kubernetes - 当它们只是信息时，日志显示为错误

Question

当我查看容器引擎日志时，我看到了很多警告。在进一步挖掘之后，我意识到这些错误实际上只是来自 heapster 的日志。

我相信这是由于日志开始于I0730

我的 kubernetes 集群正在使用版本：1.3.2

我的最新日志

Answer 1

That's because Heapster is logging to stderr rather than stdout. Starting in Kubernetes 1.3, logs written to stdout got tagged with the INFO severity and logs written to stderr got tagged with the ERROR severity.

That clearly isn't working well for Heapster since it's sending all of its logs to stderr. I've opened up https://github.com/kubernetes/kubernetes/issues/29862 to track improving this.
