IndexFuncServiceRefName is IndexFunc for "ServiceReference" index.

func NewCachedTargetsManager

func NewCachedTargetsManager(elbv2Client services.ELBV2, logger logr.Logger) *cachedTargetsManager

NewCachedTargetsManager constructs new cachedTargetsManager

func NewDefaultResourceManager

func NewDefaultResourceManager(k8sClient client.Client, elbv2Client services.ELBV2,
	podInfoRepo k8s.PodInfoRepo, networkingManager networking.NetworkingManager,
	vpcInfoProvider networking.VPCInfoProvider, multiClusterManager MultiClusterManager, metricsCollector lbcmetrics.MetricCollector,
	vpcID string, failOpenEnabled bool, endpointSliceEnabled bool,
	eventRecorder record.EventRecorder, logger logr.Logger) *defaultResourceManager

NewDefaultResourceManager constructs new defaultResourceManager.

func SaveTGBReconcileCheckpoint

UniqueIDForTargetDescription generates a unique ID to differentiate targets.

Types

type MultiClusterManager

type MultiClusterManager interface {
	// FilterTargetsForDeregistration Given a list of targets, filter the list down to only targets the cluster should operate on.
	FilterTargetsForDeregistration(ctx context.Context, tgb *elbv2api.TargetGroupBinding, targetInfo []TargetInfo) ([]TargetInfo, bool, error)

	// UpdateTrackedIPTargets Update the tracked target set in persistent storage
	UpdateTrackedIPTargets(ctx context.Context, updateRequested bool, endpoints []backend.PodEndpoint, tgb *elbv2api.TargetGroupBinding) error

	// UpdateTrackedInstanceTargets Update the tracked target set in persistent storage
	UpdateTrackedInstanceTargets(ctx context.Context, updateRequested bool, endpoints []backend.NodePortEndpoint, tgb *elbv2api.TargetGroupBinding) error

	// CleanUp Removes any resources used to implement multicluster support.
	CleanUp(ctx context.Context, tgb *elbv2api.TargetGroupBinding) error
}

MultiClusterManager implements logic to support multiple LBCs managing the same Target Group.

func NewMultiClusterManager

func NewMultiClusterManager(kubeClient client.Client, apiReader client.Reader, logger logr.Logger) MultiClusterManager

NewMultiClusterManager constructs a multicluster manager that is immediately ready to use.

type ResourceManager

type ResourceManager interface {
	Reconcile(ctx context.Context, tgb *elbv2api.TargetGroupBinding) (bool, error)
	Cleanup(ctx context.Context, tgb *elbv2api.TargetGroupBinding) error
}

ResourceManager manages the TargetGroupBinding resource.

type TargetInfo

type TargetInfo struct {
	// The target's description
	Target elbv2types.TargetDescription

	// The target's health information.
	// If absent, the target's health information is unknown.
	TargetHealth *elbv2types.TargetHealth
}

TargetInfo contains information about a TargetGroup target.

func (*TargetInfo) GetIdentifier

func (t *TargetInfo) GetIdentifier() string

GetIdentifier this should match backend.Endpoint

func (*TargetInfo) IsDraining

func (t *TargetInfo) IsDraining() bool

IsDraining returns whether target is in draining state.

func (*TargetInfo) IsHealthy

func (t *TargetInfo) IsHealthy() bool

IsHealthy returns whether target is healthy.

func (*TargetInfo) IsInitial

func (t *TargetInfo) IsInitial() bool

IsInitial returns whether target is in initial state.

func (*TargetInfo) IsNotRegistered

func (t *TargetInfo) IsNotRegistered() bool

IsNotRegistered returns whether target is not registered.

type TargetsManager

type TargetsManager interface {
	// Register Targets into TargetGroup.
	RegisterTargets(ctx context.Context, tgb *elbv2api.TargetGroupBinding, targets []elbv2types.TargetDescription) error

	// Deregister Targets from TargetGroup.
	DeregisterTargets(ctx context.Context, tgb *elbv2api.TargetGroupBinding, targets []elbv2types.TargetDescription) error

	// List Targets from TargetGroup.
	ListTargets(ctx context.Context, tgb *elbv2api.TargetGroupBinding) ([]TargetInfo, error)
}

TargetsManager is an abstraction around ELBV2's targets API.
