是否可以在运行时更新 zap 记录器的日志级别？

我创建了一个记录器kubebuilder，它基于 zap 记录器：

import (
    "flag"
    "github.com/gin-gonic/gin"
    "net/http"
    "os"
    "go.uber.org/zap/zapcore"
    uzap "go.uber.org/zap"
    // Import all Kubernetes client auth plugins (e.g. Azure, GCP, OIDC, etc.)
    // to ensure that exec-entrypoint and run can make use of them.
    _ "k8s.io/client-go/plugin/pkg/client/auth"

    "k8s.io/apimachinery/pkg/runtime"
    utilruntime "k8s.io/apimachinery/pkg/util/runtime"
    clientgoscheme "k8s.io/client-go/kubernetes/scheme"
    ctrl "sigs.k8s.io/controller-runtime"
    "sigs.k8s.io/controller-runtime/pkg/healthz"
    "sigs.k8s.io/controller-runtime/pkg/log/zap"

)

var (
    scheme   = runtime.NewScheme()
    setupLog = ctrl.Log.WithName("setup")
)

var zapOpts []uzap.Option
    zapOpts = append(zapOpts, uzap.AddCaller())
    zapOpts = append(zapOpts, uzap.AddCallerSkip(1))
    zapOpts = append(zapOpts, uzap.AddStacktrace(uzap.DebugLevel))

    opts := zap.Options{
        Development:     developmentFlag,
        StacktraceLevel: stacktraceLevel,
        Level:           level,
        Encoder:         encoder,
        ZapOpts:  zapOpts,
    }

    opts.BindFlags(flag.CommandLine)
    flag.Parse()

    ctrl.SetLogger(zap.New(zap.UseFlagOptions(&opts)))

现在我想将日志级别更改为zapcore.InfoLevel在运行时。我没有找到任何SetLogLevel或类似的API。

我需要创建新选项然后设置新级别吗？

我还需要设置记录器sigs.k8s.io/controller-runtime/pkg/log/zap图书馆。记录器的接口来自go-logr它实现了logr.Logger界面。如果我尝试将其更改为zapcore.NewCore我无法设置记录器ctrl.SetLogger不再了。

我想保留更新所有选项的选项zap.Options并且还要更改日志级别，并且仍然使用 zapsigs.k8s.io/controller-runtime/pkg/log/zap.

是否可以这样做sigs.k8s.io/controller-runtime/pkg/log/zap and sigs.k8s.io/controller-runtime?

Yes 有可能的 using AtomicLevel。来自文档：

atom := zap.NewAtomicLevel()

// To keep the example deterministic, disable timestamps in the output.
encoderCfg := zap.NewProductionEncoderConfig()
encoderCfg.TimeKey = ""

logger := zap.New(zapcore.NewCore(
    zapcore.NewJSONEncoder(encoderCfg),
    zapcore.Lock(os.Stdout),
    atom,
))
defer logger.Sync()

logger.Info("info logging enabled")
atom.SetLevel(zap.ErrorLevel)
logger.Info("info logging disabled")
