I am running a Kafka pod in Kubernetes with Rancher. I am using the confluent image and it is connecting properly to zookeeper. I am using the stable helm chart with the Kafka confluent image 5.3.1. I also added SSL encryption into Helm using this page It is starting properly then it shutdown abruptly and pod restart. I am getting this error on the log.

[2019-11-15 19:41:49,943] INFO Terminating process due to signal SIGTERM (org.apache.kafka.common.utils.LoggingSignalHandler) [2019-11-15 19:41:49,945] INFO Shutting down SupportedServerStartable (io.confluent.support.metrics.SupportedServerStartable)

What is the SIGTERM error in Kafka pods? How to fix it?

Thank you
