Variables

var DefaultSDConfig = SDConfig{
	RefreshInterval: model.Duration(30 * time.Second),
	Type:            "SRV",
}

DefaultSDConfig is the default DNS SD configuration.

Types

type Discovery

type Discovery struct {
	*refresh.Discovery
	// contains filtered or unexported fields
}

Discovery periodically performs DNS-SD requests. It implements the Discoverer interface.

func NewDiscovery

func NewDiscovery(conf SDConfig, logger log.Logger, metrics discovery.DiscovererMetrics) (*Discovery, error)

NewDiscovery returns a new Discovery which periodically refreshes its targets.

type SDConfig

type SDConfig struct {
	Names           []string       `yaml:"names"`
	RefreshInterval model.Duration `yaml:"refresh_interval,omitempty"`
	Type            string         `yaml:"type"`
	Port            int            `yaml:"port"` // Ignored for SRV records
}

SDConfig is the configuration for DNS based service discovery.

func (*SDConfig) Name

func (*SDConfig) Name() string

Name returns the name of the Config.

func (*SDConfig) NewDiscoverer

func (c *SDConfig) NewDiscoverer(opts discovery.DiscovererOptions) (discovery.Discoverer, error)

NewDiscoverer returns a Discoverer for the Config.

func (*SDConfig) NewDiscovererMetrics

func (*SDConfig) NewDiscovererMetrics(reg prometheus.Registerer, rmi discovery.RefreshMetricsInstantiator) discovery.DiscovererMetrics

NewDiscovererMetrics implements discovery.Config.

func (*SDConfig) UnmarshalYAML

func (c *SDConfig) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements the yaml.Unmarshaler interface.
