拉取镜像
docker pull zookeeper:latest

获取镜像基本信息
docker inspect zookeeper

 

 

mkdir /opt/zookeeper -p

vim /opt/zookeeper/Dockerfile

FROM alpine
FROM zookeeper:latest
EXPOSE 2181
EXPOSE 2888
EXPOSE 3888
EXPOSE 8080

 

 

单机
vim /opt/zookeeper/conf/zoo.cfg

dataDir=/data
dataLogDir=/datalog
clientPort=2181
4lw.commands.whitelist=*
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
standaloneEnabled=true
admin.enableServer=true

 

 

vim /opt/zookeeper/docker-compose.yml

version: ‘3.6‘
services:
  zookeeper:
    image: zookeeper:latest
    restart: always
    container_name: zookeeper
    ports:
      - "2181:2181"
      - "2888:2888"
      - "3888:3888"
      - "28080:8080"
    volumes: 
      - "./data:/data"
      - "./datalog:/datalog"
      - "./logs:/logs"

 

 

伪集群

集群模式必须设置clientPort的值

mkdir vim /opt/zookeeper/node1/conf -p
vim /opt/zookeeper/node1/conf/zoo.cfg

dataLogDir=/datalog

server.2=192.168.1.101:2882:3882
server.3=192.168.1.101:2883:3883

 

mkdir vim /opt/zookeeper/node2/conf -p
vim /opt/zookeeper/node2/conf/zoo.cfg

dataDir=/data

集群

集群模式必须设置clientPort的值

 

服务器1、2、3：

vim /opt/zookeeper/conf/zoo.cfg

dataDir=/data
dataLogDir=/datalog
clientPort=2181
4lw.commands.whitelist=*
tickTime=2000
initLimit=5
syncLimit=2

  zookeeper:
    image: zookeeper:latest
    restart: always
    container_name: zookeeper
    network_mode: "host"
    ports:
      - "2181:2181"
      - "2888:2888"
      - "3888:3888"
      - "28080:8080"
    environment:
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=192.168.1.101:2888:3888 server.2=192.168.1.102:2888:3888 server.3=192.168.1.103:2888:3888

服务器2：

vim /opt/zookeeper/docker-compose.yml

version: ‘3.6‘
services:
  zookeeper:
    image: zookeeper:latest
    restart: always
    container_name: zookeeper
    network_mode: "host"
    ports:
      - "2181:2181"
      - "2888:2888"
      - "3888:3888"
      - "28080:8080"

      - "./conf/zoo.cfg:/conf/zoo.cfg"
      - "./data:/data"
      - "./datalog:/datalog"
      - "./logs:/logs"

 

服务器3：

vim /opt/zookeeper/docker-compose.yml

version: ‘3.6‘
services:
  zookeeper:
    image: zookeeper:latest
    restart: always
    container_name: zookeeper
    network_mode: "host"
    ports:
      - "2181:2181"
      - "2888:2888"
      - "3888:3888"
      - "28080:8080"
    environment:
      ZOO_MY_ID: 3
      ZOO_SERVERS: server.1=192.168.1.101:2888:3888 server.2=192.168.1.102:2888:3888 server.3=192.168.1.103:2888:3888
    volumes: 
      - "./conf/zoo.cfg:/conf/zoo.cfg"
      - "./data:/data"
      - "./datalog:/datalog"
      - "./logs:/logs"

ZOO_SERVERS中的zookeeper为容器名

 

启动

cd /opt/zookeeper
docker-compose build
docker-compose up -d --force-recreate
docker-compose down
docker-compose restart

 

查看日志

docker logs --tail="500" zookeeper

 

备份配置文件

docker cp zookeeper:/conf/zoo.cfg /opt/zookeeper/conf/zoo_bak.cfg

 

进入容器

docker exec -it zookeeper /bin/bash

 

检查容器状态

docker exec -it zookeeper1 /bin/bash ./bin/zkServer.sh status
