查找Minikube杀死pods的原因

Question

我在本地机器上的Virtual Box上创建了一个Minikube实例。我有几个复制控制器，为它们指定了资源限制。首先，我为每个复制控制器A和B创建一个实例。然后，我将rc B的复制计数增加到6。一旦将其向上扩展，我就可以看到由rc A创建的Pod被Kubernetes杀死。我只能在kubeclt日志中看到

/opt/app-server/bin/app-server.sh: line 159:    28 Killed                  $JAVA_HOME/bin/java -server $JVM_OPTS $XDEBUG $SERVER_OPTS -Djava.endorsed.dirs=$SERVER_ENDORSED -classpath $SERVER_CLASSPATH org.adroitlogic.appserver.AppServer

我不知道是什么原因导致了这个吊舱的驱逐。我猜这与pod的资源分配和VM上的有限资源有关。但我需要确认一下。该实例被驱逐的原因日志在哪里？我在journalctl -u上搜索了一下

kubectl describe pod提供了以下事件

但以上这些都没有给我一个关于原因和为什么会发生这种情况的提示。有什么建议吗？
