why I cannot see the logs in k8s klog via kubectl logs?
问题
我在k8s中看到了一些源代码：
// 立即删除，或者不支持优雅删除klog.V(6).Infof("going to delete %s from registry: ", name)
if _, _, err := e.Delete(ctx, accessor.GetName(), deleteValidation, options); err != nil && !apierrors.IsNotFound(err) {klog.V(4).Infof("Delete %s in DeleteCollection failed: %v", accessor.GetName(), err)errs <- errreturn}
我认为我可以通过 kubectl logs 来检查这些日志，但是我无法看到它们，即使使用 kubectl logs --v 6 <kubeapi server pod> | grep "going to delete" 或者 kubectl logs --v 4 <kubeapi server pod> | grep "DeleteCollection"，我仍然无法看到应该由 klog 输出的日志。我该如何检查这些日志？

I saw some source codes in k8s:
// delete immediately, or no graceful deletion supportedklog.V(6).Infof("going to delete %s from registry: ", name)
if _, _, err := e.Delete(ctx, accessor.GetName(), deleteValidation, options); err != nil && !apierrors.IsNotFound(err) {klog.V(4).Infof("Delete %s in DeleteCollection failed: %v", accessor.GetName(), err)errs <- errreturn}
I think I can check these logs via kubectl logs, but I cannot see them, even use kubectl logs --v 6 <kubeapi server pod> | grep "going to delete" or kubectl logs --v 4 <kubeapi server pod> | grep "DeleteCollection" I still cannot see the logs that should be output by klog.
How can I check these logs?

答案是：
将--v=4参数添加到kube api server配置文件中以启用日志详细程度。
文件路径：/etc/kubernetes/manifests/kube-apiserver.yaml
apiVersion: v1kind: Podmetadata:annotations:kubeadm.kubernetes.io/kube-apiserver.advertise-address.endpoint: 192.168.49.2:8443creationTimestamp: nulllabels:component: kube-apiservertier: control-planename: kube-apiservernamespace: kube-systemspec:containers:- command:- kube-apiserver- --advertise-address=192.168.49.2- --allow-privileged=true- --v=4.......
然后运行kubectl log --v=4命令。

The answer is:
add --v=4 arg to kube api server config file to enable the log verbosity.
File path: /etc/kubernetes/manifests/kube-apiserver.yaml
apiVersion: v1kind: Podmetadata:annotations:kubeadm.kubernetes.io/kube-apiserver.advertise-address.endpoint: 192.168.49.2:8443creationTimestamp: nulllabels:component: kube-apiservertier: control-planename: kube-apiservernamespace: kube-systemspec:containers:- command:- kube-apiserver- --advertise-address=192.168.49.2- --allow-privileged=true- --v=4.......
then kubectl log --v=4
