Types

type Backend

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

func NewBackend

func NewBackend(client etcd.KeysAPI, ctx context.Context, config *Config) *Backend

NewBackend returns a new Backend for SkyDNS, backed by etcd.

func (*Backend) Client

func (g *Backend) Client() etcd.KeysAPI

Client exposes the underlying Etcd client (used in tests).

func (*Backend) HasSynced

func (g *Backend) HasSynced() bool

func (*Backend) Records

func (g *Backend) Records(name string, requesterID string, exact bool) ([]msg.Service, error)

func (*Backend) ReverseRecord

func (g *Backend) ReverseRecord(name string) (*msg.Service, error)

func (*Backend) TranslateForwardedRequest

func (g *Backend) TranslateForwardedRequest(name string, requesterIP string, req *dns.Msg) (*dns.Msg, error)

func (*Backend) TranslateForwardedResponse

func (g *Backend) TranslateForwardedResponse(name string, responderIP string, req, resp *dns.Msg) (*dns.Msg, error)

type Config

type Config struct {
	Ttl      uint32
	Priority uint16
}

Config represents configuration for the Etcd backend - these values should be taken directly from server.Config
