docker pull zookeeper ，默认安装最新的
当出现如下结果时, 表示镜像已经下载完成了:
>>> docker pull zookeeper:latest

latest: Pulling from library/zookeeper

>>> docker images
查看所有镜像，就能看到zookeeper

ZK 镜像的基本使用
启动 ZK 镜像
>>> docker run --name my_zookeeper -d zookeeper:latest
这个命令在后台运行一个 zookeeper 容器, 名字是 my_zookeeper, 并且它默认会导出 2181 端口

>>> docker ps -a

然后可以使用：docker logs -f my_zookeeper，查看 ZK 的运行情况, 输出类似如下内容时, 表示 ZK 已经成功启动了:
>>> docker logs -f my_zookeeper
ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
