我已经安装了Anaconda和jupyterhub。当我在centOS7上启动jupyterhub时。通过Active Directory对Linux机器进行身份验证。它可以正常启动，但是user123（是活动目录用户）尝试登录，无法生成服务器。这是我在日志中看到的：

请让我知道我想念什么？

检查用户映像/pod 的事件日志，例如，如果您已使用 admin 用户登录，则 jupyter-admin 命名的 pod 必须存在于您的集群中。
运行kubectl get pods <user-po-name> -n <jhub-namespace>
现在，检查事件部分，
由于没有生成哪个容器，它会显示错误。
拉图像或 postHook 一定是问题。
还需要添加信息，例如您的 config.yaml、jhub 版本等。

我在Linux机器上遇到了同样的错误，并通过释放系统上的一些内存来摆脱了这个错误。
我认为TimeoutError只是由于系统响应缓慢而导致的30秒常规超时。填充系统RAM的某些过程导致其开始交换。要检查内存使用情况：
free -h
然后
htop -s PERCENT_MEM
找出什么进程正在消耗内存。
