Running a stakepool on kubernetes

Hi there :wave:
Is there someone experienced in Running a Stakepool on a Kubernetes Cluster?
I created this helm Template as a base for a cardano node but my issue is that the pods are always restarting and then result in a CrashLoopBackof status with log errors like this

on: SubscriberError {seType = SubscriberWorkerCancelled, seMessage = "SubscriptionWorker exiting", seStack = []}

Is there something which i need to consider with kubernetes and a cardano node?
I already increased failureThreshold and initialDelaySeconds but this did not help a lot.

thank you already in advance for your help.
