2. etcdserver: Fix txn request 'took too long' warnings to use loggable request stringer
etcdのアップグレード後(3.1.7->3.3.3.7):systemctl status etcd-lサービスステータスを表示します.次のエラーがありますが、kubernetesの正常な動作には影響しません.
解決参考(次のバージョンで3.3.3.8にアップグレードしてもこのエラーメッセージがあります):https://github.com/coreos/etcd/pull/9835
3. istio-sidecar-injector.istio-system.svc:443 Client.Timeout
istioを0.8.0にアップグレードすると、sidecarを自動的に埋め込むことはできません.
このケースに引き続きフォローします.https://github.com/istio/old_issues_repo/issues/271
