Rancher Server 设置
- Rancher 版本：2.7.6
- 安装选项 (Docker install/Helm Chart): Helm Chart安装，Local集群为k3s v1.26.5+k3s1
- 如果是 Helm Chart 安装，需要提供 Local 集群的类型（RKE1, RKE2, k3s, EKS, 等）和版本：
- 在线或离线部署：在线部署
下游集群信息
- Kubernetes 版本: k8s-v1.25.3
- Cluster Type (Local/Downstream):
- 如果 Downstream，是什么类型的集群?(自定义/导入或为托管 等): 导入
用户信息
- 登录用户的角色是什么？ （管理员/集群所有者/集群成员/项目所有者/项目成员/自定义）：管理员
- 如果自定义，自定义权限集：
主机操作系统：
Ubuntu22.04
问题描述：
rancher版本从2.7.5升级至2.7.6之后，下游集群的fleet-agent的pod启动失败并带有日志报错，但local集群的fleet-agent服务是启动正常没有任何报错，local集群和下游进去均未开启使用fleet功能。
重现步骤：
期间重启过local集群的fleet-agent的pod一直是正常的，但重启下游集群的fleet-agent的pod还是同样的报错，容器启动后过2到3分钟直接报错。
结果：
下游集群的fleet-agent服务pod运行2到3分钟后直接报错并自动重启。
预期结果：
fleet-agent应该是正常启动并无报错并无自动重启。
