Functions

func DiscoverServiceCIDRByInvalidServiceCreation

func DiscoverServiceCIDRByInvalidServiceCreation(ctx context.Context, k8sClient client.Client, namespace string) (string, error)

DiscoverServiceCIDRByInvalidServiceCreation creates an invalid Service to get returned error, and analyzes the error message to get Service CIDR. TODO: add dual-stack support.

func FilterEndpointSubsets

func FilterEndpointSubsets(subsets []corev1.EndpointSubset) []corev1.EndpointSubset

FilterEndpointSubsets keeps IPs only and removes other fields from EndpointSubset which are unnecessary information for other member clusters.

func GetServiceEndpointPorts

func GetServiceEndpointPorts(ports []corev1.ServicePort) []corev1.EndpointPort

GetServiceEndpointPorts converts Service's port to EndpointPort

func GetServiceEndpointSubset

func GetServiceEndpointSubset(svc *corev1.Service) corev1.EndpointSubset

func HashLabelIdentity

func HashLabelIdentity(l string) string

HashLabelIdentity generates a hash value for label identity string.

func IsMulticlusterService

func IsMulticlusterService(service *corev1.Service) bool

func NamespacedName

func NamespacedName(namespace, name string) string

TODO: Use NamespacedName stringer method instead of this. e.g. nsName.String()

func NewClusterInfoResourceExportName

func NewClusterInfoResourceExportName(clusterID string) string

func RemoveStringFromSlice

func RemoveStringFromSlice(slice []string, s string) (result []string)

func StringExistsInSlice

func StringExistsInSlice(slice []string, s string) bool

func ToMCResourceName

func ToMCResourceName(originalResourceName string) string

func ValidateLocalClusterClaim

func ValidateLocalClusterClaim(c client.Client, clusterSet *multiclusterv1alpha1.ClusterSet) (clusterID ClusterID, clusterSetID ClusterSetID, err error)
