KubeSphere版本信息
v3.1.1。在已有K8s上离线安装。

问题如下

使用了一段时间的KS之后，需要开启devops，按照文档https://v3-1.docs.kubesphere.io/zh/docs/pluggable-components/devops/ 中的“在安装后启用DevOps”的教程开启了DevOps

ClusterConfiguration如下：

命令行查看ks-install安装日志如下：

但是从KS的UI看到DevOps组件异常

排查过程如下：

1.查看了异常的pod `ks-jenkins-6f9df7f59b-n6xnf`

结果如下：

存活探针和就绪探针均失败

2.以下是所有pod中异常的pod

这个recycler-for-pv0-nfs 是因为volume挂载失败显示的异常，可以忽略

3.查看helm安装的组件

发现没有安装UC组件，不知道是否正常
