通过Docker部署ZooKeeper集群

以3.5.7为例

配置文件：

dataDir=/data
dataLogDir=/datalog
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
admin.enableServer=true
clientPort=2181
server.1=10.163.204.193:2888:3888
server.2=10.163.204.194:2888:3888
server.3=0.0.0.0:2888:3888

docker-compose.yml文件：

version: '3.1'

services:
  zookeeper:
    image: zookeeper:3.5.7
    restart: always
    container_name: zk-3
    volumes:
      - /data/zk/data:/data
      - /data/zk/datalog:/datalog
      - /home/zk/zookeeper-3.5.7/conf/zoo.cfg:/conf/zoo.cfg
    environment:
      ZOO_MY_ID: 3
    ports:
      - 2181:2181
      - 2888:2888
      - 3888:3888
      - 8080:8080

查看集群状态，主从信息

docker exec -it zk-3 bash ./bin/zkServer.sh status
