Strange port issue when using 3.5 with docker-compose

[aiqingyuyan]

Not sure if it's just my problem or not. I am using the provided docker-compose.yml example in the documentation. When I started on local, all 3 containers started up, but when I went into containers themselves and ran ./zkServer.sh status, all of them gave me the following output:

ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
Client port not found in static config file. Looking in dynamic config file.
grep: : No such file or directory
Client port not found. Terminating.

zookeeper cannot start

But then when I switch zookeeper version to 3.4, everything works perfectly, zookeeper starts correctly, I can connect to each of the node using zkCli.sh

Expected behavior

Using the provided docker-compose.yml example with zookeeper:3.5 on local, zookeeper should start correctly, no port issue

Actual behavior

Cannot find port

Steps to reproduce the behavior

1. Using the following compose file

version: '3.1'

services:
  zoo1:
    image: zookeeper:3.5
    restart: always
    hostname: zoo1
    ports:
      - 2181:2181
    environment:
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=0.0.0.0:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

  zoo2:
    image: zookeeper:3.5
    restart: always
    hostname: zoo2
    ports:
      - 2182:2181
    environment:
      ZOO_MY_ID: 2
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=0.0.0.0:2888:3888 server.3=zoo3:2888:3888

  zoo3:
    image: zookeeper:3.5
    restart: always
    hostname: zoo3
    ports:
      - 2183:2181
    environment:
      ZOO_MY_ID: 3
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=0.0.0.0:2888:3888

and run docker-compose up -d

2. Go into any of the containers, then cd to bin folder, and ran ./zkServer.sh status

HI all.
I have same issue.

8:/apache-zookeeper-3.5.5-bin# cat /conf/zoo.cfg
dataDir=/data
dataLogDir=/datalog
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
standaloneEnabled=true
server.1=zoo1:2888:3888
server.2=0.0.0.0:2888:3888
server.3=zoo3:2888:3888

Without clientPort=2181

Hello guys and thanks for reporting this! 👍

The issue is that the client port part is missing in ZOO_SERVERS. E.g., for zoo1 it should have been ZOO_SERVERS: server.1=0.0.0.0:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181.

I updated the stack.yml example accordingly.
