func EtcdKeyForHost ¶ Uses

func EtcdKeyForHost(hostname string) string

func NewSourceEtcd ¶ Uses

func NewSourceEtcd(key string, client tools.EtcdClient, updates chan<- interface{})

NewSourceEtcd creates a config source that watches and pulls from a key in etcd

func NewSourceFile ¶ Uses

func NewSourceFile(path string, period time.Duration, updates chan<- interface{})

func NewSourceURL ¶ Uses

func NewSourceURL(url string, period time.Duration, updates chan<- interface{})

type PodConfig ¶ Uses

type PodConfig struct {
    // contains filtered or unexported fields
}

PodConfig is a configuration mux that merges many sources of pod configuration into a single consistent structure, and then delivers incremental change notifications to listeners in order.

func NewPodConfig ¶ Uses

func NewPodConfig(mode PodConfigNotificationMode) *PodConfig

NewPodConfig creates an object that can merge many configuration sources into a stream of normalized updates to a pod configuration.

func (*PodConfig) Channel ¶ Uses

func (c *PodConfig) Channel(source string) chan<- interface{}

Channel creates or returns a config source channel. The channel only accepts PodUpdates

func (*PodConfig) Sync ¶ Uses

func (c *PodConfig) Sync()

Sync requests the full configuration be delivered to the update channel.

func (*PodConfig) Updates ¶ Uses

func (c *PodConfig) Updates() <-chan kubelet.PodUpdate

Updates returns a channel of updates to the configuration, properly denormalized.

type PodConfigNotificationMode ¶ Uses

type PodConfigNotificationMode int

PodConfigNotificationMode describes how changes are sent to the update channel.
