	ClientConfig clientcmd.ClientConfig
	// contains filtered or unexported fields
}

func New

func New(zones []string) *Multicluster_gw

func ParseStanza

func ParseStanza(c *caddy.Controller) (*Multicluster_gw, error)

ParseStanza parses a kubernetes stanza

func (Multicluster_gw) IsNameError

func (m Multicluster_gw) IsNameError(err error) bool

IsNameError returns true if err indicated a record not found condition

func (Multicluster_gw) Name

func (m Multicluster_gw) Name() string

Name implements the Handler interface.

func (Multicluster_gw) Ready

func (m Multicluster_gw) Ready() bool

Ready implements the ready.Readiness interface, once this flips to true CoreDNS assumes this plugin is ready for queries; it is not checked again.

func (Multicluster_gw) ServeDNS

func (m Multicluster_gw) ServeDNS(ctx context.Context, w dns.ResponseWriter, r *dns.Msg) (int, error)

ServeDNS implements the plugin.Handler interface.

type ResponsePrinter

func NewResponsePrinter(w dns.ResponseWriter) *ResponsePrinter

NewResponsePrinter returns ResponseWriter.

func (*ResponsePrinter) WriteMsg

func (r *ResponsePrinter) WriteMsg(res *dns.Msg) error

WriteMsg calls the underlying ResponseWriter's WriteMsg method and prints "example" to standard output.
