    5. 问题：然后docker ps -a 进行查看, 会发现容器已经退出
    6. 很重要的要说明的一点: Docker容器后台运行,就必须有一个前台进程.
    7. 容器运行的命令如果不是那些一直挂起的命令（比如运行top，tail），就是会自动退出的。
    8.  
    9. 这个是docker的机制问题,比如你的web容器,我们以nginx为例，正常情况下,我们配置启动服务只需要启动响应的service即可。例如
    10. service nginx start
    11. 但是,这样做,nginx为后台进程模式运行,就导致docker前台没有运行的应用,
    12. 这样的容器后台启动后,会立即自杀因为他觉得他没事可做了.
    13. 所以，最佳的解决方案是,将你要运行的程序以前台进程的形式运行
