Types

type Service

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

Service contains necessary data for service discovery in GKE.

func MustNewService

func MustNewService(project string) *Service

MustNewService creates a new GKE service discovery instance. The function exits if an error occurs during setup.

func (*Service) Discover

func (s *Service) Discover(ctx context.Context) ([]discovery.StaticConfig, error)

Discover uses the Compute Engine, Container Engine, and Kubernetes APIs to check every GCE zone for Container Engine (gke) clusters, and checks each cluster for services annotated for federated scraping.

Collect returns every gke cluster with a k8s service annotation that equals:

gke-prometheus-federation/scrape: true
