I'm developing a game service on ubuntu 20.04 with an unreal dedicated server on agones environment.
I'm working on adding preStop to the fleet on agones to upload logs to a fileserver when the ds is crashed.
When I directly access the pod on the EKS(AWS K8s service) environment and kill the pod with kill -15 {pid}, preStop runs correctly.
However, when I kill the pod with kill -11 {pid}, preStop does not run.
The app I'm building has a high probability of getting -11 (segmentation error).
I need preStop to fire on -11 (segmentation error) as well as -5 (sigterm).
Is it correct that preStop is not executed for segmentation error?
Thanks.
kill -15 {pid} log
