docker 使用compose安装zookeeper集群

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: ''
services:
  zookeeper1:
    image: zookeeper
    container_name: zk1.cloud
    ports:
        - "2181:2181"
    environment:
      ZOO_MY_ID:
      ZOO_SERVERS: server.=0.0.0.0:: server.=zk2.cloud:: server.=zk3.cloud::
  zookeeper2:
    image: zookeeper
    container_name: zk2.cloud
    ports:
        - "2182:2181"
    environment:
      ZOO_MY_ID:
      ZOO_SERVERS: server.=zk1.cloud:: server.=0.0.0.0:: server.=zk3.cloud::
  zookeeper3:
    image: zookeeper
    container_name: zk3.cloud
    ports:
        - "2183:2181"
    environment:
      ZOO_MY_ID:
      ZOO_SERVERS: server.=zk1.cloud:: server.=zk2.cloud:: server.=0.0.0.0::

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 

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 : \
 --name zk1 \
 --link zk2:zknode2 \
 --link zk3:zknode3 \
 --net foo \
 -e SERVER_ID= \
 -e ADDITIONAL_ZOOKEEPER_1=server.=0.0.0.0:: \
 -e ADDITIONAL_ZOOKEEPER_2=server.=zknode2:: \
 -e ADDITIONAL_ZOOKEEPER_3=server.=zknode3:: \
 zookeeper

docker run -d \
 -p : \
 --name zk2 \
 --link zk1:zknode1 \
 --link zk3:zknode3 \
 --net foo \
 -e SERVER_ID= \
 -e ADDITIONAL_ZOOKEEPER_1=server.=zknode1:: \
 -e ADDITIONAL_ZOOKEEPER_2=server.=0.0.0.0:: \
 -e ADDITIONAL_ZOOKEEPER_3=server.=zknode3:: \
 zookeeper

docker run -d \
 -p : \
 --name zk3 \
 --link zk2:zknode2 \
 --link zk1:zknode1 \
 --net foo \
 -e SERVER_ID= \
 -e ADDITIONAL_ZOOKEEPER_1=server.=zknode1:: \
 -e ADDITIONAL_ZOOKEEPER_2=server.=zknode2:: \
 -e ADDITIONAL_ZOOKEEPER_3=server.=0.0.0.0:: \
 zookeeper
