kubernetes - stackdriver-metadata-agent-cluster级别由于[2a00:1450:400c:c09::5f]:443导致很多失败:I/O超时

Question

我在Europe-west1-d区域中拥有 1.14.10-gke.27 的 k8s 。

在过去的几天里，我在kube-system ns中有很多stackdriver-metadata-agent-cluster-level pod重新启动，但有错误

这是Google网路问题吗？

我将其添加为答案，因为如果我在注释中添加了很多代码，它们将完全不可读。一旦我们设法找出解决方案，我将对其进行编辑。

您能否运行这些 Stackdriver日志查询，并将输出作为代码示例发布到您的问题中(在所选文本上使用ctrl + k)？
