利用docker搭建zookeeper集群

zookeeper镜像下载

docker pull zookeeper

安装docker-compose

curl -L https://github.com/docker/compose/releases/download/1.24.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

创建docker-compose.yml 文件

vi docker-compose.yml

version: '3.1'

services:
  zoo1:
    image: zookeeper:latest
    restart: always
    hostname: zoo1
    container_name: zookeeper_1
    ports:
      - 2181:2181
    volumes:
      - /usr/local/docker_app/zookeeper/zoo1/data:/data
      - /usr/local/docker_app/zookeeper/zoo1/datalog:/datalog
    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:latest
    restart: always
    hostname: zoo2
    container_name: zookeeper_2
    ports:
      - 2182:2181
    volumes:
      - /usr/local/docker_app/zookeeper/zoo2/data:/data
      - /usr/local/docker_app/zookeeper/zoo2/datalog:/datalog
    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:latest
    restart: always
    hostname: zoo3
    container_name: zookeeper_3
    ports:
      - 2183:2181
    volumes:
      - /usr/local/docker_app/zookeeper/zoo3/data:/data
      - /usr/local/docker_app/zookeeper/zoo3/datalog:/datalog
    environment:
      ZOO_MY_ID: 3
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

启动容器

在当前目录下输入以下命令

docker-compose -f docker-compose.yml up -d

查看容器运行状态

docker-compose ps

 Name                  Command               State                     Ports                   
------------------------------------------------------------------------------------------------
zookeeper_1   /docker-entrypoint.sh zkSe ...   Up      0.0.0.0:2181->2181/tcp, 2888/tcp, 3888/tcp
zookeeper_2   /docker-entrypoint.sh zkSe ...   Up      0.0.0.0:2182->2181/tcp, 2888/tcp, 3888/tcp
zookeeper_3   /docker-entrypoint.sh zkSe ...   Up      0.0.0.0:2183->2181/tcp, 2888/tcp, 3888/tcp

进入容器查看

docker exec -it zookeeper_1 /bin/bash
bin/zkServer.sh status

ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
Mode: follower

利用docker创建zookeeper集群就介绍完了。
