Variables ¶

var ErrorLogger io.Writer

ErrorLogger is where error messages should be written to. These messages are consumed by containerd and show up to users of command line tools, like docker/kubectl.

Functions ¶

func Errorf ¶

func Errorf(format string, args ...any) subcommands.ExitStatus

Errorf logs error to containerd log (--log), to stderr, and debug logs. It returns subcommands.ExitFailure for convenience with subcommand.Execute() methods:

return Errorf("Danger! Danger!")

func Fatalf ¶

func Fatalf(format string, args ...any)

Fatalf logs the same way as Errorf() does, plus *exits* the process.

func Infof ¶

func Infof(format string, args ...any)

Infof writes message to log and stdout.

func IsPCIDeviceDirTPU ¶

func IsPCIDeviceDirTPU(sysfsPath string, allowedDeviceIDs map[uint64]struct{}) bool

IsPCIDeviceDirTPU returns if the given PCI device sysfs path is a TPU device with one of the allowed device IDs.

func IsTPUDeviceValid ¶

func IsTPUDeviceValid(path string) (bool, error)

IsTPUDeviceValid returns if the accelerator device is valid.

Types ¶

type Writer ¶

type Writer struct{}

Writer writes to log and stdout.

func (*Writer) Write ¶

func (i *Writer) Write(data []byte) (n int, err error)

Write implements io.Writer.
