Overview

Package flowcontrol provides api definitions for the "flowcontrol.apiserver.k8s.io" api group.

	VerbAll        = "*"
	NonResourceAll = "*"
	NameAll        = "*"

Constants used by api validation.

View Source
const GroupName = "flowcontrol.apiserver.k8s.io"

GroupName is the name of api group

Variables

	// AddToScheme adds api to a scheme
	AddToScheme = SchemeBuilder.AddToScheme

Functions

func Kind

func Kind(kind string) schema.GroupKind

Kind takes an unqualified kind and returns a Group qualified GroupKind

func Resource

func Resource(resource string) schema.GroupResource

Resource takes an unqualified resource and returns a Group qualified GroupResource

Types

type ConditionStatus

type ConditionStatus string

ConditionStatus is the status of the condition.

const (
	ConditionTrue    ConditionStatus = "True"
	ConditionFalse   ConditionStatus = "False"
	ConditionUnknown ConditionStatus = "Unknown"
)

These are valid condition statuses. "ConditionTrue" means a resource is in the condition. "ConditionFalse" means a resource is not in the condition. "ConditionUnknown" means kubernetes can't decide if a resource is in the condition or not. In the future, we could add other intermediate conditions, e.g. ConditionDegraded.

type ExemptPriorityLevelConfiguration added in v1.28.0

type ExemptPriorityLevelConfiguration struct {
	// `nominalConcurrencyShares` (NCS) contributes to the computation of the
	// NominalConcurrencyLimit (NominalCL) of this level.
	// This is the number of execution seats nominally reserved for this priority level.
	// This DOES NOT limit the dispatching from this priority level
	// but affects the other priority levels through the borrowing mechanism.
	// The server's concurrency limit (ServerCL) is divided among all the
	// priority levels in proportion to their NCS values:
	//
	// NominalCL(i)  = ceil( ServerCL * NCS(i) / sum_ncs )
	// sum_ncs = sum[priority level k] NCS(k)
	//
	// Bigger numbers mean a larger nominal concurrency limit,
	// at the expense of every other priority level.
	// This field has a default value of zero.
	// +optional
	NominalConcurrencyShares *int32
	// `lendablePercent` prescribes the fraction of the level's NominalCL that
	// can be borrowed by other priority levels.  This value of this
	// field must be between 0 and 100, inclusive, and it defaults to 0.
	// The number of seats that other levels can borrow from this level, known
	// as this level's LendableConcurrencyLimit (LendableCL), is defined as follows.
	//
	// LendableCL(i) = round( NominalCL(i) * lendablePercent(i)/100.0 )
	//
	// +optional

	FlowDistinguisherMethodByUserType FlowDistinguisherMethodType = "ByUser"

	// FlowDistinguisherMethodByNamespaceType specifies that the flow distinguisher is the namespace of the
	// object that the request acts upon. If the object is not namespaced, or if the request is a non-resource
	// request, then the distinguisher will be the empty string. An example usage of this type is to provide
	// some insulation between tenants in a situation where there are multiple tenants and each namespace
	// is dedicated to a tenant.
	FlowDistinguisherMethodByNamespaceType FlowDistinguisherMethodType = "ByNamespace"
)

These are valid flow-distinguisher methods.

type ResourcePolicyRule

type ResourcePolicyRule struct {
	// `verbs` is a list of matching verbs and may not be empty.

	// +listType=set
	// Required.

	// and plural) with, if desired, subresource.  For example, [
	// "services", "nodes/status" ].  This list may not be empty.

	// `clusterScope` indicates whether to match requests that do not
	// specify a namespace (which happens either because the resource

	// matches.  A request that specifies a target namespace matches
	// only if either (a) this list contains that target namespace or

	// specified namespace but does not match a request that _does
	// not specify_ a namespace (see the `clusterScope` field for

ResourcePolicyRule is a predicate that matches some resource requests, testing the request's verb and the target resource. A ResourcePolicyRule matches a resource request if and only if: (a) at least one member of verbs matches the request, (b) at least one member of apiGroups matches the request, (c) at least one member of resources matches the request, and (d) least one member of namespaces matches the request.
