Functions

func Convert_eventratelimit_Configuration_To_v1alpha1_Configuration

func Convert_eventratelimit_Configuration_To_v1alpha1_Configuration(in *eventratelimit.Configuration, out *Configuration, s conversion.Scope) error

Convert_eventratelimit_Configuration_To_v1alpha1_Configuration is an autogenerated conversion function.

func Convert_eventratelimit_Limit_To_v1alpha1_Limit

func Convert_eventratelimit_Limit_To_v1alpha1_Limit(in *eventratelimit.Limit, out *Limit, s conversion.Scope) error

Convert_eventratelimit_Limit_To_v1alpha1_Limit is an autogenerated conversion function.

func Convert_v1alpha1_Configuration_To_eventratelimit_Configuration

func Convert_v1alpha1_Configuration_To_eventratelimit_Configuration(in *Configuration, out *eventratelimit.Configuration, s conversion.Scope) error

Convert_v1alpha1_Configuration_To_eventratelimit_Configuration is an autogenerated conversion function.

func Convert_v1alpha1_Limit_To_eventratelimit_Limit

func Convert_v1alpha1_Limit_To_eventratelimit_Limit(in *Limit, out *eventratelimit.Limit, s conversion.Scope) error

Convert_v1alpha1_Limit_To_eventratelimit_Limit is an autogenerated conversion function.

func RegisterConversions

func RegisterConversions(s *runtime.Scheme) error

RegisterConversions adds conversion functions to the given scheme. Public to allow building arbitrary schemes.

func RegisterDefaults

func RegisterDefaults(scheme *runtime.Scheme) error

RegisterDefaults adds defaulters functions to the given scheme. Public to allow building arbitrary schemes. All generated defaulters are covering - they call all nested defaulters.

func SetDefaults_Configuration

func SetDefaults_Configuration(obj *Configuration)

func SetObjectDefaults_Configuration

func SetObjectDefaults_Configuration(in *Configuration)

Types

type Configuration

type Configuration struct {
	metav1.TypeMeta `json:",inline"`

	// limits are the limits to place on event queries received.
	// Limits can be placed on events received server-wide, per namespace,
	// per user, and per source+object.
	// At least one limit is required.
	Limits []Limit `json:"limits"`
}

Configuration provides configuration for the EventRateLimit admission controller.

func (*Configuration) DeepCopy

func (in *Configuration) DeepCopy() *Configuration

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

func (*Configuration) DeepCopyInto

func (in *Configuration) DeepCopyInto(out *Configuration)

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

func (*Configuration) DeepCopyObject

func (in *Configuration) DeepCopyObject() runtime.Object

DeepCopyObject is an autogenerated deepcopy function, copying the receiver, creating a new runtime.Object.

type Limit

type Limit struct {
	// type is the type of limit to which this configuration applies
	Type LimitType `json:"type"`

	// qps is the number of event queries per second that are allowed for this
	// type of limit. The qps and burst fields are used together to determine if
	// a particular event query is accepted. The qps determines how many queries
	// are accepted once the burst amount of queries has been exhausted.
	QPS int32 `json:"qps"`

	// burst is the burst number of event queries that are allowed for this type
	// of limit. The qps and burst fields are used together to determine if a
	// particular event query is accepted. The burst determines the maximum size
	// of the allowance granted for a particular bucket. For example, if the burst
	// is 10 and the qps is 3, then the admission control will accept 10 queries
	// before blocking any queries. Every second, 3 more queries will be allowed.
	// If some of that allowance is not used, then it will roll over to the next
	// second, until the maximum allowance of 10 is reached.
	Burst int32 `json:"burst"`

	// cacheSize is the size of the LRU cache for this type of limit. If a bucket
	// is evicted from the cache, then the allowance for that bucket is reset. If
	// more queries are later received for an evicted bucket, then that bucket
	// will re-enter the cache with a clean slate, giving that bucket a full
	// allowance of burst queries.
	//
	// The default cache size is 4096.
	//
	// If limitType is 'server', then cacheSize is ignored.
	// +optional
	CacheSize int32 `json:"cacheSize,omitempty"`
}

Limit is the configuration for a particular limit type

func (*Limit) DeepCopy

func (in *Limit) DeepCopy() *Limit

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

func (*Limit) DeepCopyInto

func (in *Limit) DeepCopyInto(out *Limit)

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

type LimitType

type LimitType string

LimitType is the type of the limit (e.g., per-namespace)

const (
	// ServerLimitType is a type of limit where there is one bucket shared by
	// all of the event queries received by the API Server.
	ServerLimitType LimitType = "Server"
	// NamespaceLimitType is a type of limit where there is one bucket used by
	// each namespace
	NamespaceLimitType LimitType = "Namespace"
	// UserLimitType is a type of limit where there is one bucket used by each
	// user
	UserLimitType LimitType = "User"
	// SourceAndObjectLimitType is a type of limit where there is one bucket used
	// by each combination of source and involved object of the event.
	SourceAndObjectLimitType LimitType = "SourceAndObject"
)
