docker容器端口映射
发布docker容器的web服务查看本地镜像
将镜像启动为容器 new_centos
# docker run --name new_centos -itd centos /bin/bash
进入容器 new_centos中安装vim,epel-release,net-tools,nginx，启动nginx时报错
将容器 new_centos 打包成镜像
# docker commit new_centos centos:nginx
容器映射，进入到容器里，再次启动nginx
# docker run -itd --privileged -e "container=docker" -p 8080:80 centos:nginx /usr/sbin/init
