logr

contrib/logr — run Kubernetes/controller-runtime code on ubgo/logger

go-logr/logr is the logging interface used across the Kubernetes ecosystem (controller-runtime, client-go, operator-sdk, klog). This module returns a logr.Logger backed by ubgo/logger so that code runs on ubgo's engine unchanged — with structured output, redaction, sampling, and OTEL correlation.

Install

go get github.com/ubgo/logger/contrib/logr

Usage

import (
	logger "github.com/ubgo/logger"
	logrlogger "github.com/ubgo/logger/contrib/logr"
	ctrl "sigs.k8s.io/controller-runtime"
)

core := logger.New(
	logger.WithSink(logger.NewWriterSink(os.Stderr, logger.NewJSONEncoder(), logger.LevelInfo)),
)

log := logrlogger.New(core)            // logr.Logger
ctrl.SetLogger(log)                    // controller-runtime now logs via ubgo

log.WithName("reconciler").
	WithValues("pod", "nginx").
	Info("reconciling", "namespace", "default")
log.Error(err, "update failed")

V-level mapping

logr uses integer verbosity (V(n)), not named severities:

logr	ubgo level
Error(...)	LevelError
V(0).Info / Info	LevelInfo
V(1).Info	LevelDebug
V(2+).Info	LevelTrace

WithName builds a dotted logger field; WithValues binds inherited fields.
