ks-jenkins 的pod启动不了报CrashLoopBackOff

KubeSphere安装 DevOps 系统，ks-jenkins 的pod启动不了报CrashLoopBackOff，删除后还是这样，查看log日志，报错信息如下，不知道如何解决

[root@k8s-node1 ~]# kubectl logs -n kubesphere-devops-system ks-jenkins-55c6dbdbc-r4ndn

问题已经解决了，jenkins镜像版本升级到最新OK

这里说明一下我的kuberShpere版本是2.2.1的。我是在win10系统用virtualbox虚拟机装的k8s集群。

具体解决方法如下：

1.拉取最新jenkins镜像

docker pull jenkins/jenkins

最新版本有721MB

DevOps自动拉取的版本2.176.2是567MB

2‘’拉取最新镜像后修改tag，将最新的镜像tag修改为2.176.2

3、删除 ks-jenkins的pod重新启动pod，OK！

这里有一个疑问，官方提供的版本为什么我的不行。
