type Reconciler ¶
type Reconciler interface {
// Starts running the reconciliation loop which executes periodically, checks
// if volumes that should be mounted are mounted and volumes that should
// be unmounted are unmounted. If not, it will trigger mount/unmount
// operations to rectify.
// If attach/detach management is enabled, the manager will also check if
// volumes that should be attached are attached and volumes that should
// be detached are detached and trigger attach/detach operations as needed.
Run(stopCh <-chan struct{})
// StatesHasBeenSynced returns true only after syncStates process starts to sync
// states at least once after kubelet starts
StatesHasBeenSynced() bool
}
Reconciler runs a periodic loop to reconcile the desired state of the world with the actual state of the world by triggering attach, detach, mount, and unmount operations. Note: This is distinct from the Reconciler implemented by the attach/detach controller. This reconciles state for the kubelet volume manager. That reconciles state for the attach/detach controller.
func NewReconciler ¶
func NewReconciler( kubeClient clientset.Interface, controllerAttachDetachEnabled bool, loopSleepDuration time.Duration, waitForAttachTimeout time.Duration, nodeName types.NodeName, desiredStateOfWorld cache.DesiredStateOfWorld, actualStateOfWorld cache.ActualStateOfWorld, populatorHasAddedPods func() bool, operationExecutor operationexecutor.OperationExecutor, mounter mount.Interface, hostutil hostutil.HostUtils, volumePluginMgr *volumepkg.VolumePluginMgr, kubeletPodsDir string) Reconciler
NewReconciler returns a new instance of Reconciler.
controllerAttachDetachEnabled - if true, indicates that the attach/detach controller is responsible for managing the attach/detach operations for this node, and therefore the volume manager should not
loopSleepDuration - the amount of time the reconciler loop sleeps between successive executions
waitForAttachTimeout - the amount of time the Mount function will wait for the volume to be attached
nodeName - the Name for this node, used by Attach and Detach methods
desiredStateOfWorld - cache containing the desired state of the world
actualStateOfWorld - cache containing the actual state of the world
populatorHasAddedPods - checker for whether the populator has finished adding pods to the desiredStateOfWorld cache at least once after sources are all ready (before sources are ready, pods are probably missing)
operationExecutor - used to trigger attach/detach/mount/unmount operations safely (prevents more than one operation from being triggered on the same volume)
mounter - mounter passed in from kubelet, passed down unmount path
hostutil - hostutil passed in from kubelet
volumePluginMgr - volume plugin manager passed from kubelet
