Functions

func ToContext

func ToContext(ctx context.Context, c *Config) context.Context

ToContext attaches the provided Config to the provided context, returning the new context with the Config attached.

Types

type Config

type Config struct {
	Defaults   *Defaults
	Features   *Features
	Autoscaler *autoscalerconfig.Config
}

Config holds the collection of configurations that we attach to contexts.

func FromContext

func FromContext(ctx context.Context) *Config

FromContext extracts a Config from the provided context.

func FromContextOrDefaults

func FromContextOrDefaults(ctx context.Context) *Config

FromContextOrDefaults is like FromContext, but when no Config is attached it returns a Config populated with the defaults for each of the Config fields.

func (*Config) DeepCopy

func (in *Config) DeepCopy() *Config

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

func (*Config) DeepCopyInto

func (in *Config) DeepCopyInto(out *Config)

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

type Defaults

type Defaults struct {
	RevisionTimeoutSeconds int64
	// This is the timeout set for ingress.
	// RevisionTimeoutSeconds must be less than this value.
	MaxRevisionTimeoutSeconds int64

	UserContainerNameTemplate string

	ContainerConcurrency int64

	// ContainerConcurrencyMaxLimit is the maximum permitted container concurrency
	// or target value in the system.
	ContainerConcurrencyMaxLimit int64

	// AllowContainerConcurrencyZero determines whether users are permitted to specify
	// a containerConcurrency of 0 (i.e. unbounded).
	AllowContainerConcurrencyZero bool

	// Permits defaulting of `enableServiceLinks` pod spec field.
	// See: https://github.com/knative/serving/issues/8498 for details.
	EnableServiceLinks *bool

	RevisionCPURequest              *resource.Quantity
	RevisionCPULimit                *resource.Quantity
	RevisionMemoryRequest           *resource.Quantity
	RevisionMemoryLimit             *resource.Quantity
	RevisionEphemeralStorageRequest *resource.Quantity
	RevisionEphemeralStorageLimit   *resource.Quantity
}

Defaults includes the default values to be populated by the webhook.

func NewDefaultsConfigFromConfigMap

func NewDefaultsConfigFromConfigMap(config *corev1.ConfigMap) (*Defaults, error)

NewDefaultsConfigFromConfigMap creates a Defaults from the supplied configMap.

func NewDefaultsConfigFromMap

func NewDefaultsConfigFromMap(data map[string]string) (*Defaults, error)

NewDefaultsConfigFromMap creates a Defaults from the supplied Map.

func (*Defaults) DeepCopy

func (in *Defaults) DeepCopy() *Defaults

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

func (*Defaults) DeepCopyInto

func (in *Defaults) DeepCopyInto(out *Defaults)

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

func (*Defaults) UserContainerName

func (d *Defaults) UserContainerName(ctx context.Context) string

UserContainerName returns the name of the user container based on the context.

type Features

type Features struct {
	MultiContainer          Flag
	PodSpecAffinity         Flag
	PodSpecDryRun           Flag
	PodSpecFieldRef         Flag
	PodSpecHostAliases      Flag
	PodSpecNodeSelector     Flag
	PodSpecRuntimeClassName Flag
	PodSpecSecurityContext  Flag
	PodSpecTolerations      Flag
	TagHeaderBasedRouting   Flag
	AutoDetectHTTP2         Flag
}

Features specifies which features are allowed by the webhook.

func NewFeaturesConfigFromConfigMap

func NewFeaturesConfigFromConfigMap(config *corev1.ConfigMap) (*Features, error)

NewFeaturesConfigFromConfigMap creates a Features from the supplied ConfigMap

func NewFeaturesConfigFromMap

func NewFeaturesConfigFromMap(data map[string]string) (*Features, error)

NewFeaturesConfigFromMap creates a Features from the supplied Map

func (*Features) DeepCopy

func (in *Features) DeepCopy() *Features

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

func (*Features) DeepCopyInto

func (in *Features) DeepCopyInto(out *Features)

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

type Flag

type Flag string

Flag is a string value which can be either Enabled, Disabled, or Allowed.

const (
	// FeaturesConfigName is the name of the ConfigMap for the features.
	FeaturesConfigName = "config-features"

	// Enabled turns on an optional behavior.
	Enabled Flag = "Enabled"
	// Disabled turns off an optional behavior.
	Disabled Flag = "Disabled"
	// Allowed neither explicitly disables or enables a behavior.
	// eg. allow a client to control behavior with an annotation or allow a new value through validation.
	Allowed Flag = "Allowed"
)

type Store

type Store struct {
	*configmap.UntypedStore
}

Store is a typed wrapper around configmap.Untyped store to handle our configmaps. +k8s:deepcopy-gen=false

func NewStore

func NewStore(logger configmap.Logger, onAfterStore ...func(name string, value interface{})) *Store

NewStore creates a new store of Configs and optionally calls functions when ConfigMaps are updated.

func (*Store) Load

func (s *Store) Load() *Config

Load creates a Config from the current config state of the Store.

func (*Store) ToContext

func (s *Store) ToContext(ctx context.Context) context.Context

ToContext attaches the current Config state to the provided context.
