Question

我们开始监视我们的k8s集群中的docker事件，并注意到在短时间内各种容器中有Kill/Die/Stop/Destroy个容器。

那正常吗？（我认为不是）

显然不是容量问题：

所有豆荚显示状态为“正在运行”

有关进一步调试的任何提示？

Answer 1

您可以在运行Pod的节点主机上按以下命令检查docker容器的状态。

docker inspect <container id>

更多选项为here

事件日志和日志日志有助于调试。

kubectl get events

journalctl --no-pager

在短时间内杀死/重启容器是正常的docker daemon吗？
