# klog-gokit
|
|
|
|
This packages is a replacement for [klog](https://github.com/kubernetes/klog)
|
|
in projects that use the [go-kit logger](https://godoc.org/github.com/go-kit/kit/log).
|
|
|
|
It is heavily inspired by the [`github.com/kubermatic/glog-gokit`](https://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`:
|
|
```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`:
|
|
```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.
