Types

type Dialer

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

func NewRegionInstanceGroupDialer

func NewRegionInstanceGroupDialer(project, region, group string) *Dialer

NewRegionInstanceGroupDialer returns a new dialer that dials named regional instance group in the provided project and region.

It begins polling immediately, and there's no way to stop it. (Until we need one)

func (*Dialer) PickIP

func (d *Dialer) PickIP(ctx context.Context) (ip string, err error)

PickIP returns a randomly healthy IP, waiting until one is available, or until ctx expires.
