package dns

import "k8s.io/kubernetes/pkg/dns"

Package DNS provides a backend for the skydns DNS server started by the kubedns cluster addon. It exposes the 2 interface method: Records and ReverseRecord, which skydns invokes according to the DNS queries it receives. It serves these records by consulting an in memory tree populated with Kubernetes Services and Endpoints received from the Kubernetes API server.

Types ¶

type KubeDNS ¶

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

func NewKubeDNS ¶

func NewKubeDNS(client clientset.Interface, domain string, federations map[string]string) (*KubeDNS, error)

func (*KubeDNS) GetCacheAsJSON ¶

func (kd *KubeDNS) GetCacheAsJSON() (string, error)

func (*KubeDNS) Records ¶

func (kd *KubeDNS) Records(name string, exact bool) (retval []skymsg.Service, err error)

Records responds with DNS records that match the given name, in a format understood by the skydns server. If "exact" is true, a single record matching the given name is returned, otherwise all records stored under the subtree matching the name are returned.

func (*KubeDNS) ReverseRecord ¶

func (kd *KubeDNS) ReverseRecord(name string) (*skymsg.Service, error)

ReverseRecords performs a reverse lookup for the given name.

func (*KubeDNS) Start ¶

func (kd *KubeDNS) Start()

type TreeCache ¶

type TreeCache struct {
	ChildNodes map[string]*TreeCache
	Entries    map[string]interface{}
}

func NewTreeCache ¶

func NewTreeCache() *TreeCache

func (*TreeCache) Serialize ¶

func (cache *TreeCache) Serialize() (string, error)
