type Plankton ¶

type Plankton struct {
	Next plugin.Handler
	Pool *redis.Pool
	Path string
	Zone Zone

	Ttl uint32

	LastZoneUpdate time.Time

	MaxRespRec int
	// contains filtered or unexported fields
}

Plankton is an plankton plugin to show how to write a plugin. Redis struct policy types:

1 = round-robin,
2 = ordered
3 = geolocation

func (*Plankton) HashID ¶

func (p *Plankton) HashID(s string) string

func (*Plankton) LoadZoneFromFile ¶

func (p *Plankton) LoadZoneFromFile() error

func (*Plankton) Name ¶

func (p *Plankton) Name() string

Name implements the Handler interface.

func (*Plankton) Ready ¶

func (p *Plankton) 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 (*Plankton) ServeDNS ¶

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

ServeDNS implements the plugin.Handler interface. This method gets called when plankton is used in a Server.

type Record ¶

type Record struct {
	Policy    int            `json:"policy,omitempty"`
	StickyTTL int            `json:"stickyttl,omitempty"`
	A         []A_Record     `json:"a,omitempty"`
	AAAA      []AAAA_Record  `json:"aaaa,omitempty"`
	TXT       []TXT_Record   `json:"txt,omitempty"`
	CNAME     []CNAME_Record `json:"cname,omitempty"`
	NS        []NS_Record    `json:"ns,omitempty"`
	MX        []MX_Record    `json:"mx,omitempty"`
	SRV       []SRV_Record   `json:"srv,omitempty"`
	CAA       []CAA_Record   `json:"caa,omitempty"`
	SOA       []SOA_Record   `json:"soa,omitempty"`
}

Record Struct with all types

type ResponsePrinter ¶

type ResponsePrinter struct {
	dns.ResponseWriter
}

ResponsePrinter wrap a dns.ResponseWriter and will write plankton to standard output when WriteMsg is called.

func NewResponsePrinter ¶

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 "plankton" to standard output.

type SOA_Record ¶

type SOA_Record struct {
	Seq      int    `json:"seq,omitempty"`
	Ttl      uint32 `json:"ttl,omitempty"`
	Ns       string `json:"ns"`
	MBox     string `json:"MBox"`
	Refresh  uint32 `json:"refresh"`
	Retry    uint32 `json:"retry"`
	Expire   uint32 `json:"expire"`
	MinTtl   uint32 `json:"minttl"`
	GslbW    uint32 `json:"gslbw,omitempty"`
	Location uint32 `json:"location,omitempty"`
	HashId   string `json:"hashid,omitempty"`
}
