问题：启动容器的时候报这个错误   Error response from daemon: driver failed programming external connectivity on endpoint nginx01 (522f7911bc29a70543768b995200d8e217fd65561632fabf55b29086b46acfba): Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use

意思就是80端口被占用了

解决方法：

查看当前占用端口命令

netstat -tanlp

杀死进程

kill 983

然后重新启动就完成了

docker start nginx01
