Types

type PodsEvictionRestriction

type PodsEvictionRestriction interface {
	// Evict sends eviction instruction to the api client.
	// Returns error if pod cannot be evicted or if client returned error.
	Evict(pod *apiv1.Pod, eventRecorder record.EventRecorder) error
	// CanEvict checks if pod can be safely evicted
	CanEvict(pod *apiv1.Pod) bool
}

PodsEvictionRestriction controls pods evictions. It ensures that we will not evict too many pods from one replica set. For replica set will allow to evict one pod or more if evictionToleranceFraction is configured.

type PodsEvictionRestrictionFactory

type PodsEvictionRestrictionFactory interface {
	// NewPodsEvictionRestriction creates PodsEvictionRestriction for given set of pods,
	// controlled by a single VPA object.
	NewPodsEvictionRestriction(pods []*apiv1.Pod, vpa *vpa_types.VerticalPodAutoscaler) PodsEvictionRestriction
}
