Constants

const (
	DefaultLogFormat = "text"
	JSONLogFormat    = "json"
)

Supported klog formats

Variables

var LogRegistry = NewLogFormatRegistry()

LogRegistry is new init LogFormatRegistry struct

Functions

func AddFlags

func AddFlags(fs *pflag.FlagSet)

AddFlags registers this package's flags on arbitrary FlagSets, such that they point to the same value as the global flags.

func BindLoggingFlags

func BindLoggingFlags(c *config.LoggingConfiguration, fs *pflag.FlagSet)

BindLoggingFlags binds the Options struct fields to a flagset

func FlushLogs

func FlushLogs()

FlushLogs flushes logs immediately.

func GlogSetter

func GlogSetter(val string) (string, error)

GlogSetter is a setter to set glog level.

func InitLogs

func InitLogs()

InitLogs initializes logs the way we want for kubernetes.

func NewLogger

func NewLogger(prefix string) *log.Logger

NewLogger creates a new log.Logger which sends logs to klog.Info.

func UnsupportedLoggingFlags

func UnsupportedLoggingFlags(normalizeFunc func(name string) string) []string

UnsupportedLoggingFlags lists unsupported logging flags

func ValidateLoggingConfiguration

func ValidateLoggingConfiguration(c *config.LoggingConfiguration, fldPath *field.Path) field.ErrorList

Types

type KlogWriter

type KlogWriter struct{}

KlogWriter serves as a bridge between the standard log package and the glog package.

func (KlogWriter) Write

func (writer KlogWriter) Write(data []byte) (n int, err error)

Write implements the io.Writer interface.

type LogFormatRegistry

type LogFormatRegistry struct {
	// contains filtered or unexported fields
}

LogFormatRegistry store klog format registry

func NewLogFormatRegistry

func NewLogFormatRegistry() *LogFormatRegistry

NewLogFormatRegistry return new init LogFormatRegistry struct

func (*LogFormatRegistry) Delete

func (lfr *LogFormatRegistry) Delete(name string) error

Delete specified log format logger

func (*LogFormatRegistry) Freeze

func (lfr *LogFormatRegistry) Freeze()

func (*LogFormatRegistry) Get

func (lfr *LogFormatRegistry) Get(name string) (logr.Logger, error)

Get specified log format logger

func (*LogFormatRegistry) List

func (lfr *LogFormatRegistry) List() []string

List names of registered log formats (sorted)

func (*LogFormatRegistry) Register

func (lfr *LogFormatRegistry) Register(name string, logger logr.Logger) error

Register new log format registry to global logRegistry

func (*LogFormatRegistry) Set

func (lfr *LogFormatRegistry) Set(name string, logger logr.Logger) error

Set specified log format logger

type Options

type Options struct {
	Config config.LoggingConfiguration
}

Options has klog format parameters

func NewOptions

func NewOptions() *Options

NewOptions return new klog options

func (*Options) AddFlags

func (o *Options) AddFlags(fs *pflag.FlagSet)

AddFlags add logging-format flag

func (*Options) Apply

func (o *Options) Apply()

Apply set klog logger from LogFormat type

func (*Options) Validate

func (o *Options) Validate() []error

Validate verifies if any unsupported flag is set for non-default logging format
