Functions

func Domain

func Domain(s string) string

Domain is the opposite of Path.

func Path

func Path(s string) string

Path converts a domainname to an etcd path. If s looks like service.staging.skydns.local., the resulting key will be /skydns/local/skydns/staging/service .

func PathWithWildcard

func PathWithWildcard(s string) (string, bool)

As Path, but if a name contains wildcards (*), the name will be chopped of before the (first) wildcard, and we do a highler evel search and later find the matching names. So service.*.skydns.local, will look for all services under skydns.local and will later check for names that match service.*.skydns.local. If a wildcard is found the returned bool is true.

Types

type Service

type Service struct {
	Host     string `json:"host,omitempty"`
	Port     int    `json:"port,omitempty"`
	Priority int    `json:"priority,omitempty"`
	Weight   int    `json:"weight,omitempty"`
	Ttl      uint32 `json:"ttl,omitempty"`
	// etcd key where we found this service and ignore from json un-/marshalling
	Key string `json:"-"`
}

This *is* the rdata from a SRV record, but with a twist. Host (Target in SRV) must be a domain name, but if it looks like an IP address (4/6), we will treat it like an IP address.

func (*Service) NewA

func (s *Service) NewA(name string, ip net.IP) *dns.A

NewA returns a new A record based on the Service.

func (*Service) NewAAAA

func (s *Service) NewAAAA(name string, ip net.IP) *dns.AAAA

NewAAAA returns a new AAAA record based on the Service.

func (*Service) NewCNAME

func (s *Service) NewCNAME(name string, target string) *dns.CNAME

NewCNAME returns a new CNAME record based on the Service.

func (*Service) NewNS

func (s *Service) NewNS(name string, target string) *dns.NS

NewNS returns a new NS record based on the Service.

func (*Service) NewPTR

func (s *Service) NewPTR(name string, ttl uint32) *dns.PTR

NewPTR returns a new PTR record based on the Service.

func (*Service) NewSRV

func (s *Service) NewSRV(name string, weight uint16) *dns.SRV

NewSRV returns a new SRV record based on the Service.
