和之前一样，使用alpine的版本，redis 是3.2.5稳定版本

ENTRYPOINT /usr/local/redis/bin/redis-server /etc/redis/redis.conf现将docker build，而后在做成仓库为其他机器提供：docker build -t redis3.2.5 .`docker tag reids3 10.10.242.23:5000/alpinedocker push 10.10.242.23:5000/alpinedocker仓库使用方法，可参考博客中docker仓库搭建文章：http://www.linuxea.com/1424.html
通常需要6台主机，3主3从，我们是会用3台主机，每台主机2个redis容器，集群完成后，每台主机的两个redis不会是同一个主从配置文件示例：我们需要修改端口号，和ip地址，以及pid的名称等，这里的ip地址使用的docker的hosts模式，这样将会简单的多,拓扑如下：

到此，基本上完成
