Constants

const (
	// ConfigName is the name of the configmap
	DefaultsConfigName    = "config-defaults"
	DefaultTimeoutMinutes = 60
)

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
}

Config holds the collection of configurations that we attach to contexts. +k8s:deepcopy-gen=false

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.

type Defaults

type Defaults struct {
	DefaultTimeoutMinutes int
}

Defaults holds the default configurations +k8s:deepcopy-gen=true

func NewDefaultsFromConfigMap

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

NewDefaultsFromConfigMap returns a Config for the given configmap

func NewDefaultsFromMap

func NewDefaultsFromMap(cfgMap map[string]string) (*Defaults, error)

NewDefaultsFromMap returns a Config given a map corresponding to a ConfigMap

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) Equals

func (cfg *Defaults) Equals(other *Defaults) bool

Equals returns true if two Configs are identical

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.
