Overview ¶
Package plugin is the package that defines the eviction strategy, and those strategies must implement EvictPlugin interface, supporting both embedded plugin and external registered plugin.

type EvictionPlugin ¶
type EvictionPlugin interface { Name() string endpointpkg.Endpoint }
EvictionPlugin performs eviction actions based on agent resources.
func NewReclaimedResourcesEvictionPlugin ¶
func NewReclaimedResourcesEvictionPlugin(_ *client.GenericClientSet, _ events.EventRecorder, metaServer *metaserver.MetaServer, emitter metrics.MetricEmitter, conf *config.Configuration) EvictionPlugin
type InitFunc ¶
type InitFunc func(genericClient *client.GenericClientSet, recorder events.EventRecorder, metaServer *metaserver.MetaServer, emitter metrics.MetricEmitter, conf *config.Configuration) EvictionPlugin
InitFunc is used to initialize a particular innter eviction plugin.
type ResourcesEvictionPlugin ¶
type ResourcesEvictionPlugin struct {
// contains filtered or unexported fields
}
ResourcesEvictionPlugin implements EvictPlugin interface it trigger pod eviction logic based on the tolerance of resources.
func NewResourcesEvictionPlugin ¶
func NewResourcesEvictionPlugin(pluginName string, metaServer *metaserver.MetaServer, emitter metrics.MetricEmitter, resourcesGetter ResourcesGetter, thresholdGetter ThresholdGetter, skipZeroQuantityResourceNames sets.String, podFilter func(pod *v1.Pod) (bool, error), evictionPodGracefulPeriod int64) *ResourcesEvictionPlugin

func (b *ResourcesEvictionPlugin) Name() string
func (*ResourcesEvictionPlugin) ThresholdMet ¶
func (b *ResourcesEvictionPlugin) ThresholdMet(ctx context.Context) (*pluginapi.ThresholdMetResponse, error)
ThresholdMet evict pods when the beset effort resources usage is greater than the supply (after considering toleration).
