If a pod has ephemeral storage limits, the kubelet should be able to cause an eviction, regardless of lifecycle handlers which might be running.
Currently, a pod with a long-running postStart handler is never terminated even if evicted.
Example pod:
apiVersion: v1
kind: Pod
metadata:
name: test2
spec:
containers:
- name: test
image: busybox
command:
- /bin/sh
args:
- -c
- |-
_term() {
echo "Caught SIGTERM signal!"
}
trap _term SIGTERM
while true; do
dd if=/dev/zero of=/tmp/zero bs=1M count=20 oflag=append conv=notrunc
sleep 3600
done
resources:
limits:
cpu: "100m"
memory: "50Mi"
ephemeral-storage: "10Mi"
