设置了运行带有FTP应用程序的Kubernetes服务之后,该应用程序在AKS中具有端口映射21,我注意到端口21正在通过某种过程进行探测。从我的FTP应用程序中记录了以下内容:

[I 2019-12-06 23:38:56] 10.244.0.1:56287-[] FTP session closed (disconnect).
[I 2019-12-06 23:38:56] 10.244.0.1:56330-[] FTP session opened (connect)
[I 2019-12-06 23:39:02] 10.244.0.1:56330-[] FTP session closed (disconnect).
[I 2019-12-06 23:39:02] 10.244.0.1:56376-[] FTP session opened (connect)
  • 此Pod所在的VM的IP范围为 10.244.0.0/24

  • 没有容器见解或其他任何配置

  • 我不认为这是“就绪”或“活跃度”探针,因为我已经覆盖了这些探针-但是它看起来确实很像某种通用TCP探针,可以在端口映射中配置任何端口? p>

  • 所有吊舱的完整转储给出

我肯定在这里缺少明显的东西。每6秒会不断轮询我的应用程序什么?在IP范围为10.244.0.0/24的节点上,在10.244.0.1上创建的东西是什么?

如果您具有映射到此容器的类型LoadBalancer的服务-这将是Azure负载平衡器探针进行运行状况检查以确定该服务是否仍在运行。
