Functions

func DefaultCheckInPlaceUpdateCompleted

func DefaultCheckInPlaceUpdateCompleted(pod *v1.Pod) error

DefaultCheckInPlaceUpdateCompleted checks whether imageID in pod status has been changed since in-place update. If the imageID in containerStatuses has not been changed, we assume that kubelet has not updated containers in Pod.

func GetCondition

func GetCondition(pod *v1.Pod) *v1.PodCondition

GetCondition returns the InPlaceUpdateReady condition in Pod.

func GetTemplateFromRevision

func GetTemplateFromRevision(revision *apps.ControllerRevision) (*v1.PodTemplateSpec, error)

GetTemplateFromRevision returns the pod template parsed from ControllerRevision.

func InjectReadinessGate

func InjectReadinessGate(pod *v1.Pod)

InjectReadinessGate injects InPlaceUpdateReady into pod.spec.readinessGates
