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

var (
	// SchemeBuilder installs the api group to a scheme

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

var SchemeGroupVersion = schema.GroupVersion{Group: GroupName, Version: runtime.APIVersionInternal}

SchemeGroupVersion is group version used to register these objects

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
	LendablePercent *int32
}

ExemptPriorityLevelConfiguration describes the configurable aspects of the handling of exempt requests. In the mandatory exempt configuration object the values in the fields here can be modified by authorized users, unlike the rest of the `spec`.

type QueuingConfiguration 

type QueuingConfiguration struct {
	// `queues` is the number of queues for this priority level. The
	// queues exist independently at each apiserver. The value must be
	// positive.  Setting it to 1 effectively precludes
	// shufflesharding and thus makes the distinguisher method of
	// associated flow schemas irrelevant.  This field has a default
	// value of 64.
	// +optional
	Queues int32

	// `handSize` is a small positive number that configures the
	// shuffle sharding of requests into queues.  When enqueuing a request
	// at this priority level the request's flow identifier (a string
	// pair) is hashed and the hash value is used to shuffle the list
	// of queues and deal a hand of the size specified here.  The
	// request is put into one of the shortest queues in that hand.
	// `handSize` must be no larger than `queues`, and should be
	// significantly smaller (so that a few heavy flows do not
	// saturate most of the queues).  See the user-facing
	// documentation for more extensive guidance on setting this
	// field.  This field has a default value of 8.
	// +optional
	HandSize int32

	// `queueLengthLimit` is the maximum number of requests allowed to
	// be waiting in a given queue of this priority level at a time;
	// excess requests are rejected.  This value must be positive.  If
	// not specified, it will be defaulted to 50.
	// +optional
	QueueLengthLimit int32
}

QueuingConfiguration holds the configuration parameters for queuing

func (*QueuingConfiguration) DeepCopy 

func (in *QueuingConfiguration) DeepCopy() *QueuingConfiguration

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

func (*QueuingConfiguration) DeepCopyInto 

func (in *QueuingConfiguration) DeepCopyInto(out *QueuingConfiguration)

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

type ResourcePolicyRule 

type ResourcePolicyRule struct {
	// `verbs` is a list of matching verbs and may not be empty.
	// "*" matches all verbs and, if present, must be the only entry.
	// +listType=set
	// Required.
	Verbs []string

	// `apiGroups` is a list of matching API groups and may not be empty.
	// "*" matches all API groups and, if present, must be the only entry.
	// +listType=set
	// Required.
	APIGroups []string

	// `resources` is a list of matching resources (i.e., lowercase
	// and plural) with, if desired, subresource.  For example, [
	// "services", "nodes/status" ].  This list may not be empty.
	// "*" matches all resources and, if present, must be the only entry.
	// Required.
	// +listType=set
	Resources []string

	// `clusterScope` indicates whether to match requests that do not
	// specify a namespace (which happens either because the resource
	// is not namespaced or the request targets all namespaces).
	// If this field is omitted or false then the `namespaces` field
	// must contain a non-empty list.
	// +optional
	ClusterScope bool

	// `namespaces` is a list of target namespaces that restricts
	// matches.  A request that specifies a target namespace matches
	// only if either (a) this list contains that target namespace or
	// (b) this list contains "*".  Note that "*" matches any
	// specified namespace but does not match a request that _does
	// not specify_ a namespace (see the `clusterScope` field for
	// that).
	// This list may be empty, but only if `clusterScope` is true.
	// +optional
	// +listType=set
	Namespaces []string
}

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.

func (*ResourcePolicyRule) DeepCopy 

func (in *ResourcePolicyRule) DeepCopy() *ResourcePolicyRule

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

func (*ResourcePolicyRule) DeepCopyInto 

func (in *ResourcePolicyRule) DeepCopyInto(out *ResourcePolicyRule)

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

type ServiceAccountSubject 

type ServiceAccountSubject struct {
	// `namespace` is the namespace of matching ServiceAccount objects.
	// Required.
	Namespace string
	// `name` is the name of matching ServiceAccount objects, or "*" to match regardless of name.
	// Required.
	Name string
}

type Subject 

type Subject struct {
	// `kind` indicates which one of the other fields is non-empty.
	// Required
	// +unionDiscriminator
	Kind SubjectKind
	// `user` matches based on username.
	// +optional
	User *UserSubject
	// `group` matches based on user group name.
	// +optional
	Group *GroupSubject
	// `serviceAccount` matches ServiceAccounts.
	// +optional
	ServiceAccount *ServiceAccountSubject
}

Subject matches the originator of a request, as identified by the request authentication system. There are three ways of matching an originator; by user, group, or service account. +union
