【问题描述】：

我已将我的 Jenkins 部署为 kubernetes yaml 文件的一部分，并且还启用了 Persist 卷声明，当我的 Jenkins pod 重新启动时，我失去了所有工作和配置，这意味着我需要重新安装所有 Jenkins 建议插件，配置Kubernetes 云，配置 git repo，并创建新的管道作业。

云请帮我如何避免上述情况。

      volumes:
      - name: jenkins-home
        persistentVolumeClaim:
          claimName: pvc-jenkins-home

vi jenkins-pvc.yaml

kind: PersistentVolumeClaim

 kubectl get pvc -n jenkins

如果我需要任何详细信息，请告诉我

【参考方案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
