一、获取Nginx镜像

#docker pull nginx

三、在终端中运行如下命令,在本机9001端口运行Nginx服务器,docker ps 查看刚才运行的 container 的id

#docker run -p 9001:80 -d nginx

#docker ps

[root@server01 ~]# docker ps -a 
CONTAINER ID   IMAGE            COMMAND                  CREATED          STATUS                      PORTS                  NAMES
d79bbc7bc03d   nginx            "/docker-entrypoint.…"   30 seconds ago   Up 29 seconds               0.0.0.0:9001->80/tcp   busy_edison

进入镜像内部(exit或者ctrl+d退出)

root@server01 ~]# docker exec -it busy_edison /bin/bash
root@d79bbc7bc03d:/# ls
bin  boot  dev  docker-entrypoint.d  docker-entrypoint.sh  etc  home  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var

修改容器内部nginx下的html文件

[root@server01 ~]# docker cp index.html busy_edison://usr/share/nginx/html
