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 describe 命令时不断遇到以下错误.
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.
for "POD" with RunContainerError: "runContainer: API error (500): Cannot start container bbdb58770a848733bf7130b1b230d809fcec3062b2b16748c5e4a8b12cc0533a: [8] System error: too many open files in system"
for "POD" with RunContainerError: "runContainer: API error (500): Cannot start container bbdb58770a848733bf7130b1b230d809fcec3062b2b16748c5e4a8b12cc0533a: [8] System error: too many open files in system"
我已经终止了所有 pod 并尝试重新启动机器，但这并没有解决问题.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
你可以通过运行来确认是哪个进程占用了文件描述符:
You can confirm which process is hogging file descriptors by running:
lsof | awk '{print $2}' | sort | uniq -c | sort -n
这将为您提供带有进程 pid 的打开 FD 计数的排序列表.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，那么我建议按照 caesarxuchao 引用的问题.
If the main hogs are docker/kubernetes, then I would recommend following along on the issue that caesarxuchao referenced.
