type Resources specs.LinuxResources

Resources defines updatable container resource values. TODO: it must match containerd upcoming API

type Stats Uses

type Stats struct {
    Read time.Time
    // Metrics is expected to be either one of:
    // *
    // *
    Metrics interface{}

Stats holds metrics properties as returned by containerd

func InterfaceToStats Uses

func InterfaceToStats(read time.Time, v interface{}) *Stats
