Variables

var KBLog logr.Logger

KBLog is a base parent logger.

var Log = NewDelegatingLogger(NullLogger{})

Log is the base logger used by kubebuilder. It delegates to another logr.Logger. You *must* call SetLogger to get any actual logging.

Functions

func SetLogger

func SetLogger(l logr.Logger)

SetLogger sets a concrete logging implementation for all deferred Loggers.

func ZapLogger

func ZapLogger(development bool) logr.Logger

ZapLogger is a Logger implementation. If development is true, a Zap development config will be used (stacktraces on warnings, no sampling), otherwise a Zap production config will be used (stacktraces on errors, sampling).

func ZapLoggerTo

func ZapLoggerTo(destWriter io.Writer, development bool) logr.Logger

ZapLoggerTo returns a new Logger implementation using Zap which logs to the given destination, instead of stderr. It otherise behaves like ZapLogger.

Types

type DelegatingLogger

type DelegatingLogger struct {
	logr.Logger
	// contains filtered or unexported fields
}

DelegatingLogger is a logr.Logger that delegates to another logr.Logger. If the underlying promise is not nil, it registers calls to sub-loggers with the logging factory to be populated later, and returns a new delegating logger. It expects to have *some* logr.Logger set at all times (generally a no-op logger before the promises are fulfilled).

func NewDelegatingLogger

func NewDelegatingLogger(initial logr.Logger) *DelegatingLogger

NewDelegatingLogger constructs a new DelegatingLogger which uses the given logger before it's promise is fulfilled.

func (*DelegatingLogger) Fulfill

func (l *DelegatingLogger) Fulfill(actual logr.Logger)

Fulfill switches the logger over to use the actual logger provided, instead of the temporary initial one, if this method has not been previously called.

func (*DelegatingLogger) WithName

func (l *DelegatingLogger) WithName(name string) logr.Logger

WithName provides a new Logger with the name appended

func (*DelegatingLogger) WithValues

func (l *DelegatingLogger) WithValues(tags ...interface{}) logr.Logger

WithValues provides a new Logger with the tags appended

type NullLogger

type NullLogger struct{}

NullLogger is a logr.Logger that does nothing.

func (NullLogger) Enabled

func (NullLogger) Enabled() bool

Enabled implements logr.InfoLogger

func (NullLogger) Error

func (NullLogger) Error(_ error, _ string, _ ...interface{})

Error implements logr.Logger

func (NullLogger) Info

func (NullLogger) Info(_ string, _ ...interface{})

Info implements logr.InfoLogger

func (NullLogger) V

func (log NullLogger) V(_ int) logr.InfoLogger

V implements logr.Logger

func (NullLogger) WithName

func (log NullLogger) WithName(_ string) logr.Logger

WithName implements logr.Logger

func (NullLogger) WithValues

func (log NullLogger) WithValues(_ ...interface{}) logr.Logger

WithValues implements logr.Logger
