问题描述

从昨天开始，我开始遇到jenkins pod的问题-无法初始化.同时，我还没有更新任何配置.

我试图对其进行编辑并设置特定的詹金斯图像版本，例如image: jenkins/jenkins:2.219，但是它仍然无法初始化.

I have tried to edit it and set the specific jenkins image version, for example image: jenkins/jenkins:2.219, but it is still not able to initialize.

当我运行kubectl logs jenkins-df87c46d5-52dtt -c copy-default-config -n infrastructure时，我可以看到以下日志:

When I run kubectl logs jenkins-df87c46d5-52dtt -c copy-default-config -n infrastructure I can see the following log:

推荐答案

尝试一下.我已经删除了可能导致该问题的插件目录

Try this. I have removed the plugin directiory which might cause the issue
