docker 使用compose安装zookeeper集群

Posted 2020-09-01 bronk

此基础镜像使用的为zookeeper的官方镜像

docker pull zookeeper

新建文件 docker-compose.yml

version: \'2\'
services:
  zookeeper1:
    image: zookeeper
    container_name: zk1.cloud
    ports:
        - "2181:2181"
    environment:
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=0.0.0.0:2888:3888 server.2=zk2.cloud:2888:3888 server.3=zk3.cloud:2888:3888
  zookeeper2:
    image: zookeeper
    container_name: zk2.cloud
    ports:
        - "2182:2181"
    environment:
      ZOO_MY_ID: 2
      ZOO_SERVERS: server.1=zk1.cloud:2888:3888 server.2=0.0.0.0:2888:3888 server.3=zk3.cloud:2888:3888
  zookeeper3:
    image: zookeeper
    container_name: zk3.cloud
    ports:
        - "2183:2181"
    environment:
      ZOO_MY_ID: 3
      ZOO_SERVERS: server.1=zk1.cloud:2888:3888 server.2=zk2.cloud:2888:3888 server.3=0.0.0.0:2888:3888

 

启动集群

docker-compose up

后台启动

docker-compose up -d

查看启动状态

docker-compose ps

 查看主从关系: 

echo stat | nc www.wenbronk.com 2181

可看另外两个端口  2182, 2183

 

 

还可以在启动时直接指定

docker run -d \\
 -p 2181:2181 \\
 --name zk1 \\
 --link zk2:zknode2 \\
 --link zk3:zknode3 \\
 --net foo \\
 -e SERVER_ID=1 \\
 -e ADDITIONAL_ZOOKEEPER_1=server.1=0.0.0.0:2888:3888 \\
 -e ADDITIONAL_ZOOKEEPER_2=server.2=zknode2:2888:3888 \\
 -e ADDITIONAL_ZOOKEEPER_3=server.3=zknode3:2888:3888 \\
 zookeeper

 

docker run -d \\
 -p 2182:2181 \\
 --name zk2 \\
 --link zk1:zknode1 \\
 --link zk3:zknode3 \\
 --net foo \\
 -e SERVER_ID=1 \\
 -e ADDITIONAL_ZOOKEEPER_1=server.1=zknode1:2888:3888 \\
 -e ADDITIONAL_ZOOKEEPER_2=server.2=0.0.0.0:2888:3888 \\
 -e ADDITIONAL_ZOOKEEPER_3=server.3=zknode3:2888:3888 \\
 zookeeper

 

docker run -d \\
 -p 2183:2181 \\
 --name zk3 \\
 --link zk2:zknode2 \\
 --link zk1:zknode1 \\
 --net foo \\
 -e SERVER_ID=1 \\
 -e ADDITIONAL_ZOOKEEPER_1=server.1=zknode1:2888:3888 \\
 -e ADDITIONAL_ZOOKEEPER_2=server.2=zknode2:2888:3888 \\
