docker-compose环境下zookeeper单机搭建、集群搭建

一、单机模式

version: '3.1'
services:
  zoo1:
    image: zookeeper:latest
    restart: always
    ports:
      - 2181:2181

二、集群模式

version: '3.1'
services:
  zoo1:
    image: zookeeper:latest
    restart: always
    hostname: zoo1
    ports:
      - 2181:2181
    environment:
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=0.0.0.0:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181
  zoo2:
    image: zookeeper:latest
    restart: always
    hostname: zoo2
    ports:
      - 2182:2181
    environment:
      ZOO_MY_ID: 2
      ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=0.0.0.0:2888:3888;2181 server.3=zoo3:2888:3888;2181
  zoo3:
    image: zookeeper:latest
    restart: always
    hostname: zoo3
    ports:
      - 2183:2181
    environment:
      ZOO_MY_ID: 3
      ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=0.0.0.0:2888:3888;2181
