func Setup(c *caddy.Controller) error

Types

type ETCD

type ETCD struct {
	Next          plugin.Handler
	Fall          fall.F
	Zones         []string
	PathPrefix    string
	Upstream      *upstream.Upstream
	Client        *etcdcv3.Client
	WildcardBound int8 // Calculate the boundary of WildcardDNS
	// contains filtered or unexported fields
}

func (*ETCD) IsNameError

func (e *ETCD) IsNameError(err error) bool

IsNameError implements the ServiceBackend interface.

func (*ETCD) Lookup

func (e *ETCD) Lookup(ctx context.Context, state request.Request, name string, typ uint16) (*dns.Msg, error)

Lookup implements the ServiceBackend interface.

func (*ETCD) MinTTL

func (e *ETCD) MinTTL(state request.Request) uint32

MinTTL implements the Transferer interface.

func (*ETCD) Name

func (e *ETCD) Name() string

Name implements the Handler interface.

func (*ETCD) Records

func (e *ETCD) Records(ctx context.Context, state request.Request, exact bool) ([]msg.Service, error)

Records looks up records in etcd. If exact is true, it will lookup just this name. This is used when find matches when completing SRV lookups for instance.

func (*ETCD) Reverse

func (e *ETCD) Reverse(ctx context.Context, state request.Request, exact bool, opt plugin.Options) ([]msg.Service, error)

Reverse implements the ServiceBackend interface.

func (*ETCD) Serial

func (e *ETCD) Serial(state request.Request) uint32

Serial implements the Transferer interface.

func (*ETCD) ServeDNS

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

ServeDNS implements the plugin.Handler interface.

func (*ETCD) Services

func (e *ETCD) Services(ctx context.Context, state request.Request, exact bool, opt plugin.Options) ([]msg.Service, error)

Services implements the ServiceBackend interface.

func (*ETCD) TTL

func (e *ETCD) TTL(kv *mvccpb.KeyValue, serv *msg.Service) uint32

TTL returns the smaller of the etcd TTL and the service's TTL. If neither of these are set (have a zero value), a default is used.

func (*ETCD) Transfer

func (e *ETCD) Transfer(ctx context.Context, state request.Request) (int, error)

Transfer implements the Transferer interface.
