facing the same problem, but I think the reason is the entrypoint.sh of zk
docker images did not parse the ZOO_PORT parameter, so the zoo.cfg will not
have a clientPort to start. I changed the compose.yaml and it works for me now.
```
version: '3.7'
services:
zookeeper:
image: zookeeper
container_name: COMPANY-zookeeper
restart: unless-stopped
hostname: zookeeper
ports:
- "2181:2181"
environment:
ZOO_SERVERS: server.1=zookeeper:2888:3888;2181
volumes:
- ../.env/zookeeper_data:/var/lib/zookeeper/data
- ../.env/zookeeper_txn_logs:/var/lib/zookeeper/log
```

[jira] [Commented] (ZOOKEEPER-4238) NullPointerException in ContainerManager is still a thing

It seems we lost the null checker added in ZOOKEEPER-2464.
[~johanforssell] go ahead if you already have a patch. Otherwise I'd like to
throw a pr in hours so that you can verify it.
