klog-gokit

This packages is a replacement for klog in projects that use the go-kit logger.

It is heavily inspired by the github.com/kubermatic/glog-gokit package.

Usage

Override the official klog package with this one. This simply replaces the code in vendor/k8s.io/klog with the code of this package.

With dep

In your Gopkg.toml:

[[override]]
  name = "k8s.io/klog"
  source = "github.com/simonpasquier/klog-gokit"

With Go modules

Add this line to your go.mod file:

replace k8s.io/klog => github.com/kubermatic/klog-gokit master

In your main.go:

// Import the package like it is original klog
import "k8s.io/klog"


// Create go-kit logger in your main.go
logger := log.NewLogfmtLogger(log.NewSyncWriter(os.Stdout))
logger = log.With(logger, "ts", log.DefaultTimestampUTC)
logger = log.With(logger, "caller", log.DefaultCaller)
logger = level.NewFilter(logger, level.AllowAll())

// Overriding the default klog with our go-kit klog implementation.
// Thus we need to pass it our go-kit logger object.
klog.SetLogger(logger)

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