Functions

func GeneratePodInitializedCondition

func GeneratePodInitializedCondition(spec *v1.PodSpec, containerStatuses []v1.ContainerStatus, podPhase v1.PodPhase) v1.PodCondition

GeneratePodInitializedCondition returns initialized condition if all init containers in a pod are ready, else it returns an uninitialized condition.

func GeneratePodReadyCondition

func GeneratePodReadyCondition(spec *v1.PodSpec, containerStatuses []v1.ContainerStatus, podPhase v1.PodPhase) v1.PodCondition

GeneratePodReadyCondition returns ready condition if all containers in a pod are ready, else it returns an unready condition.

Types

type Manager

type Manager interface {
	PodStatusProvider

	// Start the API server status sync loop.
	Start()

	// SetPodStatus caches updates the cached status for the given pod, and triggers a status update.
	SetPodStatus(pod *v1.Pod, status v1.PodStatus)

	// SetContainerReadiness updates the cached container status with the given readiness, and
	// triggers a status update.
	SetContainerReadiness(podUID types.UID, containerID kubecontainer.ContainerID, ready bool)

	// TerminatePod resets the container status for the provided pod to terminated and triggers
	// a status update.
	TerminatePod(pod *v1.Pod)

	// RemoveOrphanedStatuses scans the status cache and removes any entries for pods not included in
	// the provided podUIDs.
	RemoveOrphanedStatuses(podUIDs map[types.UID]bool)
}

Manager is the Source of truth for kubelet pod status, and should be kept up-to-date with the latest v1.PodStatus. It also syncs updates back to the API server.

func NewManager

func NewManager(kubeClient clientset.Interface, podManager kubepod.Manager, podDeletionSafety PodDeletionSafetyProvider) Manager

type PodDeletionSafetyProvider

type PodDeletionSafetyProvider interface {
	// A function which returns true if the pod can safely be deleted
	OkToDeletePod(pod *v1.Pod) bool
}

An object which provides guarantees that a pod can be saftely deleted.

type PodStatusProvider

type PodStatusProvider interface {
	// GetPodStatus returns the cached status for the provided pod UID, as well as whether it
	// was a cache hit.
	GetPodStatus(uid types.UID) (v1.PodStatus, bool)
}

PodStatusProvider knows how to provide status for a pod. It's intended to be used by other components that need to introspect status.
