docker-compose开机自动重启
在生产环境中，整个团队需要发布的容器数量很可能极其庞大，而容器之间的联系和拓扑结构也很可能非常复杂，如果依赖人工记录和维护这样复杂的容器关系，并保障集群正常运行、监控、迁移、高可用等常规运维需求，实在是力不从心。
因此，我们需要一种像Dockerfile定义Docker容器一样能够定义容器集群的编排和部署工具，Compose就是来解决这种问题的工具。
docker-compose的安装
docker-compose的安装非常简单：
2
$ chmod +x /usr/local/bin/docker-compose
docker-compose.yml的编写
这是sdp环境的一个例子

文件的说明文档可以查看这里
开机自动运行
找到/etc/rc.d/rc.local文件,添加以下脚本
其中-f参数是指定docker-compose.yml文件的参数
设置完以后，重启操作系统，耐心等待一会，就可以看到对应的docker容器都启动起来了
