kubebuilder使用

package main
import (
    "fmt"
    ctrl "sigs.k8s.io/controller-runtime"
    "sigs.k8s.io/controller-runtime/pkg/log/zap"
)
func main() {
    ctrl.SetLogger(zap.New(zap.UseDevMode(true)))
    logger := ctrl.Log.WithName("log name").WithName("a").WithValues("a key", "a value")
    logger.Info("log msg", "b key", "b value")
    logger.Error(fmt.Errorf("log error"), "c key", "c value")
}

当使用dev模式时：

2020-05-13T08:36:10.875+0800    INFO    log name.a      log msg {"a key": "a value", "b key": "b value"}
