kubermatic / glog-logrus

glog-logrus

This packages is a replacement for glog in projects that use the logrus.

It is inspired by istio's glog package for zap: https://github.com/istio/glog

Usage

Override the official glog package with this one. This simply replaces the code in vendor/golang/glog with the code of this package.

In your Gopkg.toml:

[[override]]
  name = "github.com/golang/glog"
  source = "github.com/kubermatic/glog-logrus"

In your main.go:

// Import the package like it is original glog
import (
  "github.com/golang/glog"
  "github.com/sirupsen/logrus"
)

// Create logrus logger in your main.go
logger := logrus.New()
logger.Formatter = &logrus.JSONFormatter{DisableTimestamp: true}

// Overriding the default glog with our logrus glog implementation.
// Thus we need to pass it our logrus logger object.
glog.SetLogger(logger.WithField("foo", "bar"))

Setting the logger to the glog package MUST happen before using glog in any package.

The functionality of logging the filename and line number is not preserved at this time.
