Documentation

Overview

Package util groups a bunch of common helper functions used by commands.

Index

• Variables
• func Errorf(format string, args ...any) subcommands.ExitStatus
• func Fatalf(format string, args ...any)
• func Infof(format string, args ...any)
• type Writer
  • func (i *Writer) Write(data []byte) (n int, err error)

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.

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.
