Functions

func UpdateTortoiseAutoscalingPolicyInStatus

func UpdateTortoiseAutoscalingPolicyInStatus(tortoise *v1beta3.Tortoise, hpa *v2.HorizontalPodAutoscaler, now time.Time) *v1beta3.Tortoise

UpdateTortoiseAutoscalingPolicyInStatus updates .status.autoscalingPolicy based on the policy in .spec.autoscalingPolicy, and the existing container names in the workload.

Types

type Service

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

func New

func New(c client.Client, recorder record.EventRecorder, rangeOfMinMaxReplicasRecommendationHour int, timeZone string, tortoiseUpdateInterval time.Duration, gatheringDataDuration string) (*Service, error)

func (*Service) AddFinalizer

func (s *Service) AddFinalizer(ctx context.Context, tortoise *v1beta3.Tortoise) (*v1beta3.Tortoise, error)

func (*Service) GetTortoise

func (s *Service) GetTortoise(ctx context.Context, namespacedName types.NamespacedName) (*v1beta3.Tortoise, error)

func (*Service) ListTortoise

func (s *Service) ListTortoise(ctx context.Context, namespaceName string) (*v1beta3.TortoiseList, error)

func (*Service) RecordReconciliationFailure

func (s *Service) RecordReconciliationFailure(t *v1beta3.Tortoise, err error, now time.Time) *v1beta3.Tortoise

func (*Service) RemoveFinalizer

func (s *Service) RemoveFinalizer(ctx context.Context, tortoise *v1beta3.Tortoise) error

func (*Service) ShouldReconcileTortoiseNow

func (s *Service) ShouldReconcileTortoiseNow(tortoise *v1beta3.Tortoise, now time.Time) (bool, time.Duration)

func (*Service) UpdateContainerRecommendationFromVPA

func (s *Service) UpdateContainerRecommendationFromVPA(tortoise *v1beta3.Tortoise, vpa *v1.VerticalPodAutoscaler, now time.Time) *v1beta3.Tortoise

func (*Service) UpdateResourceRequest

func (c *Service) UpdateResourceRequest(ctx context.Context, tortoise *v1beta3.Tortoise, replica int32, now time.Time) (
	*v1beta3.Tortoise,
	error,
)

UpdateResourceRequest updates pods' resource requests based on the calculated recommendation. Updated ContainerResourceRequests will be used in the next mutating webhook of Pods. It updates ContainerResourceRequests in the status of the Tortoise, when ALL the following conditions are met:

• UpdateMode is Auto
• Any of the recommended resource request is increased, OR, all the recommended resource request is decreased, but it's been a while (1h) after the last update.

func (*Service) UpdateTortoisePhase

func (s *Service) UpdateTortoisePhase(tortoise *v1beta3.Tortoise, now time.Time) *v1beta3.Tortoise

func (*Service) UpdateTortoiseStatus

func (s *Service) UpdateTortoiseStatus(ctx context.Context, originalTortoise *v1beta3.Tortoise, now time.Time, timeRecord bool) (*v1beta3.Tortoise, error)
