kubernetes - GKE指标服务器生成错误-flag.Parse:E0907

Question

在GKE中创建了新集群，并在日志中看到错误:
“错误:在标志之前记录日志。解析:E0907 16:33:58.813216 1 nanny_lib.go:128]获取https://10.0.0.1:443/api/v1/nodes?resourceVersion=0:http2:没有缓存的连接可用
”

我尝试找到有关如何解决此错误的解决方案。
主版本:1.16.13-gke.1
GKE的云运营:系统和工作负载日志记录和监控

我已经使用以下版本的帐户测试了自己的帐户:1.16.13-gke.1，1.16.13-gke.400和1.17.9-gke1503，并收到了类似的错误，但并不相同:

$ kubectl logs metrics-server-v0.3.6-547dc87f5f-jrnjt -c metrics-server-nanny -n kube-system

由于我尚未在集群中部署任何东西，因此在我看来，GKE中默认启用的系统和工作负载日志记录与监视插件中存在一些问题。
我的建议是在 GCP Issue tracker中公开票务公开问题，因为这些容器由GKE管理。
