Functions

func NewGRPCRunner

func NewGRPCRunner(srv *grpc.Server, sockFile string, leaderElection bool) manager.Runnable

NewGRPCRunner creates controller-runtime's manager.Runnable for a gRPC server. The server will listen on UNIX domain socket at sockFile. If leaderElection is true, the server will run only when it is elected as leader.

func NewMetricsExporter

func NewMetricsExporter(nodeName string, volume volume.LocalVolume) manager.Runnable

NewMetricsExporter creates controller-runtime's manager.Runnable to run a metrics exporter for a node.

Types

type Checker

type Checker interface {
	manager.Runnable
	Ready() (bool, error)
}

Checker is the interface to check plugin readiness.

func NewChecker

func NewChecker(check func() error, interval time.Duration) Checker

NewChecker creates controller-runtime's manager.Runnable to run health check function periodically at given interval.

type DeviceMetrics struct {
	FreeBytes   uint64
	TotalBytes  uint64
	DeviceGroup string
}

Device Metrics

type VolumeMetrics

type VolumeMetrics struct {
	Volume     string
	TotalBytes uint64
	UsedBytes  float64
}
