the default namespace has a limitrange that sets cpu=100m which you can work around by setting your own limits of cpu=10m, that'd given you more pods per node and (probably) a faster repro

Sets eviction-hard to memory.available<30%, so memory threshold triggers easily without invoking OOM killer.
Creates deployment with pods that consume memory (which is enough to trigger the threshold).
Deletes all pods every 5 seconds, to constantly retrigger memory threshold.
It can be a good sanity check to make sure that the threshold is being triggered
to see if threshold is being triggered: cat /var/log/kubelet.log | grep "eviction: threshold crossed"
