Functions

func AddFlags

func AddFlags(flags *pflag.FlagSet, options *VirtualClusterOptions)

func DisableMissingAPIs

func DisableMissingAPIs(discoveryClient discovery.DiscoveryInterface, controllers sets.Set[string]) (sets.Set[string], error)

DisableMissingAPIs checks if the apis are enabled, if any are missing, disable the syncer and print a log

func ParseControllers

func ParseControllers(options *VirtualClusterOptions) (sets.Set[string], error)
