在创建镜像时，不能关闭容器，让它处于运行状态，所以要另起一个终端，然后执行

使用新生成的镜像创建容器

[root@localhost ~]# docker run --name t1 -it best2001/c1:v0.1
[root@49676d942358 /]# ls
bin  etc   lib    lost+found  mnt  proc  run   srv  tmp  var
dev  home  lib64  media       opt  root  sbin  sys  usr
[root@49676d942358 /]# /usr/local/nginx/sbin/nginx 
[root@49676d942358 /]# ss -antl
State    Recv-Q   Send-Q     Local Address:Port     Peer Address:Port   Process   
LISTEN   0        128              0.0.0.0:80            0.0.0.0:*  

由此可见，新生成的镜像中是包含了新增的内容的，但是此时有一个问题，那就是容器默认要启动的进程是什么？在这里，默认情况下是启动的sh进程，但我们是要启动一个http站点，所以我们要在创建镜像时将容器默认启动的进程设为httpd，这样一来我们就可以通过新生成的镜像来快速构建一个简单的http站点了。

使用命令查看b1容器启动的默认进程是什么docker inspect

[root@localhost ~]# docker ps
