一 下载zookeeper包
http://apache.osuosl.org/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz
二 制作zookeeper的Docker image
1 采用ubuntu16.04基础image,并对此image安装jdk1.8
2 把zookeeper-3.4.9.tar.gz加压后通过文件挂载的方式传入基础image中，配置$ZOOKEEPER_HOME，但把$ZOOKEEPER_HOME/zookeeper-3.4.9/conf，接着commit image，命名为zookeeper:1.0
3 基于zookeeper:1.0制作正规的zookeeper image zookeeper:2.0
Dockerfile：
FROM zookeeper:1.0 MAINTAINER dean ENV JAVA_HOME /usr/local/java/ ENV ZOOKEEPER_HOME /opt/tools/zookeeper/zookeeper-3.4.9 ENV JRE_HOME $JAVA_HOME/jre ENV CLASSPATH .:$JAVA_HOME/lib:$JRE_HOME/lib ENV PATH $PATH:$JAVA_HOME/bin
4 启动docker集群
docker run -d -i -t -p 2181:2181 -p 2887:2887 -p 3887:3887 -v /usr/local/zookeeper/zookeeperServer1:/opt/tools/zookeeper/zookeeper-3.4.9/conf -v /usr/local/zookeeper/zookeeperServer1/data:/usr/local/zookeeperLog zookeeper:2.0 /bin/bash
docker run -d -i -t -p 2182:2182 -p 2888:2888 -p 3888:3888 -v /usr/local/zookeeper/zookeeperServer2:/opt/tools/zookeeper/zookeeper-3.4.9/conf -v /usr/local/zookeeper/zookeeperServer2/data:/usr/local/zookeeperLog/ zookeeper:2.0 /bin/bash
docker run -d -i -t -p 2183:2183 -p 2889:2889 -p 3889:3889 -v /usr/local/zookeeper/zookeeperServer3:/opt/tools/zookeeper/zookeeper-3.4.9/conf -v /usr/local/zookeeper/zookeeperServer3/data:/usr/local/zookeeperLog zookeeper:2.0 /bin/bash
值得注意的是zookeeper的配置文件
server1
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/usr/local/zookeeperLog/
dataLogDir=/usr/local/zookeeperLog/
# the port at which the clients will connect
clientPort=2181
server.1=0.0.0.0:2887:3887
server.2=10.108.68.140:2888:3888
server.3=10.108.68.140:2889:3889
server2

server.2=10.108.68.140:2888:3888
server.3=0.0.0.0:2889:3889
最后通过zkCli.sh -server 10.108.68.140:2181检查一下集群的运行情况
