Jenkins POD重启如何持久化Jenkins配置和插件

Question

我已经将我的Jenkins部署为kubernetes yaml文件的一部分，并且还启用了Persist volume claim，当我的Jenkins pod重新启动时，我丢失了所有的作业和配置，这意味着我需要重新安装所有的Jenkins建议插件，配置kubernetes云，配置git repo，并创建新的管道作业。

云，请告诉我如何避免上述情况。

vi jenkins-deployment.yaml

kubectl get pvc -n jenkins

请告诉我是否需要我这边的任何细节

Answer 1

请从volumeMounts中删除subpath，因为子路径将覆盖/var目录下的所有内容。所以应该是这样的

volumeMounts:
- mountPath: /var
name: jenkins-home
