VirtualClusterConfig wraps the config and adds extra info such as name, serviceName and targetNamespace

func ParseConfig

func ParseConfig(path, name string, setValues []string) (*VirtualClusterConfig, error)

func (VirtualClusterConfig) DisableMissingAPIs

func (v VirtualClusterConfig) DisableMissingAPIs(discoveryClient discovery.DiscoveryInterface) error

func (VirtualClusterConfig) EmbeddedDatabase

func (v VirtualClusterConfig) EmbeddedDatabase() bool

func (VirtualClusterConfig) LegacyOptions

func (v VirtualClusterConfig) LegacyOptions() (*legacyconfig.LegacyVirtualClusterOptions, error)

LegacyOptions converts the config to the legacy cluster options
