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 ...interface{}) 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!")
