zookeeper yml配置

version: '3.1'

services:
  zoo1:
    deploy:
      mode: replicated
      replicas: 1
    image: zookeeper:3.4.14
    networks:

    volumes:

    volumes:
      - "/home/zookeeper/conf/zook3:/conf"
      - "/home/zookeeper/data/zook3:/data"
      - "/home/zookeeper/datalog/zook3:/datalog"

networks:
  leek-net:
    external: true

根据上面的配置文件，需要在各个节点上增加配置文件的路径

mkdir -p /home/zookeeper/conf/zook1
mkdir -p /home/zookeeper/conf/zook2
mkdir -p /home/zookeeper/conf/zook3

mkdir -p /home/zookeeper/data/zook1
mkdir -p /home/zookeeper/data/zook2
mkdir -p /home/zookeeper/data/zook3

mkdir -p /home/zookeeper/datalog/zook1
mkdir -p /home/zookeeper/datalog/zook2
mkdir -p /home/zookeeper/datalog/zook3

并且在/home/zookeeper/conf/zook1,/home/zookeeper/conf/zook2,/home/zookeeper/conf/zook3

路径内增加zoo.cfg配置文件

[root@docker-master140 zook1]# cat zoo.cfg 
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10

# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/data/zookeeper
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
