Functions

func BuildMultiClusterResourceVersion

func BuildMultiClusterResourceVersion(clusterResourceMap map[string]string) string

BuildMultiClusterResourceVersion build multi cluster resource version.

func RecoverClusterResourceVersion

func RecoverClusterResourceVersion(obj runtime.Object, cluster string) bool

RecoverClusterResourceVersion convert global resource version to single cluster resource version. If obj is updated, return true.

func RemoveCacheSourceAnnotation

func RemoveCacheSourceAnnotation(obj runtime.Object) bool

RemoveCacheSourceAnnotation delete CacheSourceAnnotationKey annotation in object. If obj is updated, return true.

Types

type MultiClusterCache

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

MultiClusterCache caches resource from multi member clusters

func NewMultiClusterCache

func NewMultiClusterCache(newClientFunc func(string) (dynamic.Interface, error), restMapper meta.RESTMapper) *MultiClusterCache

NewMultiClusterCache return a cache for resources from member clusters

func (*MultiClusterCache) Get

func (c *MultiClusterCache) Get(ctx context.Context, gvr schema.GroupVersionResource, name string, options *metav1.GetOptions) (runtime.Object, error)

Get returns the target object

func (*MultiClusterCache) GetResourceFromCache

func (c *MultiClusterCache) GetResourceFromCache(ctx context.Context, gvr schema.GroupVersionResource, namespace, name string) (runtime.Object, string, error)

GetResourceFromCache returns which cluster the resource belong to.

func (*MultiClusterCache) HasResource

func (c *MultiClusterCache) HasResource(resource schema.GroupVersionResource) bool

HasResource return whether resource is cached.

func (*MultiClusterCache) List

func (c *MultiClusterCache) List(ctx context.Context, gvr schema.GroupVersionResource, o *metainternalversion.ListOptions) (runtime.Object, error)

List returns the object list nolint:gocyclo

func (*MultiClusterCache) Stop

func (c *MultiClusterCache) Stop()

Stop stops the cache for multi cluster.

func (*MultiClusterCache) UpdateCache

func (c *MultiClusterCache) UpdateCache(resourcesByCluster map[string]map[schema.GroupVersionResource]*MultiNamespace) error

UpdateCache update cache for multi clusters

func (*MultiClusterCache) Watch

func (c *MultiClusterCache) Watch(ctx context.Context, gvr schema.GroupVersionResource, options *metainternalversion.ListOptions) (watch.Interface, error)

Watch watches the resource

type MultiNamespace

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

MultiNamespace contains multiple namespaces.

func NewMultiNamespace

func NewMultiNamespace() *MultiNamespace

NewMultiNamespace return a new empty MultiNamespace.

func (*MultiNamespace) Add

func (n *MultiNamespace) Add(ns string)

Add adds ns.

func (*MultiNamespace) Contains

func (n *MultiNamespace) Contains(ns string) bool

Contains returns if ns is covered by MultiNamespace. NamespaceAll covers all.

func (*MultiNamespace) Equal

func (n *MultiNamespace) Equal(another *MultiNamespace) bool

Equal tell whether two MultiNamespace has the same namespaces.

func (*MultiNamespace) Single

func (n *MultiNamespace) Single() (string, bool)

Single returns ns name and true when only one namespace in MultiNamespace. NamespaceAll returns false.

type Store

type Store interface {
	UpdateCache(resourcesByCluster map[string]map[schema.GroupVersionResource]*MultiNamespace) error
	HasResource(resource schema.GroupVersionResource) bool
	GetResourceFromCache(ctx context.Context, gvr schema.GroupVersionResource, namespace, name string) (runtime.Object, string, error)
	Stop()

	Get(ctx context.Context, gvr schema.GroupVersionResource, name string, options *metav1.GetOptions) (runtime.Object, error)
	List(ctx context.Context, gvr schema.GroupVersionResource, options *metainternalversion.ListOptions) (runtime.Object, error)
	Watch(ctx context.Context, gvr schema.GroupVersionResource, options *metainternalversion.ListOptions) (watch.Interface, error)
}

Store is the cache for resources from multiple member clusters
