Docker的Zookeeper群集模式出错？

我正在尝试在不同的主机上使用docker部署zookeeper集群。我使用下一个docker compose，其中我在host1中运行zoo1，在host2中运行zoo2，在host3中运行zoo3

version: '2'
services:
    zoo1:
        image: 31z4/zookeeper
        restart: always
        ports:
            - 2181:2181
            - 2888:2888
            - 3888:3888
        environment:
            ZOO_MY_ID: 1
            ZOO_SERVERS: server.1=host1-IP:2888:3888 server.2=host2-IP:2888:3888 server.3=host3-IP:2888:3888

    zoo2:
        image: 31z4/zookeeper
        restart: always
        ports:
            - 2182:2181
            - 2888:2888
            - 3888:3888
        environment:
            ZOO_MY_ID: 2
            ZOO_SERVERS: server.1=host1-IP:2888:3888 server.2=host2-IP:2888:3888 server.3=host3-IP:2888:3888

    zoo3:
        image: 31z4/zookeeper
        restart: always
        ports:
            - 2183:2181
            - 2888:2888
            - 3888:3888
        environment:
            ZOO_MY_ID: 3
            ZOO_SERVERS: server.1=host1-IP:2888:3888 server.2=host2-IP:2888:3888 server.3=host3-IP:2888:3888

代码是从以下位置添加的：

我只是尝试使用下一个docker compose，并将zoo1、zoo2和zoo3添加到/etc/hosts文件中：

version: '2'
services:
    zoo1:
        image: 31z4/zookeeper
        restart: always
        ports:
            - 2181:2181
            - 2888:2888
            - 3888:3888
        environment:
            ZOO_MY_ID: 1
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

    zoo2:
        image: 31z4/zookeeper
        restart: always
        ports:
            - 2182:2181
            - 2888:2888
            - 3888:3888
        environment:
            ZOO_MY_ID: 2
            ZOO_SERVERS: server.1=zooo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

    zoo3:
        image: 31z4/zookeeper
        restart: always
        ports:
            - 2183:2181
            - 2888:2888
            - 3888:3888
        environment:
            ZOO_MY_ID: 3
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

但如果我检查状态，它不工作：

./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
Error contacting service. It is probably not running.

暴露端口的左侧是主机的本地端口，只能使用一次。此外，您不需要为容器互连公开端口，因为它们位于同一网络中

因此，移除左侧部分

2888:2888

，保持原样：

2888

，然后docker将在主机中找到一个空闲端口（使用

docker ps

查找它）。如果不需要公开端口，也可以直接删除

端口

问题是什么还不清楚。有关什么是好问题的详细信息，请参见和。@HoriaComan Thank刚刚编辑过真的谢谢，但我只是在不同的主机上使用了它，所以这些端口是免费的，最后在运行几分钟后就可以工作了。
