我一直在使用JDK 11映像在Kubernetes上运行一个Spring Boot 应用程序。我的预期是，当JVM遇到内存不足异常时，pod应该被杀死，以便Kubernetes可以启动一个更大的pod。我可以确认这不是正在发生的事情。我不确定是否有一些我必须设置的JVM参数丢失了，或者可能有一些Kubernetes配置需要注意这种情况。
我使用了以下JVM参数：

-XX:InitialRAMPercentage=20.0 -XX:MinRAMPercentage=50.0 -XX:MaxRAMPercentage=80.0 -XX:+HeapDumpOnOutOfMemoryError -XX:+ExitOnOutofMemoryError

抛出的异常：

我认为发生的情况是OOM异常导致pod关闭，然后在尝试关闭pod时抛出了相同的异常。因此，我尝试通过添加-XX:OnOutOfMemoryError="kill -9 %p来杀死pod，但没有帮助。
稍微不同的是，pod内存限制为2Gi。但是，pod在大约700Mi时出现OOM异常，所以我不认为内存不足，只是pod在尝试扩展内存之前抛出了异常：

resources:
      limits:
        cpu: "1"
        memory: 2Gi
      requests:
        cpu: 10m
        memory: 128Mi

我还测试了-XX:+CrashOnOutOfMemoryError，它没有帮助解决我的情况和吊舱不断抛出OOM的尝试关闭容器。
