Types

type Discovery

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

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

func NewDiscovery

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

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 {
	// Project: The Google Cloud Project ID
	Project string `yaml:"project"`

	// Zone: The zone of the scrape targets.
	// If you need to configure multiple zones use multiple gce_sd_configs
	Zone string `yaml:"zone"`

	// Filter: Can be used optionally to filter the instance list by other criteria.
	// Syntax of this filter string is described here in the filter query parameter section:
	// https://cloud.google.com/compute/docs/reference/latest/instances/list
	Filter string `yaml:"filter,omitempty"`

	RefreshInterval model.Duration `yaml:"refresh_interval,omitempty"`
	Port            int            `yaml:"port"`
	TagSeparator    string         `yaml:"tag_separator,omitempty"`

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

SDConfig is the configuration for GCE based service discovery.

func (*SDConfig) UnmarshalYAML

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

UnmarshalYAML implements the yaml.Unmarshaler interface.
