type Manager

type Manager interface {
	// Get configmap by configmap namespace and name.
	GetConfigMap(namespace, name string) (*v1.ConfigMap, error)

	// RegisterPod registers all configmaps from a given pod.
	RegisterPod(pod *v1.Pod)

	// UnregisterPod unregisters configmaps from a given pod that are not
	// used by any other registered pod.
	UnregisterPod(pod *v1.Pod)

func NewCachingConfigMapManager

func NewCachingConfigMapManager(kubeClient clientset.Interface, getTTL manager.GetObjectTTLFunc) Manager

NewCachingConfigMapManager creates a manager that keeps a cache of all configmaps necessary for registered pods. It implement the following logic:

• whenever a pod is create or updated, the cached versions of all configmaps are invalidated
• every GetObject() call tries to fetch the value from local cache; if it is not there, invalidated or too old, we fetch it from apiserver and refresh the value in cache; otherwise it is just fetched from cache

func NewFakeManager

func NewFakeManager() Manager

func NewSimpleConfigMapManager

func NewSimpleConfigMapManager(kubeClient clientset.Interface) Manager

func NewWatchingConfigMapManager

func NewWatchingConfigMapManager(kubeClient clientset.Interface) Manager

NewWatchingConfigMapManager creates a manager that keeps a cache of all configmaps necessary for registered pods. It implements the following logic:

• whenever a pod is created or updated, we start inidvidual watches for all referenced objects that aren't referenced from other registered pods
• every GetObject() returns a value from local cache propagated via watches
