Functions

func CheckInPlaceUpdateCompleted

func CheckInPlaceUpdateCompleted(pod *v1.Pod) error

CheckInPlaceUpdateCompleted 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.

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
