Types

type Discovery

type Discovery struct {
	// 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) *Discovery

NewDiscovery returns a new Discovery which periodically refreshes its targets.

func (*Discovery) Run

func (d *Discovery) Run(ctx context.Context, ch chan<- []*targetgroup.Group)

Run implements the Discoverer interface.

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
	// Catches all undefined fields and must be empty after parsing.
	XXX map[string]interface{} `yaml:",inline"`
}

SDConfig is the configuration for DNS based service discovery.

func (*SDConfig) UnmarshalYAML

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

UnmarshalYAML implements the yaml.Unmarshaler interface.
