Functions

func Register added in v1.4.0

func Register()

Register all metrics.

Types

type GarbageCollector

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

GarbageCollector is responsible for carrying out cascading deletion, and removing ownerReferences from the dependents if the owner is deleted with DeleteOptions.OrphanDependents=true.

func NewGarbageCollector

func NewGarbageCollector(metaOnlyClientPool dynamic.ClientPool, clientPool dynamic.ClientPool, mapper meta.RESTMapper, resources []unversioned.GroupVersionResource) (*GarbageCollector, error)

func (*GarbageCollector) GraphHasUID

func (gc *GarbageCollector) GraphHasUID(UIDs []types.UID) bool

*FOR TEST USE ONLY* It's not safe to call this function when the GC is still busy. GraphHasUID returns if the Propagator has a particular UID store in its uidToNode graph. It's useful for debugging.

func (*GarbageCollector) Run

func (gc *GarbageCollector) Run(workers int, stopCh <-chan struct{})

type Propagator

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

type RegisteredRateLimiter added in v1.4.0

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

RegisteredRateLimiter records the registered RateLimters to avoid duplication.

func NewRegisteredRateLimiter added in v1.4.0

func NewRegisteredRateLimiter(resources []unversioned.GroupVersionResource) *RegisteredRateLimiter

NewRegisteredRateLimiter returns a new RegisteredRateLimiater. TODO: NewRegisteredRateLimiter is not dynamic. We need to find a better way when GC dynamically change the resources it monitors.

type UIDCache added in v1.4.0

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

UIDCache is an LRU cache for uid.

func NewUIDCache added in v1.4.0

func NewUIDCache(maxCacheEntries int) *UIDCache

NewUIDCache returns a UIDCache.

func (*UIDCache) Add added in v1.4.0

func (c *UIDCache) Add(uid types.UID)

Add adds a uid to the cache.

func (*UIDCache) Has added in v1.4.0

func (c *UIDCache) Has(uid types.UID) bool

Has returns if a uid is in the cache.
