reference multiple distinct objects that may
	// be collapsed by an implementation. For example, some implementations may
	// choose to merge compatible Gateway Listeners together. If that is the
	// case, the list of routes attached to those resources should also be
	// merged.
	//
	// Note that for ParentRefs that cross namespace boundaries, there are specific
	// rules. 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 other kinds 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.

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.

HTTPHeaderFilter defines a filter that modifies the headers of an HTTP request or response. Only one action for a given header name is permitted. Filters specifying multiple actions of the same or different type for any one header name are invalid. Configuration to set or add multiple values for a header must use RFC 7230 header value formatting, separating each value with a comma.

type RouteStatus 

type RouteStatus struct {
	// Parents is a list of parent resources (usually Gateways) that are
	// associated with the route, and the status of the route with respect to
	// each parent. When this route attaches to a parent, the controller that
	// manages the parent must add an entry to this list when the controller
	// first sees the route and should update the entry as appropriate when the
	// route or gateway is modified.
	//
	// Note that parent references that cannot be resolved by an implementation
	// of this API will not be added to this list. Implementations of this API
	// can only populate Route status for the Gateways/parent resources they are

	//
	// A maximum of 32 Gateways will be represented in this list. An empty list

type SectionName 

type SectionName string

SectionName is the name of a section in a Kubernetes resource.

In the following resources, SectionName is interpreted as the following:
