When executing a reboot/shutdown
k8s pods are not receiving the SIGTERM
signal which leads some of them to
unexpected behaviour such as generating
huge coredumps.
There is an upstream issue regarding this:
https://github.com/kubernetes/kubernetes/issues/107158
The problem seems to be systemd related
but this commit addresses the problem
with a workaround.
This commit introduces a new script that
will cleanup all the remaing pods and will
be run after kubelet is stopped.
The script is executed successfully when
kubelet stops and the pods are stopped
before the system shuts down.
