由于系统中打开的文件太多，Kubernetes无法启动 [英] Kubernetes can't start due to too many open files in system

问题描述

我正在尝试使用Kubernetes创建一堆pod，服务和部署，但是当我运行 kubectl描述命令时，会继续遇到以下错误。

I am trying create a bunch of pods, services and deployment using Kubernetes, but keep hitting the following errors when I run the kubectl describe command.

对于POD与RunContainerError：runContainer：API错误（500）：无法启动容器bbdb58770a848733bf7130b1b230d809fcec3062b2b16748c5e4a8b12cc0533a：[8]系统错误：系统中打开的文件太多\\ n

我已经终止了所有的pod，并尝试重新启动机器，但它并不能解决问题。我不是Linux专家，所以我只是想知道如何找到所有打开的文件并关闭它们？

I have already terminated all pods and try restarting the machine, but it doesn't solve the issue. I am not an Linux expert, so I am just wondering how shall find all the open files and close them?

推荐答案

你可以确认哪个进程正在通过运行文件描述符：

You can confirm which process is hogging file descriptors by running:

lsof | awk '{print $2}' | sort | uniq -c | sort -n

这将给你一个打开的FD计数的排序列表与进程的pid。然后你可以查找每个进程w /

That will give you a sorted list of open FD counts with the pid of the process. Then you can look up each process w/

ps -p <pid>

如果主要的猪是docker / kubernetes，那么我建议在问题，caesarxuchao引用。

If the main hogs are docker/kubernetes, then I would recommend following along on the issue that caesarxuchao referenced.
