用docker compose安装zookeeper后无端口

Question

我使用了docker-compose安装zookeeper伪集群，安装完后无法启动zookeeper，显示无Client Point

version: '3.7'
services:
    zoo1:
        image: zookeeper
        restart: always
        hostname: zoo1
        ports:
            - 2181:2181
        environment:
            ZOO_MY_ID: 1
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

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

    zoo3:
        image: zookeeper
        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=zoo3:2888:3888

zookeeper状态为：

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.

请教下这是什么情况？

参见官网提示 zk3.5以后的集群配置格式有变化

https://hub.docker.com/_/zook...
This will start Zookeeper 3.5 in replicated mode. Please note, that Zookeeper 3.4 has slightly different ZOO_SERVERS format. Run docker stack deploy -c stack.yml zookeeper(or docker-compose -f stack.yml up) and wait for it to initialize completely. Ports 2181-2183 will be exposed.

Please be aware that setting up multiple servers on a single machine will not create any redundancy. If something were to happen which caused the machine to die, all of the zookeeper servers would be offline. Full redundancy requires that each server have its own machine. It must be a completely separate physical server. Multiple virtual machines on the same physical host are still vulnerable to the complete failure of that host.

Consider using Docker Swarm when running Zookeeper in replicated mode.
