kubernetes应用程序pod无法将pod emptydir卷装载共享到守护程序fluentd pod

我有一个应用程序吊舱，在那里我将日志记录到一个特定位置的文件中

我已经使用emptyDir volumeMount将此位置共享给其他pod

我在我的ELF stack-dashboard中得到了标准的stdout和stderr。如何捕获自定义日志

在这里提问之前，我已经尝试过卷主机路径、emptyDir和其他类型。我只想从守护程序访问我的应用程序日志。我可以在没有守护程序的情况下完成这项工作。

Kubernetes将把所有日志发送到节点/var/log等。fluentd daemoset需要hostPath卷来获取日志并发送到日志记录器，顾名思义，当pod被调度到一个节点时，将为空

volumes:
- name: varlog
  hostPath:
    path: /var/log
- name: varlibdockercontainers
  hostPath:
    path: /var/lib/docker/containers

查看和了解更多信息。

谢谢。我已经准备好了，现在就开始尝试。仍然不工作。您可以共享您的守护程序yaml吗？
