func GenerateContainersReadyCondition Uses

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

GenerateContainersReadyCondition returns the status of "ContainersReady" condition. The status of "ContainersReady" condition is true when all containers are ready.

func GeneratePodInitializedCondition Uses

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 Uses

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

GeneratePodReadyCondition returns "Ready" condition of a pod. The status of "Ready" condition is "True", if all containers in a pod are ready AND all matching conditions specified in the ReadinessGates have status equal to "True".

func NeedToReconcilePodReadiness Uses

func NeedToReconcilePodReadiness(pod *v1.Pod) bool

NeedToReconcilePodReadiness returns if the pod "Ready" condition need to be reconcile

type Manager Uses

type Manager interface {

    // Start the API server status sync loop.

    // 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)

    // SetContainerStartup updates the cached container status with the given startup, and
    // triggers a status update.
    SetContainerStartup(podUID types.UID, containerID kubecontainer.ContainerID, started 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 Uses

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

NewManager returns a functional Manager.

type PodDeletionSafetyProvider Uses

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

PodDeletionSafetyProvider provides guarantees that a pod can be safely deleted.

type PodStatusProvider Uses

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.
