------------------------------------

Discussed with [~david.mao] offline and he said he would not have time to do this soon, so we agreed I could pick it up.

>             Project: Kafka
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 2.3.0
>         Environment: Linux, Docker 19.03.4

> We are using Kafka and Zookeeper in Docker swarm stacks. When we undeploy a stack, sometimes Kafka doesn't shutdown properly and is finally killed by Docker (thus leaving potentially corrupted files).
> Here are the steps to reproduce (simple Docker, no swarm):
>  
> {code:java}
> docker network create test
> docker run -d --network test --name zk --rm zookeeper:3.5.6
> docker run --network test --name kf --rm -e "KAFKA_ZOOKEEPER_CONNECT=zk:2181" -e "KAFKA_ADVERTISED_LISTENERS=INSIDE://:9091" -e "KAFKA_LISTENER_SECURITY_PROTOCOL_MAP=INSIDE:PLAINTEXT" -e "KAFKA_INTER_BROKER_LISTENER_NAME=INSIDE" confluentinc/cp-kafka:5.3.1
> {code}
>  
> In another shell:
>  
> {code:java}
> docker stop zk
> docker stop kf
> {code}
>
