kubectl describe pod shows the last container state as Terminated with reason OOMKilled and exit code 137. What happened?

• The container exceeded its memory limit and the kernel killed it
• The container exceeded its CPU limit and was terminated by the scheduler
• The liveness probe failed too many times, so the kubelet restarted it
• The node ran out of disk space and evicted the Pod
