Types

type AsynchronizedPodKiller

type AsynchronizedPodKiller struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

AsynchronizedPodKiller pushed killing actions into a queue and returns true directly, another go routine will be responsible to perform killing actions instead.

type DeletionAPIKiller

type DeletionAPIKiller struct {
	// contains filtered or unexported fields
}

DeletionAPIKiller implements Killer interface it evict those given pods by calling pod deletion API.

func NewDeletionAPIKiller

type EvictionAPIKiller

type EvictionAPIKiller struct {
	// contains filtered or unexported fields
}

EvictionAPIKiller implements Killer interface it evict those given pods by eviction API, and wait until pods have actually been deleted.

func NewEvictionAPIKiller

func NewEvictionAPIKiller(client kubernetes.Interface, recorder events.EventRecorder) *EvictionAPIKiller

NewEvictionAPIKiller returns a new updater Object.

func (*EvictionAPIKiller) Evict

func (e *EvictionAPIKiller) Evict(ctx context.Context, pod *v1.Pod, gracePeriodSeconds int64, reason string) error

func (*EvictionAPIKiller) Name

func (e *EvictionAPIKiller) Name() string

type Killer

type Killer interface {
	// Name returns name as identifier for a specific Killer.
	Name() string

	// Evict for given pods and corresponding graceful period seconds.
	Evict(ctx context.Context, pod *v1.Pod, gracePeriodSeconds int64, reason string) error
}

Killer implements pod eviction logic.

type PodKiller

type PodKiller interface {
	// Name returns name as identifier for a specific Killer.
	Name() string

	// Start pod killer logic, prepare to receive on-killing pods.
	Start(ctx context.Context)

	// EvictPods send on-killing pods to pod killer.
	EvictPods(rpList rule.RuledEvictPodList) error

	// EvictPod a pod with the specified grace period.
	EvictPod(rp *rule.RuledEvictPod) error
}

PodKiller implements the killing actions for given pods.

type SynchronizedPodKiller

type SynchronizedPodKiller struct {
	// contains filtered or unexported fields
}

SynchronizedPodKiller trigger killing actions immediately after receiving killing requests; only returns true if all pods are successfully evicted.
