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 v1.2.0
type AbsoluteURI string
+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 // supported (e.g. you can not use a CIDR range like 127.0.0.0/24 as an // 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 AllowedRoutes ¶
type AllowedRoutes struct { // Namespaces indicates namespaces from which Routes may be attached to this // Listener. This is restricted to the namespace of this Gateway by default. // // Support: Core // // +optional // +kubebuilder:default={from: Same} Namespaces *RouteNamespaces `json:"namespaces,omitempty"` // Kinds specifies the groups and kinds of Routes that are allowed to bind // to this Gateway Listener. When unspecified or empty, the kinds of Routes // selected are determined using the Listener protocol. // // A RouteGroupKind MUST correspond to kinds of Routes that are compatible // with the application protocol specified in the Listener's Protocol field. // If an implementation does not support or recognize this resource type, it // MUST set the "ResolvedRefs" condition to False for this Listener with the // "InvalidRouteKinds" reason. // // Support: Core // // +optional // +kubebuilder:validation:MaxItems=8 Kinds []RouteGroupKind `json:"kinds,omitempty"` }
AllowedRoutes defines which Routes may be attached to this Listener.
func (*AllowedRoutes) DeepCopy ¶
func (in *AllowedRoutes) DeepCopy() *AllowedRoutes
DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new AllowedRoutes.
func (*AllowedRoutes) DeepCopyInto ¶
func (in *AllowedRoutes) DeepCopyInto(out *AllowedRoutes)
DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.
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. - can not 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 ¶
type BackendObjectReference struct { // Group is the group of the referent. For example, "gateway.networking.k8s.io". // When unspecified or empty string, core API group is inferred. // // +optional // +kubebuilder:default="" Group *Group `json:"group,omitempty"` // 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) // // +optional // +kubebuilder:default=Service Kind *Kind `json:"kind,omitempty"` // Name is the name of the referent. Name ObjectName `json:"name"` // 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 // // +optional Namespace *Namespace `json:"namespace,omitempty"` // 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. // // +optional Port *PortNumber `json:"port,omitempty"` }
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
DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new 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.

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.

GRPCRoute provides a way to route gRPC requests. This includes the capability to match requests by hostname, gRPC service, gRPC method, or HTTP/2 header. Filters can be used to specify additional processing steps. Backends specify where matching requests will be routed.
GRPCRoute falls under extended support within the Gateway API. Within the following specification, the word "MUST" indicates that an implementation supporting GRPCRoute must conform to the indicated requirement, but an implementation not supporting this route type need not follow the requirement unless explicitly indicated.
Implementations supporting `GRPCRoute` with the `HTTPS` `ProtocolType` MUST accept HTTP/2 connections without an initial upgrade from HTTP/1.1, i.e. via ALPN. If the implementation does not support this, then it MUST set the "Accepted" condition to "False" for the affected listener with a reason of "UnsupportedProtocol". Implementations MAY also accept HTTP/2 connections with an upgrade from HTTP/1.
Implementations supporting `GRPCRoute` with the `HTTP` `ProtocolType` MUST support HTTP/2 over cleartext TCP (h2c, https://www.rfc-editor.org/rfc/rfc7540#section-3.1) without an initial upgrade from HTTP/1.1, i.e. with prior knowledge (https://www.rfc-editor.org/rfc/rfc7540#section-3.4).

GRPCRouteMatch defines the predicate used to match requests to a given action. Multiple match types are ANDed together, i.e. the match will evaluate to true only if all conditions are satisfied.
For example, the match below will match a gRPC request only if its service is `foo` AND it contains the `version: v1` header:
``` matches:
- method: type: Exact service: "foo" headers:
- name: "version" value "v1"

GatewayClass describes a class of Gateways available to the user for creating Gateway resources.
It is recommended that this resource be used as a template for Gateways. This means that a Gateway is based on the state of the GatewayClass at the time it was created and changes to the GatewayClass or associated parameters are not propagated down to existing Gateways. This recommendation is intended to limit the blast radius of changes to GatewayClass or associated parameters. If implementations choose to propagate GatewayClass changes to existing Gateways, that MUST be clearly documented by the implementation.
Whenever one or more Gateways are using a GatewayClass, implementations SHOULD add the `gateway-exists-finalizer.gateway.networking.k8s.io` finalizer on the associated GatewayClass. This ensures that a GatewayClass associated with a Gateway is not deleted while in use.

Hostname is particularly relevant // for HTTP or HTTPS protocols. // // When using the Hostname value to select between same-Port, same-Protocol // Listeners, the Hostname value must be different on each Listener for the // Listener to be distinct. // // When the Listeners are distinct based on Hostname, inbound request // hostnames MUST match from the most specific to least specific Hostname // values to choose the correct Listener and its associated set of Routes. // // Exact matches must be processed before wildcard matches, and wildcard // matches must be processed before fallback (empty Hostname value) // matches. For example, `"foo.example.com"` takes precedence over // `"*.example.com"`, and `"*.example.com"` takes precedence over `""`. // // Additionally, if there are multiple wildcard entries, more specific // wildcard entries must be processed before less specific wildcard entries. // For example, `"*.foo.example.com"` takes precedence over `"*.example.com"`. // The precise definition here is that the higher the number of dots in the // hostname to the right of the wildcard character, the higher the precedence. // // The wildcard character will match any number of characters _and dots_ to // the left, however, so `"*.example.com"` will match both // `"foo.bar.example.com"` _and_ `"bar.example.com"`. // // If a set of Listeners contains Listeners that are not distinct, then those // Listeners are Conflicted, and the implementation MUST set the "Conflicted" // condition in the Listener Status to "True". // // Implementations MAY choose to accept a Gateway with some Conflicted // Listeners only if they only accept the partial Listener set that contains // no Conflicted Listeners. To put this another way, implementations may // accept a partial Listener set only if they throw out *all* the conflicting // Listeners. No picking one of the conflicting listeners as the winner. // This also means that the Gateway must have at least one non-conflicting // Listener in this case, otherwise it violates the requirement that at // least one Listener must be present. // // The implementation MUST set a "ListenersNotValid" condition on the // Gateway Status when the Gateway contains Conflicted Listeners whether or // not they accept the Gateway. That Condition SHOULD clearly // indicate in the Message which Listeners are conflicted, and which are // Accepted. Additionally, the Listener status for those listeners SHOULD // indicate which Listeners are conflicted and not Accepted. // // A Gateway's Listeners are considered "compatible" if: // // 1. They are distinct. // 2. The implementation can serve them in compliance with the Addresses // requirement that all Listeners are available on all assigned // addresses. // // Compatible combinations in Extended support are expected to vary across // implementations. A combination that is compatible for one implementation // may not be compatible for another. // // For example, an implementation that cannot serve both TCP and UDP listeners // on the same address, or cannot mix HTTPS and generic TLS listens on the same port // would not consider those cases compatible, even though they are distinct. // // Note that requests SHOULD match at most one Listener. For example, if // Listeners are defined for "foo.example.com" and "*.example.com", a // request to "foo.example.com" SHOULD only be routed using routes attached // to the "foo.example.com" Listener (and not the "*.example.com" Listener). // This concept is known as "Listener Isolation".

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.

PathPrefix and Exact paths must be syntactically valid:
- Must begin with the `/` character - Must not contain consecutive `/` characters (e.g. `/foo///`, `//`).
Note that values may be added to this enum, implementations must ensure that unknown values will not cause a crash.
Unknown values here must result in the implementation setting the Accepted Condition for the Route to `status: False`, with a Reason of `UnsupportedValue`.
+kubebuilder:validation:Enum=Exact;PathPrefix;RegularExpression
const ( // Matches the URL path exactly and with case sensitivity. This means that // an exact path match on `/abc` will only match requests to `/abc`, NOT // `/abc/`, `/Abc`, or `/abcd`. PathMatchExact PathMatchType = "Exact" // Matches based on a URL path prefix split by `/`. Matching is // case sensitive and done on a path element by element basis. 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. // // "PathPrefix" is semantically equivalent to the "Prefix" path type in the // Kubernetes Ingress API.

Core ProtocolType values are listed in the table below.
Implementations can define their own protocols if a core ProtocolType does not exist. Such definitions must use prefixed name, such as `mycompany.com/my-custom-protocol`. Un-prefixed names are reserved for core protocols. Any protocol defined by implementations will fall under Implementation-specific conformance.
Valid values include:
* "HTTP" - Core support * "example.com/bar" - Implementation-specific support
Invalid values include:
* "example.com" - must include path if domain is used * "foo.example.com" - must include path if domain is used

The message // for this condition MUST start with the prefix "Dropped Rule" and // include information about which Rules have been dropped. In this // state, the "Accepted" condition MUST be set to "True" with the latest // generation of the resource. // 2) Fall Back: With this approach, implementations will fall back to the // last known good state of the entire Route. The message for this // condition MUST start with the prefix "Fall Back" and include // information about why the current Rule(s) are invalid. To represent // this, the "Accepted" condition MUST be set to "True" with the // generation of the last known good state of the resource. // // Reverting to the last known good state should only be done by // implementations that have a means of restoring that state if/when they // are restarted. // // This condition MUST NOT be set if a Route is fully valid, fully invalid, // or not accepted. By extension, that means that this condition MUST only // be set when it is "True". // // Possible reasons for this condition to be True are: // // * "UnsupportedValue" // // Controllers may raise this condition with other reasons, but should // prefer to use the reasons listed above to improve interoperability. RouteConditionPartiallyInvalid RouteConditionType = "PartiallyInvalid" )
